How to make a dotnet webservice set minOccurs="1" on a string value
|
<p>I have an XSD:</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns="http://a.com/a.xsd"
targetNamespace="http://a.com/a.xsd"
elementFormDefault="qualified"
attributeFormDefault="unqualified">
<xs:element name="A">
<xs:complexType>
<xs:sequence>
<xs:element name="Item" minOccurs="1" maxOccurs="1">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:minLength value="1"/>
<xs:whiteSpace value="collapse"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
</code></pre>
<p>Which I have converted into a C# class using XSD.exe v2.0.50727.3615 which generates code as follows</p>
<pre><code>namespace A {
using System.Xml.Serialization;
/// <remarks/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "2.0.50727.42")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true, Namespace="http://a.com/a.xsd")]
[System.Xml.Serialization.XmlRootAttribute(Namespace="http://a.com/a.xsd", IsNullable=false)]
public partial class A {
private string itemField;
/// <remarks/>
public string Item {
get {
return this.itemField;
}
set {
this.itemField = value;
}
}
}
}
</code></pre>
<p>I am returning an A.A object in my webservice, which produces this snippet in the service description</p>
<pre><code><s:schema elementFormDefault="qualified" targetNamespace="http://a.com/a.xsd">
<s:element name="Test2Result">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="Item" type="s:string" />
</s:sequence>
</s:complexType>
</s:element>
</s:schema>
</code></pre>
<p>The change from minOccrus="1" in the XSD to minOccurs="0" on the auto-generated WSDL is causing grief to the machine on the other end of the system.</p>
<p>I could of course provide a hand edited WSDL for them to use, but I would like the auto-generated one to suit their needs.</p>
<p>Any suggestions on how to convince dotnet to output minOccurs="1" for a string type in its autogenerated WSDLs without also adding nillable="true"?</p>

Row-major vs Column-major confusion
|
<p>I've been reading a lot about this, the more I read the more confused I get.</p>
<p>My understanding: In row-major rows are stored contiguously in memory, in column-major columns are stored contiguously in memory. So if we have a sequence of numbers <code>[1, ..., 9]</code> and we want to store them in a row-major matrix, we get:</p>
<pre><code>|1, 2, 3|
|4, 5, 6|
|7, 8, 9|
</code></pre>
<p>while the column-major (correct me if I'm wrong) is:</p>
<pre><code>|1, 4, 7|
|2, 5, 8|
|3, 6, 9|
</code></pre>
<p>which is effectively the transpose of the previous matrix.</p>
<p>My confusion: Well, I don't see any difference. If we iterate on both the matrices (by rows in the first one, and by columns in the second one) we'll cover the same values in the same order: <code>1, 2, 3, ..., 9</code></p>
<p>Even matrix multiplication is the same, we take the first contiguous elements and multiply them with the second matrix columns. So say we have the matrix <code>M</code>:</p>
<pre><code>|1, 0, 4|
|5, 2, 7|
|6, 0, 0|
</code></pre>
<p>If we multiply the previous row-major matrix <code>R</code> with <code>M</code>, that is <code>R x M</code> we'll get:</p>
<pre><code>|1*1 + 2*0 + 3*4, 1*5 + 2*2 + 3*7, etc|
|etc.. |
|etc.. |
</code></pre>
<p>If we multiply the column-major matrix <code>C</code> with <code>M</code>, that is <code>C x M</code> by taking the columns of <code>C</code> instead of its rows, we get exactly the same result from <code>R x M</code></p>
<p>I'm really confused, if everything is the same, why do these two terms even exist? I mean even in the first matrix <code>R</code>, I could look at the rows and consider them columns...</p>
<p>Am I missing something? What does row-major vs col-major actually imply on my matrix math? I've always learned in my Linear Algebra classes that we multiply rows from the first matrix with columns from the second one, does that change if the first matrix was in column-major? do we now have to multiply its columns with columns from the second matrix like I did in my example or was that just flat out wrong?</p>
<p>Any clarifications are really appreciated!</p>
<p><strong>EDIT:</strong> One of the other main sources of confusion I'm having is GLM... So I hover over its matrix type and hit F12 to see how it's implemented, there I see a vector array, so if we have a 3x3 matrix we have an array of 3 vectors. Looking at the type of those vectors I saw 'col_type' so I assumed that each one of those vectors represent a column, and thus we have a column-major system right?</p>
<p>Well, I don't know to be honest. I wrote this print function to compare my translation matrix with glm's, I see the translation vector in glm at the last row, and mine is at the last column... </p>
<p><a href="https://i.stack.imgur.com/qMxjQ.png" rel="noreferrer"><img src="https://i.stack.imgur.com/qMxjQ.png" alt="enter image description here"></a></p>
<p>This adds nothing but more confusion. You can clearly see that each vector in <code>glmTranslate</code> matrix represents a row in the matrix. So... that means that the matrix is row-major right? What about my matrix? (I'm using a float array[16]) the translation values are in the last column, does that mean my matrix is column-major and I didn't now it? <em>tries to stop head from spinning</em></p>

How do I write multiple objects to the serializable file and read them when the program is used again?

<p>I want to maintain database of users of a Bank for my project. I am able to save the number of users in one serializable file. But when I try to save the user to database it adds only the latest one to database.</p>
<p>Below is the sneak peak of code which writes the objects:</p>
<pre><code>if(e.getSource()==submit) {
if(uFName != null && uLName != null && uInitialDeposit !=0) {
if(uAccountType=="Savings") {
Random randomGenerator = new Random();
//Gets the number of users from file if file exists
File f = new File(fileNameAdmin);
if(f.exists() && !f.isDirectory()) {
admin=db.readFromAdminDatabase();
}
u[admin.numberOfUsers]= new User();
u[admin.numberOfUsers].fName=uFName;
u[admin.numberOfUsers].lName=uLName;
u[admin.numberOfUsers].initalDeposit=uInitialDeposit;
u[admin.numberOfUsers].interestRate=uInterestRate;
u[admin.numberOfUsers].accountType="Saving";
u[admin.numberOfUsers].accountNumber=690000+admin.numberOfSavingsAccount;
//Generates a 4 digit random number which will be used as ATM pin
u[admin.numberOfUsers].atmPin=randomGenerator.nextInt(9999-1000)+1000;
//A savings account will be created
sa[admin.numberOfSavingsAccount]=new SavingsAccount(u[admin.numberOfUsers].accountNumber,u[admin.numberOfUsers].fName,u[admin.numberOfUsers].lName,
u[admin.numberOfUsers].initalDeposit,
u[admin.numberOfUsers].interestRate);
u[admin.numberOfUsers].sa=sa[admin.numberOfSavingsAccount];
System.out.println(u[admin.numberOfUsers].sa.balance);
JOptionPane.showMessageDialog(submit,"Congratulations! You are now a member of Symbiosis Bank."
+ "\nYour account number is "+u[admin.numberOfUsers].accountNumber
+" and your ATM Pin is "+u[admin.numberOfUsers].atmPin,"Account Created",JOptionPane.INFORMATION_MESSAGE);
try {
//for(int j = 0; j<admin.numberOfUsers; j++)
db.addUserToDatabase(u[admin.numberOfUsers]);
admin.numberOfSavingsAccount++;

Twitter Bootstrap carousel not working

How to create a vertical carousel using plain JavaScript and CSS
|
<p>I am trying to create a vertical carousel using vanilla JavaScript and CSS. I know that jQuery has a carousel library but I want to have a go at building this from scratch using no external libraries. I started off by just trying to move the top image and then I planned to move on to making the next image move. I got stuck on the first image. This is where I need your help, StackOverflowers.</p>
<p>My HTML:</p>
<pre><code><div class="slider vertical" >
<img class="first opened" src="http://malsup.github.io/images/beach1.jpg">
<img class="opened" src="http://malsup.github.io/images/beach2.jpg">

<img src="http://malsup.github.io/images/beach9.jpg">
</div>
<div class="center">
<button id="prev">∧ Prev</button>
<button id="next">∨ Next</button>
</div>
</code></pre>
<p>JavaScript:</p>
<pre><code>var next = document.getElementById('next');
var target = document.querySelector('.first');
next.addEventListener('click', nextImg, false);
function nextImg(){
if (target.classList.contains('opened')) {
target.classList.remove('opened');

Hibernate: how to call a stored function returning a varchar?
|
<p>I am trying to call a legacy stored function in an Oracle9i DB from Java using Hibernate. The function is declared like this:</p>
<pre><code>create or replace FUNCTION Transferlocation_Fix (mnemonic_code IN VARCHAR2)
RETURN VARCHAR2
</code></pre>
<p>After several failed tries and extensive googling, I found <a href="https://forum.hibernate.org/viewtopic.php?f=1&t=976887&view=previous" rel="nofollow noreferrer">this thread</a> on the Hibernate forums which suggested a mapping like this:</p>
<pre><code><sql-query name="TransferLocationFix" callable="true">
<return-scalar column="retVal" type="string"/>
select Transferlocation_Fix(:mnemonic) as retVal from dual
</sql-query>
</code></pre>
<p>My code to execute it is</p>
<pre><code> Query query = session.getNamedQuery("TransferLocationFix");
query.setParameter("mnemonic", "FC3");
String result = (String) query.uniqueResult();
</code></pre>
<p>and the resulting log is</p>
<pre><code>DEBUG (org.hibernate.jdbc.AbstractBatcher:366) - - about to open PreparedStatement (open PreparedStatements: 0, globally: 0)
DEBUG (org.hibernate.SQL:401) - - select Transferlocation_Fix(?) as retVal from dual

<p>Any clues what am I doing wrong? Or any better ways to call this stored function?</p>
<hr>
<p><strong>Update:</strong> upon trying @axtavt's suggestion, I get the following error:</p>
<pre><code>ORA-14551: cannot perform a DML operation inside a query
</code></pre>
<p>The function indeed does extensive inserts/updates, so I guess the only way to run it would be using the stored procedure syntax. I just have no clue how to map the return value:</p>
<pre><code><sql-query name="TransferLocationFix" callable="true">
<return-scalar column="???" type="string"/>
{ ? = call Transferlocation_Fix(:mnemonic) }
</sql-query>
</code></pre>
<p>What should be the <code>column</code>? I will try an empty value...</p>
<hr>
<p><strong>Update2:</strong> that failed as well, with an SQL Grammar Exception... So I tried the JDBC way as suggested by Pascal, and it seems to work! I added the code in an answer below.</p>

Login request validation token issue
|
<p>I have been going through the error logs of a development project and found the following error (name changed to protect the <strike>guilty</strike> innocent)-</p>
<blockquote>
<p>The provided anti-forgery token was meant for user "", but the current
user is "admin".</p>
</blockquote>
<p>This was not an especially difficult issue to reproduce-</p>
<ol>
<li>Open the application at the login page</li>
<li>Open a second window or tab in the <strong>same browser</strong> on the <strong>same computer</strong> to the login page before logging in</li>
<li>Login in the first window (or indeed second, the order doesn't matter)</li>
<li>Attempt to login in the remaining login window</li>
</ol>
<p>The stack trace is-</p>
<blockquote>
<p>System.Web.Mvc.HttpAntiForgeryException (0x80004005): The provided
anti-forgery token was meant for user "", but the current user is
"admin". at

at
System.Web.Mvc.Async.AsyncControllerActionInvoker.<>c__DisplayClass25.b__1e(AsyncCallback
asyncCallback, Object asyncState)</p>
</blockquote>
<p>The login method signature is-</p>
<pre><code>[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public ActionResult Login(LoginModel model, string returnUrl)
{
...
}
</code></pre>
<p>This is exactly the same as the signature for the method in a internet "ASP.NET MVC 4 Web Application" templated project, which indicates that Microsoft either felt the ValidateAntiForgeryToken was necessary/best practice, or simply added the attribute here because it was used everywhere else.</p>
<p>Obviously there is nothing I can do to handle the problem <em>within</em> this method as it isn't reached, the ValidateAntiForgeryToken is a pre-request filter and it is blocking the request before it reaches the controller.</p>
<p>I could check if the user is authenticated via Ajax before submitting the form and attempt to redirect to them if so, or simply remove the attribute.</p>
<p>The question is this - I understand that the token is design to prevent requests from another site (CSRF) when the user <em>is already authenticated against your site</em> so on that basis <strong>is it an issue to remove it from a form which by definition will be used by unauthenticated users</strong>? </p>
<p>Presumably the attribute in this instance is designed to mitigate malicious actors providing fake login forms for your application (although by the time the exception is thrown presumably the user has already entered his or her details which will have been recorded - but it might alert them something is wrong). Otherwise submitting incorrect credentials to the form from an external site will result in exactly the same result as on the site itself surely? I am not relying on client validation/sanitation to clean up potentially unsafe input.</p>
<p>Have other devs come across this issue (or do we have unusually creative users) and if so how have you resolved/mitigated it?</p>
<p><strong>Update:</strong> This issue still exists in MVC5, entirely intentionally, now with the error message "The provided anti-forgery token was meant for a different claims-based user than the current user." when using default template and Identity providers. There is a relevant question and interesting answer from Microsoft Developer Evangelist and Troy's fellow PluralSight author Adam Tuliper at <a href="https://stackoverflow.com/questions/9433083/anti-forgery-token-on-login-page">Anti forgery token on login page</a> which recommends simply removing the token.</p>

MySQL MAX from SUM
|
<p>This is freaking me out!
Got the following data:</p>
<pre><code>+----+-----+-------+------------+

| 2 | 1C | 200 | 2009-03-01 |
+----+-----+-------+------------+
</code></pre>
<p><strong>PS {edit 0001}</strong> :: there's an extra field, which also must be used for filter data, call it {TYPE}, an could get 'SINGLE' or 'MULTIPLE' as value.</p>
<p>I want to get the MAX between SUM(of each different {REG}) for every {ID}. Obviously, this is a simple representation, table got up to 64985928 registers and {DATE} is the filtering data.</p>
<p>That will be, 1st step get the SUM for each {REG}:</p>
<pre><code>+----+------+
| ID | SUM |
+----+------+
| 1 | 300 |
| 2 | 300 |
| 2 | 400 |
+----+------+
</code></pre>
<p>That's: </p>
<pre><code>SELECT
SUM(value)
FROM
table
WHERE
(date BETWEEN '2009-01-01' AND '2009-03-01')
GROUP BY
reg;
</code></pre>
<p>And then, get the MAX from each SUM, which is where I'm stucked:</p>
<pre><code>+----+------+
| ID | MAX |
+----+------+
| 1 | 300 |
| 2 | 400 |
+----+------+
</code></pre>
<p>I've tried:</p>
<pre><code>SELECT
a.id,
MAX(b.sum)
FROM
table a,
(SELECT
SUM(b.value)
FROM
table b
WHERE
(b.date BETWEEN '2009-01-01' AND '2009-03-01') AND (a.id = b.id)
GROUP BY
b.reg);
</code></pre>
<p>Any idea?
PS: Sorry for mistakes.</p>
<p><strong>PS {edit 0002}</strong> Gonna copy original queries and data, so may it helps better.</p>

Gradle jacoco code coverage - Then publish/show in Jenkins
|
<p>I'm trying to setup code coverage for a Java application project.</p>
<p>Project name : NewApp</p>
<p>Project structure: </p>
<ul>
<li>src/java/** (source code)</li>
<li>src/java-test (unit tests - Jnuit)</li>
<li>test/it-test (integration test)</li>
<li>test/at-tests (acceptance tests)</li>
<li>tomcat/* (contain tomcat start/stop scripts)</li>
<li>xx/.. etc folders which are required for a usual application.</li>
</ul>
<p>Gradle version : 1.6</p>
<p>Environment : Linux</p>
<p>I have a running gradle build script that fetches application (NewApp) dependencies (i.e. service jars used by the app for build process) from a build artifact repository (artifactory/maven for ex), and builds the app.</p>
<p>Now at this point, I wanted to get code coverage using JaCoCo plugin for my NewApp application project.</p>
<p>I followed the documentation per Gradle/Jacoco but it doesn't seems to create any reports/... folder for jacoco etc where I can find what Jacoco coverage report did.</p>
<p>My questions:
1. For getting code coverage using Unit tests (Junit), I assume all I have to do is the following and it will NOT require me to start/stop the tomcat before running unit test (test task i.e. "gradle test") to get code coverage for/via using unit tests. Please advise/correct. The code (just for Gradle jacoco unit test part) - I'm using is:</p>
<pre><code>apply plugin: 'jacoco'
test {
include 'src/java-test/**'
}
jacocoTestReport {
group = "reporting"
description = "Generate Jacoco coverage reports after running tests."
reports {
xml.enabled true
html.enabled true
csv.enabled false
}
//classDirectories = fileTree(dir: 'build/classes/main', include: 'com/thc/**')
//sourceDirectories = fileTree(dir: 'scr/java', include: 'com/thc/**')
additionalSourceDirs = files(sourceSets.main.allJava.srcDirs)
}
</code></pre>
<p>and for Integration tests:</p>
<pre><code>task integrationTest(type: Test) {
include 'test/java/**'
}
</code></pre>
<p>As jacocoTestReport is depends upon test task(s), thus they will be called first and then finally jacocoTestReport will report what it found for the code coverage.</p>
<ol>
<li>For getting code coverage for integration tests, I assume I must start tomcat first (i.e. before running / calling test target for integration tests), then call "gradle integrationTest" or "gradle test" task and then stop tomcat -- to get the code coverage report. From other blog posts I also found that one should setup JAVA_OPTS variable to assign jacoco agent before tomcat starts.</li>
</ol>
<p>for ex: setting JAVA_OPTS variable like:</p>
<pre><code>export JACOCO="-Xms256m -Xmx512m -XX:MaxPermSize=1024m -javaagent:/production/jenkinsAKS/jobs/NewApp/workspace/jacoco-0.6.3.201306030806/lib/jacocoagent.jar=destfile=/production/jenkinsAKS/jobs/NewApp/workspace/jacoco/jacoco.exec,append=true,includes=*"
export JAVA_OPTS="$JAVA_OPTS $JACOCO"
</code></pre>
<ol>
<li><p>Being new to Gradle/groovy - I'm not sure what code should I write within build.gradle (build script) to get the above Integration/Unit tests working if it involves start/stop of tomcat. If someone can provide a sample script to do that, I'll try.</p></li>
<li><p>I'm not getting any code coverage right now, when I publish Jacoco code coverage in Jenkins (using Jenkins post build action for publishing Jacoco reports). Jenkins build dashboard shows 0% for code coverage (i.e. bars showing all red color, no green for actual code coverage).</p></li>
</ol>
<p>Need your advice to get some traction on this.</p>

<p>Cleaning or "Update Maven Project" makes no difference.</p>

<p>python3 isnt recognized by jenkins as it hasnt been installed yet. How do i get a python3 installation in my jenkins folder? I tried making the changes here - but for some reason - this doesnt seem to work (using the <code>shiningpanda</code> plugin)</p>
<p><a href="https://i.stack.imgur.com/utVmI.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/utVmI.png" alt="enter image description here"></a></p>
<p>python2.7 actually does exist in <code>/usr/bin/python</code> but this seem to be unrecognized by Jenkins</p>

<p>I am installing a certain NodeJS script - <a href="http://caressjs.com/" rel="noreferrer">Caress</a>. But i am not unable to. I am using Windows 8.1, can anyone tell me what is the problem i am facing, and why is this installation not working. There seems to be a problem with the buffertools dependency, thats far as i can think. Dont know how maybe fix this?</p>
<p>If i download the build from github and place it in node-modules, nothing seems to work. when i try to start, using npm start, or during implementation either.</p>

Translate validation message in laravel 5
|
<p>I have a problem translating the laravel messages. I have created a folder called <code>es</code> inside <code>lang</code> folder and I have translated the messages from English to Spanish. Also I have set <code>'locale' => 'es'</code> on <code>config/app.php</code>. But English messages continues appearing.</p>
<p>I have used the default views for login provided by laravel, to generate it (and routes) I used the command (as says in <a href="https://laravel.com/docs/5.2/authentication" rel="noreferrer">https://laravel.com/docs/5.2/authentication</a>)</p>
<p><code>php artisan make:auth</code></p>
<p>I have changed the default routes by the following:</p>
<pre><code>Route::get('/login', 'UserController@getLogin');
Route::post('/login', 'UserController@postLogin');
</code></pre>
<p>And in UserController I have:</p>
<pre><code>public function getLogin(){
return view('auth.login');
}
public function postLogin(Request $request){
$input = $request->all();
if (Auth::attempt(['email' => $input["email"], 'password' => $input["password"]], true))
{
return redirect()->intended('/tables');
}
}
</code></pre>
<p>Here are two screenshots of the messages that appears in English</p>
<p><a href="http://i64.tinypic.com/if4k83.png" rel="noreferrer">http://i64.tinypic.com/if4k83.png</a></p>
<p><a href="http://i64.tinypic.com/51zhnp.png" rel="noreferrer">http://i64.tinypic.com/51zhnp.png</a></p>

Header, footer and large tables with iTextSharp
|
<p>I've added an header and a footer on my document by PdfPageEventHelper.</p>
<p>The document has several "large" tables populated at runtime.</p>
<p>I've tried to add those tables simply by "documen.Add(table)", but my header and my footer results overwritten.</p>
<p>I've already tried both methods to add the tables (WriteSelectedRows and document.Add(myPdfPtable).</p>
<p>Here is the code of the PageEventHelper:</p>
<pre><code>private class MyPageEventHandler : PdfPageEventHelper
{
public iTextSharp.text.Image ImageHeader { get; set; }
public iTextSharp.text.Image ImageFooter { get; set; }
public override void OnEndPage(PdfWriter writer, Document document)
{
var fontintestazione = FontFactory.GetFont("Verdana", 10, Font.BOLD, BaseColor.LIGHT_GRAY);
var fontRight = FontFactory.GetFont("Verdana", 8, Font.BOLD, BaseColor.WHITE);
var fontFooter = FontFactory.GetFont("Verdana", 6, Font.NORMAL, BaseColor.BLUE);
float cellHeight = document.TopMargin;
Rectangle page = document.PageSize;
PdfPTable head = new PdfPTable(3);
head.TotalWidth = page.Width;
PdfPCell c = new PdfPCell(ImageHeader, true);
c.HorizontalAlignment = Element.ALIGN_LEFT;
c.FixedHeight = cellHeight;
c.Border = PdfPCell.NO_BORDER;
head.AddCell(c);
c = new PdfPCell(new Phrase("somePhrase", fontintestazione));
c.Border = PdfPCell.NO_BORDER;
head.AddCell(c);
c = new PdfPCell(new Phrase("someTextBlah", fontRight));
c.Border = PdfPCell.NO_BORDER;
c.HorizontalAlignment = 1;
c.BackgroundColor = new BaseColor(70, 130, 180);
head.AddCell(c);
head.WriteSelectedRows(0, -1, 10, page.Height - cellHeight + head.TotalHeight -30, writer.DirectContent);
PdfPTable footer = new PdfPTable(2);
footer.TotalWidth = 316f;
float[] cfWidths = new float[] { 2f, 1f };
footer.SetWidths(cfWidths);
PdfPCell cf = new PdfPCell(ImageFooter, true);
cf.HorizontalAlignment = Element.ALIGN_RIGHT;
cf.FixedHeight = cellHeight;
cf.Border = PdfPCell.NO_BORDER;
footer.AddCell(cf);
cf = new PdfPCell(new Phrase("someEndingText", fontFooter));
cf.HorizontalAlignment = Element.ALIGN_LEFT;
cf.Border = PdfPCell.NO_BORDER;
footer.AddCell(cf);
footer.WriteSelectedRows(0, -1, 10, 50, writer.DirectContent);
}
</code></pre>
<p>On my page, i simply do:</p>
<pre><code>var document = new Document(PageSize.A4);
var output = new MemoryStream();
var writer = PdfWriter.GetInstance(document, output);
iTextSharp.text.Image imageHeader = iTextSharp.text.Image.GetInstance(Server.MapPath("/images/header.ong"));
iTextSharp.text.Image imageFooter = iTextSharp.text.Image.GetInstance(Server.MapPath("/images/footer.png"));
MyPageEventHandler eve = new MyPageEventHandler
{
ImageHeader = imageHeader ,
ImageFooter = imageFooter
};
writer.PageEvent = eve;
document.Open();
//adding a table
PdfPTable cvTable = new PdfPtable(3);
cvTable.TotalWidth = document.PageSize.Width;
PdfPCell hCell = new PdfPCell(new Phrase("Jobs By User", aCustomFont));
cvTable.AddCell(hCell);
for(int i = 0; i < myTable.Records.Count; i++)
{
PdfPCell idCell = new PdfPCell(new Phrase(myTable.Records[i]._id, aFont));
cvTable.Add(idCell);
//same stuff for other fields of table
}
//first attempt.... failed:
document.Add(cvTable) //<- header and footer are overwritten by table
//second attempt..... failed too...
cvTable.WriteSelectedRows(0, -1, 10, myPoisition, writer.DirectContent);
//kind of fail...:
//the table is large and need more pages. It is trunked on the first page and overwrite
//the footer.

Hello world with boost python and python 3.2
|
<p>So I'm trying to interface python 3.2 and c++ using boost python, and have come across many many issues. I've finally gotten it to compile using the 2.7 libraries and it works, but I can't seem to make it work with python 3.2. </p>
<p>Here's the c++ code</p>
<pre><code>#include <iostream>
using namespace std;
void say_hello(const char* name) {
cout << "Hello " << name << "!\n";
}
int main(){return 0;}
#include <boost/python/module.hpp>
#include <boost/python/def.hpp>
using namespace boost::python;
BOOST_PYTHON_MODULE(hello)
{
def("say_hello", say_hello);
}
</code></pre>
<p>If I compile it using the 2.7 libraries it works just fine, but when I use the 3.2 libraries I get tons of undefined references from libboost_python.so</p>
<p>Otherwise I wrote a little bit of python to make it work:</p>
<pre><code>from distutils.core import setup
from distutils.extension import Extension
setup(name="PackageName",
ext_modules=[
Extension("hello", ["testBoost.cpp"],
libraries = ["boost_python"])
])
</code></pre>
<p>and this will create an so using python 3.2 or 2.7 build, but when I open the python 3 interpreter and attempt to import the so it give me the error undefined symbol PyClass_Type from libboost_python.so again. Any ideas? Is boost python compatible with python 3.x?</p>
<p>If the information is useful, here is my attempted compile using 3.2:</p>
<pre><code> $ g++ testBoost.cpp -I/usr/include/python3.2 -I/usr/local/include/boost/python -lboost_python -lpython3.2mu
/tmp/ccdmU1Yu.o: In function `PyInit_hello':

collect2: ld returned 1 exit status
</code></pre>
<p>And the error from the python 3 interpreter is</p>
<pre><code>File "<stdin>", line 1, in <module>
ImportError: /usr/local/lib/libboost_python.so.1.47.0: undefined symbol: PyClass_Type
</code></pre>
<p>Thanks for any help!</p>

Connecting to a SQL server using ADODB from a C# dll
|
<p>I am writing a custom <code>Connection</code> class in C# for Excel to be able to connect to a SQL Server.
When I use <code>SQLConnection</code> from <code>System.Data.SqlClient</code> library I am able to establish a connection. The working code I've got:</p>
<pre><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Data.SqlClient;
using System.Runtime.InteropServices;
namespace Test
{
[InterfaceType(ComInterfaceType.InterfaceIsDual),
Guid("6E8B9F68-FB6C-422F-9619-3BA6D5C24E84")]
public interface IConnection
{
bool Status { get; }
bool Open();
}
[ClassInterface(ClassInterfaceType.None)]
[Guid("B280EAA4-CE11-43AD-BACD-723783BB3CF2")]
[ProgId("Test.Connection")]
public class Connection : IConnection
{
private bool status;
private SqlConnection conn;
private string connString = "Data Source=[server]; Initial Catalog=[initial]; User ID=[username]; Password=[password]";
public Connection()
{
}
public bool Status
{
get
{
return status;
}
}
public bool Open()
{
try
{
conn = new SqlConnection(connString);
conn.Open();
status = true;
return true;
}
catch(Exception e)
{
e.ToString();
return false;
}
}
}
}
</code></pre>
<p>And after adding the reference to Excel I am able to test the connection using a simple VBA code like this:</p>
<pre><code>Sub TestConnection()
Dim conn As Test.Connection
Set conn = New Test.Connection
Debug.Print conn.Status
conn.Open
Debug.Print conn.Status
End Sub
</code></pre>
<p>It outputs:</p>
<blockquote>
<p>False <br>
True <br></p>
</blockquote>
<p>So everything is fine. Now I would like to create custom <code>Recordset</code> class in my C# library so I decided to use an <code>ADODB</code> library and its <code>RecordSet</code>instead of <code>SqlDataReader</code> as I am planning to work with some big chunks of data. So, I have modified my code to this:</p>
<pre><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Data.SqlClient;
using System.Runtime.InteropServices;
namespace Test
{
[InterfaceType(ComInterfaceType.InterfaceIsDual),
Guid("6E8B9F68-FB6C-422F-9619-3BA6D5C24E84")]
public interface IConnection
{
bool Status { get; }
bool Open();
}
[ClassInterface(ClassInterfaceType.None)]
[Guid("B280EAA4-CE11-43AD-BACD-723783BB3CF2")]
[ProgId("Test.Connection")]
public class Connection : IConnection
{
private bool status;
private ADODB.Connection conn = new ADODB.Connection();
private string connString = "Data Source=[server]; Initial Catalog=[initial]; User ID=[username]; Password=[password]";
public Connection()
{
}
public bool Status
{
get
{
return status;
}
}
public bool Open()
{
try
{
conn.ConnectionString = connString;
conn.Open();
// conn.Open(connString, ["username"], ["password"], 0)
// what else can I try? is this where it actually fails?
status = true;
return true;
}
catch (Exception e)
{
e.ToString();
return false;
}
}
}
}
</code></pre>
<p>I also have added references to <code>Microsoft ActiveX Data Objects 6.1 Library</code>.</p>
<p>Now, when I am executing the VBA code it outputs:</p>
<blockquote>
<p>0 <br>
0 <br></p>
</blockquote>
<p>But I was expecting <code>0</code> and <code>1</code>. It seems to me like I am not properly connecting to the server <em>( credentials are the same i have just removed actual data from this code )</em>.
<br></p>
<p>I have tried to use different variations of the connection string, however it always returns <code>0</code> and <code>0</code>. I have tried creating a new project with new GUIDs and also tried renaming the projects, classes, etc. nothing has worked. I am suspecting its the establishment of the connection but I am unsure how to debug a dll.</p>
<p>I have used <a href="http://support.microsoft.com/kb/308611" rel="nofollow">link1</a>, <a href="http://msdn.microsoft.com/en-us/library/ms807027.aspx" rel="nofollow">link2</a>, <a href="http://msdn.microsoft.com/en-us/library/ms130978.aspx" rel="nofollow">link3</a>, <a href="http://homeofcox-cs.blogspot.co.uk/2009/07/use-adodbrecordset-in-c.html" rel="nofollow">link4</a> for reference<br></p>
<p><strong>Update:</strong><br>
I have wrote the exception to the file as TheKingDave suggested. This is the exception error message</p>
<blockquote>
<p>System.Runtime.InteropServices.COMException (0x80004005):

How to find the "last page" in a view pager. Or the total 'number' of views. Android Development
|
<p>Thank you for your help in advanced. And sorry if this is a very silly question, but I cannot find it elsewhere.
What I want, is basically, to determine the total amount of pages I have in my ViewPager when it is all set up, like in my code. I have tried (on a later version) adding the "size variable" to f as it's argument (see, FirstFragment). It's not a known number, as the user input's the number of forms (view's) I will create, and passes it to FirstFragment as an intent. So I have tried : </p>
<pre><code>Fragment f = new UserFragment();
Bundle bundl = new Bundle();
bundl.putInt("pagenumbers", size);
f.setArguments(bundl);
lf.add(f);
</code></pre>
<p>Inside FirstFragment. But when UserFragment extracts its arguments under "pagenumbers" it is returning 0.
I then tried to gain access to the getCount() method that lives inside FragmentAdapter, however, I'm not sure how to go about this, given that I'm inside UserFragment when I need it.</p>
<p>What I'm trying to do maybe to help clarify, is I'm extracting "current page info" which I now have working thanks to an earlier post of mine and those whom helped. Now I want to see if "currentpage == size (//which is number of pages. Total views in the viewpager)". So in the onClick method you can see in UserFragment, if it's the last page, and the user hits the button to go to the next page. I want it to jump to another activity, where it manipulates all the SparseArray data that was collected from all the forms. (Which I need help on how to put this SparseArray data into an intent, I will probably make a new question with this ... as it's not very related). So if you could either assist me in getting my current attempts to work (how to do it properly) or just suggest an entirely new method I'm happy. As long as I can get it working!</p>
<p>Thank you very much for all your assistance, in advanced. Please help! </p>

vue.js: how to update state with object?
|
<p>I am a newcomer to vue.js, but I have some experience with React from before.</p>
<p>I have read the vue guidelines and I am trying to understand vue through the concepts from React.</p>
<p>I assume that the vue <code>data</code> is similar to the React <code>state</code>, since when it updates the app it will render the page again.</p>
<p>So I would like to do something like ... (the code is in React) </p>
<pre><code>this.setState(Object.assign({}, this.state, { key1: 'value1', key2 : 'value2'}))
</code></pre>
<p>But as far as I know, in vue:</p>
<pre><code>this.key1 = 'value1';
this.key2 = 'value2';
</code></pre>
<p>Is that correct? I guess vue will render twice since it is 2 statements.
How could I set multi values at once?</p>
<p>I have already tried ...</p>
<pre><code>// not working
this.$set(Object.assign({}, thisRef.data, { key1: 'value1', key2: 'value2' }))
// not working
this.data = { key1 : 'value1', key2: 'value2' };
</code></pre>
<p>In the second one, data has changed - I have printed value with <code>console.log(this)</code>- , but it does not render again.</p>
<p>FYI, the full code from the vue template is here. Code review and correction will be very welcomed.</p>
<pre><code><script>
export default {
layout: 'reactQuickly'
, data: function(){
return {
time: null
, init: null
}
}
, methods: {
startTimer: function(time){
clearInterval(this.init);
let thisRef = this;
let interval = setInterval(
function(){
console.log('2: Inside of interval', time)
let timeLeft = thisRef.time - 1;
if(timeLeft <= 0) clearInterval(interval);
thisRef.time = timeLeft;
// thisRef.$set(Object.assign({}, thisRef.data, { time: timeLeft }))
console.log('thisRef', thisRef, this);}
, 1000);
console.log('1: After interval');
// this.data = { time : time, init: interval };
this.time = time;
this.init = interval;
console.log('this.data', this.data);
// this.$set(Object.assign({}, this.data, { time : time, init: interval}));
}
}
}
</script>
</code></pre>
<p>============ Edition ===========</p>
<p>react <code>this.state</code> and vue <code>this.data</code> is not same, right?
To me, main confusion starts from that point.</p>
<p>In vue</p>
<pre><code>export default {
data : function() {
return {
foo : 'bar'
}
}
}
</code></pre>
<p>and </p>
<p>In react</p>
<pre><code>constructor() {
super()
this.state = {
foo : 'bar'
}
}
</code></pre>
<p>are completely different concept, right?</p>

Django - how to save my hashed password
|
<p>I'm trying to save my hashed password in my database, but It keeps saving my plaintext password</p>
<p><strong>Models:</strong></p>
<pre><code>class StudentRegistration(models.Model):
email = models.EmailField(max_length=50)
first_name = models.CharField(max_length=20)
last_name = models.CharField(max_length=20)
password = models.CharField(max_length=100, default="", null=False)
prom_code = models.CharField(max_length=8, default="", null=False)

("F","Female"),
)

self.prom_year = Myobj.prom_year
self.school = Myobj.school_name

print("Error")
</code></pre>
<p><strong>Views:</strong></p>
<pre><code>def register_user(request):

else:
form = MyRegistrationForm()
args['form'] = form #MyRegistrationForm()
return render(request, 'register/register.html', args)
</code></pre>
<p>I've printed the hashed result so I know it is hashing but not saving that. </p>
<p>Am I using the make_password wrong? or is there any better way to protect my passwords?</p>
<p>--------------------------<strong>UPDATE:(The Solution)</strong>----------------------------</p>
<p>Remember In settings.py:</p>
<pre><code>#The Hasher you are using
PASSWORD_HASHERS = (
'django.contrib.auth.hashers.MD5PasswordHasher',
)
</code></pre>
<p>Models.py:</p>
<pre><code>#Import and add the AbstractBaseUser in your model
class StudentRegistration(AbstractBaseUser, models.Model):
</code></pre>
<p>Views.py: </p>
<pre><code>if form.is_valid():
user = form.save(commit=False)
clearPassNoHash = form.cleaned_data['password']
varhash = make_password(clearPassNoHash, None, 'md5')
user.set_password(varhash)
user.save()

<p><strong><em>as per the suggestion in the post below (thx, joshmc), here is the AMQERR01.log</em></strong>
it appears to provide a clue... -now, the quest to determine how to I unblock the 'admin' user :-)</p>

AMQ9776: Channel was blocked by userid
EXPLANATION:
The inbound channel 'DEV.APP.SVRCONN' was blocked from address '172.17.0.1'
because the active values of the channel were mapped to a userid which should
be blocked. The active values of the channel were 'MCAUSER(admin)
CLNTUSER(admin)'.
ACTION:
Contact the systems administrator, who should examine the channel
authentication records to ensure that the correct settings have been
configured. The ALTER QMGR CHLAUTH switch is used to control whether channel
authentication records are used. The command DISPLAY CHLAUTH can be used to
query the channel authentication records.

Using primefaces p:tabView, the refresh of the tabs using p:ajax doesn't work fine. The first time refresh but the next times doesn't refresh

<p>I have a page with a tabView, with 3 tabs, each tab has a tree. The tree of the third tab (DEVICES CATEGORY/TYPE), depends on what I select in the tree of the second tab (CERTIFICATIONS SYSTEM/PROGRAM).

<pre><code><p:ajax event="tabChange" listener="#{profileMB.onTabChange}" />
</code></pre>
<p>When I select an element of the tree of the second tab and I change to the third tab, <strong>for the first time, it works OK</strong>, but when I <strong>return to the second tab</strong> and I <strong>mark differents nodes</strong> of the tree and I change to the third tab, <strong>the third tabs doesn't refresh</strong>.</p>
<p>The methods of the event it works OK, and generate the tree well.</p>
<pre><code>public void onTabChange(TabChangeEvent event) {

Sprite Rotation in Android using Canvas.DrawBitmap. I am close, what am I doing wrong?
|
<p>I have this sprite rotating algorithm (its poorly named and just used for testing). It is so close, sprites drawn with it do rotate. Everyframe I can add +5 degrees to it and see my nice little sprite rotate around. The problem is, the other stuff drawn to the canvas now flickers. If I don't do the rotation the regular drawn sprites work great. I think I am close but I just don't know what piece I am missing. Below is my two "Draw_Sprite" methods, one just draws the previously resource loaded bitmap to the canvas passed in. The other one, does some rotation the best I know how to rotate the sprite by so x many degrees..and then draw it. If I have a nice game loop that draws several objects, one type is the rotated kind. Then the non-rotated sprites flicker and yet the rotated sprite never does. Though if I draw the non-rotated sprites first, all is well, but then the Z-Ordering could be messed up (sprites on top of UI elements etc)... The method definitions:</p>
<pre><code> /*************************************************
* rotated sprite, ignore the whatever, its for ease of use and testing to have this argument list
* @param c canvas to draw on.
* @param whatever ignore
* @param rot degrees to rotate
* @return
*/
public int Draw_Sprite(Canvas c, int whatever, int rot) {
//rotating sprite
Rect src = new Rect(0, 0, width, height);
Rect dst = new Rect(x, y, x + width, y + height);
Matrix orig = c.getMatrix();
mMatrix = orig;
orig.setTranslate(0, 0);
orig.postRotate(rot, x+width/2, y+height/2);
c.setMatrix(orig);
c.drawBitmap(images[curr_frame], src, dst, null);
c.setMatrix(mMatrix); //set it back so all things afterwards are displayed correctly.
isScaled=false;
return 1;
}
/********************************************************
* draw a regular sprite to canvas c
* @param c
* @return
*/
public int Draw_Sprite(Canvas c) {
Rect src = new Rect(0, 0, width, height);
Rect dst = new Rect(x, y, x + width, y + height);
c.drawBitmap(images[curr_frame], src, dst, null);
isScaled=false;
return 1;
}
</code></pre>
<p>And now the usage:</p>
<pre><code>void onDraw(Canvas c)
{
canvas.drawRect( bgRect, bgPaint); //draw the background
//draw all game objects
// draw the normal items
for (GameEntity graphic : _graphics) {
graphic.toScreenCoords((int)player_x, (int)player_y);
if(graphic.getType().equals("planet")) //draw planets
graphic.Draw_Sprite(canvas); //before the rotation call draws fine
else
{
//rotate all space ships every frame so i see them spinning
//test rotation
mRot +=5;
if(mRot>=360)
mRot=0;
graphic.Draw_Sprite(canvas, 0, mRot); //yes function name will be better in future. this rotates spins draws fine
}
}
thePlayer.Draw_Sprite(canvas); //FLICKERS
drawUI(canvas);//all things here flickr
}
</code></pre>
<p>So it does do it, things after a call to a rotational draw are drawn correctly. But the problem is it flickrs. Now One could say I should just do all my non rotational stuff and save that last, but the zordering would be off.... suggestions as to how to tackle this issue of zordering or the flickering?</p>

How to re-render Formik values after updated it - React Native?
|
<p>I have a screen for update previously data "name, email, age, etc". at the first time I call a function that gets data from server name as <code>getProfileData()</code></p>
<p>after user write the new data I send a POST request for that "update Profile"</p>
<p>and it's a success, but after that, I want to re-render this form with new data, So i call the <code>getProfileData()</code> function to get new data but it's not working to re-render Input Values!
it's just still with previous data</p>
<p>I also try with <code>componentDidUpdate()</code> but sadly not re-render :)</p>
<p>So how can i solve it?</p>
<p>Code </p>
<pre><code>getProfileData = async () => {
let USER_TOKEN =
'....';
let AuthStr = `Bearer ${USER_TOKEN}`;
let response = await API.get('/profile', {

});
let {
data: {data},
} = response;
let password = '';
let password_confirmation = '';
let {name, email, avatar, age, gender, country_id} = data;
let initialValues = [];
initialValues.push({
name,
password,
password_confirmation,
email,
avatar,
age,

this.setState({initialValues: initialValues, loading: false}, () =>

};
updateProfile = async value => {
let USER_TOKEN =
'....';
let AuthStr = `Bearer ${USER_TOKEN}`;
const headers = {

Authorization: AuthStr,
};
let response = await API.post('/update_profile', value, {

});
let {
data: {data},
} = response;
alert(data);
this.getProfileData(); // called
};
componentDidMount() {
this.getCountryList();
this.getProfileData();
}
componentDidUpdate(prevProps, prevState) {
if (prevState.initialValues !== this.state.initialValues) {
console.log('componentDidUpdate', this.state.initialValues);
this.setState({initialValues: this.state.initialValues});

Angular2: rendering / reloading a component's template
|
<p>Ideally I would need to reload / rerender my component's template but if there is a better way to do this I will gladly implement it.</p>
<p><strong>Desired behavior:</strong></p>
<p>So, I have a component for a menu element. When <em>(in another component)</em> I click an IBO <em>(some sort of 'client', per say)</em> is clicked I need to <em>add</em> (I'm using <code>*ngIf</code>) a new option in the menu that would be <em>IBO Details</em> and a child list.</p>
<p><strong><code>IBOsNavigationElement</code> component (menu component):</strong></p>
<pre class="lang-js prettyprint-override"><code>@Component({
selector: '[ibos-navigation-element]',
template: `
<a href="#"><i class="fa fa-lg fa-fw fa-group"></i> <span
class="menu-item-parent">{{'IBOs' | i18n}}</span>
</a>
<ul>
<li routerLinkActive="active">
<a routerLink="/ibos/IBOsMain">{{'IBOs Main' | i18n}} {{id}}</a>
</li>
<li *ngIf="navigationList?.length > 0">
<a href="#">{{'IBO Details' | i18n}}</a>
<ul>
<li routerLinkActive="active" *ngFor="let navigatedIBO of navigationList">
<a href="#/ibos/IboDetails/{{navigatedIBO['id']}}">{{navigatedIBO['name']}}</a>
</li>
</ul>
</li>
</ul>
`
})
export class IBOsNavigationElement implements OnInit {
private navigationList = <any>[];
constructor(private navigationService: NavigationElementsService) {
this.navigationService.updateIBOsNavigation$.subscribe((navigationData) => {
this.navigationList.push(navigationData);
log.d('I received this Navigation Data:', JSON.stringify(this.navigationList));
}
);
}
ngOnInit() {
}
}
</code></pre>
<p>Initially, <code>navigationList</code> will be empty <code>[]</code>, because the user didn't click any IBO <em>(client)</em>, but as soon as an IBO is clicked the list will be populated and, therefore, I need the new option to appear in the menu.</p>
<p>With this code, when I click an IBO, the <code><li></code> element and it's children are created but: <strong>I only see the <code><li></code> element.</strong></p>
<p><strong>Issue:</strong></p>
<p>The menu option is generated but not proccessed by the layout styles. It needs to be initialized with all the elements in order to know how to display the menu options.</p>
<p><strong>I need to reload the template of that component in order to display correctly the menu.</strong></p>
<p><strong>NOTE:</strong></p>
<p>If I use the template without the <code>*ngIf</code>, works well but I would have from the first moment an <em>IBO Details</em> option that has no sense, because no IBO has been clicked when initialized.</p>
<pre class="lang-js prettyprint-override"><code>template: `
<a href="#"><i class="fa fa-lg fa-fw fa-group"></i> <span
class="menu-item-parent">{{'IBOs' | i18n}}</span>
</a>
<ul>
<li routerLinkActive="active">
<a routerLink="/ibos/IBOsMain">{{'IBOs Main' | i18n}} {{id}}</a>
</li>
<li>
<a href="#">{{'IBO Details' | i18n}}</a>
<ul>
<li routerLinkActive="active" *ngFor="let navigatedIBO of navigationList">
<a href="#/ibos/IboDetails/{{navigatedIBO['id']}}">{{navigatedIBO['name']}}</a>
</li>
</ul>
</li>
</ul>
`
</code></pre>
<p><strong>Desired Output:</strong></p>
<p>Before clicking anything (on init):</p>
<p><a href="https://i.stack.imgur.com/gAv2n.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/gAv2n.jpg" alt="enter image description here"></a></p>
<p>After I clicked an IBO <em>(client)</em>:</p>
<p><a href="https://i.stack.imgur.com/7xaBU.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/7xaBU.jpg" alt="enter image description here"></a></p>
<p><strong>Update 1:</strong></p>
<p>To clarify what I meant with: </p>
<blockquote>
<p>The menu option is generated but not proccessed by the layout styles</p>
</blockquote>
<p>If, my menu component is initialized without the <code>*ngIf</code>:</p>
<pre class="lang-js prettyprint-override"><code><li>
<a href="#">{{'IBO Details' | i18n}}</a>
<ul>
<li routerLinkActive="active" *ngFor="let navigatedIBO of navigationList">
<a href="#/ibos/IboDetails/{{navigatedIBO['id']}}">{{navigatedIBO['name']}}</a>
</li>
</ul>
</li>
</code></pre>
<p>Then the layout styles can generate the menu output <em>(see images)</em> according to this structure:</p>
<pre class="lang-js prettyprint-override"><code><li>
<a>
<ul>
<li *ngFor>
<a>
</li>
</ul>
</li>
</code></pre>
<p>And therefore add the <code>+</code> symbol and the submenu behavior, etc.</p>
<p>But, if it's initialized without all the elements (when <code>*ngIf</code> is <code>false</code> the <code><li></code> and it's children are not rendered so the layout does not take them into account to draw/create the menu) and these elements are added <strong>after</strong> the rendering, then they will exist in source code, but we won't be able to see them in the menu because:</p>
<ul>
<li>No <code>+</code> created</li>
<li>No submenu behavior</li>
</ul>

Django count on many-to-many
|
<p>I have the models:</p>
<pre><code>class Article(models.Model):
title = models.TextField(blank=True)
keywords = models.ManyToManyField(Keyword, null=True, blank=True)
class Keyword(models.Model):
keyword = models.CharField(max_length=355, blank=True)
</code></pre>
<p>I want to get a count of how many articles have each keyword. In essence I want to have a list of keywords where I can get each ones count to give it a relative weighting.</p>
<p>I have tried: </p>
<pre><code>keyword_list=Article.objects.all().annotate(key_count=Count('keywords__keyword'))
</code></pre>
<p>but </p>
<pre><code>keyword_list[0].key_count
</code></pre>
<p>just seems to give me the number of <em>different</em> keywords each article has? Is it somehow a reverse lookup?</p>
<p>Any help would be much appreciated.</p>
<p><strong>UPDATE</strong></p>
<p>So I got it working:</p>
<pre><code>def keyword_list(request):
MAX_WEIGHT = 5
keywords = Keyword.objects.order_by('keyword')
for keyword in keywords:
keyword.count = Article.objects.filter(keywords=keyword).count()
min_count = max_count = keywords[0].count
for keyword in keywords:
if keyword.count < min_count:
min_count = keyword.count
if max_count > keyword.count:
max_count = keyword.count
range = float(max_count - min_count)
if range == 0.0:
range = 1.0
for keyword in keywords:
keyword.weight = (
MAX_WEIGHT * (keyword.count - min_count) / range
)
return { 'keywords': keywords }
</code></pre>
<p>but the view results in a hideous number of queries. I have tried implementing the suggestions given here (thanks) but this is the only methid which seems to work at the moment. However, I must be doing something wrong as I now have 400+ queries!</p>
<p><strong>UPDATE</strong></p>
<p>Wooh! Finally got it working:</p>
<pre><code>def keyword_list(request):
MAX_WEIGHT = 5
keywords_with_article_counts = Keyword.objects.all().annotate(count=Count('keyword_set'))
# get keywords and count limit to top 20 by count
keywords = keywords_with_article_counts.values('keyword', 'count').order_by('-count')[:20]
min_count = max_count = keywords[0]['count']
for keyword in keywords:
if keyword['count'] < min_count:
min_count = keyword['count']
if max_count < keyword['count']:
max_count = keyword['count']
range = float(max_count - min_count)
if range == 0.0:
range = 1.0
for keyword in keywords:
keyword['weight'] = int(
MAX_WEIGHT * (keyword['count'] - min_count) / range
)
return { 'keywords': keywords}

Why is my scoped_session raising an AttributeError: 'Session' object has no attribute 'remove'
|
<p>I'm trying to set up a system that elegantly defers database operations to a seperate thread in order to avoid blocking during Twisted callbacks.</p>
<p>So far, here is my approach:</p>
<pre><code>from contextlib import contextmanager
from sqlalchemy import create_engine
from sqlalchemy.orm import scoped_session, sessionmaker
from twisted.internet.threads import deferToThread
_engine = create_engine(initialization_string)
Session = scoped_session(sessionmaker(bind=_engine))
@contextmanager
def transaction_context():
session = Session()
try:
yield session
session.commit()
except:
# No need to do session.rollback(). session.remove will do it.
raise
finally:
session.remove()
def threaded(fn):
@wraps(fn)
def wrapper(*args, **kwargs):
return deferToThread(fn, *args, **kwargs)
return wrapper
</code></pre>
<p>This should allow me to wrap a function with the <code>threaded</code> decorator and then use the <code>transaction_context</code> context manager in said function's body. Below is an example:</p>
<pre><code>from __future__ import print_function
from my_lib.orm import User, transaction_context, threaded
from twisted.internet import reactor
@threaded

Bootstrap SASS variable override challenge
|
<p><strong>EDIT:</strong> This question was marked as a duplicate of <a href="https://stackoverflow.com/questions/17089717/how-to-overwrite-scss-variables-when-compiling-to-css">this one</a>, but see the addendum near the end of this answer to see what that question doesn't ask, and what the answer doesn't answer.</p>
<p>I'm working on a web app that uses Bootstrap 3. I have a basic 3-layer override architecture, where 1) Bootstrap's _variables.scss contains the core variables, 2) _app-variables.scss contains the base app variables that override Bootstrap's _variables.scss, and 3) _client-variables.scss contains client-specific customizations that override _app-variables.scss. Either #2 or #3 (or both) can be blank files. So here's the override order:</p>
<pre><code>_variables.scss // Bootstrap's core
_app-variables.scss // App base
_client-variables.scss // Client-specific
</code></pre>
<p>Simple enough in theory, but a problem arises because of what I'll call "variable dependencies" -- where variables are defined as other variables. For example:</p>
<pre><code>$brand: blue;
$text: $brand;
</code></pre>
<p>Now, let's say the above variables are defined in _variables.scss. Then let's say in _app-variables.scss, I override only the $brand variable to make it red: <code>$brand: red</code>. Since SASS interprets the code line by line sequentially, it will first set $brand to blue, then it will set $text to blue (because $brand is blue at that point), and finally it will set $brand to red. So the end result is that changing $brand afterwards does not affect any variables that were based on the old value of $brand:</p>
<pre><code>_variables.scss
---------------------
$brand: blue;
$text: $brand; // $text = blue
.
.
.
_app-variables.scss
---------------------
$brand: red; // this does not affect $text, b/c $text was already set to blue above.
</code></pre>
<p>But obviously that's not what I want - I want my change of $brand to affect everything that depends on it. In order to properly override variables, I'm currently just making a full copy of _variables.scss into _app-variables.scss, and then making modifications within _app-variables from that point. And similarly I'm making a full copy of _app-variables.scss into _client-variables.scss and then making modifications within _client-variables.scss at that point. Obviously this is less than ideal (understatement) from a maintenance point of view - everytime I make a modification to _variables.scss (in the case of a Bootstrap upgrade) or _app-variables.scss, I have to manual trickle the changes down the file override stack. And plus I'm having to redeclare a ton of variables that I may not even be overriding.</p>
<p>I found out that LESS has what they call "lazy loading" (<a href="http://lesscss.org/features/#variables-feature-lazy-loading" rel="noreferrer">http://lesscss.org/features/#variables-feature-lazy-loading</a>), where the last definition of a variable is used everywhere, even before the last definition. I believe this would solve my problem. But does anyone know a proper variable-override solution using SASS?</p>
<p><strong>ADDENDUM:</strong><br>
Here's one technique I've already thought through: include the files in reverse order, using <code>!default</code> for all variables (this technique was also suggested in the answer to <a href="https://stackoverflow.com/questions/17089717/how-to-overwrite-scss-variables-when-compiling-to-css">this question</a>). So here's how this would play out:</p>
<pre><code>_app-variables.scss
---------------------
$brand: red !default; // $brand is set to red here, overriding _variables.scss's blue.
.
.
.
_variables.scss
---------------------
$brand: blue !default; // brand already set in _app-variables.scss, so not overridden here.
$text: $brand !default; // $text = red (desired behavior)
</code></pre>
<p>So that solution is <strong><em>almost</em></strong> perfect. <strong><em>However</em></strong>, now in my override files, I don't have access to variables defined in Bootstrap's _variables.scss, which I would need if I wanted to define my variable overrides (or my own additional custom variables) using other Bootstrap variables. For example, I might want to do: <code>$custom-var: $grid-gutter-width / 2;</code></p>

Apache Rewrite - Redirect Wildcard Subdomain and Handling Internal URL shortener
|
<p>I have problem in redirecting wild-card sub-domain and handing internal URL shortener.</p>
<p>Let's say I have an internal URL shortener in my app</p>
<pre><code>example.com/b/ABCDE
</code></pre>
<p>that will translate</p>
<pre><code>example.com/book/12345678-the-book-name
</code></pre>
<p>the script referred by <code>/b/</code> (I use PHP framework that could handle URL rule) will translate short ID <code>ABCDE</code> to the book real ID <code>12345678</code> (and the title "The Book Name") then redirect it the book's permanent URL <code>example.com/book/12345678-the-book-name</code></p>
<p>so then every time I spread a link about a book in websites like bulletin boards, micro-blogging sites, or physical media like posters or business cards, I use the short link (the <code>example.com/b/ABCDE</code>) instead of the permanent link (<code>example.com/book/12345678-the-book-name</code>).</p>
<p>next, I need to redirect all wild-card sub-domain to the main domain (<code>www.example.com</code>) while maintaining the request URI, e.g.</p>
<pre><code>http://random.example.com/book/11111111-some-book -> http://www.example.com/book/11111111-some-book
http://123456.example.com/book/22222222-another-book -> http://www.example.com/book/22222222-another-book
http://abcdefg.example.com/book/33333333-another-book-again -> http://www.example.com/book/33333333-another-book-again
</code></pre>
<p>by adding the rule below after all the rules I used</p>
<pre><code><VirtualHost *:80>
ServerName example.com
ServerAlias *.example.com
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.example.com [NC]
RewriteRule ^/(.*)$ http://www.example.com/$1 [R=301]
</VirtualHost>
</code></pre>
<p>Consequently the url with example.com domain and without prefix like below</p>
<pre><code>http://example.com/book/11111111-some-book
</code></pre>
<p>will translate to</p>
<pre><code>http://www.example.com/book/11111111-some-book
</code></pre>
<p>And, another consequence is that if the internal URL shortener use plain domain without the prefix, it will take two redirection to resolve. For example, </p>
<pre><code>http://example.com/b/ABCDE
</code></pre>
<p>will first be redirected to </p>
<pre><code>http://www.example.com/b/ABCDE
</code></pre>
<p>which then be redirected to </p>
<pre><code>http://www.example.com/book/12345678-the-book-name
</code></pre>
<p>Actually, I don't mind with the two-times redirection. But my SEO consultant said that the two-times redirection is bad for my site's SEO. (which I still don't know why)</p>
<p>So I tried change the last rule to below</p>
<pre><code><VirtualHost *:80>
ServerName example.com
ServerAlias *.example.com
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example.com [NC]
RewriteCond %{REQUEST_URI} ^/b/(.*)$
RewriteRule . index.php [L]
RewriteCond %{HTTP_HOST} !^www.example.com [NC]
RewriteRule ^/(.*)$ http://www.example.com/$1 [R=301]
</VirtualHost>
</code></pre>
<p>I'm not very good at configuring Apache, but when I simulate above rule in <a href="http://htaccess.madewithlove.be/" rel="nofollow">http://htaccess.madewithlove.be/</a>, it works. But when I applied it to my server, it gave me <strong>400 Bad Request</strong> for the <code>example.com/p/ABCDE</code>.</p>
<p>So, my questions are</p>
<ol>
<li>Is my SEO consultant right about his argument? Is there any explanation that can back him up or is there a counter-argument?</li>
<li>Why the server gave <strong>400 Bad Request</strong>?</li>
<li>How to fix the redirection? I want to maintain the short URL (<code>example.com/b/ABCDE</code> without <code>www</code> prefix) but still in one redirection.</li>
</ol>

Android Eclipse failing to debug
|
<p>Debugging of my app is now suddenly broken. It has been fine up to now and I even reloaded a known good version of my entire code and it still fails to debug or even run. When I hit debug or run the app starts up and right when it is about to display the app, it crashes (before even entering the main view). I have a break point on the first line of code and it never even reaches it. It just goes to Source not found - The source attachment does not contains the source for the file DexFile.class.....
I am 100% certain all the code I have loaded is working, as it is a saved backup which was saved when last working.</p>
<p>Also, what is odd is that if I unplug the cable at this point, the app loads normally and works fine. So this is definitely a debugging issue. It is getting stuck somewhere at boot. I have restarted my computer and phone several times to no avail.</p>

Sending image over sockets (ONLY) in Python, image can not be open
|
<p>I want to upload the image from client to server using ONLY sockets in Python. I designed a very simple protocol flow of how I would like to do this:</p>
<pre><code>CLIENT SERVER
SIZE 512 (send image size)
---------------------------------->
GOT SIZE
<----------------------------------
send image itself
---------------------------------->
GOT IMAGE
<----------------------------------
BYE BYE
---------------------------------->
server closes socket
</code></pre>
<p>Here's my client code:</p>
<pre><code>#!/usr/bin/env python
import random
import socket, select
from time import gmtime, strftime
from random import randint
image = "tux.png"
HOST = '127.0.0.1'
PORT = 6666
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = (HOST, PORT)
sock.connect(server_address)
try:
# open image
myfile = open(image, 'rb')
bytes = myfile.read()
size = len(bytes)
# send image size to server
sock.sendall("SIZE %s" % size)
answer = sock.recv(4096)
print 'answer = %s' % answer
# send image to server
if answer == 'GOT SIZE':
sock.sendall(bytes)
# check what server send
answer = sock.recv(4096)
print 'answer = %s' % answer
if answer == 'GOT IMAGE' :
sock.sendall("BYE BYE ")
print 'Image successfully send to server'
myfile.close()
finally:
sock.close()
</code></pre>
<p>And my server, which receives images from clients:</p>
<pre><code>#!/usr/bin/env python
import random
import socket, select
from time import gmtime, strftime
from random import randint
imgcounter = 1
basename = "image%s.png"
HOST = '127.0.0.1'
PORT = 6666
connected_clients_sockets = []
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
server_socket.bind((HOST, PORT))
server_socket.listen(10)
connected_clients_sockets.append(server_socket)
while True:
read_sockets, write_sockets, error_sockets = select.select(connected_clients_sockets, [], [])
for sock in read_sockets:
if sock == server_socket:
sockfd, client_address = server_socket.accept()
connected_clients_sockets.append(sockfd)
else:
try:
data = sock.recv(4096)
txt = str(data)
if txt.startswith('SIZE'):
tmp = txt.split()
size = int(tmp[1])
print 'got size'
sock.send("GOT SIZE")
elif txt.startswith('BYE'):
sock.shutdown()
elif data:
myfile = open(basename % imgcounter, 'wb')
data = sock.recv(40960000)
if not data:
myfile.close()
break
myfile.write(data)
myfile.close()
sock.send("GOT IMAGE")
sock.shutdown()
except:
sock.close()
connected_clients_sockets.remove(sock)
continue
imgcounter += 1
server_socket.close()
</code></pre>
<p>For the example image:</p>
<p><a href="https://i.stack.imgur.com/CNyA4.png" rel="noreferrer"><img src="https://i.stack.imgur.com/CNyA4.png" alt="enter image description here"></a></p>
<p>The client prints out messages, that suggest, that it send the image to server successfully:</p>
<pre><code>answer = GOT SIZE
answer = GOT IMAGE
Image successfully send to server
</code></pre>
<p>The image is created at server's side, but I can not open it. And yes, I tried different images. With no success. I can't open them at server's side, even though they are available there. </p>
<p>Thanks to @BorrajaX, I managed to make it work! Thanks! :)</p>

Revised Simplex Method - Matlab Script
|
<p>I've been asked to write down a Matlab program in order to solve LPs using the <strong>Revised Simplex Method</strong>. </p>
<p>The code I wrote runs without problems with input data although I've realised it doesn't solve the problem properly, as it does not update the inverse of the basis B (the real core idea of the abovementioned method).</p>
<p>The problem is only related to a part of the code, the one in the bottom of the script aiming at:</p>
<p><strong>Computing the new inverse basis B^-1 by performing elementary row operations on [B^-1 u] (pivot row index is l_out). The vector u is transformed into a unit vector with u(l_out) = 1 and u(i) = 0 for other i.</strong></p>
<p>Here's the code I wrote:</p>
<pre><code> %% Implementation of the revised Simplex. Solves a linear
% programming problem of the form
%
% min c'*x
% s.t. Ax = b
% x >= 0
%

How to return an ArrayList <Integer>?
|
<p>I am working on a question from an assignment. It is called the 3n+1 problem. The task is to get an integer from user (not 1 or negative number) and based on the number input (n), if it is even - divide by 2, and if it is negative - multiple n * 3 + 1.</p>
<p>The method I MUST use is as follows:</p>
<pre><code>public static ArrayList<Integer> getHailstoneSequence(int n) {
</code></pre>
<p>^ this part is mandatory for my assignment, so it is necessary for me to work with an ArrayList of Integers. </p>
<p>I am struggling to make my program work. I can't figure out if I should store the input in the main method OR in my definition class. I also am not sure how to have the loop execute for even numbers in the main method without the redundancy of already having it stated in the definition class ( where my getHailstoneSequence() method is located).</p>
<p>Here is the code I have: <strong>(DEFINITION CLASS)</strong></p>
<pre><code>package question7;
import java.util.ArrayList;
public class HailstoneSequence {
// Method for computing the Hailstone Sequence:
public static ArrayList<Integer> getHailstoneSequence(int n) {
ArrayList<Integer> hailstoneSequence = new ArrayList<Integer>();
if (n % 2 == 0) {
n = n / 2;
hailstoneSequence.add(n);
}
else {
n = (n * 3) + 1;
hailstoneSequence.add(n);
}
return hailstoneSequence;
}
}
</code></pre>
<p>I am unsure how to include the method I created above into the main method for printing. I want the output to look like this (example):</p>
<p>5 is odd, so we make 3N+1: 16
16 is even, so we take half: 8
8 is even, so we take half: 4
4 is even, so we take half: 2
2 is even, so we take half: 1</p>
<p>And have the program stop whe n = 1</p>
<p>Here is what I have in my <strong>main method</strong> to date:</p>
<pre><code>package question7;
import java.util.ArrayList;
import java.util.Scanner;
public class HailstoneSequenceTest {
public static void main(String[] args) {
Scanner hailstone = new Scanner(System.in);
System.out.println("To begin, please enter a positive integer that is not 1:");
int n = hailstone.nextInt();
ArrayList<Integer> list = HailstoneSequence.getHailstoneSequence(n);
for (int sequence : list) {
try {
if (n > 1) {
System.out.println("Great choice! Let's begin!");
System.out.println();
while (n % 2 == 0) {
System.out.println(n +
" is even, so we take half: " +
HailstoneSequence.getHailstoneSequence(n));
list.add(n);
if (n == 1) break;
while (n % 2 != 0) {
System.out.println(n +
" is odd, so I make 3n+1: " +
HailstoneSequence.getHailstoneSequence(n));
list.add(n);
if (n == 1) break;
}
// while (n == 1) {
// System.out.println(sequence);
// break;
}
}
}
catch (Exception error) {
while (n <= 1) {
System.out
.println("You did not enter a valid positive, greater than 1 integer. Please try again: ");
System.out.println();
n = hailstone.nextInt();
}
// End of HailstoneSequenceTest class
hailstone.close();
}
}
}
}
// }
</code></pre>
<p>Does anyone have any idea where I am going wrong? I know my code is probably wrong if multiple ways, I am just not sure where to start.</p>
<p>Do I need a for loop to hold the characteristics and increment ect.. ?</p>
<p>When I try to do this the way I know, it says I must return a ArrayList not an Int .</p>
<p>Please advise. </p>

Using Tables in RTF
|
<p>I need to create a table in an RTF file. However I am not familiar with RΤF. Here is an example of a text file that these RTF files are supposed to replace:</p>

Receipt of payment on account
from Customer, Check No. 5678
. . .
</code></pre>
<p>The table is supposed to have borders, but I don't know how to do this either. Some cells have to have special borders on the bottom as in this file:</p>

iPad Safari IOS 5 window.close() closing wrong window
|
<p>We have an iPad application that's working on our older iPads.</p>
<p>We open external links using
var x = window.open(url)</p>
<p>at the end of the day, when the user closes this part of the app, we go through all the windows it opened and do x.close() for each one and everything is okie dokie.</p>
<p>Testing on the new iPad with IOS 5 and the lovely tabs,
opening the new windows (although now they open as tabs) is fine, but doing x.close() doesn't seem to necessarily close x, it may close window y or z. Doing x.focus() or y.focus() works just fine, the correct tab comes into focus, but close seems to just pick whatever tab it wants.</p>
<p>Is this a bug or am I doing something wrong? Example program:</p>
<pre><code><html>
<head></head>
<body>
<script>
//The openWindow array will hold the handles of all open child windows
var openWindow = new Array();
var win1;
var win2;
//Track open adds the new child window handle to the array.
function trackOpen(winName) {
openWindow[openWindow.length]=winName;
}
//loop over all known child windows and try to close them. No error is
//thrown if a child window(s) was already closed.
function closeWindows() {
var openCount = openWindow.length;
for(r=openCount-1;r>=0;r--) {
openWindow[r].close();
}
}
//Open a new child window and add it to the tracker.
function open1() {
win1 = window.open("http://www.yahoo.com");
trackOpen(win1);
}
//Open a different child window and add it to the tracker.
function open2() {
win2 = window.open("http://www.google.com");
trackOpen(win2);
}
//Open whatever the user enters and add it to the tracker
function open3() {
var newURL = document.getElementById("url").value;
var win3= window.open(newURL);
trackOpen(win3);
}
</script>
<input type="button" value="Open 1" onclick="open1()">
<input type="button" value="Open 2" onclick="open2()">
<input type="button" value="Focus 1" onclick="win1.focus()">
<input type="button" value="Focus 2" onclick="win2.focus()">
<input type="button" value="Close 1" onclick="win1.close()">
<input type="button" value="Close 2" onclick="win2.close()">

iphone app - how to get the current location only once and store that to be used in another function?
|
<p>I've been working on this for the past 2 weeks - i have an app that shows a legible route on a map that goes from a start point to a destination point. the destination point is the users address (as defined/entered by the user in the settings menu we have set up) and if i hard code the start point, the map, route and application all work fine. once i try to implement anything that involves using the cllocation or cllocationmanager, it crashes and gives me a thread error (there are 3). </p>

<p>I'd basically like to ask if anyone can help shed some light on how I might go about getting the users current location coordinates and storing them as the start.latitude and start.longitude values so the route shows a pathway from the users current location to their destination. the route is not supposed to update itself as the user moves, I would just like to have an annotation/placemark on the users current location and destination (as i do have) and then the blue point (aka the user) will be able to see themselves move along the route they are to take. I've tried all the suggestions on here - and some havent worked at all, some worked only once and then after that it failed to work again (even after resetting the simulator content!). some links are relevant but very outdated so the methods there don't work.</p>
<p>And here i was thinking getting the users current location coordinates would be the easier task of this function!</p>

How to make dynamic content display across a grid using Django with Bootstrap?
|
<p>I'm working on a Django project with a homepage similar to StackOverflow's: it displays snippets of incoming user-generated content in a single main column. However, I'd like those content snippets to display across rows of 3 filling up the homepage (think [Pinterest pinboard page][2] or a grid layout blog).</p>
<p>I'm using Bootstrap's grid system, but realized I don't know the right combination of Python/Django template magic + Bootstrap to get that incoming content to populate across a grid. Can someone spell this out for me?</p>
<p>I want...</p>
<pre><code> {% for question in questions.paginator.page %}
{% question_list_item question %}
{% endfor %}
</code></pre>
<p>...to have the repeating effect of</p>
<pre><code><div class="container">
<div class="row clearfix">
<div class="col-md-4">
item 1
</div>
<div class="col-md-4">
item 2
</div>
<div class="col-md-4">
item 3
</div>
</div>
<div class="row clearfix">
<div class="col-md-4">
item 1
</div>
<div class="col-md-4">
item 2
</div>
<div class="col-md-4">
item 3
</div>
</div>
</div>
</code></pre>
<p><strong>Update:</strong> I was able to get this working (with a little column-count variation for responsiveness) using the following, but I'm a beginner so please let me know if there's a better solution.</p>
<pre><code> <div class="row">
{% for question in questions.paginator.page %}
<div class="col-lg-3 col-sm-6 col-xs-12">
{% question_list_item question %}
</div>
{% if forloop.counter|divisibleby:4 %}
</div>
<div class="row">
{% endif %}
{% endfor %}
</div>
</code></pre>
<p>Thank you!</p>

How to create a custom top navigation bar in React Native
|
<p>Hi i am building an app in React Native and I want to have a customized tabbar. I have tried it with React navigation but I can't figure out how to style the way I want...</p>
<p>This is what I want it to look like eventually:</p>
<p><a href="https://i.stack.imgur.com/YsV0G.png" rel="noreferrer">The information page</a></p>
<p><a href="https://i.stack.imgur.com/cKW9g.png" rel="noreferrer">The photos page</a></p>
<p>With react navigation i'm able to swipe the screen and go to the other page. So that is really nice usability which I'd like to keep (if that's possible ofcourse)</p>
<p>I have tried with passing a custom component in the navigator, but I couldn't get that to work. So when clean and native it looks like this right now:</p>
<pre><code>const ProfileTabScreen = ({ navigation }) => {
return (
<ProfileTabNavigator.Navigator>
<ProfileTabNavigator.Screen name="Info" component={ProfileInfoScreen} />
<ProfileTabNavigator.Screen name="Photos" component={ProfilePhotosScreen} />
</ProfileTabNavigator.Navigator>
);
};
</code></pre>
<p>The ProfileInfo- and ProfilePhotoScreen components are right now just empty views through which i can navigate with the top navigation.</p>
<h2>EDIT</h2>
<p>Thanks @Hikaru Watanabe, I have looked into createMaterialTopTabNavigator and managed to get it looking like the picture below. It works really well, the only thing I'm worries about is the white space on the sides I created because they are made with percentages (width: 45%, left: 2.5%). So on bigger screens it might look a bit different. This is not optimal, but I couldn't figure out how else to make it. This was the only thing that seemed to work and look the same on the iPhone and Android I test on.</p>
<p><a href="https://i.stack.imgur.com/zogQO.png" rel="noreferrer"><img src="https://i.stack.imgur.com/zogQO.png" alt="enter image description here" /></a></p>
<p>The code to get it done:</p>
<pre><code>const ProfileTabScreen = () => {
return (
<ProfileTabNavigator.Navigator tabBarOptions={{
activeTintColor: Colors.COLOR_WHITE,
labelStyle: {
textTransform: "uppercase",
},
inactiveTintColor: Colors.COLOR_SUPER_DARK_GREY,
indicatorStyle: {
height: null,
top: '10%',
bottom: '10%',
width: '45%',
left: '2.5%',
borderRadius: 100,
backgroundColor: Colors.PRIMARY_TWO,
},
style: {
alignSelf: "center",
width: '50%',
borderRadius: 100,
borderColor: "blue",
backgroundColor: "white",
elevation: 5, // shadow on Android
shadowOpacity: .10, // shadow on iOS,
shadowRadius: 4, // shadow blur on iOS
},
tabStyle: {
borderRadius: 100,
},
}}
swipeEnabled={true}>
<ProfileTabNavigator.Screen name="Info" component={ProfileInfoScreen} />
<ProfileTabNavigator.Screen name="Photos" component={ProfilePhotosScreen} />
</ProfileTabNavigator.Navigator>
);
};

How to expose property of QObject pointer to QML
|
<p>I am giving very brief (and partial) description of my class to show my problem. Basically I have setup two properties.</p>
<pre><code>class Fruit : public QObject
{
Q_OBJECT
....
public:
Q_PROPERTY( int price READ getPrice NOTIFY priceChanged)
Q_PROPERTY(Fruit * fruit READ fruit WRITE setFruit NOTIFY fruitChanged)
}
</code></pre>
<p>In my QML if I access the <code>price</code> property it works well and good. But if I access the <code>fruit</code> property which obviously returns <code>Fruit</code> and then try to use its <code>price</code> property, that doesn't work. Is this not supposed to work this way?</p>
<pre><code>Text {
id: myText
anchors.centerIn: parent
text: basket.price // shows correctly
//text: basket.fruit.price // doesn't show
}
</code></pre>
<p>The 2nd one returns <code>Fruit</code> which also is a property and it has <code>price</code> property but it doesn't seem to access that property? Should this work?</p>
<p><strong>Updated</strong> </p>
<p>I am including my source code. I created a new demo with <code>HardwareComponent</code>, it just makes more sense this way. I tried to make it work based on answer I received but no luck.</p>
<p><code>HardwareComponent</code> class is the base class for <code>Computer</code> and <code>CPU</code>.</p>
<h3>main.cpp</h3>
<pre><code>#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QQmlContext>
class HardwareComponent : public QObject
{
Q_OBJECT
public:
HardwareComponent() : m_price(0) {}
virtual int price() = 0;
virtual Q_INVOKABLE void add(HardwareComponent * item) { m_CPU = item; }
HardwareComponent * getCPU() const { return m_CPU; }
Q_SLOT virtual void setPrice(int arg)
{
if (m_price == arg) return;
m_price = arg;
emit priceChanged(arg);
}
Q_SIGNAL void priceChanged(int arg);
protected:
Q_PROPERTY(HardwareComponent * cpu READ getCPU);
Q_PROPERTY(int price READ price WRITE setPrice NOTIFY priceChanged)
HardwareComponent * m_CPU;
int m_price;
};
class Computer : public HardwareComponent
{
Q_OBJECT
public:
Computer() { m_price = 500; }
int price() { return m_price; }
void setprice(int arg) { m_price = arg; }
};
class CPU : public HardwareComponent
{
Q_OBJECT
public:
CPU() { m_price = 100; }
int price() { return m_price; }
void setprice(int arg) { m_price = arg; }
};
int main(int argc, char *argv[])
{
HardwareComponent * computer = new Computer;
CPU * cpu = new CPU;
computer->add( cpu );
QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
engine.rootContext()->setContextProperty("computer", computer);
return app.exec();
}
#include "main.moc"
</code></pre>
<h3>main.qml</h3>
<pre><code>import QtQuick 2.3
import QtQuick.Window 2.2
Window {
visible: true
width: 360
height: 360
Text {
anchors.centerIn: parent
text: computer.price // works
//text: computer.cpu.price // doesn't work, doesn't show any value
}
}
</code></pre>
<p>This is the complete source code for all my project files.</p>
<p>When I run it I get this output:</p>
<blockquote>
<p>Starting C:\Users\User\Documents\My Qt
Projects\build-hardware-Desktop_Qt_5_4_0_MSVC2010_OpenGL_32bit-Debug\debug\hardware.exe...
QML debugging is enabled. Only use this in a safe environment.
qrc:/MainForm.ui.qml:20: ReferenceError: computer is not defined</p>
</blockquote>
<p>Even though it gives a warning at line 20 (computer.price) line, it still works and shows the price of computer (=500). If change it <code>computer.cpu.price</code>, the same warning is reported but the price no longer shows - it doesn't seem to work.</p>
<p>The problem is since price is a virtual property, it works! but if I use this property on another hardware component inside the computer component, it doesn't work! The code/answer posted by Mido gives me hope there could be a solution to this, it looks quite close! I hope I can make this work.</p>

How to submit a form using JS, Node, Mongo, and Express?
|
<p>I am a beginner programmer. I am wondering how to submit a form, composed of JQuery date picker and radio buttons, using a button. I want to submit the form to a Mongo Database called <code>test</code>. In my <code>home.html</code> file I call the different stylesheets and javascript files I need. Then I set up an input field in the <code>home.html</code> and a button beneath the form to submit:</p>
<pre><code><!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<title>Home</title>
<!-- Local CSS and JS -->
<script src="/javascripts/home.js"></script>
<!-- Materialize: Compiled and minified CSS -->
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/materialize/0.97.0/css/materialize.min.css">
<!-- Materialize: Compiled and minified JavaScript -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/materialize/0.97.0/js/materialize.min.js"></script>
</head>
<body>
<!-- Input field I want to submit -->
<form method="post" action="/submit">
<input id="test1" type="radio"><label for="test1">Test</label>
<input id="test2" type="radio"><label for="test2">Test 2</label>
<input id="test3" type="radio"><label for="test3">Test 3</label>
</form>
<!-- Button I want to use to submit -->
<button type="submit" class="btn waves-effect waves-light" name="action">Sumbit</button>
</div>
</body>
</html>
</code></pre>
<p>Right now, I am loading this file by typing in localhost:3000/home.html. I want to use my <code>index.js</code> file to write the post method for submitting the data to my DB called <code>test</code>. After doing some research, I found that I'll need something to start my <code>index.js</code> like:</p>
<pre><code>var express = require('express');
var router = express.Router();
//TALKING TO THE DB?
var MongoClient = require('mongodb').MongoClient;
var assert = require('assert')
var ObjectId = require('mongodb').ObjectID;
var url = 'mongodb://localhost:27017/test';
var bodyParser = require('body-parser');
/*something would follow like?:
router.get('/submit', function(req, res) {
var db = req.test;
});*/
</code></pre>
<p>For reference, I'm using the express skeleton so my <code>app.js</code> looks like:</p>
<pre><code>var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
// Database
var mongo = require('mongodb');
var monk = require('monk');
//DB TEST
var db = monk('localhost:27017/test');
var routes = require('./routes/index');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
// uncomment after placing your favicon in /public
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
// error handlers
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
module.exports = app;
</code></pre>
<p>However, I am confused as to how to set up routes that grabs the data from my input fields (using the submit button). Then I want to use a post method to write that information to my <code>test</code> database. Any help would be greatly appreciated! Thank you!</p>

Create a count up timer in java (seconds and milliseconds only)
|
<p>I'm doing a <strong>count up timer in java</strong>. I found the following example: <a href="https://stackoverflow.com/questions/5745745/creating-a-count-up-timer-to-break-in-java">Creating a Count Up timer to Break in java</a>, and that's working fine. But I want to show the time in the <strong>format "mm:ss:SSS"</strong>, because I want to measure really small time responses. So, when it reaches the 1000 msec, it is 1 second.</p>
<p>I made some changes, but I can't present the time in the pretended format. The numbers start to appear were the seconds should be, and not in the milliseconds.</p>
<p>If you have a better example that the one that I'm following, it's fine.</p>
<p><strong>Edit:</strong> It is better, but it is not working fine yet. It is counting too slow (1 minute here correspond to 2 real minutes). My code is here:</p>
<pre><code>public class Counter extends JFrame {
private static final String stop = "Stop";
private static final String start = "Start";
private final ClockListener clock = new ClockListener();
private final Timer timer = new Timer(1, clock);
private final JTextField tf = new JTextField(9);
public Counter()
{
timer.setInitialDelay(0);
JPanel panel = new JPanel();
tf.setHorizontalAlignment(JTextField.RIGHT);
tf.setEditable(false);
panel.add(tf);
final JToggleButton b = new JToggleButton(start);
b.addItemListener(new ItemListener()
{
@Override
public void itemStateChanged(ItemEvent e)
{
if (b.isSelected())
{
timer.start();
b.setText(stop);
}
else
{
timer.stop();
b.setText(start);
}
}
});
panel.add(b);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.add(panel);
this.setTitle("Timer");
this.pack();
this.setLocationRelativeTo(null);
this.setVisible(true);
}
private class ClockListener implements ActionListener
{
private int minutes;
private int seconds;
private int milliseconds;
@Override
public void actionPerformed(ActionEvent e)
{
SimpleDateFormat date = new SimpleDateFormat("mm.ss.SSS");
if (milliseconds == 1000)
{
milliseconds = 000;
seconds++;
}
if (seconds == 60) {
seconds = 00;
minutes++;
}
tf.setText(String.valueOf(minutes + ":" + seconds + ":" + milliseconds));
milliseconds++;
}
}
public static void main(String[] args)
{
EventQueue.invokeLater(new Runnable()
{
@Override
public void run() {
Counter clock = new Counter();
clock.start();
}
});
}
}

Android RecyclerView addition & removal of items
|
<p>I have a RecyclerView with an TextView text box and a cross button ImageView. I have a button outside of the recyclerview that makes the cross button ImageView visible / gone.</p>
<p>I'm looking to remove an item from the recylerview, when that items cross button ImageView is pressed.</p>
<p>My adapter:</p>
<pre><code>public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> implements View.OnClickListener, View.OnLongClickListener {
private ArrayList<String> mDataset;
private static Context sContext;
public MyAdapter(Context context, ArrayList<String> myDataset) {
mDataset = myDataset;
sContext = context;
}
@Override
public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.my_text_view, parent, false);
ViewHolder holder = new ViewHolder(v);
holder.mNameTextView.setOnClickListener(MyAdapter.this);
holder.mNameTextView.setOnLongClickListener(MyAdapter.this);
holder.mNameTextView.setTag(holder);
return holder;
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.mNameTextView.setText(mDataset.get(position));
}
@Override
public int getItemCount() {
return mDataset.size();
}
@Override
public void onClick(View view) {
ViewHolder holder = (ViewHolder) view.getTag();
if (view.getId() == holder.mNameTextView.getId()) {
Toast.makeText(sContext, holder.mNameTextView.getText(), Toast.LENGTH_SHORT).show();
}
}
@Override
public boolean onLongClick(View view) {
ViewHolder holder = (ViewHolder) view.getTag();
if (view.getId() == holder.mNameTextView.getId()) {
mDataset.remove(holder.getPosition());
notifyDataSetChanged();
Toast.makeText(sContext, "Item " + holder.mNameTextView.getText() + " has been removed from list",
Toast.LENGTH_SHORT).show();
}
return false;
}
public static class ViewHolder extends RecyclerView.ViewHolder {
public TextView mNumberRowTextView;
public TextView mNameTextView;
public ViewHolder(View v) {
super(v);
mNameTextView = (TextView) v.findViewById(R.id.nameTextView);
}
}
}
</code></pre>
<p>My layout is:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center_vertical"
android:id="@+id/layout">
<TextView
android:id="@+id/nameTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="18sp"
android:padding="5dp"
android:background="@drawable/greyline"/>
<ImageView
android:id="@+id/crossButton"
android:layout_width="16dp"
android:layout_height="16dp"
android:visibility="gone"
android:layout_marginLeft="50dp"
android:src="@drawable/cross" />
</LinearLayout>
</code></pre>
<p>How can I get something like an onClick working for my crossButton ImageView? Is there a better way? Maybe changing the whole item onclick into a remove the item? The recyclerview shows a list of locations that need to be edited. Any technical advice or comments / suggestions on best implementation would be hugely appreciated.</p>

How to implement single search form in yii2
|
<p>Yii2 has a <code>searchModel</code> to search each field in the <code>GridView</code>. Is it possible to just create a single search field outside the <code>GridView</code> where the user can input keywords and by the time Search button is hit, the results will display in the <code>GridView</code> based on the keywords entered.</p>
<p>CONTROLLER</p>
<pre><code>public function actionIndex()
{
$session = Yii::$app->session;
//$searchModel = new PayslipTemplateSearch();
$PayslipEmailConfig = PayslipEmailConfig::find()->where(['company_id'=> new \MongoId($session['company_id'])])->one();
$payslipTemplateA = PayslipTemplate::find()->where(['company_id' => new \MongoId($session['company_id'])])->andwhere(['template_name' => 'A'])->one();
$payslipTemplateB = PayslipTemplate::find()->where(['company_id' => new \MongoId($session['company_id'])])->andwhere(['template_name' => 'B'])->one();
$pTemplateModel = PayslipTemplate::find()->where(['company_id' => new \MongoId($session['company_id'])])->all();
$user = User::find()->where(['_id' => new \MongoId($session['user_id'])])->one();
$module_access = explode(',', $user->module_access);
//$dataProvider = User::find()->where(['user_type' => 'BizStaff'])->andwhere(['parent' => new \MongoId($session['company_owner'])])->all();
$searchModel = new UserSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('index', [
'PayslipEmailConfig' => $PayslipEmailConfig,
'dataProvider' => $dataProvider,
'payslipTemplateA' => $payslipTemplateA,
'payslipTemplateB' => $payslipTemplateB,
'searchModel' => $searchModel,
]);
}
public function actionSearchresults($keyword)
{
$session = Yii::$app->session;
if ( $keyword == '') {
return $this->redirect(\Yii::$app->request->getReferrer());
} else {
$user = User::find()->where( [ '_id' => new \MongoId($id) ] )->one();
$searchModel = new PayslipTemplateSearch();
$payslipTemplateA = PayslipTemplate::find()->where(['company_id' => new \MongoId($session['company_id'])])->andwhere(['template_name' => 'A'])->one();
$payslipTemplateB = PayslipTemplate::find()->where(['company_id' => new \MongoId($session['company_id'])])->andwhere(['template_name' => 'B'])->one();
return $this->render('searchresults', [
'searchModel' => $searchModel,
'user' => $user,
'payslipTemplateA' => $payslipTemplateA,
'payslipTemplateB' => $payslipTemplateB,
]);
}
}
</code></pre>
<p>I asked a question connected to this problem here: <a href="https://stackoverflow.com/questions/32882097/main-search-form-in-yii2">Main Search Form in Yii2</a></p>
<p>It didn't due to some complications in Kartik's <code>Select2</code> search dropdown widget. Now I switched temporarily to a simple Yii2 search field.</p>
<p>VIEW</p>
<pre><code>echo $form->field($model, '_id')->textInput(array('placeholder' => 'search'))->label(false);
</code></pre>
<p>MODEL</p>
<pre><code><?php
namespace app\models;

public function rules()

->andFilterWhere(['like', 'user_type', $this->user_type]);
return $dataProvider;
}
}
</code></pre>
<p>Do you have any idea on how to I implement a single search? It's kind of a smarter search since it can search everything in the database table based on keywords inputted.</p>
<p>EDIT</p>
<p>When I search a keyword, say for example 'hello', it then gives me this url and error after hitting enter key:</p>
<p>URL: </p>
<blockquote>
<p><a href="http://localhost/iaoy-dev/web/index.php?r=payslip-template%2Fsearchresults&PayslipTemplateSearch%5B_id%5D=hello" rel="nofollow noreferrer">http://localhost/iaoy-dev/web/index.php?r=payslip-template%2Fsearchresults&PayslipTemplateSearch%5B_id%5D=hello</a></p>
</blockquote>
<p>Error message:</p>
<blockquote>
<p>Bad Request (#400) Missing required parameters: id</p>

Designing CardView while it's Parent is ConstraintLayout?
|
<p>I messed up while editing RelativeLayout inside Cardview that contains Relativelayout ! ConstraintLayout will change wrap_content of relative layout to 0 and adds tools:layout_editor_absoluteX="10dp" all textview inside Relative layout will collapse top right of the cardview !!! (element in the nested CardView gets aligned to the element outside of the CardView)</p>
<p>
</p>
<pre><code><android.support.v7.widget.CardView
android:id="@+id/card_view"
android:layout_gravity="center"
android:layout_width="357dp"
android:layout_height="114dp"
android:layout_margin="5dp"
app:cardCornerRadius="2dp"
app:contentPadding="10dp"
app:cardElevation="10dp"
tools:layout_editor_absoluteY="36dp"
app:cardBackgroundColor="@android:color/white"
tools:layout_editor_absoluteX="11dp">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
tools:layout_editor_absoluteX="10dp"
tools:layout_editor_absoluteY="10dp">
<TextView
android:text="TextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/textView2"

android:layout_toRightOf="@+id/textView2"
android:layout_toEndOf="@+id/textView2" />
</android.support.v7.widget.CardView>
</code></pre>
<p></p>
<p>any guide regarding designing RelativeLayout with ConstraintLayout would be great full, RelativeLayout can't be used anywhere while using ConstraintLayout? what is the guidline to use children of a CardView while using RelativeLayout while CardViews is a children of ConstraintLayout?</p>

How can I perform flood fill with HTML Canvas?
|
<p>Has anyone implemented a flood fill algorithm in javascript for use with HTML Canvas?</p>
<p>My requirements are simple: flood with a single color starting from a single point, where the boundary color is any color greater than a certain delta of the color at the specified point. </p>
<pre><code>var r1, r2; // red values
var g1, g2; // green values
var b1, b2; // blue values
var actualColorDelta = Math.sqrt((r1 - r2)*(r1 - r2) + (g1 - g2)*(g1 - g2) + (b1 - b2)*(b1 - b2))
function floodFill(canvas, x, y, fillColor, borderColorDelta) {
...
}
</code></pre>
<p>Update:</p>
<p>I wrote my own implementation of flood fill, which follows. It is slow, but accurate. About 37% of the time is taken up in two low-level array functions that are part of the prototype framework. They are called by push and pop, I presume. Most of the rest of the time is spent in the main loop. </p>

<p>BTW, when I call this, I use a custom stopFunction:</p>
<pre><code> stopFill : function (fillColor, seedColor, pixelColor) {
// Ignore alpha difference for now.
return Math.abs(pixelColor.r - seedColor.r) > this.colorTolerance || Math.abs(pixelColor.g - seedColor.g) > this.colorTolerance || Math.abs(pixelColor.b - seedColor.b) > this.colorTolerance;
},
</code></pre>
<p>If anyone can see a way to improve performance of this code, I would appreciate it. The basic idea is:
1) Seed color is the initial color at the point to start flooding.
2) Try four adjacent points: up, right, down and left one pixel.
3) If point is out of range or has been visited already, skip it.
4) Otherwise push point onto to the stack of interesting points.
5) Pop the next interesting point off the stack.
6) If the color at that point is a stop color (as defined in the stopFunction) then stop processing that point and skip to step 5.
7) Otherwise, skip to step 2.
8) When there are no more interesting points to visit, stop looping.</p>
<p>Remembering that a point has been visited requires an array with the same number of elements as there are pixels.</p>

How should I handle "java.net.SocketException: Connection reset" in multithread AWS S3 file upload?
|
<p>I have a ThreadPoolExecutorService to which I'm submitting runnable jobs that are uploading large (1-2 GB) files to Amazon's S3 file system, using the AWS Java SDK. Occasionally one of my worker threads will report a java.net.SocketException with "Connection reset" as the cause and then die.</p>
<p>AWS doesn't use checked exceptions so I actually can't catch SocketException directly---it must be wrapped somehow. My question is how I should deal with this problem so I can retry any problematic uploads and increase the reliability of my program.</p>
<p>Would the Multipart Upload API be more reliable?</p>
<p>Is there some exception I can reliably catch to enable retries?</p>
<p>Here's the stack trace. The com.example.* code is mine. Basically what the DataProcessorAWS call does is call <code>putObject(String bucketName, String key, File file)</code> on an instance of <code>AmazonS3Client</code> that's shared across threads.</p>

Best approach to real time http streaming to HTML5 video client
|
<p>I'm really stuck trying to understand the best way to stream real time output of ffmpeg to a HTML5 client using node.js, as there are a number of variables at play and I don't have a lot of experience in this space, having spent many hours trying different combinations.</p>
<p>My use case is:</p>
<p>1) IP video camera RTSP H.264 stream is picked up by FFMPEG and remuxed into a mp4 container using the following FFMPEG settings in node, output to STDOUT. This is only run on the initial client connection, so that partial content requests don't try to spawn FFMPEG again.</p>
<pre><code>liveFFMPEG = child_process.spawn("ffmpeg", [
"-i", "rtsp://admin:12345@192.168.1.234:554" , "-vcodec", "copy", "-f",
"mp4", "-reset_timestamps", "1", "-movflags", "frag_keyframe+empty_moov",
"-" // output to stdout
], {detached: false});
</code></pre>
<p>2) I use the node http server to capture the STDOUT and stream that back to the client upon a client request. When the client first connects I spawn the above FFMPEG command line then pipe the STDOUT stream to the HTTP response.</p>
<pre><code>liveFFMPEG.stdout.pipe(resp);
</code></pre>
<p>I have also used the stream event to write the FFMPEG data to the HTTP response but makes no difference</p>
<pre><code>xliveFFMPEG.stdout.on("data",function(data) {
resp.write(data);
}
</code></pre>
<p>I use the following HTTP header (which is also used and working when streaming pre-recorded files)</p>
<pre><code>var total = 999999999 // fake a large file
var partialstart = 0
var partialend = total - 1
if (range !== undefined) {
var parts = range.replace(/bytes=/, "").split("-");
var partialstart = parts[0];
var partialend = parts[1];
}
var start = parseInt(partialstart, 10);
var end = partialend ? parseInt(partialend, 10) : total; // fake a large file if no range reques
var chunksize = (end-start)+1;
resp.writeHead(206, {
'Transfer-Encoding': 'chunked'
, 'Content-Type': 'video/mp4'
, 'Content-Length': chunksize // large size to fake a file
, 'Accept-Ranges': 'bytes ' + start + "-" + end + "/" + total
});
</code></pre>
<p>3) The client has to use HTML5 video tags.</p>
<p>I have no problems with streaming playback (using fs.createReadStream with 206 HTTP partial content) to the HTML5 client a video file previously recorded with the above FFMPEG command line (but saved to a file instead of STDOUT), so I know the FFMPEG stream is correct, and I can even correctly see the video live streaming in VLC when connecting to the HTTP node server.</p>
<p>However trying to stream live from FFMPEG via node HTTP seems to be a lot harder as the client will display one frame then stop. I suspect the problem is that I am not setting up the HTTP connection to be compatible with the HTML5 video client. I have tried a variety of things like using HTTP 206 (partial content) and 200 responses, putting the data into a buffer then streaming with no luck, so I need to go back to first principles to ensure I'm setting this up the right way.</p>
<p>Here is my understanding of how this should work, please correct me if I'm wrong:</p>
<p>1) FFMPEG should be setup to fragment the output and use an empty moov (FFMPEG frag_keyframe and empty_moov mov flags). This means the client does not use the moov atom which is typically at the end of the file which isn't relevant when streaming (no end of file), but means no seeking possible which is fine for my use case.</p>
<p>2) Even though I use MP4 fragments and empty MOOV, I still have to use HTTP partial content, as the HTML5 player will wait until the entire stream is downloaded before playing, which with a live stream never ends so is unworkable.</p>
<p>3) I don't understand why piping the STDOUT stream to the HTTP response doesn't work when streaming live yet if I save to a file I can stream this file easily to HTML5 clients using similar code. Maybe it's a timing issue as it takes a second for the FFMPEG spawn to start, connect to the IP camera and send chunks to node, and the node data events are irregular as well. However the bytestream should be exactly the same as saving to a file, and HTTP should be able to cater for delays.</p>
<p>4) When checking the network log from the HTTP client when streaming a MP4 file created by FFMPEG from the camera, I see there are 3 client requests: A general GET request for the video, which the HTTP server returns about 40Kb, then a partial content request with a byte range for the last 10K of the file, then a final request for the bits in the middle not loaded. Maybe the HTML5 client once it receives the first response is asking for the last part of the file to load the MP4 MOOV atom? If this is the case it won't work for streaming as there is no MOOV file and no end of the file.</p>
<p>5) When checking the network log when trying to stream live, I get an aborted initial request with only about 200 bytes received, then a re-request again aborted with 200 bytes and a third request which is only 2K long. I don't understand why the HTML5 client would abort the request as the bytestream is exactly the same as I can successfully use when streaming from a recorded file. It also seems node isn't sending the rest of the FFMPEG stream to the client, yet I can see the FFMPEG data in the .on event routine so it is getting to the FFMPEG node HTTP server.</p>
<p>6) Although I think piping the STDOUT stream to the HTTP response buffer should work, do I have to build an intermediate buffer and stream that will allow the HTTP partial content client requests to properly work like it does when it (successfully) reads a file? I think this is the main reason for my problems however I'm not exactly sure in Node how to best set that up. And I don't know how to handle a client request for the data at the end of the file as there is no end of file.</p>
<p>7) Am I on the wrong track with trying to handle 206 partial content requests, and should this work with normal 200 HTTP responses? HTTP 200 responses works fine for VLC so I suspect the HTML5 video client will only work with partial content requests?</p>
<p>As I'm still learning this stuff its difficult to work through the various layers of this problem (FFMPEG, node, streaming, HTTP, HTML5 video) so any pointers will be greatly appreciated. I have spent hours researching on this site and the net, and I have not come across anyone who has been able to do real time streaming in node but I can't be the first, and I think this should be able to work (somehow!).</p>

<p>How can you delete an old clientID?</p>

DTrace missing Java frames with ustack(). Running on Joyent SmartOS infrastructure container
|
<p>I cannot get any Java stack with dtrace in a Joyent SmartOS instance. </p>
<p>I tried the <code>java:15.1.1</code> image and a plain SmartOS 'base64' image, where I installed openjdk 8.</p>
<p>I most basic example:
cat Loop.java </p>
<pre><code>[root@7e8c2a25-c852-4967-b60c-7b4fbd9a1de5 /demo]# cat Loop.java
class Loop {
public static void main(String[] args) throws InterruptedException {
while (true) {
System.out.println("Sleepy");
Thread.sleep(2000);
}
}
}
[root@7e8c2a25-c852-4967-b60c-7b4fbd9a1de5 /demo]# javac Loop.java
[root@7e8c2a25-c852-4967-b60c-7b4fbd9a1de5 /demo]# java Loop
</code></pre>
<p>I added the <code>libdtrace_forceload.so</code> as <a href="https://stackoverflow.com/questions/36166805/how-do-i-use-the-hotspot-dtrace-probes-on-smartos/36167514#36167514">recommended</a>.</p>
<pre><code>export LD_AUDIT_64=/usr/lib/dtrace/64/libdtrace_forceload.so
</code></pre>
<p>It is a 64 bit JVM:</p>
<pre><code>[root@7e8c2a25-c852-4967-b60c-7b4fbd9a1de5 /demo]# java -version
openjdk version "1.7.0-internal"
OpenJDK Runtime Environment (build 1.7.0-internal-pkgsrc_2015_05_29_19_05-b00)
OpenJDK 64-Bit Server VM (build 24.76-b04, mixed mode)
</code></pre>
<p>When I run dtrace, and use jstack, I get the C-stacks. However, the JAVA frames are the raw addresses, quite useless:</p>
<pre><code>[root@7e8c2a25-c852-4967-b60c-7b4fbd9a1de5 ~]# pgrep -fn "java Loop"
32597

Make draggable element sortable within droppable using jQuery UI
|
<p><strong>RESOLVED</strong></p>
<p>So I studied <code>sortable()</code> with the <code>connectWith</code> attribute a bit more and found the solution was simpler than I expected, but I was thinking about it sort of backwards because of <code>draggable()</code> and <code>droppable()</code>.</p>
<p>Here's the fiddle: <a href="http://jsfiddle.net/DKBU9/12/" rel="nofollow noreferrer">http://jsfiddle.net/DKBU9/12/</a></p>
<hr>
<p><em>Original question follows:</em></p>
<p>This is an extension of a previous SO question that I felt should be kept separate.</p>
<p>The original question is here: <a href="https://stackoverflow.com/questions/20964467/jquery-ui-clone-droppable-sortable-list-after-drop-event/20964766?noredirect=1#20964766">jQuery UI - Clone droppable/sortable list after drop event</a>. It regards reinitializing the droppable handler on cloned elements.</p>
<p>On top of that though, I'm trying to allow the elements that have been dragged from the initial list to be sorted within the droppable lists.</p>
<p>Here is a fiddle essentially illustrating the current behaviour as a result of the original question: <a href="http://jsfiddle.net/DKBU9/7/" rel="nofollow noreferrer">http://jsfiddle.net/DKBU9/7/</a></p>
<p>And the required code because SO likes to complain and bloat these posts:</p>
<p>HTML</p>
<pre><code><ul id="draggables">
<li>foo1</li>
<li>foo2</li>
<li>foo3</li>
</ul>
<ul class="droppable new">
</ul>
</code></pre>
<p>JS</p>
<pre><code>$(function() {
$('#draggables > li').draggable({
appendTo: 'document',
revert: 'invalid'
});
$('.droppable > li').draggable({
appendTo: 'document',
revert: 'invalid'
});
$('#draggables').droppable({
accept: '.droppable > li',
drop: function(event, ui) {
ui.draggable.detach().css({top: 0,left: 0}).appendTo($(this));
cleanUp();
}
});
initDrop($('.droppable'));
});
function initDrop($element) {
$element.droppable({
accept: function(event, ui) {
return true;
},
drop: function(event, ui) {
if($(this).hasClass('new')) {
var clone = $(this).clone();
$(this).after(clone);
$(this).removeClass('new');
initDrop( clone );
}
ui.draggable.detach().css({top: 0,left: 0}).appendTo($(this));
cleanUp();
}
}).sortable({
items: 'li',
revert: false,
update: function() {
cleanUp();
}
});
}
function cleanUp() {
$('.droppable').not('.new').each(function() {
if($(this).find('li').length == 0) {
$(this).remove();
}
});
}
</code></pre>
<p>Reference question: <a href="https://stackoverflow.com/questions/18399543/jquery-ui-combine-sortable-and-draggable">Jquery UI combine sortable and draggable</a></p>
<p>I've been trying to use this SO question to resolve my issue as the result is exactly what I'm trying to achieve, specifically the last fiddle provided in the comments of the accepted answer, but I can't seem to figure out how to adapt it to my code considering the minor differences. For example, the fiddle in that question clones the draggable rather than dragging the actual element and unlike mine doesn't allow elements to be dragged back into the initial list.</p>
<p>So any help to try to get that result for my code would be greatly appreciated.</p>
<p>Also, in that example, the <code>accept</code> attribute is set as a function to return true. What is the reason for this? Doesn't that just mean it will accept anything, or any draggable element?</p>
<p>EDIT: I read a couple answers that just used sortable() with the connectWith attribute, but for some reason I didn't think it did what I needed to, partly because I didn't want the initial list to be sortable as well. However, using sortable() alone seems to get the functionality I'm after but I just haven't yet adapted all the event handlers.</p>

Can't bind to 'ngIf' since it isn't a known property of 'md-card-title'
|
<p>I am learning <code>Angular2 RC5</code> with Angular2 material libraries and getting it to run in a <code>AspNetCore 1.0</code> app using <code>VisualStudio 2015.</code> I took a perfectly running <code>Angular2 RC5</code> single page application and tried to introduce lazy loading where only the login page will load first. When I have successfully logged in, I want to load the remaining pages. </p>
<p>When I clicked on the login button in SPA mode, I would redirect successfully to the DashboardComponent page which was preloaded with the login page - that was before I introduced lazy loading.
After following <a href="https://angular.io/docs/ts/latest/guide/ngmodule.html#!#lazy-load" rel="nofollow">this tutorial</a> I now get these errors</p>
<p><strong><em>Error Snippet</em></strong></p>
<blockquote>
<pre><code>EXCEPTION: Error: Uncaught (in promise): Template parse errors: Can't bind to 'ngIf' since it isn't a known property of 'md-card-title'.
1. If 'md-card-title' is an Angular component and it has 'ngIf' input, then verify that it is part of this module.
2. If 'md-card-title' is a Web Component then add "CUSTOM_ELEMENTS_SCHEMA" to the '@NgModule.schema' of this component to suppress this message. ("

</code></pre>
</blockquote>
<p>Why is the ngIf directive suddenly not working? It was working before I moved the Dashboard to load lazily post the login success.</p>
<p>I have gone all the way till using the Shared modules approach in the link I posted above. Is not using the Shared modules a cause for this issue? I presumed module sharing to be a way to clean up the code and not repeat stuff once everything works and nothing more than that. </p>
<p>My Dashboard is similar to the HeroesList page in the link I am following above, where in it loads some more pages the minute the DashboardModule is loaded. I have put breakpoints in the Dashboard page on the MVC side and have confirmed that the Dashboard and pages after does load lazily only on a successful login.</p>
<p>The error seems like its not able to get the reference of core angular references and/or angular2 material libraries. I have put all of those imports listed here in all the modules that would have them other than the routing modules</p>
<pre><code>import { NgModule } from '@angular/core';

<p>I'm trying to get Tuckey UrlRewriteFilter to tidy up URLs for my webapp. One problem I've got is that when spring-security notices that an anonymous user is trying to access a protected resource it redirects to a URL which includes the servlet path.</p>
<p>What I'd like is, by example:</p>
<pre><code>> GET http://localhost:8080/my-context/protected-resource
< Location: http://localhost:8080/my-context/login
</code></pre>
<p>What I currently get is:</p>
<pre><code>> GET http://localhost:8080/my-context/protected-resource
< Location: http://localhost:8080/my-context/-/login
</code></pre>
<p>Relevant documents I've found so far:</p>
<p>DefaultRedirectStrategy, which does the actual redirect in question: <a href="http://static.springsource.org/spring-security/site/docs/3.0.x/apidocs/org/springframework/security/web/DefaultRedirectStrategy.html" rel="nofollow noreferrer">http://static.springsource.org/spring-security/site/docs/3.0.x/apidocs/org/springframework/security/web/DefaultRedirectStrategy.html</a>. It has a contextRelative property which is tempting but I don't think is going to cut it, if I can even find a way of configuring it.</p>
<p>A blog post that helped get me this far: <a href="http://nonrepeatable.blogspot.com/2009/11/using-spring-security-with-tuckey.html" rel="nofollow noreferrer">http://nonrepeatable.blogspot.com/2009/11/using-spring-security-with-tuckey.html</a></p>
<p>What I'd like to know is:</p>
<ol>
<li>Can/should I convince Tuckey to rewrite the Location header. <outbound-rule> doesn't seem to help any here.</li>
<li>Can/should I somehow tweak the SS config to emit the rewritten URL. I don't think this is quite as tidy, as it'd break if rewrite was disabled.</li>
</ol>

Conditional Output Shiny UI
|
<p>I have survey data. I want to use Shiny to share results of my univariate and bivariate analyses with collaborators. In the survey there are numeric and factor variables. Depending on whether the person viewing the Shiny applications is interested in univariate/bivariate summaries, and depending on the variable type(s) they want to summarize I want different output to appear. </p>
<p>Specifically,</p>
<p>i) If univariate and numeric then display:</p>
<ul>
<li>Item response rate: <code>length() - sum(is.na())</code> </li>
<li><code>hist()</code> </li>
<li><code>summary()</code></li>
</ul>
<p>ii) If univariate and factor then display:</p>
<ul>
<li>Item response rate</li>
<li><code>barplot()</code></li>
<li><code>table()</code></li>
<li><code>prop.table()</code></li>
</ul>
<p>iii) If bivariate and numeric*numeric then display:</p>
<ul>
<li>Item response rate</li>
<li>Scatter graph: <code>plot(x,y)</code></li>
<li><code>summary(x)</code></li>
<li><code>summary(y)</code></li>
<li><code>cor(x,y,method="spearman")</code></li>
</ul>
<p>iv) If bivariate and factor*factor then display:</p>
<ul>
<li>Item response rate</li>
<li>Bar Chart...something like "rCharts nvd3 multiBarChart"</li>
<li><code>table(x,y)</code></li>
<li><code>prop.table(x,y)</code></li>
<li><code>chisq.test(x,y)</code></li>
</ul>
<p>v) If bivariate and (factor*numeric OR numeric*factor ) then display:</p>
<ul>
<li>Item response rate</li>
<li>boxplot</li>
<li>summary of numeric variable by factor variable: <code>by(numeric, factor, summary)</code></li>
<li>Kruskal Wallis Test <code>kruskal.test(numeric ~ factor)</code></li>
</ul>
<p>Currently, I have code to generate the desired output for all 5 steps as separate applications. I want to bring them together into 1 Shiny app. I am struggling conceptually with how to set up the <code>mainPanel()</code> display to be reactive to the different output that it will receive as a function of the choices the user is making on the <code>sidebarPanel()</code> UI. </p>
<p>Specifically,</p>
<ul>
<li>How to change <code>mainPanel()</code> UI headers to reflect different outputs</li>
<li>How to conceptually expand my code below to include multiple pieces of output (i.e. Below code works for a single piece <code>verbatimTextOutput()</code> but I don't know how to proceed for the multiple pieces/types of output I want to display as discussed in (i-iv) above. e.g. Text, tables, plots. </li>
</ul>
<p>Below is my code for the ui.R file:</p>
<pre><code>library(shiny)
shinyUI(pageWithSidebar(
headerPanel("Shiny Example"),
sidebarPanel(
wellPanel(
selectInput(inputId = "variable1",label = "Select First Variable:",
choices = c("Binary Variable 1" = "binary1",
"Binary Variable 2" = "binary2",
"Continuous Variable 1" = "cont1",
"Continuous Variable 2" = "cont2"),
selected = "Binary Variable 1"
)
),
wellPanel(
checkboxInput("bivariate", "Proceed to Bivariate Analysis", FALSE),
conditionalPanel(
condition="input.bivariate==true",
selectInput(inputId = "variable2",
label = "Select Second Variable:",
choices = c("Binary Variable 1" = "binary1",
"Binary Variable 2" = "binary2",
"Continuous Variable 1" = "cont1",
"Continuous Variable 2" = "cont2"),
selected = "Binary Variable 2"
)
)
)
),
mainPanel(
h5("Output"),
verbatimTextOutput("out")
)
))
</code></pre>
<p>Below is my simulated data and my server.R file:</p>
<pre><code>binary1 <- rbinom(100,1,0.5)
binary2 <- rbinom(100,1,0.5)
cont1 <- rnorm(100)
cont2 <- rnorm(100)
dat <- as.data.frame(cbind(binary1, binary2, cont1, cont2))
dat$binary1 <- as.factor(dat$binary1)
dat$binary2 <- as.factor(dat$binary2)
dat$cont1 <- as.numeric(dat$cont1)
dat$cont2 <- as.numeric(dat$cont2)
library(shiny)
library(rCharts)
shinyServer(function(input, output) {
inputVar1 <- reactive({
parse(text=sub(" ","",paste("dat$", input$variable1)))
})
inputVar2 <- reactive({
parse(text=sub(" ","",paste("dat$", input$variable2)))
})
output$out <- renderPrint({
if ( (input$bivariate==FALSE) & (is.factor(eval(inputVar1()))==TRUE) ) {
table(eval(inputVar1()))
} else {
if ( (input$bivariate==FALSE) & (is.numeric(eval(inputVar1()))==TRUE) ) {
summary(eval(inputVar1()))
} else {
if ( (input$bivariate==TRUE) & (is.factor(eval(inputVar1()))==TRUE) & (is.factor(eval(inputVar2()))==TRUE) ) {
table(eval(inputVar1()), eval(inputVar2()))
} else {
if ( (input$bivariate==TRUE) & (is.numeric(eval(inputVar1()))==TRUE) & (is.numeric(eval(inputVar2()))==TRUE) ) {
cor(eval(inputVar1()), eval(inputVar2()))
} else {
if ( (input$bivariate==TRUE) & (is.factor(eval(inputVar1()))==TRUE) & (is.numeric(eval(inputVar2()))==TRUE) ) {
by(eval(inputVar2()), eval(inputVar1()), summary)
} else {
if ( (input$bivariate==TRUE) & (is.numeric(eval(inputVar1()))==TRUE) & (is.factor(eval(inputVar2()))==TRUE) ) {
by(eval(inputVar1()), eval(inputVar2()), summary)
}
}
}
}
}
}
})
})
</code></pre>
<p>Any help you could provide would be greatly appreciated. Even simply showing how to adjust the code to render two pieces of desired output given choices of variables. And how to adjust headers to reflect named pieces of output. </p>
<p>Thanks in advance...Chris</p>

How to assign which MenuItems open onClick when multiple Menus are present on the material-ui Appbar using React?
|
<p>I created an AppBar with a menu based on the examples given on <a href="https://material-ui-next.com/demos/app-bar/" rel="noreferrer">the material UI site</a> and it works fine with one menu. But when I try adding a second dropdown menu, on clicking either icon, I get the same set of MenuItems showing up as seen in the image.</p>

Dynamic loading of external modules in webpack fails
|
<p>I am trying to set up the following architecture: a core React application that gets built with some basic functionality, and the ability to load additional React components at runtime. These additional React components can be loaded on-demand, and they are not available at build time for the core application (so they cannot be included in the bundles for the core application, and must be built separately). After researching for some time, I came across <a href="https://webpack.js.org/configuration/externals/" rel="noreferrer">Webpack Externals</a>, which seemed like a good fit. I am now building my modules separately using the following webpack.config.js:</p>
<pre><code>const path = require('path');
const fs = require('fs');
process.env.BABEL_ENV = 'production';
process.env.NODE_ENV = 'production';
const appDirectory = fs.realpathSync(process.cwd());
const resolveApp = relativePath => path.resolve(appDirectory, relativePath);
module.exports = {
entry: './src/MyModule.jsx',
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'MyModule.js',
library: 'MyModule',
libraryTarget: 'umd'
},
externals: {
"react": "react",
"semantic-ui-react": "semantic-ui-react"
},
module: {
rules: [
{
test: /\.(js|jsx|mjs)$/,
include: resolveApp('src'),
loader: require.resolve('babel-loader'),
options: {
compact: true,
},
}
]
},
resolve: {
extensions: ['.wasm', '.mjs', '.js', '.json', '.jsx']
}
};
</code></pre>
<p>Took a look at the generated MyModule.js file, and it looks correct to me.</p>
<p>Now, in my core app, I am importing the module as follows:</p>
<pre><code>let myComponent = React.lazy(() => import(componentName + '.js'));
</code></pre>
<p>where <code>componentName</code> is the variable that matches the name of my module, in this case, "MyModule" The name is not known at build time, and the file is not present in the src folder at build time. To avoid errors from webpack when building this code with an unknown import, I have added the following to my webpack.config.js for the core project:</p>
<pre><code>module.exports = {
externals: function (context, request, callback/*(err, result)*/) {
if (request === './MyModule.js') {
callback(null, "umd " + request);
} else {
callback();
}
}
}
</code></pre>
<p>I have confirmed that the function in externals gets called during the build, and the if condition is matched for this module. The build succeeds, and I am able to run my core application. </p>
<p>Then, to test dynamic loading, I drop <code>MyModule.js</code> into the static/js folder where the bundles for my core app live, then I navigate to the page in my core app that requests MyModule via <code>let myComponent = React.lazy(() => import(componentName + '.js'));</code></p>
<p>I see a runtime error in the console on the import line, </p>
<pre><code>TypeError: undefined is not a function
at Array.map (<anonymous>)
at webpackAsyncContext
</code></pre>
<p>My guess is it's failing to find the module. I don't understand where it is looking for the module, or how to get more information to debug.</p>

How many ways are there to configure the Spring framework? What are the differences between them technically? (Not pros or cons..)
|
<p>I am studying <a href="https://rads.stackoverflow.com/amzn/click/com/1118892925" rel="noreferrer" rel="nofollow noreferrer">this</a> book (which I would highly recommend), and I am confused about how the authors explain the way Spring framework can be configured.</p>
<p>You can see some code examples that are used in the book <a href="http://www.wrox.com/WileyCDA/WroxTitle/Beginning-Spring.productCd-1118892925,descCd-DOWNLOAD.html" rel="noreferrer">here</a>. (They are available to anyone..) The code I am referring the will be the code from chapter 2, if you would like to take a look.</p>
<p>The book states that there are <strong>3 ways to configure the Spring Container</strong>.</p>
<hr />
<p><strong>XML - based configuration</strong></p>
<p>This will require an xml file that resembles something like this:</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" ...>
<bean id="accountService" class="com.wiley.beginningspring.ch2.AccountServiceImpl">
<property name="accountDao" ref="accountDao"/>
</bean>
<bean id="accountDao" class="com.wiley.beginningspring.ch2.AccountDaoInMemoryImpl">
</bean>
</beans>
</code></pre>
<p>And then in order to bootstrap Spring, the code that will be used will be:</p>
<pre><code>ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("/com/wiley/beginningspring/ch2/ch2-beans.xml");
</code></pre>
<p>I do not have any confusions at this moment.</p>
<hr />
<p><strong>Java Based Configuration</strong></p>
<p>In this Configuration method, there will be a class for the configuration as follows:</p>
<pre><code>@Configuration
public class Ch2BeanConfiguration {
@Bean
public AccountService accountService() {
AccountServiceImpl bean = new AccountServiceImpl();
bean.setAccountDao(accountDao());
return bean;
}
@Bean
public AccountDao accountDao() {
AccountDaoInMemoryImpl bean = new AccountDaoInMemoryImpl();
return bean;
}
}
</code></pre>
<p>and the code that is responsible for bootstrapping Spring looks like:</p>
<pre><code>ApplicationContext applicationContext
= new AnnotationConfigApplicationContext(Ch2BeanConfiguration.class);
</code></pre>
<p>So up to here, all is clear for me. (Kind of..) I would also like to note that, here we actually have an Annotation which is called @Configuration...</p>
<hr />
<p><strong>Annotation Based Configuration</strong></p>
<p>The last configuration method available, explained in the book is the <strong>Annotation Based Configuration</strong>.</p>
<p>There is an xml file just like we had in the XML-Based Configuration, however a much smaller one:</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" ...>
<context:component-scan base-package="com.wiley.beginningspring.ch2"/>
</beans>
</code></pre>
<p>All the beans have Annotations such as:</p>
<pre><code>@Component, @Service
</code></pre>
<p>etc..</p>
<p>And all the dependencies have the annotations:</p>
<pre><code>@Autowired
</code></pre>
<p>so that beans can be injected.</p>
<p>The way Spring framework bootstrapped in this configuration method is as follows:</p>
<pre><code>ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("/ch2-beans.xml");
</code></pre>
<hr />
<p><strong>Here are my questions:</strong></p>
<p>Why is the (so-called) <strong>Annotation Based Configuration</strong> actually using <strong>ClassPathXmlApplicationContext</strong> but not <strong>AnnotationConfigApplicationContext</strong> above? The latter seems much more appropriate to be used in a Configuration that has the words "Annotation Based" in it, isn 't it?</p>
<p>The <strong>Java Based Configuration</strong> explained in the book seems like what should be called <strong>Annotation Based Configuration</strong>.?</p>
<p>And the way Annotation Based Configuration explained in the book actually seems to me something like: XML-Based Configuration with Autowired beans. It does not even have the @Configuration annotation, which the "Java Based Configuration" has..</p>
<p>How many ways are there to configure Spring framework?</p>

Toggle Show And Hide Only Some Table Rows
|
<p>I am trying to show/hide (via a toggle mechanism) only certain rows in my table. I have gotten somewhat close, code is below. What I was reading about in other questions regarding this is the use of style id's and I have tried that but it fails for me. So that is why I used 'hide=yes' and pass that into the toggle function.</p>
<p>This is going to be a table with a couple of hundred entries that when I click toggle can be reduce down to less than 30 on any given day. </p>
<p>Is there a better way to do this?</p>
<pre><code><html>
<head>
<script>
function toggle(thisname) {
tr=document.getElementsByTagName('tr')
for (i=0;i<tr.length;i++){
if (tr[i].getAttribute(thisname)){
if ( tr[i].style.display=='none' ){
tr[i].style.display = '';
}
else {
tr[i].style.display = 'none';
}
}
}
}
</script>
</head>
<body>
<span onClick="toggle('hide');">TOGGLE</span><br /><br />
<table>
<tr ><td >display this row 1</td></tr>
<tr hide=yes ><td>hide this row 1</td></tr>
<tr><td>display this row 2</td></tr>
<tr hide=yes ><td>hide this row 2</td></tr>
<tr hide=yes ><td>hide this row 3</td></tr>
<tr><td>display this row 3</td></tr>
<tr><td>display this row 4</td></tr>
<tr><td>display this row 5</td></tr>
<tr><td>display this row 6</td></tr>
<tr hide=yes ><td>hide this row 4</td></tr>
<tr hide=yes ><td>hide this row 5</td></tr>
<tr><td>display this row 7</td></tr>
<tr hide=yes ><td>hide this row 6</td></tr>
<tr hide=yes ><td>hide this row 7</td></tr>
</table>
</body>

Relational attribute in Yii2 form
|
<p>I am trying to get to figure out the proper way of handling a form receiving relational data in Yii2. I haven't been able to find any good examples of this. I have 2 models Sets and SetsIntensity, every Set may have one SetsIntensity associated with it. I'm am trying to make a form where you can input both at the same time. I'm not sure how to handle getting the input for a particular field 'intensity' in SetsIntensity.</p>
<p>Where</p>
<pre><code>$model = new \app\models\Sets();
</code></pre>
<p>If I put it in the field like this client validation won't work and the attribute name is ambiguous and saving becomes difficult</p>
<pre><code><?= $form->field($model, 'lift_id_fk') ?>
<?= $form->field($model, 'reps') ?>
<?= $form->field($model, 'sets') ?>
<?= $form->field($model, 'type') ?>
<?= $form->field($model, 'setsintensity') ?>
</code></pre>
<p>I would like to do something like this but I get an error if I do</p>
<pre><code><?= $form->field($model, 'setsintensity.intensity') ?>
Exception (Unknown Property) 'yii\base\UnknownPropertyException' with message 'Getting unknown property: app\models\Sets::setsintensity.intensity'
</code></pre>
<p>I could do make another object in the controller <code>$setsintensity = new Setsintensity();</code> but I feel this is a cumbersome solution and probably not good practice especially for handling multiple relations</p>
<pre><code><?= $form->field($setsintensity, 'intensity') ?>
</code></pre>
<p>relevant code from SetsModel</p>
<pre><code>class Sets extends \yii\db\ActiveRecord
{
public function scenarios() {
$scenarios = parent::scenarios();
$scenarios['program'] = ['lift_id_fk', 'reps', 'sets', 'type', 'intensity'];
return $scenarios;
}
public function rules()
{
return [
[['lift_id_fk'], 'required'],
[['lift_id_fk', 'reps', 'sets','setsintensity'], 'integer'],
[['type'], 'string', 'max' => 1],
['intensity', 'safe', 'on'=>'program']
];
}
public function getSetsintensity()
{
return $this->hasOne(Setsintensity::className(), ['sets_id_fk' => 'sets_id_pk']);
}
</code></pre>
<p>SetsIntensity Model</p>
<pre><code>class Setsintensity extends \yii\db\ActiveRecord
{
public static function tableName()
{
return 'setsintensity';
}
public function rules()
{
return [
[['sets_id_fk', 'intensity', 'ref_set'], 'required'],
[['sets_id_fk', 'intensity', 'ref_set'], 'integer']
];
}
public function getSetsIdFk()
{
return $this->hasOne(Sets::className(), ['sets_id_pk' => 'sets_id_fk']);
}
}
</code></pre>
<p>I was also thinking maybe I could put in a <code>hasOne()</code> relation for the specific attribute 'intensity' in 'Sets'</p>

This constraint cannot be enabled as not all values have corresponding parent values
|
<p>I have three nested tables in a dataset. I display the data based on the language ID, ie: EN is 1 FR is 2 and NL is 3. French and english exist in the database but Dutch does not exist yet and when the user selects NL I get the following error:</p>
<blockquote>
<p>This constraint cannot be enabled as not all values have corresponding
parent values.</p>

<p>Below is the code that I use to get the data. The error happens when I try to create relations in the dataset.</p>
<pre><code> (ds.Relations.Add(new DataRelation("Cat_SubCat", dk1, dk2));
</code></pre>
<p>Now my question is, how can I check if the value exists in the dataset or database with the given code below?</p>
<pre><code> public static DataTable GetData(Int32 languageID)
{
DataSet ds = new DataSet();
string commandText = @"SELECT * FROM AlacarteCat where languageID = @ID;

using (SqlConnection myConnection = new SqlConnection(Common.GetConnectionString("SQLConnectionString")))
{

Writing Byte Array To Binary File Javascript
|
<p>I am trying to write a script that generates random numbers these number then are converted to groups of 4Bytes each then these 4-bytes-groups are put into an Uint8Array finally I try to save the array to binary file. Here is my code:</p>
<pre><code><html>
<head>
<title>Raandom Number Generator</title>
</head>
<body>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="filesaver.min.js"></script>
<script type="text/javascript">
$(function() {
if (!Date.now) {
Date.now = function() {
return new Date().getTime();
};
}
alert("started");
var currentMousePos = {
x : -1,
y : -1
};
var randomData = [];
var bytes = new Int8Array(4);
$(document).mousemove(function(event) {
if(randomData.length>=1231){
$(document).unbind('mousemove');
console.log("Finished generating numbers ... trying to save file");
randomData = new Uint8Array(randomData);
var blob = new Blob(randomData, {type: "application/octet-stream"});
saveAs(blob, "rand.bin");
return;
}
currentMousePos.x = event.pageX;
currentMousePos.y = event.pageY;
var longRandomNumber = Date.now() * (event.pageX + 1)
* (event.pageY + 1);
for ( var i = 3; i >= 0; i--) {
bytes[i] = longRandomNumber & (255);
longRandomNumber = longRandomNumber >> 8
}
for ( var i = 0; i < 4; i++) {
randomData.push(bytes[i]);
}
console.log(randomData.length);
});
})
</script>
</body>
</html>
</code></pre>
<p>The problem is that the generated file contains numbers <code>plain numbers</code> for example an element in the Uint8Array may be 65, in my understanding to binary this value should be saved as capital letter <strong>A</strong> but it is stored as <strong>65</strong> instead</p>
<p><strong><em>Note</em></strong></p>
<p>filesaver.min.js is a library that I use to save files from JS (<a href="https://github.com/eligrey/FileSaver.js/" rel="nofollow">Link on GitHub</a>)</p>

Apache POI Java Excel Performance for Large Spreadsheets
|
<p>I have a spreadsheet I'm trying to read with POI (I have both xls and xlsx formats), but in this case, the problem is with the xls file. My spreadsheet has about 10,000 rows and 75 columns, and reading it in can take several minutes (though Excel opens in a few seconds). I'm using the event based reading, rather than reading the whole file into memory. The meat of my code is below. It's a bit messy right now, but it's really just a long switch statement that was mostly copied from the POI examples.</p>
<p>Is it typical for POI performance using the event model to be so slow? Is there anything I an do to speed this up? I think several minutes will be unacceptable for my application.</p>

Visual Studio Error: "Object reference not set to an instance of an object" when clicking on a project and opening Properties
|
<p>I have a weird behavior of Visual Studio 2013 (and 2010), that i cant seem to fix.</p>
<p>I know this is not directly related to programming (similar questions achieve the same error message via code, so i assume it is code within VisualStudio that has a problem).</p>
<p>My projects are C++.</p>
<p>Whenever i click on a project and open its properties, i get the following error box:</p>
<p><img src="https://i.stack.imgur.com/HUZyw.png" alt="Error Message"></p>
<p>with the text:</p>
<blockquote>
<p>Object reference not set to an instance of an object.</p>
</blockquote>
<p>I can trigger that error message by selecting "Configuration Properties -> General". The view then does not show the information for "General".</p>
<p>My setting is the following: Windows 7 Enterprise SP1 64bit, Visual Studio 2010 (i need the compiler) and Visual Studio 2013 Professional (Update 4).</p>
<p>I have to work with these extensions:</p>
<ul>
<li>IBM Clearcase Integration</li>
<li>IBM RTC VS Integration</li>
<li>Visual Assist X</li>
<li>Xoreax Incredibuild</li>
</ul>
<p>What i did try without success:</p>
<ul>
<li>Remove all VS related files/folders in
<ul>
<li><code>%APPDATA%\..\Local\Microsoft</code></li>
<li><code>%APPDATA%\..\Roaming\Microsoft</code></li>
<li><code>%PROGRAMFILES%</code></li>
<li><code>%PROGRAMFILES(X86)%</code></li>
<li><code>%USERPROFILE%\Documents</code></li>
</ul></li>
<li>Repair/Reinstall VS2010 and VS2013 (i always installed VS2010 first)</li>
<li>Reinstall .NET Framework 4.5.2</li>
<li>Create a new project from within VS2013, i get the usual error plus:<img src="https://i.stack.imgur.com/z8nP0.png" alt="new_proj_error"></li>
<li>Use TotalUninstaller as described <a href="https://stackoverflow.com/a/28050106/875020">here</a> to remove all extensions</li>
<li>Hooking into the devenv process with WinDBG did not work (in non-invasive i couldnt get it to run)</li>
<li>Start devenv.exe with <a href="https://msdn.microsoft.com/en-us/library/ms241278.aspx" rel="nofollow noreferrer">safemode</a> and <a href="https://msdn.microsoft.com/en-us/library/ms241272.aspx" rel="nofollow noreferrer">log</a></li>
<li>Uninstall NuGet as proposed <a href="https://stackoverflow.com/a/17312698/875020">here</a></li>
<li>Create new solution and delete old .suo and .sdf files</li>
<li>Look at output <img src="https://i.stack.imgur.com/O8PO8.png" alt="output"> of <a href="https://technet.microsoft.com/en-us/library/bb896645.aspx" rel="nofollow noreferrer">ProcMon</a> while triggering the error. I checked the registry for that key: nonexistent</li>
<li>Look at <a href="https://gist.github.com/anonymous/2e32538548fcbf10c204" rel="nofollow noreferrer">logfile</a> at <code>%APPDATA%\..\Roaming\Microsoft\VisualStudio\12.0\ActivityLog.xml</code> generated via /log: the keys are found within other keys of the value "(Default)". No clue on how to interpret that</li>
<li>Reset all user settings via the (also secret) options named <a href="https://stackoverflow.com/a/19460071/875020">here</a></li>
<li>Run .NET <a href="https://support.microsoft.com/en-us/kb/2698555" rel="nofollow noreferrer">Fixing Tools</a> and <a href="https://support.microsoft.com/en-us/kb/929833" rel="nofollow noreferrer">SFC</a></li>
<li>Clean (remove from) registry
<ul>
<li><code>HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\</code></li>
<li><code>HKEY_LOCAL_MACHINE\Software\Microsoft\VisualStudio\</code></li>
</ul></li>
</ul>
<p>So my questions are</p>
<ul>
<li>How could i further debug the problem</li>
<li>How can i really delete/reset all user settings and files and cleanup the registry</li>
<li>Could this be related to solutions or projects</li>
<li>Any third party components known to be problematic? .Net Frameworks?</li>
</ul>

How to pass props to Screen component with a tab navigator?
|
<p>This is my first post on StackOverflow, so apologies if I'm not following the correct format.</p>
<p>I'm building my first app using <code>tab navigator from React Navigation v 5.x</code> and have run into a big problem when passing props from one screen to another</p>
<p>What I want to achieve is to:</p>
<ol>
<li>Make changes to a list of data in one of my screens.</li>
<li>Have those changes affect what happens on another screen.</li>
</ol>
<p>I have tried <a href="https://reactnavigation.org/docs/hello-react-navigation/#passing-additional-props" rel="noreferrer">this</a> (I failed to set the props to pass down), <a href="https://stackoverflow.com/questions/57186298/react-native-pass-props-from-one-screen-to-another-screen-using-tab-navigator">this</a> (Deprecated version of react-navigation) and <a href="https://stackoverflow.com/a/56764509/12974771">this</a> (Also old version of react-navigation).</p>
<p>and Redux but there are no examples available with the current version of react navigation.</p>
<p>I'm at the end of my rope with this and really need some step by step on how to achieve this.
Here's a rough sketch of what I want to do:</p>
<p><a href="https://i.stack.imgur.com/rbSCL.png" rel="noreferrer"><img src="https://i.stack.imgur.com/rbSCL.png" alt="enter image description here" /></a></p>
<p>The way I thought about it is sending the parent state down as props via callback, but I can't find a way to send props through the screen components in the up-to-date version of react navigation...</p>
<p>This is my navigation setup:</p>
<pre class="lang-js prettyprint-override"><code>const Tab = createBottomTabNavigator()
export default class MyApp extends Component{
constructor(props) {
super(props);
}
render(){
return (
<NavigationContainer>
<Tab.Navigator
screenOptions={({ route }) => ({
tabBarIcon: ({ focused, color, size }) => {
let iconName;
if (route.name === 'My tests') {
iconName = focused ? 'ios-list-box' : 'ios-list';
} else if (route.name === 'Testroom') {
iconName = focused ? 'ios-body' : 'ios-body';
}
return <Ionicons name={iconName} size={size} color={color} />;
},
})}
tabBarOptions={{
activeTintColor: 'tomato',
inactiveTintColor: 'gray',
}}>
<Tab.Screen name="My tests" component={MyTests}/> //This is where I want to send props
<Tab.Screen name="Testroom" component={TestRoom} /> //This is where I want to send props
</Tab.Navigator>
</NavigationContainer>
)
}
}
</code></pre>
<p>I've read <a href="https://reactnavigation.org/docs/redux-integration" rel="noreferrer">this</a> but it makes no sense to me. How does this fit into a tree of components? What goes where? Please help!</p>

Application error with MyFaces 1.2: java.lang.IllegalStateException: No Factories configured for this Application
|
<p>For my app I'm using <strong>Tomcat 6.0.x</strong> and <strong>Mojarra 1.2_04</strong> JSF implementation.
It works fine, just I would like to switch now to <strong>MyFaces 1.2_10</strong> impl of JSF.</p>
<p>During the deployment of my app a get the following error:</p>
<pre><code>ERROR [org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/myApp]] StandardWrapper.Throwable
java.lang.IllegalStateException: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml.
A typical config looks like this;
<listener>
<listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>
at javax.faces.FactoryFinder.getFactory(FactoryFinder.java:106)
at javax.faces.webapp.FacesServlet.init(FacesServlet.java:137)

at org.apache.catalina.core.StandardContext.start(StandardContext.java:4371)
...
</code></pre>
<p>Here is part of my web.xml configuration:</p>
<pre><code> <servlet>
<servlet-name>Faces Servlet</servlet-name>
<!-- <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> -->
<servlet-class>org.apache.myfaces.webapp.MyFacesServlet</servlet-class>

</servlet>
...
<listener>
<listener- class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>
</code></pre>
<p>Has anyone experienced similar error, and what should I do i order to fix it? Thanx!</p>
<p><strong>EDIT:</strong></p>
<p>I was able to fix the problem. Since I am using delegator for <strong>FacesServlet</strong>, it turned out that this delegator was causing the problem.
All I needed to do is to make this class implement <strong>DelegatedFacesServlet</strong>, and I've removed <em>org.apache.myfaces.webapp.StartupServletContextListener</em>. Here is my web.xml now:</p>
<pre><code> <servlet>
<servlet-name>Faces Servlet</servlet-name>
<!-- <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> -->
<servlet-class>org.apache.myfaces.webapp.MyFacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

Error in Angular ng serve static ɵfac: i0.ɵɵFactoryDef<ShepherdService>
|
<p>I had to install a project in another pc, I use Angular v 9.1.0 but after I run npm install I have this error:</p>
<blockquote>
<p>ERROR in node_modules/angular-shepherd/lib/shepherd.service.d.ts:64:18 - error TS2314: Generic type 'ɵɵFactoryDef' requires 2 type argument(s).</p>
<p>64 static ɵfac: i0.ɵɵFactoryDef;</p>
</blockquote>
<p>I have the same version of the package in both pc <code>angular-shepherd": "^0.5.0</code></p>
<p>I already tried to remove and reinstall node_modules and also the package angular-shepherd but I still have the error.
In the old pc, all works well.

Attempt to invoke virtual method 'int java.lang.String.hashCode()'
|
<p>I'm trying to load images from URL into girdview using Volley Library. For this I'm following <a href="http://www.101apps.co.za/index.php/articles/using-volley-to-download-cache-and-display-bitmaps.html" rel="noreferrer">this</a> tutorial. When I run my project, it collects all URLs from server database and then store in arraylist. But doesn't displays images. And I am getting <code>java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.String.hashCode()' on a null object reference</code> error. It doesn't even point to any line number of code where I'm getting this error. See below Logcat Output :</p>
