In CustomView, only alpha Animation doesn't work
|
<p>I make my custom view. and I also make my custom view (making Circle). But In my custom view, Alpha Animation only don`t work.... </p>
<p>My Customview extends linearlayout</p>
<pre><code>public class mylayout extends FrameLayout implements View.OnClickListener {
......
public mylayout(Context context){
super(context);
init(context);
}
void init(Context context){
this.setLayoutParams(new
LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT));
mButton = new Button(getContext());
mButton.setText("Delete all Created Circle.");
mButton.setId(10);
mButton.setOnClickListener(this);
bitmap = BitmapFactory.decodeResource(context.getResources(),
R.drawable.change_sea01);
this.addView(mButton,new
LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
}
@Override
public boolean onTouchEvent(MotionEvent event) {
// TODO Auto-generated method stub
if(event.getAction() == MotionEvent.ACTION_DOWN) {
this.addView(new MyCircleView(getContext(), (int)event.getX(),
(int)event.getY()));
return true;
} else if(event.getAction() == MotionEvent.ACTION_MOVE) {
this.addView(new MyCircleView(getContext(),(int)event.getX(),
(int)event.getY()));
return true;
}
return super.onTouchEvent(event);
}
</code></pre>
<p>This is myCircle Class that make circle on touching point(x,y)</p>
<pre><code>class MyCircleView extends ImageView{
.............
public MyCircleView(Context context, int xPos, int yPos) {
super(context);
pnt = new Paint();
pnt.setAntiAlias(true);

Application not working, beginner
|
<p>i am fairly new to android programming and usually find my answers to my problems by searching, but this one i just cant and its very confusing.
The code itself doesn't show any signs of problems, well i do get 2 java exception breakpoints but i dont know how to fix those as they are "unknown"but when i run it on the emulator it says the application has stopped unexpectedly force close. I try to debug it but i dont know how to do it that well. any way here are the codes btw the app is just a test all it to do is have buttons that take me to other "pages" and back. I would appreciate any help.</p>
<p>Main java file</p>
<pre><code>package com.simbestia.original;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class original extends Activity implements View.OnClickListener {
Button button1, button2;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
button1 = (Button) findViewById(R.id.pagetwo);
button2 = (Button) findViewById(R.id.main);
button1.setOnClickListener(this);
button2.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.pagetwo:
setContentView(R.layout.pagetwo);
break;
case R.id.main:
setContentView(R.layout.main);
break;
}
}
}
</code></pre>
<p>Main xml</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
<Button android:text="pagetwo" android:id="@+id/pagetwo" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
</LinearLayout>
</code></pre>
<p>Well here is what i change the code to this one is just one button but it works with multiple and i made a class for every page...</p>
<pre><code>package com.simbestia.test;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class main extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button mainmenu = (Button) findViewById(R.id.mainmenu);
mainmenu.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent myIntent = new Intent(view.getContext(), mainmenu.class);
startActivityForResult(myIntent, 0);
}
});
}
</code></pre>
<p>}</p>
<p>Works how i wanted to so its all good i guess ty again</p>

<p>I'm trying to make a post request endpoint to send some form values to my database. When I test the request with postman, I get a 400 bad request error and this message in my console</p>
<p>JSON parse error: Cannot deserialize value of type <code>abcd.Model.Quote</code> from Array value (token <code>JsonToken.START_ARRAY</code>);</p>
<p>this is my controller:</p>

getData.executeUpdate();
return true;
}
catch (SQLException e) {
e.printStackTrace();
}
return false;
}
</code></pre>
<p>Thank you for your help.</p>
<p>UPDATE: this is the POST request im sending in postman:</p>
<pre><code>[

Class SpringHibernateJpaPersistenceProvider does not implement the requested interface PersistenceProvider

<p>If you'll note, i'm including a dependency for the Jackson library because the list of books should return as a JSON object. I don't think that's a poblem but just saying - and I could probably have remoed that for this but then when it runs, the list of books would be unintelligible to me getting a response when/if it worked. What am I doing wrong???</p>

Optimization in resetting the values of an array
|
<p>Good evening everyone, I ask you my question by specifying that I have found a solution, but I would be interested to know if it can be optimized and improved to favor performance.
I have the following subject given in response to a call to my server:</p>
<pre><code>{
"status": 200,
"error_code": 0,
"data": {
"2022-04-15": {
"dots": [
2
]
},
"2022-04-19": {
"dots": [
2
]
},
"2022-04-20": {
"dots": [
1
]
},
"2022-04-25": {
"dots": [
1
]
},
"2022-04-26": {
"dots": [
2,
3
]
},
"2022-04-27": {
"dots": [
3
]
},
"2022-04-28": {
"dots": [
3
]
}
}
}
</code></pre>
<p>Now I am using a library for react native (specifically react-native-calendars) and I need to reformat the response of my server, replacing within the object dots the numbers 1, 2, 3 of the static objects I have defined as follows :</p>
<pre><code>const data1 = {
key: "data1",
color: Colors.color40,
};
const data2 = {
key: "data2",
color: Colors.colorYellow,
};
const data3 = {
key: "data3",
color: Colors.color44,
};
const totalData = {
1: data1,
2: data2,
3: data3,
};
</code></pre>
<p>According to the react native calendars documentation, I need to have an object structured like this as a final result:</p>
<pre><code>const vacation = {key: 'vacation', color: 'red', selectedDotColor: 'blue'};
const massage = {key: 'massage', color: 'blue', selectedDotColor: 'blue'};
const workout = {key: 'workout', color: 'green'};
<Calendar
markingType={'multi-dot'}
markedDates={{
'2017-10-25': {dots: [vacation, massage, workout]},
'2017-10-26': {dots: [massage, workout]}
}}
/>;
</code></pre>
<p>To get the expected result, I wrote the following function:</p>
<pre><code> const formattedCalendarDots = (obj) => {
Object.keys(obj).forEach((key) => {
obj[key] = { dots: obj[key].dots.map((el) => totalData[el]) };
});
return obj;
};
</code></pre>
<p>I ask the more experienced. is this a good solution?
Again, this function does what I ask, but I wanted to know if it was possible to optimize it in excellent performance.
Thanks to those who will answer</p>

ifstream sets eof flag when file is opened

<p>I am trying to read from a text file using ifstream, but for some reason when I use g++ to compile, the eof flag is set before anything is even read from the file. Testing if the file is in fact open does return true. When using visual studio to compile it works correctly. Even when the file "file.txt" exists, the program below prints 1 when compiled with g++.</p>

std::ifstream file("file.txt");

Program crashing in munmap

<p>I am working at an Android app that, among other things, must send background data to a ftp server. The code that does this is written in native code, using standard Linux functions.</p>

<p>The relevant stuff in the logcat is this:</p>
<pre><code>07-13 21:30:50.557 10268-10376/? E/com.example.ftp_cam: Before munmap

</code></pre>
<p>So it seems that the code crashes in munmap. However, the code continues for a bit after the segfault, because it shows the file upload completed message (which is further down the code).</p>
<p>Any idea what might the problem be?
Thanks for your time!</p>

Why may a generic type not use a concrete version of itself?
|
<h3>TL;DR</h3>
<ul>
<li>Why may we not use a concrete version of a generic type within its own generic implementation? Since it's a concrete type, I see no issues with "recursive typing". Is this a design decision? Or a current limitation?</li>
</ul>
<hr />
<p><strong>Background</strong></p>
<p>When playing around with generics, I stumbled over the following (for me, previously unknown) curiosity:</p>
<pre><code>struct Foo<T> { let foo: T }
struct Bar<U> {
let bar: U
func foobar() -> Foo<Bar> {
/* ^^^ Bar<U> inferred */
// no matter of the actual implementation ...
return Foo(foo: self)
}
// even without inference help from the implemention
func nilFoobar() -> Foo<Bar>? { return nil }
}
</code></pre>
<p>Particularly how the return type of <code>foobar()</code> needn't specify the placeholder type of <code>Bar</code> (which in turn is the placeholder for the generic <code>Foo</code> return), as this seems to be inferred as the same placeholder type as <code>Self</code> (concrete <code>U</code> in <code>Self</code>). I.e., as I see it, the above is equivalent to (except for the Option-click description of the <code>foo()</code> method in Xcode)</p>
<pre><code>struct Foo<T> { let foo: T }
struct Bar<U> {
let bar: U
func foobar() -> Foo<Bar<U>> {
return Foo(foo: self)
}
func nilFoobar() -> Foo<Bar<U>>? { return nil }
}
</code></pre>
<p>Since <code>Bar</code> in the return type of <code>foobar()</code> is inferred<sup>†</sup> as <code>Bar<U></code>, I realized that this in turn should disallow a generic types using concrete versions of itself (something I've never had or have a reason to do ...). As expected, this theory holds:</p>
<pre><code>struct Foo<T> { let foo: T }
struct Bar<U> {
let bar: U
func foobar() -> Foo<Bar<Int>> {
return Foo(foo: Bar(bar: 1))
/* ^ error: 'Int' is not convertible to 'U' */
}
// concrete version of other generic type naturally allowed
func fooint() -> Foo<Int> {
return Foo(foo: 1)
}
}
</code></pre>
<p><sub>[†] Rather than inferred, perhaps a shortcut for is a better description? Since it compiles even without an actual implementation to fall back to w.r.t. inference.</sub></p>
<p><strong>Question</strong></p>
<p>I don't have any use for using concrete versions of <code>Self</code> within a generic type, but with some imagination, I could see this being used in some corner case context. More so, out of a technical viewpoint (and curiosity), I'm interested in why this seems to be disallowed by design.</p>
<ul>
<li>Why may we not use a concrete version of a generic type within its own implementation? Since it's a concrete type, I see no issues with "recursive typing". Is this a design decision? A current limitation?</li>
</ul>
<p>I hope this question doesn't fall under opinion-based. Given the open official community of Swift, maybe someone can shed official-connecting light for the reasoning as to why this should be disallowed by design (or is it simply a current "limitation"?).</p>

Problems with scrolling in HorizontalListView(android)
|
<p>I use a <code>HorizontalListView</code> to scroll I use the code below (method setOnItemClickListener)</p>
<pre><code> listview.post(new Runnable() {
public void run() {
int centerX = listview.getChildAt(position).getLeft();
listview.scrollTo(centerX);
}
});
</code></pre>
<p>but there is a problem when position reaches <code>3</code> or more , then I get an error:</p>
<pre><code>12-28 01:33:37.814 20841-20841/com.example.SmsService E/AndroidRuntime﹕ FATAL EXCEPTION: main

<p>I think that probably because I use <strong>looped listView</strong>:</p>
<pre><code> @Override
public int getCount() {
return Integer.MAX_VALUE;//
}
</code></pre>
<p><strong>how I could fix this problem?</strong> And maybe there are other ways scroll listView? (Scrolling Smooth does not work ) <a href="https://gist.github.com/diha-o/c004352966f07bd02614" rel="nofollow">My Class.</a> And .xml file:</p>

How can I invoke this workflow?
|
<pre><code>static void Main(string[] args)
{
WorkflowDbContext db = new WorkflowDbContext();
var workflowFromDb = db.Workflows.Find("1");
string workFlowDefinition = workflowFromDb.WorkflowDefinition;
ActivityXamlServicesSettings settings = new ActivityXamlServicesSettings
{
CompileExpressions = true
};
}
</code></pre>
<p>When I try this:</p>
<pre><code>DynamicActivity<int> wf = ActivityXamlServices.Load(new StringReader(workFlowDefinition), settings) as DynamicActivity<int>;
</code></pre>
<p>I get this error:</p>
<pre><code>CacheMetadata for activity 'PeakTriggerActivities.SalesToService' threw 'System.Xaml.XamlObjectWriterException: Cannot create unknown type '{clr-namespace:PeakTriggerActivities}GetTouchPoint'.
</code></pre>
<p>I have also tried this, but wf just becomes a null value in this case:</p>
<pre><code>//Encoding this way since xml file shows utf-16
MemoryStream mStream = new MemoryStream(Encoding.Unicode.GetBytes(workFlowDefinition));
//Also tried LocalAssembly = System.Reflection.Assembly.GetExecutingAssembly() instead of LocalAssembly = typeof(GetTouchPoint).Assembly
DynamicActivity<int> wf = ActivityXamlServices.Load(new XamlXmlReader(mStream, new XamlXmlReaderSettings { LocalAssembly = typeof(GetTouchPoint).Assembly }), settings) as DynamicActivity<int>;
</code></pre>
<p>This is what the workFlowDefinition string contains, and the class called GetTouchPoint is in the same project as this main method in program.cs:</p>

How to connect firebase database to an android studio project where i am using sharedpreference
|
<p>So i am using sharedpreference in a voter app and i want to reset counts so that users can vote again next time</p>
<p>So there are 10 counters with 10 textview
I want at perticular time that counts at zero meaning i want to reset that counts but at perticular time.
So how can i connect this to firebase so that everytime users will vote vote also increase in firebase database and at perticular time like 12 am i will manually update that value on zero so users can bote again for the same thing.</p>

<p>The second one gets the desired output by commenting out second <code>CommonProperties</code> embed.</p>
<p>I don't understand why an embed w/ this type of ambiguity would prevent JSON serialization. Is there a solution that doesn't involve writing a bunch of <code>MarshalJSON()</code> functions?</p>

Capybara Poltergeist getting forced over https when using path helpers
|
<p>Poltergeist is unable to connect to the server. Here's the error I'm getting:</p>
<pre><code> Failure/Error: visit root_path
Capybara::Poltergeist::StatusFailError:
Request to 'http://127.0.0.1:58638/' failed to reach server, check DNS and/or server status
</code></pre>
<p>I've got the phantomjs debug output on, and here's what looks like the relevant lines to me:</p>
<pre><code>2016-12-14T14:24:47 [DEBUG] WebpageCallbacks - getJsConfirmCallback

</code></pre>
<p>This bit seemed like a clue <code>Network - Resource request error: QNetworkReply::NetworkError(ConnectionRefusedError) ( "Connection refused" ) URL: "https://127.0.0.1/"</code> and that it could be an ssl error, so I added the phantomjs option <code>--ignore-ssl-errors=true</code>, but it makes no difference to the response.</p>
<p>I switched over to <code>capybara-webkit</code> to see if that would provide a bit more info as some people have recommended. I get a very similar error:</p>
<pre><code>"Visit(http://127.0.0.1:64341/)" started page load

</code></pre>
<p>With the help of @thomas-walpole I realised that if I specific a non-https url to visit in capybara, it works. E.g <code>visit "http://localhost:3000"</code> it works. Using <code>visit root_url</code> works, but using <code>visit root_path</code> I get directed to https and the error above.</p>
<p><code>config.force_ssl</code> is not true. I've set <code>config.force_ssl = false</code> in <code>config/environments/test.rb</code> and also used pry to check the <code>Application.config</code> in the context of the test.</p>
<p>Any ideas for why the path helpers are getting sent over https would be greatly appreciated.</p>

Angular -fill one column based on server response
|
<p>I'm new to angular so sorry if this is a very basic question.</p>
<p>I built a client-server app, that allows to upload files, then validates them (some internal rules) and returns log file in case the validation failed.</p>
<p>I'm using <a href="https://github.com/nervgh/angular-file-upload" rel="nofollow">Angular File Upload</a> module for the client side, the <a href="https://github.com/nervgh/angular-file-upload/tree/master/examples/simple" rel="nofollow">simple</a> example.</p>
<p>The response from server looks like this (JSON)</p>
<pre><code>{"status":"FAILED","entity":"download/logs/24f307d3-8964-4a5b-8d66-0763503892b1/","errors":[]}
</code></pre>
<p>What I want to do is to upload the download link (from response.entity) for every file.</p>
<p>What I get is same link for all files (the one from the last file)</p>
<p>When I check what is happening in debug mode (F12) I do see that the parameters are changing but somehow they are being overridden with the last one.</p>
<p>I think that I have to use ng-repeat somehow, but the thing is that it is already being used for other columns.</p>
<p>Please help.</p>
<p>MY html table:</p>
<pre class="lang-html prettyprint-override"><code><table class="table">

<td ng-show="uploader.showLog">

<p>I did the following change in the controller.js file:</p>
<pre class="lang-js prettyprint-override"><code>uploader.onCompleteItem = function(fileItem, response, status, headers) {
console.info('onCompleteItem', fileItem, response, status, headers);
var resp = JSON.stringify(response.entity);

this.validationStatus = "Yes";
this.showLog = false;
} else {
this.validationStatus = "No";
this.logURL = resp.replace(/\"/g, "");
this.showLog = true;
}
</code></pre>
<p><strong>The solution:</strong></p>
<p>changes in controllers.js file:</p>
<pre class="lang-js prettyprint-override"><code>uploader.onCompleteItem = function(fileItem, response, status, headers) {
console.info('onCompleteItem', fileItem, response, status, headers);
if (response.status === 'FAILED') {
fileItem.validationStatus = "No";
fileItem.logUrl = response.entity;
fileItem.showLog = true;
} else {
fileItem.validationStatus = "Yes";
fileItem.showLog = false;
}
};
</code></pre>
<p>Changes in html file:</p>
<pre class="lang-html prettyprint-override"><code><td ng-show="item.isSuccess" ng-class="{green: item.validationStatus == 'Yes', red: item.validationStatus == 'No'}">
{{item.validationStatus}}
</td>
<td ng-show="item.showLog">
<a href={{item.logUrl}} target="_blank">Log</a>

MooseX::Types and coercion error
|
<p>As continue of <a href="https://stackoverflow.com/a/19624694/1515483">this answer</a> wow im fighting with the my own Moose "type library" - so trying to use "<a href="https://metacpan.org/pod/MooseX::Types" rel="nofollow noreferrer">MooseX::Types</a>".</p>
<p>Based on the above <code>MooseX::Types</code> docs, and "hoobs" comment to the above answer, I defined my own "types" as next:</p>
<pre><code>package MyTypes;
use 5.016;
use Moose;
use MooseX::Types -declare => [qw( Dir File )];
use MooseX::Types::Moose qw( Str );
use Path::Class::Dir;
use Path::Class::File;
class_type Dir, { class => 'Path::Class::Dir' };
coerce Dir, from Str, via { Path::Class::Dir->new($_) };
class_type File, { class => 'Path::Class::File' };
coerce File, from Str, via { Path::Class::File->new($_) };
1;
</code></pre>
<p>and used it in my package</p>
<pre><code>package MyDir;
use Moose;
use warnings;
use MyTypes qw(Dir); #to get the Dir type and its coercion
has 'path' => (
is => 'ro',
isa => Dir, # Dir is defined in the package MyTypes
required => 1,
);
1;
</code></pre>
<p>and tried with the next short script</p>
<pre><code>use 5.016;
use warnings;
use MyDir;
my $d = MyDir->new(path => "/tmp");
</code></pre>
<p>Error:</p>

<p>So, doesn't accept the 'Str' and don't do the coercion.</p>
<p>What is wrong in the above few lines? I'm pretty sure than it is really very small bug, <em>because i followed the MooseX::Types docs</em> (at least i hope) - but unable to find the error. </p>
<p>I'm starting be really hopeless with Moose, please HELP...</p>
<p>Ps: My goal is defining all my own "types" in one place (package) and use it everywhere where i need them with one single "use...".</p>

Can't set propertys of objects in an ObservableList

<p>In my main class I initialise a static object (lkw), which contains the public ObservableList (ladung). Now I want to manipulate the data in the list whith the methode ergebniss, which is located in the class Methoden. I call the methode ergebniss in my JavaFx Gui. It doesn't work. I don't get an error, but the X property is empty. Also removing an element (<code>Main.lkw.ladung.remove(j)</code>) doesn't work.

data_GAN Logistic Regression in R

<p>I've been reading about logistical regression in R. It makes sense when there are columns/variables that actually mean something. My columns are A, B, and C. Column C has only 1's and 0's. How am I to do a regression with such a limited dataset? Any guidance or resources to read would be appreciated.</p>

Filter results, slow performance Swift

<p>Swift question...
I'm making a babyname app and trying to filter the results as chosen by the user. I managed to get it working, but it takes a while for the results to get filtered. I mean like 2-3 seconds.</p>

newList = newList.filter({!spanishboy.contains($0)})
newList = newList.filter({!spanishgirl.contains($0)})
}
}
return newList
}
</code></pre>
<p>So I save the users preferences as a Boolean value in an array called "allSavedSettings" with userdefaults. Whenever a setting is false it will filter the result from the complete list of names.</p>
<p>Is there something else I should use, to speed things up? The list is about 5000 names.</p>
<p>Thanks in advance.</p>

spring google oauth2 return no access_token
|
<p>I'm trying to implement OAuth2 with Google in my Spring Boot application and when I retrieve the Principle object, what I get is given at the last.</p>
<p>Here is the method,that I use to retrieve the user:</p>
<pre><code>@GetMapping("/user")
public Principal user(Principal user) {
return user;
}
</code></pre>
<p>In the response I can find no <em>access_token</em> or something, although I find <em>hash of it</em> and <em>id_token</em>.</p>
<p>So how can I retrieve it ?</p>

<p>I reviewed the Makefile detail, and really could not find any rule to make the target 'libpythonXXX.a'. I googled around, and it seemed that no one had encountered the same issue as me?</p>
<p>In the Makefile, it really has a rule for making the target 'libpythonXXX.so'.</p>

</code></pre>
<p>When I submit the form, the URL loses the "#" and messes it up, and that's no good because the query doesn't work on the secondary website, as it becomes:</p>
<p><a href="http://example.com/rezervari/index.html?hotel=14315&roomtypegroups=44332&from=2020-11-23&to=2020-11-24&roomscount=1&adult=1#/hotelbooking" rel="nofollow noreferrer">http://example.com/rezervari/index.html?hotel=14315&roomtypegroups=44332&from=2020-11-23&to=2020-11-24&roomscount=1&adult=1#/hotelbooking</a></p>
<p>Instead, it should be:</p>
<p><a href="http://example.com/rezervari/index.html#/hotelbooking?hotel=14315&roomtypegroups=44332&from=2020-09-91&to=2020-09-14&adult=1&numchild1=1&numchild2=1&numchild3=1" rel="nofollow noreferrer">http://example.com/rezervari/index.html#/hotelbooking?hotel=14315&roomtypegroups=44332&from=2020-09-91&to=2020-09-14&adult=1&numchild1=1&numchild2=1&numchild3=1</a></p>
<p>How can I pass on the link without the "#" getting removed and the whole URL messed up? Thanks!</p>

<p>I know I am struggling in this problem.
I am working on a webpack Universal React App but i got this error message and I have no idea where it come from:</p>

<p>I think it is because of the url on the eval argument:</p>

<p>Having a relative path in the middle of the url is not good.

Error: "Only unicode objects are escapable. Got None of type <class 'NoneType'>". Could someone please help me spot the mistake(s) in my code?
|
<p>I am a beginner at Twitter Development and Python programming in general, but recently I have been trying to build a bot that, when tagged in reply to a Tweet, finds keywords and uses Google to deliver some info from reliable sources regarding the topic of the original Tweet. However, I have encountered one major problem while programming: <code>API</code> doesn't get created since the code triggers the error "only unicode objects are escapable". I have used module Config to set my Twitter API credentials as environmental variables and that seems to work fine on its own. Before trying to run the bot, I activate my virtual environment and export the env variables, so I do not think this issue has to do with incorrectly setting those variables, but I would not say I am certain about that either!
The code goes this way:</p>
<pre><code>import tweepy

<p>I know it is pretty long but I just wanted to know if anyone could tell me which direction to go with the bug-solving process, since I am kind of lost and I did not know where else to ask! Thank you in advance and sorry for how long this is!!!!<3</p>

Incrementing Variable in v-for Loop by Amount Returned from Method
|
<p>I have a table that uses v-for to loop through an object of days returned from using axios. I've given the ability to manipulate a variety of booleans on each row which change some calculated values in some columns. What I need is to calculate the total of these columns in a bottom row accounting for changes from the values in the rest of the table.</p>
<p>I've tried calling on a method to do something like this.total.b2cTotal += someNumber; but it bugs out the page.</p>

Label caption changes only once
|
<p>I am trying to print out a table into a sheet which has an image with some activex labels on it. As the pages change, I want the label captions to change too and reflect the data in the table. But what is happening is that only the first page is getting printed and the others are not. My MsgBox seems to get the right data but during printing it is just printing the first page. Is it even possible to print out sheets within a for loop? I tried to run the code one page number at a time and it prints out just fine. But when I am looping through page numbers, it prints out only the first page over and over again. </p>
<p>Here's my code. </p>

Failure in arp poisoning python (linux)
|
<p>Okay, so I'm running Ubunutu 14.04 LTS, and I'm trying to poison my own ARP Cache, by doing this,</p>
<p>my private IP address is <strong>10.0.0.1</strong>.</p>
<p>My phone's private IP address is <strong>10.0.0.8</strong>.</p>
<p>for this example only let's say my MAC address is <strong>axaxaxaxaxax</strong>.</p>
<p>I've wrote the following python code:</p>
<pre><code>from binascii import *
from struct import *
import socket;
class ethernetframe:
def __init__(self, destmac, srcmac, ethrtype):
self.destmac = unhexlify(destmac)
self.srcmac = unhexlify(srcmac)
self.ethrtype = unhexlify(ethrtype)
def uniteframe(self, payload):
frame = ''
frame = frame + self.destmac
frame = frame + self.srcmac
frame = frame + self.ethrtype
frame = frame + payload
frame = frame + unhexlify("00000000")
return frame
class arppacket:
def __init__(self,opcode,srcmac,srcip,dstmac,dstip):
if opcode == 1:
dstmac = "000000000000"
opcode = "0001"
else:
opcode = "0002"
self.opcode = unhexlify(opcode)
self.srcmac = unhexlify(srcmac)
self.srcip = pack('!4B',srcip[0],srcip[1],srcip[2],srcip[3])
self.dstmac = unhexlify(dstmac)
self.dstip = pack('!4B',dstip[0],dstip[1],dstip[2],dstip[3])
def unitepacket(self):
packet = ''
packet = packet + "\x00\x01\x08\x00\x06\x04"
packet = packet + self.opcode
packet = packet + self.srcmac
packet = packet + self.srcip
packet = packet + self.dstmac
packet = packet + self.dstip
return packet
e1 = ethernetframe("axaxaxaxaxax","axaxaxaxaxax","0800")
arp1 = arppacket(2,"axaxaxaxaxax",(10,0,0,8),"axaxaxaxaxax",(10,0,0,1))
arpacket = arp1.unitepacket()
fullethframe = e1.uniteframe(arpacket)
s = socket.socket(socket.AF_PACKET,socket.SOCK_RAW,socket.htons(0x0806))
s.bind(("eth0",0))
s.send(fullethframe)
</code></pre>
<p>now, I'm monitoring this whole process with Wireshark, the ARP packet is being send and it is formed correctly, In wire shark I see the following line:</p>
<p><strong>10.0.0.8 is at axaxaxaxaxax</strong></p>
<p>This means that I have successfully sent an ARP reply! to my own computer, stating that the MAC address that is resolved for <strong>10.0.0.8</strong> is <strong>axaxaxaxaxax</strong>
since ARP cache automatically update if a reply is received REGARDLESS if a request was sent, this means that in my NIC driver's arp cache there should've been a line added stating that
<strong>10.0.0.8 is resolved with axaxaxaxaxax</strong></p>
<p>however, when I run inside my ubunutu's terminal </p>
<pre><code>arp - a
</code></pre>
<p>or </p>
<pre><code>arp - an
</code></pre>
<p>it doesn't show up....., which means I've failed to poison my own ARP cache, any ideas how to fix this?</p>

Laravel sync users to all of categoires which they can be unlimited
|
<p>In our web application each user can create multiple nested category by selecting the parent which that specified with <code>category_id</code> column.</p>
<pre class="lang-php prettyprint-override"><code>Schema::create('categories', function (Blueprint $table) {
$table->bigIncrements('id');
$table->unsignedBigInteger('category_id')->index()->nullable();
$table->foreign('category_id')->references('id')->on('categories')->onDelete('cascade');
$table->string('category_name');
...
$table->timestamp('created_at')->useCurrent();
$table->timestamp('updated_at')->useCurrent();
});
</code></pre>
<p>now you supposed one of our user created this category structure:</p>
<p><a href="https://i.stack.imgur.com/3xjXo.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3xjXo.png" alt="enter image description here" /></a></p>
<p>multiple nested categories children are unlimited, that means every category can be have child and we can't use any static or fixed number for example in <code>for</code> statement to sync the category to specify <code>users</code>.</p>
<p>my question is how can i set specify <code>users</code> to all of categories from parent?</p>
<p>this query only can set users for single child of parent. you can suppose <code>1</code>,<code>3</code>,<code>4</code>,<code>5</code>,<code>6</code>,<code>7</code> in above screen shot and not working for <code>2</code> and all of their children</p>
<p>children of <code>parent category</code> can be unlimited and how can we set <code>users</code> from the parent to all of nested and children categories?</p>
<pre class="lang-php prettyprint-override"><code>$category = Category::whereId($request->category_id)->whereNull('category_id')->with('childrenCategories')->first();
$category->users()->sync($request->users);
foreach ($category->childrenCategories as $category) {
$category->users()->sync($request->users);
}
</code></pre>
<p>simplified output of query:</p>
<pre><code>App\Entities\Category {#2114 ▼
...
#attributes: array:11 [▶]
#original: array:11 [▶]
...
#relations: array:1 [▼
"childrenCategories" => Illuminate\Database\Eloquent\Collection {#2118 ▼

Pareto front for matplotlib scatter plot
|
<p>I'm trying to add pareto front to scatter plot I have. The scatter plot data is:</p>
<pre><code>array([[1.44100000e+04, 3.31808987e+07],
[1.21250000e+04, 3.22901074e+07],
[6.03000000e+03, 2.84933900e+07],
[8.32500000e+03, 2.83091317e+07],
[6.68000000e+03, 2.56373373e+07],
[5.33500000e+03, 1.89331461e+07],
[3.87500000e+03, 1.84107940e+07],
[3.12500000e+03, 1.60416570e+07],
[6.18000000e+03, 1.48054565e+07],
[4.62500000e+03, 1.33395341e+07],

[5.45000000e+02, 5.66882578e+06]])
</code></pre>
<p>and the the scatter plot looks like this:</p>
<p><a href="https://i.stack.imgur.com/4JMzG.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4JMzG.png" alt="enter image description here" /></a></p>
<p>I have used this <a href="https://pythonhealthcare.org/tag/pareto-front/" rel="nofollow noreferrer">tutorial</a> in order to plot the pareto, but for some reason the result is very weird and I get tiny red line :</p>
<p><a href="https://i.stack.imgur.com/ARmog.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ARmog.png" alt="enter image description here" /></a></p>
<p>This is the code I have used:</p>
<pre><code>def identify_pareto(scores):
# Count number of items
population_size = scores.shape[0]
# Create a NumPy index for scores on the pareto front (zero indexed)
population_ids = np.arange(population_size)
# Create a starting list of items on the Pareto front
# All items start off as being labelled as on the Parteo front
pareto_front = np.ones(population_size, dtype=bool)
print(pareto_front)
# Loop through each item. This will then be compared with all other items
for i in range(population_size):
# Loop through all other items
for j in range(population_size):
# Check if our 'i' pint is dominated by out 'j' point
if all(scores[j] >= scores[i]) and any(scores[j] > scores[i]):
# j dominates i. Label 'i' point as not on Pareto front
pareto_front[i] = 0
# Stop further comparisons with 'i' (no more comparisons needed)
break
# Return ids of scenarios on pareto front
return population_ids[pareto_front]
pareto = identify_pareto(scores)
pareto_front_df = pd.DataFrame(pareto_front)
pareto_front_df.sort_values(0, inplace=True)
pareto_front = pareto_front_df.values
#here I get as output weird results:
>>>
array([[ 5, 81],
[15, 80],
[30, 79],
[55, 77],
[70, 65],
[80, 60],
[90, 40],
[97, 23],
[99, 4]])
x_all = scores[:, 0]
y_all = scores[:, 1]
x_pareto = pareto_front[:, 0]
y_pareto = pareto_front[:, 1]
plt.scatter(x_all, y_all)
plt.plot(x_pareto, y_pareto, color='r')
plt.xlabel('Objective A')
plt.ylabel('Objective B')
plt.show()
</code></pre>
<p>the result is the tiny red line.</p>
<p>My question is, where is my mistake? how can I get back the pareto line?</p>

Reading YUY2 data from an IMFSample that appears to have improper data on Windows 10
|
<p>I am developing an application that using IMFSourceReader to read data from video files. I am using DXVA for improved performance. I am having trouble with one specific full-HD H.264 encoded AVI file. Based on my investigation this far, I believe that the IMFSample contains incorrect data. My workflow is below:</p>
<ol>
<li>Create a source reader with a D3D manager to enable hardware acceleration.</li>
<li>Set the current media type to YUY2 as DXVA does not
decode to any RGB colorspace. </li>
<li>Call ReadSample to get an IMFSample. Works fine.</li>
<li>Use the VideoProcessorBlt to perform YUY2 to BGRA32
conversion. For this specific file it errors out with an
E_INVALIDARGS error code. Decided to do the conversion myself. </li>
<li>Used IMFSample::ConvertToContiguousBuffer to receive an IMFMediaBuffer. When locking this buffer, the pitch is reported as 1280 bytes. This I believe is incorrect, because for a full HD video, the pitch should be (1920 + 960 + 960 = 3840 bytes).</li>
</ol>
<p>I dumped the raw memory and extracted the Y, U and V components based on my understanding of the YUY2 layout. You can find it below. So, the data is there but I do not believe it is laid out as YUY2. Need some help in interpreting the data.</p>

show data linked to logged in user and custom database email address

<p>I'm new to coding and I need a little help, please</p>
<p>I need logged in user on WordPress(website) linked to my custom DB via email address to show data from my custom DB, like a company, address, etc etc for the logged in user only</p>
<p>I've managed to get the data from the custom DB to display and logged in user info to display too(this part is so i can see logged in info), with the code below</p>
<p>I guess there must be a way of doing this and would I need to have a relationship in DB tying user email and customer email</p>
<p>any help would be much appreciated</p>
<p>thank you for your time</p>

<p>I now get the results from email addresses that are the same in both tables, but I just require the logged in user to be displayed, how can i do that?</p>
<pre><code> <?php

Unable to run Tensorflow Data Validation on Google Cloud Platform (Dataflow)

<p>I have been trying to run TensorFlow Data Validation following Google Documents</p>
<p>Followed same steps as <a href="https://www.tensorflow.org/tfx/data_validation/install" rel="nofollow noreferrer">https://www.tensorflow.org/tfx/data_validation/install</a>:</p>

<p><code>>sudo docker-compose build manylinux2010</code></p>
<p><code>>sudo docker-compose run -e PYTHON_VERSION=${PYTHON_VERSION} manylinux2010</code></p>
<p>Updated with proper path</p>
<pre><code>import tensorflow_data_validation as tfdv

elasticsearch bool filter should clause performance

<p>first query:</p>
<pre><code> { "query" : {

]
}
}
}
}
</code></pre>
<p>In relational SQL, the first query equals to SQL:</p>
<pre><code>select * from table where user1_id =1 and (day>=2015-04-01 and day <= 2015-04-30)
</code></pre>
<p>Second query:</p>
<pre><code>{ "query" : {

<p>The difference is, </p>
<p>the first query only considers <code>user1_id</code>, while the second one also check <code>user2_id</code>.</p>
<p>both <code>user1_id</code> and <code>user2_id</code> are indexed.</p>
<p>However, the performance differs a lot. </p>
<p>the first query took 5 seconds, while the second one took 20 seconds.</p>
<p>Is there any better way for the second query?</p>

<pre><code> user1_id:

doc_values: true
day:

format: "YYYY-MM-dd"
ignore_malformed: true
doc_values: true
</code></pre>
<p>If I run the first query twice, the first time is <code>user1_id</code>, the second time is <code>user2_id</code>, then combine two results. It is much faster than using the second query. </p>

Vega plot not displaying within a holoviz panel in jupyter notebook
|
<p>I find the <a href="https://github.com/holoviz/panel" rel="nofollow noreferrer">holoviz panel</a> a very interesting solution to building data visualisation dashboards. Unfortunately, I have some issues getting a vega plot of a node-link diagram to work within a panel in a jupyter notebook.</p>
<p>The relevant imports etc:</p>
<ul>
<li><code>import panel</code></li>
<li><code>pn.extension()</code></li>
<li><code>from vega import Vega</code></li>
</ul>
<p>My findings:</p>
<ul>
<li>The vega import works nicely when used outside of a panel: the Vega specification copy/pasted from <a href="https://vega.github.io/editor/#/examples/vega/force-directed-layout" rel="nofollow noreferrer">https://vega.github.io/editor/#/examples/vega/force-directed-layout</a> is visualised as it should be using <code>Vega(spec)</code> (see screenshot 1).</li>
<li>When using <code>pn.pane.Vega(spec)</code> I get an empty space. Running the visualisation externally using <code>pn.pane.Vega(spec).show()</code> and looking at the source code, I see that the div is empty (see screenshot 2).</li>
</ul>
<p>Any help with getting this working much appreciated...</p>
<p>Thank you,
jan.</p>

How do you delete an Item from a ListView from a dialog box class?

<p>I made my own dialog box class. This class has a button to delete an item from a listview(which is the main acctivity_main.xml). When I push the delete button the item does not get deleted. </p>
<p>I have seen this topic <a href="https://stackoverflow.com/questions/4698386/android-how-to-remove-an-item-from-a-listview-and-arrayadapter">Android: how to remove an item from a listView and arrayAdapter</a>. It just appears the user does not know how to get the item index correctly, which I believe I have done correctly.</p>
<p><a href="https://stackoverflow.com/questions/2558591/remove-listview-items-in-android">Remove ListView items in Android</a> This one is pretty close. But in my code I created my own dialog, this one is using a positive and negative button. I am passing variables between my dialog class and to the mainActivity. </p>
<p>my onClickListener in OnCreate withing the MainActivity</p>
<pre><code> mFoodDataAdapter = new FoodDataAdapter();
final ListView listFoodData = (ListView) findViewById(R.id.listView);
listFoodData.setAdapter(mFoodDataAdapter);
//Handle clicks on the ListView
listFoodData.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapter, View view, int whichItem, long id) {
FoodData tempFoodData = mFoodDataAdapter.getItem(whichItem);
//create a new dialog window
DialogShowFood dialog = new DialogShowFood();
// send in a reference to the note to be shown
dialog.sendFoodDataSelected(tempFoodData);
FoodDataAdapter adapter1 = new FoodDataAdapter();
/*this is where i send the data to the DialogShowFood.java*/
dialog.sendFoodDataAdapter(adapter1, whichItem);
// show the dialog window with the note in it
dialog.show(getFragmentManager(),"");
}
});
</code></pre>
<p>Here is my class for the dialog "DialogShowFood.java"</p>
<pre><code>public class DialogShowFood extends DialogFragment {
FoodData mFood;
MainActivity.FoodDataAdapter mAdapter;
int mitemToDelete;
@Override
public Dialog onCreateDialog(Bundle savedInstanceState){
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View dialogView = inflater.inflate(R.layout.dialog_show_food, null);
Button btnDelete = (Button) dialogView.findViewById(R.id.btnDelete);
builder.setView(dialogView).setMessage("Your food");
/*this sends the item to delete to the adapter*/
btnDelete.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mAdapter.deleteFoodData(mitemToDelete);
dismiss();
}
});
return builder.create();
}
/*this gets the data to delete from the MainActivity*/
public void sendFoodDataAdapter(MainActivity.FoodDataAdapter adapter1, int whichItem) {
mAdapter = adapter1;
mitemToDelete = whichItem;
}
}
</code></pre>
<p>The function inside the adapter</p>
<pre><code> /*this is the function in the base adapter to delete the item*/
public void deleteFoodData(int n){
Toast.makeText(MainActivity.this,Integer.toString(n), Toast.LENGTH_SHORT).show();
foodDataList.remove(n);
notifyDataSetChanged();
}
</code></pre>
<p>The Toast outputs the proper indexes of the item to delete, it just does not delete the item for some reason. </p>

Customized Windows 10 Backup not porting well
|
<p>So basically I customized a Windows 10 install. I have the PerfLogs, Program Data, Temp and Users folders in C:\ replaced as symlinks to their actual location to D:\</p>
<p>The purpose being, I will only keep a image backup of C:\ and when the need arises that I need a fresh install of the OS, I will only overwrite the whole C: drive with the backup and don't even have to touch my old user profiles. It works without a glitch even as I moved my C: to an SSD.</p>
<p>I did it with a few simple tricks (I don't exactly remember everything I did, but once I got the build right, I just left it as it is as I thought I would never have to touch it again):</p>
<ol>
<li><p>I remembered following tips and other guides like this:</p>
<p><a href="https://commaster.net/content/windows-installation-tips-moving-user-folder-another-drive" rel="nofollow">https://commaster.net/content/windows-installation-tips-moving-user-folder-another-drive</a></p>
<ul>
<li>the difference being I used symlinks instead of junctions with mklink command.</li>
</ul></li>
<li><p>Some modification with registry and other files.</p></li>
<li>Several stages of booting until everything has been transferred and having windows re-create the profiles and configurations.</li>
</ol>
<p>Anyways, I had to fix my Mom's PC, which was in a state of disarray as she thought she had to save all her files in C:\ and NEVER in Documents. I opted to install my customized Windows install, so if I need to fix it again, it would just be a cinch.</p>
<p>Before building this custom Windows install, I've made backups of my system with my usual backup tool, Paragon Partition Manager. They worked fine and when I had to change PC builds, such as changing my motherboard, all I had to do was change the drivers. So I thought with my custom Windows 10 install, that's all I had to do for my Mom's PC.</p>
<p>But I kept running into problems with Window's User Profile Service.
At first, it was having difficulty loading the Administrator account and seems to be defaulting to C:\Windows\System32\config\systemprofile, as it cannot seem to write to it's D:\Users\Administrator folder. I quickly fixed that, but, still, it can't load the Start Menu and other services. </p>
<p>The only one that was working <em>almost</em> completely was the user (just one - me) that was existing when I created the backup AND only works with a copy of the corresponding folder in D:\Users\<em>MyUsername</em>.</p>
<p>Obviously I wanted to create a user just for my Mom and one that is <em>completely</em> working and I don't wanna leave a copy of D:\Users\<em>MyUsername</em> in her PC. I figured all I had to do was create a user profile in Control Panel and Windows will recreate everything and all the configurations. The add user service in Control Panel wasn't working with Administrator, but only with <em>MyUsername</em>. But whenever I try to sign in to the newly created user, the "User Profile Service failed to sign-in" keeps popping up. I can sign into it in safe mode, at the first seemingly recreating everything with the first-time-sign-in-welcome-screen, but a lot of the services are not working. So creating another user profile with this new profile doesn't work. </p>
<p>More notably, I've tried:</p>
<pre><code>net user username /add
</code></pre>
<p>and adding through advanced user profiles:</p>
<pre><code>control userpasswords2
</code></pre>
<p>But the new registry keys for the new users in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList never gets created -- even after I go safe mode and manage to sign in to the new users.</p>
<p>I've also considered it might be a user permission issue, somehow being carried over from my PC build (if that makes sense, it still doesn't to me). Anyways, so with the newly created user logged in with safe mode, I tried changing permission for C: and D: for every single group to "Full Control". Then from that newly created user, create another user either through <code>net user username /add</code> or <code>control userpasswords2</code>. I even tried booting to Linux LiveCD and chmod-ding everything to 777 (I'm not even sure how that transfer to an NTFS. Then I try to sign in and even if I can forcibly sign in, it just isn't a glitch-free user profile.</p>

Yii: CHtml image link - how to get to the image in one table through relation in other table?
|
<p>I'm trying to display link to an <em>album/view</em> through image that belongs to that album. I have my model 'Album' and there I have the relation with my 'Photo' model, which represents table where pictures are saved(or to be more accurate-picture names, pictures are saved in the folder 'uploads': </p>
<pre><code>public function relations()
{
return array(
'photos' => array(self::HAS_MANY, 'Photo', 'album_id'),
);
}
</code></pre>
<p>Now I'm displaying <em>album/index</em> view, where I parse $dataProvider object which contains all my albums. Now that $dataProvider is parsed to a <em>_view</em> view and there I'm trying to access pictures (actually I just need one picture per album) that belongs to each album displayed. That picture will represent the link to an <em>album/view</em> view where one can see all pictures belonging to that album. I have no ide how to do that. I've tried with: </p>
<pre><code>CHtml::link(
CHtml::image(Yii::app()->request->baseUrl."/uploads/thumbs/".$data->photos->name),
array('view', 'id'=>$data->id));
</code></pre>
<p>and I got the error: <strong>Trying to get property of non-object</strong></p>
<p>PS: I have no problem with displaying all pictures within one album in <em>album/view</em> view (but these cross controllers, cross table whatever things are giving me hard time). There I have nested <em>photo/index</em> view, and the pictures are displayed like this: </p>
<pre><code>echo CHtml::link(
CHtml::image(Yii::app()->request->baseUrl."/uploads/thumbs/".$data->name),
Yii::app()->request->baseUrl."/uploads/".$data->name ),
</code></pre>
<p>(as a link I'm displaying thumbnail of an image, that why i have "/uploads/thumbs/". "name" is column in table which represents filename of an image)</p>

Why are the buttons inside the UIView squashed to the top?

<p>I have installed the <code>ABVideoRangeSlider</code> pod into my project,
it all works fine besides that the start, end and progress sliders are squashed to the top.
Here's my code:</p>

Docker Swarm load balancing or mesh routing issue
|
<p>I have a single docker node configured as a docker swarm.</p>
<p>I have created an overlay network called main_net which uses encryption.</p>
<p>I have mutiple containers connected to this network. One of which is called kong and runs kong. I have a service called saas_thumbsum_0_0_13 - this has a single container running inside it. </p>
<p>Kong is configured as a reverse proxy for saas_thumbsum_0_0_13, and uses the address saas_thumbsum_0_0_13. This setup was working this morning when I had a service called saas_thumbsum_0_0_12 running, Kong was sending requests to <a href="http://saas_thumbsum_0_0_12:80/public" rel="nofollow noreferrer">http://saas_thumbsum_0_0_12:80/public</a> without a problem.</p>
<p>I have now created another service 0_0_13 and connected it to the network but kong can not access <a href="http://saas_thumbsum_0_0_13:80/public" rel="nofollow noreferrer">http://saas_thumbsum_0_0_13:80/public</a></p>
<p>I have logged into the console of the kong container and ran the following commands:</p>
<pre><code>/ # nslookup saas_thumbsum_0_0_13
nslookup: can't resolve '(null)': Name does not resolve
Name: saas_thumbsum_0_0_13
Address 1: 10.0.0.39
/ # nslookup tasks.saas_thumbsum_0_0_13
nslookup: can't resolve '(null)': Name does not resolve
Name: tasks.saas_thumbsum_0_0_13
Address 1: 10.0.0.40 d4c3034462d1.main_net
</code></pre>
<p>so the service resolves to 10.0.0.39 which I guess is the load balanced ip, and the service has one task with an ip of 10.0.0.40. Seems ok so far.
Now I try and ping the two ip's from inside the kong container:</p>
<pre><code>/ # ping 10.0.0.39
PING 10.0.0.39 (10.0.0.39): 56 data bytes
64 bytes from 10.0.0.39: seq=0 ttl=64 time=0.089 ms
64 bytes from 10.0.0.39: seq=1 ttl=64 time=0.083 ms
^C
--- 10.0.0.39 ping statistics ---
2 packets transmitted, 2 packets received, 0% packet loss
round-trip min/avg/max = 0.083/0.086/0.089 ms
/ # ping 10.0.0.40
PING 10.0.0.40 (10.0.0.40): 56 data bytes
64 bytes from 10.0.0.40: seq=0 ttl=64 time=0.146 ms
64 bytes from 10.0.0.40: seq=1 ttl=64 time=0.091 ms
^C
--- 10.0.0.40 ping statistics ---
2 packets transmitted, 2 packets received, 0% packet loss
round-trip min/avg/max = 0.091/0.118/0.146 ms
</code></pre>
<p>I can successfully ping both IP addresses. This seems fine to me as from my beginner level knowldege they should load balance to the same endpoint and the results should not differ.</p>
<p>Now if I try and get the webpage from the load balanced ip it fails:</p>
<pre><code>/ # wget 10.0.0.39/public/web/frontend
Connecting to 10.0.0.39 (10.0.0.39:80)
wget: can't connect to remote host (10.0.0.39): Connection refused
</code></pre>
<p>Same if I use the service name</p>
<pre><code>/ # wget saas_thumbsum_0_0_13/public/web/frontend
Connecting to saas_thumbsum_0_0_13 (10.0.0.39:80)
wget: can't connect to remote host (10.0.0.39): Connection refused
</code></pre>
<p>same with and without http://</p>
<p>but it works if I go to the task ip:</p>
<pre><code>/ # wget 10.0.0.40/public/web/frontend
Connecting to 10.0.0.40 (10.0.0.40:80)
Connecting to 10.0.0.40 (10.0.0.40:80)
frontend 100% |*******************************************************| 1769 0:00:00 ETA
</code></pre>
<p>But I should be using the service endpoint not the task endpoint!</p>
<p>If the address is load balanced then they both should go to the same target so the result should be the same.</p>
<p>The target container is running nginx and I have checked the config files there but I don't see any kind of source ip restriction. Not sure how I would do this anyway because the ip addresses would be different every time anyway!</p>
<p>So this is broken, wget saas_thumbsum_0_0_13/public/web/frontend should be giving me the page but it is not working.</p>
<p>If anyone can spot my mistake or give me any debugging pointers it would be appreciated.</p>
<p>Some other info that might be helpful:</p>

I do not get any exception or error, they just never reach the address, or go to Spam/Junk.
When i synchronize my 'Sent' folder, the e-mail appears.</p>
<p>The code i am using to send e-mails is below </p>
<pre><code> var smtpClient = new System.Net.Mail.SmtpClient(hostName)
{
EnableSsl = false,
DeliveryMethod = SmtpDeliveryMethod.Network

smtpClient.Credentials = new NetworkCredential(userName, password);
smtpClient.SendAndSaveMessageToIMAP(mailMessage, hostName, port, userName, password, "INBOX.Sent");

Bootstrap menu won't close on touch devices
|
<p>Pulling my hair out trying to get this working.
Responsive menu works fine when browser is scaled down to mobile size, ie, clicking a link closes the menu and page scrolls to correct section. When I enable touch emulation however in Google dev tools, I can see that data-toggle="collapse" is not being fired, so menu stays open upon click. Now, here's the thing, I bought a theme and there is a fair bit of extra js written by whoever created it that is more than likely causing the issue. Theme is no longer supported so I'm really stuck.</p>
<p>My menu code:</p>
<pre><code><div class="header" id="header">
<div class="navbar-wrapper" id="navigation" role="navigation">
<div class="navbar navbar-inverse">
<div class="container">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#navbar-collapse-down">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand brand-container " href="#home" title="CandyPOP!" rel="home" id="brand" > <img src="img/logocp1bcolour2.png" alt="CandyPOP logo" class="firstb" width="160">
<!-- logo to display on scrolling -->
<img src="img/logocp1bcolour2.png" alt="CandyPOP logo" class="last" width="160"> </a>
<div class="navbar-collapse collapse" id="navbar-collapse-down">
<ul id="nav" class="nav navbar-nav">
<li class ="active"><a href="#home" data-spy="#home" data-toggle="collapse" data-target="#navbar-collapse-down">Home<span></span></a></li>
<li><a href="#portfolio" data-spy="#portfolio" data-toggle="collapse" data-target="#navbar-collapse-down">Line Up<span></span></a></li>
<li><a href="#tickets" class="menu-item" data-spy="#tickets" data-toggle="collapse" data-target="#navbar-collapse-down">Tickets<span></span></a></li>
<li><a href="#blog" class="menu-item" data-spy="#blog" data-toggle="collapse" data-target="#navbar-collapse-down">News<span></span></a></li>
<li><a href="#contact" data-spy="#contact" data-toggle="collapse" data-target="#navbar-collapse-down">Contact<span></span></a></li>
</ul>
</div>
</div>
</div>
</div>
</div>
</code></pre>
<p>And here is all menu related js that came with the theme:</p>
<pre><code>var lastId,
topMenuHeight,
topMenu = $('#nav'),
menuItems = topMenu.find('a'),
menuItemsTop = topMenu.find('> li > a'),
scrollItems = menuItemsTop.map(function(){
var item = $($(this).data('spy'));
if (item.length) { return item; }
});
if ($('body').hasClass('leftnav')){
topMenuHeight = 0;
} else {
topMenuHeight = 50;
}
menuItems.not('.external-link').on('click touchend',function(e) {
e.preventDefault();
var target = $(this).attr('href');
if (!$(this).parent().parent().hasClass('dropdown-menu')){
$(this).parent().siblings().removeClass('active');
}
$(this).data('clicked', true);
// If the url item is defined, this for dropdowns
if ( typeof ( $(target).offset() ) !== 'undefined'){
$('html,body').stop().animate({
scrollTop: $(target).offset().top - topMenuHeight
}, '1000' ,'easeOutExpo');
}
});
// Drop down navigation
$('.dropdown-menu li a').click(function(){
var j = $(this).parent().index();
var subnavigation = $(this).closest('ul').data('subnav');
$('#'+ subnavigation + ' li').removeClass('active');
$('#'+ subnavigation + ' li').each(function(i){
if ( j === i){
$(this).addClass('active');
}
})
var target = $('#'+ subnavigation + ' li').closest('.parent');
$('html,body').stop().animate({
scrollTop: target.offset().top - topMenuHeight
}, '1000' ,'easeOutExpo');
})
// Scroll on click links
$('.link-more[href*=#]').click(function(e){
e.preventDefault();
var target = $(this.hash);
$('html,body').stop().animate({
scrollTop: target.offset().top - topMenuHeight
}, '1000' ,'easeOutExpo');
})
// Scroll to the section clicked on navigation
$(window).scroll(function(){
var fromTop = $(this).scrollTop() + topMenuHeight;
var cur = scrollItems.map(function(){
if($(this).offset().top < fromTop + 1)
return this;
});
cur = cur[cur.length-1];
var id = cur && cur.length ? cur[0].id : '';
if (lastId !== id) {
lastId = id;
menuItemsTop
.parent().removeClass('active')
.end().filter("[data-spy=#"+id+"]").parent().addClass("active");
}
})
$('.navbar-toggle').on('click', function(e){
$('.nav').toggle();
});
</code></pre>
<p>I also copied the last couple of lines from the js and changed it to be triggered from .menu-item like this:</p>
<pre><code>$('.menu-item').on('click', function(e){
$('.nav').toggle();
});
</code></pre>
<p>If anyone would be so kind as to help me out I would be very grateful.
Cheers</p>

Why I obtain this exception when I try to handle an AJAX request with a Laravel controller method?
|
<p>I am absolutely new in PHP and Laravel and I have the following problem.</p>
<p>From my view I perform an AJAX <strong>POST</strong> request via JQuery, by this code:</p>
<pre><code>jQuery.ajax({
url: '/doSearch',
type: 'POST',
dataType: 'json',
//data: $form.serialize(),
success: function(data){
console.info('ssssssssssiiii',data);
},
error: function(data, b){
console.info('erroreeeeee');
}
});
</code></pre>
<p>This <strong>POST</strong> request is handled by this simple controller method:</p>
<pre><code>public function doSearch(){
echo 'SEARCHED';
}
</code></pre>
<p>that have to return the view the <strong>SEARCHED</strong> string.</p>
<p>The problem is that I am obtaining this error message:</p>
<pre><code>http://localhost:8000/doSearch 500 (Internal Server Error)
</code></pre>
<p>that is create by this exception casauted by a <strong>TokenMismatchException</strong>, in the Laravel stackrace I can see something like this:</p>

<p>What could be the problem? How can I solve this issue?</p>

(NGINX) NodeJS Reverse Proxy Subdomain
|
<p>This question has probably been asked a lot, but I can't seem to find a really simple solution that actually works. And I need help to set this up.</p>
<p><strong>I'll list my current enviroment so you can get a quick overview:</strong></p>
<ul>
<li>Server Host: HETZNER Cloud Server</li>
<li>Domain Host: Webhuset.no (DNS Records are here)</li>
<li>OS: CentOS 7 (Hetzner)</li>
<li>Website: Running NGINX with NodeJS reverse proxy</li>
<li>DNS: I have not added *.domain.example in my DNS Record, because I don't want every sub-host to to to my server.</li>
<li>SSL: Enabled, using Let's Encrypt Certbot.</li>
</ul>
<p>I am only running one site, with of course, different pages for different stuff (Not multiple sites)</p>
<p>My goal is to have something similar to CPanel-subdomains. Where I can add <strong>admin.domain.example</strong> and set it to for example <strong>domain.example/admin</strong> without redirect.</p>
<p>But I have found this to be harder than expected, because I have been reading so many forum-posts and so many docs now and I just can't get it to work.</p>
<p>I have come far enough to understand that the subdomain has to be configured in Nginx. Before this I kept trying to do this in the nodejs config.</p>
<p>My current <strong>nginx.conf</strong> which makes my domain <strong>example.domain</strong> go straight to root folder of my website, with SSL. This works fine.</p>
<pre><code>user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
server {
server_name example.domain www.example.domain;
include /etc/nginx/default.d/*.conf;
location / {
proxy_pass http://127.0.0.1:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
listen [::]:443 ssl ipv6only=on;
listen 443 ssl;
ssl_certificate /etc/letsencrypt/live/example.domain/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.domain/privkey.pem;
include /etc/letsencrypt/options-ssl-nginx.conf;
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
}
}
</code></pre>
<p>Here I assume I have to add a server block in order to make <strong>admin.example.domain</strong> route to <strong>example.domain/admin</strong></p>
<p>How can I do this and still maintain SSL? I need SSL in order to make the images render.
I have tried adding a server block like this:</p>
<pre><code> server {
server_name admin.example.domain
location / {
proxy_pass http://127.0.0.1:3000/admin;
}
listen [::]:443 ssl ipv6only=on;
listen 443 ssl;
ssl_certificate /etc/letsencrypt/live/example.domain/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.domain/privkey.pem;
include /etc/letsencrypt/options-ssl-nginx.conf;
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
}
</code></pre>
<p>If this were to work <em>(It doesn't unless I listen to port 80 and use http://)</em>, it would just redirect me to <strong>(UNSECURE)<a href="https://admin.example.domain/admin" rel="nofollow noreferrer">https://admin.example.domain/admin</a></strong></p>
<p>And everybody who do the same as I just did above, gets it to work. But I don't. What is different, and how can I solve this?</p>

Elasticsearch dynamic choose query
|
<p>When querying with the should command, I am wondering if there is a way to make only the responses of queries with higher scores come out.</p>
<p>I'm sorry I'm not good at English, please understand it.
Let's assume I have such data</p>
<h3>index</h3>
<pre><code>{
"mappings": {
"properties": {
"name": {
"type": "keyword"
}
}
}
}
</code></pre>
<h3>data</h3>
<pre><code>{
"_index" : "dismisstest",
"_type" : "_doc",
"_id" : "1",
"_score" : 1.0,
"_source" : {
"name" : "chul"
}
},
{
"_index" : "dismisstest",
"_type" : "_doc",
"_id" : "2",
"_score" : 1.0,
"_source" : {
"name" : "wedul"
}
}
</code></pre>
<h3>query (example..)</h3>
<pre><code>GET dismisstest/_search
{
"query": {
"bool": {
"should": [
{
"term": {
"name": {
"value": "wedul",
"boost": 2
}
}
},
{
"term": {
"name": {
"value": "chul",
"boost": 4
}
}
}
]
}
}
}
</code></pre>
<h3>want result (Document using only wedul query)</h3>
<pre><code>{
"_index" : "dismisstest",
"_type" : "_doc",
"_id" : "2",
"_score" : 1.0,
"_source" : {
"name" : "wedul"
}
}
</code></pre>
<p>The above query is a simple example, but I want to use only the query that returns the document with a high score among the two should queries. Is there any possible way??</p>

java ssl hanshake exception
|
<p>I know there has been lots of questions regarding this ssl hand shake, I still could not figure this out.
I am trying to submit a java-ws soap message to <a href="https://demo296.vertexinc.com/vertex-ws/services/CalculateTax70?wsdl" rel="nofollow">link</a> and end point got proper certificate, but why java won't honor it and gives this well known exception:</p>
<pre><code>Caused by: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
</code></pre>
<p>When I enable network debugging, I get following:</p>

<p>As you can see from the end point, cert chain is coming from authority.</p>
<p><a href="http://i.stack.imgur.com/UdA1I.png" rel="nofollow">screenshot</a></p>
<p>GeoTrust Global CA is the root chain and included in default jdk cacerts.
I was thinking if root issuer is trusted and in cacerts then java should honor it, but it did not. Then 2nd cacerts chain GeoTrust SSL CA - G3 is not there and I imported it. Still did not work. I can import the entire cert chain, but why java won't honor trusted authority in this case?</p>
<p>Thank you!</p>

Chrome web app using firebase returns mismatchsenderid error
|
<p>I apologise as this question has been asked many times, but none of the responses have been helpful in resolving my issue.</p>
<p>I am using firebase with my web app and attempting to send notifications via php or terminal curl command. Have tried both with same error:</p>
<blockquote>
<p>{"multicast_id":4984414565388562908,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"MismatchSenderId"}]}</p>
</blockquote>
<p>I am getting the API key and sender id straight from firebase from the same place. Copying and pasting, no typos. Checked about 50 times... 100% sure the sender id matches the API key as i am copying and pasting from the same screen.</p>
<p><a href="https://i.stack.imgur.com/HKmDC.png" rel="nofollow"><img src="https://i.stack.imgur.com/HKmDC.png" alt="Firebase console"></a></p>
<p>I am getting the endpoint from the Chrome console:</p>
<p><a href="https://i.stack.imgur.com/mFPu4.png" rel="nofollow"><img src="https://i.stack.imgur.com/mFPu4.png" alt="Endpoint"></a></p>
<p>Again, copied and pasted with no typos.</p>
<p>My PHP file:</p>
<pre><code><?php
// API access key from Google API's Console
define( 'API_ACCESS_KEY', '**API_KEY**' );
$registrationIds = array('**SUBSCRIPTION_ID**');
// prep the bundle
$msg = array
(
'message' => $_GET["message"],
'title' => $_GET["title"],
'subtitle' => $_GET["subtitle"],
'tickerText' => $_GET["ticker"],
'vibrate' => 1,
'sound' => 1,

'smallIcon' => 'http://www.uidownload.com/files/303/56/11/small-arrow-left-fast-rewind-icon.png',
'click_action' => 'https://aiatsis.gov.au'
);
$fields = array
(
'registration_ids' => $registrationIds,
'data' => $msg
);
$headers = array
(
'Authorization: key=' . API_ACCESS_KEY,
'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/send' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );
$result = curl_exec($ch );
curl_close( $ch );
echo $result;
?>
</code></pre>
<p>My Manifest file:</p>
<pre><code>{
"name": "Webpush",
"gcm_sender_id": "**SENDER_ID**"
}
</code></pre>
<p>The curl terminal command i am using is:</p>
<pre><code>curl --header "Authorization: key=**API_KEY**" --header "Content-Type: application/json" https://fcm.googleapis.com/fcm/send -d "{\"registration_ids\":[\"**SUBSCRIPTION_ID**\"]}"
</code></pre>
<p>I have no idea why this is not working. I have tried:</p>
<ul>
<li>Checking the Key matches the sender id about 150 times.</li>
<li>Deleting my firebase project and starting again with new API key and Sender ID (yes i generated a new endpoint subscription id after i did this).</li>
<li>As mentioned, tried both php and terminal push requests.</li>
</ul>
<p>I have run out of options. And as mentioned several times already the API key matches the corresponding sender ID. I am 100% sure of this. As far as my understanding of the "MismatchSenderId" error, they are trying to tell me that the API key and sender ID do not match. They do match.</p>
<ul>
<li>The sender ID matches the API key</li>
<li>The Subscription ID was generated using the correct sender ID</li>
</ul>
<p>Does anyone have any idea why this is happening?</p>

XAMPP/AJAX/PHP Issue with saving
|
<p>I'm very new to programming and have been trying to make a website application to learn some web development, using XAMPP on Windows as the local web server. I've gotten to the point where I'm trying to incorporate some AJAX by loading some info from the database asynchronously. But any time I make a change to the PHP file that is being called by myFunction() below and save it, the updates don't show up when I refresh the page. I have to close and reopen the browser in order for the changes I've made to appear. The only thing I can think of is that when the browser gets closed the session gets destroyed, but I can't figure out why an update to the PHP file shouldn't show up when I refresh the page. Any help would be appreciated. Here is the file that is shown in the browser: </p>
<pre><code><?php
include 'core/init.php';
include 'includes/overall/header.php';
protect_page();
?>
<body>
<div id="ticker">
<?php
include 'includes/teams.php';
?>
</div>
<div id="teaminfo"></div>
<h2>Welcome to your homepage, <?php echo $user_data['first_name']; ?></h2>
<a href="createleague.php">Create a League</a><br><br>
<a href="logout.php">Logout</a><br><br>
<script>
function myFunction(team_id)
{
if (window.XMLHttpRequest)
{
xmlhttp = new XMLHttpRequest();
}
else
{
xmlhttp = new ActiveXObject('Microsoft.XMLHTTP');
}
xmlhttp.onreadystatechange = function()
{
if(xmlhttp.readyState == 4 && xmlhttp.status == 200)
{
document.getElementById("teaminfo").innerHTML = xmlhttp.responseText;
}
}
xmlhttp.open('GET', 'teaminfo.php?x=' + team_id, true);
xmlhttp.send();
}
</script>
</body>
</html>
</code></pre>
<p>and the php page:</p>
<pre><code><?php
include 'core/database/connect.php';
$team_id = $_GET['x'];
$sql = "SELECT name, wins, losses FROM hockey_team WHERE id = '$team_id'";
$result = mysql_query($sql);
while ($row = mysql_fetch_assoc($result))
{
echo "<h1 id='team_name'>" . $row['name'] . "</h1>";
echo "<p id='wins'>" . $row['wins'] . "</p>";
echo "<p id='losses'>" . $row['losses'] . "</p>";
}
mysql_close();
?>
</code></pre>

Spring Hibernate integration test returns unexpected result
|
<p>I am using Maven, Hibernate and Spring in my application. I have implemented entity classes, DAO classes and service classes in packages of their own. I have problem when testing a service. When unit testing a DAO method that this specific service is calling the result is expected. But when testing a service method that is using this DAO method I don't get the same result. I think this problem is related to integration. Service is annoted with @Transactional. Data source and service are annotated with @Autowired in testing class of service. I attached context configuration of the service testing class.</p>

How to Pass Data From a BroadcastReceiver to an Activity in Android
|
<p>I am working on my first Android app, which is a paging device. It will intercept a SMS message from a certain number with a certain content in it, display that and then allow the user to send a pre-defined reply back to that same number. I have gathered up code snippets from numerous sources (including stackoverflow of course) but I haven't yet got it working.</p>
<p>My file structure is as shown here</p>
<p><a href="https://i.stack.imgur.com/QhnyE.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QhnyE.jpg" alt="enter image description here" /></a></p>
<p>The part I am struggling with is SmsBroadcastReceiver and ReceiveAlert, which should display the content of the SMS and has a button to initiate the reply.</p>
<p>SmsBroadcastReceiver.java looks like this:</p>
<pre><code>package com.example.alert6;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.provider.Telephony;
import android.telephony.SmsMessage;
public class SmsBroadcastReceiver extends BroadcastReceiver {
public static final String EXTRA_MESSAGE = "com.example.alert6.MESSAGE";
@Override
public void onReceive(Context context, Intent intent) {
String smsSender = "";
String smsBody = "";
for (SmsMessage smsMessage : Telephony.Sms.Intents.getMessagesFromIntent(intent)) {
smsSender = smsMessage.getOriginatingAddress();
smsBody = smsMessage.getMessageBody();
}
if (smsSender.equals("+420775367297")) {
if (smsBody.contains("Test")) {
intent.putExtra(EXTRA_MESSAGE, smsBody);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // adding this flag starts the new Activity in a new Task
context.startActivity();
}
}
}
}
</code></pre>
<p>ReceiveAlertActivity.java is this:</p>
<pre><code>package com.example.alert6;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import androidx.core.content.ContextCompat;
import android.Manifest;
import android.content.Intent;

private static final int SMS_PERMISSION_CODE = 101;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_receive_alert);
}
// Get the Intent that started this activity and extract the string
Intent intent = getIntent();
String taskingalert = intent.getStringExtra(SmsBroadcastReceiver.EXTRA_MESSAGE);
// Capture the layout's TextView and set the string as its text
TextView receivedAlert = findViewById(R.id.receivedAlert);
receivedAlert.setText(taskingalert);
public boolean respond(View view) {
if (!hasReadSmsPermission()) {
requestReadAndSendSmsPermission();
return false;
}

}
}
</code></pre>
<p>And the manifest is this:</p>

</application>
</manifest>
</code></pre>
<p>Android Studio is showing errors in SmsBroadcastReceiver and ReceiveAlertActivity but not giving enough information to resolve them.</p>
<p>In SmsBroadcastReceiver, it tells me it cannot resolve method 'startActivity()'. Something needs to go in the brackets, but what?</p>
<p>In ReceiveAlertActivity the problems revolve around receivedalert and taskingalert. It cannot resolve setText because taskingalert is an unknown class. Obviously it's not a class, it's a string so I'm doing something wrong, but what?</p>
<p>Sorting out these problems may not be the end. At the moment I can't test if the app works because the build fails due to the above. Then if I get this lot working, I have some other challenges, like waking up the screen and playing a sound the broadcast receiver is triggered, and stopping the sound when the button is pressed.</p>

ChartJS doughnut colors not showing from a Flask app. All gray
|
<p>Looking for some help here. The doughnut chart is rendering properly, but all the colors are gray. I've scoured the chartjs site and googled, but I can't seem to solve this.</p>
<p>Here's my code:</p>
<pre><code>@app.route('/doughnut_chart')
def doughnut_chart():
values = []
labels =['good', 'mediocre','bad']
colors = ['rgba(0, 153, 0, 0.1)', 'rgba(0,153,153,0.1)','rgba(102,153,51,0.1)']
good_high = db.session.query(func.sum(Jf_Q1.highwellbeing)/func.sum(Jf_Q1.good_job)).\
filter(Jf_Q1.working==1).filter(Jf_Q1.good_job==1)
good_mod = db.session.query(func.sum(Jf_Q1.moderatewellbeing)/func.sum(Jf_Q1.good_job)).\
filter(Jf_Q1.working==1).filter(Jf_Q1.good_job==1)
good_low = db.session.query(func.sum(Jf_Q1.lowwellbeing)/func.sum(Jf_Q1.good_job)).\
filter(Jf_Q1.working==1).filter(Jf_Q1.good_job==1)
values = [0.82483097725875845114*100,0.14935464044253226798*100,0.01966810079901659496*100]
return render_template('results.html', values=values,labels=labels, colors=colors)
</code></pre>
<p>and my script code on the web page:</p>
<pre><code> new Chart(document.getElementById("doughnut-chart"), {
type: 'doughnut',
data: {
labels : {{labels | safe}},
backgroundColor: {{colors | safe}},
datasets:
[{ data : {{values | safe}}
}]
},
options: {
title: {
display: true,
text: 'Doughnut Chart Title'
}
}
});
</code></pre>
<p>Here's how it looks in Chrome's inspector:</p>
<pre><code>
new Chart(document.getElementById("doughnut-chart"), {
type: 'doughnut',
data: {
labels : ['good', 'mediocre', 'bad'],
backgroundColor: ['rgba(0, 153, 0, 0.1)', 'rgba(0,153,153,0.1)', 'rgba(102,153,51,0.1)'],
datasets:
[{ data : [82.48309772587584, 14.935464044253226, 1.9668100799016592]
}]
},
options: {
title: {
display: true,
text: 'Doughnut Chart Title'
}
}
});
</code></pre>
<p>I've tried hex colors such as:</p>
<pre><code>backgroundColor: ["#3e95cd", "#8e5ea2","#3cba9f","#e8c3b9"]
</code></pre>
<p>But still no dice</p>
<p>This is what is looks like in Chrome and in FF:</p>
<p><a href="https://i.stack.imgur.com/QYiIB.png" rel="nofollow noreferrer">my chart</a></p>
<p>Any assistance is greatly appreciated.</p>
<p>Thanks</p>

How to get Row where two Columns equal specific values
|
<p>I'm very new and I'm trying to create a Time in/Time out sheet. I have 2 separate sheets, first(ACTIVE) is where the trigger happens that starts the onEdit(e) script. All the functions that start onEdit(e) affects the second sheet(PASSIVE) to fill out Columns A(Last Name), B(First Name), C(Location), D(Time Out). I finished making the Time out functions by getting value of A, B, C + Active Row(this isn't the code). The trigger is always on the same row as the values being copied, so it was relatively simple. On the PASSIVE sheet I have all the values being stored using a code someone made called addRecord where it gets last row + 1 of the PASSIVE sheet and installs the values grabbed from the ACTIVE sheet and plugs them in. So it adds records without overwriting anything. Works beautifully. However making a "time in" function has been difficult. E(Time In) My idea is to getRow of the PASSIVE sheet by searching PASSIVE!A for the Value grabbed from (ACTIVE!A + Active Row) once it finds a match, it sees if (PASSIVE!E + the matched row) is empty. If it is, it adds new.Date and finishes. If it isn't empty, it ignores this row and continues searching down the line for the next Row that has PASSIVE!A match the grabbed value. Once it finds this Row, getRow. setValue of (PASSIVE!E + grabbed row, new Date()) </p>
<p>I did find a function online to find the first row that matched the ACTIVE!A with PASSIVE!A. But it kept overwriting the date on the first match. It never ignored row with nonempty cell to the next match row. Maybe I was just slightly off, which is why I'm asking for a lot of detail and explanation in the Answers.
This was the Code I used from another answer. </p>
<pre><code>function getCurrentRow() {
var currentRow = SpreadsheetApp.getActiveSheet().getActiveSelection().getRowIndex();
return currentRow;
}
function onSearch1()
{
</code></pre>
<p>What I added</p>
<pre><code> var row = getCurrentRow();
var activeLocation = getValue('ACTIVE!A' + row);
</code></pre>
<p>Continued Other Code</p>
<pre><code> var searchString = activeLocation;
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("PASSIVE");
var column =1; //column Index
var columnValues = sheet.getRange(2, column, sheet.getLastRow()).getValues(); //1st is header row
var searchResult = columnValues.findIndex(searchString); //Row Index - 2
</code></pre>
<p>What I added</p>
<pre><code> setValue(PASSIVE!E + searchResult, new Date().toLocaleString())
</code></pre>
<p>It worked if everyone has a different name, but the search Result always found the first row of the match, I tried adding an if ACTIVE!A == PASSIVE!A
&& PASSIVE!E =="", grabRow (I know this isn't proper code) But I didn't even know where to put this if function or if it would work or if it would just keep coming up false after it runs the first time true. </p>
<p>Continued Other Code</p>
<pre><code>if(searchResult != -1)
{
//searchResult + 2 is row index.
SpreadsheetApp.getActiveSpreadsheet().getSheetByName("PASSIVE").setActiveRange(sheet.getRange(searchResult + 2, 1))
}
if(searchResult = searchResult2) {
setValue('PASSIVE!E' + searchResult, new Date().toLocaleString())
}
}
Array.prototype.findIndex = function(search){
if(search == "") return false;
for (var i=0; i<this.length; i++)
if(this[i] == search) return i;
return -1;
}
</code></pre>
<p>So this is what I used, but not sure if it's the right way to go about this. Every time I used it, it would only set the SearchResult to the first row it found that had the searchString I'd actually prefer if it found the last row, considering the add record goes down over time and signing in should be the most recent name. But I'm guessing if I can just get a function that searches a range and finds the row for two values in specific columns, I can then just <code>setValue('PASSIVE!E' + foundRow, new Date().toLocaleString())</code></p>
<p>Edit 5/9/2019 17:34 PST
Thank you to those Answering. I'm expanding on the question.</p>
<pre><code>function rowWhereTwoColumnsEqual(value1,col1,value2,col2) {
var value1=value1 || 'A1';//testing
var value2=value2 || "";
</code></pre>
<p>The idea I'm having is to search Column1 of another sheet for, let's say, 'SheetA1' (the first sheet). And Column3 of another sheet for "" (cellisempty).</p>
<pre><code>var value1= 'Sheet1!A1';
var value2= "";
var col1='Sheet2!A';
var col2='Sheet2!C';
var ss=SpreadsheetApp.getActive();
var sh=ss.getSheetByName('Sheet2');
var rg=sh.getDataRange();
var vA=rg.getValues();
</code></pre>
<p>However, I don't know how the vA works. I also want to getRow() of the Row that is found in order to use that number in another function.</p>

Sql transaction is complete exception
|
<p>I have a strange problem. All documentation states that the <code>SaveChanges()</code> method must be first called before committing the transaction but in my case it is throwing an exception if done this way.
By calling Commit before <code>SaveChanges()</code> I can avoid the "Sql transaction is complete exception"</p>

AppFieldValidator.Validate(sc);
db.Entry(sc).State = System.Data.EntityState.Added;

db.SaveChanges();
foreach (var obj in shops)

<p><code>Undefined function or variable 'HxR'</code> </p>
<p>however, I have already defined it as <code>Hx=HxR+HxL</code> in my code. Matlab give the reason for this problem as(The size of the indicated variable or array appears to be changing with each loop iteration). Could anyone have any idea to help, I appreciate it </p>

How to display the correct data in their respective text inputs?
|
<p>I am having trouble displaying the SessionName, SessionDate and SessionTime in their respective text inputs. What should happen is that the user is suppose to select a Session (Assessment) from the drop down menu. Now when they submit the drop down menu, the details of the Session which are SessionName, SessionDate and SessionTime, should be displayed in their text inputs. But instead I am recieving undefined variable errors which are these below:</p>
<blockquote>
<p>Notice: Undefined variable: dbSessionName in ...on line 243</p>
<p>Notice: Undefined variable: dbSessionDate in ... on line 244</p>
<p>Notice: Undefined variable: dbSessionTime in ... on line 245</p>
</blockquote>
<p>How can I get the SessionName, SessionTime and SessionDate to be displayed in their respective text inputs?</p>
<p>Below is the code:</p>
<pre><code>$sessionquery = "
SELECT SessionId, SessionName, SessionDate, SessionTime, ModuleId
FROM Session
WHERE
(ModuleId = ?)
ORDER BY SessionDate, SessionTime
";
$sessionqrystmt=$mysqli->prepare($sessionquery);
// You only need to call bind_param once
$sessionqrystmt->bind_param("s",$_POST['modules']);
// get result and assign variables (prefix with db)
$sessionqrystmt->execute();
$sessionqrystmt->bind_result($dbSessionId,$dbSessionName,$dbSessionDate,$dbSessionTime, $dbModuleId);
$sessionqrystmt->store_result();
$sessionnum = $sessionqrystmt->num_rows();
if($sessionnum ==0){
echo "<p>Sorry, You have No Assessments under this Module</p>";
} else {
$sessionHTML = '<select name="session" id="sessionsDrop">'.PHP_EOL;
$sessionHTML .= '<option value="">Please Select</option>'.PHP_EOL;
while ( $sessionqrystmt->fetch() ) {
$sessionHTML .= sprintf("<option value='%s'>%s - %s - %s</option>", $dbSessionId, $dbSessionName, $dbSessionDate, $dbSessionTime) . PHP_EOL;
}
$sessionHTML .= '</select>';
$assessmentform = "<form action='".htmlentities($_SERVER['PHP_SELF'])."' method='post' onsubmit='return sessionvalidation();'>
<p>Assessments: {$sessionHTML} </p>
<p><input id='sessionSubmit' type='submit' value='Submit Assessment' name='sessionSubmit' /></p>
<div id='sessionAlert'></div>
</form>";
echo $assessmentform;
}
}
if (isset($_POST['sessionSubmit'])) {
$currentsession = "form action='".htmlentities($_SERVER['PHP_SELF'])."' method='post'>
<p>Current Assessment's Date/Start Time:</p>
<p>Assessment: <input type='text' id='currentAssessment' name='Assessmentcurrent' readonly='readonly' value='{$dbSessionName}'/> </p> //Line 243
<p>Date: <input type='text' id='currentDate' name='Datecurrent' readonly='readonly' value='{$dbSessionDate}'/> </p> //Line 244
<p>Start Time: <input type='text' id='currentTime' name='Timecurrent' readonly='readonly' value='{$dbSessionTime}'/> </p> //Line 245
</form>
";
echo $currentsession;
}
</code></pre>
<p><strong>UPDATE:</strong></p>
<p>Could the code below do it:</p>
<pre><code>if (isset($_POST['sessionSubmit'])) {
$sessionquery = "
SELECT SessionId, SessionName, SessionDate, SessionTime, ModuleId
FROM Session
WHERE
(ModuleId = ?)
ORDER BY SessionDate, SessionTime
";
$sessionqrystmt=$mysqli->prepare($sessionquery);
// You only need to call bind_param once
$sessionqrystmt->bind_param("s",$_POST['modules']);
// get result and assign variables (prefix with db)
$sessionqrystmt->execute();
$sessionqrystmt->bind_result($dbSessionId,$dbSessionName,$dbSessionDate,$dbSessionTime, $dbModuleId);
$sessionqrystmt->store_result();
$currentsession = "<form action='".htmlentities($_SERVER['PHP_SELF'])."' method='post'>
<p>Current Assessment's Date/Start Time:</p>

<p>Do I need the store_result(); in this situation?</p>

Django and React: csrf cookie is not being set in request header
|
<p>To explain my situation, if I logged in from backend, csrf cookie is set in cookie tab, the problem occur in frontend, if i try to login from there, csrf cookie is not in request header (being undefined), some code provided:</p>
<p>settings.py:</p>
<pre><code>ALLOWED_HOSTS = ['*']
ACCESS_CONTROL_ALLOW_ORIGIN = '*'
CORS_ORIGIN_ALLOW_ALL = True
CORS_ALLOW_CREDENTIALS = True
ACCESS_CONTROL_ALLOW_CREDENTIALS = True
ACCESS_CONTROL_ALLOW_METHODS = '*'
ACCESS_CONTROL_ALLOW_HEADERS = '*'
'''
SESSION_COOKIE_SECURE = True
'''
CSRF_COOKIE_SAMESITE = 'None'
SESSION_COOKIE_SAMESITE = 'None'
CSRF_TRUSTED_ORIGINS = [ "http://127.0.0.1:3000",'http://127.0.0.1:8000','http://localhost:3000']
</code></pre>
<p>setting SAMESITE protocol to anything else haven't made any change</p>
<p>in views.py, we have login view (class based):</p>
<pre><code>class LoginView(views.APIView):
permission_classes = [AllowAny,]
serializer_class = serializer.LoginSerializer
def post(self,request):
data = serializer.LoginSerializer(data=request.data)
print(data.is_valid())
if data.is_valid():
email = data.data['email']
password = data.data['password']
auth = authenticate(username=email,password=password)
if auth:
login(request,auth)
return HttpResponse("Success",status=200)
else:
print(password == "")
if email == "" and password =="":
return HttpResponse('Both email and password field are empty',status=400)
elif email == "":
return HttpResponse('Email field is empty',status=400)
elif password == "":
return HttpResponse('Passowrd field is empty',status = 400)
else:
return HttpResponse("Both email and password fields are empty",status=400)
</code></pre>
<p>in serializer.py, we got the login serializer:</p>
<pre><code>class LoginSerializer(serializers.Serializer):
email = serializers.CharField(required=False)
password = serializers.CharField(required=False,allow_null=True,allow_blank=True)
</code></pre>
<p>in react (frontend side), here is how i am making a post request:</p>
<pre><code>function Login(){
const [login,setLogin] = useState({'email':'','password':''})
const {email,password} = login
const navigate = useNavigate()
let handleChange = (e)=>{
setLogin(
{
...login,
[e.target.name]:e.target.value
}
)
}
let handleSubmit = (e)=>{
e.preventDefault()
axios.post('http://127.0.0.1:8000/login/',login,{headers: {'Content-Type': 'application/json','X-CSRFToken':Cookies.get('csrftoken')}}).then(
(res)=>{
console.log(res)
console.log(Cookies.get('csrftoken')) //undefined here
}
).catch((e)=>{
console.log(e)
}
})
}
}
</code></pre>
<p>this is part of the code btw ^.</p>
<p>edit:
I have a csrf view too, not sure how to use it:</p>
<pre><code>class GetCSRFToken(views.APIView):
permission_classes = [AllowAny, ]
def get(self, request, format=None):
return Response({ 'success': 'CSRF cookie set' })
</code></pre>
<p>any help is welcomed.</p>

Strange chars after decoding with java.util.Base64.getDecoder()
|
<p>Im trying to encrypt some user data in the DB then decrepit it back when showing it to users</p>
<p>Im doing this using JPA, Eclipse link 2.7.1, and MYSql 5.6 </p>
<p>the User entity looks like that:</p>

<p>My problem is sometimes when I read the decoded <code>aboutMe</code> field from the <code>user</code> entity it looks like having strange chars like this
"��t����a:i3��5�o" and sometimes it'll look just fine without any strange chars. </p>
<p>Do I do anything wrong with the decoding steps?</p>
<p>I really appreciate your help. </p>

How do I get the log-in section to disappear when users are logged in?

<p>I want the "log in block" to be hidden to my users once they are logged in. It is very confusing to still see the log in section.

<p>So my question is, do I need to insert HTML code, CSS code and/or JAVASCRIPT code to make this work? And what is the code that I need to insert and where? I have tried researching and playing around, but to no avail. Any advice would be MUCH appreciated. Thank you!</p>

PHP- getting the value of a cell for use with an api
|
<p>Sorry if this is a stupid question, I'm pretty new at PHP. </p>
<p>So first, here is what I'm trying to do:</p>
<p>I am pulling information from MYSQL and displaying the info on a page. specifically this bit:</p>
<pre><code>while($rowsID = mysql_fetch_assoc($sIDD))
{
echo '<tr>';
foreach($rowsID as $key => $cell){
print '<td>'.$cell.'</td>';
}
</code></pre>
<p>This works fine and displays the info I want.</p>
<p>The information from that cell, I want to plug into:</p>
<pre><code>$sid = $rowsID['steamID'];
$key = '<yoink>';
$slink =file_get_contents('http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=' . $key . '&steamids=' . $sid . '&format=json');
$myarray = json_decode($slink, true);
print '<img src=';
print $myarray['response']['players'][0]['avatarmedium'];
print '>'; `
</code></pre>
<p>This does not work. It won't pull the actual number from the cell and put it into $sid. I've at a loss here. I'm googled for days, and most of my code is frankenstiened from bits I've found around here, so I'm not even sure I'm on the right track. I hope I've clearly explained my problem and provided enough info. Thanks for any help.</p>
<p>The full code: </p>

<p>I realize the code is probably a disaster, I plan on cleaning it up once I have it working and understand more fully what I'm looking at. I've copie and patched together code from a lot of different sources, as well as attempted my own. Don't hate me. :-)</p>

highcharts stacked area
|
<p>So I think I may have encountered a Highcharts bug in terms of stacked area:</p>
<p><a href="http://jsfiddle.net/dRL6t/2/" rel="nofollow">JSFiddle Highcharts Example</a></p>
<p>In this example, the "Social" has a start point before the "Online Video" and seems to render the points of the stacked areas erratically. If you were to deselect the charts from left to right, and then select them from right to left, the charts will render correctly. Has anyone else encountered this?</p>

Is it possible to add boolean conditions into a Binary Search Tree?
|
<p>I am trying to implement a Decision tree which from my understanding , a Decision Tree is a Binary Tree with boolean conditions , feel free to correct me if i am wrong. I am trying to implement an Add() function with a parameter of a template where i want to add a boolean conditions. I am using this link : <a href="http://csharpexamples.com/c-binary-search-tree-implementation/" rel="nofollow noreferrer">http://csharpexamples.com/c-binary-search-tree-implementation/</a> for help.I was trying to compare a boolean value with an int value knowing it won't work so i switched to using a template . This is my first time trying to implement a Binary Search Tree.</p>
<p>Here is the code for my node class:</p>
<pre><code> using System.Collections;
using System.Collections.Generic;
public class BST_NodeClass<E>
{
public BST_NodeClass<E> LeftNode { get; set; }
public BST_NodeClass<E> RightNode { get; set; }
public BST_NodeClass<E> Data { get; set; }
};
</code></pre>
<p>Here is the code for my Binary Search Tree :</p>
<pre><code>using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class BST<E> where E : System.IComparable<E>
{

public bool Add (E condition)
{
BST_NodeClass<E> before = null, after = this.Root;
while (after!= null)
{
before = after;
if(condition < after.Data)//Is new node in the left tree?
{
after = after.LeftNode;
}
else if (condition > after.Data)//Is the new node in the right tree?
{
after = after.RightNode;
}
else
{
//Exist same value
return false;
}
BST_NodeClass<E> newNode = new BST_NodeClass<E>();
newNode.Data = condition;
if (this.Root == null)//Tree is empty
this.Root = newNode;

How to search for Specific item in User's Quick.db Inventory
|
<p>Pretty much, I'm having difficulty being able to find a role in a user's Quick.db inventory. I'd like to do this to: allow them to only buy a role once; allow them to equip an owned role only <em>if</em> it's found in their inventory. Problem is that the user is able to buy a role more than once, and able to equip a role even if it's not owned. I believe the line I'm having trouble with is <code>if(db.has(message.author.id + '.items' + 'hot rod red'))</code> (possibly because I'm searching for a role and not a plain text item?), but it could be something else.</p>
<p>I'm completely lost and run out of ideas at this point, any help is appreciated!</p>
<p><strong>Code for Equipping a Role:</strong></p>
<pre><code> let user = message.guild.members.cache.get(message.author.id)
let items = await db.fetch(message.author.id);
if(items === null) items = "Nothing"
let author = db.get(`items_${message.guild.id}_${user.id}`)
if (args[0] == 'red') {
let rejectEmbed = new Discord.MessageEmbed()
.setDescription('You do not own this role!');
if(db.has(message.author.id + '.items' + 'hot rod red')){
if (message.member.roles.cache.some(role => role.name === 'hot rod red')) {
let embed = new Discord.MessageEmbed().setDescription('You already have this role!');
return message.channel.send(embed); }
else {
await message.guild.members.cache.get(user.id).roles.add('733373020491481219');
let embed = new Discord.MessageEmbed().setDescription(`You now have the ${message.guild.roles.cache.get('733373020491481219')} role!`);
message.channel.send(embed);
user.roles.remove(user.roles.highest);
}

I have two i2c devices. Both alone work well, but when I read from one, and then write to the other, the second one is not an ancknowledging

<p>I have two devices MPU6050 and EEPROM 24C256. I can write and read from both alone. But when I try to read from MPU6050 and than write data to EEPROM in the same session, the EEPROM does not respond. I am using mbed OS libraries. And my question is.. Is it library, code or hardware problem?</p>

How to avoid object references for spawned objects in Unity 2D?
|
<p>At the moment I am programming a Unity 2D game. When the game is running the cars start moving and respawn continuously. I added kind of a life system to enable the possibility to shoot the cars. My issue is that my health bar as well as my score board need references to the objects they refer to, but I am unable to create a reference to an object which is not existing before the game starts. Another issue is that I don't know how to add a canvas to a prefab in order to spawn it with the cars continuously and connect them to the car. Is there a way to avoid these conflicts or how is it possible to set the references into prefabs. I will add the code of the spawner, the car and the the scoreboard. Already thank you in advance</p>

<p>But it doesn't call <code>onLoadFinished</code> method. I checked <code>Log</code> output... <code>LoaderManager</code> calls <code>onCreateLoader</code> but it never calls <code>onLoadFinished</code> except first run (when app started and <code>ViewPager</code> shows a first page (<code>Fragment</code>)). It's all! After if I switch a page to a next and a next and return to a first page <code>LoaderManager</code> doesn't call <code>onLoadFinished</code> for the first page too. But it creates loader calling <code>onCreateLoader</code> and resets loader calling <code>onLoaderReset</code>. Is it a joke from Google?</p>

<p>In this code it echo htmlcontent of webpage then with regexp it should return <code>href</code> of anchor tag between div which class name is <code>product-list-options</code> and <code>product-list-item</code></p>
<p>Current output is - </p>
<pre><code>http://www.universalapplianceparts.com/termsofservice.aspx
</code></pre>
<h2>Here Regexp reading my html content from cURL in reverse order and returning first href value in anchor tag.</h2>
<p>Expected output in array value - <code>/W10130694LatchAssyWhiteHandle.aspx</code></p>
<p>Any help would be appreciated.</p>

Setting up https on Google Compute Engine running WordPress
|
<p>I have set up WordPress on GCE using the marketplace:</p>
<p><a href="https://cloud.google.com/wordpress/" rel="nofollow noreferrer">https://cloud.google.com/wordpress/</a></p>
<p>I have set up the domain name to worldbreakersgame.com and reserved a static IP. I then followed the instructions here to set up https:</p>
<p><a href="https://onepagezen.com/free-ssl-certificate-wordpress-google-cloud-click-to-deploy/" rel="nofollow noreferrer">https://onepagezen.com/free-ssl-certificate-wordpress-google-cloud-click-to-deploy/</a></p>
<p>One part of the tutorial that did not work, <code>/etc/apache2/sites-available/wordpress.conf</code> did not exist. I edited <code>/etc/apache2/sites-available/wordpress-http.conf</code> instead.</p>
<p>However, when going to <a href="https://www.worldbreakersgame.com" rel="nofollow noreferrer">https://www.worldbreakersgame.com</a>, I still get the error message that "Your connection is not private". I think that there is an issue with the certificate I issued through Let's Encrypt/certbot, but I am not sure.</p>
<p>I tried restarting the apache server again but it does not seem to help.</p>
<p>Here are the relevant WordPress settings:</p>

#SSLVerifyDepth 10
# SSL Engine Options:
# Set various options for the SSL engine.
# o FakeBasicAuth:
# Translate the client X.509 into a Basic Authorisation. This means that
# the standard Auth/DBMAuth methods can be used for access control. The
# user name is the `one line' version of the client's X.509 certificate.
# Note that no password is obtained from the user. Every entry in the user
# file needs this password: `xxj31ZMTZzkVA'.
# o ExportCertData:
# This exports two additional environment variables: SSL_CLIENT_CERT and
# SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
# server (always existing) and the client (only existing when client
# authentication is used). This can be used to import the certificates
# into CGI scripts.
# o StdEnvVars:
# This exports the standard SSL/TLS related `SSL_*' environment variables.
# Per default this exportation is switched off for performance reasons,
# because the extraction step is an expensive operation and is usually
# useless for serving static content. So one usually enables the
# exportation for CGI and SSI requests only.
# o OptRenegotiate:
# This enables optimized SSL connection renegotiation handling when SSL
# directives are used in per-directory context.

# SSL Protocol Adjustments:
# The safe and default but still SSL/TLS standard compliant shutdown
# approach is that mod_ssl sends the close notify alert but doesn't wait for
# the close notify alert from client. When you need a different shutdown
# approach you can use one of the following variables:
# o ssl-unclean-shutdown:
# This forces an unclean shutdown when the connection is closed, i.e. no
# SSL close notify alert is send or allowed to received. This violates
# the SSL/TLS standard but is needed for some brain-dead browsers. Use
# this when you receive I/O errors because of the standard approach where
# mod_ssl sends the close notify alert.
# o ssl-accurate-shutdown:
# This forces an accurate shutdown when the connection is closed, i.e. a
# SSL close notify alert is send and mod_ssl waits for the close notify
# alert of the client. This is 100% SSL/TLS standard compliant, but in
# practice often causes hanging connections with brain-dead browsers. Use
# this only for browsers where you know that their SSL implementation
# works correctly.
# Notice: Most problems of broken clients are also related to the HTTP
# keep-alive facility, so you usually additionally want to disable
# keep-alive for those clients, too. Use variable "nokeepalive" for this.
# Similarly, one has to force some clients to use HTTP/1.0 to workaround
# their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
# "force-response-1.0" for this.
# BrowserMatch "MSIE [2-6]" \
# nokeepalive ssl-unclean-shutdown \

MS Access: filling in missing values and adding numbers
|
<p>I wasn't sure what a proper title would be, I hope this works.</p>
<p>I'm having trouble converting rows to columns with a certain table, and found possible solutions online. However, I feel like I need to edit this table to enable me to actually convert the rows into columns.</p>
<p>The table looks a little bit like this:</p>
<pre><code>ID1 patientID patientname study_date echo_var
1 1234 Bob 01-01-2014 15
2 1234 01-01-2000 13
3 1234 Bob 08-08-2012 14
4 1234 Bob 13-02-2005 13
5 6625 Louie 12-11-2010 25
6 6625 08-10-1998 20
7 6625 Louie 19-04-2006 21
</code></pre>
<p>This is information automatically harvested from an electronic patient system and normally contains a lot more variables per row, but I'm only interested in one (echo-var) right now. All the rows represent specific patient visits. Because of changes in the electronic system the tool I use can't properly extract all data from older records, which is why some of the names aren't filled in properly. Seeing as their patientID is unique for every patient I can fill the names in manually, but there's about 6000 records so I was hoping there would be a more elegant manner of doing so.</p>
<p>This is not much of a bother though, the major thing is converting the rows into columns (see below). So I found a solution online for my problem, but I feel like I am hindered because the separate datapoints per patient aren't numbered uniquely for every patient, as below. I want every seperate datapoint to be numbered for each patient, so the first visit, chronologically, is numbered 1 for each patient individually, and the second is 2, etc.</p>
<pre><code> ID1 patientID patientname study_date echo_var echo_number
1 1234 Bob 01-01-2014 15 4
2 1234 Bob 01-01-2000 13 1
3 1234 Bob 08-08-2012 14 3
4 1234 Bob 13-02-2005 13 2
5 6625 Louie 12-11-2010 25 3
6 6625 Louie 08-10-1998 20 1
7 6625 Louie 19-04-2006 21 2
</code></pre>
<p>If I have this I think I know how to convert the rows to columns, which is what I ultimately want, like below.</p>
<pre><code>patientID echo_number1 study_date1 echo_var1 echo_number2 study_date2 echo_var2
1234 1 01-01-2000 13 2 13-02-2005 13
6625 1 08-10-1998 20 2 19-04-2006 21
</code></pre>
<p>There would be rows for date no. 3 and its respective measurement and so forth.
I guess the echo_number(x) variables aren't crucial, but the dates and respective measurement would be.</p>
<p>Does anyone know the proper way to go for this? As I've mentioned, I've tried searching for these particular problems but I'm having trouble finding a solution. If anything's unclear please let me know. If anyone knows how how to go from the first table to the last (without the steps in between), that would work as well.</p>
<p>Many thanks in advance</p>
<hr>
<p>Using a table similar to the second one above, I've tried the following queries:</p>
<pre><code>SELECT
[patientID],
"echo_number" & [echo_number] & "_" & "echo_var" AS [ValueID],
[echo_var] AS [ValueValue]
FROM [TABLENAME]
UNION ALL SELECT
[patientID],
"echo_number" & [echo_number] & "_" & "study_date" AS [ValueID],
[study_date] AS [ValueValue]
FROM [TABLENAME];
</code></pre>
<p>Followed by:</p>
<pre><code>TRANSFORM Sum(NEWQUERY.ValueValue) AS SumOfValueValue
SELECT NEWQUERY.patientID
FROM NEWQUERY
GROUP BY NEWQUERY.patientID
PIVOT NEWQUERY.ValueID
</code></pre>
