What's wrong with named pipes used between 2 processes (no. 2)?
|
<p>So, let's start from beginning: 2 processes 1 pipe to communicate, right? No! because communication is blocking, one waits for another. We need results from the second process through a different channel. Though it seems redundant it is not.</p>
<p>Let's change it a bit: 2 processes 2 pipes, you can call one process the server and the other the client. One pipe sends jobs to clients and the other is used to collect results from the clients to the server.</p>
<p>For convenience we call each pipe with the process name that is used for reading so, london reads london pipe and so on. That's the diagram of pipes and processes:</p>
<pre><code>london ----writes madrid pipe-------->
london <----reads london pipe------ |
^ |
| |
madrid ----writes london pipe-----> v
madrid <----reads madrid pipe---------
</code></pre>
<p>Let's use 'london' as server and 'madrid' as client: server is responsible to end the endless loop.</p>
<p>And this is the solution:</p>
<pre><code>#!/bin/bash
shopt -u failglob
shopt -s extglob nullglob dotglob
DIR=$( cd "$( dirname "$0" )" && pwd )
function london (){
local i message answer london madrid
london=london_$RANDOM.$RANDOM.$RANDOM.$$
madrid=madrid_$RANDOM.$RANDOM.$RANDOM.$$
cd $DIR
mkfifo $london
mkfifo $madrid
( madrid $madrid $london ) &
echo "parent id: $$, child id: $!"
i=0
#a mesterious situation: sometimes '3< $london' just breaks it (?!)
exec 3<> $london
exec 4> $madrid
while true; do
message="Greetings from London!($i)"
echo "$message" >&4
read -r answer <&3
echo 'London says:> '"$answer" #>& /dev/stdout
(( i++ ))
if [[ i -gt 1 ]]; then
echo 'quit' >&4
break
fi
done
wait
cd "$DIR"
rm -rf $london
rm -rf $madrid
}
function madrid (){
local i message answer madrid london
madrid=$1
london=$2
cd $DIR
i=0
exec 3> $london
exec 4< $madrid
while true; do
read -r answer <&4
echo 'Madrid says:> '"$answer" #>& /dev/stdout
message="Greetings from Madrid!($i)"
echo "$message" >&3
(( i++ ))
if [[ $answer = 'quit' ]]; then
break
fi
done
}
london
</code></pre>
<p>At function 'london' there is a comment just before</p>
<pre><code> exec 3<> $london
</code></pre>
<p>if you change this to</p>
<pre><code> exec 3< $london
</code></pre>
<p>as it should(!) be then, I faced a situation where my program stalled repeatedly!
After a few changes from <> to < and vice versa the problem eliminated and I can't reproduce it! I'm using an Ubuntu system so if anybody can test the program with his/her system and post some comments it will welcomed.</p>

How to submit django model forms via ajax, preventing reload/refresh on submit
|
<p>Problem: every time I click the login button, the page reloads and then goes to some funny URL appending 'undefined' in the URL - <a href="http://127.0.0.1:8000/accounts/userLogin/undefined" rel="nofollow noreferrer">http://127.0.0.1:8000/accounts/userLogin/undefined</a>. I would like if the form has errors, then the form errors are shown with the form again for the user to correct and if there are no errors, then log in the user.</p>
<p>PS: I am relatively new to this Django/javascript world. </p>
<p>Here is my code:</p>
<ol>
<li>View</li>
</ol>
<pre><code>@method_decorator(csrf_protect, name='post')
class UserLogin(LoginView):
"""docstring for UserLogin"""
template_name = 'accounts/login.html'
def get(self, request):
'''a func to work on the request.POST'''
print("getting the form for you ")
form = LoginForm()
return render(request,self.template_name,{'form':form})
def post(self, request):
form = LoginForm(request.POST)
print("go the data for you")
if request.is_ajax():
print("entered form")
if form.is_valid():
print("form valid")
email = form.cleaned_data['email']
try:
user = User.objects.get(email=email)
print("user obj", user)
if user.check_password(form.cleaned_data['password']):
# 0-super admin, 1-dept admin,2-dept staff, 3-end user
print("correct password")
if user.account_type == 4:

to = 'dept_staff'
elif user.account_type == 1:
to = 'super_user'
else:
to = None
res = {'status':'ok', 'error':False, 'acc_type':to, 'data':user.email}
else:

SwingNode contents not resizing when the SwingNode's parent resizes
|
<p>EDIT:
I've left my original question as it was, below. If you wish to test the issue using the AnchorFX sourcecode and my code below, you should be able to recreate the problem. It happens in some other circumstances as well, and is similar to the issues in these two questions: <a href="https://stackoverflow.com/questions/30594004/resize-swingnode-in-pane">Resize SwingNode in Pane</a> and <a href="https://stackoverflow.com/questions/20350890/how-to-resize-swing-control-which-is-inside-swingnode-in-javafx8">How to resize Swing control which is inside SwingNode in JavaFX8?</a> Neither of whose answers proved helpful to me, but maybe the answer I found will help someone else in the future. </p>

<p>I have a <code>JTable</code> inside a <code>JScrollPane</code> and I need to embed it into a javafx application. I am trying to do this using the <a href="https://github.com/alexbodogit/AnchorFX" rel="noreferrer">AnchorFX docking framework</a>. I also need this SwingNode to somehow be inside a <code>Control</code> (the two I have tried are <code>ScrollPane</code> and <code>SplitPane</code>) so that I can add a <code>ContextMenu</code> to it which is consistent with the rest of the application. </p>
<p>The problem is, when I 'dock' and 'undock' tabs or simply resize the window or the panes inside the window, the <code>JScrollPane</code> with the table in it does not resize properly.</p>
<p>I have modified one of the demos from the AnchorFX project to show my problem:</p>
<pre><code>public class AnchorFX_substations extends Application {
@Override
public void start(Stage primaryStage) {
DockStation station = AnchorageSystem.createStation();
Scene scene = new Scene(station, 1024, 768);
DockNode node1 = AnchorageSystem.createDock("Node", generateJTableNode());
node1.dock(station, DockNode.DockPosition.CENTER);
DockNode subNode = AnchorageSystem.createDock("subNode 1", generateJTableNode());
subNode.dock(station, DockNode.DockPosition.LEFT);
subNode.floatableProperty().set(false);
DockNode subNode2 = AnchorageSystem.createDock("subNode 2", generateJTableNode());
subNode2.dock(station, DockNode.DockPosition.LEFT);
AnchorageSystem.installDefaultStyle();
primaryStage.setTitle("AnchorFX SubStation");
primaryStage.setScene(scene);
primaryStage.show();
}
private Control generateJTableNode() {
ScrollPane contextMenuPane = new ScrollPane();
SwingNode swingNode = new SwingNode();
DefaultTableModel model = new DefaultTableModel();
JTable table = new JTable(model);
// Create a couple of columns
model.addColumn("Col1");
model.addColumn("Col2");
// Append a row
for(int i = 0; i < 200; i++) {
model.addRow(new Object[]{"col 1 row " + i, "col 2 row "+i});
}
JScrollPane scrollPane = new JScrollPane(table);
swingNode.setContent(scrollPane);
contextMenuPane.setFitToHeight(true);
contextMenuPane.setFitToWidth(true);
contextMenuPane.setContent(swingNode);
return contextMenuPane;
}

Access objects in array list

<p>I am trying to access objects an arraylist using javascript, the arraylist is:</p>
<pre><code>membersList:{

<p>I am trying to access the <code>primary email</code> from this list for which I wrote a code i.e</p>
<pre><code>for (var j in membersList) {
var member = membersList[j];
Logger.log('member Email:' + member);
}
</code></pre>
<p>which just returns me </p>
<pre><code>[18-06-12 15:39:55:982 EDT] member Email:admin#directory#users
[18-06-12 15:39:55:982 EDT] member Email:{"orgUnitPath":"/","isMailboxSetup":true,"id":"1076823423424234","isAdmin":false,"suspended":false,"isDelegatedAdmin":false,"isEnforcedIn2Sv":false,"etag":"\"npJcgsdfsadfsfsff\"","ipWhitelisted":false,"changePasswordAtNextLogin":false,"customerId":"C01looera","includeInGlobalAddressList":true,"lastLoginTime":"1970-01-01T00:00:00.000Z","primaryEmail":"ilda.donofrio@domain.org","isEnrolledIn2Sv":false,"kind":"admin#directory#user","name":{"givenName":"ilda","familyName":"donofrio","fullName":"ilda donofrio"},"creationTime":"2018-06-10T11:56:45.000Z","emails":[{"address":"ilda.donofrio@domain.org","primary":true}],"agreedToTerms":true}
[18-06-12 15:39:55:983 EDT] member Email:"npJcgsdfsadfsfsff/npJcgsdfsadfsfsff\"
</code></pre>
<p>When I tried with:</p>
<pre><code>Logger.log('member Email:' + member.primaryEmail);
</code></pre>
<p>Its throwing:</p>
<pre><code>[18-06-12 16:02:53:630 EDT] member Email:undefined
[18-06-12 16:02:53:630 EDT] member Email:undefined
[18-06-12 16:02:53:631 EDT] member Email:undefined
</code></pre>
<p>Is there a way to extract the value of just the <code>primaryEmail</code> using the script? I am a newbie to javascript and google scripts so please pardon me if its a stupid question.</p>

SQL error 1064. Statement works in mysqladmin but not in PHP script
|
<p>I have a PHP script installed on the admin side of our website that is supposed to allow us to run SQL queries. However, I'm not getting the same results as I am when running it through mysqladmin on our host company's OPS page.</p>
<p><strong>When I submit:</strong></p>
<pre><code>SELECT orders_id FROM `orders_status_history` WHERE `comments` LIKE '%12345%'
</code></pre>
<p>I get one result (my test record) in mysqladmin. So it's successful.</p>
<p><strong>However, when I submit it through the PHP program, I get:</strong></p>
<pre><code>MySQL error 1064: You have an error in your SQL syntax;
check the manual that corresponds to your MySQL server version for the right syntax to use near '\'%12345%\'' at line 1
While executing:
SELECT orders_id FROM `orders_status_history` WHERE `comments` LIKE \'%12345%\'
</code></pre>
<p>I'm assuming the syntax is different when submitting through PHP but I can't, for the life of me, figure out what it's supposed to be. I've tried prefacing the single quotes with a slash. I've tried double quotes. I've spent a couple hours surfing the web. I've tried so many things I can't even keep them straight anymore. I'm assuming it is something simple. Can anyone point me in the right direction?</p>
<p>Here is the code from the php program. The user pastes the SQL query in a text area and hits a SEND button. Again, the <em>exact</em> same query works in mysqladmin but not when using this PHP program:</p>
<pre><code><?php
/*
$Id: sql_interface.php,v 1.00 2004/08/13 00:28:44 draven Exp $

require('includes/application_top.php');

return $result;

How code an integration formula using Python

<p>I have an integration equations to calculate key rate and need to convert it into Python. </p>
<p><strong>The equation to calculate key rate is given by:</strong></p>
<p><a href="https://i.stack.imgur.com/HLBeP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/HLBeP.png" alt="enter image description here"></a></p>

<p><strong>The key rate should be plotted like this:</strong></p>
<p><a href="https://i.stack.imgur.com/QZ1BP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QZ1BP.png" alt="enter image description here"></a></p>
<p>I have sucessfully plotted the static model of the graph using following equation:</p>
<pre><code>import numpy as np
import math
from math import pi,e,log
import matplotlib.pyplot as plt
n1=np.arange(10, 55, 1)
n=10**(-n1/10)
Y0=1*(10**-5)
nd=0.25
ed=0.03
nsys=nd*n
QBER=((1/2*Y0)+(ed*nsys))/(Y0+nsys)
H2=-QBER*np.log2(QBER)-(1-QBER)*np.log2(1-QBER)
Rsp=np.log10((Y0+nsys)*(1-(2*H2)))
print (Rsp)
plt.plot(n1,Rsp)
plt.xlabel('Loss (dB)')
plt.ylabel('log10(Rate)')
plt.show()
</code></pre>
<p>However, I failed to plot the R^ratewise model. This is my code:</p>
<pre><code>import numpy as np
import matplotlib.pyplot as plt
def h2(x):
return -x*np.log2(x)-(1-x)*np.log2(1-x)
e0=0.5
ed=0.03
Y0=1e-5
nd=0.25
nt=np.linspace(0.1,0.00001,1000)
y=np.zeros(np.size(nt))
Rate=np.zeros(np.size(nt))
eta_0=0.0015
for (i,eta) in enumerate(nt):
nsys=eta*nd
sigma=0.9
y[i]=1/(eta*sigma*np.sqrt(2*np.pi))*np.exp(-(np.log(eta/eta_0)+(1/2*sigma*sigma))**2/(2*sigma*sigma))
Rate[i]=(max(0.0,(Y0+nsys)*(1-2*h2(min(0.5,(e0*Y0+ed*nsys)/(Y0+nsys))))))*y[i]
plt.plot(nt,np.log10(Rate))
plt.xlabel('eta')
plt.ylabel('Rate')
plt.show()
</code></pre>
<p>Hopefully that anyone can help me to code the key rate with integration p(n)dn as stated above. This is the paper for referrence:
<a href="https://arxiv.org/pdf/1712.08949.pdf" rel="nofollow noreferrer">key rate</a></p>

Can't deploy webpack to gh-pages (react app)

<p>First time using webpack as well as deploying using gh-pages. I cloned a webpack project from a udemy course. Instructor doesn't get into how to actually use webpack. It's telling me that [etc.]/build doesn't exist. When I create a build folder, I get the same error.</p>

Remove duplicate on the basis of attribute value
|
<p>I want to remove duplicate array from the response on the basis of the attribute value. If the <code>attribute_value</code> data match with other array attribute value then other should be removed. </p>
<p>logic is very simple. check duplicate attribute_value in each array and remove duplicate array and return
In response. now you can see the attribute value = 1 is thrice
and attribute value = 2 is twice</p>
<p>How do i compare and remove whole array if I see attribute value duplicate?</p>
<p>I tried with filter method which seems not working. Please help.</p>
<pre><code>for(var j=0; j<social_post_link.length; j++){
newFilterarray = social_post_link[j].activity_attributes[0].attribute_value.filter(function(item, index) {
if (social_post_link[j].activity_attributes[0].attribute_value.indexOf(item) == index){
return social_post_link;
}
});

Xpages: Load field values on page when a value changes - bound to a bean
|
<p>Please see clarification at the botom of this email.</p>
<p>I have an Xpage where the user will choose an employee, after which a series of employee dependent fields should populate. I have done this before when my source was a document, but now I am using Objects. My object is bound to a java bean. </p>
<p><a href="https://i.stack.imgur.com/Hoeju.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Hoeju.jpg" alt="enter image description here"></a></p>
<p>For some reason I cannot get the on change event to fire when the Employee Name changes; at other times I can get the event to fire, but when I try to send the selection to a java method to load the values, I cannot get the value of the field. </p>
<p>What I think I have to do is put code in the onChange event of the employee field that grabs the value the user chose and then call a java method in my bean that will load the other employee values and then reload the panel. Boy, takes a long time even to write that! </p>
<p>Any help would be greatly appreciated. </p>

<p>============================</p>
<p>The issue I have is that when the user changes the value of employeeName the partial refresh does fire, BUT value that has been changed [employeeName] is not reflected in the backing bean. If I can do this, then everything will be fine.</p>

Why label of file size on filepond show 1kb every file when displaying edit form?
|
<p>I have a module that has add and edit form. In the add and edit form, the user can upload files. When edit, it will show uploaded files</p>
<p>In add form, it works. When user upload, file size of file displays file size correctly</p>
<p>But my problem is when edit form, each file displays 1kb file size on all files</p>
<p>You can see the problem here:</p>

<p>How can I solve this problem?</p>
<p>Note :</p>
<p>The docs : <a href="https://github.com/pqina/vue-filepond" rel="nofollow noreferrer">https://github.com/pqina/vue-filepond</a></p>
<p>Update :</p>
<p>I make my code in codesandbox like this : <a href="https://codesandbox.io/s/vue-filepond-live-demo-forked-0v3r3j" rel="nofollow noreferrer">https://codesandbox.io/s/vue-filepond-live-demo-forked-0v3r3j</a></p>
<p>Here it looks the same file size</p>
<p>Actually I can uncomment this script to solve my problem :</p>
<pre><code>file: {
name: this.filesFromApi[key].name,
size: this.filesFromApi[key].size,
},
</code></pre>
<p>But it makes me unable to fetch <code>metadata</code> in process. So <code>process</code> cannot be called. You can try it and see in the console log</p>

lapply and data.frame in R
|
<p>I am attempting to use R to accept as many user input files as required and to take those files and make one histogram per file of the values stored in the 14th column. I have gotten this far:</p>
<pre><code>library("tcltk")
library("grid")
File.names<-(tk_choose.files(default="", caption="Choose your files", multi=TRUE, filters=NULL, index=1))
Num.Files<-NROW(File.names)
test<-sapply(1:Num.Files,function(x){readLines(File.names[x])})
data<-read.table(header=TRUE,text=test[1])
names(data)[14]<-'column14'
dat <- list(file1 = data.frame("column14"),
file2 = data.frame("column14"),
file3 = data.frame("column14"),
file4 = data.frame("column14"))
#Where the error comes up
tmp <- lapply(dat, `[[`, 2)
lapply(tmp, function(x) {hist(x, probability=TRUE, main=paste("Histogram of Coverage")); invisible()})
layout(1)
</code></pre>
<p>My code hangs up though on the line that states <code>tmp <- lapply(dat,</code>[[<code>, 2)</code>
The error that comes up is one of two things. If the line reads as above then the error is this: </p>
<pre><code>Error in .subset2(x, i, exact = exact) : subscript out of bounds
Calls: lapply -> FUN -> [[.data.frame -> <Anonymous>
</code></pre>
<p>I did some research and found that it could be caused by a double [[]] so I changed it to <code>tmp <- lapply(dat,</code>[<code>, 2)</code> to see if it would do any good (as many tutorials said it might) but that just resulted in this error: </p>
<pre><code>Error in `[.data.frame`(X[[1L]], ...) : undefined columns selected
Calls: lapply -> FUN -> [.data.frame
</code></pre>
<p>The input files all will follow this pattern:</p>
<pre><code>Targ cov av_cov 87A_cvg 87Ag 87Agr 87Agr 87A_gra 87A%_1 87A%_3 87A%_5 87A%_10 87A%_20 87A%_30 87A%_40 87A%_50 87A%_75 87A%_100

</code></pre>
<p>Is this a common problem? Can anyone explain it to me? I am not too familiar with R but I hope to continue learning.
Thanks
EDIT:
For reproducibility, if I run:</p>
<pre><code>head(test)
head(data)
x <- list(mtcars, mtcars, mtcars);lapply(x, head)
head(dat)

Can't get Secret Santa code to memorize assigned names
|
<p>I am a newbie in Python, I've learned some basic things like data types, cycles and how functions work so far. The thing is I don't know anything about databases...<br />
I want to write a Secret Santa code to make a bot for me and my friends. The idea is that after you were invited to join the bot, you enter your name and surname and get assigned to a person (I need the surname part 'cos there are some people with the same name). After that the assigned name needs to be deleted from the initial 'targets' list, so it wouldn't be assigned to anyone else.
I've made the assignment part so far:</p>
<pre><code>def appointer(name, surname):
template = "You are {}'s Secret Santa, congrats!"
targets = ['George Orwell', 'Vladimir Nabokov', 'Vladimir Sorokin']
if name == 'George' and surname == 'Orwell':
targets.remove('George Orwell')
print(template.format(random.choice(targets)))
elif name == 'Vladimir' and surname == 'Nabokov':
targets.remove('Vladimir Nabokov')
print(template.format(random.choice(targets)))
elif name == 'Vladimir' and surname == 'Sorokin':
targets.remove('Vladimir Sorokin')
print(template.format(random.choice(targets)))
print(targets)
else:
print('Wrong name, check again!')
</code></pre>
<p>(I need separate names and targets lists 'cos in my language names are declined.)<br />
Yeah, that's how far I've got!<br />
So the next step is for the bot to remember the assigned name and remove it from the 'targets' list so when the next person uses the bot he or she doesn't get the same name.
I've tried to make the assigned names get into the separate list and stuff, but it doesn't work due to multiple 'if' cycles.<br />
So I've been wondering is there any way to get this thing done without resorting to databases?</p>
<p><strong>Here's an update:</strong></p>
<p>The plan to remember the assigned people via inbuilt dictionary didn't work and each time I run the code this dict resets to zero.<br />
Then I've found a very useful <em>shelve module</em>.
So here's the code I've made with Tom's help:</p>
<pre><code>import shelve
shelveFile = shelve.open('mydata')
import random
participants = [....]
template = "You're {}'s Secret Santa, congrats!"
def appointer(name, surname):
fullname = name + ' ' + surname
if fullname not in participants:
print("Wrong name, check again!)
return
if fullname in shelveFile.keys():
print("You already have your victim!")
return
options = [i for i in participants if i != fullname and i not in shelveFile.values()]
selection = random.choice(options)
shelveFile[fullname] = selection
print(template.format(selection))
if __name__ == '__main__':
appointer(name = input('Enter your name: ').lower().title(), surname = (input('Enter your surname:').lower().title()))
shelveFile.close()
</code></pre>
<p>Shelve module gives you an inbuilt database, and every time you run the code you still have the all the assigned people memorized.</p>

Send Form Value to Modal
|
<p>I have a form that asks for 3 fields. Once the form is submitted, it should open a modal. In the modal a budget summary should show. The budget summary data is pulled from a database and the values are based on the 3 form fields entered. I can't seem to get the values to show up in the modal so the query will work but, the modal does open.</p>
<p>Here is the modal code:</p>

StringBuilder with Caching, ThreadStatic
|
<p>I came across the code below from <a href="https://docs.microsoft.com/en-us/dotnet/framework/performance/writing-large-responsive-apps" rel="nofollow noreferrer">Writing Large, Responsive .NET Framework Apps</a>.</p>
<p>The code below creates a string like <code>SomeType<T1, T2, T3></code> using <code>StringBuilder</code>, and demonstrating caching <code>StringBuilder</code> to improve performance.</p>
<pre><code> public void Test3()
{
Console.WriteLine(GenerateFullTypeName("SomeType", 3));
}
// Constructs a name like "SomeType<T1, T2, T3>"
public string GenerateFullTypeName(string name, int arity)
{
//StringBuilder sb = new StringBuilder();
StringBuilder sb = AcquireBuilder();
sb.Append(name);
if (arity != 0)
{
sb.Append("<");
for (int i = 1; i < arity; i++)
{
sb.Append("T"); sb.Append(i.ToString()); sb.Append(", ");
}
sb.Append("T"); sb.Append(arity.ToString()); sb.Append(">");
}
//return sb.ToString();
/* Use sb as before */
return GetStringAndReleaseBuilder(sb);
}
[ThreadStatic]
private static StringBuilder cachedStringBuilder;
private static StringBuilder AcquireBuilder()
{
StringBuilder result = cachedStringBuilder;
if (result == null)
{
return new StringBuilder();
}
result.Clear();
cachedStringBuilder = null;
return result;
}
private static string GetStringAndReleaseBuilder(StringBuilder sb)
{
string result = sb.ToString();
cachedStringBuilder = sb;
return result;
}
</code></pre>
<p>However, is it correct that the two modified methods below are better in terms of caching StringBuilder?? Only AcquireBuilder needs to know how to cache it.</p>
<pre><code> private static StringBuilder AcquireBuilder()
{
StringBuilder result = cachedStringBuilder;
if (result == null)
{
//unlike the method above, assign it to the cache
cachedStringBuilder = result = new StringBuilder();
return result;
}
result.Clear();
//no need to null it
// cachedStringBuilder = null;
return result;
}
private static string GetStringAndReleaseBuilder(StringBuilder sb)
{
string result = sb.ToString();
//other method does not to assign it again.
//cachedStringBuilder = sb;
return result;
}
</code></pre>
<p>Another issue is that the original methods are not thread-safe, why is ThreadStatic used in the demo?</p>

How to get resovled value from $routeProvider in AngularJS?
|
<p>On change of views in my application i created resolve function which should find out if user is logged in or not: </p>
<pre><code> $routeProvider.
when('/taskoverview', {
templateUrl: 'Home/Template/taskoverview', resolve: TaskOverviewCtrl.resolve, access: { allowAnonymous: true },
resolve: {
userAuthenticated: ["$http", function ($http) {
var loggedIn;
$http.get('/api/Authentication/UserAuthenticated').then(function (data) {
if (data.data != null) {
loggedIn = true;
}
else {
loggedIn = false;
console.log("really");
}
});
return loggedIn;
}]
}
}).
otherwise({ redirectTo: '/' });
</code></pre>
<p>After it happend i want to check value of userAuthenticated on locationChangeStart, so i thought it should be pretty much straign forward.</p>
<pre><code>WorkerApp.run(function ($rootScope, $routeParams, $route, $location) {
$rootScope.$on('$locationChangeStart', function (event, next, current) {

event.preventDefault();
alert("no access");
}
}
}
}
});

Losing Gesture Recognizers in UIPopoverController
|
<p>I have a class called PhotoBoothController that I use to manipulate an image using gestures. It works fine when I run it on iPhone. However when I run it on iPad, I display the PhotoBoothController inside a UIPopoverController. The image appears fine, however I can't manipulate it as my gestures don't appear to be recognized. I'm not sure how to make the UIPopoverController take control of the gestures. </p>
<p>I present the popovercontroller and configure the view thus:</p>
<pre><code>- (void)presentPhotoBoothForPhoto:(UIImage *)photo button:(UIButton *)button {
//Create a photoBooth and set its contents
PhotoBoothController *photoBoothController = [[PhotoBoothController alloc] init];
photoBoothController.photoImage.image = [button backgroundImageForState:UIControlStateNormal];
//set up all the elements programmatically.
photoBoothController.view.backgroundColor = [UIColor whiteColor];
//Add frame (static)
UIImage *frame = [[UIImage imageNamed:@"HumptyLine1Frame.png"] adjustForResolution];
UIImageView *frameView = [[UIImageView alloc] initWithImage:frame];
frameView.frame = CGRectMake(50, 50, frame.size.width, frame.size.height);
[photoBoothController.view addSubview:frameView];
//Configure image
UIImageView *photoView = [[UIImageView alloc] initWithImage:photo];
photoView.frame = CGRectMake(50, 50, photo.size.width, photo.size.height);
photoBoothController.photoImage = photoView;
//Add canvas
UIView *canvas = [[UIView alloc] initWithFrame:frameView.frame];
photoBoothController.canvas = canvas;
[canvas addSubview:photoView];
[canvas becomeFirstResponder];
[photoBoothController.view addSubview:canvas];
[photoBoothController.view bringSubviewToFront:frameView];
//resize the popover view shown in the current view to the view's size
photoBoothController.contentSizeForViewInPopover = CGSizeMake(frameView.frame.size.width+100, frameView.frame.size.height+400);
self.photoBooth = [[UIPopoverController alloc] initWithContentViewController:photoBoothController];
[self.photoBooth presentPopoverFromRect:button.frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
}
</code></pre>
<p>I thought <code>[canvas becomeFirstResponder]</code> might do it but it doesn't appear to make a difference. </p>
<p>Any advice much appreciate, thank you. </p>

CSS floating and positioning
|
<p>I have 2 boxes that should show up next to eachother. I want one to have a vertical fixed position.
So when I scroll up or down the box stays at the same height. </p>
<p>But I don't want it to be horizontal fixed, because I want the 2 boxes together always in the center. Even when you make your browser bigger or smaller. For this I use the margin: 20px auto; </p>
<p>Is there any way <strong><em>how I can keep the margin and get 2 boxes where 1 of them has a vertical fixed position.</em></strong> </p>

How to re-index an AuditLog table? non clustered primary key, clustered covering index, guid
|
<p>Using SQL Server 2016 Standard. I have an existing <code>AuditLog</code> table, with a PK on a <code>bigint</code> column (generated C# side) and an additional index.</p>
<pre><code>CREATE TABLE [dbo].[AuditLog]
(
[Id] [bigint] NOT NULL,
[ChangeTime] [datetime] NOT NULL,
[User] [varchar](100) NOT NULL,
[RootId] [bigint] NOT NULL,
[EntityId] [bigint] NOT NULL,
[EntityName] [varchar](100) NOT NULL,
[Operation] [varchar](100) NOT NULL,
[OldValue] [varchar](max) NULL,
[NewValue] [varchar](max) NULL
)
ALTER TABLE [dbo].[AuditLog]
ADD CONSTRAINT [PK_AuditLog]
PRIMARY KEY CLUSTERED ([Id] ASC)
CREATE NONCLUSTERED INDEX [IX_AuditLog_RootId]
ON [dbo].[AuditLog] ([RootId] ASC)
</code></pre>
<p>With the current 105,000,000 rows, the sizes are (using used_page_count * 8K per page):</p>
<ul>
<li>PK_AuditLog: 11,535,112 KB</li>
<li>IX_AuditLog_RootId: 2,370,480 KB</li>
</ul>
<p>I now have to create rows in this table from a stored procedure in SQL, not in c# only anymore, so I need a primary key that can be generated SQL side (and C# still). I think my choices are <code>int identity</code> and <code>guid</code> (with a <code>NEWSEQUENTIALID</code> default).</p>
<p>Since most of my usages include the date and ordering by date, I'm thinking of clustering with that. Sounds right?</p>
<p>And since I almost always filter by <code>RootId</code> and <code>User</code>, I'm thinking of including them in my index. Is it a good idea to include the other columns in the clustered index? or should they be in a separate covering index?</p>
<p>Every index needs to identify rows uniquely, so my clustered index will include the primary key even if I don't specify it. So using a <code>Guid</code> as the PK seems a bad idea for storage, particularly with 100million rows. So I'm using a <code>bigint</code>.</p>
<p>Since my PK is notclustered (therefore not stored physically in that order), how does SQL Server work out the next identity? I doubt it sorts the PK to find the max value. Is using identity on a nonclustered column a bad idea?</p>
<p>Also, I guess I could use <code>datetime2</code> with precision 3 (storage 7 bytes) instead of <code>datetime</code> (8 bytes) to keep same precision but save a bit of space (or even precision 4 to increase precision for same storage anyway)?</p>
<p>So I'm thinking of doing:</p>
<pre><code>CREATE TABLE dbo.AuditLog
(
Id bigint NOT NULL IDENTITY (1, 1),
ChangeTime datetime2(4) NOT NULL...
ALTER TABLE AuditLog
ADD CONSTRAINT [PK_AuditLog]
PRIMARY KEY NONCLUSTERED (Id)
CREATE CLUSTERED INDEX CIX_AuditLog_ChangetimeRootUser
ON AuditLog(Changetime, RootId, [User])
</code></pre>
<p><strong>Footnote</strong></p>
<p>This is how the table is used:</p>
<ul>
<li><p>No foreign keys to or from this table.</p></li>
<li><p>insert heavy (any add/edit/delete of user entity fields inserts a new AuditLog row, constantly during business hours, must be fast)</p></li>
<li><p>occasional reads (users check what or who changed something, ie, read the AuditLog, a few times a day, would be nice to not wait ages for a query to return)</p></li>
<li><p>AuditLog rows are never updated nor deleted once inserted.</p></li>
</ul>
<p>Typical filters and order:</p>
<ul>
<li>filter by date only</li>
<li>filter by date and user</li>
<li>filter by date and objectId</li>
<li>filter by date and user and objectId</li>
<li>filter by objectId only </li>
<li>almost always sorted by reverse date, to show most recent changes first.</li>
<li>often used with paging, using "offset x rows" and "fetch next x rows only"</li>
<li>and a specific use case, which amounts to selecting a subset of PK using a where clause, and then self join on the main table using the PK to retrieve column values</li>
</ul>
<p>PS: I'm clear on the process and the time it will take, create temporary new table, copy data in chunks, create indexes, etc...</p>

App crashing because "It appears that 'PubNub' is not a valid Fabric Kit"
|
<p>Let me preface by saying that I'm using <code>CocoaPods</code> to manage my frameworks. I'm not sure if this really matters, but I thought you might as well know just in case. I'm also running on iOS 10.x with the latest version of Xcode (not beta).</p>
<hr>
<p>My app is crashing on <code>Fabric.with([Crashlytics.self, PubNub.self])</code> with the following error:</p>
<blockquote>
<p>Terminating app due to uncaught exception 'FABException', reason: '[Fabric] It appears that "PubNub" is not a valid Fabric Kit. Please make sure you only pass Fabric Kits to [Fabric with:].'</p>
</blockquote>
<p>I have updated my <code>PodFile</code>, cleaned my project, ran on a fresh install, ran on a physical and virtual device, and I've even uninstalled <code>pod 'PubNub'</code> and reinstalled it. Nothing seems to be working so far, so any help would be greatly appreciated. </p>
<p><strong>My <code>AppDelegate</code> looks like this:</strong></p>
<pre><code>import Fabric
import Crashlytics
import PubNub
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
/* Fabric (Answers) Debug */
Fabric.sharedSDK().debug = true
/* Fabric Setup */
Fabric.with([Crashlytics.self, PubNub.self])
return true
}
</code></pre>
<p><strong>My <code>PodFile</code> looks like this:</strong></p>

Use variables from one .as file in another?
|
<p>If I have created variables in one document named Main.as as follows:</p>
<pre><code>var backgroundLayer:Sprite = new Sprite;
var gameLayer:Sprite = new Sprite;
var interfaceLayer:Sprite = new Sprite;
</code></pre>
<p>How can I access these in another .as file? I'm trying to sort the objects in my game into layers but I'm getting errors. For example, I have a EnemyShip.as file with the following in it:</p>
<pre><code>function enterFrame(e:Event)
{
this.x -= speed;
if(this.x < -100)
{
removeEventListener("enterFrame", enterFrame);
stage.removeChild(this);
}
}
function kill()
{
var explosion = new Explosion();
stage.addChild(explosion);
explosion.x = this.x;
explosion.y = this.y;
removeEventListener("enterFrame", enterFrame);
stage.removeChild(this);
Main.updateScore(1);
shot.play();
}
</code></pre>
<p>The problem is I was trying to change <code>stage.addChild(explosion)</code> to <code>gameLayer.addChild(explosion)</code> but I got an <code>access of undefined property gameLayer</code> error. </p>
<p>There may be something obvious I am missing, so please let me know. I'm also not too sure whether I should be using <code>new Sprite</code> or <code>new Movieclip</code>; the majority of my game is made up of movie clips and buttons, so perhaps this should be changed?</p>
<p>Thanks.</p>

Can't seem to properly run python MSS library
|
<p>I am trying to learn the MSS python library to stream/reflect what's in the monitor. My intention is to use it with OpenCV to process the image. I got this source code from a youtube tutorial but I am getting the this error: (I can't solve this to run the code). Any tips and guidance are very much appreciated.</p>
<pre><code>Traceback (most recent call last):
File "C:\Users\Ryan Webb\Documents\OpenCV-objectDetection\mss.py", line 4, in <module>
from mss.windows import MSS as mss
File "C:\Users\Ryan Webb\Documents\OpenCV-objectDetection\mss.py", line 4, in <module>
from mss.windows import MSS as mss
ModuleNotFoundError: No module named 'mss.windows'; 'mss' is not a package
</code></pre>
<p>Here is the source code I copy-pasted from the tutorial:</p>
<pre><code>from mss import mss
import cv2
from PIL import Image
import numpy as np
from time import time
mon = {'top': 100, 'left':200, 'width':1600, 'height':1024}
sct = mss()
while 1:
begin_time = time()
sct_img = sct.grab(mon)
img = Image.frombytes('RGB', (sct_img.size.width, sct_img.size.height), sct_img.rgb)
img_bgr = cv2.cvtColor(np.array(img), cv2.COLOR_RGB2BGR)
cv2.imshow('test', np.array(img_bgr))
print('This frame takes {} seconds.'.format(time()-begin_time))
if cv2.waitKey(25) & 0xFF == ord('q'):
cv2.destroyAllWindows()
break
</code></pre>
<p>I think I properly installed the MSS library here is my pip list results:</p>

Measuring children in custom view breaks in RTL
|
<p>I have a custom view that extends LinearLayout and implements onMeasure. I'd like the children to be either as wide as they need to be or filling the available space.</p>
<p>XML files:
Parent:</p>
<pre class="lang-xml prettyprint-override"><code><FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.example.myapplication.AtMostLinearLayout
android:id="@+id/at_most_linear_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</FrameLayout>
</code></pre>
<p>Button example:</p>
<pre><code><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:layout_width="48dp"
android:layout_height="48dp"
android:layout_gravity="center"
android:src="@android:drawable/ic_delete" />
</FrameLayout>
</code></pre>
<p>Views are added programmatically, for example:</p>
<pre class="lang-kotlin prettyprint-override"><code> findViewById<AtMostLinearLayout>(R.id.at_most_linear_layout).apply {
repeat(4) {
LayoutInflater.from(context).inflate(R.layout.button, this)
}
}
</code></pre>
<p>Finally the Custom view class:</p>
<pre class="lang-kotlin prettyprint-override"><code>
class AtMostLinearLayout @JvmOverloads constructor(
context: Context,
attrs: AttributeSet? = null,
defStyle: Int = 0
) : LinearLayout(context, attrs, defStyle) {
private val maxTotalWidth = context.resources.getDimensionPixelOffset(R.dimen.max_buttons_width)
init {
orientation = HORIZONTAL
}
override fun onMeasure(widthMeasureSpec: Int, heightMeasureSpec: Int) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec)
if (childCount < 1) return
val newWidth = min(measuredWidth, maxTotalWidth)
var availableWidth = newWidth
var numberOfLargeChildren = 0
repeat(childCount) {
getChildAt(it).let { child ->
if (child.measuredWidth > availableWidth / childCount) {
availableWidth -= child.measuredWidth
numberOfLargeChildren++
}
}
}
val minChildWidth = availableWidth / max(childCount - numberOfLargeChildren, 1)
repeat(childCount) {
getChildAt(it).apply {
measure(
MeasureSpec.makeMeasureSpec(max(measuredWidth, minChildWidth), EXACTLY),
UNSPECIFIED
)
}
}
setMeasuredDimension(
makeMeasureSpec(newWidth, EXACTLY), makeMeasureSpec(measuredHeight, EXACTLY))
}
}
</code></pre>
<p>It works fine in LTR: <a href="https://i.stack.imgur.com/VmxJl.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/VmxJl.png" alt="Left to right screenshot" /></a>
In RTL however the views are off set for some reason and are drawn outside the ViewGroup: <a href="https://i.stack.imgur.com/67vZ6.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/67vZ6.png" alt="Right to left screenshot" /></a></p>
<p>Where could this offset coming from? It looks like the children's measure calls are being added to the part, or at least half of it...</p>

Enable all Select Options up to selectedIndex
|
<p>Greeting fellow code-jugglers!</p>
<p>I am dealing with a kinda frustrating problem, which it seems I can't solve to 100% I want it to work.</p>
<p>I've got a select field with various <strong>dynamic options amount</strong> (<em>could be more than one "middle", e. g. "middle 1", "middle 2"</em>) deactivated and fetched and build by php. The user has to input a number to activate and pre-select the specific select option. So far it works to the point, it pre-selects the option based on the user input. But I want it to enable <strong>every</strong> select option <strong>above</strong> the pre-selection.</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>$(document).ready(function() {
// PRE-SELECT TPOS BASED ON TMEMBER
$('#inputX').change(function() {
var member_id = $('#inputX').val();
// FETCHED BY PHP, NO NEED TO OVERRIDE (WORKS)
var event_id = <? echo $event_id; ?>;
var posit_id = <? echo $posit_id; ?>;
// FETCH CURRENT POSITION, MEMBER IS AT
$.ajax({
type: 'POST',

<option disabled="disabled" value="Last">Last</option>
</select>
</form></code></pre>
</div>
</div>
</p>
<p><strong>The returned value of AJAX is one of the option values, since my code needs them to be worked with and not integers as 1, 2 or 3(+).</strong></p>
<p><strong>For example:</strong>
I've got the same select field but the member with id number 3 is at position goal. So "<em>goal</em>", "<em>middle</em>", and "<em>start</em>" should be enabled. If member number 3 is at position middle, I want <strong>only</strong> "<em>start</em>" and "<em>middle</em>" to be enabled.</p>
<p>Any help?</p>
<p>Sincerely,
montreal</p>
<p><strong>EDIT</strong></p>
<p>Because of misunderstanding: ignore the AJAX. It just returns the value as position of the member, because the option value is defined as such --> E. G. Member with ID 1 is at position "middle", hence option value="middle" and everything <strong>before</strong> (option value="start") should be enabled.</p>
<p>I just want to enable every option based on the selectIndex from the returned value selected option minus total amount of options.</p>
<p>Example:
3 options
returned value is "middle", hence selectIndex 1
select option with selectIndex 0 and 1 should be enabled</p>

Can't fix Concurrency Violation VB/Access Database
|
<p>Cannot figure out how to resolve this issue. If I add rows to the database and close the form and then open the form an remove rows, I get no issues. The issue only arises when I add rows and remove rows without closing the form. What happens when the form closes that doesn't happen when the form is open?</p>
<p>If a box is checked, it gets added to the database. If a box gets unchecked it gets removed.</p>
<p>Concurrency violation: the DeleteCommand affected 0 of the expected 1 records.</p>
<p>Deleted row information cannot be accessed through the row.</p>

Figuring out the launch problem from the log

<p>This is very similar it seems, to
discover-why-godc-wont-start-on-mac but I Can't comment and what I have isn't an answer so
I'm opening a new question. </p>
<p>I have this problem where the Go Agent won't stay running on my Mac. It launches and then quickly exits. The log seems like a java issue but I have Java 8 and then also tried java 11, and neither worked. Here is the output of the log, but I cannot figure out if the version of Java is the issue or if it's something else. </p>

Garbage collecting in a ThreadPool?

<p>I need to handle http requests and the best way I found was using a ThreadPool. Please dont recommend using a finished library, because when I try to do something similar, there will be the same problem(s)!</p>

<p>When I stop the tool the memory usage still increases (see screenshot)!</p>
<p>I want the program to decrease its memory usage after the DDOS-Tool has been stopped.</p>
<p>But unfortunately it does not!</p>
<p>Here is my code: You can try it. It does not need any libraries!</p>

JsonSluper and JsonOutput convert some symbols in string to strange characters
|
<p>I am using a groovy script to convert some of the values in the body to their primitive datatype. To achieve this I am using JsonSluper and JsonOutput.
JsonSluper and JsonOutput are converting some symbols in string from my json body to strange characters. Any suggestions how this can be fixed ?</p>
<blockquote>
<p>Example: "UnitPrice": "99¢ per lb." is converted to "UnitPrice":
"99\u00a2 per lb."</p>
<p>¢ is converted to \u00a2</p>
</blockquote>
<p>My script:</p>
<pre><code>def body = message.getBody(java.lang.String);
def JSONInput = new JsonSlurper().parseText(body);
JSONInput.data.ProductStorePrices.each{
if(it.Price != null){
it.Price = it.Price.toDouble();
}
if(it.Active != null){
it.Active = it.Active.toBoolean();
}
}
message.setBody(JsonOutput.toJson(JSONInput))
</code></pre>
<p>Below is my JSONBody before conversion:</p>
<pre><code>{
"data": {
"ProductStorePrices": [
{
"Product_LegacyID": "1005",
"Store_LegacyStoreID": "2",
"DistributionCenter_LegacyRegionID": "916",

"LastChangedAt": "2022-05-04T23:59:59Z"
}
]
}
}

using boto3 in a python3 virtual env in AWS Lambda
|
<p>I am trying to use <strong>Python3.4</strong> and <strong>boto3</strong> to walk an <strong>S3</strong> bucket and publish some file locations to an <strong>RDS</strong> instance. The part of this effort I am having trouble with is when using boto3. My lambda function looks like the following:</p>
<pre><code>import subprocess

args = ("venv/bin/python3.4", "run.py")
popen = subprocess.Popen(args, stdout=subprocess.PIPE)
popen.wait()
output = popen.stdout.read()
print(output)
</code></pre>
<p>and, in my <strong>run.py</strong> file I have some lines:</p>

NotificationManager.notify locks the phone and Emulator
|
<p><strong>PROBLEM:</strong></p>
<p>The phone/emulator locks up on repeated Notification updates. The only way to get the emulator back responsive after it gets locked is by pressing Home => Menu => Lock => Home => Menu Button in that given order.</p>
<p><strong>CODE:</strong></p>
<p>Notification pushing code:</p>
<pre><code> // Set up notifcation views
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
NotificationManager notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE); // Get notification manager
RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.service_notification);
contentView.setViewVisibility(R.id.current_error_text, View.GONE);
contentView.setViewVisibility(R.id.error_text, View.GONE);
contentView.setViewVisibility(R.id.info_error_text, View.GONE);
contentView.setViewVisibility(R.id.info_text, View.GONE);
contentView.setViewVisibility(R.id.next_check_in_text, View.VISIBLE);
contentView.setViewVisibility(R.id.current_profile_text, View.VISIBLE);
contentView.setViewVisibility(R.id.profile_name_text, View.VISIBLE);
contentView.setTextViewText(R.id.next_check_in_text, mainText);
// Set profile text now
contentView.setTextViewText(R.id.profile_name_text, miniText);
// Set up a new notification
Notification notif = new Notification(R.drawable.service_logo_small, "Service is running", System.currentTimeMillis());
notif.contentView = contentView; // Set content view
// Create and plug in the PendingIntent
Intent notifIntent = new Intent(this, EntryPointActivity.class);
PendingIntent pIntent = PendingIntent.getActivity(this, 0, notifIntent, 0); // Set up the Pending Intent
notif.contentIntent = pIntent;
// Now set up notification flags
notif.flags |= Notification.FLAG_NO_CLEAR;
notif.flags |= Notification.FLAG_ONGOING_EVENT;
notif.flags |= Notification.FLAG_FOREGROUND_SERVICE;
if(sp.getBoolean("UpdateLights", true)) notif.flags |= Notification.DEFAULT_LIGHTS;
if(sp.getBoolean("UpdateVibrate", true)) notif.flags |= Notification.DEFAULT_VIBRATE;
if(sp.getBoolean("UpdateSound", true)) notif.flags |= Notification.DEFAULT_SOUND;
notificationManager.notify(R.string.app_name, notif);
</code></pre>
<p>All objects exist and the project compiles perfectly. I encounter NO NullPointerExceptions!</p>
<p>Code calling the notification creating function:</p>
<pre><code>final Timer timer = new Timer();
timer.scheduleAtFixedRate(new TimerTask(){
@Override
public void run() {
if(( nextUpdateIn - System.currentTimeMillis() ) > 0) {
long milliseconds = (nextUpdateIn - System.currentTimeMillis());
int seconds = (int) (milliseconds / 1000) % 60 ;
int minutes = (int) ((milliseconds / (1000*60)) % 60);
String toShow = "Next Check In: " + minutes + " minute" + ((minutes != 1) ? "s" : "") + " " + seconds + " second" + ((seconds != 1) ? "s" : "");
pushNotification(STATE_LOADEDSUCCESSFULLY, currentProfile.getProfileName(), toShow);
} else {
currentState = STATE_RELOADING;
pushNotification(STATE_RELOADING, null, "Refreshing..");
timer.cancel();
}
}
}, 1, 999);
</code></pre>
<p>Again, all objects exist!
The notification <strong>IS UPDATED</strong> in the above process but it locks up <strong>BOTH THE EMULATOR AND PHONE</strong> as mentioned above!</p>
<p><strong>AIM:</strong></p>
<p>To update notification in the Status Bar to basically show a countdown till the next refresh.</p>
<p>Please help me get rid of this error ASAP!</p>
<p>Thanks in advance :)</p>
<p>Regards,</p>
<p>Akshit Soota</p>
<p><strong>EDIT:</strong></p>
<p>I'm trying to run this code via a <strong>SERVICE</strong> and I've tried on emulators running Android 2.2, 2.3.3, 4.1 and all of them give me the same problem!</p>

How to update ScrollView Width after device rotation?
|
<p>I am following a <a href="https://www.youtube.com/watch?v=EKAVB_56RIU&t=617s" rel="nofollow noreferrer">tutorial</a> to create a swift app that adds a number of views to a scroll view and then allows me to scroll between them. I have the app working and understand it for the most part. When I change the orientation of the device the views width don't get updated so I have parts of more than one view controller on the screen? Does anybody know how to fix this? From my understanding I need to call something in the viewsDidTransition method to redraw the views. Any help would be greatly appreciated. Thanks!</p>
<p>Here is what I have so far:</p>
<pre><code>import UIKit
class ViewController: UIViewController {
private let scrollView = UIScrollView()
private let pageControl: UIPageControl = {
let pageControl = UIPageControl()
pageControl.numberOfPages = 5
pageControl.backgroundColor = .systemBlue
return pageControl
}()
override func viewDidLoad() {
super.viewDidLoad()
scrollView.delegate = self
pageControl.addTarget(self,
action: #selector(pageControlDidChange(_:)),
for: .valueChanged)
scrollView.backgroundColor = .red
view.addSubview(scrollView)
view.addSubview(pageControl)
}
@objc private func pageControlDidChange(_ sender: UIPageControl){
let current = sender.currentPage
scrollView.setContentOffset(CGPoint(x: CGFloat(current) * view.frame.size.width,
y: 0), animated: true)
}
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
pageControl.frame = CGRect(x: 10, y: view.frame.size.height - 100, width: view.frame.size.width - 20, height: 70)
scrollView.frame = CGRect(x: 0, y: 0, width: view.frame.size.width, height: view.frame.size.height - 100)
if scrollView.subviews.count == 2 {
configureScrollView()
}
}
private func configureScrollView(){
scrollView.contentSize = CGSize(width: view.frame.size.width*5, height: scrollView.frame.size.height)
scrollView.isPagingEnabled = true
let colors: [UIColor] = [.systemRed, .systemGray, .systemGreen, .systemOrange, .systemPurple]
for x in 0..<5{
let page = UIView(frame: CGRect(x: CGFloat(x) * view.frame.size.width, y: 0, width: view.frame.size.width, height: scrollView.frame.size.height))
page.backgroundColor = colors[x]
scrollView.addSubview(page)
}
}
override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
print("hello world")
}
}
extension ViewController: UIScrollViewDelegate {
func scrollViewDidScroll(_ scrollView: UIScrollView) {
pageControl.currentPage = Int(floorf(Float(scrollView.contentOffset.x) / Float(scrollView.frame.size.width)))
}
}

Check whether exists index k such that elements of array A[] moved clockwise make a reverse bitonic array
|
<p>Check whether exists index <code>0 <= k < n - 2</code> such that elements of array <code>A[]</code> moved clockwise by <code>k</code> indexes make a reverse bitonic array.
My approach to do it in <strong>O(n)</strong> time complexity:</p>
<pre><code>bool is_antibitonicable(int A[], int n) {
// returns if there is such index k that
// after moving clockwise k elements of array
// A[], that array is reverse bitonic
// - strictly decreasing then strictly
// increasing
if (n < 3)
return false;
// if is_increasing[i] == 1 means this part of A[] is increasing,
// == 0 means that part of A[] is decreasing, == -1 default
int is_increasing[3] = { -1, -1, -1 };
for (int i = 0, j; i < n - 1;) {
if (A[i] < A[i + 1]) { // if A[] is increasing
j = 0;
while (j < 3 && is_increasing[j] != -1)
j++;
if (j == 3)
return false;
is_increasing[j] = 1;
while (i < n - 1 && A[i] < A[i + 1])
i++;
}
else if (A[i] > A[i + 1]) { // check if decreasing
j = 0;
while (j < 3 && is_increasing[j] != -1)
j++;
if (j == 3)
return false;
is_increasing[j] = 0;
while (i < n - 1 && A[i] > A[i + 1])
i++;
}
else // sequence of A[] is neither increasing nor decreasing
return false;
}
// if A[] is only increasing/decreasing
if (is_increasing[1] == is_increasing[2])
return false;
// if A[] is increasing->decreasing->increasing check if increasing
// parts can be merged into one increasing sequence
if (is_increasing[0] == 1 && is_increasing[1] == 0 && is_increasing[2] == 1)
return (A[0] > A[n - 1]);
// decreasing->increasing->decreasing
if (is_increasing[0] == 0 && is_increasing[1] == 1 && is_increasing[2] == 0)
return (A[0] < A[n - 1]);
return true; // increasing -> decreasing or opposite
}

<p>I'd be very glad if someone could look at my solution and comment whether it seems correct or how to do it better, any feedback will be appreciated.</p>

How to deal with input=file / IFormFile two-way binding in Razor Pages
|
<p>I have an entity that has byte[] to store logos in the database as varbinary. But to use this model on a Razor Page, I have extended it and added a IFormFile property to receive the uploaded file.</p>
<pre><code>public class Company
{
public string Name { get; set; }
public byte[] Logo { get; set; }
}
</code></pre>
<pre><code>public class CompanyModel : Company
{
[DataType(DataType.Upload)]
[FromForm(Name = "UploadedLogo")]
public IFormFile UploadedLogo { get; set; }
}
</code></pre>
<p>And in a method I fetch this company from the database and set IFormFile accordingly:</p>
<pre><code>var response = await _companyService.GetByIdAsync(id);
if (response != null)
{
if (response.Logo != null)
{
using (var stream = new MemoryStream(response.Logo))
{
var formFile = new FormFile(stream, 0, stream.Length, response.Name, response.Name);
formFile.Headers = new HeaderDictionary()
{
new KeyValuePair<string, StringValues>("Content-Disposition", $"form-data; name=\"Company.UploadedLogo\"; filename=\"{response.Name}.png\""),
new KeyValuePair<string, StringValues>("Content-Type", "image/png"),
};
response.UploadedLogo = formFile;
}
}
return response;
}
</code></pre>
<p>And the UploadedLogo is populated and I bind that on Razor Page</p>
<pre><code><form method="post"
enctype="multipart/form-data"
data-ajax="true"
data-ajax-method="post"
data-ajax-begin="begin"
data-ajax-complete="completed"
data-ajax-failure="failed">
...
<div class="form-group row">
<div class="col-sm-2 text-right">
<label asp-for="@Model.Company.Logo" class="col-form-label"></label>
</div>
<div class="col-sm-9">
<input type="file" class="dropify" data-height="200"
asp-for="@Model.Company.UploadedLogo"
data-max-file-size="100K" data-allowed-file-extensions="png jpg jpeg" />
</div>
</div>
...
<div class="form-group modal-actions">
<input type="submit" class="btn btn-primary btn-icon-text btn-md btn-save-editing" value="Save" />
</div>
</form>
</code></pre>
<p>By the way, I am using <a href="https://github.com/JeremyFagis/dropify" rel="nofollow noreferrer">Dropify</a> as file upload plugin and <a href="https://github.com/aspnet/jquery-ajax-unobtrusive" rel="nofollow noreferrer">jquery-ajax-unobtrusive</a> library to handle post requests. Here is the post method:</p>
<pre><code>public async Task<CompanyModel> OnPostAsync(CompanyModel company)
{
CompanyModel result = new CompanyModel();
try
{
if (company.UploadedLogo != null)
company.Logo = await company.UploadedLogo.GetBytes();
var response = await _companyService.SaveAsync(company);
if (response != null)
result = response;
}
catch (Exception ex)
{
_Logger.LogException(ex);
}
return result;
}
</code></pre>
<p>Now here is the scenario:</p>
<ul>
<li>When I am adding a new company, I enter company name and browse a file from my computer, and save the data. I can see Uploaded logo in company model received in post request, which is then converted to byte[] and saved in database. Everything is fine. Below is the fiddler capture:
<a href="https://i.stack.imgur.com/WRHln.png" rel="nofollow noreferrer">Fiddler capture for INSERT</a></li>
<li><strong>Problem starts</strong> when I try to edit the company. I open the company, service fetches the data, convert byte[] to IFormFile and the data (name + logo) is shown on the form. I just edit the name, do not touch the logo and let it be as it is and hit save. At this point, the Uploaded logo is null in company model received in post request. Below is the fiddler capture:
<a href="https://i.stack.imgur.com/scUt4.png" rel="nofollow noreferrer">Fiddler capture for UPDATE</a></li>
</ul>
<p>I can see the difference in the posted requests captures clearly. The file is not there in the case of edit. But I don't know how to fix this. It has been a day I am hurting my brain on this, can anyone assist me on this please?</p>
<p><strong>UPDATE:</strong> Added fiddler captures as well.</p>

<p>Hello friends, How can I prevent the border from appearing when the welcome screen appears?
That means I want to see a border on the only main page. How can fix this on my code? I couldn't block the border during the welcome screen. I also added a picture of the desired situation. You can see it below. I am waiting for your help.

Using GoogleMock to avoid dependencies when testing a Card and a CardCollection class
|
<p>I'm learning about mocking and am reasonably new to the concepts. For the sake of learning, I'm implementing a <code>Card</code> class and a <code>CardCollection</code> class which depends on the <code>Card</code>. Therefore I've created a <code>MockCard</code> for testing the <code>CardCollection</code>.</p>
<p>Here's the <code>Card.h</code></p>
<pre><code> class ICard {
protected:
int rank_;
std::string suit_;
public:
ICard(int rank, std::string suit) : rank_(rank), suit_(std::move(suit)) {};
[[nodiscard]] virtual int getRank() const = 0;
[[nodiscard]] virtual std::string getSuit() const = 0;
friend std::ostream &operator<<(std::ostream &os, const ICard &c);
bool operator>(const ICard &other) const;
bool operator<(const ICard &other) const;
bool operator<=(const ICard &other) const;
bool operator>=(const ICard &other) const;
bool operator==(const ICard &other) const;
bool operator!=(const ICard &other) const;
};
class Card : public ICard {
public:
Card(int r, std::string s);
[[nodiscard]] int getRank() const override;
[[nodiscard]] std::string getSuit() const override;
};
</code></pre>
<p>The <code>MockCard.h</code></p>
<pre><code>#include "gmock/gmock.h"
class MockCard : public ICard {
public:
MockCard(int rank, std::string suit) : ICard(rank, std::move(suit)){};
MOCK_METHOD(int, getRank, (), (const, override));
MOCK_METHOD(std::string, getSuit, (), (const, override));
};
</code></pre>
<p>And <code>CardCollection.h</code>:</p>
<pre><code> #include "Card.h"
class CardCollection {
protected:
vector<ICard *> cards_;
public:
CardCollection() = default;
~CardCollection() = default;
explicit CardCollection(vector<ICard*> cards);
ICard* pop();
...
</code></pre>
<p>Here is my test:</p>
<pre><code>#include "gmock/gmock.h"
TEST(CardCollectionTests, TestPop) {
MockCard card1(6, "C");
std::vector<ICard*> cards({&card1});
CardCollection cc(cards);
// pop the card off the collection, cast to MockCard
auto* new_card = (MockCard*) cc.pop();
ASSERT_EQ(6, new_card->getRank());
}
</code></pre>
<p>The best test that I can think of is to verify that the Card is a 6 of clubs. But we can't use the <code>Card</code> class directly as this would introduce unwanted dependencies into the unit test. So I resolve to cast the <code>ICard*</code> returned from <code>CardCollection::pop</code> to a <code>MockCard*</code> type so that we can use the <code>getRank()</code> method and test that the value returned is a <code>6</code>. However, this is a <code>MockCard</code> not a <code>Card</code> so <code>getRank()</code> actually returns a <code>0</code> and the test fails.</p>
<p>How can I set the value returned by <code>MockCard::getRank()</code> to <code>6</code>? More generally, Are there any obvious pitfalls you can see in my approach to testing this behavior and if so, what would you implement as an alternative?</p>

c# UWP scan for music files
|
<p>I am implementing a music player for windows 10, and i am in a bit of a pickle at the library phase.</p>
<p>I am scanning for all the files in music library (plus optional folders the user selects) and i need to also get their tags (only need the title and artist, don't need complex details).</p>
<p>The problem is performance. Getting the music properties cost ALOT if you have a large media library. At the moment i am doing the following:</p>
<pre><code>private void UserControl_Loaded(object sender, RoutedEventArgs e)
{
Task.Factory.StartNew(async () =>
{
try
{
var files = await StorageHelper.GetFiles(KnownFolders.MusicLibrary);
List<LocalAudio> tempList = new List<LocalAudio>();
foreach (var file in files)
{
MusicProperties properties = await file.Properties.GetMusicPropertiesAsync();
var title = string.IsNullOrWhiteSpace(properties.Title) ? file.Name : properties.Title;
var artist = string.IsNullOrWhiteSpace(properties.Artist) ? file.Path : properties.Artist;
tempList.Add(new LocalAudio() { Title = title, FilePath = file.Path, Artist = artist, Duration = properties.Duration });
if (tempList.Count > 50)
{
await AddToLibrary(tempList);
tempList.Clear();
}
}
await AddToLibrary(tempList);
tempList.Clear();
}
catch (Exception ex)
{
//log exception here
}
});
}
private async Task AddToLibrary(List<LocalAudio> tempList)
{
await Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>
{
foreach (var item in tempList)
{
this.LocalFiles.Add(item);
}
});
}
</code></pre>
<p>Where "LocalAudio" is my audio model and this.LocalFiles is an ObservableCollection.
Also, the StorageHelper.GetFiles(StorageFolder) method returns an IEnumerable of StorageFiles (music files) (it's a recursive method to go in depth).</p>
<p>I am adding batches of 50 files on the dispatcher thread so i won't block the UI (i know, even if it is an async method running in a task that i started by fire-and-forget it still blocks the UI if i add them continuously...).</p>
<p>My question is: how can i optimize this better?
Any idea is good. I was thinking to scan them once and save the music properties (title, artist and duration) in a file and read that file on application start and just sync the filename with the data i have in that file (a dictionary or something and read the file and keep it in memory). Not sure how good this idea is.</p>
<p>Thank you for taking your time reading my silly questions :)</p>

Parse iOS SDK: Dynamic cell height for PFQueryTableViewController based on results from Query
|
<p><strong>Scenario</strong> </p>
<p>I have an app that downloads data from my parse.com database and displays it into a PFQueryTableViewController. The PFQTVC has multiple (6) prototype cells each with their own reuseIdentifier as well as most importantly, their own height. I am currently using the following design to find the correct height for each <code>indexPath.row</code>...</p>
<p><strong>Currently</strong></p>
<p><em>this works before enabling paging</em></p>
<p>Each cell is unique as each one displays different types of information. So I am checking for each <code>self.objects</code> by each unique quality they have.</p>
<pre><code>-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
// \!/ -trouble maker
PFObject *object = [self.objects objectAtIndex:indexPath.row];
NSString *orientation = object[@"orientation"];
NSNumber *height;
if ([orientation isEqual: @"left"] || [orientation isEqual: @"right"]) {
height = @400.0;
}
else if ([orientation isEqual: @"up"] || [orientation isEqual: @"down"]) {
height = @500.0;
}
else if (blah blah blah) {
//ect.
}
return [height floatValue];
}
</code></pre>
<p>This all works. That is, before I enable paging. </p>
<p><strong>When I enable paging</strong></p>
<p>Like most apps mine needs to be able to page through data, and that's what mine does. I set my <code>objectsPerPage</code> to 10 - <em>problem is, when I scroll down to that tenth cell and reload the next page...</em></p>
<pre><code>...reason: '*** -[__NSArrayM objectAtIndex:]: index 11 beyond bounds [0 .. 10]'
</code></pre>
<p><strong>Reason</strong></p>
<p>When it loads the next page, <code>self.objects</code> in heightForRowAtIndexPath is an NSArray that does not get loaded with the new objects. This is causing my app to crash and making me very frustrated.</p>
<p><strong>Question</strong></p>
<p>Does anybody know how to fix this issue? </p>
<p><strong>EDIT</strong> </p>
<pre><code>NSNumber *height;
if (indexPath.row > self.objects.count) {
height = @50.0;
}
else {
PFObject *object = [self.objects objectAtIndex:indexPath.row];
NSString *orientation = object[@"orientation"];
if ([orientation isEqual: @"left"] || [orientation isEqual: @"right"]) {
//HAS COMMENTS
if ([[object objectForKey:@"comments"]intValue] > 0) {
height = @618.0;
}
else {
//NO COMMENTS BUT HAS LIKES
if ([[object objectForKey:@"likes"]count] > 0) {
height = @398.0;
}
//HAS NOTHING
else {
height = @381.0;
}
}
}
else if ([orientation isEqual: @"up"] || [orientation isEqual: @"down"]) {
if ([[object objectForKey:@"comments"]intValue] > 0) {
height = @727.0;
}
else {
if ([[object objectForKey:@"likes"]count] > 0) {
height = @508.0;
}
else {
height = @490.0;
}
}
}
return [height floatValue];
}

Is Realm's .where faster than filtering a list manually?
|
<p>I am creating a project using a realm database.</p>
<p>I also have a lot of lists which I wish to filter while the user types.</p>
<p>The biggest one of them will probably be the list of customers</p>
<p>Currently I am using realm by using a wrapper class for each object (if anyone has a better suggestion I'm definitely open to it)</p>
<p>The objects I am using are like this:</p>
<pre><code>public class Customer_Realm extends RealmObject{
private int _id;
private String _name; //...etc
public int get_id(){ return _id; }
public void set_id(int id) { _id = id;}
//etc
}
Public class Customer() {
Customer_Realm _base;
public Customer(Customer_Realm base) { _base = base;}
public int get_id(){ return _base.get_id(); }
public void set_id(int id) { _base.set_id(id);}
//...etc
}
</code></pre>
<p>Along with this I have an ArrayListAdapter for customer objects. My question is, would this:</p>
<pre><code>public class CustomerAdapter extends ArrayListAdapter<Customer> {
List<Customer> _customers;
String _filter = null;
public void set_filter(string name) {
_filter = name;
notifyDataSetChanged();
}
@override
public int getCount(){
return get_visible().count();
}
public Customer getItem(int position){
return get_visible().get(position);
}
public List<Customer> get_visible() {
if (_filter == null)
return _customers;
List<Customer> visible = new ArrayList<Customer> ();
foreach (Customer c : _customers){
if (c.get_name().contains(_filter)
visible.add(c);
}
return visible;
}
}
</code></pre>
<p>Or would this be better?</p>
<pre><code>public class CustomerAdapter extends ArrayListAdapter<Customer> {
Realm _database;
String _filter = null;
public void set_filter(string name) {
_filter = name;
notifyDataSetChanged();
}
@override
public int getCount(){
return get_visible().count();
}
public Customer getItem(int position){
return get_visible().get(position);
}
public List<Customer> get_visible() {
RealmResults<Customer_Realm> result = null;
if (_filter == null)
result = _database.allObjects(Customer_Realm.class);
else
result = _database.where(Customer_realm.class).contains("_name",_filter);
List<Customer> visible = new ArrayList<Customer> ();
foreach (Customer_Realm c : result){
visible.add(new Customer(c));
}
return visible;
}
}
</code></pre>
<p>Unfortunately my database contains only a small sample of data(and realm for windows does not have an editor so I can enter data manually) so when I try either implementation I do not see any difference, I was wondering if anyone has any experience with what happens when you use such an implementation with a large number of data</p>

Listview doesn't gives correct values
|
<p>I'm getting wrong values from the Listview after clicking on it.</p>
<p><strong>Flow:</strong></p>
<p>a)I have a Spinner once Spinner selected the Listview values gets changed using the help of an Asynctask.</p>
<p>OnPostMethod Method of Asynctask to load items in the Listview</p>
<pre><code>protected void onPostExecute(List<MIC_OrderDetails> lst) {
dialog.setMessage("Inflating Data...");
if (lst.get(lst.size() - 1).getResult().contains(("success"))) {
ordList.addAll(lst);
ordList.notifyDataSetChanged();
dialog.dismiss();
/*

* lstView.setAdapter(ordList);

<p>In My Adapter MicListAdapter i have created addAll() method since direct invocation doesn't work for me</p>

this.alllst.addAll(lst);
this.notifyDataSetChanged();
}
</code></pre>
<p>b)OnClicking the Listview the values corresponds to it doesn't comes in my Custom Dialog box ie</p>
<p>Suppose my Spinner contains two values(1 & 2).By default at the first time 1 will be shown in the Spinner when i changed it to 2 the Listview values gets affected that corresponds to "2" but when i clicked on the Listview the values that i got belongd to "1".</p>

LabeledPieChart: Style overrides DataTemplate
|
<p>I have customized the template of LabeledPieChart (source: <a href="http://bea.stollnitz.com/blog/?p=438" rel="nofollow">Bea</a>) in a Style. Then I created a DataTemplate for the Slices of the LabeledPieChart. Both the style and the DataTemplate works great if they are alone. If they are together the Style overrides the DataTemplate that he has no effect. Is it possible to combine these two?

Reading and Writing with Multiple Children C++ Unix
|
<p>So, this is a follow up on my assignment I posted earlier.
Link: <a href="https://stackoverflow.com/questions/42913617/piping-and-forking-in-c-in-unix">https://stackoverflow.com/questions/42913617/piping-and-forking-in-c-in-unix</a></p>
<p>Got that section of the code all working now, but now I have to move onto 4 processes, which is giving me a hard time. Just as a recap, I have to take data files and have the sum of the integers added up using piping and forking. Currently I am having problems getting the sum to come up, if I put int mypipe[4] and change all my variables accordingly, my program freezes up. Currently trying two pipes, but only will show the sum of one of the pipes. Here is my code I have for the 4 process portion: </p>
<pre><code>else
{
pid_t child1, child2, child3, child4;
int mypipe1[2];
int mypipe2[2];
//File 1
t1=clock();
int temptotal=0;
int file1[1000];
for(int i = 0; i < 1000; i++)
{
infile1 >> file1[i];
}
pipe(mypipe1);
pipe(mypipe2);
//Begin the forking
if((child1 = fork()) == 0)
{
close(mypipe1[1]);
close(mypipe2[0]);
close(mypipe2[1]);
for(int i = 0; i < 250; i++)
{
temptotal = temptotal + file1[i];
}
write(mypipe1[0], &temptotal, sizeof(temptotal));
temptotal=0;
exit(0);
}
else
{
if((child2 =fork())==0)
{
close(mypipe1[0]);
close(mypipe2[1]);
close(mypipe2[0]);
for(int i =250; i < 500; i++)
{
temptotal = temptotal + file1[i];
}
write(mypipe1[1], &temptotal, sizeof(temptotal));
temptotal=0;
exit(1);
}
else
{
if((child3=fork())==0)
{
close(mypipe1[0]);
close(mypipe1[1]);
close(mypipe2[1]);
for(int i =500; i < 750; i++)
{
temptotal = temptotal + file1[i];
}
write(mypipe2[0], &temptotal, sizeof(temptotal));
temptotal=0;
exit(0);
}
else
{
if((child4=fork())==0)
{
close(mypipe1[0]);
close(mypipe1[1]);
close(mypipe2[0]);
for(int i =750; i < 1000; i++)
{
temptotal = temptotal + file1[i];
}
write(mypipe2[1], &temptotal, sizeof(temptotal));
temptotal=0;
exit(1);
}
else
{
//Parent Proccess
int n1,n2,n3,n4;

std::cout<<"File1 sum: "<<total<<std::endl;

Google Places not returning complete results with RouteBoxer
|
<p><strong>EDIT: It seems that I'm hitting the query limit, but I'm not being returned a full 200 results. So upon further research it looks like the Google API will let me query 10 boxes, return those results, and then smacks me with an OVER_QUERY_LIMIT status for the rest. So I figure I now have two options: slow my queries, or broaden my distance to create fewer boxes along the route.</strong></p>
<p>I'm currently fooling around building a little web app that provides a details about places along a route (like gas stations and coffee on a road trip). I'm using the Google Maps API with the Places Library and <a href="https://google-maps-utility-library-v3.googlecode.com/svn/trunk/routeboxer/docs/examples.html" rel="nofollow">RouteBoxer</a>. <strong>I'm generating all the appropriate boxes with RouteBoxer, but when the boxes are passed to the Places Library I'm only getting back some of the places.</strong> Usually I'll get the first half of the route (on shorter routes) or a few random chunks (for longer routes). San Francisco to Seattle returns me gas stations around Seattle and around Medford, OR only.</p>
<p>Initially I thought maybe I was hitting the results cap of 200, but it's making a separate request for each box, and my total results often aren't hitting 200. Results returned are generally pretty consistent from what I can see. When looking at the details of my network requests and responses, it seems that the script is moving through the boxes making requests with the Places library, and suddenly it stops part way through.</p>
<p>The live app where you can see results and boxes is on <a href="https://arcane-island-6450.herokuapp.com/" rel="nofollow">Heroku</a>.</p>
<p>My JavaScript isn't the strongest by any means. That's part of why I wanted to work with this API, so please pardon my ignorance if I'm making a trivial mistake. The full script is below. Any direction is tremendously appreciated!</p>

How to use SQLAlchemy models to generate raw SQL which is able to create all tables?
|
<p>It is possible to generate raw SQL statement to create any SQLAlchemy table <a href="https://stackoverflow.com/questions/2128717/sqlalchemy-printing-raw-sql-from-create">as shown here</a>.</p>
<p>However, I would like to generate raw SQL which creates all tables, not just one.</p>
<p>Let's assume I have such tables (this table design is not real-world, but it shows the issue well):</p>
<pre class="lang-py prettyprint-override"><code>import sqlalchemy
from sqlalchemy import Column, Integer, Text, ForeignKey
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.schema import CreateTable
from sqlalchemy.dialects import postgresql
engine = sqlalchemy.create_engine('postgresql://postgres:postgres@127.0.0.1:5432/postgres', echo=True)
Base = declarative_base()
class Product(Base):
__tablename__ = "product"
id = Column(Integer, primary_key=True, autoincrement=True)
name = Column(Text, nullable=True)
user_id = Column(Integer, ForeignKey('user.id'), nullable=True)
class User(Base):
__tablename__ = "user"
id = Column(Integer, primary_key=True, autoincrement=True)
name = Column(Text, nullable=True)
product_id = Column(Integer, ForeignKey('product.id'), nullable=True)
open("create_tables.sql", 'w').close() # to clear the file
for table in Base.metadata.tables.values():
table_sql = str(CreateTable(table).compile(dialect=postgresql.dialect()))
with open("create_tables.sql", "a") as myfile:
myfile.write(table_sql)
Base.metadata.create_all(engine)
</code></pre>
<p>(this is complete program, you can run it as-is)</p>
<p>In code above you can see that I use <code>for</code> loop to generate raw SQL:</p>
<pre class="lang-py prettyprint-override"><code>for table in Base.metadata.tables.values():
table_sql = str(CreateTable(table).compile(dialect=postgresql.dialect()))
with open("create_tables.sql", "a") as myfile:
myfile.write(table_sql)
</code></pre>
<p>Resulting file contains:</p>
<pre class="lang-sql prettyprint-override"><code>CREATE TABLE product (
id SERIAL NOT NULL,
name TEXT,
user_id INTEGER,
PRIMARY KEY (id),
FOREIGN KEY(user_id) REFERENCES "user" (id)
)
CREATE TABLE "user" (
id SERIAL NOT NULL,
name TEXT,
product_id INTEGER,
PRIMARY KEY (id),
FOREIGN KEY(product_id) REFERENCES product (id)
)
</code></pre>
<p>But I can't execute this SQL code, it will give me error due to circular reference. (and I need to add at least some <code>;</code>)</p>
<hr />
<p>SQLAlchemy can however create those tables without problem when I use:</p>
<pre class="lang-py prettyprint-override"><code>Base.metadata.create_all(engine)
</code></pre>
<p>With <code>echo=True</code> the generated SQL is visible in log:</p>

Is there a way to store pipeline stages in sklearn?
|
<p>I am about to create a simple model-pipeline using sklearn´s pipeline module:</p>
<pre><code>from sklearn.feature_extraction.text import TfidfVectorizer
from sklearn.base import BaseEstimator, TransformerMixin
from sklearn.decomposition import TruncatedSVD
from sklearn.linear_model import LogisticRegression
class TextTransformer(BaseEstimator, TransformerMixin):
def __init__(self, key):
self.key = key
def fit(self, X, y=None, *parg, **kwarg):
return self
def transform(self, X):
return X[self.key]
X_train, X_test, y_train, y_test = train_test_split(df[['text']],
df['target'],
test_size=0.20)
feature_pipeline = Pipeline([
('transformer', TextTransformer(key='text')),
('tfidf', TfidfVectorizer(ngram_range=(1,1))),
('svd', TruncatedSVD(algorithm='randomized', n_components=150))
])
pickle.dump(feature_pipeline, open(../".pkl", 'wb'))
</code></pre>
<p>After initializing the feature selection, <code>feature_pipeline</code>, I´d like to call the created pipe on several models from other scripts, like (SVC as an example):</p>
<pre><code>svc_pipeline = Pipeline([('features', feature_pipeline),
('SVC',SVC())
])
parameter_grid = {'SVC__kernel':['linear','rbf'],
'SVC__C':loguniform(1e-1, 1e2),
'SVC__gamma':loguniform(1e-3, 1e0)}
svc_pipeline = RandomizedSearchCV(svc_pipeline, parameter_grid, n_iter = 10, cv=5,n_jobs = -1))
svc_pipeline.fit(X_train, y_train)
predictions = svc_pipeline.predict(X_test)
</code></pre>
<p>So far, I´ve initialized each model in the same fashion and I´d assume the <code>feature_pipeline</code> has to be initialized for each model separately?!</p>
<p>As a workaround, I currently pickle the fitted <code>feature_pipeline</code>, transform and store the X_train, X_test matrices, like:</p>
<pre><code>feature_pipeline.fit(X_train)
pickle.dump(feature_pipeline, open(../".pkl", 'wb'))
X_train_transformed = feature_pipeline.transform(X_train)
pickle.dump(X_train_transformed, open(../".pkl", 'wb'))
X_test_transformed = feature_pipeline.transform(X_test)
pickle.dump(X_test_transformed, open(../".pkl", 'wb'))
</code></pre>
<p>Is there a way to save the <code>feature_pipeline</code> directly so that it can be utilized without the need of applying this workaround? Or is there any other best practice?</p>

Upload Image to URI using HttpClient

<p>I´m a newbie about http related things, so I am a little stacked.</p>
<blockquote>
<p>What I want is simple, I need to POST, upload a imaged to a server like this: <code>http://web.com/imageGalerry</code> . </p>
</blockquote>
<p>I think its not too much complicated <strong>but I dont know why I am no getting errors</strong> and so far now I´m not sure how to continue(because the image is not upload in fact), this is my code:</p>

MultipartFormDataContent multiForm = new MultipartFormDataContent();
try
{
using (var client = new HttpClient())
{
using (var br = new BinaryReader(file.OpenReadStream()))
{
data = br.ReadBytes((int)file.OpenReadStream().Length);
}
bytes = new ByteArrayContent(data);
multiForm.Add(bytes, "file", file.FileName);
//multiForm.Add(new StringContent("value1"), "key1");
//multiForm.Add(new StringContent("value2"), "key2");
var res = await client.PostAsync(urlToPost, multiForm);
return res;
}
}
catch (Exception e)
{
throw new Exception(e.ToString());
}

</code></pre>
<p>This is the view:</p>
<pre class="lang-html prettyprint-override"><code><form action="/Galley/UpdateGallery" method="post" class="dropzone" id="myDropzone">
<input type="hidden" value="1" name="idResource" />
</form>
</code></pre>
<p>and the dropzone js I am using to handle the view:</p>
<pre class="lang-js prettyprint-override"><code>document.addEventListener("DOMContentLoaded", function () {
// access Dropzone here
//dropzone.js detecta la version 'camelized' cuando el div tiene la clase dropzone
Dropzone.options.myDropzone = {
addRemoveLinks: true,

.....
}
</code></pre>
<blockquote>
<p>And this is the error code I get from <code>return res</code></p>

TableView does not load realm database values
|
<p>I have used <strong>XMPPFramework</strong>, since the user authentication and receiving only messages is done using XMPP. I am sending messages using <strong>RestApi</strong>. I have parsed the received xml message using <strong>SwiftyXMLParser</strong> library and now I have to store 'senderName', 'messageBody', 'time', 'senderNumber' in <strong>Realm</strong> database. </p>
<p>Initially the tableView in ContactsViewController is empty. When user sends the message, It will first get stored in database and then I have to show the sender's Number/Name and messageBody in the tableViewCell. If same user sends the message just update the messageBody text. If different user sends the message, check if user exists in db, if not, add the user in the tableView and so on... check user for every message and likewise populate the tableView.</p>
<p>Here is what I have done so far:</p>
<pre><code>class ContactsViewController: UIViewController, UITableViewDelegate, UITableViewDataSource{
var messagesArray:[String] = [String]()
var messageBody : [String] = [String]()
var realm : Realm!
var userInfo = MessageData()
// viewDidLoad() // assign tableView delegate, datasource and register the Nib.
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return messagesArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = contactsTableView.dequeueReusableCell(withIdentifier: "contactscell", for: indexPath) as! ContactsListCell
cell.userNameLabel.text = messagesArray[indexPath.row]
cell.userImageView.image = UIImage(named: "default-user")
cell.messageBodyLabel.text = messageBody[indexPath.row]
return cell
}
} // end of class
extension ContactsViewController: XMPPStreamDelegate {
func xmppStream(_ sender: XMPPStream, didReceive message: XMPPMessage) {
let string = message.prettyXMLString()
let xml = try! XML.parse(string!)
let messageSenderNo = xml["message"]["data”][“phoneNumber”].text
let senderName = xml["message"]["data”][“name”].text
let messageText = xml["message"]["data”][“text”].text
let messageTime = xml["message"]["data"]["time"].text
userInfo.messageFrom = messageSenderNo
userInfo.messageBody = messageText
userInfo.senderName = senderName
realm = try! Realm()
try! realm.write {
realm.add(userInfo, update: true)
}
let senderOfMsg:[String] = realm.objects(MessageData.self).value(forKey: "messageFrom") as! [String]!
let textMessage:[String] = realm.objects(MessageData.self).value(forKey: "messageBody") as! [String]!
messagesArray = senderOfMsg
messageBody = textMessage
}
}
</code></pre>
<p>This is my <strong>Message</strong> Class:</p>
<pre><code>class MessageData: Object{
dynamic var messageFrom:String = ""
dynamic var messageBody:String = ""
dynamic var messageTime:String = ""
dynamic var messageSenderName:String = ""
override static func primaryKey() -> String? {
return "messageFrom"
}
convenience init(messageFrom: String, messageBody: String, messageSenderFirstName: String, messageSenderLastName: String, message_id: String, messageTime: String){
self.init()
self.messageFrom = messageFrom
self.messageBody = messageBody
self.messageTime = messageTime
self.messageSenderName = messageSenderName
}
}
</code></pre>
<p>I am using Realm for first time, so I don't know If I have done some fatal mistake. If at all the data gets saved in the realm database. For the first time tableView should be blank , but after there is data in the database, the tableView must show the contacts and messageBody. It should show previous messages if any, just like <em>WhatsApp</em> when user launches the app again. The data in the tableView should persist. Please tell me what I am doing wrong or have not done. Thank you for your time.</p>

Clients using `GET` requests for a form, even though `POST` is defined. is javascript iframe the cause?
|
<p>I have two subsequent forms on my website with POST method.</p>
<p>The first page of my website <code>first.php</code> contains this code:</p>
<pre><code><form action="a.php" method="POST" target="_blank">
<input name="value" type="hidden" value="foo"/>
<div class="button"><label><span class="icon"></span>
<input type="submit" class="button-graphic ajax" value="Click Here"></label></div></form>
</code></pre>
<p><code>a.php</code> can be accessed only via this POST request (otherwise user will get method not allowed 405 error)</p>
<p>Once submitted, this form opens <code>a.php</code> with an AJAX modal window.</p>
<p><code>a.php</code> contains another form:</p>
<pre><code><form action="b.php" method="POST" target="_blank">
<input name="bar" type="hidden" value="none"/>
<div class="border"><label><input type="submit" class="button-graphic2 tracking" value="Continue"></label></div></form>
</code></pre>
<p>When a user clicks Submit in the second form, it will open <code>b.php</code>,
which can also be accessed only via POST request (otherwise - 405 error).</p>
<p>The only difference I can think about between these forms is that the second one contains a tracking js class (opening an iframe). this is the js code:</p>
<pre><code>$(document).ready(function() {
$(".tracking").click(function(){
var iframe = document.createElement('iframe');
iframe.style.width = '0px';
iframe.style.height = '0px';
iframe.style.display = 'block';
document.body.appendChild(iframe);
iframe.src = '/track.htm';
});
</code></pre>
<p>This is done in order to track a conversion using a third party script which is being execuated from <code>track.htm</code></p>
<p>I noticed that I am having a problem with about 5% of my iPad visitors.
they open <code>a.php</code> properly with a POST request, but when they go ahead to continue and open <code>b.php</code> as well, about 5% sends out a <code>GET</code> request instead of the desired <code>POST</code> request, causing them to get an 405 error and leave the website.</p>
<p>I know that these are real human users as I can see some of them trying several times to open <code>b.php</code> and keep getting these 405 errors.</p>
<p>Could this be caused because simultaneously their device is using a <code>GET</code> request to obtain <code>track.htm</code>? and this is some glitch?</p>
<p>How can this be solved?</p>
<p><strong>EDIT 4.4.2015:</strong></p>
<p>Since there's a chance that firing the tracking script is causing this, I would like to know if there's another fire to fire it (or track that adwords conversion), without causing these iPad user to use "GET" requests for the form as well.</p>
<p><strong>EDIT 10.4.2015</strong>:</p>
<p>This is the jquery code of the <code>ajax</code> class, that effects both <code>first.php</code> and perhaps <code>a.php</code>, as <code>first.php</code> is the parent frame:</p>
<pre><code>$(document).ready(function() {
$(".ajax").click(function(t) {
t.preventDefault();
var e = $(this).closest("form");
return $.colorbox({
href: e.attr("action"),
transition: "elastic",
overlayClose: !1,
maxWidth: $("html").hasClass("ie7") ? "45%" : "false",
opacity: .7,
data: {
value: e.find('input[name="value"]').val(),
}
}), !1
})
}),

Python Catching Popen Output
|
<p>I'm experiencing some strange behavior with my Python script exiting without any error messages. Based on my debugging it is happening around a popen() call to scp a file to a server.</p>
<p>The code was (I was not the original author):</p>
<pre><code>logMessage(LEVEL_INFO, "copyto is " + copyto)
pid = Popen(["scp", "-i", "/root/.ssh/id_rsa", "/usr/gpsw/gpslog" + self.node_addr, copyto], stdout=PIPE)
__s = pid.communicate()[0]
logMessage(LEVEL_INFO, "GPS log SCP complete")
</code></pre>
<p>In an attempt to debug I enhanced it to:</p>
<pre><code>logMessage(LEVEL_INFO, "copyto is " + copyto)
pid = Popen(["scp", "-i", "/root/.ssh/id_rsa", "/usr/gpsw/gpslog" + self.node_addr, copyto], stdout=PIPE, stderr=PIPE)
out, err = pid.communicate()
if out:

</code></pre>
<p>Here is my console output:
(The pattern should be 5dda77, 5dd9fa, 5dda0d repeatedly. This is based on physical events)</p>
<pre><code>[5dda77] returncode of pid: 0
[5dd9fa] returncode of pid: 0
[5dda0d] returncode of pid: 0
[5dda77] returncode of pid: 0
[5dd9fa] returncode of pid: 0
[5dda0d] returncode of pid: 0
# (the script exited and I'm back at the prompt)
</code></pre>
<p>And here is my log output:</p>
<pre><code>INFO copyto is root@192.168.20.1:/usr/scu/datafiles/gpslog5dda77
INFO GPS log SCP complete
INFO copyto is root@192.168.20.1:/usr/scu/datafiles/gpslog5dd9fa
INFO GPS log SCP complete
INFO copyto is root@192.168.20.1:/usr/scu/datafiles/gpslog5dda0d
INFO GPS log SCP complete
INFO copyto is root@192.168.20.1:/usr/scu/datafiles/gpslog5dda77
INFO GPS log SCP complete
INFO copyto is root@192.168.20.1:/usr/scu/datafiles/gpslog5dd9fa
INFO GPS log SCP complete
INFO copyto is root@192.168.20.1:/usr/scu/datafiles/gpslog5dda0d
INFO GPS log SCP complete
INFO copyto is root@192.168.20.1:/usr/scu/datafiles/gpslog5dda77
</code></pre>
<p>So based on the log and output data. I believe something is going wrong during the SCP because the Python script crashes before it logs "GPS log SCP complete". What is interesting though is I see on the server end the file was copied entirely. So two questions:</p>
<ol>
<li>Am I using popen incorrectly?</li>
<li>Why am I not seeing any error messages in stderr?</li>
</ol>
<p>Thanks </p>
<p><strong>EDIT:</strong>
This script should <em>never</em> exit. There is no "normal exit" of the process. It should run indefinitely servicing requests from the server to retrieve data from GPS nodes that are available. </p>
<p>The main loop code is:</p>
<pre><code>stop_flags = 0
... (API for server and GPS nodes to interact with)
def main():
... (System initialization)
while stop_flags == 0:
# listen for messages
xmlrpcserver.handle_request()
comm.poll()
if stop_flags == STOP_FLAG_RESTART:
# suppress Pylint warning for reimport of Popen,PIPE
# pylint: disable-msg=W0404
from subprocess import Popen, PIPE
# use this instead of call to suppress output
pid = Popen(["/etc/init.d/S999snap",
"restart"],
stdout=PIPE)
__s = pid.communicate()[0]
if stop_flags == STOP_FLAG_REBOOT:
# suppress Pylint warning for reimport of Popen,PIPE
# pylint: disable-msg=W0404
from subprocess import Popen, PIPE
# use this instead of call to suppress output
pid = Popen(["reboot"],
stdout=PIPE)
__s = pid.communicate()[0]
if __name__ == '__main__':
main()

<p>I have a graphical user interface for my company product.
I want to secure the data being sent back and forth between client and server.</p>
<p>Is SSL one of the options? if yes, Please can some1 tell me the steps on how to implement it in my application code. </p>
<p>Do i need to buy the certificate or can i make it.. which is the best choice?</p>
<p>Any help is appreciated. thanks..</p>
<p>I am logging in using FormsAuthenticationTicket as follows:</p>
<pre><code>Session["userName"] = UserName.Text;
Session["password"] = Password.Text;
Session["domain"] = Domain.Text;

// Create the authentication ticket
FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(1, // version
UserName.Text, // user name
DateTime.Now, // creation
DateTime.Now.AddMinutes(60),// Expiration
false, // Persistent

// Now encrypt the ticket.
string encryptedTicket = FormsAuthentication.Encrypt(authTicket);
// Create a cookie and add the encrypted ticket to the

HttpCookie authCookie =
new HttpCookie(FormsAuthentication.FormsCookieName,

Trying to filters an array of objects by an array of numbers with find my index and forEach doesnt work

<p>Im trying to filter all the contact I have with an array of numbers I want to remove. This should loop on every contact and remove the numbers not needed. Some contacts have two numbers and only one could be deleted but not the hole contact.

Little changes in the given algorithm
|
<p>It's about changing a maze algorithm.</p>
<p>What I mean by that? We got a 2-dimensional array filled with 0 and 1 where 0 stands for "not possible to pass" and 1 for "possible to pass".
An that algorithm finds its way from x to y (also known example: cat to mouse).
And this exactly is what the following algorithm is doing.</p>
<p>As input we got:</p>
<pre><code>{1, 0, 0,},
{1, 1, 0},
{0, 1, 1} };
</code></pre>
<p>And the output:</p>
<pre><code>(0,0) // ressembles the coordinates of the 1 in top left corner
(1,0) // ressembles the 1 under the first 1 I just explained
(1,1) // ...
(2,1)
(2,2)
</code></pre>
<p>I want change some little things:</p>
<ol>
<li>Change the starting and end position (this algorithm starts in top left and ends in bottom right) - I want mine to start in bottom left and end top right.</li>
<li>This algorithm can only move down and right - I want only move up and right.</li>
</ol>
<p>What changes need to be done, I'm pretty sure but I don't know how to code that:
For 1.) the problem seems to be:</p>
<pre><code>public List<Coordinate> solve() {
return getMazePath(0, 0, new Stack<Coordinate>());
}
</code></pre>
<p>Somehow, I need to do 0-1 with the second zero but how if I haven't access to x and y declaration? I really believe 0-1 would make me start at bottom left instead of top left, is that right?</p>
<p>For 2.) changes for the column, also know as y need to be done.
Instead of +1 it requires -1, is that right?</p>
<p>Sorry for that wall of text, I really tried to keep it short but I seem to have failed :P
Anyway I hope someone will read this^^</p>
<p>Algorithm WITHOUT the changes:</p>
<pre><code>import java.util.Arrays;
import java.util.*;
final class Coordinate {
private final int x;
private final int y;
public Coordinate(int x, int y) {
this.x = x;
this.y = y;

}
public int getY() {
return y;
}
}

throw new NullPointerException("The input maze cannot be null");
}
if (maze.length == 0) {
throw new IllegalArgumentException("The size of maze should be greater than 0");
}
this.maze = maze;
}
public List<Coordinate> solve() {
return getMazePath(0, 0, new Stack<Coordinate>());
}
private List<Coordinate> getMazePath(int row, int col, Stack<Coordinate> stack) {
assert stack != null;
stack.add(new Coordinate(row, col));
if ((row == maze.length - 1) && (col == maze[0].length - 1)) {
Coordinate[] coordinateArray = stack.toArray(new Coordinate[stack.size()]);
return Arrays.asList(coordinateArray);
}
for (int j = col; j < maze[row].length; j++) {
if ((j + 1) < maze[row].length && maze[row][j + 1] == 1) {
return getMazePath(row, j + 1, stack);
}
if ((row + 1) < maze.length && maze[row + 1][col] == 1) {
return getMazePath(row + 1, col, stack);
}
}
return Collections.emptyList();
}

Google script UI - reading to and posting from a spreadsheet, link to populated UI
|
<p>I have created a UI that I would like to use to read from and post to a <a href="https://docs.google.com/spreadsheets/d/11Tf5vD_b_s__F6jPkggE7LUhGH7pQ5Rbuaf_zk2qiWI/edit?usp=sharing" rel="nofollow">spreadsheet</a>. Please ignore, for now, the link formatting in col A. Right now, that's linking to a form. I want to use the UI instead, and will remove references to the linked form as soon as I have this set up.</p>
<p><a href="https://script.google.com/macros/s/AKfycbzsTkgD0KVwIUNhyhqwxeezj5azvTsJSa8ZSmRf9VeMu7vkdvw/exec" rel="nofollow">Here is the current UI</a>.</p>
<p>I would like the end result to be:
1. When a new entry is submitted, managers get emailed with a link.</p>
<ol>
<li><p>That link will open up the UI.</p></li>
<li><p>The top (gray) area will be populated with the pertinent values from the spreadsheet, based on the ID number (column A).</p></li>
<li><p>The bottom area will be blank, or populated with the pertinent values from the spreadsheet if they exist.</p></li>
<li><p>The user will fill out the bottom area as necessary, and submit.</p></li>
<li><p>Data that was entered into the UI will populate the spreadsheet in the correct columns.</p></li>
<li><p>A user looking at the spreadsheet will be able to click on the ID number, and it will pull up the populated UI.</p></li>
</ol>
<p>This is quite simple just using Forms, but I'm looking for something more flexible, so I'm using UI.</p>
<p>Here are my problems:
1. I cannot find a simple, straightforward script that can search for a value, and, once that value is found, get the rest of the data in the row that contains that value.
◦ I've searched like crazy for this, and everyone seems to have a different idea, but none of them fit what I am looking for. </p>
<ol>
<li><p>I understand how to pass values from the UI to the spreadsheet, but not vice-versa.</p></li>
<li><p>Does var formUrl = formResponse.toPrefilledUrl(); work the same way with UI as it does with forms? If not, how do I create a link to the pre-populated UI?</p></li>
</ol>
<p>The code for the UI is below. Yes, I know the UI is ugly right now.</p>

Why does an angular factory interfere with MongoId?
|
<p>I do have a Rails application (Rails 4 / Mongoid) which uses Capybara / Rspec. Furthermore I do use Angular.js for some client stuff. Unfortunately I experience a strange behavior in a spec test.</p>
<pre><code>RuntimeError: Circular dependency detected while autoloading constant Offer
</code></pre>
<p><code>creating_offers_spec.rb</code></p>
<pre><code>require 'spec_helper'
feature 'creating offers' do
before do
visit '/offers/new'
end
scenario 'can create an offer', js: true do
offer_number = Random.rand(10000)
fill_in 'offer_number', with: offer_number
fill_in 'offer_description', with: 'hello world!'
click_button 'btn_submit'
offer_in_db = Offer.where(number: offer_number).first
expect(offer_in_db.description).to eql 'hello world!'
end
end
</code></pre>
<p>As JavaScript driver for Capybara I do use poltergeist.</p>
<p><code>OfferController.js.coffee</code></p>
<pre><code>angular.module('exampleApp').controller 'OffersController', ($scope, Offer) ->
$scope.offer = {}
$scope.offer.positions = []
$scope.addOffer = ->
new Offer().create($scope.offer)
$scope.addPosition = ->
position = { order: $scope.offer.positions.length + 1 }
$scope.offer.positions.push(position)
</code></pre>
<p><code>OfferService.js.coffee</code></p>
<pre><code>angular.module('exampleApp').factory 'Offer', ($resource, $http) ->
class Offer
constructor: ->
@service = $resource('/api/offers/:offersId', {offersId: '@id'}, {update: {method: 'PATCH'}})
defaults = $http.defaults.headers
defaults.patch = defaults.patch || {}
defaults.patch['Content-Type'] = 'application/json'
create: (attrs) ->
offer = new @service(offer: attrs)
offer.$save ($offer) ->
attrs.id = $offer._id
attrs
</code></pre>
<p>Now when I rename the service to OfferService, I don't get the error with the circular dependency. Why does the angular.js service interfere with the mongoid model?</p>
<p>Update: I just figured out that the circular dependency issue does also raise even when I do rename the controller. I forgot to uncomment the <code>Offer.where(...)</code> part of the spec. Why does this happen or let me ask otherwise, any ideas what I could have messed up?</p>
<h2>Update I</h2>
<p>I've added the <code>gem 'capybara-angular'</code> and included it into the <code>spec_helber.rb</code> as described on <a href="https://github.com/wrozka/capybara-angular" rel="nofollow">https://github.com/wrozka/capybara-angular</a>. At least the test do run know. Unfortunately I experience now the problem, that the evaluate_script gets no longer routed to poltergeist because of the above gem.</p>

Adding a UI-Bootstrap Element to DOM inside Directive
|
<p>I am new to angular and I am trying to figure out the following problem. When the user highlights some text, I would like a ui-bootstrap popover to surround the highlighted text. Since this would manipulate the DOM I think I need to use a directive for this. I was able to successfully implement a simpler version of this problem here</p>
<pre><code>app.directive('selectOnClick', function ($window) {
return {
link: function (scope, element) {
element.on('click', function () {
var span = document.createElement("span");
span.style.fontWeight = "bold";
span.style.color = "green";
if (window.getSelection) {
var sel = window.getSelection();
if (sel.rangeCount) {
var range = sel.getRangeAt(0).cloneRange();
range.surroundContents(span);
sel.removeAllRanges();
sel.addRange(range);
}
}
});
}
}
});
</code></pre>
<p>In the above code I am able to surround the highlighted text with a <code>span</code> tag. However I would like to instead use a ui-bootstrap popover. I tried replacing the <code>span</code> part with <code>var popover=angular.element("<a href=#' uib-popover='hello' popover-title='hello'></a>");</code> but this did not work. Am I on the right track or would this approach not work with a ui-bootstrap element?</p>
<p><strong>UPDATED</strong></p>
<p>Here is my attempt at adding the the popover element</p>
<pre><code>app.directive('selectOnClick', function ($window, $compile) {
return {
link: function (scope, element) {
element.on('click', function () {
var popover=angular.element("<a href=#' uib-popover='hello' popover-title='hello'></a>");
if (window.getSelection) {
var sel = window.getSelection();
if (sel.rangeCount) {
var range = sel.getRangeAt(0).cloneRange();
range.surroundContents($compile(popover));
sel.removeAllRanges();
sel.addRange(range);
}
}
});
}
}
});
</code></pre>
<p>Unfortunately I am getting the error <code>TypeError: Failed to execute 'surroundContents' on 'Range': parameter 1 is not of type 'Node'.</code> on the line <code>range.surroundContents($compile(popover));</code> So I suppose <code>$compile(popover)</code> is not the correct type. Can it be converted to <code>Node</code> type somehow?</p>

How do I speed up this multi-statement tabled valued function?
|
<p>I wrote this function that feeds into an XSLT tool for reporting. It's incredibly slow, taking about 1.5-2 seconds on average to return 100 rows. This gets worse as this query can return up to 2000 rows. Any sort of excess load is causing the query to time out, so now I need to optimize it.</p>

<p>Is there anything I can do in the query to optimize this?

Dataset ReadXml returns Rows Instead of Columns
|
<p>I am trying to create a datatable from an xml file, using the dataset readxml method. however i am struggling to define the schema correctly to properly interpret this file.</p>
<p>i think the problem lies with the nesting and the fact that the ColumnUid (which ideally should be the column name) is a value rather than an element.</p>
<p>the datatable it returns at the moment has this structure:[<img src="https://i.stack.imgur.com/ke0rS.png" alt="bad table1" /></p>
<p>and i hope to make it return like this: <a href="https://i.stack.imgur.com/dyen6.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/dyen6.png" alt="good table" /></a></p>
<p>is this possible by defining the correct schema to pass to readxml... or even at all?</p>
<p>I could potentially transpose the datatable after the initial readxml, using eaither linq or a loop but would prefer to avoid this</p>
<p>the xml is as follows (shortened example):</p>
<pre><code> <?xml version="1.0" encoding="utf-16"?>
<DataTable Uid="dtDocRows">
<Rows>
<Row>
<Cells>
<Cell>
<ColumnUid>DocEntry</ColumnUid>
<Value>121496</Value>
</Cell>
<Cell>
<ColumnUid>DocNum</ColumnUid>
<Value>264803</Value>
</Cell>
<Cell>
<ColumnUid>LineNum</ColumnUid>
<Value>0</Value>
</Cell>
<Cell>
<ColumnUid>ItemCode</ColumnUid>
<Value>BENIGRAMST55060075L</Value>
</Cell>
<Cell>
<ColumnUid>Quantity</ColumnUid>
<Value>1.000000</Value>
</Cell>
</Cells>
</Row>
<Row>
<Cells>
<Cell>
<ColumnUid>DocEntry</ColumnUid>
<Value>121658</Value>
</Cell>
<Cell>
<ColumnUid>DocNum</ColumnUid>
<Value>264965</Value>
</Cell>
<Cell>
<ColumnUid>LineNum</ColumnUid>
<Value>0</Value>
</Cell>
<Cell>
<ColumnUid>ItemCode</ColumnUid>
<Value>PYCCHANT202575L</Value>
</Cell>
<Cell>
<ColumnUid>Quantity</ColumnUid>
<Value>1.000000</Value>
</Cell>
</Cells>
</Row>
</code></pre>
<p>and the c# function to return the datatable is this:</p>
<pre><code>private DataTable getDotNetDataTable()
{
DataSet ds = new DataSet();
XDocument xdoc = XDocument.Parse(dtDocRows.SerializeAsXML(SAPbouiCOM.BoDataTableXmlSelect.dxs_DataOnly));
xdoc.Save(@"C:\1\xml\test.xml");
ds.ReadXml(@"C:\1\xml\test.xml");
return ds.Tables.Item(4);
return dt;
}

Create complex object in Python based on property names in dot notation
|
<p>I am trying to create a complex object based on metadata I have. It is an array of attributes which I am iterating and trying to create a dict. For example below is the array:</p>
<pre><code>[
"itemUniqueId",
"itemDescription",
"manufacturerInfo[0].manufacturer.value",
"manufacturerInfo[0].manufacturerPartNumber",
"attributes.noun.value",
"attributes.modifier.value",
"attributes.entityAttributes[0].attributeName",
"attributes.entityAttributes[0].attributeValue",
"attributes.entityAttributes[0].attributeUOM",
"attributes.entityAttributes[1].attributeName",
"attributes.entityAttributes[1].attributeValue",
"attributes.entityAttributes[1].attributeUOM",
]
</code></pre>
<p>This array should give an output as below:</p>
<pre><code>{
"itemUniqueId": "",
"itemDescription": "",
"manufacturerInfo": [
{
"manufacturer": {
"value": ""
},
"manufacturerPartNumber": ""
}
],
"attributes": {
"noun": {
"value": ""
},
"modifier": {
"value": ""
},
"entityAttributes": [
{
"attributeName": "",
"attributeValue": "",
"attributeUOM": ""
},
{
"attributeName": "",
"attributeValue": "",
"attributeUOM": ""
}
]
}
}
</code></pre>
<p>I have written this logic but unable to get the desired output. It should work on both object and array given the metadata.</p>
<pre><code>source_json = [
"itemUniqueId",
"itemDescription",
"manufacturerInfo[0].manufacturer.value",
"manufacturerInfo[0].manufacturerPartNumber",
"attributes.noun.value",
"attributes.modifier.value",
"attributes.entityAttributes[0].attributeName",
"attributes.entityAttributes[0].attributeValue",
"attributes.entityAttributes[0].attributeUOM",
"attributes.entityAttributes[1].attributeName",
"attributes.entityAttributes[1].attributeValue",
"attributes.entityAttributes[1].attributeUOM",
]
for row in source_json:
propertyNames = row.split('.')
temp = ''
parent = {}
parentArr = []
parentObj = {}
# if len(propertyNames) > 1:
arrLength = len(propertyNames)
for i, (current) in enumerate(zip(propertyNames)):
if i == 0:
if '[' in current:
parent[current]=parentArr
else:
parent[current] = parentObj
temp = current
if i > 0 and i < arrLength - 1:
if '[' in current:

How to stop sprite on collision (Keep it from walking on walls)?
|
<p>Thanks to ellertsmari, I am able to get collision detection.
<a href="https://stackoverflow.com/questions/55625639/adding-collision-to-rectangles-so-sprite-wont-go-through">Adding Collision to Rectangles so Sprite Wont Go Through?</a></p>
<p>Just now I want to get my sprite to stop on collision so he won't be walking on walls. </p>
<p>Here's my link to the game:
<a href="https://yewtreedesign.github.io/441_HW/HW11/index.html" rel="nofollow noreferrer">https://yewtreedesign.github.io/441_HW/HW11/index.html</a></p>
<p>Here's the source code that helped me to use sprites.
<a href="https://dev.to/martyhimmel/moving-a-sprite-sheet-character-with-javascript-3adg" rel="nofollow noreferrer">https://dev.to/martyhimmel/moving-a-sprite-sheet-character-with-javascript-3adg</a></p>
<p>so I figure that :</p>
<p><code>positionX + deltaX > 0</code> (checks for left edge collision.)</p>
<p><code>positionX + SCALED_WIDTH + deltaX < canvas.width</code> (checks for right edge collision.)</p>
<p><code>positionY + deltaY > 0</code> (checks for top edge collision.)</p>
<p><code>positionY + SCALED_HEIGHT + deltaY < canvas.height</code> (checks for bottom edge collision.)</p>
<p>I've tried using the guide of how collision is detected on the sprite.
I have accomplished getting the collision detection on the rectangles.</p>
<p>I've tried to add <code>walls.x</code>, <code>walls.y</code>, <code>walls.width</code>, and <code>walls.height</code> within the code where it prevents the sprite from going out of boundaries. My sprite still gets stuck on his starting point. I am not sure what I need to do. I am very new at this. I know instead of <code>canvas.height/canvas.width</code>. I should use <code>walls.height/walls.width</code>for the walls. </p>
<pre><code>

</code></pre>
<p>Everything is showing up as it should. In the console, once you collided with one of the walls, it will show you have collided with wall[i].
Which is great.
I just need help so my sprite won't be walking on walls.</p>
<p>UPDATE:</p>
<p>The sprite does stop when colliding with the wall... Problem is that teleports back to it's begining position...

Tensorflow : Generate freeze graph without having node_names
|
<p>I have some (old) Tensorflow model that have been created by another person.</p>
<p>For each of these model, I want to create frozen graph.</p>
<p>My models can be either <code>Saved Model</code> : </p>
<pre><code>+--- name.txt
+--- saved_model.pb
+--- variables
| +--- variables.data-00000-of-00001
| +--- variables.index
</code></pre>
<p>Or <code>Meta Graphs</code> : </p>
<pre><code>+--- export.data-00000-of-00001
+--- export.index
+--- export.meta
</code></pre>
<p>So, I tried to create frozen graphs using these functions: </p>
<pre><code>import tensorflow as tf
import os
def frozenGraph_SavedGraph(modelFolder, outputFolder, toolsFilepath)
networkGraph = "saved_model.pb"
networkCheckpoint = "variables/variables.data-00000-of-00001"
args = "--checkpoint_version=1\
--input_graph=" + modelFolder + "/" + networkGraph + "\
--input_checkpoint=" + modelFolder + "/" + networkCheckpoint + "\
--output_graph=" + outputFolder + "\
--input_binary=true"
os.system(toolsFilepath + "/freeze_graph.py " + args)
def frozenGraph_Metagraph(modelFolder, outputFolder, toolsFilepath)
networkMeta = "export.meta"
networkCheckpoint = "export.data-00000-of-00001"
args = "--checkpoint_version=1\
--input_meta_graph=" + modelFolder + "/" + networkMeta + "\
--input_checkpoint=" + modelFolder + "/" + networkCheckpoint + "\
--output_graph=" + outputFolder + "\
--input_binary=true"
os.system(toolsFilepath + "/freeze_graph.py " + args)
toolsFilepath = os.path.dirname(tf.__file__) + "/python/tools"
savedGraphFilepath = [PATH/TO/SAVED_GRAPH]
metaGraphFilepath = [PATH/TO/META_GRAPH]
outputFolder = "/output"
frozenGraph_SavedGraph(savedGraphFilepath, outputFolder, toolsFilepath)
frozenGraph_Metagraph(metaGraphFilepath, outputFolder, toolsFilepath)
</code></pre>
<p>But for both of these function, I get the error message : </p>
<pre><code>You need to supply the name of a node to --output_node_names.
</code></pre>
<p>The problem is that I don't think that I have the node names in the file that are available to me (those listed above).</p>
<p>Is there a way to generate frozen graphs without these informations ? (Or a way to retrieve them ?)</p>
<p>EDIT : </p>
<p>I tried to retrieve node names from the graph using this code : </p>
<pre><code>def printNames_Metagraph(modelFolder):
networkMeta = "export.meta"
networkCheckpoint = "export.data-00000-of-00001"
saver = tf.train.import_meta_graph(modelFolder + "/" + networkMeta)
sess = tf.Session()
saver.restore(sess, modelFolder + "/" + networkCheckpoint)
graph = sess.graph
print([node.name for node in graph.as_graph_def().node])
</code></pre>
<p>But it throws a lot of error and warnings : </p>

Swift - Store Dates of Step Counter in Firebase Database
|
<p>I've created a pedometer that stores in a firebase database. However it only stores step data for that one day and when I start another day the steps disappear. I'm guessing I would need to store this data under separate dates to see how many steps were taken each day. I cannot work out how to implement this into my own code. Any help in how to add the date to separate child nodes would be appreciated.</p>

Creating a dequeue method using a Circlular linked Queue in java
|
<p>I'm having trouble figuring out how to finish my dequeue method. I'm only allowed a rear pointer instance variable. I am getting the first two entries delelted from the queue but then it doesn't delete the rest. My code is below. I'm super confused what is going on in my method. Thank you</p>
<pre><code>public class CircularLinkedQueue<T> implements QueueInterface<T>
{
private Node lastNode;
@Override
public void enqueue(Object newEntry)
{
Node newNode = new Node(newEntry, null);
if(lastNode == null)
newNode.setNextNode(newNode);
else
{
newNode.setNextNode(lastNode.getNextNode());
lastNode.setNextNode(newNode);
}
lastNode = newNode;
}
@SuppressWarnings("unchecked")
@Override
public T dequeue()
{
T result = null;
if(!isEmpty())
{
result = (T) lastNode.getNextNode().getData();
lastNode = lastNode.getNextNode();
if(lastNode.getNextNode() == null)
lastNode = null;
else
lastNode.getNextNode().setNextNode(null);
}
return result;
}
@Override
public T getFront()
{
T results = null;
if(!isEmpty())
results = (T) lastNode.getNextNode().getData();
return results;
}
@Override
public boolean isEmpty()
{
if(lastNode == null)
return true;
else return false;
}
@Override
public void clear()
{
lastNode = null;
}
</code></pre>
<p>}</p>
<p>My driver program for the dequeue should be like this.</p>
<pre><code> public static void main(String[] args) {
System.out.println("Create a queue: ");
QueueInterface<String> myQueue = new CircularLinkedQueue<String>();
myQueue.enqueue("Ann");
myQueue.enqueue("Bill");
myQueue.enqueue("Carol");
myQueue.enqueue("David");
myQueue.enqueue("Edgar");
myQueue.enqueue("Fred");
while (!myQueue.isEmpty()) {
Object front = myQueue.getFront();
System.out.println("\t" + front + " is at the front of the queue.");
front = myQueue.dequeue();
System.out.println("\t" + front + " is removed from the front of the queue.");
}
}
}
</code></pre>
<p>Output should look like this</p>
<pre><code>Ann is at the front of the queue.
Ann is removed from the front of the queue.
Bill is at the front of the queue.
Bill is removed from the front of the queue.
Carol is at the front of the queue.
Carol is removed from the front of the queue.
David is at the front of the queue.
David is removed from the front of the queue.
Edgar is at the front of the queue.
Edgar is removed from the front of the queue.
Fred is at the front of the queue.
Fred is removed from the front of the queue.
</code></pre>
<p>My output looks like this</p>
<pre><code>Ann is removed from the front of the queue.
Bill is at the front of the queue.
Bill is removed from the front of the queue.

Multipart data sending got 408 Status
|
<p>guys. Need help with sending POST request with multipart-data.</p>
<p>I have a method to create request on my client side. Here it is:</p>
<pre><code>public void sendMultipart(String cmd , Employee emp) {
CloseableHttpClient httpClient = HttpClients.createDefault();
HttpPost uploadFile = new HttpPost(baseUrl + cmd);
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
FileBody f = new FileBody(emp.getPhoto());
try {
StringBody s = new StringBody(emp.getLogin());
builder.addPart("name", s);
builder.addPart("file", f);
} catch (UnsupportedEncodingException ex) {
Logger.getLogger(RestTemplateRequester.class.getName()).log(Level.SEVERE, null, ex);
}
uploadFile.setHeader("Accept", "application/json");
uploadFile.setHeader("Content-type", "application/json");
uploadFile.setHeader("enctype","multipart/form-data");
uploadFile.setHeader("accept-charset","UTF-8");
//builder.addTextBody("field1", "yes", ContentType.TEXT_PLAIN);
//builder.addBinaryBody(emp.getLogin(), emp.getPhoto(), ContentType.MULTIPART_FORM_DATA, "file");
HttpEntity multipart = builder.build();
uploadFile.setEntity(multipart);
try {
HttpResponse httpResponse = httpClient.execute(uploadFile);
int status = httpResponse.getStatusLine().getStatusCode();
String str = httpResponse.getStatusLine().getReasonPhrase();
} catch (IOException ex) {
Logger.getLogger(RestTemplateRequester.class.getName()).log(Level.SEVERE, null, ex);
}
}
</code></pre>
<p>Also I have a method to handle request on my server side:</p>
<pre><code>@RequestMapping(value = "photo", consumes = "multipart/form-data")
public @ResponseBody
void uploadFileHandler(@RequestParam("name") String name,
@RequestParam("file") MultipartFile file) {
if (!file.isEmpty()) {
try {
byte[] bytes = file.getBytes();
// Create the file on server
File serverFile = new File(name);
BufferedOutputStream stream = new BufferedOutputStream(
new FileOutputStream(serverFile));
stream.write(bytes);
stream.close();
} catch (Exception e) {
e.getMessage();
}
}
}
</code></pre>
<p>And in my context:</p>
<pre><code><bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- setting maximum upload size -->
<property name="maxUploadSize" value="100000" />
</bean>
</code></pre>
<p>The problem which I have now - is a 408 error "Request Time Out".
My common aim is - send JSON with file to server. I so green with web services in java, so i got some troubles.
Please, It will be great, if someone can give me a little advice. Thank you.</p>

PHP how to reuse a function from a clean state
|
<p>`I have a function called lets say calculate; what i want to do is run some loops with in the function calculating an outcome. at times this function does fail as it will get stuck in a loop, so iv got it covered to exit the loop but my problem is i want to restart this function and hope it come out with an outcome if not i will try again... on average the request does not have an outcome around 1 in 20, i need to restart the function from a clean slate.</p>
<p>i have tried to unset all the vars before i rerun the process with out success.please note this function will fail at times from the information handed to the process, un avoidable so
when this accurs i just want to rerun the function automatically to generate an outcome.</p>
<p><a href="http://www.gamezslave.com/test/DynamicSlots.swf" rel="nofollow">http://www.gamezslave.com/test/DynamicSlots.swf</a> this is my test prototype give you an idea
sometimes you refresh it will error because of this factor.</p>
<pre><code><?php
$checker = 0; // if i cant get a result i could use this will tick up until condition
function shuffleArray($myArray) {
$value_count = array_count_values($myArray);
$last_value = $myArray[count($myArray) - 1];
unset($myArray[count($myArray) - 1]);
$shuffle = array();
$last = false;
while (count($myArray) > 0) {
$keys = array_keys($myArray);
$i = round(rand(0, count($keys) - 1));
while ($last === $myArray[$keys[$i]] ) {
$i = round(rand(0, count($keys) - 1));
echo "stuck";
$checker++;
if($checker>10){
echo " Too many checks so die, and restart process ";
return false;
bob; // this is the check function to goto and restart
}
}
$shuffle[] = $myArray[$keys[$i]];
$last = $myArray[$keys[$i]];
unset($myArray[$keys[$i]]);
}
if ($last_value === $last) {
$i = 0;
foreach($shuffle as $key=>$value) {
if ($value !== $last_value) {
$i = $key;
break;
}
}
array_slice($shuffle, $i + 1, 0, $last_value);
} else {
$shuffle[] = $last_value;
}
return $shuffle;
}
print_r(shuffleArray(array(1,5,5,3,7,7,7,7))); // just a example
function bob(){
if($checker>10){
$checker = 0;
shuffleArray();
echo "bob";
reset($myArray); // thought this may clean/reset the array i couldnt use
}
}
</code></pre>
<p>The idea this shuffle returns that no two symbols elemts of the same will be next to each other but sometimes at the end of the array as its shuffling randomly im left with bad odds (apple, orange, orange, orange) so what i need to do is resart this process again from start take in mind there is about 10 different item in the array and duplicates of each for example 10 apples ,10 oranges 4 bannanas 3 grapes sometimes the shuffle manages to generate an outcome where im stuck with too many of the same item at the end of the array wich then i need to rerun the script(and this bit is the problem) i dont know how.</p>
