session method cannot be called 2 times in controller | <p>In the code below, when the #call method executes, it redirects the call to the #connect method to play an audio, then the #connect method redirects to #menu_selection where everything breaks. the error I get in heroku logs is that sessions is nil or defined. </p>
<p>What I dont understand is that I am already using session[:user_id] in the first method #call. why is it no defined in the #menu_selection method?</p>

<p>In the #menu_selection method I get the error : undefined local variable or method `session'</p>
<p>Its in the first line where I'm defining the "list" variable.</p>
<p>I never had this kind of issue before. If anyone knows whats going on, I would appreciate your help.</p>
<p>I tried defining the first @list variable as a class variable outside of the method #call but It gives me the same error that I get now. I also tried making it a class variable inside the #call method to try using it in #menu_selection method, but I get an "@@list is undefined" error.</p> | 3 |
Submit hidden fields with listbox items that have been moved using jQuery | <p>I have two list boxes that I can move items to and from using jQuery. A summary of the code follows:</p>
<pre><code><select multiple size="10" id="from">...</select>
<select multiple id="to" size="10" name="subitted array[]">...</select>
</code></pre>
<p>Some buttons that when clicked move the items from the above list boxes:</p>
<pre><code><a href="javascript:moveSelected('from', 'to')">&gt;</a>...
<a href="javascript:moveSelected('to', 'from')">&lt;</a>
<a href="javascript:moveAll('to', 'from')" href="#">&lt;&lt;</a>
</code></pre>
<p>The jQuery functions:</p>
<pre><code>function moveAll(from, to) {
$('#'+from+' option').remove().appendTo('#'+to);
}
function moveSelected(from, to) {
$('#'+from+' option:selected').remove().appendTo('#'+to);
}
</code></pre>
<p>I also have the following function that I call on submit:</p>
<pre><code><form name="selection" method="post" onSubmit="return selectAll()">... </form>
function selectAll() {
$("select option").attr("selected","selected");
}
</code></pre>
<p>But this only returns by POST the values in the right list box. I would also like to submit other fields present in the form (e.g. hidden fields). How can I do this?</p>
<p>Many thanks. </p> | 3 |
Missing tick label from a plot of data indexed with a PeriodIndex | <p>I'm trying to plot two series and have the x-axis ticks labeled every 5 years. If I index the data with a <code>PeriodIndex</code> for some reason I get ticks every 10 years. If I use a list of integers to index, then it works fine. Is there a way to get the right tick labels with a <code>PeriodIndex</code>?</p>
<pre><code>import pandas as pd
import numpy as np
import matplotlib as mpl
import matplotlib.pyplot as plt
np.random.seed(0)
idx = pd.PeriodIndex(range(2000,2021),freq='A')
data = pd.DataFrame(np.random.normal(size=(len(idx),2)),index=idx)
fig,ax = plt.subplots(1,2,figsize=(10,5))
data.loc[:,0].plot(ax=ax[0])
data.iloc[9:,1].plot(ax=ax[1])
ax[1].xaxis.set_major_locator(mpl.ticker.MultipleLocator(5))
plt.show()
</code></pre>
<p><a href="https://i.stack.imgur.com/7SPHj.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7SPHj.png" alt="with PeriodIndex"></a></p>
<pre><code>idx = range(2000,2021)
</code></pre>
<p><a href="https://i.stack.imgur.com/be65y.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/be65y.png" alt="with integer idex"></a></p>
<p>The workaround I know is to convert the <code>PeriodIndex</code> to <code>DatetimeIndex</code> and then to an array of <code>datetime.datetime</code>objects and use <code>plt.plot_date()</code> to plot and <code>mpl.dates.YearLocator(5)</code> to format. This seems overly complicated.</p> | 3 |
OAuth2 Single-sign-on component, force reauthentication | <p>Right now I have a Abstract Adapter that handles all the different social medias, the social media adapters just hold the information and pass that to the abstract adapter that then uses OAuth2 to authenticate the user and allows API calls to be made. I want to FORCE the user to reauthenticate everytime they try to login, link or unlink an account. How do I tell OAuth2 I want them to reauth everytime? This is what I pass right now for the authentication:</p>
<pre><code>$this->_oauth = new \League\OAuth2\Client\Provider\GenericProvider(array(
'clientId' => $this->_key,
'clientSecret' => $this->_secret,
'redirectUri' => $this->getObject('request')->getBaseUrl() . $this->_redirect_uri,
'urlAuthorize' => $this->_authorize_uri,
'urlAccessToken' => $this->_access_uri,
'urlResourceOwnerDetails' => ''
));
</code></pre>
<p>So my question, everything works fine, linking, unlinking and signing into an account which has been linked with a social media using that social media. But how do I force the user to reauth everytime even if they logged into Facebook 5 minutes ago and Facebook knows it still has a active session? (Same thing for all other social medias, Facebook is just an example)</p> | 3 |

AS3 Does Loader ProgressEvent.PROGRESS event guarantee that server received the request? | <p>I am new to Action Script and I've faced the following code:</p>
<pre><code>var lc: LoaderContext = new LoaderContext();

lc.allowCodeImport = false;
var ldr: Loader = new Loader();
ldr.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loadHandler);
ldr.load(new URLRequest(url), lc);

<p>Does <code>ProgressEvent.PROGRESS</code> event guarantee that server received the request? Can I asume in <code>loadHandler</code> that request has been received or should I use </p>
<pre><code>ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, loadHandler);
</code></pre>

How to render series data to a title in sencha charts | <p>I have a chart retrieving data from my store, the four bits of information are the following</p>
<p>Model Code</p>
<pre><code>Ext.define('QvidiApp.model.ClipsViews', {

<p>Now I have the viewed field and the glances field as the numeric fields in the chart, and the title field as the category title in the chart.</p>
<p>I want to render the title name of the field when I hover over it, reason id this. The titles are too long to fit in the x-axis of the chart so in place of the titles I am putting 'meta_id'. So when I hover over the x-axis meta_id field I want the title name to be shown</p>
<p>so for example</p>
<p>meta_id 100 will equal title value ###</p>
<p>Here's is my chart code so far</p>

Colour polygons of a map in R? | <p>I have used Raster package to upload the map of Spain by provinces (level 2) and I'd like to fill them with colours according to theincome per capita.
Here there's the file with the income per share and the number assigned to each province. Notice that ID_2 is the number assigned by the package Raster, and the variable PROV is the official number assigned by the Spanish Government. </p>
<pre><code>library(raster)
esp<-getData('GADM', country="ESP", level=2)
espPols <- unionSpatialPolygons(esp, esp$ID_2)
renta <- read.table("renta.csv",sep = ";", header=TRUE)
espMapRenta <- SpatialPolygonsDataFrame(espPols, renta)
plot(espMapRenta)
</code></pre>
<p>The first problem I encounter is that there are some provinces repeated in the package, and the second one is that I don't know how to fill each province in a gradient colour by the level of income.</p>
<p>Thank you very much for your help!!
PS. The link to the income per capita data is here: <a href="https://www.dropbox.com/s/si6zpv7p2nap9zg/renta.csv?dl=0" rel="nofollow">https://www.dropbox.com/s/si6zpv7p2nap9zg/renta.csv?dl=0</a></p> | 3 |

Can't render simple transparent sprites in SharpGL | <p>I know how to generate a plane and map a texture. Now, I am trying to display an alpha-blended PNG on my form, like it was a sprite.</p>

// Get one texture id, and stick it into the textures array.
gl.GenTextures(1, textures);
// Bind the texture.
gl.BindTexture(OpenGL.GL_TEXTURE_2D, textures[0]);
gl.Enable(OpenGL.GL_BLEND);
gl.BlendFunc(OpenGL.GL_SRC_ALPHA, OpenGL.GL_DST_ALPHA);
var locked = textureImage.LockBits(
new Rectangle(0, 0, textureImage.Width, textureImage.Height),

How to route posts from firebase to its own section in polymer? | <p>im struggling with some issues regarding routing blog posts from firebase, which i previously pushed it using paper-input and firebase-elements.
this is my code of the custom element:</p>

Displaying remote images in a firefox add-on panel | <p>I'm trying to display remote images in a FireFox add-on panel, but the <code>src</code> attributes are being converted from something like this:</p>
<p><code>http://example.com/image.jpg</code></p>
<p>to something like this:</p>
<p><code>resource://addon_name/data/%22http://example.com/image.jpg%22</code></p>
<p>I can't figure out if I'm breaking a security policy or not. </p>
<p>In my add-on script (index.js) I'm retrieving image URLs using the sdk/request API and passing them to my content script (data/my-panel.js). My data/my-panel.js file is creating DOM elements in my panel file (data/popup.html) – including images – using the URLs passed from index.js. Here are the relevant bits of code:</p>
<p><code>index.js</code></p>

var panel = require("sdk/panel").Panel({
width: 500,
height: 500,

Request({
url: url,
onComplete: function(response) {
// Get the JSON data.
json = response.json;
// Launch the popup/panel.
panel.show();
panel.port.emit("sendJSON", json);

var node = document.createElement("li"); // Create a <li> node

imgTag.setAttribute('src', img);
imgTag.setAttribute('alt', desc);
imgTag.style.width= '25px';
titleTextNode = document.createTextNode(title);
descTextNode = document.createTextNode(desc);
node.appendChild(titleTextNode); // Append the text to <li>
node.appendChild(descTextNode); // Append the text to <li>
document.getElementById("myList").appendChild(node); // Append <li> to <ul> with id="myList"
document.getElementById("myImgs").appendChild(imgTag);
});
});

<html>
<head>
</head>
<body>
<ul id="myList"></ul>

How to set a custom message in the return path? | <p>I'm sending automated emails using java mail to my colleagues in different states (all within our company). I set the <code>return path</code> as their manager's emails. In case the recipient's mail box is full, their manager would get an <code>undeliverable email</code> notification. </p>
<p>Is there any way I can customize that <code>undeliverable message</code>, so that their managers who receive the <code>undeliverable notification</code>, would also get instructions on how to handle those emails and "couch their subordinates" ? </p>
<p>I couldn't find any documentation on this. Is this even possible ? </p> | 3 |

Quartz .net: with a JobListener, Jobs are not triggered | <p>I have properly created and scheduled a Job (I don't write the Job and Trigger creation here, just to be brief). Scheduler is created and started as follows:</p>
<pre><code>_scheduler = New StdSchedulerFactory().GetScheduler
_scheduler.Start()

<p>Jobs are executed at the scheduled time.</p>
<p>Then I created a very simple (and empty, at the moment) a JobListener:</p>
<pre><code>Imports Quartz
Public Class JobListener
Implements IJobListener
#Region "Public properties"
Public ReadOnly Property Name As String Implements Quartz.IJobListener.Name
Get
Return "JOB_LISTENER"
End Get
End Property
#End Region
#Region "Methods"
Public Sub JobExecutionVetoed(context As Quartz.IJobExecutionContext) Implements Quartz.IJobListener.JobExecutionVetoed
Throw New NotImplementedException
End Sub
Public Sub JobToBeExecuted(context As Quartz.IJobExecutionContext) Implements Quartz.IJobListener.JobToBeExecuted
Throw New NotImplementedException
End Sub
Public Sub JobWasExecuted(context As Quartz.IJobExecutionContext, jobException As Quartz.JobExecutionException) Implements Quartz.IJobListener.JobWasExecuted
End Sub
#End Region
End Class

KafkaException error when using MessageHub Service | <p>Using the Message Hub service recently, I have discovered that previously working apps have begun failing with a <code>KafkaException</code> or <code>Failed to update metadata</code>. </p>

Do batch scripts treat variables differently in blocks? | <p>I'm running a batch file which updates some variables, notably %PATH%. My environment has a known bug where on of the directories in %PATH% is quoted, i.e.</p>
<pre><code>PATH=c:\windows;...;"c:\program files\foo"\bin;c:\program files\...
</code></pre>
<p>I have a script which appends to PATH. When I do it inside an <code>IF</code> block, I get an error, e.g:</p>
<pre><code>IF "1"=="1" (
SET "PATH=%PATH%;c:\foo"
)
</code></pre>
<p>Gives the error</p>
<blockquote>
<p>\Microsoft was unexpected at this time.</p>
</blockquote>
<p>Where <code>\Microsoft</code> is obviously a fragment from one of the directories in %PATH%.</p>
<p>I don't get the error if the SET is not within a conditional block. Why is this?</p>
<p>Edit: It seems that this has more to do with the fact that PATH also contains parenthesis. Here's a better example of the issue:</p>
<pre><code>C:\temp>SET "FOO=C:\Program Files (x86)\;foo"
C:\temp>ECHO %FOO%
C:\Program Files (x86)\;foo
C:\temp>IF "1"=="1" ( ECHO %FOO% )
\ was unexpected at this time.
C:\temp>IF "1"=="1" ECHO %FOO%
C:\Program Files (x86)\;foo
</code></pre>
<p>So my question is really, why does it break if it's in the paren-delimited block?</p> | 3 |

C# Issue sourcing image size - WPF | <p>I am attempting to fit multiple images within the bounds of my screen. I am utilizing a stack panel seeing that this is the best layout for my end goal.
Images from the users local machine should be opened and added to the stack pannel until there is no more screen space to work with.</p>
<p>The issue i am running in to is, when i load my bitmap into memory it is providing me with an inaccurate width (its providing the DPI width however i desire the final width it holds on the screen). ideally, if your screens width is 1000 I would want to load images until 1000 or near 1000 width has been used on screen which is difficult if i cannot source the width of the image (similar to what windows would give me for the width if i looked at the file in explorer)</p>
<p>I am using the following to load the bitmap into memory:</p>
<pre><code> BitmapImage bitmap = new BitmapImage();
bitmap.BeginInit();
bitmap.UriSource = new Uri(fullFilePath, UriKind.Absolute);
bitmap.EndInit();
MessageBox.Show(bitmap.Height.ToString() + "is the height. this is the width->" + bitmap.Width.ToString());
</code></pre>
<p>The Results i am getting are:
1728 is the height<br>
1152 is the width</p>
<p>for an image which is actually 864 x 1296 (a jpg image).</p>
<p>These images are in a stack pannel, would it be possible to extract the size of a specific stack pannel child?
Example <code>stackpannel.children[0].width</code> Something to that effect?</p> | 3 |

python original dictionary being modified after each iteration | <p>I have tried to implement Karger's algorithm to compute min cut of a graph by python, and tested my code with a small input graph.

Disabling the iframe overflow:auto; on a Google Apps Script Web App | <p>When creating an apps script web app, I constantly have a vertical scroll bar on the right hand side that is not representative of the pages size and doe snot move when scrolling.</p>
<p>The web app runs inside an iframe, which had an id of <code>userHtmlFrame</code> with <code>overflow-y: scroll;</code> set on it. This causes a scrollbar to always be present whether the page needs to scroll or not. If the page doesn't need to scroll, then it hides content on the right side as seen here: <a href="https://i.stack.imgur.com/fRhtK.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/fRhtK.png" alt="enter image description here"></a></p>
<p>If the page does need to scroll, it will hide the scrollbar that is supposed to be there.</p>
<p>If I add the appropriate CSS, it does not work. It looks like I cannot change the styling on the iframe from within it.</p>
<p>Is there a way to change the styling on the iframe, or some other property when generating the HTML in apps script to disable the scrolling?</p> | 3 |

DFP sizeMapping Breaks Sponsorships | <p>In my experiences so far, sizeMapping(), for responsive ads in DFP breaks sponsorships. </p>
<p>For example, if I define a sizeMapping like so:</p>
<pre><code>addSize([1024, 768], [970, 90], [728, 90], [320, 50], [300, 250])
</code></pre>
<p>Then I setup a sponsorship on a particular ad unit that's a 728x90.
I also setup a Run of Site (placement) 970x90 that includes all ad units, including the sponsored one, at a lower priority.</p>
<p>The result is that the 970x90 will show before the sponsored 728x90 because of the sizeMapping variable, even on the ad units that are specifically sponsored by the 728x90. </p>

<p>theoretically if I set the elevation of the LinearLayout equal to the app bar(4dp or 8dp or whatever), they should be able to bridge the step themselves, but no. Even if I set the elevation of the LinearLayout to 20, it still appears to be underneath the app bar.</p>
<p>Is there any way to tackle this?</p> | 3 |
How to gracefully handle nil checking, with optional paramter values? | <p>I have the following code:</p>
<pre><code>@IBAction func search(sender: AnyObject) {
let searchWord = searchQ.text
let r = searchRadius.text
let latitude = searchLat.text
let longitude = searchLon.text
customSearch(searchWord!, radius: r!, lat: latitude!, lon: longitude!)
}
</code></pre>
<p>the method <code>customSearch</code> has default parameters set in case the user doesn't put anything in, so...</p>
<p>how can I CHECK if searchWord, r, latitude and longitude are nil. If they are nil, then use customSearch functions default parameters, otherwise, use whichever ones were provided and fill out the rest with default values?</p>
<p>Oh and to elaborate, apparently if I take the value of a textfield, and it's empty, it's not nil but an empty string.. so I added the following:</p>
<pre><code>func customSearch(q:String = "", radius:String = "25", lat:String = "33.960", lon:String = "-118.4179") {
let geoSearchWord = (q == "" ? q : "geoSearchWord=\(q)")
let geoSearchLat = (lat == "" ? "33.960" : "&geoSearchWordLat=\(lat)")
let geoSearchLon = (lon == "" ? "-118.4179" : "&geoSearchWordLon=\(lon)")
let geoSearchRadius = (radius == "" ? "25" : "&geoSearchWordRadius=\(radius)")
let twitterURLRequest: String = "https://quiet-cove-5048.herokuapp.com/tw?\(geoSearchWord)\(geoSearchLat)\(geoSearchLon)\(geoSearchRadius)"
alamoRequest(twitterURLRequest)
}
</code></pre>
<p>but I'm still not happy with it.</p> | 3 |
Select value from range based on match | <p>I've got the following set of data and have setup a another table to the right which holds the cost of each location.</p>
<p><a href="https://i.stack.imgur.com/1p12K.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/1p12K.png" alt="dataset"></a></p>
<p>The cost column currently I've got <code>=IF(EXACT(B2,"Home"),D2*17.2,D2*0.09)</code>, however the cost per kWh can change based on different locations. I want to be able to lookup the cost based on another table which will make things more manageable.</p>

SQLite3 issue with getting row ID | <p>it's the first time I am using Sql database and in a quick search I have reached a video explaining how to add an external file called "2SwiftData" , it has many func such as "createTable" etc. now a few Q: <br>
1) am I supposed to close and open the DataBase? <br>
2) why cant I find the table I created in spotlight search? <br>
3) one of the func is <code>SD.lastInsertedRowId()</code> which should return the ID of the row yet no matter what I do, 0 is returned , and the table has info row in<br></p>
<p>The function:</p>
<pre><code>public static func lastInsertedRowID() -> (rowID: Int, error: Int?) {
var result = 0
var error: Int? = nil
let task: ()->Void = {
if let err = SQLiteDB.sharedInstance.open() {
error = err
return
}
result = SQLiteDB.sharedInstance.lastInsertedRowID()
SQLiteDB.sharedInstance.close()
}
putOnThread(task)
return (result, error)
}
</code></pre>
<p>The request:</p>
<pre><code> let ra = SD.lastInsertedRowID() <br>
print(ra)

How do I chart the a second custom data point in Dygraphs? | <p>I'm toying around with Dygraphs and really liking it. However I'm having trouble setting a string value for the second point. I've tried to produce it to be a date, but I would rather keep the custom format for my own date and time.</p>
<p>My simple chart is </p>
<pre><code>new Dygraph(document.getElementById("graphdiv"),
dataload
,
{
labels: [ "x", "A" ],
title: 'Point',
ylabel: 'Value in Eng Units',
xlabel: 'Time & Date'
});
</code></pre>
<p>The code that provides the data into dataload is </p>
<pre><code>i = 0
while ( i < 100){
datappointvalue = [ archivetime[i], archivevalue[i] ] ;
dataload.push(datapidvalue);
}
</code></pre>
<p>As you can guess archivetime and archivevalue are arrays that I populate.
archivetime has the format of a string "22-MAR-2016 20:20:41.26" archivevalue has the format of decimal/int "144.32".</p>
<p>My graph always comes out like
<a href="http://i.stack.imgur.com/XrcZ7.png" rel="nofollow">this</a> - It will always get the values of archivevalue, but never archivetime.</p>
<p>So the question is ultimately how can I display my second value to be the date and time. I would prefer not having to reformat my archivedate into something else, but if necessary that can be done.</p>
<p>Thanks!</p> | 3 |

Miniflux API URL endpoint | <p>I have <a href="http://miniflux.net" rel="nofollow">Miniflux</a> running on an Amazon EC2 instance which I intend to use for my Android application. According to the Miniflux documentation <a href="https://miniflux.net/documentation/json-rpc-api#example-curl" rel="nofollow">here</a> I should be able to get a JSON response with this URL endpoint: </p>
<pre><code>www.mydomain/miniflux/jsonrpc.php

"id":null,
"error":{
"code":-32700,
"message":"Parse error"

</code></pre>
<p>To get more information in JSON format I need to pass in more arguments but the Miniflux documentation does not explain how. The OpenWeatherMap API on the other hand, has a <a href="http://openweathermap.org/appid" rel="nofollow">guide</a> on how the URL endpoint may be used with the API key.

Microsoft.Owin.Host.HttpListener isn't being copied to a referencing projects' build output | <p>I am referencing a one project in Visual Studio solution from another project in the same solution. The project being referenced (Project B) has Microsoft.Owin.Host.HttpListener nuget package and so the .dll referenced in it. The project that is referencing project B (Project A) is being built. The output folder gets all those dlls referenced in Project B, except Microsoft.Owin.Host.HttpListener.dll even though it is marked as Copy Local - true.</p>
<p>The Microsoft.Owin.Host.HttpListener.dll is the only one that I've faced so far that refuses to be copied to the Project A's build output as a part of MSBuild's _CopyFilesMarkedCopyLocal step regardless of the settings.</p>
<p>I've tried to add it to a entries in app.config, it didn't help. </p>
<p>I've arranged the sample project showcasing the referencing problem and uploaded it to GitHub <a href="https://github.com/maxpavlov/HttpListenerTest" rel="nofollow noreferrer">here</a>.</p>
<p>You are free to play with the settings. </p>
<p>I've check out the related questions in Stackoverflow before asking this and they are not answered or unrelated.</p>
<p>Please give me a hint how to get the .HttpListener.dll to be copied along with other .dlls to a referencing projects output as expected.</p> | 3 |

Azure Api Service and Individual accounts | <p>I've originally used Web API 2 with Individual Accounts so that users can create a new account by supplying a username/email and password which is stored in my DB.</p>
<p>I'm now looking to put this API into Azure API service and have looked at the documentation about <a href="https://azure.microsoft.com/en-gb/documentation/articles/app-service-api-dotnet-service-principal-auth/" rel="nofollow">authentication </a> but this mostly talks about external authentication. Can we use Individual Accounts with Azure API or will I need to handle this myself within the actual API?</p>
<p>Also, with the third party authentication all the examples use a redirected website (FaceBook, Google) to get the user to log in. I want to call this from a mobile app so does it support extenal authentication using API calls or will I have to do that myself?</p>

Can characters be used as indices? | <p>Let's define, for example, </p>
<pre><code>x = 10:10:2000;
</code></pre>
<p>As is well known, integer values can be used as indices:</p>
<pre><code>>> x(9)
ans =
90
</code></pre>
<p>In Matlab, characters can often be used where a number would be expected, with Matlab doing the conversion automatically. For example, since the ASCII code of <code>'a'</code> is <code>97</code>,</p>
<pre><code>>> 'a'+1
ans =
98
</code></pre>
<p>Can characters be also used as indices? Does Matlab convert them into integers?</p> | 3 |

Serialising string arrays into json | <p>So, I've been tinkering with go and have a small problem. I have something that needs to be serialised into a json like so. </p>
<pre><code>{
"name" : "Steel",
"things" : ["Iron", "Carbon"]
}
</code></pre>
<p>The struct to hold this looks like this. </p>
<pre><code>type Message struct {
name string
things []string
}
</code></pre>
<p>and my code itself like this</p>
<pre><code>func main() {
i := Message{"Steel", []string{"Iron", "Carbon"}}
fmt.Println(i);
b, _ := json.Marshal(i)
fmt.Printf(" Json %v\n", b);
var o Message;
json.Unmarshal(b, &o)
fmt.Printf(" Decoded %v\n", o);
}
</code></pre>
<p>When I deserialise the data though, I get back an empty <code>Message</code> like so</p>
<pre><code>{Steel [Iron Carbon]}
Json [123 125]
Decoded { []}
</code></pre>

How to start and stop video recorder from android application | <p>I need to launch video recorder on click of the button from my application.When user start the recording I need to show count down timer and when the time elapsed video recorder should close automatically.</p>
<p>I searched on many forums and got suggestions to use custom camera recorder, but I don't want use it as I will loose native features like flash,front camera etc.</p>
<p>So the idea is to launch the native video recorder and show timer and when time expires close the recorder and come back to application.</p>
<p>I am able to launch the recorder by 'startActivity()' with camera intent but not able to set timer and close the recorder. Please let me know if it is poosible to do it.</p>

@Override
public void onClick(View view) {
// Launch an intent to capture video from MediaStore
Intent takeVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
startActivityForResult(takeVideoIntent, ACTION_TAKE_VIDEO);

Translation and fixed number of letters words | <p>In a part of my software I need, in different languages, lists of words having a fixed number of letters.</p>
<p>My software is already internationalized (using <code>gettext</code>, and it works fine). But, as it's not possible to translate a 4 letters word from english into a 4 letters word in another language (apart from some exceptions maybe), I can't imagine a reasonable way of letting <code>gettext</code> deal with these words lists.</p>
<p>So, for now, I decided to store my words like this (shortened example with english and french names):</p>
<pre><code>FOUR_LETTERS_WORDS = { 'fr': ["ANGE", "ANIS", "ASIE", "AUBE", "AVEN", "AZUR"],
'en': ["LEFT", "LAMP", "ATOM", "GIRL", "PLUM", "NAVY", "GIFT", "DARK"] }
</code></pre>
<p>(This is python syntax, but the problem has not much to do with the programming language used)</p>
<p>The lists do not need to have the same length; they do not need to contain the same words.</p>
<p>My problem is following: if my software is to be translated in another language, like say, german, then all the strings that fall within the scope of <code>gettext</code> will be listed in the pot file and will be available for translation. But then, I also need a list of 4 letters words in german, that won't show up in the translation file.</p>
<p>I would like to know whether I need to think to ask the translator if he/she can also provide a list of such words, or if there's a better way to deal with this situation? (maybe finding a satisfying workaround with <code>gettext</code>?).</p>
<p>EDIT Realized the question has actually not much to do with the programming language, so removed the python* tags</p> | 3 |

android browser does not launch app | <p>I am unable to get the app I have written to launch when a certain url is passed back to the browser.</p>
<p>When the user launches the default browser and goes to the where my server is running for example: www.test.com, a list of films and books are displayed on the remote server. When the user selects one of these items i.e. a film or book - the server sends back a url that starts with bb:// and contains the uri link.fil?data=1. So the url looks like this when sent back from the server:</p>
<pre><code> bb://link.fil?data=1
</code></pre>
<p>Currently I have the manifest which declares the following filter intent:</p>

<category android:name="android.intent.category.BROWSABLE" />
<data
android:scheme="bb"
android:host="test.com"
android:path="/.*"
android:pathPattern="/.*\\.*"/>
/>
<data

<p>What I am trying to make happen is when the user selects a book of film the returning url launches my app. </p>

Why does retain cycle leak memory? | <p>I'm a little confused about retain cycle.As the pictures show,it's a retain cycle.My opinion is when running out of the scope,test0 will release,obj_ will release,so the reference count of object A and B will be one, also when this happens on test1,then the reference count will be zero,finally,free the memory.What's the problem?

Insert "cut off" field in R surface plot | <p>I'm using persp() to create a 3d plot (but I'm open to anything that will get the job done). Now I want to add a 2d field to make it clear where the 3d plot is above a specific Z value. Is there a way to achieve this? Ideally it would ideally be something like a semi transparent surface where you can see the mass under the surface vs over. </p>
<p>Using the example from the persp documentation</p>
<pre><code>f <- function(x, y) { r <- sqrt(x^2+y^2); 10 * sin(r)/r }
x <- seq(-10, 10, length= 30)
y <- x
z <- outer(x, y, f)
z[is.na(z)] <- 1
persp(x, y, z, theta = 30, phi = 30, expand = 0.5, col = "lightblue",
ltheta = 120, shade = 0.75, ticktype = "detailed",
xlab = "X", ylab = "Y", zlab = "Sinc( r )"

Angular2 w/ Typescript - Client/Server App the right way? | <p>I'm cutting my teeth on Angular2 (and Angular in general) getting the core concepts under my belt and have been working on my first "real" application. I'm using some sample projects on GitHub and the quickstart on the Angular site as guides but have run into some roadblocks and am looking for some advice on the "right" way to set up the directory structure, integrate typings and reference node modules in the application. Obviously some aspects would be personal coding preference so I'm just out here fishing for some best practices advice.</p>
<p>Application Overview:</p>
<ul>
<li>Application has a server-side component used to connect to a local SQL server and brokers calls from the client side to provide data to be displayed.</li>
<li>Application has a client-side component used to serve pages/template and communicate with the server-side to make calls to retrieve data and display it on the page</li>
<li>Application uses gulp to configure and launch both the server and the client side (different calls - eg: gulp start-server / gulp start-client)</li>
</ul>
<p>I have the basics of all of the working so my question isn't really about that. My issues come up when I have node modules that I need to leverage and what is the right way / best way to integrate those.</p>
<p>Lets say my basic directory structure is like this (based on sample projects I'm using as references)...</p>
<pre><code>- client
|- public
|- app
|- css
|- lib (some js files)
|- etc...
index.html
|- typings
client.ts/js
- node_modules
|- modules installed via npm install
- server
|- core (contains db-connection)
|- typings
server.ts/js
</code></pre>
<p>Now, lets say I needed and installed the node module Rxjs and need to reference it in my client-side...this is where things are getting unclear for me.</p>
<p>I've seen some postings that I should be using the "map" feature of System.config to map to the node_module in conjunction with the packages feature in the index.html file, but I am unable to get that to work. The app launches, but the client side app component doesn't appear to be able to see it. It's almost like an out-of-scope issue. (Sorry, I do not have the exact error message handy). If I use map, am I allowed/supposed to map it to its home in the node_modules directory or should I be putting the needed typescript files within the directory structure of Public?</p>
<p>I've also seen some postings where you can just move the js file to say the lib directory and reference it as a javascript src file in index.html...but I'm getting no joy there either.</p>
<p>I believe that part of the issue is likely ties to requires/dependencies within the various node_modules themselves, but I'm not sure how to deal with that.</p>
<p>So, what is the right/best way to set this all up and integrate the node_modules that I need? Is it simply not possible to reference modules within the node_modules from a client-side app and I need to bring all of the .d.ts/ts/js files into the public scope? If so, do I need to investigate the references within each ts file and bring everything over?</p>
<p>I understand that I may not be providing all or perfectly specific details here, but I hope you can see the higher-level best-practices question that I'm posing here and push me in the right direction.</p> | 3 |
Explanation of android code | <p>i found a code that converts a hex string to binary. This is the code ` </p>
<pre><code>public static byte[] hexStringToBytes(String hexString) {
if (hexString == null || hexString.equals("")) {
return null;
}
hexString = hexString.toUpperCase();
int length = hexString.length() / 2;
char[] hexChars = hexString.toCharArray();
byte[] d = new byte[length];
for (int i = 0; i < length; i++) {
int pos = i * 2;
d[i] = (byte) (charToByte(hexChars[pos]) << 4 | charToByte(hexChars[pos + 1]));
}
return d;
}
public static byte charToByte(char c) {
System.out.println((byte) "0123456789ABCDEF".indexOf(c));
return (byte) "0123456789ABCDEF".indexOf(c);
}
</code></pre>
<p>The code works perfectly but i am not able to understand the following line of code ie how it is working <code>d[i] = (byte) (charToByte(hexChars[pos]) << 4 | charToByte(hexChars[pos + 1]));</code>. Can anyone explain what this code is doing. It is going very difficult to work on binary code. Also can anyone provide a link for some documentation that explains with some example how to work with binary codeing.</p> | 3 |

Non-blocking write to response from Mongo in JSON format | <p>I am using Node/Express.js so that the GET route will retrieve all documents from a Mongo database (simple enough). I am able, as the code will show, to accomplish this in a non-blocking way. However, when I uncomment the line that sets the response to JSON format, I get a syntax error - because while each document is in JSON format, the aggregation of the documents aren't in JSON format. How can I keep the non-blocking data flow, but send them as <code>application/json</code></p>
<p>I include below the GET route and also the function I am using to get the items form the mongo database.</p>
<p>GET route:</p>
<pre><code>app.get('/people', function(req, res){
//res.set('Content-Type', 'application/json');
mongoDriver.get(null, function(err, code, document){
res.status(code);
if(err) {
res.write(JSON.stringify(err));
} else if(document){
res.write(JSON.stringify(document));
}
if(!document){
res.end();
}
});
});
</code></pre>
<p>relevant portion of my mongo implementation.</p>
<pre><code>var cursor = db.collection(self.collection).find(data);
cursor.each(function(err, doc) {
if(err) {
return callback(err, 500);
} else if (doc !== null) {
return callback(null, 200, doc);
} else {
db.close();
return callback(null, 200, null);
}
});

Unity3D - Detect a vertex on planet mesh without cubes | <p>I have a planet mesh that I am generating procedurally (based on a random seed). The generator creates tectonic plates and moves them creating the land masses, mountains and water depressions you see below; ~2500 points in a planet. The textured surface is just a shader.</p>
<p><a href="https://i.stack.imgur.com/41P6J.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/41P6J.jpg" alt="enter image description here"></a></p>
<p>Each vertex will have information associated with it, and I need to know which vertex they are pointing at to relay this information.</p>
<p>I am looking for a way identify which vertex they are pointing at. The current solution is to generate a cube at each vertex, then use a collider/Ray to identify it. The two white cubes in the picture above are for testing.</p>
<p>What I want to know is if there is a better way to identify the vertex without generating cubes?</p> | 3 |
Recurssion Depth Exceeded While calling an python object | <p>I am making a web crawler for which I am using the following two functions:</p>
<pre><code>#Each queued link is the new job
def create_jobs():
for link in file_to_set(QUEUE_FILE):
queue.put(link)
queue.join()
crawl()
#Check if there are items in the queue then solve them
def crawl():
queued_links = file_to_set(QUEUE_FILE)
if len(queued_links)>0:
print(str(len(queued_links))+' links in the queue')
create_jobs()
</code></pre>
<p>here crawl is called first. Sometimes while crawling the page it shows maximum recurssion depth exceeded whereas sometimes not. (I am running the same script again). Can someone explain me what's the problem?</p>
<p>Please note that the number of links that I need to crawl is around 100 only which is less than the limit for python.</p> | 3 |
JAX WS async client: capture WS-Addressing 202 accepted | <p>I have to invoke several webservices using WS-Addressing.
When invoking a webservice, the ReplyTo is set to a callback endpoint implemented by me.</p>
<p>The client is generated from the target WSDL using async with</p>
<pre><code><enableAsyncMapping>true</enableAsyncMapping>
</code></pre>
<p>which generates the <code>Async</code> version for each webservice with the following signature:</p>
<pre><code>javax.xml.ws.Response<SampleWebServiceOutput> sampleWebService(SampleWebServiceInput input)
</code></pre>
<p>When invoking <code>sampleWebService</code> like, </p>
<pre><code>Response<SampleWebServiceOutput> response = clientWsPort.sampleWebService(input);
</code></pre>
<p>if the request is sucessful, the server will return <code>202 Accepted</code> however I can't figure out how to get it.</p>
<p>If I use <code>response.get()</code>, it will block forever since the response is sent to my callback url (WSA-Addressing Reply To)</p>
<p>Any clues how to know for sure if the server successfully accepted the request ?</p>
<p>Thank you.</p> | 3 |
Jquery result display issue | <p>I am trying to create a bmi calculator and tried the following .</p>
<pre><code>$(document).ready(function() {
// Convert ft to inches
function convertHeight(ft) {
return ft * 12;
}
// calculate total height
function showbmi() {
var weight = document.getElementById('weight').value * 1;
var height_ft = document.getElementById('height_ft').value * 1;
var height_in = document.getElementById('height_in').value * 1;
var height = convertHeight(height_ft) + height_in;
var female_h = (height * height) / 30;
var male_h = (height * height) / 28;
var gender;
var x = document.getElementsByName("gender");
for (var i = 0; i < x.length; i++) {
if (x[i].checked == true) {
gender = x[i].value;
break;
}
}
var bmi = "?";
if (gender == "female") {
bmi = (Math.round((weight * 703) / (height * height)));
if (isNaN(bmi)) bmi = "?";
} else {
bmi = (Math.round((weight * 703) / (height * height)));
if (isNaN(bmi)) bmi = "?";
}
var bmi_msg = "?";
if (bmi < 15) {
bmi_msg = "Very severely underweight";
} else if (bmi <= 16) {
bmi_msg = "Severely underweight";

bmi_msg = "Obese Class II (Severely obese)";
} else {
bmi_msg = "Obese Class III (Very severely obese)";
}
$("#result").text(bmi);
return bmi;
$("#comment").text(bmi_msg);
return bmi_msg;
}
//bmi infos
//finish
$("form#calc input").bind("keydown", function() {
setTimeout(function() {
showbmi();
}, 100);
return true;
});
$("form#calc input").bind("change", function() {
showbmi();
});
$("form#calc radio").bind("change", function() {
showbmi();
});
$("form#calc").bind("submit", function() {
showbmi();
return false;
});
});
</code></pre>
<p>The bmi displays correctly, but the messages forbmi values are not displaying. i checked the console and it says code unreachable.
Can somebody throw some light where I am goin wrong, and How I can improve this code.</p> | 3 |
How to split repeating pattern? | <p>I have a string that repeats a pattern. I have a regular expression that matches the pattern, but I would like to split them instead.</p>
<pre><code>$target = 'a1v33a33v55a2v43';
</code></pre>
<p>I would like to split them into a1v33, a33v55, and a2v43. Basically, I want to split the string into an array of ['a1v33', 'a33v55', 'a2v43'].</p>
<p>I've tried the following code, but it only matches the pattern. How can I split them instead?</p>
<pre><code>$target = 'a1v33a33v55a2v43';
$pattern = '/(a[0-9]+v[0-9]+)*$/im';
preg_match($pattern, $target, $match);
echo '<pre>';
print_r($match);
