If statements in Racket | <p>I am trying to construct a function "number-crop" which takes three arguments x a b. If x is to the left of the closed interval [a, b] on the number line, then return a. If x is to the right of the interval, then return b. Otherwise, just return x. This is what I have: </p>
<pre><code>(define (number-crop x a b)
(if (max x a b) x b)
(if (min x a b) x a))
</code></pre>
<p>I am returned with the error, "define: expected only one expression for the function body, but found 1 extra part". I am new to Racket so I am still trying to understand how if statements work within the language.</p> | 1 |

Unable to deserialize ZonedDateTime using Jackson | <p>I am using Jersey with Jackson as JSON provider. I am able to serialize <code>ZonedDateTime</code> to JSON but when I want to deserialize it gives me error as follows.</p>
<p>Could you please help me tell the exact configuration required to get this deserialization work.</p>
<blockquote>
<p>Caused by: com.fasterxml.jackson.databind.JsonMappingException: Can not instantiate value of type [simple type, class java.time.ZonedDateTime] from String value ('2016-01-21T21:00:00Z'); no single-String constructor/factory method</p>

<p>My mapper configuration is as follows:</p>
<pre><code>@Provider
public class ObjectMapperContextResolver implements ContextResolver<ObjectMapper> {
private final ObjectMapper MAPPER;
public ObjectMapperContextResolver() {
MAPPER = new ObjectMapper();
//This would add JSR310 (Datetime) support while converting date to JSON using JAXRS service
MAPPER.registerModule(new JavaTimeModule());
//Below line would disable use of timestamps (numbers),
//and instead use a [ISO-8601 ]-compliant notation, which gets output as something like: "1970-01-01T00:00:00.000+0000".
MAPPER.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
}
@Override
public ObjectMapper getContext(Class<?> type) {
return MAPPER;
}
}

Regular expression for detecting first name and/or last name | <p>Please help me to build a pattern in the text input field like that,</p>
<pre><code><input name="BusinessOwner" type="text" id="BusinessOwner" pattern="?">
</code></pre>
<p>But the rule is that this input field only allow English <strong>Small letter</strong> and/or <strong>Capital letter</strong>(include/Exclude space) and no <strong>Numeric Digits</strong>. So according to the rule,</p>
<pre><code>Adam Smith => valid
adam => valid
AB CD => valid
abcd12 => Invalid
abcd 12 => Invalid
</code></pre>
<p>Please help me to build the pattern.</p> | 1 |
Why is change detection not working in my Angular 2 code? | <p>What am I doing wrong here. I have created a service that has one property that I am updating with <code>setInterval</code>. </p>
<p>I am injecting this service into a component and want the component to watch the property for changes to update the screen. But only the initial value for <code>numCount</code> is shown and it is never updated. </p>
<p>Example:</p>
<p>Here is a test service I created</p>
<pre class="lang-ts prettyprint-override"><code>export class TestService {
numCount: number;
constructor() {
this.numCount = 0;
var self = this;
setInterval(function() {
self.numCount++;
console.log('from service', self.numCount);
}, 500);
}
}
</code></pre>
<p>Here is the component</p>
<pre class="lang-ts prettyprint-override"><code>export class MyComponentView implements OnChanges {
displayString: string;
constructor(testService: TestService) {
this.displayString = testService.numCount.toString();
}
ngOnChanges(changes) {
console.log(changes); // nothing logs out, even though the testService.numCount is being incremented in the class.
}
}
</code></pre>
<p>If you see here, <code>testService.numCount</code> is being increased by one every half second. But when I display it on screen through the component, it does not update. How can I watch the data from the injected service so it updates on screen?</p>
<p>I am displaying the <code>displayString</code> on the screen and the number does not change.</p> | 1 |
Oozie shell action: exec and file tags | <p>I'm a newbie in Oozie and I've read some Oozie shell action examples but this got me confused about certain things.</p>
<p>There are examples I've seen where there is no <code><file></code> tag.</p>
<p>Some example, like in Cloudera <a href="http://blog.cloudera.com/blog/2013/03/how-to-use-oozie-shell-and-java-actions/" rel="noreferrer">here</a>, repeats the shell script in file tag:</p>
<pre><code><shell xmlns="uri:oozie:shell-action:0.2">
<exec>check-hour.sh</exec>
<argument>${earthquakeMinThreshold}</argument>
<file>check-hour.sh</file>
</shell>
</code></pre>
<p>While in <a href="https://oozie.apache.org/docs/4.1.0/DG_ShellActionExtension.html#Shell_Action" rel="noreferrer">Oozie's website</a>, writes the shell script (the reference <code>${EXEC}</code> from job.properties, which points to script.sh file) twice, separated by #.</p>
<pre><code><shell xmlns="uri:oozie:shell-action:0.1">
...
<exec>${EXEC}</exec>
<argument>A</argument>
<argument>B</argument>
<file>${EXEC}#${EXEC}</file>
</shell>
</code></pre>
<p>There are also examples I've seen where the path (HDFS or local?) is prepended before the <code>script.sh#script.sh</code> within the <code><file></code> tag.</p>
<pre><code><shell xmlns="uri:oozie:shell-action:0.1">
...
<exec>script.sh</exec>
<argument>A</argument>
<argument>B</argument>
<file>/path/script.sh#script.sh</file>
</shell>
</code></pre>
<p>As I understand, any shell script file can be included in the workflow HDFS path (same path where workflow.xml resides).</p>
<p>Can someone explain the differences in these examples and how <code><exec></code>, <code><file></code>, <code>script.sh#script.sh</code>, and the <code>/path/script.sh#script.sh</code> are used?</p> | 1 |
Need help overriding a WPF button style background color. | <p>I have the below code set for a custom button. But I want to change the background for a single button. </p>

Parsoid doesn't start | <p>I installed parsoid from its official repository, and configured it correctly by adding my Mediawiki API to <code>/etc/mediawiki/parsoid/settings.js</code>. I also removed the Interwiki options from my <code>/usr/lib/parsoid/src/api/localsettings.js</code>file, because they seem to be replaced by the parsoidConfig.setMwApi option in the settings.js file.</p>
<p>When running <code>nodejs /usr/lib/parsoid/src/api/server.js</code> from the command promt, I get the following error message:</p>
<pre><code>[fatal][worker][4915] uncaught exception object is not a function

Can someone explain how to select Multiple Values from an Access 2016 Combo box Control | <p>I have a combo box control on a form that allows me to choose one option only from a list of options.</p>
<p>I would like to be able to choose multiple options from this list(similar to how a drop down menu works on an access table field)</p>
<p>I know it is possible from a list box but this takes up a lot of room on my form because the list box must stay open. </p>
<p>It says in this article <a href="https://support.office.com/en-us/article/Use-a-list-that-stores-multiple-values-c8d15127-3641-45fc-aa2d-a3943d355e89" rel="nofollow">https://support.office.com/en-us/article/Use-a-list-that-stores-multiple-values-c8d15127-3641-45fc-aa2d-a3943d355e89</a> that its possible but I cannot get it to work.

React Native MapView rotate map with camera heading | <p>I am trying to rotate a map in React Native's <strong><MapView></strong> but haven't been able to find a description on how to rotate a map according to the heading of the camera. The tutorial states:</p>
<blockquote>
<p>When this property is set to true and a valid camera is associated with the map, the camera’s heading angle is used to rotate the plane of the map around its center point. </p>
</blockquote>
<p>So I came as far as:</p>
<pre><code><MapView
style={styles.map}
onRegionChange={this._onRegionChange}
onRegionChangeComplete={this._onRegionChangeComplete}
region={this.state.mapRegion}
annotations={this.state.annotations}
rotateEnabled={true}

<p>But there is no explanation on how a camera is associated with the map.</p>

Android Marshmallow (rooted): How to read / write any file | <p>I recently updated to Marshmallow (Cyanogmod CM13) and, due to the new permissions regime, a lot of my apps no longer work.</p>
<p>Note that these apps are not on the Play Store and are for my own personal use. So security is not much of a problem - I'll let my apps access whatever I want them to access.</p>
<p>The problem is how to achieve that.</p>
<p>I've tried doing a "su -c chmod" to modify the permissions but that does not work.</p>
<p>Other apps (eg Jota+) can browse to and write to a file. How do they do that? (Yes, I've tried searching but have not hit on the right search terms - if the answer is "out there".)</p>
<p><strong>EDIT</strong>: The sdcard has been "adopted" and all relevant files transferred to it.</p> | 1 |

Its IP address is 192.168.56.128 and my Mac (host) got 192.168.56.1. Guest's default gateway is automatically set to 192.168.56.2 and is able to ping google. Host's Wi-Fi IP is 192.168.0.2,</p>
<p>I've configured my Wi-Fi router with following routing table to forward packets of 192.168.56.0 to 192.168.0.2 (my Mac)</p>
<pre><code>pi@raspberrypi ~ $ route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 172.16.4.1 0.0.0.0 UG 0 0 0 eth0
172.16.4.0 * 255.255.252.0 U 0 0 0 eth0
192.168.0.0 * 255.255.255.0 U 0 0 0 wlan0
192.168.56.0 192.168.0.2 255.255.255.255 UGH 0 0 0 wlan0
192.168.57.0 192.168.0.2 255.255.255.255 UGH 0 0 0 wlan0
</code></pre>
<p>But I'm unable to ping guest from any other device on the Wi-Fi network (192.168.0.0). So it's obvious that my Mac running OS X El Capitan is not forwarding the packets from 192.168.0.0 to 192.168.56.0</p> | 1 |
Laravel Eloquent Birthdays Query to get Date Column based on Date and Month only | <p>I have a <code>date()</code> column in mysql which has the Date of Birth in mysql’s <code>YYYY-MM-DD</code> format:</p>
<pre><code>$table->date('dob')->nullable();
</code></pre>
<p>I am trying to query this table so it lists all users who are having birthdays from today till next 7 days. I have something like this right now:</p>
<pre><code>$date = new Carbon;
$today = $date->format('Y-m-d');
$futureDays = $date->addDays(7)->format('Y-m-d');
$birthdays = SiteUsers::where('dob', '>=', $today)
->where('dob', '<=', $futureDays)
->orderBy('dob', 'ASC')
->get();
</code></pre>
<p>The problem with the above query is that it only lists the users having DOB with the exact dates in this year only which is not right. What I really want is to list the users having birthdays irrespective of the year they were born by matching only the ‘date’ and ‘month’ and ignoring the ‘year’.</p>
<p>I don’t know how to achieve that. Can someone help me out please…</p> | 1 |
How to store special characters in Hive? | <p>I've been playing around with Spark, Hive and Parquet, I have some data in my Hive table and here is how it looks like ( warning french language ahead ) : </p>
<pre><code>Bloqu� � l'arriv�e NULL
Probl�me de connexion Bloqu� en hub
</code></pre>
<p>Obviously there's something wrong here.</p>
<p>What I do is : I read a teradata table as a dataframe with spark, I store it as a parquet file and then I use this file to store it to hive, here's my create table script : </p>
<pre><code>CREATE TABLE `table`(
`lib` VARCHAR(255),
`libelle_sous_cause` VARCHAR(255),
)
STORED AS PARQUET
LOCATION
'hdfs://location';
</code></pre>
<p>I don't really know what cause this, it might be caused by some special encoding between Teradata > parquet or Parquet > Hive, I'm not sure.</p>
<p>Any help will be appreciated, thanks.</p> | 1 |
Instantiate a fragment with a Custom Object Array List | <p>I'm trying to instantiate a fragment "sending" a custom object array list, but I can't find the exact way to do it. I think I may have to use <code>Serializable</code> or <code>Parcelable</code> (as seen in another answer), but I'm not sure how to implement it even after reading that answer.</p>
<p>Can someone help me? Thanks in advance.</p>
<p>Code to instantiate</p>
<pre><code>Fragment f = new Fragment();
ArrayList<IconsCategory> category = Utils.getCategory();
ArrayList<IconItem> icons = category.getIconsArray();
f = IconsFragment.newInstance(icons);
return f;
</code></pre>
<p>Code in fragment to create the instance:
I know <code>args.putArrayList()</code> method doesn't exist, I just wrote it to show how I expect to be able to code it.</p>
<pre><code>public static IconsFragment newInstance(ArrayList<IconItem> list) {
IconsFragment fragment = new IconsFragment();
Bundle args = new Bundle();
args.putArrayList(list); // here's where the code is supposed to go
fragment.setArguments(args);
return fragment;
}
</code></pre>
<p>IconsCategory class:</p>
<pre><code>import java.util.ArrayList;
public class IconsCategory {
private String name;
private ArrayList<IconItem> iconsArray = new ArrayList<>();
public IconsCategory(String name, ArrayList<IconItem> iconsArray) {
this.name = name;
this.iconsArray = iconsArray;
}
public String getCategoryName() {
return this.name;
}
public ArrayList<IconItem> getIconsArray() {

Insufficient privileges to complete the operation when using an Azure service principal to create Azure resources | <p>I would like to use a service principal account to run a Powershell script that creates Azure resources, as suggested in <a href="http://blog.davidebbo.com/2014/12/azure-service-principal.html" rel="nofollow">this article about doing so when provisioning via TeamCity</a></p>
<p>I am able to create the service principal and assign it the 'Owner' role on the subscription, so in theory it should have rights to do anything in the Azure account. (I will adjust the rights later to just what is required by the principal.) The commands are basically the following:</p>
<pre><code>Login-AzureRmAccount # using my Azure admin account
$azureAdApplication = New-AzureRmADApplication -DisplayName "Deploy" -HomePage "https://deploy" -IdentifierUris "https://deploy" -Password "password"
New-AzureRmADServicePrincipal -ApplicationId $azureAdApplication.ApplicationId
New-AzureRmRoleAssignment -RoleDefinitionName Owner -ServicePrincipalName $azureAdApplication.ApplicationId
$subscription = Get-AzureRmSubscription
$creds = Get-Credential
Login-AzureRmAccount -Credential $creds -ServicePrincipal -Tenant $subscription.TenantId
</code></pre>
<p>However, when I then run a Powershell script that provisions resources, I get the following warnings when creating a Key Vault: </p>
<ul>
<li>Insufficient privileges to complete the operation</li>
<li>Access policy is not set. No user or application have access permission to use this vault. Please use Set-AzureRmKeyVaultAccessPolicy to set access policies</li>
</ul>
<p>I don't get these warnings when creating the Key Vault via my own admin account. How do I give a service principal sufficient privileges to be able to create resources in an Azure subscription without getting permissions issues?</p> | 1 |
Java JNI error java.lang.UnsatisfiedLinkError: xxxx()V | <p>I have had a rough time with <code>JNI</code> today, basically what I want to do is integrate <code>OpenAlpr</code> to my <code>Java</code> project, I am using precompiled binaries which work perfectly when I run the <code>java_test.bat</code> file. At first Java kept on telling me it could not locate <code>openAlprJni</code> then I added the path to the <code>dlls</code> to my build path and system path, after which I started experiencing the <code>openAlprJni.Alpr.initialize(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)V</code> which according to documentation means the library itself is not ok, but it is ok since the test program is running, I have looked at various forums and even talked to the author of <code>OpenAlpr</code> but still cannot resolve this issue, is there anybody here who has had a similar problem help me fix this? thanks in advance.</p> | 1 |

<p>There are logging configurations in the <code>properties</code> files the Kafka server and Zookeeper look at, but I've assumed these do not affect Kafka clients. Changing some of the logging configurations in these files, and restarting the Kafka server and Zookeeper so those files are reloaded, has not solved the problem.</p>

AWS data into Excel? | <p>I have a client who has asked me to take a look at the spreadsheet that they use for manipulating AWS data in order to import sales invoices into Xero....I'm just wondering if it's possible to directly query AWS from Excel?...this would streamline the process by cutting out the manual AWS export plus I would be able to create a query that puts the data into the format that Xero needs to see.</p>
<p>...moving on from this, I guess the next logical step would be to create an API that Xero can hook up to....unless this is already a thing?</p>

Google Sheet script to automatically calculate a countdown | <p>I haven't coded in decades, and I'm looking for a way to automate my current "countdown" spreadsheet. I currently do things in an ugly, error-prone and roundabout way, a very small script should be able to make it much better.</p>
<p><b>Goal:</p></B>
- Type in a duration in hours (typically, between 0 and 1,000) in a cell</p>
- One cell below, get a running countdown of how many hours remain. </p>
<p><B>Current situation:</B></p>
I've got the sheet set up to auto-recalc every hour, which is fine
then a 4-cells setup, repeated over multiple columns to track several timers:</p></p></p>
<ul>
<li>1st cell (B2) is the input cell to type in the duration in hours</p></li>
<li>2nd cell (B3) is =now()+B2/24 , that calculates the expected date of completion resulting from B2</p></li>
<li>3rd cell (B4) contains a hard copy of B3's value so that recalcs don't change that "firm expected completion" date. I have to copy + pastevalue from B3 to B4 every time I modify B2, which is the main issue with that setup</p></li>
<li>4th cell (B5) is =(int(B4)-int(now()))*24+hour(B4)-hour(now()) and is the running countdown I watch out for. Had to use int() not day() otherwise I get bugs when the start and completion dates are not the same month. </p></li>
</ul>
<p><B>What I'd like: </p></p></B>
- To get rid of the 2 intermediate cells and the cumbersome + error-prone manual copy-pastevalue between them.</p>
- An auto-trigger script that directly fills in B5 (actually, that would change to B3) with the countdown, using a formula that's probably</p>
(int(B2+$datetime_of_B2_modification) - int(now() )*24 + hour(B2+$datetime_of_B2_modification) - hour(now)). </p>
B2 is a direct reference to B2's value, $datetime_of_B2_modification is a value that is calculated each time I modify B2, and only then (not when the sheet is recalced, not when I hover over B2 but don't actually modify it) and is then harcoded into B5's formula; now() is gSheet's actual function that returns now's datetime.</p>
- ideally, that autotrigger script automatically creates that formula one cell below the one were I enter the hours duration, ie I don't have to make a different script for every column in my spreadsheet, it creates the formula "one cell below", not at a fixed cell.</p></p></p>
<p>My decades-old skills are rusty, I've been struggling to get started but I'm going nowhere. If someone could magically whip up that script, I'd be very grateful !</p></p></p>
<p>Best regards, Olivier</p>
<p>Thinking of it, a script to automate the copy+pastevalue step w/o changing anything else would be a nice first step. Getting rid of the 2 extra rows isn't that critical, though it would be nice.</p>

// check the cell has actually been modified
if (e.value = e.oldValue) return;
//OK, so we're in a valid source cell, and it HAS been modified
// now let's build the formula string
var sourcevalue = sourcecell.getValue()
var enddate = sourcevalue/24 + now()
var enddateday = int (endate) * 24
var endatetime = hour (enddate)
?? var countdownformula = '=' + (enddateday + enddatehour) + '- (int(now())*24) - hour(now())'
//and now let's put it in the destination cell
?? var destcell = sourcecell + ????? (one row down from active cell)
?? destcell.setformula(countdownformula)

XWPF - remove cell text | <p>I have a .docx file that contains a single table. I want to remove all text from rows 2 to the end.
However the method <code>myTable.getRow(somecounter).getCell(somecounter2).setText("")</code> doesn't work as it only concatenates " " to the existing value.
I also tried making a XWPFRun and doing <code>run.setText("")</code> created from <code>myTable.getRow(sc).getCell(sc2).getParagraphs().get(0).createRun()</code> but it doesn't work aswell.</p>
<p>Also tried the solution from <a href="https://stackoverflow.com/questions/28926195/apache-poi-xwpf-does-not-replace-but-concatenates">this thread</a>, no luck this time :(</p>
<p>Any ideas how to easily remove text from the cell?
My idea is to make a new table from scratch and fill it with content but it seems really arduous.</p> | 1 |

Creating style alias in CSS on HTML page | <p>I am wanting to do selectively stop the line feeds associated with the < p> command on a dynamically built HTML page and am using a style to do this. I know that </p>
<pre><code> p {
display: inline
}
</code></pre>
<p>can do this, but I do not want to continually add this tag throughout the page.</p>
<p>Is there a method where I can create an alias of the p tag, or somehow create another tag that will invoke the style.</p>
<p>For instance (and I know that this code won't work), something like</p>
<pre><code> <style type="text/css">
stop-p-lf {
p {
display: inline
}
}
</style>
</code></pre>
<p>then in my HTML I just use the tag like this..</p>
<pre><code> <stop-p-lf>the next p tag will not line feed <p>
but the one after this</stop-p-lf> <p> will
</code></pre>
<p>I'm hoping to use these tags to ease readability and to reduce the amount of coding throughout the html.</p>
<p>Is there a way of doing this?</p> | 1 |
Django static templatetag not displaying SVG | <p>I'm trying to use django's <code>static</code> templatetag to display an SVG, but it doesn't seem to recognize the SVG as a valid image url. This is what I currently have:</p>
<h2>settings.py</h2>
<pre><code>import mimetypes
mimetypes.add_type("images/svg+xml", ".svg", True)
</code></pre>
<h2>landing.html</h2>
<pre><code>{% load staticfiles %}
<img src="{% static 'images/right-arrow.svg' %}" />
</code></pre>
<p>At least in my view.py, it recognizes the SVG mimetype:</p>
<h2>views.py</h2>
<pre><code>print(mimetypes.guess_type(static('images/right-arrow.svg')))
# returns ('images/svg+xml', None)
</code></pre>
<p>The SVG does display in a non-django page, and it will download the SVG if I try to open the SVG path in a new browser tab. </p>
<p>I'm currently using python 3.4 and django 1.8.4.</p> | 1 |
COPY NULL values in Postgresql using psycopg2 copy_from() | <p>This seems like a rather popular question, but all the answers around here did not help me solve the issue... I have a Postgresql 9.5 table on my OS X machine:</p>

print cpy
cpy.seek(0)
curs.copy_from(cpy, 'test')
test_copy(connection, [('a', None), ('b', None)])

Need to transfer multiple files from client to server | <p>I'm recently working on a project in which I'm basically making a dropbox clone.

How to put R Markdown chunks in different HTML-tabs? | <p>I have an R markdown page with a lot of chunks. Is it possible to render an HTML-page in which the chunks appear in different tabs?</p>

Can I remove event listeners with a Chrome extension? | <p>In Chrome's dev tools, there's a lovely interface where you can see all the event listeners attached to a given DOM element, and remove any of them as you see fit. Here's a screenshot (arrow added for emphasis):</p>
<p><a href="//i.stack.imgur.com/DCkKG.png" rel="noreferrer"><img src="//i.stack.imgur.com/DCkKG.png" alt="Removing an event listener with Chrome dev tools"></a></p>
<p>I'd like to write a Chrome extension that automatically removes event listeners from any web page (I'm trying to write a Chrome extension to disable smooth scrolling on any website that tries to force it upon you -- I figure removing the 'wheel' listener from <code><body></code> is the most direct route to do this). Is there any JavaScript API available for accessing and modifying this list of event listeners from a Chrome extension, or is it limited to the dev tools GUI?</p>
<p>To be clear, I'm aware of <a href="https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/removeEventListener" rel="noreferrer">removeEventListener()</a>, but that method requires that you have a reference to the original listener object -- I have no such reference, so that method won't suit my purposes.</p> | 1 |

WinSCP Disable ResumeSupport in PowerShell | <p>I am using WinSCP to write to connect a SQL Server to an SFTP server. I am trying to write a file to an SFTP server where I only have write access, not modify. I am having a problem because I get back</p>
<blockquote>
<p>Cannot create remote file '/xxx.filepart'.</p>
</blockquote>
<p>The documentation suggests this is because I do not have modify access to the target directory. I did this <em>WinSCP -> Preferences -> Endurance -> Disable</em><br>
I checked the <code>winscp.ini</code> file and <code>ResumeSupport</code> is <code>2</code> (I believe this means disabled). I ran <code>"echo $transferOptions.ResumeSupport"</code> and it says that it is in a default state.</p>
<p>I have checked this documentation:<br>
<a href="https://winscp.net/eng/docs/ui_pref_resume" rel="nofollow">https://winscp.net/eng/docs/ui_pref_resume</a><br>
<a href="https://winscp.net/eng/docs/library_transferoptions#resumesupport" rel="nofollow">https://winscp.net/eng/docs/library_transferoptions#resumesupport</a></p>
<p>However, I don't see a PowerShell example, just C#.</p>
<p>I have tried various permutations of <code>$transferOptions.ResumeSupport.State = Off</code>, <code>$transferOptions.ResumeSupport.Off</code>, and whatnot. One of these says that it's read-only.</p>
<p>I know <code>$transferOptions</code> is a variable here but it comes from the default script. The object determines transfer options <code>$transferOptions = New-Object WinSCP.TransferOptions</code></p>
<p>Thanks in advance for help </p>
<p>edit: The overall problem is I only have write access to the server, but not modify. I am getting a new error: "Cannot overwrite remote file '/xxx'.$$. It looks like the dollar signs are some sort of temp file that it's trying to create. Is there a way to disable whatever setting is causing this? </p> | 1 |
Postgresql postmaster takes very long time to start | <p>My situation in Postgres 9.1 is that
I had some running queries which take a lot of memory, then I restarted Postgres immediately. After that I used postmaster to start it again.</p>
<p>/usr/pgsql-9.1/bin/postmaster -p 5432 -D /var/lib/pgsql/9.1/data</p>
<p>However, it got stuck for a very long time without starting successfully.</p>
<p>From Postgres documentation, when we restart server immediately, it may prevent postmaster from freeing the system resources (e.g., shared memory and semaphores).
So what should I do now? or just wait for postmaster starting?</p> | 1 |

Compress a HttpWebRequest using gzip | <p>I am developing a <code>.NET 4.0</code> Console Application to serve as a <code>SOAP Web Service</code> client which will send data (POST) through to a third-party. I have no control over the web service on the server-side. The third-party did provide <code>WSDL's</code> to use, and I was able to import them and use them with reasonable success. However, there is a requirement to compress the request message using <code>gzip</code>, and I could not for the life of me figure out how to do that using the proxy services.</p>
<p><a href="https://stackoverflow.com/questions/9787923/using-compression-with-c-sharp-webservice-client-in-visual-studio-2010?lq=1">This topic</a> here on SO, led me to believe that without having control over both the client and server code, the request is unable to be compressed. As a result of this finding, I wrote the code in my application to manually create the <code>SOAP XML</code> in a <code>XDocument</code> object; then, populated the values from the <code>WSDL</code> proxy class objects which I had previously coded my client application to use.</p>
<p>The first requirement for this client, is to send the message compressed via <code>gzip</code>. After some research, I have seen answers as simple as just adding the <code>HttpRequestHeader.AcceptEncoding, "gzip, deflate"</code> to the request header. Unfortunately, doing that that didn't appear to work.</p>
<p>Currently, the certificate which I am retrieving is not the real certificate. I am trying to make the code as sound as I can before deploying to a test environment to do the actual service testing.</p>
<ol>
<li>Is there a way to compress the request via the proxy call (<code>wsdl</code>)?</li>
<li>Is there something I am missing in order to properly compress the <code>HttpWebRequest</code>?</li>
<li>Might there be something else going wrong which would result in the error message to be returned?<br>
<em>I would expect a different message pertaining to authentication being invalid if the request itself was OK</em>.</li>
<li>Is there a way the compression can be done through the <code>app.config</code>?</li>
</ol>
<p>The next set of requirements I'm a little confused on how to handle/what to do. Under the assumption that what I have set the <code>ContentType</code> of the request to, how (and what) do I add in order to add the <code>content-transfer-encoding</code> piece to the request? If the <code>ContentType</code> is incorrect, how should I add this information as well?</p>
<blockquote>
<p>The content type for the SOAP Evenlope with MTOM encoded attachment must be "application/xop+xml" and the content-transfer-encoding must be 8-bit.</p>
</blockquote>
<p>I've gone through a few iterations of the code below, however, I believe the relevant snippets are the code at its simplest form. Please let me know if there is other information that would be helpful.</p>

React Native - Sending events from Native to JavaScript in AppDelegate (iOS) | <p>In my React native app, I am trying to send events from Native Code to JavaScript in the AppDelegate. To do this I call:</p>
<pre><code>[self.bridge.eventDispatcher sendAppEventWithName:@"EventReminder"
body:@{@"name": eventName}];
</code></pre>
<p>In my app delegate. Of course to do this I need to import:</p>
<h1>import "RCTBridge.h"</h1>
<h1>import "RCTEventDispatcher.h"</h1>
<p>and synthesize the bridge</p>
<pre><code>@synthesize bridge = _bridge;
</code></pre>
<p>But event after this, the bridge variable doesn't exist. To make this error go away I made my AppDelegate conform to the RCTBridgeModule protocol like so:</p>
<pre><code>AppDelegate : UIResponder <UIApplicationDelegate, RCTBridgeModule>
</code></pre>
<p>And then in my AppDelegate.m, I did:</p>
<pre><code>RCT_EXPORT_MODULE()
</code></pre>
<p>After all that my bridge is finally not erroring, but Everytime I use it in the AppDelegate, it is nil.</p>
<p>Where am I going wrong?</p>

<pre><code>DefaultCollection
Team Project Root
|
----Web Apps Folder
|
----Web Application 1
|
----WebApplication1.csproj
|
----Web Service 1
|
----Web Service 2
|
----Winforms Folder
|
----Winforms App 1
|
----Winforms App 2
|
----Common Files Folder
MySolution.sln
</code></pre>
<p>MySolution.sln is in the Team Project Root, and the solution contains all the various applications within it which are a mixture of web apps, web services and Windows applications.</p>
<p>The problem I have is that I am new to branching and I want to branch the entire solution, but I think that the way my SLN file is in the root will make this difficult?</p>
<p>What I need is to have Web Application 1 branched, and I understand I can branch Web Application 1. But in order to run it I would need to create a new solution file to contain it which would mess things up.</p>
<p>Is there a way I can Branch the entire solution from this scenario, or will I have to try to re-structure things somehow?</p> | 1 |
laravel 5.2 will freak out if table exists when running migrations | <p>I need a work around or a check to see if the table exists.</p>
<p>Situation:</p>
<p>I have a test site and a production site, on the test site I created and ran a task that over time created 25million records. these records were then exported from the test database and imported into the production so I don't have to re-run the task over again. </p>
<p>this allowed me to switch out some the logic to now say, do the same fetch but check to make sure the record doesn't already exist, vastly increeasing the speed of this whole task (the task spawns about 125 ish jobs that do 100 fetches split up into 18 concurrent connections) So this takes a while.</p>
<p>Because of this on production the migration will be like "uh this table exists ... sorry crash time"</p>
<p>So I want to say "if table exists ignore the migration, else run the migration for create"</p>
<p><strong>ideas?</strong></p> | 1 |
WPF DataGrid CheckBox Check/Uncheck with single click | <p>I need check and uncheck of CheckBox using spacebar key in a single click.I tried like below.</p>

<p>With mouse I am able to check/uncheck in a single click.
But the same thing I am not able to do it with spacebar key.
The key down event is firing only when I press tab key twice.

Flickering during the transition between views on iOS (ionic framework) | <p>This is the video of the issue: <a href="https://youtu.be/9m1MlaiuZB0" rel="nofollow noreferrer">https://youtu.be/9m1MlaiuZB0</a></p>
<p>On the video you can see that during the transition between tabs there is a strange flickering. This issue occures only when the animation of the transition goes from right to left.</p>
<p>The tabs are custom and implemented as a button-bar in the subheader.</p>
<pre><code>$scope.data.tabs = [
{
title: "Accepted",
state: "events.accepted"
},
{
title: "Pending",
state: "events.pending"
},
{
title: "Declined",
state: "events.declined"
}
];
<ion-view>
.....
<ion-header-bar align-title="center" class="bar bar-subheader event-type-bar">
<div class="button-bar">
<a class="button button-light event-type-bar-button" ng-repeat="tab in data.tabs" tab-state ui-sref="{{tab.state}}">
{{tab.title}}
</a>
</div>
</ion-header-bar>
<ion-nav-view name="events-view"></ion-nav-view>
.....
</ion-view>
</code></pre>
<p>Click on the tab changes the state and loads the new view.</p>
<p>This is my UI-router config for these tabs:</p>
<pre><code> .state('events', {
url: '/events',
abstract: true,
templateUrl: 'views/events/events.html',
controller: 'EventsCtrl'
})
.state('events.accepted', {
url: '/accepted',
views:{
'events-view':{
templateUrl: 'views/events/accepted.html',
controller: 'AcceptedEventsCtrl',
}
}
})
.state('events.pending', {
url: '/pending',
views: {
'events-view': {
templateUrl: 'views/events/pending.html',
controller: 'PendingEventsCtrl',
}
}
})
.state('events.declined', {
url: '/declined',
views: {
'events-view': {
templateUrl: 'views/events/declined.html',
controller: 'DeclinedEventsCtrl',
}
}
})
</code></pre>
<p>I tried to change the direction of the transition with <a href="http://ionicframework.com/docs/api/directive/navDirection/" rel="nofollow noreferrer">nav-direction</a>, but it doesn't help.</p>
<p>As a workaround I disabled the animation during the transitions between nav-views (from <a href="https://stackoverflow.com/questions/29098079/how-to-disable-change-animation-between-views-in-ion-nav-view">there</a>), but it's not the way which I'm looking for.</p>
<p>My ionic configuration:</p>
<ul>
<li>Cordova CLI: 5.3.3 </li>
<li>Ionic Version: 1.1.0 </li>
<li>Ionic CLI Version: 1.7.1</li>
</ul>
<p>By the way, the issue reproduces on the iOS device (iPhone 6) and simulator both, and also in the Chrome Device mode too.</p>

How to read multi-level json | <p>So, I know how to read a "single-level" json array. However, I can't figure out how to index the value I want from a multi-level json array.</p>
<p>I have this JSON data:</p>
<pre><code>{
"items": [
{
"snippet": {
"title": "YouTube Developers Live: Embedded Web Player Customization"
}
}
]
}
</code></pre>
<p>I would like to access the value of title, however neither of these access the value, but instead return undefined:</p>
<p><code>console.log(data["items"][0].title);</code></p>
<p>or:</p>
<p><code>console.log(data["items"][0]["title"]);</code></p>
<p>But, this code returns the <code>snippet</code> object:</p>
<p><code>console.log(data["items"][0]);</code></p>
<p>The <code>data</code> variable refers to the json data.</p>
<p>How should I go about this?</p> | 1 |

How to upload a json file with secret keys to Heroku | <p>I'm building a rails app that pulls data from Google Analytics using the Google Api Client Library for Ruby.</p>
<p>I'm using OAuth2 and can get everything working in development on a local machine. My issue is that the library uses a downloaded file, <code>client_secrets.json</code>, to store two secret keys.</p>
<p><strong>Problem:I'm using Heroku and need a way to get the file to their production servers.</strong> </p>
<p>I don't want to add this file to my github repo as the project is public. </p>
<p>If there is a way to temporarily add the file to git, push to Heroku, and remove from git that would be fine. My sense is that the keys will be in the commits and very hard to prevent from showing on github. </p>
<p><strong>Tried:</strong>
As far I can tell you cannot SCP a file to Heroku via a Bash console. I believe when doing this you get a new Dyno and anything you add would be only be temporary. I tried this but couldn't get SCP to work properly, so not 100% sure about this.</p>
<p><strong>Tried:</strong>
I looked at storing the JSON file in an Environment or Config Var, but couldn't get it to work. This seems like the best way to go if anyone has a thought. I often run into trouble when ruby converts JSON into a string or hash, so possibly I just need guidance here. </p>
<p><strong>Tried:</strong>
Additionally I've tried to figure out a way to just pull out the keys from the JSON file, put them into Config Vars, and add the JSON file to git. I can't figure out a way to put <code>ENV["KEY"]</code> in a JSON file though. </p>
<hr>
<p><strong>Example Code</strong>
The <a href="https://developers.google.com/api-client-library/ruby/auth/web-app" rel="noreferrer">Google library has a method</a> that loads the JSON file to create an authorization client. The client then fetches a token (or gives a authorization url).</p>
<pre><code>client_secrets = Google::APIClient::ClientSecrets.load('client_secrets.json')
auth_client = client_secrets.to_authorization
</code></pre>
<p>** note that the example on google page doesn't show a filename because it uses a default ENV Var thats been set to a path</p>
<p>I figure this would all be a lot easier if the <code>ClientSecrets.load()</code> method would just take JSON, a string or a hash which could go into a Config Var. </p>
<p>Unfortunately it always seems to want a file path. When I feed it JSON, a string or hash, it blows up. <a href="http://ar.zu.my/how-to-store-private-key-files-in-heroku/" rel="noreferrer">I've seen someone get around the issue with a p12 key here</a>, but I'm not sure how to replicate that in my situation. </p>
<p><strong>Haven't Tried:</strong>
My only other though (aside from moving to AWS) is to put the JSON file on AWS and have rails pull it when needed. I'm not sure if this can be done on the fly or if the file would need to be pulled down when the rails server boots up. Seems like too much work, but at this point I've spend a few hours on it so ready to attempt. </p>
<p>This is the specific controller I am working on:

Allowing for multiple modals in Vue.js | <p>Following the demo on the official site (<a href="http://vuejs.org/examples/modal.html" rel="nofollow">http://vuejs.org/examples/modal.html</a>)</p>
<p>I'm trying to set this up so that I can define multiple modal windows on a page, like this </p>
<p><a href="http://jsfiddle.net/m2sv4at5/" rel="nofollow">http://jsfiddle.net/m2sv4at5/</a></p>
<p>But since <code>modals['foo']</code> and <code>modals['bar']</code> aren't defined, Vue is throwing warnings that it's getting invalid types being sent into the prop. As soon as I initialize the script with <code>false</code> for both, it works, but that requires me to hard-code those modal names into the script, which is what I don't want.</p>
<p>In jQuery I would do this by defining a data target and simply making sure that matches an element with the right ID and a class of <code>modal</code>, but I'm unsure how to do something similar in Vue.</p> | 1 |

Kartik/Krajee Select2 not disabled | <p>Setting Select to to 'disabled' does not disable the element. The user can still click on the text of Select2 and the options box opens up. Here is a disabled control that was opened by clicking on the text and not the down-arrow button.</p>
<p><a href="https://i.stack.imgur.com/AYagr.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/AYagr.png" alt="Disabled Control:"></a></p>
<p>Here is my code:</p>
<pre><code><?= $form->field($model, 'billing_currency_id')->widget(Select2::className(), [
'data' => BillingCurrency::listIdCodes('','',true),
'disabled' => true,
'options' => ['disabled' => true,],
'pluginOptions'=>[
'allowClear'=>false,
'dropdownAutoWidth'=>true,
'disabled' => true,
], ]); ?>
</code></pre>
<p>Clicking on the down-arrow button keeps the control closed, but clicking on the text area of the control opens the options box.</p>

export array as Component prop using React | <p>I am wondering if there is a way to have an array of React elements in one file and then export that for import into another file with props? Something like...</p>
<pre><code>import MenuItem from 'material-ui/lib/menus/menu-item';
exports.menuItems = [
<MenuItem primaryText='Make glue' onTouchTap={this.props.makeGlue}/>, //<-- I am guessing props cannot be passed like this???
<MenuItem primaryText='Make more sticky glue'/>
]
</code></pre>
<p>... and then import menuItems into another file as a child of another component? I would like to keep various arrays of different menuIems in one file and import them into others as needed. Any thoughts or ideas? I untimately prefer to have server arrays of different menuItems exported from a single file if that's possible.</p>

Are there alternative UIs for Swagger files | <p>We are currently using <code>Postman</code> for building and testing our REST endpoints. There are some serious drawbacks in their product when it comes to sharing a collection. Basically you can't use source control for the document because it changes all the guids in json file when you import.</p>
<p>So we're looking at possibly switching to <code>Swagger</code>, the issue with Swagger is that <code>SwaggerUI</code> isn't very user friendly. We like that Postman gives you the ability to break up your collections into folders, and gives you a split screen where you can run a request and see the output.</p>
<p>Are there any third party tools which give a <code>Postman</code> style interface to <code>Swagger</code> files? i.e. easy to find a set of methods for a resource, and to make calls to it.</p> | 1 |
Web API 2 - Return Pdf, Show/Download Received Pdf File on Client (AngularJs) | <p>This is the code in my Web API 2 controller: </p>
<pre><code>//pdfBytes is a valid set of...pdfBytes, how it's generated is irrelevant
Byte[] pdfBytes = pdfConverter.GeneratePdf(myPdfString);
//using HttpResponseMessage instead of IHttpActionResult here because I read
//that the latter can cause problems in this scenario
var response = new HttpResponseMessage();
//Set reponse content to my PDF bytes
response.Content = new ByteArrayContent(pdfBytes);
//Specify content type as PDF - not sure if this is necessary
response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/pdf");
return response;
</code></pre>
<p>How do I trigger the browser to automatically download the PDF or open it in a new window once I have received the PDF on the client? (Note - I am not sure if byte array is the format I want to receive here).</p>
<pre><code>callToGetPdfFromDb()
.success(function (pdfFromWebApi) {
console.log('Got pdf...'');
//How do I show the received PDF to the user?

Vue.js limit selected checkboxes to 5 | <p>I need to limit number of selected checkboxes to 5.
I tried using :disabled like here:</p>
<pre><code> <ul>
<li v-for="item in providers">
<input type="checkbox"
value="{{item.id}}"
id="{{item.id}}"
v-model="selected_providers"
:disabled="limit_reached"
>
</li>
</ul>
</code></pre>
<p>And then:</p>
<pre><code>new Vue({
el: '#app',
computed:{
limit_reached: function(){
if(this.selected_providers.length > 5){
return true;
}
return false;
}
}
})
</code></pre>
<p>This kind of works, but when it reaches 5, all of the check boxes are disabled and you can't uncheck the ones you don't want.</p>
<p>I also tried to splice the array with timeout of 1 ms, which works but feels hacky.
Can anyone recommend anything please?</p> | 1 |

Creating a testing infrastructure with Pytest , Selenium Grid and Docker | <p>Based on this <a href="http://www.conductor.com/nightlight/running-selenium-grid-using-docker-compose/" rel="nofollow">article</a>, I successfully created the scalable selenium grid .
Then I want to run my test suites [written in Python] using Pytest into that Grid.</p>
<p>I am new to Docker and trying to find the best way to migrate my testing procedures into the microservices architecture. Essentially I want to give the ability to the devs to setup a full testing infrastructure locally on their PCs.</p>
<p>So, I have 4 <em>Dockerfiles</em> and 1 <em>docker-compose.yml</em> .</p>
<p>The BASE dockerfile:</p>
<pre><code>FROM ubuntu
ENV SEL_VERSION 2.44.0
# Update repos for Java
RUN apt-get update -qqy \
&& apt-get -qqy --no-install-recommends install \
software-properties-common \
&& rm -rf /var/lib/apt/lists/*
RUN add-apt-repository -y ppa:webupd8team/java
RUN echo debconf shared/accepted-oracle-license-v1-1 select true | debconf-set-selections
RUN echo debconf shared/accepted-oracle-license-v1-1 seen true | debconf-set-selections
# Install Java7
RUN apt-get update -qqy \
&& apt-get -qqy --no-install-recommends install \
oracle-java7-installer \
&& rm -rf /var/lib/apt/lists/*
# Download Selenium Server
RUN wget http://selenium-release.storage.googleapis.com/${SEL_VERSION%.*}/selenium-server-standalone-${SEL_VERSION}.jar
</code></pre>
<p>The HUB dockerfile :</p>
<pre><code>FROM org/grid:base
EXPOSE 4444
# Add and set permissions to the script that will launch the hub
ADD register-hub.sh /var/register-hub.sh
RUN chmod 755 /var/register-hub.sh
# start a shell and run the script
#WORKDIR /
CMD ["/bin/bash", "/var/register-hub.sh"]
</code></pre>
<p>The NODE dockerfile :</p>
<pre><code>FROM org/grid:base
# set the FF version to use
ENV FIREFOX_MINOR 34.0.5
# Update and install what's needed
RUN apt-get update -qqy \
&& apt-get -qqy --no-install-recommends install \
firefox \
xvfb \
bzip2 \
&& rm -rf /var/lib/apt/lists/*
# setup FF
RUN [ -e /usr/bin/firefox ] && rm /usr/bin/firefox
ADD https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/${FIREFOX_MINOR}/linux-x86_64/en-US/firefox-${FIREFOX_MINOR}.tar.bz2 /tmp/
RUN apt-get install -q -y libdbus-glib-1-2
RUN tar -xvjf /tmp/firefox-${FIREFOX_MINOR}.tar.bz2 -C /opt/
RUN chmod -R +x /opt/firefox/
RUN ln -s /opt/firefox/firefox /usr/bin/firefox
# add and set permissions for the bash script to register the node
ADD register-node.sh /var/register-node.sh
RUN chmod 755 /var/register-node.sh
# start a shell and run the script
CMD ["/bin/bash", "/var/register-node.sh"]
</code></pre>
<p>And the PYTEST dockerfile :</p>
<pre><code># Starting from base image
FROM ubuntu
# Set the Github personal token [to clone the QA code]
#todo------secret------
ENV GH_TOKEN some_token_some_token_some_token_
# Install Python & pip
RUN apt-get update
RUN apt-get upgrade -y
RUN apt-get install -y python python-pip python-dev && pip install --upgrade pip
# Install GIT
RUN apt-get update -y && apt-get install git -y
# [in the / folder] Create the folder and add the whole project from the repo to the container
RUN git clone https://$GH_TOKEN:[email protected]/org/org_QA.git /org_QA_folder
# Install dependencies via pip
WORKDIR /org_QA_folder
RUN pip install -r dependencies.txt
#
CMD /bin/bash
</code></pre>
<p>And the docker-compose file :</p>
<pre><code>hub:
image: org/grid:hub # image must already exist
ports:
- "4444:4444" # HOST:CONTAINER
external_links: # link to a container created outside of this YAML file
- pytest
volumes_from:
- pytest # must be created first
firefox:
image: org/grid:nodeff # image must already exist
links:
- hub
expose:
- "5555" # grid console open to public
</code></pre>
<p>So...I cannot understand how should I run something like "py.test /org_QA_folder/testcase.py" and run on the grid [essentially the node].</p>
<p>I first run the pytest container with
<code>docker run -dit -v /org_QA_folder --name pytest schoox/grid:py</code> and the other services with <code>docker-compose up -d</code> .</p>
<p>I tried multiple approaches:</p>
<ol>
<li><p>Not use a Pytest container but clone the code in the hub. But in this case , HUB container runs the hub of the grid [one CMD per container directive] . <strong>[EDIT: I chose the microservices architecture as Docker suggests]</strong></p></li>
<li><p>I leave the hub and node containers to run their specified services, and create a separate container [pytest] to send the tests from there. But the test wont run cause this container does not have xvfb.<strong>[EDIT: I just installed xvfb and worked]</strong> </p></li>
<li><p>I tried to use the pytest container as volume for the hub but remains the problem of running the tests from the hub container that already has a service running.<strong>[EDIT: For dev purposes I mount the code from the pytest container and use its console to test stuff on the other containers. After that I will use the pytest container to have the code separate]</strong></p></li>
</ol>
<p>Should I install all the packages ,that node container has, in the other containers? Ideally I want to use the pytest container console [to develop the infrastructure at least] to run the tests which will be sent to hub and run to many nodes.<strong>[EDIT: I didn't mingled with the hub and node, I just installed xvfb on pytest container]</strong></p>
<p>How would you suggest to do that? Am I missing something ? </p>
<p><strong>EDIT [steps towards solution]:</strong></p>
<p>I first start the pytest container [<code>docker run -dit -v /org/org_QA_folder --name pytest org/grid:py</code>] and then I run <code>docker-compose up -d</code> to launch the grid</p>
<p>In the compose file I use <code>external_links</code> and <code>volumes_from</code> for dev purposes. I wont work from inside any container when the setup is finished.</p>
<p>I changed the Pytest dockerfile and added this:</p>
<pre><code># Install xvfb [THAT WAS NEEDED!!!!!]
RUN apt-get install -y xvfb
</code></pre>
<p>I run one of my tests ,from inside the pytest container, to my already running Grid[on an EC2 instance] as a proof of concept and worked fine. It remains to send it to the dockerized grid. </p> | 1 |
How do I narrow down scope when running an ansible playbook? | <p>I have a playbook that takes a lot of time to execute, partly due to having a lot of nodes on which it has to run on (I am wasting time with ansible checking the status of all the nodes), and I need to make some changes somewhere in the middle of it.</p>
<p>What would be the best way in which I could narrow down the scope of the playbook? I've considered isolating the required change and/or just running the modified part on a single node?</p> | 1 |
TripleDESCryptoServiceProvider Specified key is not a valid size for this algorithm at 128 bytes? | <p>I'm trying to update my encrypt decrypt function from DES to TripleDES.
However, when I try to increase my key and iv byte array size from 8 to 128:</p>
<pre><code>byte[] key = new byte[128], iv = new byte[128];
TripleDESCryptoServiceProvider des = new TripleDESCryptoServiceProvider();
</code></pre>
<p>Where 8 was used for DESCryptoServiceProvider and 128 is now used for TripleDESCryptoServiceProvider I always get the same error:</p>
<pre><code>Specified key is not a valid size for this algorithm.
</code></pre>
<p>Even though my byte arrays are complete filled in.</p>
<p>What am I doing wrong? Is there any requirement besides the length to allow my key and iv to be used to create an Encryptor?</p> | 1 |

Has anyone successfully used Azure AD to authenticate users for a Node.js web application? | <p>I am attempting to use Azure Active Directory to authenticate users for my node.js web application, so far with no luck.</p>
<p>I am wondering if anyone has actually ever achieved it since the documentation is quite poor. There is typically example code, but not really any indication of what the required parameters are and what they should be.</p>
<p>I have tried passport-azure-ad (which I think is from Microsoft) and passport.azure-ad-oauth2 (which is from Auth0(?)). For passport-azure-ad, I have tried the BearerStrategy and also the OIDCStrategy with no luck.</p>
<p>For BearerStrategy I get some cryptic message about my client and resource identifying the same application, but since there is no documentation telling me what those should be, I'm at a loss.</p>
<p>For the OIDCStrategy, I'm a bit closer in that I get redirected to Microsoft for authentication, but on return I get the error "Error: ID Token not present in response". I'm guessing that my request isn't correct enough to give me a token back for whatever reason, but since there is no documentation...(you get the idea). </p>
<p>Anyway, if anyone has actually successfully achieved it and is able to share some pointers as to how it was achieved, that would be great.</p>
<p>Many thanks.</p> | 1 |

Make a CollectionViewCell bounce on highlight in Swift | <p>For the past couple of hours I have tried to accomplish the following:</p>
<p>In a UICollectionview when I highlight (touch down) a cell I want it to bounce inward a few pixels (to a smaller size) and on release bounce back to the original size.</p>
<p>Here is what I have tried so far:</p>
<pre><code>override func collectionView(collectionView: UICollectionView,
didHighlightItemAtIndexPath indexPath: NSIndexPath) {
collectionView.collectionViewLayout.invalidateLayout()
let cell = collectionView.cellForItemAtIndexPath(indexPath)
UIView.transitionWithView(cell!, duration: 1, options: UIViewAnimationOptions.CurveEaseIn, animations: {
let center = cell?.center
let frame2 = CGRect(x: 0, y: 0, width: 50, height: 50)
cell?.frame = frame2
cell?.center = center!
}, completion: nil)
}
</code></pre>
<p>(I have found much of this code example from this question:
<a href="https://stackoverflow.com/questions/13780153/uicollectionview-animate-cell-size-change-on-selection">UICollectionView: Animate cell size change on selection</a> but this is applied on cell selection. Not highlight.
)</p>
<p>So in the didHighlightItemAtIndexPath I set the highlighted cell to a new size. The size is set correct but the following problems arise:
1: it does not animate,
2: it moves to position (0,0) and animate back to center position. It should not move position at all - just the size.</p>
