Is it possible to register custom helpers in Ghost?
|
<p>I am using Ghost as an npm module following <a href="https://github.com/TryGhost/Ghost/wiki/Using-Ghost-as-an-npm-module" rel="nofollow noreferrer">this guide</a>.</p>
<p>I would like to add some custom helpers that I can leverage inside of my themes. Is there a way to do this without changing code inside the Ghost module?</p>
<p>This is my current code:</p>
<pre><code>const ghost = require('ghost');
const path = require('path');
const hbs = require('express-hbs');
const config = path.join(__dirname, 'config.js');
const coreHelpers = {};
coreHelpers.sd_nls = require('./sd_nls');
// Register a handlebars helper for themes
function registerThemeHelper(name, fn) {
hbs.registerHelper(name, fn);
}
registerThemeHelper('sd_nls', coreHelpers.sd_nls);
ghost({ config: config })
.then(ghostServer => ghostServer.start());
</code></pre>
<p>I think one possible problem is that my <code>hbs</code> is a new handlebars instance, not the same one used by Ghost, therefore when Ghost runs it doesn't include any helpers I've registered. </p>

Ghost items in javafx ListView with custom ListCell
|
<p>I try to view a custom object in a ListView using a custom ListCell. As an example to demonstrate the problem I chose <code>java.util.File</code>. Also for demonstration purpose I disable the ListCell directly when rendered. The items are added by an external process simulated by the thread. Everything looks nice until I apply the CSS coloring the disabled ListCell. Now it seems that there are some ghost items which get disabled together with the ListCell they are created of.</p>
<p>How can I solve this?</p>
<blockquote>
<p>App.java</p>

<pre><code>public class App extends Application

Search BindingList by property
|
<p>I have in my program a bindingList to which I want to add some elements. The elements are some instances of a class <strong>NameValue_Client</strong> which contains three properties. I want to search through the list using any property I want.</p>
<p>This is the class:</p>
<pre><code>Public Class NameValue_Client
Implements INotifyPropertyChanged
Public Event PropertyChanged(ByVal sender As Object, ByVal e As System.ComponentModel.PropertyChangedEventArgs) Implements System.ComponentModel.INotifyPropertyChanged.PropertyChanged
Private _assigned_db_name As String, _assigned_tcp_name As String
Private _val_obj As Client
Private _key_obj As Integer
Public WriteOnly Property DB_Name As String
Set(ByVal value As String)
_assigned_db_name = value
RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs("DB_Name"))
End Set
End Property
Public Property Value As Client
Get
Return _val_obj
End Get
Set(ByVal value As Client)
_val_obj = value
RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs("Value"))
End Set
End Property
Public Property Key As Integer
Get
Return _key_obj
End Get
Set(ByVal value As Integer)
_key_obj = value
RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs("Key"))
End Set
End Property
Public ReadOnly Property Name_Identifier As String
Get
Return String.Format("{0} : {1}", _assigned_db_name, _assigned_tcp_name)
End Get
End Property
Sub New(ByVal Key As Integer, ByVal DB_Name As String)
_assigned_db_name = DB_Name

End Sub
Private Sub changed(ByVal sender As Object, ByVal e As PropertyChangedEventArgs) Handles Me.PropertyChanged

End If
End Sub
Public Overrides Function ToString() As String

End Function
End Class

<p>I found this on <a href="https://msdn.microsoft.com/ro-ro/library/ms132695%28v=vs.100%29.aspx?f=255&MSPPError=-2147217396" rel="nofollow">MSDN</a> and it looks it's the solution but it only serches for one property and I don't want to put a select case . It has to be a better way. </p>
<p>This is the code I found:</p>
<pre><code>Public Class MyFontList
Inherits BindingList(Of Font)
Protected Overrides ReadOnly Property SupportsSearchingCore() As Boolean
Get
Return True
End Get
End Property
Protected Overrides Function FindCore(ByVal prop As PropertyDescriptor, _
ByVal key As Object) As Integer
' Ignore the prop value and search by family name.<--That's why
Dim i As Integer
While i < Count
If Items(i).FontFamily.Name.ToLower() = CStr(key).ToLower() Then
Return i
End If
i += 1
End While
Return -1
End Function
End Class
</code></pre>
<p>And I don't know how to implement this 'child' class (never worked with this type). </p>
<hr>
<p>This is my code(until now):</p>

InputTransparent=true does not work in Xamarin Forms Android
|
<p>From <a href="https://developer.xamarin.com/api/property/Xamarin.Forms.VisualElement.InputTransparent/" rel="noreferrer">this</a> link.</p>
<blockquote>
<p>false if the element should receive input; true if element should not receive input and should, instead, pass inputs to the element below. Default is false.</p>
</blockquote>
<p>What I want is, the Entry field must not be allowed to receive input from user. </p>
<p><code>InputTransparent=true</code> works well in iOS but doesn't work in Android, it still allows the user to give input.</p>
<p>I tried <code>IsEnabled=false</code> but that changes the look of my Entry field and I don't want that.</p>
<p>Is this some kind of bug?</p>

Dragula - Drag elements from one container to different elements

include gturri android xml rpc library in android project
|
<p>i need to include this library but i ve got several problems.
<a href="https://github.com/gturri/aXMLRPC" rel="nofollow">project library on github</a></p>
<p>i tried to follow the instructions on the github project but they did not work for me. I have to include the library in android studio. </p>
<p>i tried to:
1) copy the whole code in my project but i had a lot of conflicts about package, and, once solved, i began to have problems about lacks of functions not defined
2) i tried to use mvn install command, but it did not work, something like 100 errors displayed
3) i tried to open that project with intelliJ and then i tried to export jar file, but intelliJ told that it s an android project </p>
<p>does anyone have any idea about the procedure to include this library?
Thanks a lot in advance </p>

NLTK Relation Extraction - custom corpus in relextract.extract_rels
|
<p>I learnt that there is a built-in function in NLTK which could extract relations from NER-tagged sentences according the following:</p>
<pre><code> import re
IN = re.compile(r'.*\bin\b(?!\b.+ing\b)')
for fileid in ieer.fileids():
for doc in ieer.parsed_docs(fileid):
for rel in relextract.extract_rels('ORG', 'LOC', doc, corpus='ieer', pattern = IN):
print(relextract.rtuple(rel))
</code></pre>
<p>It seems me very promising for general purpose, but I understood that <code>relextract.extract_rels</code> accepts only <code>'ieer'</code> or <code>'conll2002'</code> for the parameter <code>corpus</code>. But in this case, its usage is restricted only to these two corpora, isn't it? How could one utilize it for his own corpus (presuming, of course, that it is NER-tagged).</p>

What happends when a perform_async is called but sidekiq is not running?
|
<p>I was wondering what happends when a perform_async is called on a worker but sidekiq (<code>bundle exec sidekiq</code>) isn't running ?</p>
<p>In my app I have some observers that ask sidekiq to do a job when one of my models is trigger (ie create, update or destroy in some cases).</p>
<p>I also have a rake task that builds me a database from some data I have.. When this task is running, it creates several records that trigger my observers who then push jobs in sidekiq queue.</p>
<p>For testing purpose I ran this task without turning on sidekiq and it's working fine, my data is being pushed in mysql !</p>
<p>I know ask myself what is happening to the job my observer tells my worker to do ? Is it still done ? Is it done but not asynchronously ? Is it <em>not</em> done ? </p>

Write from Serial Port to SD card
|
<p>I am trying to write from the Serial Port to an SD Card in my Arduino Mega 2560, using a card module.</p>
<p>I want to be able to write in a txt file what I type in the serial com.</p>
<pre><code>#include <SPI.h>
#include <SD.h>
const int chipSelect = 4;
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
Serial.print("This is a test and should be ignored");
if (!SD.begin(chipSelect)) {
Serial.println("\nCard failed, or not present");
// don't do anything more:
return;
}
else{
Serial.println("\ncard initialized.");
}
}
void loop() {
// put your main code here, to run repeatedly
File OpenFile = SD.open("test.txt", FILE_WRITE);
if(OpenFile and Serial.available());
{
OpenFile.println(Serial1.read());
OpenFile.close();
}
}
</code></pre>
<p>However a continous line of "-1" and "1", without the ", is written to the SD.</p>
<p>Yes, I am able to write to the SD card through other methods...</p>
<p>Cheers, PoP</p>

<p>I have a slide presentation with the same image on 10 of the 20 slides. When I rebuild with the presentation for another user I have to change those 10 slides to update the image.</p>
<p>Is there a way to have one of the images be the master image and all other link back to the master so I can update just the one image ? </p>

//foreach(var item in postTitles)

}
</code></pre>
<p>All the commented out sections are different things I have tried. Basically I get the dynamic <code>Json</code> data, but at this line <code>JObject rss = JObject.Parse(jsonData);</code> it fails. Goal is to get only the first 4 letters of the postcode attribute of each object in the <code>JArray</code>, save it in another <code>JArray</code> or <code>List</code> so I can use it for querying matching data from the database of the <code>MVC</code> web application.</p>

OneNote REST API - Downloading big attached file gives 502 Bad Gateway error
|
<p>I'm downloading (video) file attachments using the OneNote REST API with PHP and cURL. While all goes smoothly with files < 30.0 MB, anything larger produces a 502 Bad Gateway error and no data.</p>
<p>Whereas, in <a href="https://stackoverflow.com/questions/36733189/onenote-api-fails-to-get-any-notes-from-shared-notebook-for-sharing-user">a different situation</a> (shared notebook) with a 502 error the addition of "FavorDataRecency: true" to the API request solved the problem, in this situation it has no effect.</p>
<p>What's the way around (or through) this problem?</p>
<p>[<strong>EDIT</strong>]</p>
<p>It is a timeout problem (thanks Jim). My logs show that file downloads halt with the 502 error exactly at 120 seconds.</p>
<p>My PHP script is running on localhost under IIS 10 on Windows 10. I thought I was onto something when I found the connection timeout for IIS was 120 seconds. But I've upped it to 240 seconds and the timeout barrier is still there.</p>
<p>Other config changes I've made:</p>
<ul>
<li>Upped the FastCgi requestTimeout and activityTimeout in IIS 10.</li>
<li>Added a CURLOPT_TIMEOUT of 240 secs (as well as the CURLOPT_CONNECTTIMEOUT of 240 secs already set).</li>
</ul>
<p>Is there some other timeout setting I'm missing?</p>
<p>Any chance it could be a timeout on the OneNote servers?</p>

Find gaps between repeated numbers in an array
|
<p>I have an ArrayList with a list of numbers. Each number is always between 0 - 9. So the ArrayList contains numbers something as follows: </p>
<p>1 2 7 4 9 1 8 8 3 2 9 0 1 3 .... </p>
<p>I want to count the gaps before the number repeats again. For example the number 1 has a gap of 4 before repeating again. And then it goes on to have another gap of 6. I am looking to find out gaps up to 30. The list is long. I am looking to store and produce the following: </p>
<pre><code>Number 0 gap 1 : none
Number 0 gap 2: 5 times
Number 0 gap 3: 7 times
.....
Number 0 gap 30: none
Number 1 gap 1: 5 times
Number 1 gap 2: 3 times
......
Number 9 gap 30: 2 times
</code></pre>
<p>I really can't get my head around to how I could do this. I tried the following but it is clearly going nowhere. Looking for some direction and help please.</p>
<pre><code>//arr is the ArrayList
int gapCount = 0;
int[] gaps = new int[10];
for (int i = 0; i < arr.size(); i++) {
for (int j = 0; j < arr.size(); j++) {
if(arr.get(i) == arr.get(j)){
}
gapCount++;
}
}

In Pandas, generate DateTime index from Multi-Index with years and weeks
|
<p>I have a DataFrame <code>df</code> with columns <code>saledate</code> (in DateTime, dytpe <code><M8[ns]</code>) and <code>price</code> (dytpe <code>int64</code>), such if I plot them like</p>
<pre><code>fig, ax = plt.subplots()
ax.plot_date(dfp['saledate'],dfp['price']/1000.0,'.')
ax.set_xlabel('Date of sale')
ax.set_ylabel('Price (1,000 euros)')
</code></pre>
<p>I get a scatter plot which looks like below.</p>
<p><a href="https://i.stack.imgur.com/HNf63.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/HNf63.png" alt="enter image description here"></a></p>
<p>Since there are so many points that it is difficult to discern an average trend, I'd like to compute the average sale price per week, and plot that in the same plot. I've tried the following:</p>
<pre><code>dfp_week = dfp.groupby([dfp['saledate'].dt.year, dfp['saledate'].dt.week]).mean()
</code></pre>
<p>If I plot the resulting 'price' column like this</p>
<pre><code>plt.figure()
plt.plot(df_week['price'].values/1000.0)
plt.ylabel('Price (1,000 euros)')
</code></pre>
<p>I can more clearly discern an increasing trend (see below).</p>
<p><a href="https://i.stack.imgur.com/5l1EZ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5l1EZ.png" alt="enter image description here"></a></p>
<p>The problem is that I no longer have a time axis to plot this DataSeries in the same plot as the previous figure. The time axis starts like this:</p>
<pre><code> longitude_4pp postal_code_4pp price rooms \
saledate saledate
2014 1 4.873140 1067.5 206250.0 2.5
6 4.954779 1102.0 129000.0 3.0

43 4.938828 1019.0 549000.0 5.0
</code></pre>
<p>How could I convert this Multi-Index with years and weeks back to a single DateTime index that I can plot my per-week-averaged data against?</p>

Using Angular 2 Observable to display continuous stream of data
|
<p>I'm using a Couchbase Server as my database for my Angular 2 Web application. The data exchange happens through WebAPI's which talks to my CouchBase server.
I'm not sure if this is the correct way to do it yet at the moment I'm querying(polling) for the WebAPI every 5 seconds in order to get updated list of data</p>
<pre class="lang-javscript prettyprint-override"><code>this.events = getRecentEvents(_siteUrl: String) {
return Observable.interval(5000)
.switchMap(() => this.http.get(_siteUrl).map((res: Response) => res.json()))
.do(data => console.log('server data:', data)) // debug
.catch(this.handleError);
}
</code></pre>
<p>I'm using the Observable object returned from this call to bind it to a list on the UI using async pipes</p>
<pre class="lang-html prettyprint-override"><code><li class="item" *ngFor="#eventitem of events | async; #i = index">
<h1>{{eventitem}} {{i}}</h1>
</li>
</code></pre>
<p>The question I have is, Is this the right way to do?
Am I not putting too much load on the server with repetitive WebAPI calls?
Can any one suggest a better alternative if this is not the way to handle continuous flow of data.</p>

How can I convert an Unmanaged solution into Managed solution?
|
<p>I have a solution file (.zip) which contains an unmanaged solution from our supplier. </p>
<p>I also have an access of the instance of the supplier's CRM instance, but that instance doesn't show up the solution in the list as it is unmanaged one, and hence I am unable to export it.</p>
<p>It seems the supplier created the solution on other system, and exported it as unmanaged, and then imported that solution to the system on which he has provide access to me.</p>
<p>I want to import the solution to my target system but as a Managed solution.</p>
<p>Is there any possibility of doing so?</p>

Understanding the Storm Architecture
|
<p>I have been trying to understand the storm architecture, but I am not sure if I got this right. I'll try to explain as exactly as possible what I believe to be the case. Please explain what - if - I got wrong and what is right.</p>
<h2>Preliminary thoughts: <em>workers</em></h2>
<p><a href="http://storm.apache.org/releases/2.0.0-SNAPSHOT/Understanding-the-parallelism-of-a-Storm-topology.html" rel="nofollow">http://storm.apache.org/releases/2.0.0-SNAPSHOT/Understanding-the-parallelism-of-a-Storm-topology.html</a> suggests that a Worker is a process as does <a href="http://storm.apache.org/releases/2.0.0-SNAPSHOT/Concepts.html" rel="nofollow">http://storm.apache.org/releases/2.0.0-SNAPSHOT/Concepts.html</a> with "worker processes. Each worker process is a physical JVM", however <a href="http://storm.apache.org/releases/1.0.1/Setting-up-a-Storm-cluster.html" rel="nofollow">http://storm.apache.org/releases/1.0.1/Setting-up-a-Storm-cluster.html</a> states that a worker is a node with "Nimbus and worker machines". The website <a href="http://www.michael-noll.com/tutorials/running-multi-node-storm-cluster/" rel="nofollow">http://www.michael-noll.com/tutorials/running-multi-node-storm-cluster/</a> mentions "master node" and "worker nodes". So what: Is the worker a process or a physical node (or is a node a process)? Thus I think that there are two things: <em>Worker Nodes</em> and <em>Worker Processes</em>.</p>
<h2>What I believe to be true</h2>
<h3>Entities in play</h3>
<ul>
<li><em>Master Node</em> = Management Server</li>
<li><em>Worker Node</em> = <em>Slave Node</em></li>
<li><em>Nimbus</em> JVM process, running on <em>Master Node</em></li>
<li><em>ZooKeeper</em> JVM processes, running on <em>ZooKeeper Nodes</em></li>
<li><em>Supervisor</em> JVM process, running on <em>Worker Nodes</em></li>
<li><em>Worker Process</em> (JVM), running on <em>Worker Nodes</em></li>
<li><em>Executor</em> thread, run by <em>Worker Process</em></li>
<li><em>Task</em> (instances of <em>Bolts</em> and <em>Spouts</em>), executed by <em>Executor</em></li>
</ul>
<h3>How things work</h3>
<p>The <em>Nimbus</em> is a JVM process, running on the physical <em>Master Node</em>, that receives my program (<em>Storm topology</em>) takes the <em>Bolts and Spouts</em> and generates <em>tasks</em> from them. If a <em>Bolt</em> is supposed to be parallelized three times, the <em>Nimbus</em> generates three <em>tasks</em> for it. The <em>Nimbus</em> asks the <em>ZooKeeper</em> JVM processes about configurations of the cluster, e.g. where to run those <em>tasks</em> and the <em>ZooKeeper</em> JVM processes tells the <em>Nimbus</em>. In order to do this the <em>ZooKeeper</em> communicates with the <em>Supervisors</em> (what they are comes later). The <em>Nimbus</em> distributes the tasks then to the <em>Workers Nodes</em>, which are physical nodes. <em>Worker Nodes</em> are managed by <em>Supervisors</em>, which are JVM processes - exactly one <em>Supervisor</em> for one <em>Worker Node</em>. <em>Supervisors</em> manage (start, stop, etc.) the <em>Worker Processes</em>, which are JVM processes that run on the <em>Worker Nodes</em>. Each <em>Worker Node</em> can have multiple <em>Worker Processes</em> running. <em>Worker Processes</em> are JVM processes. They run one or multiple threads called <em>Executors</em>. Each <em>Executor Thread</em> runs one or multiple <em>Tasks</em>, meaning one or multiple instances of a <em>Bolt</em> or <em>Spout</em>, <a href="http://storm.apache.org/releases/2.0.0-SNAPSHOT/Understanding-the-parallelism-of-a-Storm-topology.html" rel="nofollow">but those have to be of the same <em>Bolt</em></a>. </p>
<p>If this is all true, it begs the questions:</p>
<ul>
<li>What is the point of having multiple <em>Worker Processes</em> run on one <em>Worker Node</em> - after all a process can use multiple processor cores, right?</li>
<li>What is the point of having multiple <em>Tasks</em> run by one <em>Executor</em> thread if they have to be of the same <em>Bolt</em>/<em>Spout</em>? A thread is only run on one processor core, so the multiple <em>Bolt</em>/<em>Spout</em> have to run after each other and can not be parallelized. Running indefinitely in the Storm topology - what would be the point having two instances of the same <em>Bolt</em>/<em>Spout</em> in a <em>Exectuor</em> thread?</li>
</ul>

OpenCl maximum work-items per compute unit
|
<p>I am writing an <code>OpenCL</code> code to find an optimum work-group size to have maximum occupancy on GPU. For this, I want a function that returns the maximum number of work-items per compute unit.</p>
<p>Basically, I am deriving this from a <code>CUDA</code> code and I want an equivalent of <code>maxThreadsPerMultiProcessor</code>.
In CUDA these were the values returned on device query:
Maximum number of threads per multiprocessor: 2048
Maximum number of threads per block: 1024</p>
<p>In OpenCL:
CL_DEVICE_MAX_WORK_GROUP_SIZE: 1024</p>
<p>In CUDA it doesn't asks for kernel info to return this value.
I need an equivalent function for OpenCL.
Thanks in advance.</p>

Fluent-ffmpeg and complex filter in Electron (node)
|
<p>I want to use fluent-ffmpeg module to call ffmpeg with complex filter from Electron but have no success. The error '[AVFilterGraph @ 0xb8.......] No such filter " Error initalizing complex filters . Invalid argument' is the same as in this question <a href="https://stackoverflow.com/questions/37828262/error-running-ffmpeg-command-in-android-splitting-command-in-array-not-workin">Error : Running FFmpeg command in Android ,splitting command in array not working</a> but the context is different.</p>
<p><strong>What is needed?</strong>
Run this ffmpeg command using fluent-ffmpeg:</p>
<blockquote>
<p>ffmpeg -i safework-background-0.mp4 -i image1.png -i image2.png -i
image3.png -filter_complex "[0:v][1:v]
overlay=1:1:enable='between(t,5,8.5)' [tmp]; [tmp][2:v]
overlay=1:1:enable='between(t,8.5,12)' [tmp]; [tmp][3:v]
overlay=1:1:enable='between(t,12,15)'" test-video-safework3.mp4</p>
</blockquote>
<p>It uses a complex filter to overlay three images on a video in sequence and exports a new video.</p>
<p><strong>What doesn't work?</strong>
Obviously fluent-ffmpeg chokes with required quotes for complex filter, that is my conclusion (and is the same as for the Android variant question above).</p>
<p><strong>What works without fluent-ffmpeg in Electron?</strong>
As you can guess I have to resort to calling ffmpeg directly. To help others, the following command, with input and output video filenames parametrized, translates to Electron as:</p>
<pre><code> var spawn = require('child_process').spawn
var fargs = ['-y', '-i', sourceDir.path() + '/' + inVideoName, '-i', tempDir.path() + '/' + 'image1.png',
'-i', tempDir.path() + '/' + 'image2.png', '-i', tempDir.path() + '/' + 'image3.png',
'-filter_complex', '[0:v][1:v]overlay=1:1:enable=\'between(t,5,8.5)\'[tmp];' +
'[tmp][2:v]overlay=1:1:enable=\'between(t,8.5,12)\'[tmp];[tmp][3:v]' +
'overlay=1:1:enable=\'between(t,12,15)\'', targetDir.path() + '/' + outVideoName]
var ffmpeg = spawn(ffmpegc, fargs, { cwd:jetpack.cwd(app.getPath('home')).path() })
// some code ommitted
ffmpeg.on('close', (code) => {
console.log(`child process exited with code ${code}`)
webContents.send('notify-user-reply', 'Video processing done.')
})
</code></pre>
<p>The above command already has removed spaces between various filters (in complex filter) for each image or it would also choke.</p>
<p>I would really love to use fluent-ffmpeg in Electron, not just for the convenience of calling ffmpeg more elegantly but also for some additional features like easy progress reporting. </p>

Foundation 6 Mega Menu and Responsive Toggle Navigation with Drilldown Title Bar on Small
|
<p>I want to create a full-width dropdown mega menu that I can also combine with a top bar that has an drilldown menu in mobile screens. Any method I've tried on Foundation only works with Foundation 5, since they changed top bar in Foundation 6. </p>
<p>So far, (with the help from this thread: <a href="http://foundation.zurb.com/forum/posts/36800-f6-and-mega-menus" rel="nofollow">http://foundation.zurb.com/forum/posts/36800-f6-and-mega-menus</a>) I have been able to create the dropdown mega menu and on small screens, the title bar appears and toggles open. However, when I try to open an item with a drilldown submenu, it still treats it as though it is a dropdown item.</p>
<p>Also, I am noticing that full-width hover for the submenus are somehow pushing the screen to a lot of extra empty space horizontally. While I can get rid of the extra empty horizontal space by adding a max-width:100% to the dropdown-pane class, the second of my two mega submenus doesn't display full-width correctly when I hover over them. Although in the codepen, they show just fine.</p>

How do I make this pure CSS image comparison slider start at the middle?
|
<p>I have the following </p>
<p><a href="http://codepen.io/anon/pen/AXrEzK" rel="nofollow">http://codepen.io/anon/pen/AXrEzK</a></p>
<p>I want the slider to start in the middle instead of starting way at the left. I have tried to edit the width and make it 185px, but the problem with that is it ruins the slider, the slider starts at the middle but no longer slides to the left.</p>
<pre><code>.image-slider > div {
position: absolute;
top: 0; bottom: 0; left: 0;
width: 185px;
max-width: 100%;
overflow: hidden;
resize: horizontal;

How are Arrows and Functions different in haskell?
|
<p>I learned and searched about Arrows for a while, and I'm a bit confused about necessity of Arrow class.
As I know, Arrow class is abstraction of function, and Arrow <code>A a b c</code> represents something takes input of type b and output of type c. Also, it provides several fundamental operations like <code>>>></code>, <code>arr</code>, and <code>first</code>.</p>
<p>However, I can't find any difference between standard function of type <code>b -> c</code> and Arrow of type <code>A a b c</code>. In my view, <code>first</code> and <code>>>></code> can be replaced by <code>\(b, c) -> (f b, c)</code>, and <code>(.)</code>. Also, since every computation inside arrow are represented by function, if we replace arrows by those function, I think there will be no difference.</p>
<p>In short, I think every node of computation graph of Arrows(something like in <a href="https://www.haskell.org/arrows/syntax.html" rel="noreferrer">https://www.haskell.org/arrows/syntax.html</a>) can be replaced by standard function of Haskell. If it is true, why do we use Arrow instead of functions?</p>

Angular 2, localhost/null error when trying to use http.get?
|
<p>I am using Angular 2 to make a webpage. When I load the page, I use OnInit to run the following method (with generic names substituted):</p>
<pre><code>getAllObjects(): Promise<object[]>{
return this.http.get(this.getAllObjectsUrl).toPromise().then(response => response.json().data).catch(this.handleError);
}
</code></pre>
<p>I've verified in my browser that the getAllObjects url does indeed return an array of <code>object</code> in JSON format. Here is the url if it is helpful:</p>
<pre><code>private getAllObjectsUrl : 'http://99.240.124.235:7060/REST/rest/companyService/getAllCompanies.json/';
</code></pre>
<p>However, this method triggers the handleError catch and the browser's debugging log shows <code>GET localhost:3000/null 404 NOT FOUND</code> (I am using an npm server to run it, hence the localhost).</p>
<p>I do not believe it is a CORS issue because I downloaded the Chrome CORS plugin and other API calls have worked. It is only this particular API url that is causing a problem, which I find strange as my other API calls work and they follow the exact same format (except a different url). </p>
<p>I thought maybe the <code>appComponent</code> wasn't allowed an OnInit, but I replaced <code>getAllObjects()</code> with a different working API call, and I didn't receive this error.</p>
<p>I am completely stuck and any help would be appreciated (could this error be because of the web API, not the front end?).</p>

Sql query join average of one column where another column is between two columns values of another table
|
<p>I have two tables, one has two columns that have dates. The other has one column with dates and another with numeric data. I would like to join the average of the second table's numeric column values where its date column is in between the values of the two date columns in the first table. Something like the following:</p>
<p>Table1:</p>
<pre><code>Date1 Date2
6/28 2:00 6/30 4:00
7/1 4:00 7/4 7:00
...
</code></pre>
<p>Table2:</p>
<pre><code>Date3 Value
6/29 1:00 6.5
6/30 3:00 2.5
7/1 5:00 3.0
7/3 9:00 5.0
...
</code></pre>
<p>FinalTable:</p>
<pre><code>Date1 Date2 AvgValue
6/28 2:00 6/30 4:00 4.5
7/1 4:00 7/4 7:00 4.0

Why member variables of a const object are not const
|
<p>Just asked a similar question which boils down to this one. </p>
<pre><code>#include <iostream>
using namespace std;
struct A {
A() : a{1} {};
int a;
};
template <typename Which>
struct WhichType;
int main() {
const A a;
const A& a_ref = a;
const A* a_ptr = &a;
WhichType<decltype(a.a)> which_obj; // template evaluates to int
WhichType<decltype(a_ref.a)> which_ref; // template evaluates to int
WhichType<decltype(a_ptr->a)> which_ptr; // template evaluates to int
return 0;
}
</code></pre>
<p>Why do the templates do not become <code>const int</code> instead of <code>int</code>?</p>

Requiring only one of two dependencies in a requirements file
|
<p>Some Python packages require one of two packages as a dependency. For example, <code>Ghost.py</code> requires either <code>PySide</code> or <code>PyQt4</code>.</p>
<p>Is it possible to include such a dependency in a <code>requirements.txt</code> file? Is there any 'or' operator that works with these files?</p>
<p>If not, what can I do to add these requirements to the file so only one of them will be installed?</p>

Test offline browsing with Android Chrome
|
<p>I am trying to build an offline-data persistent web application with Service Workers. I managed to have it working on my laptop Chrome (51) and it loads the cached files and displays an offline message when I simulate being offline via the Chrome DevTools - Network tab.
I uploaded the application to github to make sure it is available with https (<a href="https://mguardos.github.io/index.html" rel="nofollow">https://mguardos.github.io/index.html</a>)</p>
<p>However, when I try to test it with my Android Chrome (Nexus 5 - Android 6.0.1 - Chrome 51), the application loads fine when online, but if I set the plane mode on and reload the page, the browsers is not checking the service worker but displaying the offline message directly</p>
<p>"You are offline.
Your devide is offline.
Try: ...
ERR_INTERNET_DISCONNECTED"</p>
<p>Is there any option that I have to enabled in my Android Chrome for Service workers to work?</p>
<p>Thanks for any tip</p>
<p>PS (edited): Same issue occurs with Opera 37 on Android 6.0.1. However, the Registration service happens properly for both Chrome and Opera in the background (validated via an alert upon the registration method is successfully completed)</p>
<p>PSS: The link above tries to be a very basic example of combining service workers with AppCache, to retrieve localStorage and IndexedDB data so any constructive critic would be very much appreciated on top of the original question</p>

React Immutable JS updateIn with list key in object
|
<p>I have an immutable state in React, where I have an map containing list elements. </p>
<p>My getIn function works correctly, e.g.:</p>
<pre><code>console.log(this.state.settings.getIn(["airlines"])[index].checked);
</code></pre>
<p>But I want to update this value with the reverse. </p>
<p>Reading the docs of immutable JS, it should be something like this, but due to my index key I can't get it to work, since my update val should be within the ().</p>
<p>What I currently have is something like this:</p>
<pre><code>this.state.settings.updateIn((["airlines"])[index].checked, val => !val);
</code></pre>
<p>Any help is appreciated!</p>

<p>So i am starting to learn scenekit and i have some models i want to try on the iphone simulator so i just changed </p>
<pre><code>let scene = SCNScene(named: "art.scassets/ship.scn")!
</code></pre>
<p>which works fine in the scenekit default file to</p>
<pre><code>let scene = SCNScene(named: "art.scassets/battleship.scn")!
</code></pre>
<p>which is a 3d model of a battleship but when i run it it gives me an error near a line of code:</p>
<pre><code>let ship = scene.rootNode.childNodeWithName("ship", recursively: true)!
</code></pre>
<p>The error says: Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP,subcode=0x0)
And: fatal error: unexpectedly found nil while unwrapping an Optional value (lldb)</p>
<p>I'm sorry but it is very hard to explain, but if anyone understood what i said please tell me how to import 3d models to scenekit, i haven't found any tutorial that shows how to do that custom 3d models to scenekit</p>

Webpack can't parse fontello fonts
|
<p>I'm using a custom icon font, made with fontello.
When trying to use this in webpack, I get the following error:</p>
<pre><code>ERROR in ./src/assets/fonts/fontello/fontello.ttf?86736756
Module parse failed:

character '' (1:0)
You may need an appropriate loader to handle this file type.
SyntaxError: Unexpected character '' (1:0)
</code></pre>
<p>And it does this for woff(2), ttf, svg... all of them.
I've used several solutions found on SOF, but none of them seem to work. </p>
<p>This is my webpack.config.js:</p>
<pre><code>module: {
loaders: [
{ test: /\.js$/, loader: 'babel', exclude: /node_modules/},
{ test: /\.css$/, loader: "style!css!" },
{ test: /\.scss$/, loader: "style!css!sass!" },
{ test: /\.(woff|woff2)(\?v=\d+\.\d+\.\d+)?$/, loader: 'url?limit=10000&mimetype=application/font-woff'},
{ test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/, loader: 'url?limit=10000&mimetype=application/octet-stream'},
{ test: /\.eot(\?v=\d+\.\d+\.\d+)?$/, loader: 'file'},
{ test: /\.svg(\?v=\d+\.\d+\.\d+)?$/, loader: 'url?limit=10000&mimetype=image/svg+xml'},
]
}
</code></pre>
<p>Anyone got any ideas on this one?</p>
<p>Thanks!</p>

JQuery plugin not working when used multiple times in a page
|
<p>I am trying to write a JQuery plugin called grid2carousel which takes some content in a Bootstrap-style grid on desktop devices and becomes a carousel on smaller screens.</p>
<p>The plugin works fine if it is the only instance of it on a page but runs into some problems if there are more than one. I have created a Codepen here to demonstrate the issue:</p>
<p><a href="http://codepen.io/decodedcreative/pen/BzdBpb">http://codepen.io/decodedcreative/pen/BzdBpb</a></p>
<p>Try commenting out one of the components in the HTML section of the codepen, resizing the browser til it becomes a carousel, and then repeating this process again with it uncommented</p>
<p>The plugin works by running an internal function called SetupPlugin every time the browser width is below a breakpoint specified in a data attribute in the HTML. If the browser width exceeds this breakpoint a function called DestroyPlugin reverts the HTML back to its original state. Like so:</p>
<pre><code> checkDeviceState = function(){
if($(window).width()>breakpointValue){
destroyPlugin();
}else{
if(!$element.hasClass('loaded')){
setupPlugin();
}
}
},
</code></pre>
<p>Below is my plugin code in its entirety. Could someone give me a pointer as to what I'm doing wrong here?</p>
<pre><code>(function (window, $){
$.grid2Carousel = function (node, options){
var
options = $.extend({slidesSelector: '.g2c-slides', buttonsSelector: '.g2c-controls .arrow'}, {},options),

}
setupPlugin = function(){
// Add loaded CSS class to parent element which adds styles to turn grid layout into carousel layout
$element.addClass("loaded");
// Get the height of the tallest child element
elementHeight = getTallestInCollection($slides)
// As the carousel slides are stacked on top of each other with absolute positioning, the carousel doesn't have a height. Set its height using JS to the height of the tallest item;

Bootstrap grid putting images on top of each other

<p>I'm having issues getting the 3 images to appear next to each other. I'm using ng-repeat with angular to output the first 3 images, but they are on top of each other no matter how I mess with the grid's col-md size. Any suggestions on how to get the images next to each other.</p>

How to use the beforeEach in node-tap?
|
<p>Can someone provide an example on how to use the <code>beforeEach</code>? <a href="http://www.node-tap.org/api/" rel="nofollow">http://www.node-tap.org/api/</a>
Ideally, an example of the promise version, but a callback version example would also be nice. </p>
<p>Here is a test I created which works fine:</p>
<pre><code>'use strict';
const t = require('tap');
const tp = require('tapromise');
const app = require('../../../server/server');
const Team = app.models.Team;
t.test('crupdate', t => {
t = tp(t);
const existingId = '123';
const existingData = {externalId: existingId, botId: 'b123'};
const existingTeam = Team.create(existingData);
return existingTeam.then(() => {
stubCreate();
const newId = 'not 123'
const newData = {externalId: newId, whatever: 'value'};
const newResult = Team.crupdate({externalId: newId}, newData);
const existingResult = Team.crupdate({externalId: existingId}, existingData);
return Promise.all([
t.equal(newResult, newData, 'Creates new Team when the external ID is different'),
t.match(existingResult, existingTeam, 'Finds existing Team when the external ID exists')
]);
});
})
.then(() => {
process.exit();
})
.catch(t.threw);
function stubCreate() {
Team.create = data => Promise.resolve(data);
}
</code></pre>
<p>Before I do anything, I want to persist <code>existingTeam</code>. After it's saved, I want to stub <code>Team.create</code>. After these two things, I want to start actually testing. I think it would be cleaner if instead of using a <code>Promise.all</code> or perhaps duplicating the test code, I could use <code>beforeEach</code>.</p>
<p>How would I convert this to use <code>beforeEach</code>? Or what is an example of its usage?</p>

FreeRTOS suspend task from another function
|
<p>So I have a half duplex bus driver, where I send something and then always have to wait a lot of time to get a response. During this wait time I want the processor to do something valuable, so I'm thinking about using FreeRTOS and vTaskDelay() or something. </p>
<p>One way to do it would off be splitting the driver up in some send/receive part. After sending, it returns to the caller. The caller then suspends, and does the reception part after a certain period of time. </p>
<p>But, the level of abstraction would be finer if it continues to be one task from the user point of view, as today. Therefore I was thinking, is it possible for a function within a task to suspend the task itself? Like</p>
<pre><code> void someTask()
{
while(true){
someFunction(&someTask(), arg 1, arg 2,...);
otherStuff();
}
}
void someFunction(*someSortOfReferenceToWhateverTaskWhoCalled, arg1, arg2 ...)
{
if(something)
{
/*Use the pointer or whatever to suspend the task that called this function*/
}
}

Selecting only rows where one date is less than another with Pandas Dataframe

<p>I have a pandas dataframe with this data:</p>
<pre><code>Id Converteddate Createddate

00138000015me56AAA 2015-10-22 00:00:00 2015-10-22 22:17:52
</code></pre>
<p>I'm trying to only keep rows where ConvertedDate <= CreatedDate + 3 days, so I converted both strings to datetime, then used timedelta to calculate the 3 days. I don't get any error codes, but my output dataframe is keeping records that don't meet my criteria of ConvertedDate <= CreatedDate + 3 days.</p>
<pre><code>netnewframe['CreatedDate'] = netnewframe.apply(lambda row: ToDateTimeObj(row['CreatedDate']), axis=1)
netnewframe['ConvertedDate'] = netnewframe.apply(lambda row: ToDateTimeObj(row['ConvertedDate']), axis=1)
netnewframe = netnewframe[(netnewframe.ConvertedDate <= (netnewframe.CreatedDate + timedelta(days=3)))]

Elevation/Shadow to a dialog for pre-21 or pre-lollipop
|
<p>There are posts related to elevation for views for pre-lollipop devices. I applied techniques that could be applied to the dialog but I still can not have elevation/shadow to my dialog. </p>
<p>I tried this in the style but it did not work.</p>
<pre><code><item name="android:background">@android:drawable/dialog_holo_light_frame</item>
</code></pre>
<p>ViewCompat.setElevation() and View.setOutLineProvider() methods are available from Lollipop. So can not use them. </p>
<p>I am not able to add the screeshots here for unknown reason. But the dialog is flat on KK and is elevated and look nice on Lollipop. </p>
<p>This is how I created dialog: </p>
<pre><code>AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(context, R.style.AlertDialogStyle));
Dialog dialog = builder.create();
</code></pre>
<p>And AlertDialogStyle is just this: </p>
<pre><code><style name="AlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
</style>
</code></pre>
<p>Can you help me with any clue on how can I add elevation to dialog on pre-lollipop or pre-21 devices ?</p>

Is every method of ServerEndpoint executed by different thread?
|
<p>I use GF 4 as JavaEE server. </p>
<p>This is how I understand servlet processing: There is a pool of threads and when request comes one thread from this pool is taken to process the request. After that the thread is put back to pool.</p>
<p>Based on the information above I suppose (I am not sure) that websockets (server end points) are processed this way: There is pool of threads, when</p>
<ul>
<li>Client creates new websocket a thread is taken from pool to create new instance of ServerEndpoint and to execute @OnOpen method. After that thread is put back to pool.</li>
<li>Client sends message over websocket to server. Thread is taken from pool to execute @OnMessage method. After that thread is put back to pool.</li>
<li>Client closes the websocket - thread is taken from pool to execute @OnClose method. After that thread is put back to pool.</li>
</ul>
<p>It all means that every method of ServerEndpoint can be executed by different threads. Is my understanding right?</p>

Highlight Table Row Based On Column Value Equal To Value In Another Table Column
|
<p>I have two tables, <code>tblPO</code> in sheet <code>Purchase Order</code> and <code>tblRiskItems</code> in sheet <code>Risky Items</code>. <code>tblPO</code> is used for the purchase order that has columns <code>Item #</code>, <code>Description</code>, <code>Unit Price</code> and <code>Line Total</code>. <code>tblRiskItems</code> contains a list of our items that are either fast movers, slow movers or obsolete, having columns <code>Item #</code>, <code>Description</code> and <code>Status</code> (this column showing whether an item is fast or slow moving or obsolete). Below are pictures of my tables:</p>
<h3>tblPO</h3>
<p><a href="https://i.stack.imgur.com/T60xo.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/T60xo.jpg" alt="tblPO"></a></p>
<h3>tblRiskItems</h3>
<p><a href="https://i.stack.imgur.com/5Ygr9.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5Ygr9.jpg" alt="tblRiskItems"></a></p>
<p>What I need is to higlight the entire row in <code>tblPO</code> where it’s <code>Item #</code> matches <code>tblRiskItems</code>’ <code>Item #</code> so that the user knows ordering that item is a risk and needs to be followed up. It would also be great to format the row based on the value in column <code>Status</code> of <code>tblRiskItems</code>, for e.g. green if item is fast moving, yellow if item is slow moving and red if item is obsolete.</p>
<p>My efforts with Conditional Formatting has ended in a disaster. If anyone can suggest how I will be able to achieve this it would be greatly appreciated!</p>

Using RNN in R with factorial input variables
|
<p>In <a href="https://cran.r-project.org/package=rnn" rel="nofollow"><code>rnn</code></a> package in R, the example shows how to train a RNN with numeric input variables.</p>
<p>The example code is:</p>
<pre><code>library('rnn')
# create training numbers
set.seed(1)
X1 = sample(0:127, 7000, replace=TRUE)
X2 = sample(0:127, 7000, replace=TRUE)
# create training response numbers
Y <- X1 + X2
# convert to binary
X1 <- int2bin(X1, length=8)
X2 <- int2bin(X2, length=8)
Y <- int2bin(Y, length=8)
# create 3d array: dim 1: samples; dim 2: time; dim 3: variables
X <- array( c(X1,X2), dim=c(dim(X1),2) )
# train the model
model <- trainr(Y=Y,
X=X,
learningrate = 0.1,
hidden_dim = 10,
start_from_end = TRUE )
</code></pre>
<p>In the above example, <code>X1</code> and <code>X2</code> are numerical variables.</p>
<p>How can I train a RNN model in R if the input variables are factor?</p>
<p>Thanks a lot,</p>

getInboxThreads() for specific inbox folder. Google Apps Script gmail
|
<p>I am trying to retrieve email threads from only a specific folder which I named 'Approval_needed'. I have found a way to get all of my inbox threads like so from the <a href="https://developers.google.com/apps-script/reference/gmail/gmail-app#getInboxThreads()" rel="nofollow">Google Apps Script Reference page</a>:</p>
<pre><code>var threads = GmailApp.getInboxThreads();
for (var i = 0; i < threads.length; i++) {
Logger.log(threads[i].getFirstMessageSubject());
}
</code></pre>
<p>Is it possible to do something like <code>getInboxThreads for folder 'Approval_needed'</code>?<br />
I have searched around and have not found an answer for this. I have found other methods such as <code>getPriorityInboxThreads()</code> and <code>getStarredInboxThreads()</code>, but nothing like <code>getInboxThreads(string)</code>.</p>

Moq verify uses objects modified in Returns, rather than what was actually passed in
|
<p><strong>Background</strong></p>
<p>I have a class that uses NHibernate to persist objects to a database. When you call <code>MergeEntity</code> for an object that does not have an ID set, NHibernate populates that object with an ID when it is returned. In order to make sure I always use the same object as NHibernate is using, I pass that updated object back from my "<code>Save</code>" function.</p>
<p><strong>Problem</strong></p>
<p>I am trying to mock that same behavior using Moq, which is usually very intuitive and easy to use; however, I am having some trouble verifying that the calls to <code>Save()</code> are being made with the correct arguments. I would like to verify that the ID of the object being passed in is zero, then that it is set properly by the <code>Save</code> function. Unfortunately, when I modify the ID in the <code>Moq.Returns()</code> function, the <code>Moq.Verify</code> function uses the modified value rather than the value of the ID that was passed in.</p>
<p>To illustrate, here is a very basic class (I override the ToString() function so my test output will show me what ID was used when the mocked Save() is called):</p>
<pre><code>public class Class1
{
private readonly IPersistence _persistence;
/// <summary>Initializes a new instance of the <see cref="T:System.Object" /> class.</summary>
public Class1(IPersistence persistence)
{
_persistence = persistence;
}
public int Id { get; set; }
public void Save()
{
_persistence.Save(this);
}
public override string ToString()
{
return Id.ToString();
}
}
</code></pre>
<p>Here is the Interface (very straight forward):</p>
<pre><code>public interface IPersistence
{
Class1 Save(Class1 one);
}
</code></pre>
<p>And here is the test that I think should pass:</p>
<pre><code>[TestFixture]
public class Class1Tests
{
[Test]
public void Save_NewObjects_IdsUpdated()
{
var mock = new Mock<IPersistence>();
mock.Setup(x => x.Save(It.IsAny<Class1>()))
.Returns((Class1 c) =>
{
// If it is a new object, then update the ID
if (c.Id == 0) c.Id = 1;
return c;
});
// Verify that the IDs are updated for new objects when saved
var one = new Class1(mock.Object);
Assert.AreEqual(0, one.Id);
one.Save();
mock.Verify(x => x.Save(It.Is<Class1>(o => o.Id == 0)));
}
}
</code></pre>
<p>Unfortunately, it fails saying that it was never called with arguments that match that criteria. The only invocation to <code>Save</code> that was made on the mock is with an object that had an ID of 1. I have verified that the objects have an ID of 0 when they enter the Returns function. Is there no way for me to distinguish what was passed into the mock from what those objects are updated to be if I update the values in my <code>Returns()</code> function?</p>

How can I do a POST redirect from the process_payment function in a woocommerce custom payment gateway?
|
<p>I wish to do a redirect from the process_payment in my custom payment gateway for Wordpress/Woocommerce. </p>
<p>To do a GET redirect you would do:</p>
<pre><code>function process_payment( $order_id ) {
//some code here
//CPN is a value entered by user from custom payment field
$cpn = $_POST['cpn'];
return array(
'result' => 'success',
'redirect' => 'https://www.sandbox.bankserver.com/cgi-bin/webscr?test_ipn=1&CPN='. $cpn
);
}
</code></pre>
<p>The values received from the user in custom payment fields are security sensitive so the bank does not want to receive them via GET. How can I do a POST? </p>
<p>I will POST to the bank URI...which will allow the user to enter CVV on the bank page and then redirect back to my Wordpress site.</p>

R Plotly: Smaller markers in bubble plot
|
<p>I'm making a bubble plot in Plotly (for R) and I keep getting overlapping markers. Is there a way to "scale down" all markers, so that their relative sizes are preserved but there is no overlap? I want to keep the dimensions of plot the same. Here's a test case:</p>
<pre><code>test <- data.frame(matrix(NA, ncol=3, nrow=14))
colnames(test) <- c("Group", "Numbers", "Days")
loop<- 1
for(i in 1:7){
test[i,] <- c(1, i, loop)
loop <- loop * 1.5
}
loop <- 1
for(i in 1:7){
test[i+7,] <- c(2, i, loop)
loop <- loop * 1.3
}
plot_ly(test, x=Group, y=Numbers, size=Days, mode="markers")
</code></pre>

angular 2 - cache http get result
|
<p>I have a LanguageService that provides a list of available languages.
This list needs to initialized by a backend request:</p>
<pre><code>getAvailableLanguages(): Observable<Language[]> {
...
return this.http.get(ApiResources.LANGUAGE, requestOptions)
.map(response => this.extractJson(response))
.catch(error => this.handleError(error));
}
</code></pre>
<p>I would like to avoid requesting the backend each time another service calls <code>languageService.getAvailableLangauges()</code>.</p>
<p>What would be a good way to cache the result of the necessary first request?</p>

angular 2 check if model change on component
|
<p>First, my code is working. This question is about if I am doing the proper thing and if I am using the power of angular 2. I come from angular 1 and still learning angular 2 core concepts. </p>
<p>Let's start: </p>
<p>Given an angular 2 app (RC.4) I have a calendar component which render a Calendar as view. Each calendar's day is "decorated" RED (busy) or GREEN (free) depending the result coming for an API rest call. If there is not data for a given day the day is not decorated at all.</p>
<p>So, I have the following Observable in calendar's @component. Once it is resolved, a property of the component "entries" is filled with the response. (The response is an array of day objects with a property "dayStatus" set to busy / green). </p>
<pre><code> ngOnInit() {
this.calendarService.getAll().subscribe(
response => {
this.entries = response.json();
}
);
}
</code></pre>
<p>The calendar template has a ngClass which resolves to decorateDay() handler:</p>
<pre><code><span class="day" *ngFor="let day of week.days"
[ngClass]="decorateDay(day)">
{{ day.number }}
</span>
</code></pre>
<p>Every "day", therefore, in a declarative way looks if it should be decorated green or red through the handler decorateDay(day).
It works as follows: "day" is passed as parameter and is used as key for retrieving the relevant object from the JSON array. From the object property a string green / red is passed to the view and decorated by CSS using ngClass. </p>
<pre><code> decorateDay(day) {
let dayFormatted = day.date.format("YYYY-MM-DD");
//when observable was resolved entries is not undefined.
if (typeof this.entries !== 'undefined') {
let data = this.entries[dayFormatted];
if (typeof data !== 'undefined') {
return data.dayStatus;
}
}
}
</code></pre>
<p><strong>And here comes my question:</strong> I don't know when "entries" will be defined so <strong>I check in the handler if undefined.</strong> Looks like when the entries is filled the component <em>Magically</em> recheck again the handler (through change detection). I am ok with that BUT, There is not a better way of checking when a property of the component has changed? Maybe decorating the property with @resolved or using a lifecycle hook..? I don't like the way I am doing it!</p>
<p>Hope some of you can give some pointers. Thanks in advance!</p>
<p>PS: The binding with the model property could be done on the template itself but I want to use a handler because it gives me more flexibility about how to decorate the given day in the future.</p>

Simple Text GUI (TUI) Using NCurses and C to Display System Info
|
<p>I am just beginning to toy around with combining ncurses and C to develop a very minimal TUI. The purpose of the TUI is to greet users with a basic login/welcome screen. The goal would be to display basic system information like the operating system, available memory, IP address, etc. Nothing beyond read-only. </p>
<p>What would be the best way to go about doing this? The part I'm struggling with is interfacing the shell commands like <code>df</code>, <code>ls</code>, <code>ifconfig</code>, etc with variables that I can then display or print in ncurses and C. I know something like this can be done, as well as calling the system command with a string, but this seems somewhat bulky:</p>
<pre><code>#include <ncurses.h>
#include <stdlib.h>
#include <stdio.h>
int main(void) {
FILE *pp;
initscr();
cbreak();
if ((pp = popen("df", "r")) != 0) {
char buffer[BUFSIZ];
while (fgets(buffer, sizeof(buffer), pp) != 0) {
addstr(buffer);
}
pclose(pp);
}
getch();
return EXIT_SUCCESS;
}
</code></pre>
<p>Are there any methods to execute a command in the command line from within a C program and then selectively access the output of that command for later display? Or is this information generally stored somewhere in a parseable file on the machine? I'm new to trying to pull system information/use the command line in a "TUI" sense and any help would be appreciated. Thanks so much in advance!</p>

Override Arrow Function in Child Class
|
<p>I use arrow functions in my classes instead of methods because they allow me to use the "this" keyword, and keep the "this" meaning the class itself, rather than the method. </p>
<p>I have an abstract class that defines an empty arrow function that is to be overridden by the child class. Correction, it was originally this:</p>
<pre><code>abstract _configureMultiselect(): void;
</code></pre>
<p>but trying to override that with an arrow function caused this:</p>
<pre><code>Class 'CategorySelect' defines instance member function '_configureMultiselect', but extended class 'SearchFilterCategorySelect' defines it as instance member property.
(property) Select.SearchFilterCategorySelect._configureMultiselect: () => void
</code></pre>
<p>So I changed it to an empty arrow function in the parent class:</p>
<pre><code>_configureMultiselect = () => {};
</code></pre>
<p>But when I try to override that, well, it just doesn't override it, so my <code>_configureMultiselect</code> in the child class is empty, when I obviously want it to have a function. Here is my code:</p>
<pre><code>interface ICategorySelect {
multiselectConfiguration: Object;
numberOfCategories: KnockoutObservable<number>;
allSelected: KnockoutObservable<boolean>;
selectedCategories: KnockoutObservableArray<Category>;
categories: KnockoutObservableArray<Category>;
}
abstract class CategorySelect implements ICategorySelect {
multiselectConfiguration: Object;
numberOfCategories: KnockoutObservable<number>;
allSelected: KnockoutObservable<boolean>;
selectedCategories: KnockoutObservableArray<Category>;
categories: KnockoutObservableArray<Category>;
constructor() {
this._configureMultiselect();
this._instantiateCategories();
this.numberOfCategories = ko.observable(7);
this.allSelected = ko.observable(false);
}
_configureMultiselect = () => {};
_instantiateCategories = () => {
this.categories = ko.observableArray([
new Category("Meat", 1),
new Category("Dairy", 2),
new Category("Confectionary", 3),
new Category("Dessert", 4),

new Category("Grocers", 6),
new Category("Restaurants", 5),

]);
}
}

super();

_configureMultiselect = () => {
this.multiselectConfiguration = {
buttonWidth: '100%',
buttonContainer: '<div style="height: 64px;" />',

var self = this;
$('#category-select option:selected').each(function() {
self.selectedCategories.push(

)

console.log(this.selectedCategories());
if(this.selectedCategories().length < this.numberOfCategories()) {

Injected service is undefined right in the constructor
|
<p>For the note, I'm quite uninitiated to Angular (1 or 2 for that matter).</p>
<p>I'm trying to write a "super" layer of Http to avoid having to put the same headers everywhere.</p>
<pre><code>import {Http, ConnectionBackend, RequestOptions, Response, Headers} from '@angular/http';
import {Observable} from 'rxjs';
import {LoadingService} from "../../services/loading.service";
export class HttpLoading extends Http {
constructor(backend: ConnectionBackend, defaultOptions: RequestOptions,
private _ls: LoadingService )
{
super(backend, defaultOptions);
}
getPostPutHeader() {
var authHeader = new Headers();
authHeader.append("Authorization", "Bearer "+ localStorage.getItem('token') );
authHeader.append('Content-Type', 'application/json');
return authHeader;
}
post(url: string, data:any):Observable<Response> {
this._ls.isLoading = true; // Exception here: this._ls is undefined
return super.post(url, data, { headers: this.getPostPutHeader() })
.map(res => {
this._ls.isLoading = false;
return res;
});
}
}
</code></pre>
<p>And a service to tell when a request is executing; it's injected in the above class HttpLoading.</p>
<pre><code>import {Injectable} from '@angular/core';
@Injectable()
export class LoadingService {
isLoading: boolean = false;
}
</code></pre>
<p>I have a bunch of stuff in my bootstrap, including HttpLoading, LoadingService and ConnectionBackend (for this last one, I get an exception if it's not here).</p>
<pre><code>bootstrap(AppComponent, [
ConnectionBackend,
HttpLoading,
APP_ROUTER_PROVIDERS,
HTTP_PROVIDERS,
LoadingService,
disableDeprecatedForms(),
provideForms()
])
</code></pre>
<p>The problem is that the first time I call <code>HttpLoading</code>'s <code>post</code> method (in yet another service), I get an exception at <code>this._ls.isLoading</code>, because <code>this._ls</code> is undefined, and I can't figure why.</p>
<p>Please tell me if you need more information.</p>

<p>Edit</p>
<p><code>LoadingService</code> is correctly injected in my <code>AppComponent</code> (main component).</p>
<pre><code>//imports
//@Component
export class AppComponent {
requesting:boolean = false;
constructor(public authService: AuthService, private router: Router, private _ls: LoadingService) {

this.router.navigate([route])
.then(() => this._ls.isLoading = false);
}
}
</code></pre>
<hr>
<p>Potential solution</p>
<p>It seems that your public/private parameters must be placed first in the list. I'll let someone more skilled than me explain why, though...</p>
<pre><code>export class HttpLoading extends Http {
constructor(private _ls: LoadingService, backend: ConnectionBackend, defaultOptions: RequestOptions) {

Java : HttpSession timeout filter check returns valid session object
|
<p>My Web App is purely JS app with crossroads js for routing.
For Login I'm using j_security_check FORM Auth and /LogOut servlet to invalidate session.</p>
<p><strong>Issue 1</strong>
The real issue comes when the session is timed out, the login.html is rendered in part of the page with no css, with error 'Resource interpreted as Stylesheet but transferred with MIME type text/html'</p>
<p>When using filter </p>
<pre><code><filter>
<description>Session Timeout Filter</description>
<filter-name>SessionTimeoutFilter</filter-name>
<filter-class>filters.SessionTimeoutFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>SessionTimeoutFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
....
<session-config>
<session-timeout>1</session-timeout>
</session-config>
</code></pre>
<p>and JAVA code</p>
<pre><code>public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain)
throws IOException, ServletException {
HttpServletRequest req = null;
HttpSession session = null;
try {
req = (HttpServletRequest) request;
session = req.getSession(false);
if (session != null && !session.isNew()){
LOGGER.log("Session is Valid");
chain.doFilter(request, response);
}else{
LOGGER.log("Session is Invalid");
req.getRequestDispatcher("/login.html?loggedOut=true").forward(request, response);
}
} catch (Throwable t) {
}
}
</code></pre>
<p><strong>Issue 2</strong>
When the filter runs after say inactive 2-3 mins, it prints "Session is Valid". Why is it so?</p>

Opscenter 6.0 Start up issue
|
<p>Yesterday, I tried to install opscenter and initiated import of existing DSE 5.0 cluster. It failed with certain errors which pointed out that installed version was not opscenter 6.0. root cause - opscenter installation was done from datastax community repo and not enterprise one. I corrected repo information to pointed to enterprose repo, removed existing opscenter 5.2.4, installed new opscenter 6.0 - All looks good. finally when i started the service - startup failed, opscenter fails to start and nothing comes in log files.</p>
<p>I did following to remove opscenter 5.x and to install opscenter 6.0</p>
<ol>
<li>Removed Old Version of ospcenter - Sudo yum remove opscenter</li>
<li>Modified repor to point to enterprise repo e.g sudo vi /etc/yum.repos.d/datastax.repo</li>
<li>Installed 6.0-1 version of opscenter . Sudo yum install opscenter</li>
<li>Started Opscenter - sudo service opscenterd start</li>
</ol>
<p>Opscenter process is not running . it starts and get killed after few seconds - i was able to verify it using top command.I went to check log files and can find only two log files startup.log & gc.log.0.current. nothing in log file opscenterd.log</p>
<pre><code>startup.log

How to call a constructor in a Junit Test in Java?
|
<p>Hello I am using Eclipse Luna and I tried to write a unittest with Junit. I want to give a value(null) to a method and it should throw an exception. The Method is a Constructor and the class has a main. What am i doing wrong. Usually I can call a Method like this Package.class.MethodName(Parameter Parameter) </p>
<p>Test class:</p>
<pre><code>public class WebUntisProviderTest {
public static URL url = null;
@Test(expected = IllegalArgumentException.class)
public void WebUntisProvider() {
final URL url = null;
WebUntisProvider prov = new WebUntisProvider(url);
assertNotNull("object was null" , prov.WebUntisProvider(url) );
fail( "url must not be null.");
}
}
</code></pre>
<p>The tested class:</p>
<pre><code>public class WebUntisProvider {
private URL url;
public static void main(String[] args) throws MalformedURLException {
URL test = new URL("HTTP://google.com");
System.out.println(test.getProtocol());
}
public WebUntisProvider(URL url) {
if (url == null)
throw new IllegalArgumentException("url must not be null.");
if (!url.getProtocol().equals("http") && !url.getProtocol().equals("https"))
throw new IllegalArgumentException("url protocol must be http or https.");
this.url = url;
}
}

node.js - express - typeerror: res.json is not a function
|
<p>I am trying to respond to an http request, and I'm getting the following error:</p>
<pre><code>TypeError: req.json is not a function
</code></pre>
<p>Here is where I call it:</p>
<pre><code>app.get('/', function (req, res) {
const channel_name = req.query.channel_name;
const user_name = req.query.user_name;
const text = req.query.text;
var input = text.split(" ");
if (input[0] == "move") { // Make move
game.move(user_name, channel_name, input[1], input[2], function(returnGame) {
req.json(game.getGameStatus(returnGame));
});
}
else {
var boardSize = 3;
if (input.length == 2)
boardSize = input[1];
var newGame = game.startGame(channel_name, user_name, input[0], boardSize);
res.json(game.getGameStatus(newGame));
}
});
app.listen(port);
</code></pre>
<p>game.move and game.startGame both return a JSON called Game. StartGame creates the JSON and returns it, but move loads the JSON from a database and uses a callback to return it.
I get the error when I call req.json from the callback, but it works fine for StartGame.</p>
<p>Any ideas? I've been stuck on this all day and can't seem to figure it out. Any help is appreciated, thanks.</p>

Spring boot exception handling for specific annotated methods
|
<p>Our spring boot controllers have methods called by ajax as well as the standard methods rendering CRUD templates. We'd like to be able to annotate all our ajax methods with a single annotation so that regardless of what type of exception is thrown, we can return a response the ui can handle. </p>
<p>I've been looking at the ControllerAdvice and ExceptionHandler annotations, but I don't think either can be used the way we intend. ControllerAdvice can only cover entire controllers, so any exception handling would also cover the non-ajax methods. Similarly, the ExceptionHandler annotation would handle exceptions from both types of methods.</p>
<p>The current idea is to split the two types of methods, ajax and CRUD, into separate controllers. Is there another way to do this?</p>

React unit tests with Enzyme don't re-bind context of helper functions
|
<p>This is an interesting issue that I came across while trying to refactor some of my React components using AirBnB's React testing library, <a href="https://github.com/airbnb/enzyme" rel="nofollow">Enzyme</a>.</p>
<p>I think the best way to explain my problem is through an example.</p>
<p>Here is a small React component that will display a message depending on the props it receives from its parent component:</p>
<p><strong>test.js:</strong></p>
<pre><code>import React from 'react';
function renderInnerSpan() {
const {foo} = this.props;
if (foo) {
return <span>Foo is truthy!</span>;
}
return <span>Foo is falsy!</span>;
}
export default class extends React.Component {
render() {
return (
<div>
{renderInnerSpan.call(this)}
</div>
);
}
}
</code></pre>
<p>And here is a test suite for this component with two passing tests:</p>
<p><strong>test.spec.js:</strong></p>
<pre><code>import Test from '../../src/test';
import React from 'react';
import {shallow} from 'enzyme';
import {expect} from 'chai';
describe('Test Suite', () => {
let renderedElement,
expectedProps;
function renderComponent() {
const componentElement = React.createElement(Test, expectedProps);
renderedElement = shallow(componentElement);
}
beforeEach(() => {
expectedProps = {
foo: true
};
renderComponent();
});
it('should display the correct message for truthy values', () => {
const span = renderedElement.props().children;
expect(span.props.children).to.equal('Foo is truthy!');
});
it('should display the correct message for falsy values', () => {
expectedProps.foo = false;
renderComponent();
const span = renderedElement.props().children;
expect(span.props.children).to.equal('Foo is falsy!');
});
});
</code></pre>
<p>This works fine, but the Test component's current implementation isn't as efficient as it could be. By using <code>.call(this)</code>, it is creating a new function every time the <code>render()</code> function is called. I could avoid this by binding the correct context of <code>this</code> in the component's constructor, like so:</p>
<pre><code>export default class extends React.Component {
constructor(props) {
super(props);
renderInnerSpan = renderInnerSpan.bind(this);
}
render() {
return (
<div>
{renderInnerSpan()}
</div>
);
}
}
</code></pre>
<p>After this change, the component still works as intended, but the tests start failing:</p>
<pre><code>AssertionError: expected 'Foo is truthy!' to equal 'Foo is falsy!'
Expected :Foo is falsy!
Actual :Foo is truthy!
</code></pre>
<p>I added a <code>console.log(props.foo)</code> in the constructor, which confirmed that the constructor was still being called when I expected it to, and the props it's receiving are correct. However, I added a <code>console.log(foo)</code> inside of <code>renderInnerSpan</code>, and it looks like the value is true all the time, even after re-rendering the component with its <code>foo</code> prop explicitly set to <code>false</code>.</p>
<p>It looks like <code>renderInnerSpan</code> is only be bound once, and Enzyme is re-using this for every single test. So, what gives? I'm re-creating my component in the test, which is calling its constructor with the values I expect - why is my bound <code>renderInnerSpan</code> function continuing to use old values?</p>
<p>Thanks in advance for the help.</p>

Spring Security BCrypt Password Encoder - Workload Factor
|
<p>I'm integrating Spring Security's Bcrypt Password Encoder into a new application, and while testing I noticed that the workload doesn't seem to have an effect when matching a password using two encoders with different work factors. Take the following example:</p>
<pre><code>public static void main(String[] args) {
PasswordEncoder strongEncoder = new BCryptPasswordEncoder(12);
PasswordEncoder weakEncoder = new BCryptPasswordEncoder(6);
String password = "SomePassword@@";
String strongEncodedPass = strongEncoder.encode(password);
String weakEncodedPass = weakEncoder.encode(password);
//Prints true
System.out.println(weakEncoder.matches(password, strongEncodedPass));
//Prints true
System.out.println(strongEncoder.matches(password, weakEncodedPass));
}
</code></pre>
<p>Shouldn't both print statements results in false since the encoders are using different work loads?</p>
<p>The above sample was tested using spring-security-core-4.1.0.RELEASE.jar in Java 8</p>

How to extract values from Eureka forms in swift to local variables?

<p>While I try to pass it to temporary variables it doesn't seem to happen.</p>
<p>Although there are no errors while building the app, once I try to enter a value for "rateOfPaddy", it fails, citing "fatal error: unexpectedly found nil while unwrapping an Optional value"</p>
<p>Please let me know if I'm doing anything wrong, either related to Swift or Eureka?</p>
<pre><code> form +++ Section()

$0.tag = "RecordDateTag"
$0.title = "Date"
$0.value = NSDate()

cell.textLabel?.textColor = UIColor.blackColor()
}.onCellHighlight { _ in
if let dateInput = formInput["RecordDateTag"] as? String {
self.dateInputValue = dateInput
}
}.onCellUnHighlight { _ in
if let dateInput = formInput["RecordDateTag"] as? String {
self.dateInputValue = dateInput
}
}
</code></pre>
<p>I used .onChange callback to check and pass the information to local variables, which was of no use. .onCellHighlight and .onCellUnHighlight combination didn't do the trick either!!</p>

Kong in Docker : Configuring API endpoints without curl

<p>Is there a way to add API endpoints in Kong without using curl? I have Kong up and running in a docker container using docker-compose and I would like to be able to pass in a configuration file (or what-have-you) on container spin up that outlines the endpoints I would like setup. Is this possible? This is the closest I have found to a solution : <a href="http://blog.toast38coza.me/kong-up-and-running-part-2-defining-our-api-gateway-with-ansible/" rel="noreferrer">http://blog.toast38coza.me/kong-up-and-running-part-2-defining-our-api-gateway-with-ansible/</a></p>

Sonarqube incorrect report for duplicated code
|
<p>I am a newbie to SonarQube and trying to use the tool for measuring my product quality. </p>
<p>In some cases, I found that the duplicated lines is reported incorrectly by SonarQube . The number of lines of code is less than the duplicated lines. How can that be ? Either the count of lines of code is incorrect or the count of duplicated lines is incorrect.</p>
<p>Assuming it could be a problem with my code alone, I visited the demo page of Sonarqube <a href="https://sonarqube.com/component_measures/domain/Duplications?id=com.adobe%3Aas3corelib" rel="nofollow noreferrer">https://sonarqube.com/component_measures/domain/Duplications?id=com.adobe%3Aas3corelib</a></p>
<p>There as well , I found that one of the cases the lines of code is less than duplicated lines.</p>
<p>Where is the issue ? How do I address it ?</p>

Rails: datetime_field does not display control buttons
|
<p>I have a form, where I use <code>date_field</code> helper and it works well, the control buttons are shown, but when I change it with a <code>datetime_field</code> the field is displayed but control buttons are no displayed.</p>
<p>My <code>date_field</code> which works fine:</p>
<pre><code>=f.date_field :publishing_date, placeholder: "yyyy-mm-dd", class: "form-control"
</code></pre>
<p>the <code>datetime_field</code> which does not shown controls:</p>
<pre><code>=f.datetime_field :publishing_date, class: "form-control"
</code></pre>
