Russian characters encoding in SQL Server | <p>I want to encode Russian Character correctly in SQL Server. I am using <code>fnEncodeURL</code> method of SQL Server.</p>
<p>For example:</p>
<pre><code>select dbo.fnEncodeURL('пвы Открытые панели для совместной работы .')
</code></pre>
<p>which shows me </p>
<pre><code>%3F%3F%3F%20%3F%3F%3F%3F%3F%3F%3F%3F%20%3F%3F%3F%3F%3F%3F%20%3F%3F%3F%20%3F%3F%3F%3F%3F%3F%3F%3F%3F%3F%20%3F%3F%3F%3F%3F%3F%20.
</code></pre>
<p><code>%3F</code> means <code>?</code> so if we will decode it it would be "??? ???????? ?????? ??? ?????????? ?????? ." </p>
<p>which is incorrect.</p>
<p>So please let me know the correct way so that I could get russian characters in result instead of question marks.</p>
<p>Thanks in advance</p> | 1 |
CopyAllFilesToSingleFolderForPackageDependsOn and Web Deploy | <p>I am using Web Deploy feature of Visual Studio 2015 to deploy my Type Script SPA project to my staging server.</p>
<p>I want the deployment process to copy (and rename) some deployment specific files from /Deployment folder of my project to other specific locations of the project.</p>
<p>One such example is:</p>
<p>[project_root]/Deployment/index.remote.debug.html ---> [project_root]/index.html</p>
<p>I managed to achieve this using the following section in my publish profile (.pubxml):</p>
<pre class="lang-xml prettyprint-override"><code><Target Name="index_html">
<ItemGroup>
<_CustomFiles Include="Deployment/index.remote.debug.html" />
<FilesForPackagingFromProject Include="%(_CustomFiles.Identity)">
<DestinationRelativePath>index.html</DestinationRelativePath>
</FilesForPackagingFromProject>
</ItemGroup>
</Target>
<Target Name="extractor_config">
<ItemGroup>
<_CustomFiles Include="Deployment/extractor.config.remote.debug.js" />
<FilesForPackagingFromProject Include="%(_CustomFiles.Identity)">
<DestinationRelativePath>extractor.config.js</DestinationRelativePath>
</FilesForPackagingFromProject>
</ItemGroup>
</Target>
<PropertyGroup>
<CopyAllFilesToSingleFolderForPackageDependsOn>
index_html;
$(CopyAllFilesToSingleFolderForPackageDependsOn);
</CopyAllFilesToSingleFolderForPackageDependsOn>
<CopyAllFilesToSingleFolderForPackageDependsOn>
extractor_config;
$(CopyAllFilesToSingleFolderForPackageDependsOn);
</CopyAllFilesToSingleFolderForPackageDependsOn>
</PropertyGroup>
</code></pre>
<p>But this works only when publishing to file system with 'File System' option.
When publishing to my staging server using 'Web Deploy' option, I see no effect.
The application is correctly deployed but respective files don't get copied/renamed.</p>
<p>There is also no error message in Visual Studio output related to such a web deploy.</p>
<p>It makes no difference if I deploy as non-admin or admin.</p>
<p>Does anybody know, where is the problem?</p>
<p>With respect to MSBuild I am a total layman and this is my first encounter. I've put this together only with help of other people's online experience.</p> | 1 |
Read data from text format into Python Pandas dataframe | <p>I am running Python 2.7 on Windows.</p>
<p>I have a large text file (2 GB) that refers to 500K+ emails. The file has no explicit file type and is in the format:</p>
<pre><code>email_message#: 1
email_message_sent: 10/10/1991 02:31:01
From: [email protected]| Tom Foo |abc company|
To: [email protected]| Alex Dee |abc company|
To: [email protected]| Ben For |xyz company|
email_message#: 2
email_message_sent: 10/12/1991 01:28:12
From: [email protected]| Tim Tee |abc company|
To: [email protected]| Tom Foo |abc company|
To: [email protected]| Alex Dee |abc company|
To: [email protected]| Ben For|xyz company|
email_message#: 3
email_message_sent: 10/13/1991 12:01:16
From: [email protected]| Ben For |xyz company|
To: [email protected]| Tom Foo |abc company|
To: [email protected]| Tatiana Xocarsky |numbers firm |
...
</code></pre>
<p>As you can see, each email has the following data associated with it:</p>
<p>1) the time it was sent</p>
<p>2) the email address who sent it</p>
<p>3) the name of the person who sent it</p>
<p>4) the company that person works for </p>
<p>5) every email address that received the email</p>
<p>6) the name of every person who received the email</p>
<p>7) the company of every person who received the email</p>
<p>In the text files there are 500K+ emails, and emails can have up to 16K recipients. There is no pattern in the emails in how they refer to names of people or the company they work at. </p>
<p>I would like to take this large file and manipulate it in <code>python</code> so that it ends up as a <code>Pandas</code> <code>Dataframe</code>. I would like the <code>pandas</code> <code>dataframe</code> in the format like the screenshot from <code>excel</code> below:</p>
<p><a href="https://i.stack.imgur.com/C1a69.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/C1a69.png" alt="Sample Data Structure"></a></p>
<p><strong>EDIT</strong></p>
<p>My plan to solve this is to write a "parser" that takes this text file and reads in each line, assigning the text in each line to a particular columns of a <code>pandas</code> <code>dataframe</code>.</p>
<p>I plan to write something like the below. Can someone confirm that this is the correct way to go about executing this? I want to make sure I am not missing a built-in <code>pandas</code> function or function from a different <code>module</code>. </p>
<pre><code>#connect to object
data = open('.../Emails', 'r')
#build empty dataframe
import pandas as pd
df = pd.DataFrame()
#function to read lines of the object and put pieces of text into the
# correct column of the dataframe
for line in data:
n = data.readline()
if n.startswith("email_message#:"):
#put a slice of the text into a dataframe
elif n.startswith("email_message_sent:"):
#put a slice of the text into a dataframe
elif n.startswith("From:"):
#put slices of the text into a dataframe
elif n.startswith("To:"):
#put slices of the text into a dataframe

sbt: cross-publish from build.sbt | <p>Currently, I'm using SBT scripted plugin for testing. To publish a plugin into the local repository, following code snippet in build.sbt is used:</p>
<pre><code>crossScalaVersions := Seq(scalaVersion.value,"2.11.7")
scriptedDependencies := {
val local = publishLocal.value
}
</code></pre>
<p>This way the artefact gets published into the local repository, but only for the version <code>scalaVersion.value</code>. I would like to have it cross-published for both scala versions. How can I do that?</p> | 1 |
Related products by variant using metafields for Shopify Liquid | <p>I'm trying to build on caroline's solution for related products with metafields to build related product variants. I.e when you click on the white color variant for a desk, you will see the white variant of a chair as a related product. (As opposed to linking the desk product to the chair product regardless of variant.) Caroline's solution is here: <a href="https://gist.github.com/carolineschnapp/1003334" rel="nofollow">https://gist.github.com/carolineschnapp/1003334</a> and below is my code. Right now it's putting the same product twice on page load, and nothing happens when a different vairant is selected. The way I am formatting the metafield value for each variant is by putting "related-product-handle-1, variant-id-1, related-product-handle-2,variant-id-2, related-product-handle-3, variant-id-3" instead of just the product handles.</p>
<pre><code>{% assign image_size = 'compact' %}
{% assign heading = 'Related Products' %}
{% if product.selected_or_first_available_variant.metafields.recommendations.productHandles %}
<h3>{{ heading }}</h3>
<ul class="related-products"></ul>

<p>Answer edited: The first was extremely helpful once I made some corrections to syntax errors and a couple of short additions. Here is my edited version of the answer for anyone who may need it: </p>
<p>Product.liquid:</p>
<pre><code> {% for variant in product.variants %}
{% capture metafield_data %}{% endcapture %}
{% assign related_products = variant.metafields.recommendations.productHandles | split: '|' %}
{% for related_product in related_products %}
{% assign metafield_items = related_product | split: ',' %}
{% assign r_p = metafield_items[0] %}
{% assign r_v = metafield_items[1] | plus: 0 %}
{% assign r_n = all_products[r_p].title %}
{% for related_variant in all_products[r_p].variants %}
{% if related_variant.id == r_v %}
{% assign r_i = related_variant.image.src | img_url: 'small' %}
{% endif %}
{% endfor %}
{% capture metafield_data %}{{metafield_data}}{{ r_p }},{{ r_v }},{{ r_i }},{{ r_n }}{% unless forloop.last %}|{% endunless %}{% endcapture %}
{% endfor %}
<option id="{{ variant.id }}" data-metafield="{{ metafield_data }}" {% if variant == product.selected_or_first_available_variant %} selected="selected" {% endif %} value="{{ variant.id }}">{{ variant.title }} - {{ variant.price | money }}- {{ related_products.size }}</option>

<p>The only thing I'm nervous about is the fact that I am copying over the data from the 'product-select' dropdown over to the 'single-option-selector' dropdown. I am doing this because there is no template for rendering the single-option-selector, it seems to be getting added through javascript. If anyone has any insight into manipulating the single-option-selector in liquid, please let me know. Thank you!!</p> | 1 |
jQuery input number convert Persian/Arabic numbers to English numbers | <p>I have a input field of type <code>number</code>. I want to accept Persian/Arabic numbers as well in this field. I wanted to convert these numbers to English using jQuery, but it seems I can't retrieve these values.</p>
<pre><code>jQuery('input[type="number"]').on('input', function() {
console.log(jQuery(this).val());
});
</code></pre>
<p>For non-English numbers <code>val()</code> is empty string. Is there any way to get the value of a number input field, if the value is not a English number?</p>
<p>UPDATE:</p>
<pre><code>Persian numbers: ۰ ۱ ۲ ۳ ۴ ۵ ۶ ۷ ۸ ۹
English numbers: 0 1 2 3 4 5 6 7 8 9
</code></pre>
<p>UPDATE2:</p>
<p>Looks like Firefox returns the correct <code>val</code> but Chrome returns empty string. So my question is applicable on Google Chrome.</p> | 1 |

Blocking operation in Qt Quick | <p>I want to perform a long task when a button is clicked. I want this task to block the UI, because the application cannot function until the task is done. However, I want to indicate to the user that something is happening, so I have a <code>BusyIndicator</code> (that runs on the render thread) and is set to display before the operation begins. However, it never renders. Why?</p>

emit runningChanged();
// Try to ensure that the scene graph has time to begin the busy indicator
// animation on the render thread.

Device compabilities issue in iOS | <p>We uploaded an app where in the first version we added to device capabilities “telephony” to restrict only iPhone devices in the info plist. In the second version we forgot to add “telephony” and we submitted to the App store. Third version we are planning to upload with device capabilities as “telephony” but while submitting to the App Store it shows the warning:</p>
<blockquote>
<p>This bundle is invalid. The key <code>UIRequiredDeviceCapabilities</code> in the
Info.plist may not contain values that would prevent this application
from running on devices that were supported by previous versions.</p>
</blockquote>
<p>How can we resolve this issue, if we require the device capability “telephony” for application lifetime, but due to my mistake on the second version we forgot to add the required device capabilities? What is the solution for it? </p>
<p>Thanks in advance.</p> | 1 |

PUT request made with Python requests module has no data | <p>I am developing an Python REST api and for server side I'm using Django with django-rest-framework. I managed to successfully test my api with AdvancedRestClient in chrome, but I can't get it working with python requests.</p>
<p>My ARC request looks like this:
<a href="https://i.stack.imgur.com/am85h.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/am85h.png" alt="enter image description here"></a></p>
<p>And for my test Python request I wrote the following code:</p>
<pre><code>import requests
import json
payload = {"TimeStamp": "2016-02-07T13:38:16Z", "DateInserted": "2016-02-07T13:38:18Z", "Value": 17.145, "Sensor": 1}
url = "http://127.0.0.1:8000/api/Readings"
headers = {"Content-Type": "application/json", "Authorization": "966271f8-94a3-4232-95f7-953f3b7989f3"}
r = requests.put(url, data=json.dumps(payload), headers=headers)
</code></pre>
<p>I tried many different things as using <code>json=</code> instead of <code>data=</code> but my request always seem to have no data content when they arrive to my server side. I searched the web but couldn't find any viable examples of using POST with requests so I'm hoping someone has some first-hand experience in their sleeve to share with me.</p>
<p><strong>Update:</strong>
The following code now works with django-rest-framework.</p>
<pre><code>payload = {"TimeStamp": "2016-02-07T13:38:16Z", "DateInserted": "2016-02-07T13:38:18Z", "Value": 12.123, "Sensor": 1}
url = "http://127.0.0.1:8000/api/Readings/"
headers = {"Content-Type": "application/json", "Authorization": "966271f8-94a3-4232-95f7-953f3b7989f3"}
r = requests.put(url, data=json.dumps(payload), headers=headers)

Can't close Kivy app or avoid fullscreen | <p>I am new to Kivy and trying to find my way around. Whenever I create and run an app, it displays as a full-screen that I am unable to close without disconnecting the power (which I know is not ideal, but that's exactly why I am desperate to fix it!). </p>
<p>Shortcuts that are suggested to work (Esc, Ctrl+C, Ctrl+Alt+break) don't. I have attempted changing the config settings at the beginning of the script as follows:</p>
<pre><code>from kivy.config import Config
Config.set('graphics', 'fullscreen', 0)
Config.write()
</code></pre>
<p>I've also tried variations on the theme - 0 as a string, 1 as both an integer and string (and trying to provide a width and height for the window) but with no perceivable change. Even if this did work, it would not be the ideal fix given that I would probably want to be able to run things full-screen in the end!</p>
<p>Given that each time I've tried changing something I've had to restart the pi by disconnecting the power, playing around has been quite time-consuming!
Does anybody have any suggestions about how I should proceed?</p>
<p>I'm currently using:<br>
Raspberry Pi 2 Model B connected to normal TV (many people having problems have been using a touchscreen, but that is not true for me)<br>
Raspbian Jessie, Linux 8<br>
Python 2.7<br>
I'm afraid I don't know how to check details about the Kivy module I have downloaded.</p>
<p>I'm very new to this, so apologies if I don't manage to provide all of the relevant information.</p>
<p>Full code I am trying to run (excluding the above config changes): </p>
<pre><code>import kivy
kivy.require('1.9.2') #may be part of the problem - not 100% sure this is correct
from kivy.app import App
from kivy.uix.label import Label
class MyApp(App):
def build(self):
return Label(text='Hello world')

How to get files from SFTP using TSQL or SQL Server Agent? | <p>I need to get files from SFTP and stored them on server. Is there any way I can do that using TSQL or SQL Server Agent? I do not want to use Third party tools or SSIS or PowerShell Script or WinSCP.</p> | 1 |
Chrome Custom Tabs, deep linking with Oauth2 | <p>Hi I'm using Google Chrome Custom Tabs for a project and I have a few issues with deep linking. </p>
<p>I need to authenticate the users through a oauth2 process using chrome custom tabs. The user is sent to the authentication form then types is login/password. Then it is redirected to a url like <code>myapp://something</code>. An intent is then triggered and the user is sent back to the app.</p>
<p>The process is working well at first launch when the user is logging in through the authentication form. However, if I try to get another authentication code, I get an <code>ERR_UNKNOWN_URL_SCHEME</code> error and the app stays on the custom tabs.</p>
<p>Here are the three cases I tested : </p>
<p><strong>1st case : Chrome custom tab, forcing the user to use the authentication form</strong></p>
<p>-The user is sent to the authentication form</p>
<p>-A 302 redirect is done to a custom url</p>
<p>-The user is switched to the app</p>
<p><strong>2nd case : Chrome custom tab (using the session cookie)</strong></p>
<p>-The user is sent to the authentication website</p>
<p>-A 302 redirect is done to a custom url</p>
<p>-An <code>ERR_UNKNOWN_URL_SCHEME</code> occurs</p>
<p><strong>3rd case : Chrome browser (using the authentication form or the session cookie)</strong></p>
<p>-The user is sent to the authentication website</p>
<p>-A 302 redirect is done to a custom url</p>
<p>-The user is switched to the app</p>
<p>The full process is working with the chrome browser but I have to make it work with Custom Tabs. Is this behaviour normal ? I mean i read that a user interaction might be needed to use deep links but everything is working well with the chrome brower. Without this deep linking process, how is it possible to do SSO with custom tabs ?</p>
<p>PS : Here's a video to explain my issue and the tests done <a href="https://www.youtube.com/watch?v=Y-4uLpUv1lA" rel="nofollow">https://www.youtube.com/watch?v=Y-4uLpUv1lA</a></p> | 1 |

Python montage a plot on OpenCV image and record as video | <p>Assume that you have a temperature data with sampling rate 512. I want to record this data by synchronized with the camera images. The resulting record going to be just a video file. </p>
<p>I can plot this data with matplotlib and pyqtgraph. </p>
<p>I did it with matplotlib but video sampling rate is decreasing. Here is the code with random incoming data.</p>
<pre><code>import cv2
import numpy as np
import matplotlib.pyplot as plt
cap = cv2.VideoCapture(0) # video source: webcam
fourcc = cv2.cv.CV_FOURCC(*'XVID') # record format xvid
out = cv2.VideoWriter('output.avi',fourcc, 1, (800,597)) # output video : output.avi
t = np.arange(0, 512, 1)# sample time axis from 1 to 512
while(cap.isOpened()): # record loop
ret, frame = cap.read()# get frame from webcam
if ret==True:
nse = np.random.randn(len(t))# generate random data squence
plt.subplot(1, 2, 1)# subplot random data
plt.plot(t, nse)
plt.subplot(1, 2, 2)# subplot image
plt.imshow(frame)
# save matplotlib subplot as last.png

Does a detached std::thread need to be deleted after it terminates? | <p>I create a <code>new</code> std::thread object, and then <code>detach()</code> it. The thread runs for an arbitrary amount of time, and then terminates itself. Since I created the object with <code>new</code>, do I need to <code>delete</code> it at some point to free up its resources? Or does the thread effectively <code>delete</code> itself upon termination?</p>
<p>If it does effectively <code>delete</code> itself, will something bad happen if I explicitly <code>delete</code> it after it has terminated?</p> | 1 |
Is this one-hot encoding in TensorFlow fast? Or flawed for any reason? | <p>There are a few stack overflow questions about computing one-hot embeddings with TensorFlow, and here is the accepted solution:</p>
<pre><code>num_labels = 10
sparse_labels = tf.reshape(label_batch, [-1, 1])
derived_size = tf.shape(label_batch)[0]
indices = tf.reshape(tf.range(0, derived_size, 1), [-1, 1])
concated = tf.concat(1, [indices, sparse_labels])
outshape = tf.reshape(tf.concat(0, [derived_size, [num_labels]]), [-1])
labels = tf.sparse_to_dense(concated, outshape, 1.0, 0.0)

<p>This is almost identical to the code in an official tutorial: <a href="https://www.tensorflow.org/versions/0.6.0/tutorials/mnist/tf/index.html" rel="nofollow">https://www.tensorflow.org/versions/0.6.0/tutorials/mnist/tf/index.html</a></p>
<p>To me it seems that since <code>tf.nn.embedding_lookup</code> exists, it's probably more efficient. Here's a version that uses this, and it supports arbitrarily-shaped inputs:</p>
<pre><code>def one_hot(inputs, num_classes):
with tf.device('/cpu:0'):
table = tf.constant(np.identity(num_classes, dtype=np.float32))
embeddings = tf.nn.embedding_lookup(table, inputs)
return embeddings

<p>Do you expect this implementation to be faster? And is it flawed for any other reason?</p> | 1 |

Rails initialization checksum error | <p>I'm trying to initialize a new rails app on windows, and running <code>rails new <appname></code> generates everything up to <code>vendor/assets/stylesheets/.keep</code>, but when <code>bundle install</code> is run, rails generates this error:</p>

Error "Expected invocation on the mock once, but was 0 times" when unit testing with moq | <p>I have the following class I want to test:</p>

<p>Specifically, I want to test the GetData method. My unit test looks like this:</p>

<p>The error I am getting happens on the last line:</p>
<pre><code>mockSqlService.Verify(r => r.GetPagedAggregateData(clientId, moduleId, billTypeId, tempResult), Times.Once);
</code></pre>
<p>And the exact error message is this:</p>
<blockquote>
<p>{"\r\nExpected invocation on the mock once, but was 0 times: r =>

Times.Never</p>
<p>Performed invocations:\r\nISqlServiceByModule.GetPagedAggregateData(1,
1, 1, PagedTable)"}</p>
</blockquote>
<p>Any idea why this is happening? It looks to me like the method in question is being called, but Moq doesn't like the parameters for some reason, even though they are the exact same ones in all three invocations, as far as I can tell.</p> | 1 |
Certificate signature validation failed | <p>My website is hosted on Amazon. It is built on the microsoft version of java 1.4.2_13. I noticed emails were not going out. I had not made any changes to the code. I found <a href="http://docs.aws.amazon.com/AWSSdkDocsJava/latest/DeveloperGuide/use-sha256.html" rel="nofollow">this</a> document on amazon's site and followed their directions to find out that our java environment did not pass the test. So, I imported the new ssl root certificate. I can verify that it is in the keystore, but I get the following error message when I run their shaTest and emails are still not being sent. Any help is appreciated. Thanks!</p>

Pass variable as parameter on a Stored Procedure | <p>I have a stored procedure with a SELECT statement and two parameters. I want to call this stored procedure from another one that has a variable declared, and use this variable as one of the parameters.</p>
<p>When I try this: </p>

</code></pre>
<p>It returns some rows as result, but when I try this:</p>

EXEC [dbo].[Testo] @cd_order = 23, @cd_substep = @temp_var1

<p>The result is empty.</p>
<p>The procedure will populate a table variable:</p>
<pre><code>INSERT INTO @Var1Table EXEC [dbo].[Testo] 23, @cd_substep

How to call a function inside a dictionary in python | <p>I am creating a python shell script that will allow the user to enter commands that output a string. But also some commands will call a function, like <strong>help</strong>, or <strong>exit</strong>

Too long saving time in Excel via VBA | <p>Some unusal phenomenon started affecting my macro. I have a relatively big (13MB) excel workbook. <code>ThisWorkbook.Save</code> worked just fine. It took like 10 seconds to save the workbook (without any data changes). Now it takes for 2 minutes. Same goes for <code>ThisWorkbook.Close SaveChanges:=True</code>. I am using <code>Excel 2010</code> on <code>Windows 7</code>.</p>
<p>The strange thing is I can save the workbook manually without any issues, like <code>CTRL+S</code> or using the <code>Save icon</code> in the Excel menu. This way the saving procedure takes less than 10 seconds just as my code used to do it.</p>
<p>The occurence of this unnecessary delay is really bugging me. Do you have any experience with an issue like this? I'm looking for tips to get an approach on the problem.</p>
<hr>
<p>EDIT:</p>
<p>I've changed to <code>xlsb</code> format as was advised and went a little further with testing. There are some cases when the saving time looks appropiate:</p>
<ul>
<li>Significant data changes in lots of sheets (48s)</li>
<li>The <code>Save</code> command is triggered from a newly created <code>module</code> without any other changes (5s)</li>
<li>All my charts (150pcs) are deleted (1s). Apparently each chart gives about 1 extra second to the saving time. I know, i should use one dynamic but the damn label bugs... And it was totally fine before!</li>
</ul>
<hr>
<p>EDIT 2:</p>
<p>The issue has vanished today. <code>Save</code> command works properly again, saving takes for only a few seconds. Dunno what caused the problem, but I am affraid it will be back and will affect my macro some day again. Excel is definitely quirky!</p> | 1 |
laravel uuid not showing in query | <p>I've a postgres database table that uses uuid's as its primary key, via the <strong>webpatser/laravel-uuid</strong> package, and 'readable' web ids via <strong>vinkla/hashids</strong>.</p>
<p>When I query the database, if I <strong>dd()</strong> the response, I see the UUID in full, but if I simply <strong>return</strong>, I instead get an integer.</p>
<p>Presume I've overlooking something obvious, so:</p>
<p><strong>Migration</strong></p>
<pre><code>$table->uuid('id');
$table->string('web_id');
$table->primary('id');
</code></pre>
<p><strong>Model</strong></p>
<pre><code>public function store()
{
$data = [
'id' => Uuid::generate(4)->string,
'web_id' => Hashids::encode(mt_rand(1,1000000)),
</code></pre>
<p>I'm assuming something happens when the data is cast to json, but I'm not sure where'd I'd begin to tackle this...</p>
<p>I also see the same behaviour in artisan tinker, fwiw:</p>
<pre><code> >>> $result = App\Model::firstOrFail()

does not implement methodSignatureForSelector: Unrecognized selector (NSTimer) | <p>I am using an <code>NSTimer</code> in my Swift app in the following way:</p>

let currEvent = self.eventArray[eventIndex]
currEvent?.startEvent()
let nextIndex = eventIndex + 1
NSTimer.scheduledTimerWithTimeInterval((currEvent?.duration)!, target: self, selector: "playEvent(nextIndex)", userInfo: nil, repeats: true)

Render and/or redirect called multiple times in action | <p>I'm using Devise and Pundit.
To create a new profile page, the user has to be authorized to do so.
This has been working fine since I first implemented it, but today it just started acting up with an error message:</p>
<blockquote>
<p>Render and/or redirect were called multiple times in this action.
Please note that you may only call render OR redirect, and at most
once per action. Also note that neither redirect nor render terminate
execution of the action, so if you want to exit an action after
redirecting, you need to do something like "redirect_to(...) and
return".</p>
</blockquote>
<p>Here's my code from my Application controller:</p>
<pre><code> rescue_from Pundit::NotAuthorizedError, with: :user_not_authorized
...
private
def user_not_authorized(exception)
flash[:alert] = "Sorry, you are not authorized to perform this action."
redirect_to(request.referrer || root_path)
end
</code></pre>
<p>Here's my ProfilePage controller:</p>
<pre><code>def new
@profile_page = ProfilePage.new
authorize @profile_page
end
def create
@profile_page = ProfilePage.new(profile_page_params)
respond_to do |format|
if @profile_page.save
format.html { redirect_to @profile_page, notice: 'Profile page was successfully created.' }
format.json { render :show, status: :created, location: @profile_page }
else
format.html { render :new }
format.json { render json: @profile_page.errors, status: :unprocessable_entity }
end
end
authorize @profile_page
end
</code></pre>
<p>Someone suggested that I add this line of code below <code>flash[:alert]</code>:</p>
<pre><code>self.response_body = nil
</code></pre>
<p>But now my user is redirected to the 'new profile' page again, rather than the successful profile page. It also tells the user that they are not authorized to complete this action, despite the fact that it HAS authorized them to do so.</p> | 1 |
How to load a local json file in Xcode for unit test purposes? | <p>So I have added the file <code>testJson1.json</code> to my project. </p>
<p>Within the unit test I have tried to get the filepath without any luck:</p>
<pre><code>NSBundle *bundle = [NSBundle bundleForClass:[self class]];
NSString *filepath = [bundle pathForResource:@"testJson1.json" ofType:@"json"];
</code></pre>
<p>When I look at the project file, I can oddly enough see that the file is added to the resources, I thought unit test files would not be added to the resource to keep the app size down.</p>
<pre><code>8AA238811C5565E80031648E /* testJson1.json in Resources */ = {isa = PBXBuildFile; fileRef = 8AA2387F1C5565E80031648E /* testJson1.json */; };
</code></pre>
<p>What am I missing please?</p>

Retrieve paginated data recursively using promises | <p>I'm using a function which returns data in a paginated form. So it'll return max 100 items and a key to retrieve the next 100 items. I want to retrieve all the items available.</p>
<p>How do I recursively achieve this? Is recursion a good choice here? Can I do it any other way without recursion?</p>
<p>I'm using Bluebird 3x as the promises library.</p>
<p>Here is a snippet of what I'm trying to achieve:</p>
<pre><code>getEndpoints(null, platformApplication)
.then(function(allEndpoints) {
// process on allEndpoints
});
function getEndpoints(nextToken, platformApplication) {
var params = {
PlatformApplicationArn: platformApplication
};
if (nextToken) {
params.NextToken = nextToken;
}
return sns.listEndpointsByPlatformApplicationAsync(params)
.then(function(data) {
if (data.NextToken) {
// There is more data available that I want to retrieve.
// But the problem here is that getEndpoints return a promise
// and not the array. How do I chain this here so that
// in the end I get an array of all the endpoints concatenated.
var moreEndpoints = getEndpoints(data.NextToken, platformApplication);
moreEndpoints.push.apply(data.Endpoints, moreEndpoints);
}
return data.Endpoints;
});
}
</code></pre>
<p>But the problem is that if there is more data to be retrieved (see <code>if (data.NextToken) { ... }</code>), how do I chain the promises up so that in the end I get the list of all endpoints etc.</p> | 1 |
How to cancel execution of a long-running async task in a C# Winforms app | <p>I'm a quite inexperienced c# programmer and need help on managing the flow of my program. It is a WinFormApp that asks for multiple user inputs and then uses them to establish serial communication with a device in order to make measurements. The measurements are made in an async method that takes about 20 minutes to run. So I'm using </p>
<pre><code> void main()
{
//Setup
}
private void button1_Click(object sender, EventArgs e)
{
await measurements();
//Plot results
}
private async Task measurements()
{
while(true){
//Make some measurements
await Task.Delay(120000);
//Make measurements, present data in the UI form.
//return if done
}
}
</code></pre>
<p>Now I need to make a button which enables the user to cancel the measurements in order to change some input or parameter and then restart the measurements. So I added a "Cancel"-button. </p>
<pre><code> private void button7_Click(object sender, EventArgs e)
{
textBox64.Enabled = true;
button6.Enabled = true;
button5.Enabled = true;
textBox63.Enabled = true;
button3.Enabled = true;
trackBar1.Enabled = true;
timer.Enabled = true;
button7.Enabled = false;
clearData();
// measurement.Stop();
}
</code></pre>
<p>Now I do not know how to manage the flow of the program. I have tried to make a <code>try-catch</code> structure in <code>button1_Click()</code> and throw an Exception from <code>button7_Click</code>, but it doesn't get through to <code>button1_Click()</code>.<br>
Then I tried to run <code>measurements()</code> on a new thread. But the thread does not have access to 70-ish UI items on my main form.<br>
And even I wont sink as low as trying Goto. </p>
<p>What I need is advice on how you would program in this situation in order to get a good control of the application and not compromise the flow of the program with risky stuff like exceptions and Goto.</p> | 1 |

How to tap-to-focus with react-native-camera | <p>I would like to let the user focus to take picture. But I don't know how it works.</p>
<p>I found on the documentation the section related to the problem : <a href="https://github.com/lwansbrough/react-native-camera#onfocuschanged" rel="noreferrer" title="gog">react-native-camera</a> But is there any example to view how it works ? I don't any idea to implement this.</p>
<p>Furthermore, the <a href="https://github.com/lwansbrough/react-native-camera#defaultonfocuscomponent" rel="noreferrer">default option</a> didn't seem to work. I didn't have any visual feedback when I pressure camera's screen and it didn't seems to focus.</p>
<p>Someone can help me on this point ?</p>
<p><strong>Update : Solution</strong></p>
<p>It appears a bug was fix since long time, but at this time, the dependencie isn't up-to-date, so the feature didn't work. As a workaround before a new release <code>> 0.38.0</code>, add this link <code>https://github.com/lwansbrough/react-native-camera.git#8f37727be69132cdbfed95255c8bd010a1db5c7d</code> (with the hash of the last commit on master) to your <code>package.json</code>.</p>
<p>After this, add to the <code><camera /></code> component <code>defaultOnFocusComponent={ true } onFocusChanged={ this.state.handleFocusChanged }</code> and <code>handleFocusChanged: () => {},</code> as an initial state</p> | 1 |

Are there any code samples for spring integration dsl error handling? | <p>The JmsTests.java was very helpful in understanding ways to structure my code. Code is at <a href="https://github.com/spring-projects/spring-integration-java-dsl/blob/master/src/test/java/org/springframework/integration/dsl/test/jms/JmsTests.java" rel="nofollow">https://github.com/spring-projects/spring-integration-java-dsl/blob/master/src/test/java/org/springframework/integration/dsl/test/jms/JmsTests.java</a> </p>
<p>But, for error handling, I am kind of figuring it out as we go. Are there any tests or reference code that show good ways to structure error channels or using sub-flows to delegate error handling? </p>
<p><strong>Adding more context to the question:</strong></p>
<ol>
<li>jmsMessageDrivenFlow: reads from incoming queue and prints payload. If there is an error, then it is sent to errorChannel()</li>
<li>handleErrors(): Is supposed to listen to errorChannel and send anything there to the fatalErrorQueue</li>
</ol>
<p>jmsMessageDrivenFlow() works fine and prints the message. I am expecting the error handler to be called only if there is an error during the jmsMessageDrivenFlow. However, the errorhandler() also gets called, and it puts a 'Dispatcher failed to deliver Message' message in the fatal queue. </p>
<p>I am hoping that the error channel shouldn't even be invoked in this scenario since jmsMessageDrivenFlow() didn't create any errors. Obviously, if I leave out .errorChannel(errorChannel()) in the jmsMessageDrivenFlow(), the error flow is not invoked and I get only jmsMessageDrivenFlow() executing as expected. </p>
<pre><code>@EnableIntegration
@IntegrationComponentScan
@Component
@Configuration

private static final Logger logger = LoggerFactory.getLogger(MessageReceiver.class);

How to sort array in alphabetical order without using Array.sort:Java | <p>I want to sort values of an array in alphabetical order in Java.I am stuck at going over the array again and get the output.

Boost asio non-blocking IO without callbacks | <p>Is it possible to use Boost's asio to do non-blocking IO <em>without using async callbacks?</em> I.e. equivalent to the <code>O_NONBLOCK</code> socket option.</p>
<p>I basically want this function:</p>
<pre><code>template<typename SyncWriteStream,
typename ConstBufferSequence>
std::size_t write_nonblock(
SyncWriteStream & s,
const ConstBufferSequence & buffers);

<blockquote>
<p>This function will write as many bytes as it can and return immediately. It may write 0 bytes.</p>

<p>Is it possible?</p> | 1 |
await GetByteArrayAsync in asp.net not returning | <p>The following code just hangs when called from an ASP.NET app:</p>
<pre><code>private async Task<XPathNavigator> UspsCreateAndPostRequest(string sUrl)
{
HttpClient client = new HttpClient();
byte[] urlContents = await client.GetByteArrayAsync(sUrl);
string sResponse = System.Text.Encoding.UTF8.GetString(urlContents);
... //more code to return XPathNavigator object based on response
}
</code></pre>
<p>If I change to following it works fine:</p>
<pre><code>private async Task<XPathNavigator> UspsCreateAndPostRequest(string sUrl)
{
HttpClient client = new HttpClient();
byte[] urlContents = null;
var task = Task.Run(async () => { urlContents = await client.GetByteArrayAsync(strUrl); });
task.Wait();
string sResponse = System.Text.Encoding.UTF8.GetString(urlContents);
... //more code to return XPathNavigator object based on response
}
</code></pre>
<p>Is the fact that method signature return is a Task<XPathNavigator> causing the issue? Thank you.</p> | 1 |
Does the "?." operator do anything else apart from checking for null? | <p>As you might know, <code>DateTime?</code> does not have a parametrized <code>ToString</code> (for the purposes of formatting the output), and doing something like</p>
<pre><code>DateTime? dt = DateTime.Now;
string x;
if(dt != null)
x = dt.ToString("dd/MM/yyyy");
</code></pre>
<p>will throw</p>
<blockquote>
<p>No overload for method 'ToString' takes 1 arguments</p>
</blockquote>
<p>But, since C# 6.0 and the Elvis (<code>?.</code>) operator, the above code can be replaced with </p>
<pre><code>x = dt?.ToString("dd/MM/yyyy");
</code></pre>
<p>which.... works! Why?</p> | 1 |

Is this the correct way to wrap readFileSync in a Promise | <p>The reason for the below code is to get rid of <code>callback hell</code>/<code>pyramid of doom</code>. I don't fully understand <code>i/o blocking</code> though yet.</p>

result = fs.readFileSync(fileName, 'utf8');
} catch (err) {
reject(err);
}
resolve(result);
});
console.log('result readFileSync: ' + str);

<p>All I'm expecting is a <code>yes</code> or <code>no</code> answer to be honest. Hope fully if no could someone give some details as I'm trying to learn properly about JavaScript sync/async and how to harness the power of Promises.</p> | 1 |

Calling Python functions/methods with zero arguments | <p>According to <a href="https://rads.stackoverflow.com/amzn/click/com/0132350882" rel="nofollow noreferrer" rel="nofollow noreferrer">Clean Code</a>, a function should take zero arguments when at all possible.</p>
<p>If we take a trivial example in Python with a function that does nothing more than add 2 to whatever is passed to it:</p>
<pre><code>def add_two(x):
return x + 2
>add_two(1)
3
</code></pre>
<p>The only way I can see that such a function can have zero arguments passed to it is by incorporating it into a class:</p>
<pre><code>class Number(object):
def __init__(self, x):
self.x = x
def add_two(self):
return self.x + 2
>n = Number(1)
>n.add_two()
3
</code></pre>
<p>It hardly seems worth the effort. Is there another way of achieving the no-argument function in this example?</p> | 1 |
Change .exe with hexeditor | <p>I wrote a little program in C++:</p>
<pre><code>#include <iostream>
int main()
{
int input;
std::cin >> input;
if(input == 5){
std::cout << "Input == 5";
}
else{
std::cout << "Input != 5";
}
return 0;
}
</code></pre>
<p>I have already built the program. The working program is in the <code>Release</code> folder. Now I want to change the <code>if</code> statement, without changing the C++ code. I downloaded a hex editor and opened the file. Inside the <code>.exe</code> is a lot. I googled for the problem and found this very nice image:</p>
<p><a href="https://i.stack.imgur.com/Q8mkC.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Q8mkC.png" alt=""></a></p>
<p>I searched inside the hex editor for my output <code>Input == 5</code>. I found it. When I change it to something different and execute the file, the program displays the new entered message, not the old one.</p>
<p><a href="https://i.stack.imgur.com/EKmw2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/EKmw2.png" alt=""></a></p>
<p>But now I want to change the structure of the code (the <code>if</code> statement). I searched for <code>if</code>, but didn't find anything. So, where is the <em>code section</em> (image)?</p> | 1 |
add and remove class on same button or element | <p>I'm looking for a way to add and remove class on the same button. So far this is my work in progress. The concept is when I click on the menu button it shows the menu. When I tap on the menu button again. The menu hides</p>

Illustrate mean and standard deviation in ggplot2 density plot | <p>I'm trying to construct a plot where I plot normally distributed variables showing their mean on the x-axis and the standard deviation (SD) on the y-axis. Kinda like a density plot, but instead of having the density on the y-axis I want to have the SD (value).</p>
<p>I'm working with the data below,</p>
<pre><code>set.seed(1)
mu1 <- rnorm(10^5, mean = 1, sd = 1)
mu3 <- rnorm(10^5, mean = 3, sd = 2)
</code></pre>
<p>two normally distributed variables. Here their mean and sd, </p>
<pre><code># install.packages("tidyverse", dependencies = TRUE)
require(tidyverse)
tibble(mu1, mu3) %>% summarise_all(funs(mean, sd))
#> # A tibble: 1 x 4
#> mu1_mean mu3_mean mu1_sd mu3_sd
#> <dbl> <dbl> <dbl> <dbl>
#> 1 0.9993454 3.000825 0.9982848 1.998234
</code></pre>
<p>I've played around with <a href="/questions/tagged/ggplot2" class="post-tag" title="show questions tagged 'ggplot2'" rel="tag">ggplot2</a>, and other <a href="/questions/tagged/tidyverse" class="post-tag" title="show questions tagged 'tidyverse'" rel="tag">tidyverse</a> packages, to get closer to what I want. I've also tried copying <a href="http://statistic-on-air.blogspot.com/2014/02/boxplot-with-mean-and-standard.html" rel="nofollow noreferrer">this function</a> from a box-plot doing something similar, having succeeded yet.</p>
<p>Here is my start,</p>
<pre><code>tibble(mu1, mu3) %>% gather() %>% ggplot() +
geom_density(aes(x = value, colour = key)) +
labs(x = 'mean', y = 'currently density, but I would like sd')

what's the difference of double in mysql and java? | <p>Have a table,</p>
<pre><code>CREATE TABLE `double_test` (
`price` double(11,2) DEFAULT NULL
)
</code></pre>
<p>and there are two records:</p>
<pre><code>select * from double_test;
+---------+
| price |
+---------+
| 1100.00 |
| 1396.32 |
+---------+
</code></pre>
<p>and sum them:</p>
<pre><code>select sum(price) from double_test;
+------------+
| sum(price) |
+------------+
| 2496.32 |
+------------+
</code></pre>
<p>And sum the two double in Java , </p>
<pre><code>System.out.println(1100.00 + 1396.32); //2496.3199999999997
System.out.println((1100.00 + 1396.32) == 2496.32); //false
</code></pre>
<p>So both are double why in mysql could get correct result?
and what's the difference of double type in mysql and java?</p>
<p>In java if use BigDecimal could get correct result, e.g.</p>
<pre><code> System.out.println(BigDecimal.valueOf(1100.00).add(BigDecimal.valueOf(1396.32)).equals(BigDecimal.valueOf(2496.32)));//true
</code></pre>
<p>Is actually double in mysql equal to BigDecimal in Java? </p> | 1 |
Terraform with Azure Marketplace | <p>I've started to get into <a href="https://www.terraform.io/" rel="nofollow">Terraform</a> and am loving it, since for cost reasons I have my services across a number of infrastructure providers, so it makes it easy to replicate full services without issues across IaaS providers.</p>

<p>So I need to select desired element from one of the groups (that should not be inactive, OK).<br>
When I'm selecting a group nothing occurs, no error and I don't see the the selected group opens.
Even for a moment.<br>
But when I'm trying to select an element in previously clicked group I receive </p>
<pre><code>org.openqa.selenium.ElementNotVisibleException: element not visible
</code></pre>
<p>error.<br>
So I understand that in the moment I'm clicking on desired element it is not visible since the group not appears open.<br>
But why?<br>
And what can I do to resolve this problem?<br>
Currently I'm using following code: </p>
<pre><code>String selectedGroup = getValue("group",'o');
String xpath1 = "//div[contains(text(),'" + selectedGroup + "')]";
driver.findElement(By.xpath(xpath1)).click();
webElement = driver.findElement(By.xpath(xpath1));
String className = webElement.getAttribute("class");
if(className.contentEquals("inactive"))
throw new ElementInactiveException("Selected group appears inactive. Exiting the test");
String optionAssetID = getValue("assetID",'o');
String xpath2 ="//div[@asset-id='" + optionAssetID + "']";
driver.findElement(By.xpath(xpath2)).click();
</code></pre>
<p>the error occur on the following line: </p>
<pre><code>driver.findElement(By.xpath(xpath2)).click();
</code></pre>
<p>When clicking on a Group or hovering over it it looks in the following way:<br>
As you can see from the code the selected / opened group receives "group-visible" class parameter. </p>

How to Create CaffeDB training data for siamese networks out of image directory | <p>I need some help to create a CaffeDB for siamese CNN out of a plain directory with images and label-text-file. Best would be a python-way to do it.<br>
The problem is not to walk through the directory and making pairs of images. My problem is more of making a CaffeDB out of those pairs.<br>
So far I only used <a href="https://stackoverflow.com/a/31431716/1714410"><code>convert_imageset</code></a> to create a CaffeDB out of an image directory.<br>
Thanks for help!</p> | 1 |

Bind or "connect" QUdpSocket to remote host and port? | <p>I would like to "connect" QUdpSocket to a remote host-port, but fail to do so. Is it possible?</p>
<p>The scenario I would like to implement is the following:</p>
<p>1) The server binds to localhost/port:</p>
<pre><code>// On server side, let server IP be "192.168.0.235"
serverUdpSocket->connectToHost(QHostAddress(QHostAddress::LocalHost), 44444);
... // check if connection is ok, etc
serverUdpSocket->write(someByteArray);
</code></pre>
<p>2) The client reads data from server, I tried:</p>
<pre><code>// bind fails with SocketAddressNotAvailableError
udpSocket->bind(QHostAddress("192.168.0.235"), 44444);
</code></pre>
<p>and this way:</p>
<pre><code>udpSocket->connectToHost(QHostAddress("192.168.0.235"), 44444, QIODevice::ReadOnly);
// State becomes "Connected", but I don't get any data and `readyRead()`
// is never emitted, though I connected to it.
</code></pre>
<p>but it doesn't work.</p>
<p>I know that UDP is a connectionless protocol. A also managed to do it vice versa - bind to local host and send data to this host from another. But I'm interested in this way of doing it, as remote host might be a server providing audio stream, that I want to read with my code.</p>
<p>In examples and tutorials I only see binding to local port and reading data from it. No examples with binding to remote host-port provided.</p> | 1 |

C code to check if command line is redirected to /dev/null | <p>I'm writing a C program that outputs to <code>stdout</code> and errors to <code>stderr</code>. The program takes a command such as:</p>
<pre><code>./myprogram function_to_run file_to_read
</code></pre>
<p>My program can either output to <code>stdout</code> or be directed to output a file, but it must not be redirected to <code>/dev/null</code>. For example:</p>
<pre><code>./myprogram function_to_run file_to_read //OK
./myprogram function_to_run file_to_read > file.txt //OK
./myprogram function_to_run file_to_read > /dev/null // NOT OK, should produce error in stderr
</code></pre>
<p>I tried to use <code>isatty(1)</code>, but it only can detect if <code>stdout</code> is outputting to a terminal. Therefore, it fails for the case where <code>stdout</code> is redirected to a file, which is acceptable in my case</p>
<p>Is there a way to check for this in C? If not, any suggestion how I could check for the /dev/null scenario?</p> | 1 |

<p>Now i don't understand how to continue in the JSP. I know i have to use the checkboxes tag, but i do not know what it returns on submit or if i use it correctly.</p>
<pre><code><form:form>
<form:checkboxes path="creams" items="${creams}"/>
<input type="Submit" value="Submit">
</form:form>
</code></pre>
<p>So the question is: What do I write in the JSP and what will be returned to the controller?</p>
<p>Added after comment:
IceCream class:</p>
<pre><code> public class IceCream{
private long id;
private String creamName;
</code></pre>
<p>//+getters/setters
}</p>
<hr>
<p>EDIT: After a helpful answer i tried this:
Adding those to the model: </p>
<pre><code>model.addAttribute("person", person);
model.addAttribute("creams", person.getCreams());
</code></pre>
<p>and in the JSP i did </p>
<pre><code><form:checkboxes path="teilnehmer"
items="${creams}"
itemValue="id"
itemLabel="creamName"
/>
</code></pre>
<p>So in the POST-Method i take a ModelAttribute Person.</p>
<p>added to Controller: </p>
<pre><code>@InitBinder
protected void initBinder(HttpServletRequest request, ServletRequestDataBinder binder) throws Exception {
binder.registerCustomEditor(IceCream.class, new IceCreamsPropertyEditor());
</code></pre>
<p>and the new Editor class:</p>
<pre><code>public class ContactsPropertyEditor extends PropertyEditorSupport{
@Autowired
IceCreamRepository creamrep;
@Override
public void setAsText(String text) throws IllegalArgumentException {
Integer creamId = new Integer(text);
IceCream cream = creamrep.findOne(creamId);
super.setValue(con);
}
}

Copy merged cells VBA | <p>I am trying to copy entire rows onto a new worksheet, but only copy those rows where a childs age is above 20.</p>
<p>I have not yet written the If statements to select these rows, but have written code to import the data and fill in various columns in order to get the 20th birthday from the birth date.</p>
<p>My problem is that the cells in the columns that are on the imported worksheet are merged. This is merged because one person may have more than one child, so in this case, the cells regarding the parent are merged. It won't let me copy the merged cells.</p>
<p>For now I'm just trying to work out how to copy the entire sheet just so I know how to copy merged cells, before doing the If statement.</p>
<p>This is what I have so far (bold bit at bottom is where I'm trying to copy merged cells. I'm getting an error on the line with ActiveSheet.Range("**").MergeArea.Copy</p>

Multiple Slim routes with the same signature | <p>We are looking at using Slim 3 as the framework for our API. I have searched SO and the Slim docs, but cannot find an answer to the issue. If we have different route files (e.g. v1, v2, etc.) and if two routes have the same signature, an error is thrown. Is there any way to cascade the routes so that the last loaded route for a particular signature is used?</p>
<p>For example, say v1.php has a route for <code>GET ("/test")</code> and v2.php also contains this route, can we use the latest version? Even simpler would be if a file of routes contains two routes with the same signature, is there a way of the latter method being used (and no error being thrown)?</p>
<p>A similar question is asked <a href="http://help.slimframework.com/discussions/questions/2634-overwrite-applied-routes-before-run" rel="nofollow">here</a> but this uses hooks (which have been removed from Slim 3 as per <a href="http://www.slimframework.com/docs/start/upgrade.html" rel="nofollow">here</a>)</p> | 1 |
Excel VBA loop through a string of numbers until a letter is found | <p>I have a string in a cell, lets say it says "Client Ref: F123456PassPlus".
It's possible the string not have a letter before the numbers, it's possible there is a symbol in the numbers and it's possible there is a space between the letter and the numbers.
I need to extract only the numbers as a variable. I have the code to do it, but it doesn't know when to stop looping through the string. It should stop when there is something other than a number or symbol but it carries on instead.</p>
<pre><code>IsNumber = 1
ref = ""
If branch = "" Then
e = b
Else
e = b + 1
End If
f = 1
While IsNumber = 1
For intpos = 1 To 15
ref = Mid(x, e, f)
f = f + 1
Select Case Asc(ref)
Case 45 To 57
IsNumber = 1
Case Else
IsNumber = 0
Exit For
End Select
Next
IsNumber = 0
Wend
</code></pre>
<p>Any variable letters there that don't have definitions have been previously defined, e tells the code where to start copying and x is the cell that contains the string. For now, it all works fine, it starts at the number and copies them and builds them into a bigger and bigger string, but it will only stop when intpos reaches 15.</p> | 1 |

Inline assembler: Pass a constant | <p>I have the following problem: I want to use the following assembler code from my C source files using inline assembler:</p>
<pre><code>.word 1
</code></pre>
<p>The closest I've gotten is using this inline assembler code:</p>
<pre><code>asm(".word %0\n": : "i"(1));
</code></pre>
<p>However, this results in the following code in the generated assembler file:</p>
<pre><code>.word #1
</code></pre>
<p>So I need a way to pass a constant that is known at compile time without adding the '#' in front of it. Is this possible using inline assembler?</p>
<p><strong>Edit:</strong></p>
<p>To make it more clear why I need this, this is how it will be used:</p>
<pre><code>#define LABELS_PUT(b) asm(".word %0\n": : "i"((b)));
int func(void) {
LABELS_PUT(1 + 2);
return 0;
}
</code></pre>
<p>I can't use ".word 1" because the value will be different every time the macro LABELS_PUT is called.</p> | 1 |

<p>I have:</p>
<ul>
<li>Added <code>crossOrigin="anonymous"</code> to the video element, but this just makes the video fail to load altogether</li>
<li>Tried even the same domain on a different port (as above)</li>
<li>Ensured that <code>Access-Control-Allow-Origin</code> is coming back with <code>*</code> (as above)</li>

Added code:</p>

var context = canvas.getContext("2d");
var w = video.videoWidth;

Laravel 5.2 Login Event Handling | <p>In the database I have a table users with column last_login_at. Everytime when some user logs in - I want to uptade <em>last_login_at</em>. </p>
<p>So, I created app/Listeners/<strong>UpdateLastLoginOnLogin.php</strong>:</p>
<pre><code>namespace App\Listeners;
use Carbon\Carbon;

<p>In app/Providers/EventServiceProvider:</p>
<pre><code> protected $listen = [
'auth.login' => [
'App\Listeners\UpdateLastLoginOnLogin',
],
];
</code></pre>
<p>BUT this doesn't work, event is not handled. The same problem has already been mentioned here: <a href="https://stackoverflow.com/questions/34974192/eventserviceprovider-mapping-for-laravel-5-2-login">EventServiceProvider mapping for Laravel 5.2 login</a> but without solution.

Jquery check for multiple classes (All must be present) in an element | <p>Hi I am trying to check if an element has the classes I am finding ex:</p>
<pre><code><span class="foo bar me"></span>
</code></pre>
<p>I want to check if the <code>foo</code> and <code>me</code> class is present on that element so I used this:</p>
<pre><code>$('body span').hasClass('me', 'foo')
</code></pre>
<p>this foo and me is stored in an array but this one didn't work:</p>
<pre><code>var arrayName = ['me', 'foo'];
$('body span').hasClass(arrayName)
</code></pre>
<p>the classes I am finding is dynamic that's why it is stored in an array, how can pass the dynamic array like the this one <code>'me', 'foo'</code> to the hasClass function?</p>
<p><strong><em>Note:</em></strong> the array can have 2-4 values in it.</p>
<p>I had my work here: <a href="https://jsfiddle.net/pcbttntk/" rel="nofollow">https://jsfiddle.net/pcbttntk/</a></p>
<p>Thanks in Advance.</p>
<p><strong><em>Update:</em></strong> <code>$('body span').hasClass('me', 'foo')</code> is not working, thanks to brett and Roko, it only checks the first class passed to it.</p> | 1 |

How to benefit from GPU with PYMC3 | <p>I see zero difference in PYMC3 speed when using GPU vs. CPU.</p>
<p>I am fitting a model that requires 500K+ samples to converge. Obviously it is very slow, so I tried to speed things up with GPU (using GPU instance on EC2).
Theano reports to be using GPU, so I believe CUDA/Theano are configured correctly. However, I strongly suspect that Pymc3 is not utilising GPU.</p>
<ul>
<li>do I need to set my variables to TensorType(float32, scalar) explicitly? Currently, they are float64.</li>
<li>Are only some samplers/likelihoods can benefit from CUDA? I am fitting Poisson-based model and so using Metropolis sampler, not NUTS</li>
<li>is there a way to check that pymc3 is using GPU?</li>

Realm not auto-deleting database if migration needed | <p>We are in development and db schema changes occur often. Since we are not live, migrations are not needed. I therefor configured Realm as follows:</p>
<pre><code>RealmConfiguration config = new RealmConfiguration.Builder(context)
.name("jt.realm")
.schemaVersion(1)
.deleteRealmIfMigrationNeeded() // todo remove for production
.build();
Realm.setDefaultConfiguration(config);
</code></pre>
<p>However, when the schema is changed, an exception is thrown: <code>RealmMigration must be provided</code></p>
<p>My understanding from the docs are that the Realm should auto-delete the db since deleteRealmIfMigrationNeeded() is present in the config, but this does not seem to be happening. Why is this occurring?</p>

Jacoco coverage for switch statement | <p>I am working to get 100% code coverage for a library I am working on and I seem to have some issues with a switch statement and the coverage which I simply don't understand.</p>
<p>I am currently using Jacoco 0.7.2 because every newer version seems to break with Robolectrics.</p>
<p>I test a simple switch statement:</p>
<pre><code>public enum Type {
NONE, LEGACY, AKS
}
private static Class<?> getCipherClass(Type type) {
switch (type) {
case LEGACY:
return CipherWrapperLegacy.class;
case AKS:
return CipherWrapperAks.class;
default:
return null;
}
}
</code></pre>
<p>The test I wrote contains the following checks (I have to use reflection as the method is private):</p>
<pre><code>final CipherWrapper instance = CipherWrapper.createInstance(mockContext, CipherWrapper.Type.LEGACY, ALIAS);
assertNotNull(instance);
Method getCipherMethod = TestUtils.makeMethodAccessible(CipherWrapper.class, "getCipherClass", CipherWrapper.Type.class);
assertNull(getCipherMethod.invoke(instance, CipherWrapper.Type.NONE));
assertEquals(CipherWrapperAks.class, getCipherMethod.invoke(instance, CipherWrapper.Type.AKS));
assertEquals(CipherWrapperLegacy.class, getCipherMethod.invoke(instance, CipherWrapper.Type.LEGACY));
</code></pre>
<p>The result is not what I have expected:</p>
<p><a href="https://i.stack.imgur.com/bVOE5.png" rel="noreferrer"><img src="https://i.stack.imgur.com/bVOE5.png" alt="Jacoco code coverage result"></a></p>
<p>The image is a bit confusing as the yellow line suggests that there is something missing. The green icon tells me that 3 of 3 branches are covered.</p>
<p>I also tested to extend the switch case with <code>case NONE</code> and a fall through but it didn't change anything.</p>
<p>The only thing I can do is to replace the switch with if/else and then I get 100% coverage.</p>
<p>Currently I have 98% coverage but I nothing is missed based on the overview:

Batch file to set a PowerShell variable | <p>For some reason i simply can't understand most of the sites who explain this question. So i'll try to ask here, if i'm am in the wrong place, just tell me in the comments and i'll put this in another forum and delete this question.</p>
<p>Let's say that i have 2 files, <code>Batch.bat</code> and <code>PowerShell.ps1</code>. </p>
<p><strong><em>Batch.bat:</em></strong></p>
<pre><code>set A="ThisIsSuchVar!"
</code></pre>
<p><strong><em>PowerShell.ps1:</em></strong></p>
<pre><code>$B = "Well, i don't know what to do here"
</code></pre>
<p>What can i do to the <code>B</code> variable be the same as the <code>A</code> variable?</p>

I've read <a href="https://stackoverflow.com/questions/29566343/create-a-new-column-in-a-r-dataframe-using-pattern-matching">this post</a>, but not getting the desired output. </p>
<p>I want to create a new column (SubOrder) based on the GreatGroup column.
I have tried the following: </p>
<pre><code>SubOrder <- rep(NA_character_, length(myData))
SubOrder[grepl("udults", myData, ignore.case = TRUE)] <- "Udults"
SubOrder[grepl("aquults", myData, ignore.case = TRUE)] <- "Aquults"
SubOrder[grepl("aqualfs", myData, ignore.case = TRUE)] <- "aqualfs"
SubOrder[grepl("humods", myData, ignore.case = TRUE)] <- "humods"
SubOrder[grepl("udalfs", myData, ignore.case = TRUE)] <- "udalfs"
SubOrder[grepl("orthods", myData, ignore.case = TRUE)] <- "orthods"
SubOrder[grepl("udalfs", myData, ignore.case = TRUE)] <- "udalfs"
SubOrder[grepl("psamments", myData, ignore.case = TRUE)] <- "psamments"
SubOrder[grepl("udepts", myData, ignore.case = TRUE)] <- "udepts"
SubOrder[grepl("fluvents", myData, ignore.case = TRUE)] <- "fluvents"
SubOrder[grepl("aquods", myData, ignore.case = TRUE)] <- "aquods"
</code></pre>
<p>For example, I'm looking for "udults" inside any word, such as Hapludults or Paleudults, and return just "udults". </p>
<p>EDIT: If anyone wants to take a shot at alistaire's comment, this is the search patterns I would use. </p>
<pre><code> subOrderNames <- c("Udults", "Aquults", "Aqualfs", "Humods", "Udalfs", "Orthods", "Psamments", "Udepts", "fluvents")
</code></pre>
<p>Example data below. </p>
<pre><code>myData <- dput(head(test))

Symfony2 send a POST request to an external API and parse its XML response? | <p>How to send a POST request to an external API and parse its XML response?</p>
<p>Normally using only php and xml I would do <a href="https://gist.github.com/gghhh456/d7ebc23c7c43a3697b74" rel="nofollow">something like </a>. But i am not sure how can I to do the same using Symfony.</p>
<p>Also please note that the content inside the xml file is dynamic like "Itemnumber", "quantity" etc</p>
<p><strong>Moreinfo:</strong></p>
<p>I am trying to send the xml data to our third party client system(they just work with XML so no JSON response) and parse this XML response and show it to our customers. Well since customer request are dynamic so does the contents inside the .xml file changes every-time. So i need to figure out</p>
<ol>
<li>Load this dynamic .xml file.</li>
<li>Make the connection using POST.</li>
<li>Read the Parse Xml data which i receive from our client(which can be done easily).</li>

Javascript - Adding new label and data to existing array | <p>As I know, it is possible to push more data into an array. Fe, I have an array: </p>
<pre><code>G = [12, 34, 5].
</code></pre>
<p>Right now, I can access the nth element like this: </p>
<pre><code>G[n]
</code></pre>
<p>I'd now like to push new data in it with a label, so I want the array to look like </p>
<pre><code>G = [12, 34, 5, label:567856, other: Infinity]
</code></pre>
<p>where I can get 567856 by calling </p>
<pre><code>G["label"] //(or Infinity by calling G["other"]). How can I achieve this?
</code></pre>
<p>I've found </p>
<pre><code>G[i].push({
label:567856,
other: Infinity
})
</code></pre>
<p>but this way it adds it as a whole new element, and I'm only able to call G[4]["other"], instead of G["other"]. How can I add the element as I've described?</p>
<p>Thank you!</p> | 1 |
