Why don’t SVG images scale using the CSS “width” property? | <h1>HTML</h1>
<pre class="lang-html prettyprint-override"><code><div id="hero">
<div id="social">
<img src="facebook.svg" alt="Facebook">
<img src="linkedin.svg" alt="LinkedIn">
<img src="instagram.svg" alt="Instagram">
</div>
</div>
</code></pre>
<h1>CSS using SASS</h1>
<pre class="lang-css prettyprint-override"><code>#hero {
display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
height: 300px;
#social {
width: 50%;
display: flex;
justify-content: space-between;
flex-wrap: wrap;
img {
width: 2em;
}
}
}
</code></pre>
<p>I’m not able to resize SVGs using the CSS <code>width</code> property. Here is what I obtain with different approaches (note how icons collapse toward the middle of the <code>hero</code> <code>div</code>):</p>
<p><code>img { width: 2em; }</code></p>
<p><a href="https://i.stack.imgur.com/7fIsb.png" rel="noreferrer"><img src="https://i.stack.imgur.com/7fIsb.png" alt="enter image description here" /></a></p>
<p><code>img { width: 3em; }</code></p>
<p><a href="https://i.stack.imgur.com/7iw0h.png" rel="noreferrer"><img src="https://i.stack.imgur.com/7iw0h.png" alt="enter image description here" /></a></p>
<p><code>img { width: 4em; }</code></p>
<p><a href="https://i.stack.imgur.com/Pbceu.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Pbceu.png" alt="enter image description here" /></a></p>
<p>However, if I use the CSS <code>height</code> property:</p>
<p><code>img { height: 2em; }</code></p>
<p><a href="https://i.stack.imgur.com/n10yp.png" rel="noreferrer"><img src="https://i.stack.imgur.com/n10yp.png" alt="enter image description here" /></a></p>
<p><code>img { height: 3em; }</code></p>
<p><a href="https://i.stack.imgur.com/B25nT.png" rel="noreferrer"><img src="https://i.stack.imgur.com/B25nT.png" alt="enter image description here" /></a></p>
<p><code>img { height: 4em; }</code></p>
<p><a href="https://i.stack.imgur.com/xcH8V.png" rel="noreferrer"><img src="https://i.stack.imgur.com/xcH8V.png" alt="enter image description here" /></a></p>
<p>I get the behaviour I need, but I’m not sure this is the right way. Why does this happen? Do you know better ways of resizeing SVG images (especially using the <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Flexible_Box_Layout/Basic_Concepts_of_Flexbox" rel="noreferrer">Flexible Box Module</a>)?</p> | 0 |
How to get .mp4 videos from motion on a Raspberry Pi? | <p>I use <a href="http://www.lavrsen.dk/foswiki/bin/view/Motion/WebHome" rel="noreferrer">motion</a> on my laptop and it works perfectly in any format. But when I use it on my Raspberry Pi 3 (Raspbian Jessie) with the Raspberry Camera V2, the only formats that work are : <code>.avi</code> and <code>.swf</code>.</p>
<p>When I choose any other format, the output video is a "0 sec video" that is played and closed instantly.</p>
<p>I would like to have <code>.mp4</code> or <code>.ogg</code> output so I can read it easily with HTML5.</p>
<p>Here is the <a href="http://www.lavrsen.dk/foswiki/bin/view/Motion/ConfigOptionFfmpegVideoCodec" rel="noreferrer">motion codec documentation</a>.</p>

Deepcopy in React | <p>In reducers,we always use <code>Object.assign({},state,newState)</code> to save a state. But <code>assign()</code> doesn't support deepcopy,because this method only copy a reference of multi-level object. This is my code in program.</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>const menuListState={
menuList: {},

<p>The property <code>menuList</code> is a multi-level Object. And when <code>action.data</code> changes, will <code>state.menuList</code> be changed immediately before the method <code>assign()</code> work?</p> | 0 |
Python -- Opening multiple tabs using Selenium | <p>I am using Python. I am trying to open two tabs on chrome, each to a different website. This is my code:</p>
<pre><code>from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
browser=webdriver.Chrome()
browser.get('http:/reddit.com')
browser.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 't')
time.sleep(3)
browser.get('http://bing.com')
</code></pre>
<p>When I run it, the first tab is opened to reddit.com, and then another tab opens to my default webpage, and then bing.com is opened in the original tab. I want the first tab to go to Reddit and the second tab to go to bing, but <code>browser.get('website')</code> only acts on the first tab.</p> | 0 |

React-native android WebView handle clicked Url before loading | <p>I'm showing a Website trough a WebView in react-native. On this Website there is a link to a PassWallet (.pkpass) file (not the only use case). When I click on any link on this Website I want to check whether it is an other Website or a .pkpass file or whatever. While this check is running I don't want to load anything, just wait until my function is finished and I'm knowing if I should open a Website or open another app or whatever. I want to make this on the JavaScript side because my whole routing functions are there and in my opinion react-native was built for this cases :-)</p>
<p>On iOS there is this beautiful function <code>onShouldStartLoadWithRequest</code> which exactly does what I need. </p>
<pre><code>_onShouldStartLoadWithRequest(e) {
if(checkUrl(e.url)) {
let Router = this.props.navigator.props.router;
let route = Router.getRouteFromUrl(e.url);
this.props.navigator.push(route);
return false;
}
return true;
}
</code></pre>
<p>I'm getting the event (e) and can check what url it's trying to load. I can even check with e.navigationType if it was a click or whatever. </p>
<p>Now on Android this function does not exists. On the native side there is the function <code>shouldOverrideUrlLoading</code> but this function is not implemented in react-native.
I found the following GitHub issue / PR <a href="https://github.com/facebook/react-native/pull/6478" rel="nofollow noreferrer">https://github.com/facebook/react-native/pull/6478</a>
I guess now, because this issue is closed and there are explanations for therefore, this function don't get implemented. </p>
<p>So I started to find a way by myself. I created a Native UI Component which displays a WebView and then implement this method.</p>
<p>CustomWebViewManager.java:</p>

import com.facebook.react.uimanager.annotations.ReactProp;
public class CustomWebViewManager extends SimpleViewManager<CplusWebView> {
@Override
public String getName() {
return "CplusWebView";
}
@Override
protected CustomWebView createViewInstance(ThemedReactContext reactContext) {
return new CustomWebView(reactContext);
}
@ReactProp(name = "url")
public void setUrl(CustomWebView view, @Nullable String url) {
view.loadUrl(url);
}
@ReactProp(name = "javascriptEnabled")
public void setJavascriptEnabled(CustomWebView view, boolean enabled) {
view.getSettings().setJavaScriptEnabled(enabled);
}
}
</code></pre>
<p>CustomWebView.java</p>
<pre><code>package ch.couponplus;
import android.util.Log;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import com.facebook.react.bridge.Arguments;
import com.facebook.react.bridge.ReactContext;
import com.facebook.react.bridge.WritableMap;
import com.facebook.react.uimanager.ThemedReactContext;
import com.facebook.react.uimanager.events.EventDispatcher;
import com.facebook.react.uimanager.events.RCTEventEmitter;
public class CustomWebView extends WebView {
EventDispatcher eventDispatcher;
EventWebClient eventWebClient;
public CustomWebView(ThemedReactContext reactContext) {
super(reactContext);
eventWebClient = new EventWebClient();
setWebViewClient(eventWebClient);
}
protected class EventWebClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
WritableMap event = Arguments.createMap();
event.putString("message", "MyMessage");
ReactContext reactContext = (ReactContext)getContext();
reactContext.getJSModule(RCTEventEmitter.class).receiveEvent(
getId(),
"topChange",
event);
return true;
}
}
}
</code></pre>
<p>It works as expected. I can now trigger the <code>shouldOverrideUrlLoading</code> function in JS and make logs or whatever. </p>
<p>But my question is how can I now set <code>true</code> or <code>false</code> in Javascript to control my <code>shouldOverrideUrlLoading</code> function? And is there a possibility to make my own functions available? Until now I only managed to trigger the <code>onChange</code> event? </p>
<p>I just want to make the same as I made in iOS. Maybe someone comes up and tells me that this isn't possible for whatever reason but how should I or how do you handle cases like this? I know there are Url schemas but so much I know they don't work in this case. </p> | 0 |
Error in y - ymean : non-numeric argument to binary operator randomForest R | <p>I have a matrix which is about 37k x 1024 consisting of 1s and 0s as categorical variables to indicate the existence or absence of a feature vector. I ran this matrix through the randomForest package in R as follows : </p>
<pre><code>rfr <- randomForest(X_train,Y_train)
</code></pre>
<p>Where X_train is the matrix containing the categorical variables and Y__train is a vector consisting of labels for every row in the matrix. When i run this, i get the following error : </p>
<pre><code>Error in y - ymean : non-numeric argument to binary operator
In addition: Warning message:
In mean.default(y) : argument is not numeric or logical: returning NA
</code></pre>
<p>I checked for any null values or missing data but didnt find any. </p>
<p>I even made the whole thing into a data.frame and tried the following</p>
<pre><code>rfr <- randomForest(labels ~ ., data = featureDF)
</code></pre>
<p>Still had the same errors. </p>
<p>I would appreciate any help with this, thanks!</p> | 0 |
TypeScript + Express : req.params | <p>I have the following express route :</p>

var idNum: number = Number(req.params.id);
var idCast: number = +req.params.id;
var id: number = req.params.id;
console.log('typeof idNum ', typeof idNum , ' ', 'idNum== 0 : ', idNum== 0 , ' ', 'idNum=== 0 : ', idNum=== 0);
console.log('typeof idCast', typeof idCast, ' ', 'idCast == 0 :', idCast == 0, ' ', 'idCast === 0 :', idCast === 0);
console.log('typeof id ', typeof id , ' ', 'id == 0 : ', id == 0 , ' ', 'id === 0 :' , id === 0);
res.json({});
});
</code></pre>
<p>this returns : </p>
<pre><code>typeof idNum number idNum== 0 : true idNum=== 0 : true
typeof idCast number idCast == 0 : true idCast === 0 : true
typeof id string id == 0 : true id === 0 : false
</code></pre>
<p>I understand that typescript provide only compile-time type-checking, and I guess it means it's not aware that req.params provide arguments as strings.</p>
<p>Is there any way I can automatically cast my params to Number ? or at least raise an error of I didn't done it manually ? Else, it seems that tympescript, unless used in a full-typescript environnement is useless.</p>
<p>Endly, is there any "big" open source project using TypeScript with ExpressJS that I could read the source from ?</p> | 0 |
Best practices for draining or clearing a Google Cloud pubsub topic | <p>For pubsub topics with number of messages in the range of ~100k, what is the best practice for draining/dropping/clearing/deleting all messages using gcloud-java SDK? </p>
<p>Possible solutions:</p>
<ul>
<li><p>Deleting and recreating the subscribers and then the publishers</p></li>
<li><p>High concurrency pull+ack (easy to hit the quota this way) </p></li>
<li>Something else</li>
</ul>
<p>My hope is that this process can be fast (not more than ~60 seconds, say), robust, and uses supported SDK methods with minimal other code.</p> | 0 |

Extract only quarter from a date in r | <p>I would like to extract ONLY the quarter from a date, e.g., to get an integer 1 from the date "2003-02-08". I have been trying something along this line</p>

Creating dynamic sitemap with php | <p>First let me tell you I am learning php. I want to create an automatically dynamic sitemap for my site. The script (suppose sitemap.php) will crawl all the links of my site and will create an array of 1000 urls. Once 1000 urls limit reaches, it will make an another page id with 1000 urls array. So that the script output will be like this :<br/></p>

How to remove an offline emulator from avd devices? | <p>I've created a couple of AVD-s in Android Studio. They were launching on emulator port 5554. Then I've created another AVD via <code>android avd</code> application, and they are starting on port 5556. </p>
<p>Now with a single emulator running, I get the following output from <code>adb devices -l</code>:</p>
<pre><code>List of devices attached
emulator-5556 device
emulator-5554 offline
</code></pre>
<p>I'm using the tooling which cannot supply the <code>-s</code> (specific device) option to <code>adb</code>, so when trying to install an app, I get an error:</p>
<pre><code>error: more than one device/emulator
</code></pre>
<p>And I'd like that there be a single connected emulator: the only one that I'm running.</p>
<p>I thought that removing the old Android Studio-created devices would do the trick of removing the emulator-5554, but nope. Even new devices created in Studio will open on 5556. So I've ended up with a forever-offline zombie <code>emulator-5554</code> that screws up my build tooling.</p>
<p>How can I force the new emulators to be run on port 5554 and/or remove the offline <code>emulator-5554</code>?</p>

<p>The problem is that this only exports the fields that do not have a template defined. (the first 3 in the grid below: Checkpoint, Location, Patrolled By), the other columns show up in the excel document, but the cells of those columns are all empty.</p>
<p>How can I get the values to show up in the excel export? I'm guessing it will require pre-processing of some sort before the excel gets exported, as the excel export function doesn't interpret my custom field html templates.</p>
<pre><code><div id="Checkpoints">
<div
...
data-toolbar='["excel"]'
data-excel='{ "fileName": "CheckpointExceptionExport.xlsx", "allPages": "true" }'
...
data-columns='[
{
"field": "checkpoint_name",
"title": "Checkpoint",
"filterable": { "cell": { "operator": "contains"}}},
{
"field": "location_name",
"title": "Location",
"filterable": { "cell": { "operator": "contains"}}
},
{
"field": "patrolled_by",
"title": "Patrolled By",
"filterable": { "cell": { "operator": "contains"}}
},
{
"field": "geotag",
"title": "GeoTag",
"template": kendo.template($("#geotagTemplate").html())
},
{
"field": "geofence",
"title": "GeoFence",
"template": kendo.template($("#geofenceTemplate").html())
},
{
"field": "completed",
"title": "Completed",
"template": kendo.template($("#completedTemplate").html())
},
{
"field": "gps",
"title": "GPS",
"template": kendo.template($("#gpsTemplate").html())
}
]'>
</div>
</div>
</code></pre>
<p>I've came across this snippet for handling the excel export event however I don't see a way to use this event handler in the way that I've defined the grid.</p>
<pre><code> <script>
$("#grid").kendoGrid({
excelExport: function(e) {
...
},
});
</script>

Jackson deserialize extra fields as Map | <p>I'm looking to deserialize any unknown fields in a JSON object as entries in a <code>Map</code> which is a member of a POJO.</p>
<p>For example, here is the JSON:</p>
<pre><code>{
"knownField" : 5,
"unknownField1" : "926f7c2f-1ae2-426b-9f36-4ba042334b68",
"unknownField2" : "ed51e59d-a551-4cdc-be69-7d337162b691"
}
</code></pre>
<p>Here is the POJO:</p>
<pre><code>class MyObject {
int knownField;
Map<String, UUID> unknownFields;
// getters/setters whatever
}
</code></pre>
<p>Is there a way to configure this with Jackson? If not, is there an effective way to write a <code>StdDeserializer</code> to do it (assume the values in <code>unknownFields</code> can be a more complex but well known consistent type)?</p> | 0 |
How do you test the content of a div or other element in enzyme/mocha/chai? | <p>I'm trying to verify that the content of a div matches what I'm expecting. What I have is:</p>
<pre><code>expect(wrapper.find('div.title').text().to.equal('A New Day');

<p>However, this isn't working for me. Is this possible in enzyme/chai/mocha? </p>

How to set the default language of date in R | <p>I used a R package written by other people. In the package, it is supposed to create a file name as "Mar.12". However the file name is "三月.12” in my system since I am running it on an OS with Chinese language (windows 10). I have changed the display language to English in the Rconsole file but it does not help. I am wondering is there any method to change the default date to English in R without revising the original package? </p>
<p>Thanks in advance for help!</p> | 0 |

Why are my Gradle builds dying with exit-code 137? | <p>I've been trying to compile and test a large project to use Gradle. The test run fine until they die unexpectedly.

need to the pagination show only number of pages (not items) and when swipe need to see the next 4 items( so swipe all 4 items and show next 4 items).</p>

Tensorflow: Using tf.slice to split the input | <p>I'm trying to split my input layer into different sized parts. I'm trying to use tf.slice to do that but it's not working.</p>
<p>Some sample code:</p>
<pre><code>import tensorflow as tf
import numpy as np
ph = tf.placeholder(shape=[None,3], dtype=tf.int32)
x = tf.slice(ph, [0, 0], [3, 2])
input_ = np.array([[1,2,3],
[3,4,5],
[5,6,7]])
with tf.Session() as sess:
sess.run(tf.initialize_all_variables())
print sess.run(x, feed_dict={ph: input_})
</code></pre>
<p>Output:</p>
<pre><code>[[1 2]
[3 4]
[5 6]]
</code></pre>
<p>This works and is roughly what I want to happen, but I have to specify the first dimension (<code>3</code> in this case). I can't know though how many vectors I'll be inputting, that's why I'm using a <code>placeholder</code> with <code>None</code> in the first place!</p>
<p>Is it possible to use <code>slice</code> in such a way that it will work when a dimension is unknown until runtime?</p>
<p>I've tried using a <code>placeholder</code> that takes its value from <code>ph.get_shape()[0]</code> like so: <code>x = tf.slice(ph, [0, 0], [num_input, 2])</code>. but that didn't work either.</p> | 0 |
How to use external Javascript function in Angular 2 template? | <p>I have a template in the component with 4 div tags.

Is ROWID in SQLite automatically set? | <p>So, I have this application on Ionic that uses the <a href="https://github.com/litehelpers/Cordova-sqlite-storage" rel="noreferrer">SQLite ngCordova plugin</a> for internal storage. On it, I create a table with the following command:</p>
<pre><code>db.executeSql(
"CREATE TABLE IF NOT EXISTS Scans_table (" +
//"id TEXT PRIMARY KEY NOT NULL," +
"name TEXT NOT NULL," +
"comment TEXT, " +
"text TEXT NOT NULL, " +
"format TEXT NOT NULL, " +
"dateTaken TEXT NOT NULL, " +
"imgSource TEXT NOT NULL)", ... );
</code></pre>
<p>According to <a href="https://www.sqlite.org/lang_createtable.html#rowid" rel="noreferrer">this</a>, if I don't have a column that is a primary key and an integer, a ROWID should be set as a unique identifier.</p>
<p>The problem is, when I query the table with a simple <code>SELECT * ...</code> I see all the rows that I set, and not the ROWID.</p>
<p>Is there a different way to set/check the ROWID?</p> | 0 |

Wildcards for directory in Windows batch command | <p>I need to copy the contents of a folder to another folder using a batch file - the problem I'm facing is that one of the parent folders will change every day, being named after today's date. So, for example, I have the following command:</p>
<pre><code>xcopy /Y /S "\\auto-jenkins\Builds\2017\R1\\[0822]\EN\\*.*" "C:\Users\Administrator\Desktop\EN"
</code></pre>
<p>This works fine today, unfortunately tomorrow the <code>[0822]</code> will not exist and the files I need will be under <code>[0823]</code>. Does anyone know of a way I can use a wildcard in place of <code>[0822]</code>?</p>
<p>The <code>[08**]</code> folder will be the only folder below <code>\R1</code> if that helps...</p> | 0 |

How to expose a Rust `Vec<T>` to FFI? | <p>I'm trying to construct a pair of elements:</p>

<p>All good, now I endup with another problem, example similar with may cases: on same controller I have two endpoints</p>
<ul>
<li>Post: /customer boddy: {email, location....}</li>
<li>Post: /customer/search boddy: {a filter, whatever}</li>
</ul>
<p>The example is not quite correct (last post should be a get) but still le assume that webapi cannot be changed (new controller for separation) for this particular case I will try to figure out a way to generate operationId diffrent for each action somehow, but my question is this: </p>
<blockquote>
<p>Is it possible to decorate somehow the controller actions similar with
[JsonIgnore] or with [Route("customer/delete")], to be explicit about the <strong>operationId</strong>. </p>

Property binding vs attribute interpolation | <p>I have read an article about difference between property and attribute bindings. From what I understood, most of the time, Angular2 prefers property bindings,
because after each change in data, the DOM would be updated. (If I am mistaken, please correct me).</p>
<p>I have a custom component and use it from the parent component. In it, I have an <code>@Input</code> named <code>truevalue</code>. when I initiate <code>truevalue</code> from the parent via property binding, sometimes, it does not change. I used following code:</p>
<pre><code><my-checkbox [(ngModel)]="chkItems" [disabled]="!editMode" [trueValue]="Y"></my-checkbox>
</code></pre>
<p>If I send <code>true</code> or <code>"1"</code> into <code>trueValue</code> it works, but If I send <code>"Y"</code> or <code>"YES"</code>, it does not work. So I am forced to use attribute binding. I don't know what is the problem.</p>
<p>I have changed it, into the following:</p>
<pre><code><my-checkbox [(ngModel)]="chkItems" [disabled]="!editMode" trueValue="Y"></my-checkbox>
</code></pre>
<p>Thanks in advance</p> | 0 |

How can I have multiple versions of the Java JDK installed on my machine at the same time? | <h1>Background</h1>
<p>I work mostly in Java and Scala on my job, but a lot of our legacy code has not yet been updated to the most recent JDK. Thus, we have to have JDK versions 5, 6, 7, and 8 installed on our development machines. Until recently, I had been using Arch Linux, but I just switched to OpenSuse Tumbleweed. The method I used to install the JDK versions was to download the RPM installer scripts from the Oracle website and install them beginning with 1.5 and working my way up to 1.8 so that the <code>/usr/java/latest</code> symbolic link would already be pointing to the correct version.</p>
<h1>Problem</h1>
<p>After reinstalling the aforementioned JDK versions, I attempted to point to these installations in IntelliJ IDEA. But it complained with the error "<a href="https://stackoverflow.com/questions/21713414/intellij-the-selected-directory-is-not-a-home-for-jdk">The selected directory is not a valid home for JDK</a>". I have found a lot of resources online concerning this issue and ones like it, but none of those solutions helped in my case. Furthermore, the symbolic links in <code>/usr/bin</code> for the sundry Java executables were pointing to a conflagration of <code>/etc/alternatives</code> directives.</p> | 0 |
Xamarin Forms - How to animate show/hide of item in StackLayout? | <p>I've got a Xamarin Forms cross-platform application (iOS and Android), and on one of the screens I want a list with details:</p>
<pre><code>Heading 1
Detail 1
Detail 2
Detail 3
Heading 2
Detail 1
Heading 3
Detail 1
Detail 2
</code></pre>
<p>As you can see, the amount of detail under each heading is variable.</p>
<p>I want the page to display at first with just the headings:</p>
<pre><code>Heading 1
Heading 2
Heading 3
</code></pre>
<p>And then when the user presses on a heading, the details for that particular heading appear. Pretty standard stuff.</p>
<p>I've tried several different ways to get this to work, the only path that seems open to me is to have a StackLayout where I define a bunch of labels:</p>
<pre><code>new StackLayout
{
Orientation = StackOrientation.Vertical,
Children =
{
new Label { Text = "Heading 1" },
new Label { Text = " Detail 1\n Detail 2\n Detail 3", IsVisible = false },
new Label { Text = "Heading 2" },
new Label { Text = " Detail 1", IsVisible = false },
new Label { Text = "Heading 3" },
new Label { Text = " Detail 1\n Detail 2", IsVisible = false }
}
}
</code></pre>
<p>I then add a TapGestureRecognizer to the heading labels, and when tapped I toggle the value of IsVisible for the detail labels. It works!</p>
<p>The only thing I don't like, is that there is no transition. I click on the heading label and BAM the detail label appears (correctly pushing down all the following labels to make space for itself). I would like an animation so that when I click on the header, the space beneath the header "slowly" opens up to reveal the detail.</p>
<p>As I read about animations online, one possibility is to set the HeightRequest of the detail labels to zero (instead of hiding them with IsVisible=false) and then creating an animation that "slowly" changes the HeightRequest from zero to the actual height of the label. And that's where I run into a problem.</p>
<p>I can't figure out how to get Xamarin to tell me the height of my "details" label.</p>
<p>If I inspect the Height and HeightRequest properties of my details label right after creating it, they are both -1 (no big surprise there). If I inspect those same two properties when I click on the heading, they are still -1. The only way I've found to get the height of my detail label, is to set the detail label visible, call ForceLayout() on my stack layout, store the detail label height, and then set the detail label invisible again. The problem with that is that I sometimes see the detail label flash visible for an instant while I do this.</p>

Xamarin Forms bind property to label's text | <p>I have Xamarin Forms xaml:</p>

<p>It should bind myProperty to label's text. However, nothing displays in the label. How to bind myProperty to label's text?

OData v4.0 aggregate queries (aggregate query syntax) | <p>For example,
I have an object model:</p>
<pre><code>Product

int ProductId,
string Name,
List<Sale> Sales

<ul>
<li>I want to use the aggregate queries to get total Amount of Sales:</li>
</ul>
<p><strong>GET: Product?$apply=groupby(Name, aggregate(Sales(Amount with sum as Total)))</strong> <em>(follow as oasis-open standard)</em></p>
<p>--> Got error: <em>UriQueryExpressionParser_CloseParenOrCommaExpected=" ')' or ',' expected at position {0} in '{1}'.</em> ". position at Amount.</p>

<li>I change the query to: </li>
</ul>
<p><strong>GET: Product?$apply=groupby(Name, aggregate(Sales/Amount with sum as Total))</strong></p>
<p>--> Work successfully!.</p>

What functions do Arrays in Google Apps Script support? | <p>I keep on finding that Array functions are missing in GAS, eg calling <code>find</code> gives the error: <code>Cannot find function find in object</code> </p>
<p>The only docs I can find on this are somewhat ambiguous:
<a href="https://developers.google.com/apps-script/guides/services/#basic_javascript_features" rel="noreferrer">https://developers.google.com/apps-script/guides/services/#basic_javascript_features</a></p>
<blockquote>
<p>Apps Script is based on JavaScript 1.6, plus a few features from 1.7 and 1.8. Many basic JavaScript features are thus available in addition to the built-in and advanced Google services: you can use common objects like Array, Date, RegExp, and so forth, as well as the Math and Object global objects. However, because Apps Script code runs on Google's servers (not client-side, except for HTML-service pages), browser-based features like DOM manipulation or the Window API are not available.</p>
</blockquote>
<p>How can I see what exact methods are available on Array?</p> | 0 |
HTTPS page was not allowed to run insecure content from safari-extension:// URI | <p>I face a strange behavior in a Safari extension with Safari 9.1 (11601.5.17.1). I try to insert a new Iframe with an src pointing to an html file in the extension package using "safari-extension://...".</p>
<p>The URL is correct and the content is displayed in a new tab, if I click on the link from the error message displayed in the console.</p>
<blockquote>
<p>[blocked] The page at https:// was not allowed to run
insecure content from
safari-extension://com.mycompany.myextension-7KZE138RQQ/3d4c3273/js/proxy.js.</p>
</blockquote>
<p>It seems the URL with safari-extension scheme is not considered as secured and safari applies "no http in https page" security policy.
It used to work before (before what? I don't know.).</p>
<p>Any idea? Could that behavior be changed with a specific Content-security-policy?</p>

Validating International Telephone Input using jquery validation | <p>Geeks!</p>
<p>We all know that awesome plugin called International Telephone Input,is there a way to tie it's own Validation method <code>intlTelInput("isValidNumber")</code> into jquery validation ?</p>
<blockquote>
<p><code>intlTelInput("isValidNumber")</code> returns <strong>true</strong> if true or <strong>false</strong> if false </p>
</blockquote>
<p>There is more details yet to come below!:</p>
<pre><code>var handleContactFormValidation = function () {
var value_form = $('#contact_form');//form i would like to validate where phone field is in!
var value_error = $('.alert-danger', value_form);
var value_success = $('.alert-success', value_form);
value_form.validate({
errorElement: 'span', //default input error message container
errorClass: 'help-block help-block-error', // default input error message class
focusInvalid: false, // do not focus the last invalid input
ignore: "", // validate all fields including form hidden input
rules: {
phone: {
required: {
depends: function () {
if ($(this).intlTelInput("isValidNumber") == true)
return true
else
return false
}
}
},
},
</code></pre>
<p>Now depending on the results "isValidNumber" method is returning i need to pass that validating Output {true,false} to the jquery validation but above is not functioning </p> | 0 |

Redshift: Executing a dynamic query from a string | <p>I would like to execute a dynamic SQL query stored in a string field on Amazon Redshift.</p>
<p>My background is mostly T-SQL relational databases. I used to build SQL statements dynamically, store them into variables and them execute them. I know Redshift can prepare and execute statements, but I wonder if it is possible to execute a query stored in a string field.</p>
<p>I have a piece of code that dynamically builds the code below with stats on several tables using pg_* system tables. Every column/table name is dynamically calculated. Here's an example of the query output:</p>
<pre class="lang-sql prettyprint-override"><code>SELECT h_article_id AS key, 'transport_parameters_weight_in_grams' AS col_name, COUNT(DISTINCT transport_parameters_weight_in_grams) AS count_value FROM dv.s_products GROUP BY h_article_id UNION ALL
SELECT h_article_id AS key, 'transport_parameters_width_in_mm' AS col_name, COUNT(DISTINCT transport_parameters_width_in_mm) AS count_value FROM dv.s_products GROUP BY h_article_id UNION ALL
SELECT h_article_id AS key, 'label_owner_info_communication_address' AS col_name, COUNT(DISTINCT label_owner_info_communication_address) AS count_value FROM dv.s_products GROUP BY h_article_id
</code></pre>
<p>I would like to input this dynamic piece of code within another query, so I can make some statistics, like so:</p>
<pre class="lang-sql prettyprint-override"><code>SELECT col_name, AVG(count_value*1.00) AS avg_count
FROM (
'QUERY ABOVE'
) A
GROUP BY col_name;
</code></pre>
<p>This would ouput something like:</p>
<pre><code>col_name avg_count
transport_parameters_weight_in_grams 1.00
transport_parameters_width_in_mm 1.00
label_owner_info_communication_address 0.60
</code></pre>
<p>The natural way for me to do this would be to store everything as a string in a variable and execute it. But I'm afraid Redshift does not support this.</p>
<p>Is there an alternative way to really build dynamic SQL code?</p> | 0 |
UnableToExecuteStatementException: Batch entry was aborted. Call getNextException to see the cause | <p>Using <code>@SqlBatch</code> to batch update the DB </p>
<pre><code>@SqlBatch("<SQL Command>")

<p>and I'm getting this error: </p>
<blockquote>
<p>org.skife.jdbi.v2.exceptions.UnableToExecuteStatementException:
java.sql.BatchUpdateException: Batch entry 0 ... was aborted. Call
getNextException to see the cause.</p>
</blockquote>
<p>The problem is the exception that's being caught is a <code>UnableToExecuteStatementException</code> and not the original <code>BatchUpdateException</code>, so I am unable to call <code>getNextException</code> to see the cause. Furthermore, I can run the SQL command in the DB directly just fine. </p>
<p>Any idea how to get to the bottom of the cause or what the issue might be?</p> | 0 |

jQuery: keyup event for mobile device | <p>I'm having a few issues getting a keyup event to fire on my iPhone, my code is as follows:</p>
<pre><code> var passwordArray = ["word", "test", "hello", "another", "here"];
var test = document.getElementById('enter-password');
test.addEventListener('keyup', function(e) {
if (jQuery.inArray(this.value, passwordArray) != -1) {
alert("THIS IS WORKING");
} else {}
});
</code></pre>
<p>The idea being that as the user is typing into the <code>#enter-password</code> field, as and when they've matched a word in the <code>passwordArray</code> the alert will fire. This works on desktop, e.g. once you've entered <code>word</code> the function will fire straight away as soon as you've typed the <code>d</code>. Is there anyway to get this to work for mobile too?</p> | 0 |
android-app link not working | <p>I'm following this example from Google I/O 2015.<br>

Injecting Dependency programmatically asp.net core | <p>I'm just starting with <code>Asp.net core</code> <em>Dependency Injection</em>, and my concept could be inaccurate. <a href="https://docs.asp.net/en/latest/mvc/controllers/dependency-injection.html" rel="nofollow noreferrer">This docs.asp.net post</a> explains how to inject context to a controller. I have little confusion regarding injection, in testing perspective. Assume we have following scenario:</p>
<pre><code>public interface ITasksRepository
{
public void Create();
}
//This is fake implementation, using fake DbContext for testing purpose
public class TasksRepositoryFake : ITasksRepository
{
public void Create()
{
FakeDbContext.Add(sometask);
//logic;
}
}
//This is actual implementation, using actual DbContext
public class TasksRepository : ITasksRepository
{
public void Create()
{
DbContext.Add(someTask);
//logic;
}
}
</code></pre>
<p>Now in order to inject context in controller, we design it as:</p>
<pre><code>public class TasksController : Controller
{
public ITasksRepository TaskItems { get; set; }
public TodoController(ITaskRepository taskItems)
{
TaskItems = taskItems;
}
//other logic
}
</code></pre>
<p>What asp.net <code>core</code> provides as builtin feature is, we can register the dependency injection in startup class as follows:</p>
<pre><code>public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddMvc();
services.AddSingleton<ITasksRepository, TasksRepositoryFake>();
}
</code></pre>
<p>According to this logic, my <code>TaskRepositoryFake</code> will be injected to the controller. So far, everything is clear. My questions/confusions regarding this are as follows:</p>
<p><strong>Questions:</strong></p>
<ul>
<li>How can I use this builtin DI feature to inject the context using some logic? May be programatically, or configuration based, or environment based? <em>(for example, always inject fake context, when using 'test' environment? etc.)</em></li>
<li>Is it even possible? If we always have to change this manually in <em>StartUp</em> class, then how does this builtin DI feature serve us? Because we could have simply done that in controller, without this feature.</li>

Laravel Query builder and table names | <p>I noticed that I write the database table names quite a lot, and in different files, when I use the Query Builder. If I were to change the database table names, I would have to search and change quite many rows in my project.
Is this an issue your Laravel guys noticed and come up with an solution to?</p>
<p>I like the Eloquent approach which uses class models, instead of database names; but for some queries I think the Query Builder is a better solution (though I am no expert in this matter).</p> | 0 |

Deep Merge using Lodash | <p>I have two arrays of objects that contain addresses that have a label and an object for the actual address:</p>
<pre><code>var originalAddresses = [
{
label: 'home',
address: { city: 'London', zipCode: '12345' }
},
{
label: 'work',
address: { city: 'New York', zipCode: '54321' }
}
];
var updatedAddresses = [
{
label: 'home',
address: { city: 'London (Central)', country: 'UK' }
},
{
label: 'spain',
address: { city: 'Madrid', zipCode: '55555' }
}
];
</code></pre>
<p>Now I want to merge these arrays by <code>label</code> and compare the individual properties of the addresses and merge only the properties from the new address that are actually present. So the result should look like this:</p>
<pre><code>var result = [
{
label: 'home',
address: { city: 'London (Central)', zipCode: '12345', country: 'UK' }
},
{
label: 'work',
address: { city: 'New York', zipCode: '54321' }
},
{
label: 'spain',
address: { city: 'Madrid', zipCode: '55555' }
}
]
</code></pre>
<p><strong>How can I do this using <a href="https://lodash.com/" rel="noreferrer">lodash</a>?</strong> I tried a combination of <code>unionBy()</code> and <code>merge()</code>. With unionBy() I was able to compare and join the arrays by label, but this always replaces the whole object. I can sure merge the addresses but this doesn't happen by label then.</p> | 0 |

ASP.NET Core Web API Authentication | <p>I'm struggling with how to set up authentication in my web service.
The service is build with the ASP.NET Core web api.</p>
<p>All my clients (WPF applications) should use the same credentials to call the web service operations. </p>
<p>After some research, I came up with basic authentication - sending a username and password in the header of the HTTP request.
But after hours of research, it seems to me that basic authentication is not the way to go in ASP.NET Core.</p>
<p>Most of the resources I found are implementing authentication using OAuth or some other middleware. But that seems to be oversized for my scenario, as well as using the Identity part of ASP.NET Core. </p>
<p>So what is the right way to achieve my goal - simple authentication with username and password in a ASP.NET Core web service?</p>
<p>Thanks in advance!</p> | 0 |

"_source": {
"animal": "bear",

<p>Later, you get this updated data about the bear:</p>
<pre><code>{
"color": "pink",
"weight": 500,
"diet": "omnivore",

<p>Using the Nodejs driver, what updateByQuery syntax would update the "bear" doc with these new values?</p>
