39,397,548 | How to give non-root user in Docker container access to a volume mounted on the host | <p>I am running my application in a Docker container as a non-root user. I did this since it is one of the best practices. However, while running the container I mount a host volume to it <code>-v /some/folder:/some/folder</code> . I am doing this because my application running inside the docker container needs to write files to the mounted host folder. But since I am running my application as a non-root user, it doesn't have permission to write to that folder</p>
<p><strong>Question</strong></p>
<p>Is it possible to give a nonroot user in a docker container access to the hosted volume?</p>
<p>If not, is my only option to run the process in docker container as root?</p>

39,397,944 | javascript: a = b. Is it possible to change a but not influence b? | <p>Javascript Question. I am pretty new to javascript so pardon me if anything is not clear.</p>
<p>Please play following example at (right click) "inspect --> Console".</p>
<p>Example: </p>
<pre><code>o = [1,2,3];
y = o;
delete y[0];
y;// result: [undefined × 1, 2, 3]
o;// result: [undefined × 1, 2, 3]
</code></pre>
<p>Is it possible that the delete of <code>y</code> does not affect <code>o</code>? Here I made <code>y</code> equal to <code>o</code>. I just wanted to delete the first item of <code>y</code> but not <code>o</code>. However, <code>o</code> changes with <code>y</code> together. I wonder if it is possible to prevent <code>o</code> being changed even I change <code>y</code>?</p>

39,398,173 | 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>

39,400,886 | Docker cannot resolve DNS on private network | <p>My machine is on a private network with private DNS servers, and a private zone for DNS resolution. I can resolve hosts on this zone from my host machine, but I cannot resolve them from containers running on my host machine. </p>

39,400,997 | Angular 2 New Router: Change / Set Query Params | <p>I have a component registered at <code>/contacts</code>, which displays a list of contacts. I've added an <code><input [value]="searchString"></code> for filtering the displayed list.</p>
<hr>
<p>Now I'd like to display the <code>searchString</code> within the URL in form of a Query Param. (Using the New Router 3.0.0 RC2)</p>
<p>The official docs ( <a href="https://angular.io/docs/ts/latest/guide/router.html#!#query-parameters" rel="noreferrer">https://angular.io/docs/ts/latest/guide/router.html#!#query-parameters</a> ) show how to use <code>router.navigate</code> for changing the <code>queryParams</code>. But this seems awkward, because I just want to change the <code>queryParams</code> without having to know which route I'm currently at: <code>router.navigate(['/contacts'], {queryParams:{foo:42}})</code></p>
<p>(I know that it doesn't reload the component if I'm just changing the <code>queryParams</code>, but still this doesn't feel right to write)</p>
<hr>
<p>After some attempts I figured out that <code>router.navigate([], {queryParams:{foo:42}})</code> works. This feels way better.</p>

It mean that it can generate appropriate builds (makefiles, Visual Studio project etc.) based on instructions from CMakeLists.txt. But I do not understand two things which I guess are related:</p>
<ol>
<li><p>Why there are two buttons "Configure" and "Generate" in cmake-gui? In command line tutorials that I've read (e.g. <a href="http://derekmolloy.ie/hello-world-introductions-to-cmake/" rel="noreferrer">this one</a>) usual process was done with one <code>cmake</code> command.</p></li>
<li><p>What is cache in cmake world? AFAIK it is state when "Configure" button was pressed but "Generate" button was not pressed. But why is this useful? What all those variables that pops-up after pressing "Configure" mean? Why I'm supposed to edit them? Isn't the only allowed configuration done via CMakeLists.txt?</p></li>

39,401,504 | javascript/react dynamic height textarea (stop at a max) | <p>What I'm trying to achieve is a textarea that starts out as a single line but will grow up to 4 lines and at that point start to scroll if the user continues to type. I have a partial solution kinda working, it grows and then stops when it hits the max, but if you delete text it doesn't shrink like I want it to.</p>
<p>This is what I have so far.</p>
<pre><code>export class foo extends React.Component {
constructor(props) {
super(props);
this.state = {
textareaHeight: 38
};
}
handleKeyUp(evt) {
// Max: 75px Min: 38px
let newHeight = Math.max(Math.min(evt.target.scrollHeight + 2, 75), 38);
if (newHeight !== this.state.textareaHeight) {
this.setState({
textareaHeight: newHeight
});
}
}
render() {
let textareaStyle = { height: this.state.textareaHeight };
return (
<div>
<textarea onKeyUp={this.handleKeyUp.bind(this)} style={textareaStyle}/>
</div>
);
}
}
</code></pre>
<p>Obviously the problem is <code>scrollHeight</code> doesn't shrink back down when <code>height</code> is set to something larger. Any suggestion for how I might be able to fix this so it will also shrink back down if text is deleted? </p>

39,412,407 | git-stash changes without reverting | <p>I work on a project using Git. Every once in a while I find myself wanting to save my changes, without committing them, just as a backup, and then continue working. What I usually do is <code>git stash</code> and then immediately <code>git stash apply</code> to bring the code back to the same state as before stashing. The problem I have with this is that git stash reverts my work directory so even though I apply the stash immediately files and projects have to be rebuilt because they appear to have changed. This is quite annoying because some of our projects take ages to build.</p>
<p>So my question is, is there a way to stash my changes without reverting? If stash doesn't do that, is there any other command in git that can do it? Thank you.</p>

39,418,668 | C# Deserialize Multi-Dimentional JSON array | I am having an issue deserializing and defining this JSON structure would be great to get some assistance. I have reverted this back to last known working position because I am just going off the rails here.
my JSON stucture is:
[
{
"name": "Name1",
"description": "Description of this process",
"Location": "ANY",
"SubItems": [
{
"name": "sub1",
"required": true,
"description": "This is a short description"
},
{
"name": "sub2",
"required": true,
"description": "This is a short description"
},
{
"name": "sub3",
"required": true,
"description": "This is a short description"
}
],
"outputs": [
{
"name": "out1",
"required": false
},
{
"name": "exit code",
"required": false
}
]
},
{
"name": "Name2",
"description": "This is a short description",
"Location": "ANY",
"SubItems": [ {
"name": "sub1",
"required": false,
"description": "This is a short description"
}]
},
]
}
]
Here are my C# Json definitions that were last working.
public class JsonObject
{
[JsonProperty("name")]
public string ProcessName { get; set; }
[JsonProperty("description")]
public string ProcessDescription { get; set; }
[JsonProperty("Location")]
public string KnownLocation { get; set; }
}
I am only capturing a couple of definitions at the moment for testing.
Here is my deserializing object
var Object = JsonConvert.DeserializeObject <List<JsonObject>>(txt);
foreach (JsonObject JsonObject in Object)
{
Console.WriteLine("Name: " + JsonObject.ProcessName);
Console.WriteLine();
Console.WriteLine("Description: " +JsonObject.ProcessDescription);
Console.WriteLine();
}
So as I had stated, I can get at least the first 3 top-most level JSON elements in the output. The problem starts when I start trying to get the "SubItems" and "outputs"
I followed the structure of the below linked post and tried very hard to understand it, but after a while I realized that solution is not for this issue. I simply have a multi-dimentional array JSON object. Literally has a top tier, and 2 sub tiers
I attempted to try and do...
List<List<JsonObject>>Object = JsonConvert.DeserializeObject <List<List<JsonObject>>>(txt);
and tried to have 2 lists of the same with different names with 3 sets of JSON Definitions.
and implemented the tiered foreach loops, but then I wasn't able to access the definitions for the top most JSON, and nothing was writing for the actual elements for "SubItems"
What I need is to get to each object, really.

It runs perfectly on my computer. But when I tried to deploy using install shield limited(in debug build mode) to another computer, it shows the .exe file depends many .dll files. I had gone through google, found about dependency walker but when I run dependency walker it gives a dependency list with thousands of .dll files. It's time consuming manual process to copy each of the dll files from my computer and add it in the directory of the application. Is there any other better way to do this automatically? Is there anything I am missing during the building process or in the project property set up?

<p>I am using Match for handling provisioning profiles and certificates, it has been working beautifully so far.</p>
<p>I recently changed the bundle identifier, so created a new App Id in member center and reconfigured match etc. I have the development certificate and provisioning profile installed on my Mac. I have deleted the old certificates and the old provisioning profiles.</p>

<p>Its a simple scenario, based on the radio button selected, I want to attach a callback event using android data binding. I don't find any method on the xml part which allows me to define a callback.</p>
<p>Like here is my RadioGroup:</p>
<pre><code> <RadioGroup
android:id="@+id/split_type_radio"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:checkedButton="@+id/split_type_equal"
android:gravity="center"
<!-- which tag ? -->
android:orientation="horizontal">
...
</RadioGroup>
</code></pre>
<p>How do I attach a handler method which will be called on <code>RadioGroup</code>'s <code>checkChnged</code> event will fire using data-binding?</p>
<p>I have tried using <code>onClick</code> (don't know if it is the same) in layout file and defining method in the Activity and located it using this in the layout file:</p>
<pre><code> <variable
name="handler"
type="com.example.MainActivity"/>
...
<RadioGroup
android:onClick="handler.onCustomCheckChanged"
.. >
</code></pre>
<p>And defined method <code>onCustomCheckChanged</code> like this:</p>
<pre><code>public void onCustomCheckChanged(RadioGroup radio, int id) {
// ...
}
</code></pre>
<p>But, it gives me the compilation error:</p>
<blockquote>
<p>Error:(58, 36) Listener class android.view.View.OnClickListener with method onClick did not match signature of any method handler.onCustomCheckChanged </p>
</blockquote>
<p>I have seen many blogs mentioning it is possible with <code>RadioGroup</code> but non of them really say how. How can I handle this with <code>data-binding</code> ? </p>

<p>So given a Number, for example 12345, I must find out the sum sequence of the digits of the given number (1 + 2 +3 + 4 +5) and then add to it the result (15), and repeat this till the sum sequence of the last number is a digit (in this case is 6).</p>

<p>Thanks</p>

39,432,141 | Javascript array value as HTML src value | I'm a complete beginner to HTML and Javascript and I've encountered this problem. I have a button and under `onclick`, I have :
onclick="document.getElementById('slideCurrent').src=images[1]"
and in the Javascript portion, I have :
var images = [
"PATH BLABLABLA_1",
"PATH BLABLABLA_2",
"PATH BLABLABLA_3"
];
and for some reason, it won't display the image. However, if I put the path directly there, it will work normally.
What can I do to fix this?

39,432,717 | How can I cache external URLs using service worker? | <p>I've been playing with the Google Web Starter Kit (<a href="https://github.com/google/web-starter-kit" rel="noreferrer">https://github.com/google/web-starter-kit</a>) and have got a little progressive web app working but am stuck on one thing: caching static files from external CDNs. E.g. I'm using MDL icons from <a href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="noreferrer">https://fonts.googleapis.com/icon?family=Material+Icons</a> I can't see a way to cache the request as the service worker only responds to URLs within my app domain.</p>
<p>Options I see:
1. Download the file and put it in a vendor folder. Advantages: easy to set up SW cache. Disadvantages: file won't stay up to date as new icons are added (though that won't really matter as my code will only use the icons available).</p>
<ol start="2">
<li><p>Use the NPM repo: <a href="https://www.npmjs.com/package/material-design-icons" rel="noreferrer">https://www.npmjs.com/package/material-design-icons</a> and use build step to copy CSS file from node_modules. Advantages: will allow auto-updating from NPM. Disadvantages: slightly more complex to set up.</p></li>
<li><p>Some fancy proxy method that would allow me to use the SW to cache an external URL. e.g. myapp.com/loadExternal?url=<a href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="noreferrer">https://fonts.googleapis.com/icon?family=Material+Icons</a></p></li>
</ol>
<p>I'm leaning towards 2 right now but would be cool to know if 3 is possible.</p>

39,434,346 | React native takes very long to load on device | <p>I've been developing a react-native app using the simulator for a while. On the simulator (iOS), the app loads very fast (on reload for eg). However, when I tried to load the app to the device, it spends between 1-3 minutes in the splash screen before loading into the app. </p>
<p>My project is fairly small, and has no extra resources other than the javascript. Looking at the documentation I couldn't find what might be the cause of the issue, though I suspect it has to do with the fact that it is not getting the JS from the packager local server.</p>

39,435,443 | Why is Python 3 http.client so much faster than python-requests? | <p>I was testing different Python HTTP libraries today and I realized that <a href="https://docs.python.org/3/library/http.client.html" rel="noreferrer"><code>http.client</code></a> library seems to perform much much faster than <a href="http://docs.python-requests.org/en/master/" rel="noreferrer"><code>requests</code></a>. </p>
<p>To test it you can run following two code samples.</p>
<pre><code>import http.client
conn = http.client.HTTPConnection("localhost", port=8000)
for i in range(1000):
conn.request("GET", "/")
r1 = conn.getresponse()
body = r1.read()
print(r1.status)
conn.close()
</code></pre>
<p>and here is code doing same thing with python-requests:</p>
<pre><code>import requests
with requests.Session() as session:
for i in range(1000):
r = session.get("http://localhost:8000")
print(r.status_code)
</code></pre>
<p>If I start SimpleHTTPServer:</p>
<pre><code>> python -m http.server
</code></pre>
<p>and run above code samples (I'm using Python 3.5.2). I get following results:</p>
<p>http.client:</p>
<pre><code>0.35user 0.10system 0:00.71elapsed 64%CPU
</code></pre>
<p>python-requests:</p>
<pre><code>1.76user 0.10system 0:02.17elapsed 85%CPU
</code></pre>
<p>Are my measurements and tests correct? Can you reproduce them too? If yes does anyone know what's going on inside <code>http.client</code> that make it so much faster? Why is there such big difference in processing time?</p>

39,435,842 | JavaScript fetch API - Why does response.json() return a promise object (instead of JSON)? | <p>I've just started to learn the Fetch API: <a href="https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch" rel="noreferrer">https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch</a></p>
<p>Here's a code snippet which I wrote to tinker around with it:</p>
<pre><code>fetch('http://swapi.co/api/people/1')
.then(function(response) {
var json = response.json();
console.log(json);
// Expected : { "name": "Luke Skywalker","height": "1.72 m", ... }
// Get : Promise {[[PromiseStatus]]: "pending", [[PromiseValue]]: undefined}
});
</code></pre>
<p>I would have expected to get an JSON object out of response.json().</p>
<p>Similar to what you get when using JSON.parse(). </p>
<p>Instead I get a promise object. </p>
<p>If I enlarge the promise chain like shown here ... </p>
<pre><code>return response.json().then(function(json) {
// process your JSON further
});
</code></pre>
<p>... then it works: Within the then method of the following promise it appears as json.</p>
<p><strong>Why can't I retrieve the JSON data within the then() of the first promise?</strong></p>
<p>Can anyone please explain what is going on here?</p>
<p>I would really much appreciate it.</p>
