Currently this defaults to 5 hours (based on [the code here][1]). 

You can override this by launching chrome with the `extensions-update-frequency` command-line parameter, which is the frequency in seconds. And you can go to `chrome://extensions`, tick the *Developer mode* checkbox at the top right, then press the *Update Extensions Now* button

[Chrome docs][3] doesn&#39;t specify this 5 hour value though, so it could change in future versions without notice:

&gt; *Every few hours*, the browser checks whether any installed extensions
&gt; or apps have an update URL. For each one, it makes a request to that
&gt; URL looking for an update manifest XML file.


  [1]: https://cs.chromium.org/chromium/src/extensions/common/constants.cc?q=kDefaultUpdateFrequencySeconds&amp;dr=CSs&amp;l=48
  [3]: https://developer.chrome.com/extensions/autoupdate

Restarting the browser and OS didn&#39;t help. Eventually, the extension updated itself, but it took at least 48 hours.

How do I repeat each element of a list `n` times and form a new list? For example:

    x = [1,2,3,4]
    n = 3
    
    x1 = [1,1,1,2,2,2,3,3,3,4,4,4]

`x * n` doesn&#39;t work

    for i in x[i]:
        x1 = n * x[i]

There must be a simple and smart way.

Repeating elements of a list n times

I was referring to Apple&#39;s Swift programming guide for understanding creation of Mutable/ immutable objects(Array, Dictionary, Sets, Data) in Swift language. But I could&#39;t understand how to create a immutable collections in Swift. 

I would like to see the equivalents in Swift for the following in Objective-C

**Immutable Array**

    NSArray *imArray = [[NSArray alloc]initWithObjects:@&quot;First&quot;,@&quot;Second&quot;,@&quot;Third&quot;,nil];

**Mutable Array**

    NSMutableArray *mArray = [[NSMutableArray alloc]initWithObjects:@&quot;First&quot;,@&quot;Second&quot;,@&quot;Third&quot;,nil];
    [mArray addObject:@&quot;Fourth&quot;];

**Immutable Dictionary**

    NSDictionary *imDictionary = [[NSDictionary alloc] initWithObjectsAndKeys:@&quot;Value1&quot;, @&quot;Key1&quot;, @&quot;Value2&quot;, @&quot;Key2&quot;, nil];

**Mutable Dictionary**

    NSMutableDictionary *mDictionary = [[NSMutableDictionary alloc]initWithObjectsAndKeys:@&quot;Value1&quot;, @&quot;Key1&quot;, @&quot;Value2&quot;, @&quot;Key2&quot;, nil];
    [mDictionary setObject:@&quot;Value3&quot; forKey:@&quot;Key3&quot;];

When I push a new version of a Chrome extension to the Chrome Web Store, how long will it take for the updated version to reach current users?

I pushed an update about six hours ago, but the extension hasn&#39;t updated for me yet. The Chrome docs are unclear.

How often do Chrome extensions automatically update?

Is there a feature in Google Chrome developer tools that would allow skipping a line without it being executed while debugging, in a similar way that it can be done in Visual Studio?

One workaround I can think of is &#39;live editing&#39; the code by wrapping the line in

    if(false){ //line to be skipped }

But this is not the most convenient workaround that I would have to do after every refresh. **Is there a built-in or faster, better way of doing this?**


Skip line while debugging in Chrome developer tools

I was helping a colleague debug some code today and I noticed a strange behavior with `console.log()` in Google Chrome:

It appears that if you:

1. Create a nested array (e.g., [[345,&quot;test&quot;]])

2. Log the array to the console with `console.log()`.

3. Modify one of the inner array values, then `console.log()` will output the later value -- **not** the values of the array at the time the `console.log()` was executed.

**JavaScript**:

    var test = [[2345235345,&quot;test&quot;]]
    console.log(test);
    test[0][0] = 1111111;
    // outputs: [[1111111,&quot;test&quot;]]
    
    var testb = {};
    testb.test = &quot;test&quot;;
    console.log(testb);
    testb.test = &quot;sdfgsdfg&quot;;
    // outputs: {&quot;testb&quot;:&quot;test&quot;}

    
    var testc = [&quot;test&quot;,&quot;test2&quot;];
    console.log(testc);
    testc[0] = &quot;sdxfsdf&quot;;
    // outputs: [&quot;test&quot;,&quot;test2&quot;]

**[JSFiddle Example][1]**

This behavior does not happen in Firefox.

Also to note, if I stepped through his code line by line in the Chrome debugger, then `console.log()` would output the correct values.

Is there an explanation for this strange phenomenon or is it just a bug with Google Chrome? 

**EDIT:**

I&#39;ve narrowed down the steps to reproduce the inconsistent `console.log()` behavior: 

If you add this script to your page:

    var greetings=[&#39;hi&#39;,&#39;bye&#39;];
    console.log(greetings);
    setTimeout(function(){
        greetings.push(&#39;goodbye&#39;);
    },3000);

and open it in a new window with the Chrome **console window already open**, then the `console.log()` output will be different than if you load the page with the **console window closed**. [Here&#39;s a JSFiddle that demonstrates that](http://jsfiddle.net/markasoftware/kcGkZ/).

In the first case, with the console window already open, `console.log()` will output the current value of the array (i.e., two items). 

In the second case, with the console window initially closed and opened only *after* the page loads, `console.log()` will output the later values of the array (i.e., three items). 

Is this a bug in Google Chrome&#39;s `console.log()` functionality?

Google Chrome console.log() inconsistency with objects and arrays

I am practicing JavaScript on Chrome&#39;s &#39;JavaScript Console&#39; ( version: 35.0) and I am unable to use the &#39;use strict&#39; clause as expected.

For the following code snippet :

    var obj={x:1,y:2}
    
    //Define new property with &#39;writable&#39; flag as false.
    Object.defineProperty(obj, &quot;z&quot;, {value:3, writable:false, enumerable:false, configurable:false})
    
    // Try to change the property &#39;z&#39;,
    &quot;use strict&quot;; obj[&quot;z&quot;]=4

&gt; Output: 4

As per my understanding, changing value of a &#39;non-writable&#39; property will silently fail in non-strict mode and throw &#39;TypeError&#39; in strict mode, But I don&#39;t see the exception.

    console.log(obj)

&gt; Object {x: 1, y: 2, z: 3}

Even though the property value is not changed but I am expecting a exception. 
Please correct if I am doing something wrong ?

I&#39;m trying to set cursor: pointer on a dom element, but the input isn&#39;t taking it (I am not seeing a pointer cursor when I hover over the checkbox). In chrome, I see that the &quot;user agent stylesheet&quot; is overriding my css. Wtf?

    &lt;!doctype html&gt;
    &lt;body&gt;
        &lt;div class=&#39;a&#39;&gt;
            &lt;input type=&#39;checkbox&#39;&gt;
        &lt;/div&gt;
    
        &lt;style&gt;
            .a {
                cursor: pointer;
            }
        &lt;/style&gt;
    &lt;/body&gt;

I have seen this question: https://stackoverflow.com/questions/11348727/why-does-user-agent-stylesheet-override-my-styles But my problem does not seem to be the doctype, which is [the recommended doctype][1]. 

Using `!important` isn&#39;t acceptable here, and neither is styling the input node directly - I shouldn&#39;t have to worry about weird browser useragent styles. What&#39;s going on?

To clarify, my question is about why the user agent stylesheet is overriding the css and how to make *that* stop. My question is *not* how I can hack around this behavior. If I&#39;m not mistaken, the correct behavior of css is that the cursor style should be inherited by child nodes.

Is this the expected behavior of css?

Ever since I upgraded to Postman 0.9.6 I can&#39;t replicate user sessions because chrome doesn&#39;t allow postman to get user cookies. However, they have decided to &quot;work around&quot; this issue by created another plugin called Postman Interceptor that routes your postman request and grabs the user cookies. They wrote a blog post about this wonderful tool here: http://blog.getpostman.com/index.php/2014/02/11/postman-v0-9-6-access-cookies-and-restricted-headers-plus-better-testing/

However, I can&#39;t seem to figure out how to get this thing to work. I have been trying for an hour now, and it still won&#39;t see my request as a logged in user

I&#39;m developing a Chrome extension and I need to store some data and then get it in some point. I did investigation on *available* `storage`s and came across to the following ones: `window.localStorage` and `chrome.storage.local`. 

So my question is, which one is the right choice to use in Chrome extensions:  
**`window.localStorage`** or **`chrome.storage.local`**?

*P.S.* I&#39;m using `browser action` to load a local `HTML` in `IFRAME`. So I&#39;m not using `popup.js`.

I&#39;m having an error running Chromecast sender in Chrome Incognito or if Chromecast extension is not installed:

Google cast sender is trying to send AJAX requests for local &quot;cast_sender.js&quot;. Should this happen or is there a better way to check if Chromecast sender extension exists (not by requesting AJAX request)?

I believe these AJAX requests are a way of asking if Chromecast extension exists. Is there a better way to check if Chromecast extension exists?

I have developed a Chrome extension and I have packed it.  
I sent my extension to some people to try it, but Chrome started to block extensions that it does not find in the store.

Is there any way to install my extension without getting blocked by Chrome?

**EDIT**  
Is there any way to install extension as developer mode? I read that only extensions that installed  in developer mode will not blocked.

How do I send a GET to `www.example.com` with the parameter `par` with value `0`?

What exactly are `process` and `update` in PrimeFaces `p:commandXxx` components and `execute` and `render` in `f:ajax` tag?

Which works at the time of validation? What does `update` attribute do rather than updating value to component from back end? Do `process` attribute bind value to model? What exactly do `@this`, `@parent`, `@all` and `@form` in both attributes?

The example below is working fine, but I am a little confused in basic concepts.
     
    &lt;p:commandButton process=&quot;@parent&quot;
                     update=&quot;@form&quot;

I&#39;m using spring-data&#39;s repositories - very convenient thing but I faced an issue. I easily can update whole entity but I believe it&#39;s pointless when I need to update only a single field:

    @Entity
    @Table(schema = &quot;processors&quot;, name = &quot;ear_attachment&quot;)
    public class EARAttachment {
    
        private Long id;
        private String originalName;
        private String uniqueName;//yyyy-mm-dd-GUID-originalName
        private long size;
        private EARAttachmentStatus status;


to update I just call method save. In log I see the followwing:

    batching 1 statements: 1: update processors.ear_attachment set message_id=100, 
    original_name=&#39;40022530424.dat&#39;, 
    size=506, 
    status=2,
    unique_name=&#39;2014-12-16-8cf74a74-e7f3-40d8-a1fb-393c2a806847-40022530424.dat&#39;
    where id=1 

I would like to see some thing like this:

    batching 1 statements: 1: update processors.ear_attachment set status=2 where id=1 

Spring&#39;s repositories have a lot of facilities to select something using name conventions, maybe there is something similar for update like updateForStatus(int status);

Is the same true for Firefox and Chrome? OR does update to service worker javascript only happens when user navigates to site?

Service worker JavaScript update frequency (every 24 hours?)

As far as I know, once you click &quot;add to homescreen&quot; on a PWA&#39;s website, the browser generates an .apk using the provided manifest file and sources and installs it like a normal app.

I noticed that when I update the website, the app also displays the updated content which suggests that the app is just a wrapper for accessing the website. I also noticed that the update to a website is not displayed instantly, I assume this is due to internal caching.

My question is, are my assumptions correct? Or more generally, when and how are PWAs updatated and is there a way to force an update on a client machine?
