You can use info command to get information 

for example: 

Open a terminal and type 

`bower info jquery-ui`

You will get a list of available versions as well

BTW: You can search via your terminal with:

    bower search jquery-ui

Try [**`bower-update`**](https://www.npmjs.com/package/bower-update). It will check for updates and allow you to update packages one-by-one.

From it&#39;s own description:

&gt; Updates Bower project’s components to the really latest versions, no matter what bower.json requires.

In case you are working with IntelliJ IDEA (or WebStorm), you can [use its bower plugin][1] to browse through through all available components find out their latest version:

It also offers a nice tabular view displaying current vs. latest versions of your installed components.

It&#39;s been a while since I used the Apache httpd web server.  I&#39;m firing up a local server for a project and when I try to request localhost/index.html, I get a 500 error and I see this in the error log:

    [Tue Jan 21 09:23:58 2014] [crit] [client ::1] configuration error:  couldn&#39;t perform authentication. AuthType not set!: /index.html
    [Tue Jan 21 09:23:58 2014] [error] an unknown filter was not added: DEFLATE
    [Tue Jan 21 09:23:58 2014] [crit] [client ::1] configuration error:  couldn&#39;t perform authentication. AuthType not set!: /favicon.ico

It looks like there are possibly 2 errors here in the apache config, one related to &quot;AuthType not set!&quot; and possibly another related to &quot;filter was not added: DEFLATE&quot;.  I dont know what these means or where to start digging in.  

A basic Google search revealed &lt;a href=&quot;http://boinc.berkeley.edu/dev/forum_thread.php?id=8603&quot;&gt;this link&lt;/a&gt; which indicates that the culprit may be &quot;Require all granted&quot;.  This line in my httpd.conf may be involved.

    &lt;Directory &quot;/var/www&quot;&gt;
        AllowOverride None
        # Allow open access:
        Require all granted
    &lt;/Directory&gt;

This apache config is mostly what is used in production for this project, so I know this works, just not currently on my workstation.  What does this mean and what should I try next?  I did try commenting out &quot;Require all granted&quot; and restarting apache but to no avail.

Following &lt;a href=&quot;https://stackoverflow.com/questions/18064060/django-with-mod-wsgi-on-apache-500-error-authtype-not-set&quot;&gt;this SO question&lt;/a&gt; I also loaded mod_authz_host

    LoadModule authz_host_module modules/mod_authz_host.so

and added &quot;Allow from all&quot;, restarted the server,. but the issue persists.  The deflate issue appears to be unrelated, and was easily solved by adding 

    LoadModule deflate_module modules/mod_deflate.so

The question remains, how do I solve this 500 error?

I would like to `await` on the result of `BlockingCollection&lt;T&gt;.Take()` asynchronously, so I do not block the thread. Looking for anything like this:

    var item = await blockingCollection.TakeAsync();

I know I could do this:

    var item = await Task.Run(() =&gt; blockingCollection.Take());

but that kinda kills the whole idea, because another thread (of `ThreadPool`) gets blocked instead.

Is there any alternative?

Is there anything like asynchronous BlockingCollection&lt;T&gt;?

Let&#39;s say I want to include the latest version of jquery-ui in my bower.json. Is there any way of finding out which versions are available? 

I see that I can find available components on http://sindresorhus.com/bower-components/#!/search/jquery-ui but there doesn&#39;t seem to be any mention of versions.

I&#39;m trying to install Bower on XUbuntu 13.10, following the instructions on the Bower home page, after doing `sudo apt-get install npm` and `sudo npm install -g bower` I get the following after issuing `bower` on the command line:

    /usr/bin/env: node: No such file or directory

I then install Node (even though I assume that would not be unnecessary since Bower&#39;s only dependency would be NPM, correct?). Anyhow, after I install node with `sudo apt-get install node` any of the Bower commands, such as `bower help`, simply don&#39;t do anything, i.e. output nothing.

How to install Bower on Ubuntu (preferably without manually downloading various versions of things)?


Installing Bower on Ubuntu

I am using Bower to install several libraries. For demonstration purposes here, I am installing bootstrap. Regardless of the package, I receive the following errors:

    C:\Scott&gt;bower install bootstrap
    bower not-cached    git://github.com/twbs/bootstrap.git#*
    bower resolve       git://github.com/twbs/bootstrap.git#*
    bower ECMDERR       Failed to execute &quot;git ls-remote --tags --heads git://github
    .com/twbs/bootstrap.git&quot;, exit code of #128

    Additional error details:
    fatal: unable to access &#39;https://github.com/twbs/bootstrap.git/&#39;: Failed connect
    to github.com:443; No error    

I have tried using the following solution to remove the first error - which I found from this [search][1]:
    
    git config --global url.&quot;https://&quot;.insteadOf git://

However, this does not work nor do any of the other solutions found on that page. Searching for a solution for the 2nd error, it seems that setting a username/pwd for a proxy server will resolve the issue if you are on a corporate network/behind a firewall. However, I am not using a proxy server as I am on my home pc/network (windows 7 x64).

Thanks!

Git / Bower Errors: Exit Code # 128 &amp; Failed connect

`bower install` behind a proxy fails in timeout with the following settings (some set are useless...) :

    git config --global http.proxy fr-proxy.example.com:3128
    git config --global https.proxy fr-proxy.example.com:3128
    
    export http_proxy=http://fr-proxy.example.com:3128
    export https_proxy=http://fr-proxy.example.com:3128
    
    npm config set proxy http://fr-proxy.example.com:3128
    npm config set https-proxy http://fr-proxy.example.com:3128
    
    npm config set registry http://registry.npmjs.org/

I have also tried an install/uninstall of bower and a `bower clean cache`.

bower behind a proxy

I am having huge problems trying to use bower (to install foundation 5) or get anything bower related to work on the command line.

I&#39;ve installed

 - ruby 1.9.3  
 - git (with run from command prompt option)
 - Nodejs

I&#39;ve successfully ran 

    npm install -g bower grunt-cli
    gem install foundation

and these have ran fine. I&#39;ve looked in the `npm/node_modules` directory and I can see `bower` folder in there.

Every time I type `bower` either into the `cmd`, `ruby cmd` or `git bash` I get
&gt; 
command not recognized

I&#39;ve set the git path in the environment variables.

What&#39;s annoying is the instruction on the bower site. It states:

    npm install -g bower
    bower install

Well this doesn&#39;t work!

bower command not found windows

I&#39;m trying to use Bower for a web app, but find myself hitting some sort of proxy issues:

    D:\&gt;bower search jquery
    bower retry         Request to https://bower.herokuapp.com/packages/search/jquery failed with ECONNRESET, retrying in 1.2s
    bower retry         Request to https://bower.herokuapp.com/packages/search/jquery failed with ECONNRESET, retrying in 2.5s
    bower retry         Request to https://bower.herokuapp.com/packages/search/jquery failed with ECONNRESET, retrying in 6.8s
    bower retry         Request to https://bower.herokuapp.com/packages/search/jquery failed with ECONNRESET, retrying in 15.1s
    bower retry         Request to https://bower.herokuapp.com/packages/search/jquery failed with ECONNRESET, retrying in 20.3s
    bower ECONNRESET    Request to https://bower.herokuapp.com/packages/search/jquery failed: tunneling socket could not be established, cause=Parse Error

Relevant points:
 
 - I can browse to https://bower.herokuapp.com/packages/search/jquery and it returns a full json response.
 - I can use git to clone, both using the git:// protocol and http(s).
 - I can use NPM directly without these issues
 - I&#39;ve tried using Fiddler to determine what&#39;s being blocked, but it doesn&#39;t detect any calls from the Bower command.  I can see calls from NPM commands in Fiddler.
 - I&#39;ve searched the Bower issues list, seen similar issues, but they either have no solution or it doesn&#39;t seem quite the same as mine.

Any ideas?
