I posted an answer to this already when someone else asked the same question (see https://stackoverflow.com/questions/17871124/how-to-bring-back-browser-mode-in-ie11/17877416#17877416).

Read my answer there for a fuller explaination, but in short:

* They removed it **deliberately**, because compat mode is not actually really very good for testing compatibility.

* If you really want to test for compatibility with any given version of IE, you need to test in a real copy of that IE version. MS provide free VMs on http://modern.ie/ for you to use for this purpose.

* The only way to get compat mode in IE11 is to set the `X-UA-Compatible` header. When you have this and the site defaults to compat mode, you *will* be able to set the mode in dev tools, but only between edge or the specified compat mode; other modes will still not be available.


Situation
---------
I have two servers, Production and Development. On Production server, there are two applications and multiple (6) databases (MySQL) which I need to distribute to developers for testing. All source codes are stored in [GitLab](http://gitlab.org) on Development server and developers are working only with this server and don&#39;t have access to production server. When we release an application, master logs into production and pulls new version from Git. The databases are large (over 500M each and counting) and I need to distribute them as easy as possible to developers for testing.

Possible solutions
------------------

 *  &lt;strike&gt;After a backup script which dumps databases, each to a single file, execute a script which pushes each database to its own branch. A developer pulls one of these branches if he wants to update his local copy.&lt;/strike&gt;

    This one was found non working.

 *  Cron on production server saves binary logs every day and pushes them into the branch of that database. So, in the branch, there are files with daily changes and developer pulls the files he doesn&#39;t have. The current SQL dump will be sent to the developer another way. And when the size of the repository becomes too large, we will send full dump to the developers and flush all data in the repository and start from the beginning.

Questions
---------

 - Is the solution possible?
 - If git is pushing/pulling to/from repository, does it upload/download whole files, or just changes in them (i.e. adds new lines or edits the current ones)?
 - &lt;strike&gt;Can Git manage so large files?&lt;/strike&gt; No.
 - &lt;strike&gt;How to set how many revisions are preserved in a repository?&lt;/strike&gt; Doesn&#39;t matter with the new solution.
 - Is there any better solution? I don&#39;t want to force the developers to download such large files over FTP or anything similar.

Git with large files

I&#39;m using Chris Pine&#39;s Learn to Program and am stumped on his relatively simple challenge to take user input in the form of a list of random words and then alphabetize them in an array. Questions about this challenge have come up before, but I haven&#39;t been able to find my specific question on SO, so I&#39;m sorry if it&#39;s a duplicate.

    puts &quot;Here&#39;s a fun trick. Type as many words as you want (one per line) and 
    I&#39;ll sort them in...ALPHABETICAL ORDER! Hold on to your hats!&quot;
    wordlist = Array.new
    while (userInput = gets.chomp) != &#39;&#39;
       wordlist.push(userInput)
    end
    puts wordlist.sort

While this does the trick, I&#39;m trying to figure out how to alphabetize the array without case-sensitivity. This is hard to wrap my head around.
I learned about `casecmp` but that seems to be a method for comparing a specific string, as opposed to an array of strings.

So far I&#39;ve been trying things like:

    wordlist.to_s.downcase.to_a.sort!

which, in addition to looking bad, doesn&#39;t work for multiple reasons, including that Ruby 2.0 doesn&#39;t allow strings to be converted to arrays.

When I want to detect IE I use this code:

    function getInternetExplorerVersion()
    {
      var rv = -1;
      if (navigator.appName == &#39;Microsoft Internet Explorer&#39;)
      {
        var ua = navigator.userAgent;
        var re  = new RegExp(&quot;MSIE ([0-9]{1,}[\.0-9]{0,})&quot;);
        if (re.exec(ua) != null)
          rv = parseFloat( RegExp.$1 );
      }
      return rv;
    }
    function checkVersion()
    {
      var msg = &quot;You&#39;re not using Internet Explorer.&quot;;
      var ver = getInternetExplorerVersion();
    
      if ( ver &gt; -1 )
      {
        msg = &quot;You are using IE &quot; + ver;
      }
      alert( msg );
    }

But IE11 is returning &quot;You&#39;re not using Internet Explorer&quot;. How can I detect it?



How to detect IE11?

Do the F12 developer tools in Internet Explorer 11 also have the &quot;Always refresh from server&quot; feature of the developer tools in IE 8-10?

I see the &quot;Clear browser cache... (Ctrl + R)&quot; button on the [Network tool][1], but clicking on it appears to do nothing (the Temporary Internet Files folder still has files in it afterward). I also have the &quot;Check for newer versions of stored pages:&quot; setting set to &quot;Every time I visit the webpage&quot;, but this does not appear to always refresh external assets.

Can the cache be completely disabled in IE 11 for development?

For now I am just holding down the Ctrl key and clicking on the refresh button (per [Wikipedia&#39;s instructions to bypass the cache][2]), but this is easy to forget to do.

What happened to &quot;Always refresh from server&quot; in IE11 developer tools?

I have a simple web page with some Lipsum content that is centered on the page. The page works fine in Chrome and Firefox. If I reduce the size of the window, the content fills the window until it can&#39;t and then adds a scroll bar and fills content off screen, toward the bottom. 

However, the page doesn&#39;t center in IE11. I can get the page to center in IE by flexing the body, but if I do, then the content starts to go off screen towards the top and cuts off the top of the content.

Below are the two scenarios. See the associated Fiddles. If the problem isn&#39;t evident right away, reduce the size of the result window so that it&#39;s forced to generate a scroll bar.

Note: This application only targets the latest versions of Firefox, Chrome and IE (IE11), which all have support for the [Candidate Recommendation of Flexbox](http://www.w3.org/TR/css3-flexbox/), so feature compatibility shouldn&#39;t be an issue (in theory).


**Edit**: When using the Fullscreen API to fullscreen the outer div, all browsers correctly center using the original CSS. However, upon leaving the fullscreen mode, IE reverts back to being horizontally centered and vertically top aligned. 

**Edit**: IE11 uses non-vendor specific implementation of Flexbox. [Flexible box (&quot;Flexbox&quot;) layout updates][1]

Flexbox Not Centering Vertically in IE

When you scroll with the mouse wheel in Windows 8 the fixed background image bounces around like crazy. This only affects IE 10 and IE 11. This affects elements with `position:fixed` as well. 
Here is an example with a fixed background-image:

http://www.catcubed.com/test/bg-img-fixed.html

Here is example code:

    #section{
        position: fixed;
        top:0;
        left:0;
        background-color:#eee;
        background-position: top left;
        background-image: url(&quot;images/7.png&quot;);
        background-size: auto; 
        background-repeat: no-repeat;
        z-index: 10;
    }

Is there a solution to keep the background still in IE 10 and 11?


IE 10 &amp; 11 make fixed backgrounds jump when scrolling with mouse wheel

I&#39;m using the new [Internet&amp;nbsp;Explorer&amp;nbsp;11][1] developer tools to switch the document mode to &quot;8&quot;, but conditional comments are still ignored, that is, they are not properly parsed and behave like normal comments. So any referenced file inside the conditional comment is not requested/loaded by the browser.

Why does this happen? Is it a bug?

If you think that this is indeed a bug that needs to be fixed, please go in and say that you too can reproduce this on the Microsoft bug report that is reported for this issue:  
*[Conditional comments do not work when emulating document modes via F12 Developer Tools][2]*.

**Update:** This issue has been reported to be fixed in the mentioned bug report.

  [1]: http://en.wikipedia.org/wiki/Internet_Explorer_11#Internet_Explorer_11
  [2]: https://connect.microsoft.com/IE/feedback/details/806767/conditional-comments-do-not-work-when-emulating-document-modes-via-f12-developer-tools

Why doesn&#39;t Internet Explorer 11 honour conditional comments even when emulating Internet Explorer 8 document mode?

IE10+ no longer supports browser detection tags to identify a browser.

For detecting IE10 I am using JavaScript and a capability-testing technique to detect certain `ms` prefixed styles are defined such as `msTouchAction` and `msWrapFlow`.

I want to do the same for IE11, but I am assuming that all the IE10 styles will be supported in IE11 as well.  Can anyone help me identify IE11 only styles or capabilities that I could use to tell the two apart?

**Extra Info**

* I don&#39;t want to use User Agent type detection because it&#39;s so spotty, and can be changed, as well as I think I&#39;ve read that IE11 is intentionally trying to hide the fact it&#39;s Internet Explorer.
* For an example of how the IE10 capability testing works, I used this [JsFiddle][1] (not mine) as a basis for my testing.
* Also I am expecting a lot of answers of &quot;This is a bad idea...&quot;. One of my needs for this is that IE10 claims it supports something, but it is very badly implemented, and I want to be able to differentiate between IE10 and IE11+ so I can move on with a capability-based detection method in the future.
* This test is coupled with a Modernizr test that will simply make some functionality &quot;fallback&quot; to less glamorous behavior.  We are not talking about critical functionality.

**ALSO I am already using Modernizr, but it doesn&#39;t help here.  I need help for a solution to my clearly asked question please.**
