    http {
      server {
        location ~ /\.git {
          deny all;
        }
      }
    }

This `location` directive will deny access to any `.git` directory in any subdirectory.

**Note:** This location block must be before your main location block, so that it can be evaluated first.

Hidden directories and files should never be web accessible. The general answer to your question is: 

      location ~ /\.  { return 403; }

This denies access to .git, .svn, .htaccess and similar files in any subdirectory.

With other solutions I could download `/.git/config` and others, just `/.git` was protected. This one denies everything starting with a dot, regardless how deep the requested URL is:

    location ~ /\.(.*)/?(.*)? {
        return 404;
    }

This will prevent someone from hitting the http://example.com/.git but if your working in a subdirectory like this http://example.com/example/.git it will fail. You really need:


    location ~ .*/\.git {
        deny all;
    }



I&#39;m wondering is there any difference in performance of using CSS Transitions vs. any of the various JavaScript animation libraries? (`script.aculo.us`, `scripty2`, `jsAnim`, `MooTools`, `$fx`, etc).

I&#39;ve tried various tests in *Safari* and *Chrome* but I don&#39;t actually see any difference. I thought that CSS Transitions were supposed to be hardware accelerated.

--- 
**Update**:

I&#39;ve tried using Scriptaculous&#39; `Effect.Fade` on 5 different DIVs (each containing a canvas with some lines). Doing the exact same thing using CSS transitions, I see absolutely no difference in performance. Both were very smooth with one DIV/Canvas, but both are very slow when I do more than 2 at a time.

I&#39;ve tried this in *Safari 4, 5 (OSX)*, *Google Chrome 5* and *FireFox 3.7pre*. Same results across the board.

In answer to UpHelix&#39;s response, you&#39;re not simply limited to `hover`, etc. You can trigger a transition by changing any `transitionable` style. For instance, set the opacity of an element in JavaScript (after, you&#39;ve specified the `transitionPropery` and `transitionDuration` for that element).

I am trying to find a way to trim spaces from the start and end of the title string. I was using this, but it doesn&#39;t seem to be working:

    title = title.replace(/(^[\s]+|[\s]+$)/g, &#39;&#39;);

Any ideas?

I have several very large XML files and I&#39;m trying to find the lines that contain non-ASCII characters. I&#39;ve tried the following:

    grep -e &quot;[\x{00FF}-\x{FFFF}]&quot; file.xml

But this returns every line in the file, regardless of whether the line contains a character in the range specified.

Do I have the syntax wrong or am I doing something else wrong?  I&#39;ve also tried:

    egrep &quot;[\x{00FF}-\x{FFFF}]&quot; file.xml 

(with both single and double quotes surrounding the pattern).

I am trying to make simple regex that will check if a line is blank or not.

Assume I have a Regex pattern I want to match many Strings to.

    val Digit = &quot;&quot;&quot;\d&quot;&quot;&quot;.r

I just want to check whether a given String fully matches the Regex. What is a good and idiomatic way to do this in Scala?

I know that I can pattern match on Regexes, but this is syntactically not very pleasing in this case, because I have no groups to extract:

    scala&gt; &quot;5&quot; match { case Digit() =&gt; true case _ =&gt; false }
    res4: Boolean = true

Or I could fall back to the underlying Java pattern:

    scala&gt; Digit.pattern.matcher(&quot;5&quot;).matches
    res6: Boolean = true

which is not elegant, either.

Is there a better solution?

... means any character and the input is multiple lines.

I&#39;m trying to solve a gitignore problem on a large directory structure, but to simplify my question I have reduced it to the following.

I have the following directory structure of two files (foo, bar) in a brand new git repository (no commits so far):

    a/b/c/foo
    a/b/c/bar

Obviously, a &#39;git status -u&#39; shows:

    # Untracked files:
    ...
    #       a/b/c/bar
    #       a/b/c/foo

What I want to do is create a .gitignore file that ignores everything inside a/b/c but does not ignore the file &#39;foo&#39;.

If I create a .gitignore thus:

    c/

Then a &#39;git status -u&#39; shows both foo and bar as ignored:

    # Untracked files:
    ...
    #       .gitignore
    
Which is as I expect.

Now if I add an exclusion rule for foo, thus:

    c/
    !foo

According to the gitignore manpage, I&#39;d expect this to to work. But it doesn&#39;t - it still ignores foo:

    # Untracked files:
    ...
    #       .gitignore

This doesn&#39;t work either:

    c/
    !a/b/c/foo

Neither does this:

    c/*
    !foo

Gives:

    # Untracked files:
    ...
    #       .gitignore
    #       a/b/c/bar
    #       a/b/c/foo

In that case, although foo is no longer ignored, bar is also not ignored.

The order of the rules in .gitignore doesn&#39;t seem to matter either.

This also doesn&#39;t do what I&#39;d expect:

    a/b/c/
    !a/b/c/foo
That one ignores both foo and bar.


One situation that does work is if I create the file a/b/c/.gitignore and put in there:

    *
    !foo

But the problem with this is that eventually there will be other subdirectories under a/b/c and I don&#39;t want to have to put a separate .gitignore into every single one - I was hoping to create &#39;project-based&#39; .gitignore files that can sit in the top directory of each project, and cover all the &#39;standard&#39; subdirectory structure.

This also seems to be equivalent:

    a/b/c/*
    !a/b/c/foo
This might be the closest thing to &quot;working&quot; that I can achieve, but the full relative paths and explicit exceptions need to be stated, which is going to be a pain if I have a lot of files of name &#39;foo&#39; in different levels of the subdirectory tree.

Anyway, either I don&#39;t quite understand how exclusion rules work, or they don&#39;t work at all when directories (rather than wildcards) are ignored - by a rule ending in a /

Can anyone please shed some light on this?

Is there a way to make gitignore use something sensible like regular expressions instead of this clumsy shell-based syntax?

I&#39;m using and observe this with git-1.6.6.1 on Cygwin/bash3 and git-1.7.1 on Ubuntu/bash3.

While I found similar [question][1] I didn&#39;t find an answer to my problem

When I try to rename the directory from FOO to foo via `git mv FOO foo` I get  

    fatal: renaming &#39;FOO&#39; failed: Invalid argument

OK. So I try `git mv FOO foo2 &amp;&amp; git mv foo2 foo`

But when I try to commit via `git commit .` I get

    # On branch master
    # Untracked files:
    #   (use &quot;git add &lt;file&gt;...&quot; to include in what will be committed)
    #
    # foo
    nothing added to commit but untracked files present (use &quot;git add&quot; to track)

When I add the directory via `git add foo` nothing changes and `git commit .` gives me the same message again. 

What am I doing wrong? I thought I&#39;m using a case-sensitive system (OSX) why can&#39;t I simply rename the directory?

I have following working tree state

    $ git status foo/bar.txt
    # On branch master
    # Unmerged paths:
    #   (use &quot;git reset HEAD &lt;file&gt;...&quot; to unstage)
    #   (use &quot;git add/rm &lt;file&gt;...&quot; as appropriate to mark resolution)
    #
    #       deleted by us:      foo/bar.txt
    #
    no changes added to commit (use &quot;git add&quot; and/or &quot;git commit -a&quot;)

File `foo/bar.txt` is there and I want to get it to the &quot;unchanged state&quot; again (similar to &#39;svn revert&#39;):

    $ git checkout HEAD foo/bar.txt
    error: path &#39;foo/bar.txt&#39; is unmerged
    $ git reset HEAD foo/bar.txt
    Unstaged changes after reset:
    M       foo/bar.txt

Now it is getting confusing:

    $ git status foo/bar.txt
    # On branch master
    # Changes to be committed:
    #   (use &quot;git reset HEAD &lt;file&gt;...&quot; to unstage)
    #
    #       new file:   foo/bar.txt
    #
    # Changed but not updated:
    #   (use &quot;git add &lt;file&gt;...&quot; to update what will be committed)
    #   (use &quot;git checkout -- &lt;file&gt;...&quot; to discard changes in working directory)
    #
    #       modified:   foo/bar.txt
    #

The same file in both sections, new *and* modified? What should I do?

I develop a new website and I want to use GridFS as storage for all user uploads, because it offers a lot of advantages compared to a normal filesystem storage.

Benchmarks with GridFS served by nginx indicate, that it&#39;s not as fast as a normal filesystem served by nginx. 

[Benchmark with nginx](http://www.coffeepowered.net/2010/02/17/serving-files-out-of-gridfs/)

I understand thread driven that Apache uses: every connection opens up a thread and when the response is sent, the thread is closed, releasing the resources for other threads).

But I don&#39;t get the event driven design that Nginx uses. I&#39;ve read some basics about event driven design .. but I don&#39;t understand how this is used by nginx to handle web requests.

Where can i read and understand how Nginx is handling the connections in an event driven way so I get why it&#39;s better, rather than just accepting that event-based design is better than thread-driven design.

I get a 502 Bad Gateway with nginx when using spawn fcgi to spawn php5-cgi.

I use this to span an instance on server start using the following line in rc.local

presumably I&#39;m getting the error because the spawn-fcgi / php5-cgi dies and there is nothing listening there anymore to parse php.

I get nothing in the logs that I can see anywhere, I&#39;m out of ideas (and new to this setup with nginx)
