How can I print the contents of a hash in Perl?
... Also, benchmark before making claims about efficiency (or at least qualify the type of efficiency you are talking about). The for loop is faster than the while up to at least 10,000 keys: gist.github.com/151792

Nginx not picking up site in sites-enabled?
...y by having a single line with the relative path to the included file. (At least that's what it looked like in some "inherited" config files I've been using, until a new nginx version broke them.)
In sites-enabled/default (old config version?):
It seems that the include path is relative to the cur...
Store pictures as files or in the database for a web app?
...logy, I suggest you store images in SQL Server 2008 FILESTREAM columns (at least that's what I am going to do with my next project), since they combine the advantage of storing data in database AND having large binaries in separate files (at least according to advertising ;) )

How to compare two files not in repo using git
...rds outside a Git repository?
Shows how to use git to diff files where at least one of them is not in the repository by using --no-index:
git diff --no-index file1.txt file2.txt
It doesn't matter which one is tracked by git and which is not - one or both can be untracked, eg:
$ date > x

What is the C runtime library?
... stored together into one bigger file. The archive will usually contain at least some indexing to make it relatively fast/easy to find and extract the data from the internal files. At least at times, Microsoft has used a library format with an "extended" index the linker can use to find which functi...

What does dot (.) mean in a struct initializer?
...
There is a potential gotcha in dot initialization (at least with some compilers). struct demo_s demo = { .first = 1, .first = 9 }; On one of my GCC this will compile without warning and first will be 9.

Are nested HTML comments possible?
... how many comments are represented by the above tag pollution, but it's at least 10.
I got less lazy: This so-called "comment" actually consists of 10 comments,
three words outside any comment (i.e., just bad SGML), and the
beginning of a comment that is not terminated. It's a real mess:
