How to create gists from the command line

I was a bit astonished that I couldn't find a working example written in bash on the net that would create gists on the github from the command line. Some examples didn't work at all because they were using old github API or because the text escaping weren't properly implemented. The rest didn't have the functionality I needed.

Sound volume change notifications using pynotify

As I started to use the i3 window manager I wanted to have a visual feedback on sound volume change events. Usually it's done by a daemon that binds to specific keyboard combinations to adjust volume and to send notifications to a notify daemon. In xfce this is done by the xfce4-volumed. I should also point here to other lightweight volume daemons like volnoti or pa-applet. Without a dedicated daemon it is also pretty much simple to handle sound volume keys by a simple bash script which is bind to specific keyboard combinations.

Javascript vs Perl vs Python vs Lua speed comparison

I have previously compared performance of the three most popular interpreted languages - Perl, Python and Lua (part1, part2). The next question was - how do they compare to the Javascript? Unlike the above mentioned languages it was quite unusual to use Javascript outside of a browser sandbox but with developing of the node.js this became possible.

Python vs Perl vs Lua - speed comparison. Part 2

As far as people show interest in this topic I decided to perform an additional measurement to the one I performed in Part 1.

This time I wanted to compare floating point numbers operations performance because my good friend Anonymous worried about it. He said that I shouldn't have abused lua interpreter with basic arithmetic operations on integers because it's not good at it. He said that I should have tried floating points numbers instead to let lua interpreter shine. I was a bit skeptic about it to be honest but Anonymous's logic was sound.

Python vs Perl vs Lua - speed comparison

I have written the base64 encoding algorithm in Perl, Python and Lua to compare the performance in basic arithmetic and file-io operations. Perl implementation was written a long time ago and it supposed to be a one liner. That's why the script looks so obfuscated:
