Using Ack with MySQL DESCRIBE TABLE
When using MySQL, you can use DESCRIBE TABLE to view the columns that a table contains; this is helpful for getting to know a table you're not familiar with, or to refresh your memory on a table you haven't seen in a while. However, sometimes, you're looking for a particular column in a long list (the table I used this on has over forty columns), and you have an idea on what the name of the column is. If you run into this situation, don't fret, and definitely don't strain your eyes looking through the list yourself! Let ack do the work for you:

Building Rakudo Perl 6 For Arch Linux
One of my favorite features of my Linux distribution of choice, Arch Linux, is its package manager and the ecosystem built around it. I maintain my own repository of packages; some are custom builds of packages available in the standard repositories (like Vim), others are packages that don't exist in the standard repositories at all. One of the packages I maintain is for Rakudo Star, a Perl 6 distribution. I encountered some troubles creating a pacman package for the September release of Rakudo Star. I thought I would share my experiences so other package maintainers could learn from them.

Making SSH_AUTH_SOCK Work Between Detaches in Tmux
I make heavy use of SSH agent forwarding in my workflow. However, sometimes you'll start a tmux session, do some work, and detach it.

I came up with a simple solution a while back; if you drop this in your .bashrc, it should just work:

Controlling MPD with Mac Media Keys
I use a Macbook Pro for my work at Booking, and I use music (or sometimes background noise) to avoid distractions while at work. However, I'm not a terribly big fan of iTunes; I much prefer the simplicity of MPD. My client of choice for MPD is Practical Music Search (pmus), which is curses-based and provides a nice shuffle feature. However, I want to avoid going back-and-forth between pmus and my work when I want to pause or skip tracks, so I managed to repurpose OS X's media keys to manipulate MPD and pmus. Here's how I did it.

Another Look At Perl 6
About once a year, when the planets align and I have enough free time, I usually check up on the Perl 6 community and see how things are going, trying to rekindle some enthusiasm for the language. Every year, I move away from Perl6 once again, either because my free time has dried up, or the synopses are too long to read, or I get angry about how they renamed STDOUT to $*OUT.
