TrueCrypt® is a multi-platform on-the-fly drive encryption tool. It allows you to encrypt all your data in a filesystem and still use everything normally. On Windows, it supports encrypting the system (boot) partition (or the entire boot drive); you can even make TrueCrypt® encrypt your existing partitions live and continue working (though the I/O performance sucks until it’s finished encrypting everything), pause and resume the encryption process (even across reboots). In short: it’s rather useful.

Even though TrueCrypt® introduced Windows system encryption in version 5.0 in February 2008 (that’s five months ago), its Linux version still doesn’t support accessing these encrypted partitions at all (it does mount “normal” TrueCrypt® volumes though). Since I recently encrypted my entire Windows drive but couldn’t live without the music files stored on it, I now humbly present the result of two wasted nights: a solution. (more…)

Today’s glance at reddit.com yielded a blog posting by a fellow who calls himself “Poromenos” and who recently wasted his day by designing a function made up of sines and cosines that encode the string “Hello world!”. “Hey”, I immediately thought, “I can do that too! I’m an expert at wasting my day, after all.” Only I decided to go a step further and write a program that generates this sort of function. I’m lazy, remember? (more…)

A few days ago, I posted a cheat sheet for Git (just as last time, Git is a really cool revision control system). Let’s face it: it was ugly. Not something you would actually hang up where other people could see it, was it? Here’s the remedy, which also works on both A4 and Letter and is more detailed. (more…)

Update: Since I first posted this, I have created a new and (in my opinion) better Git cheat sheet. You might want to have a look at that one.

Today I came across Zack Rusin’s Git cheat sheet (just so we’re on the same page: Git is a really good distributed revision control system). I quite like the idea but unfortunately, Zack’s design is fairly useless to me because

• the colors don’t print well on black and white;
• it’s designed for Letter paper. Letter paper doesn’t exist around here. Give me A4.

While trying to change Zack’s file to address these issues, Inkscape kept crashing on me until I finally gave up and just started from scratch (in – don’t tell anyone – OpenOffice.org Draw). This is the result: Git Cheat Sheet (A4 PDF version). (more…)
