Hey all,

What the fish are CTFs? Capture The Flags are computer security competitions in which:

Contestants are presented with a set of challenges which test their creativity, technical (and googling) skills, and problem-solving ability. Challenges usually cover a number of categories (see below), and when solved, each yields a string (called a flag) which is submitted to an online scoring service. (Source: PicoCTF FAQ.)

OK, that was difficult reading. Here's an XKCD to make up for it:

Hey all,

If you haven't read the title by now, there's no CompSci meeting this week. Not that there would be one if you had read the title.

We hope y'all will have more time to study for your APs. In case you don't have one on Thursday or are just looking for some productive procrastination, here are some cool websites where you can interactively improve your CompSec skills, just in time for HSCTF:
