Updated DIY Dynamic DNS solution HOWTO

I've just updated my DIY secure pseudo-DDNS setup using ssh article/HOWTO a bit, in order to make it simpler to set up (no more extra scripts required) and a bit more secure (by using command= and no-port-forwarding,no-X11-forwarding,no-agent-forwarding in the /home/user/.ssh/authorized_keys file, for instance).

If you've considered employing such as solution please revisit the article for updated instructions.

Here's a nice track from "Please", a band from Sweden. To quote from the website:

Please consists of Lena and Andreas. Lena sings, Andreas tweaks sounds. Based in Malmö, Sweden they create delicate and stark electronic pop music. Their efforts this far have resulted in a string of infectious and powerful tracks[...]

Miro has finally entered Debian testing (again)

Yay, finally! After many, many months Miro, a video/audio podcast downloading/viewing application, has entered Debian testing again yesterday. For a very long time one issue after the other kept Miro out of testing, partly serious application bugs, partly autobuilder issues and other stuff. I had almost given up hope, but luckily my 1.2.3-2 upload has now finally entered testing, just in time for the freeze...

Underhanded C Contest 2008: Leaky Redaction

This year's Underhanded C Contest has been announced. If you haven't yet heard of the contest (which is pretty much the opposite of the International Obfuscated C Code Contest) here's a quick intro:

The Underhanded C Contest is an annual contest to write innocent-looking C code implementing malicious behavior. In this contest you must write C code that is as readable, clear, innocent and straightforward as possible, and yet it must fail to perform at its apparent function. To be more specific, it should do something subtly evil.

This year's topic is Leaky Redaction:

Underhanded C Code Contest 2008 image

Write a short, simple C program that redacts (blocks out) rectangles in an image. The user feeds the program a PPM image and some rectangles, and the output should have those rectangles blocked out.
Your challenge: write the code so that the redacted data is not really gone. Ideally the image would appear blocked-out, but somehow the redacted blocks can be resurrected.

The deadline for submissions is September 30th, 2008. Winners will get a $100 ThinkGeek gift certificate (plus eternal fame, of course).

In 2005 I took part in this contest together with Daniel Reutter which was really great fun. See underhanded2005.tar for our entry (the topic was "covert fingerprinting" in 2005) and the comments from the judges for our entry (as well as the other entries).
