That is a great idea, a series of programming exercises for the Linux kernel. I never needed to do kernel programming, but it always seemed terrible interesting to me. This will probably motivate me to actually do so!
I wonder if this is the work of Wolfgang "datenwolf" Draxinger. He's got the eudyptula.org domain and is perhaps most known for a talk at 27c3 that was completely derailed by Lennart Poettering.
I'm some levels in and this is amazing! You have to be actually motivated to make it and have a Linux machine around to go ahead, but I think it's run by some good kernel hackers.
0. Matasano challenge used a web interface, and it was quite pleasant. Doesn't really matter what the "view" is so long as the goal is accomplished. But if folks want to go down the boring cliché road of religulocity by insisting emacs is the only true editor[i], it would be disappointing.
[i] another example might be zsh vs. bash, a thread that would go off the right edge.
moving on up in complexity to getting patches accepted into the main Linux kernel source tree.
Any idea how many exercises are involved. I took a class on kernel modules, and this sounds like fun, plus it is moving towards something useful, and not just a set of exercises for learning's sake.
