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.
This may seem silly, but how do you send an email without html in the current version of Gmail?<p>One solution I think works is using m.gmail version (the mobile version). Is there any better way?
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.
<i>moving on up in complexity to getting patches accepted into the main Linux kernel source tree.</i><p>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.
I've been looking for an excuse for more C programming and less web dev. This seems like a great learning experience. Can't wait to start this!
