|
||
- *Tip (reprodcued from Chapter 5)*:
|
||
"Is there a really practical hands-on tip, an almost guaranteed way to become a kernel hacker? Of course, keep reading this book! Ha ha, yes, besides, do partake in the [simply awesome Eudyptula Challenge](http://www.eudyptula-challenge.org/). Hang on, it's - very unfortuantely, and as of this writing - closed down.
