Re-learning C by reading K&R and operating systems by reading Tanenbaum et al in the evenings. Hoping to then read a bit deeper about operating systems and long-term dreaming of getting so deep (if I ever get there) that I can write/improve device support for an operating system. This is all with the end goal to feel less helpless when things work on one and not another, while not being best buddies with a BSD kernel hacker and almost certainly knowing that I lack the funds to hire one for the amount of hours necessary.
