I'm reading Apollo 13, and they mention John Aaron as being an amazing engineer who worked the EECOM (Electrical and Environmental Command) console. Trying to follow up more on who this guy was, I found very little on the Net. One of the interesting ideas he appears to have championed is to reduce the amount of human-computer interaction necessary for space flight. But, NASA appears to only carry bios of space spam (astronauts ;).
I started off reading about cars (wagons), moved to laptops and power consumption versus functionality, and then I realized that I don't really need either of those things. Now I'm reading about digital photography, as I'd like to (definitely not a need) be able to easily add a visual record to this journal. To gain some background awareness, DP Review has a great explanatory glossary for people like me.
