Learning and Maintaining a Large Inherited Codebase? 532

Posted by timothy from the bequeathed-and-devised dept.
An anonymous reader writes "A couple of times in my career, I've inherited a fairly large (30-40 thousand lines) collection of code. The original authors knew it because they wrote it; I didn't, and I don't. I spend a huge amount of time finding the right place to make a change, far more than I do changing anything. How would you learn such a big hunk of code? And how discouraged should I be that I can't seem to 'get' this code as well as the original developers?"

Tiny ARM-Based Sensor System Makes Battery Replacement Obsolete 96

Posted by timothy from the transcend-batteries dept.
An anonymous reader writes "University of Michigan researchers have crammed an ARM Cortex microcontroller, a thin-film battery, and a solar cell into a package that is only 9 cubic millimeters in volume. The system is able to run perpetually by periodically recharging the on-board battery with a solar cell (neglecting physical wear-out of the system)."

Considering the amount of energy required to emit high energy particles and the short distance they can travel outside a vacuum, shooting electrons and reading the radiation would not be a feasible option. This is not even considering introducing large amounts of radiation to the area which you are scanning. How about a giant fan with a bunch of light weight objects and they will run into the invisibility cloak revealing its position. Either than or non ionizing EM waves...

I have yet to see any problem, however complicated, which, when you looked at it in the right way, did not become still more complicated. -- Poul Anderson
