Managing Kitchen Fruit Flies with a Little Shop of Horrors

They congregate around the compost bin and the fruit bowl (where there are always lots of bananas). We aren’t slobbish - I do the dishes and wipe down the counters every night, take…

Diablo
All of us had become disappointed with computer RPGs because they were going in the opposite direction of where we thought they should be going. They were becoming story- and stat-laden, really appealing to a super-small niche of super RPG geeks — which we were in a way, but that wasn’t really our style.

Nanosecond timestamp collisions are common
I was wondering: how often do nanosecond timestamps collide on modern systems? The answer is: very often, like 5% of all samples, when reading the clock on all 4 physical cores at the same time. As a result, I think it is unsafe to assume that a raw nanosecond timestamp is a unique identifier.
