bash HISTSIZE vs. HISTFILESIZE?
... Look, my hard drive is 1 TB and largely empty, and I have gobs of idle CPU cycles and RAM, and I want to save as much bash history as reasonably possible -- so when I need to look up that stupid command I haven't run in two years, I know it's in my bash history. To make it more concrete, let's s...
Most efficient way of making an if-elif-elif-else statement when the else is done the most?
...e(1000000):
the_thing = options[something]
...and note the amount of CPU time they use...
1.py: 160ms
2.py: 170ms
3.py: 110ms
4.py: 100ms

Boost Statechart vs. Meta State Machine
...dware will be able to process a few hundred events per second.
Regarding CPU load, if the number of events to process is much lower than these numbers, Boost.Statechart overhead compared to MSM will almost certainly not be noticeable. If the number is much higher, you're definitely better off with...
Structs versus classes
