How to refresh app upon shaking the device?
...er should be deactivated onPause and activated onResume to save resources (CPU, Battery).
The code assumes we are on planet Earth ;-) and initializes the acceleration to earth gravity. Otherwise you would get a strong "shake" when the application starts and "hits" the ground from free-fall. However,...
LinkedBlockingQueue vs ConcurrentLinkedQueue
... values by "busy waiting", for example, with the consumer thread eating up CPU.
So which one is "better" depends on the number of consumer threads, on the rate they consume/produce, etc. A benchmark is needed for each scenario.
One particular use case where the ConcurrentLinkedQueue is clearly bet...
Does Parallel.ForEach limit the number of active threads?
...P for any work that cannot be trivially reasoned about as being explicitly CPU bound.)

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
...using the user time from time(1).
Option #4 does have the additional memory overhead of adding a new item for every distinct key miss, so if you're e...

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...
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...
Why should you use an ORM? [closed]
...her options that solve the remaining problems with less learning and fewer CPU cycles.
Oh yeah, some developers do find working with ORM's to be fun so ORM's are also good from the keep-your-developers-happy perspective. =)

How can I profile Python code line-by-line?

Why do people say that Ruby is slow? [closed]
...h good. You'll
probably have to roll your own. But
sure, I'd like free CPU cycles too. I
just happen to care much more about
free developer cycles and am willing
to trade the former for the latter.
i.e. throwing more hardware or machines at the problem is cheaper than hiring more develop...
