AsyncTask threads never die
...xecution. How many will run at once is based on the number of cores of the CPU. AFAIK, the current algorithm is 2N+1 parallel threads, where N is the number of cores.

Microsecond timing in JavaScript
...lps me invalidate results that has probably been too adversely affected by CPU fluctuations).
It's become so accurate in some GPU accelerated browsers on i7 quad-core systems (when the browser window is the only window), that I've found I wished I could access a 0.1ms precision timer in JavaScript,...
How can I list the contents of a directory in Python?
...t have to os.path.isdir/file to know if it's a file or not, and that saves CPU time because stat is already done when scanning dir in Windows:
example to list a directory and print files bigger than max_value bytes:
for dentry in os.scandir("/path/to/dir"):
if dentry.stat().st_size > max_va...
Why is transposing a matrix of 512x512 much slower than transposing a matrix of 513x513?
...differ by a a multiple of 4096 have a false dependency on Intel SnB-family CPUs. (i.e. same offset within a page). This can reduce throughput when some of the operations are stores, esp. a mix of loads and stores.

...running the inner loop takes longer than that to fill the buffer, then the CPU will be the limiting factor. If the inner loop runs faster, then I/O will be the limiting factor, or at least there's some CPU time left over to do the real work.

Something like 'contains any' for Java set?
...nd set2 are very large, this would be plenty more resource intensive (both CPU and memory wise) than just checking if they have any item in common.

Set selected item of spinner programmatically
...e answer by Marco HC uses Runnable wich is a last resort due to additional CPU load. The answer is - you should simply choose correct place to call to setSelection(), for example it works for me:

super.onResume();
yourSpinner.setSelection(pos);
}

Convert Decimal to Double
