Can Python test the membership of multiple values in a list?
...(range(50000))
>>> %timeit bigset >= bigsubset
1.14 ms ± 13.9 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
>>> %timeit all(x in bigset for x in bigsubset)
5.96 ms ± 37 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
Using subset testing is still fas...
Why does modern Perl avoid UTF-8 by default?
..., we got 12. Perl assumed that we were operating on the Latin-1 string "æååã" (which is 12 characters, some of which are non-printing).
This is called an "implicit upgrade", and it's a perfectly reasonable thing to do, but it's not what you want if your text is not Latin-1. That's why it's c...
Find nearest value in numpy array
...n. I wonder why it is so slow anyways. Plain np.searchsorted takes about 2 µs for my test set, the whole function about 10 µs. Using np.abs it's getting even worse. No clue what python is doing there.

Measure time in Linux - time vs clock vs getrusage vs clock_gettime vs gettimeofday vs timespec_get?
...r, hopefully not, wall-clock?)
What is the precision of the clock? (s, ms, µs, or faster?)
After how much time does the clock wrap around? Or is there some mechanism to avoid this?
Is the clock monotonic, or will it change with changes in the system time (via NTP, time zone, daylight savings time, ...
