smontanaro / dusort.sh
Created November 7, 2022 11:01
I got this du postprocessing script from "the net" in the dark ages (probably from Usenet in the 80s or 90s). I have no idea who the original author was. I've never modified it **at all**. It has always just worked.
#!/bin/sh
#
# sort a "du" listing by directory size
# usage: du | dusort

dusort - sort du output to find biggest offenders
#!/bin/sh
#
# sort a "du" listing by directory size
# usage: du | dusort
# I found this on the net decades ago. It still works. I suppose it's "thank goodness" du(1)
# hasn't been "modernized".

Simple multi-threaded implementation of matrix multiplication in Python
#!/usr/bin/env python3
"""multi-threaded matrix multiply, demonstrating no-GIL benefits.
No help, crappy CLI. Run something like this:
python3 matmul.py NTHREADS SIZE
NTHREADS is (wait for it) the number of threads to spin up.
