| Celery worker blocks on rate limited task | |
| ========================================= | |
| by github.com/miraculixx | |
| Problem: | |
| If a worker has a rate_limit active on some task, and that task | |
| arrives (is received) more often than the rate limit interval, all | |
| worker processes will block on these task instances and stop | |
| consuming other tasks as soon as the prefetch count has maxed out |

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.
The script is here:
#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"
