Just make Erlang to do some light-load task in a bunch of relatively short leaving processes. Calculating PI to 80th digit in batches per 10 procs with short, 8 ms, sleep in-between, to give schedulers a breath space, will do.
Run erl with 8 schedulers and no busy waiting on schedulers at all.

I've sniffed most of the Tinder API to see how it works. You can use this to create bots (etc) very trivially. Some example python bot code is here -> https://gist.github.com/rtt/5a2e0cfa638c938cca59 (horribly quick and dirty, you've been warned!)

| ### Shell script to download Oracle JDK / JRE / Java binaries from Oracle website using terminal / command / shell prompt using wget. | |
| ### You can download all the binaries one-shot by just giving the BASE_URL. | |
| ### Script might be useful if you need Oracle JDK on Amazon EC2 env. | |
| ### Script is updated for every JDK release. | |
| ### Features:- | |
| # 1. Resumes a broken / interrupted [previous] download, if any. | |
| # 2. Renames the file to a proper name with including platform info. |
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"
