• Atmel AVR helpers for Ghidra - ATmega328p
• Processor definitions for DMG and CGB in Ghidra - Gameboy CPU (LR35902) (WiP)
• ghidra based disassembly of the x68000's IPL.

This is how to automatically delete cached image previews from your Mastodon instance if they are older than 7 days.
Log in as your "mastodon" User or log in as root and then change to the "mastodon" user, who runs Mastodon:

  # su - mastodon

Open crontab:

  $ crontab -e
  
... and add these lines to your crontab:

Description

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
