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

Mermaid on Github Examples

All of these diagrams are dynamically rendered during html display by Github, the images generated from text inside the Github-Flavored Markdown. None are static images. Mermaid support was released for Github on 2022-02-14

Pros & Cons:

• Pro: You don't need to care about the layout.
• Con: You cannot control the layout.

Notes:

• Not all the features of Mermaid (in particular symbols B-->C[fa:fa-ban forbidden], hyperlink and tooltips) are supported by Github.

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.
