Big list of http static server one-liners

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Business models based on the compiled list at http://news.ycombinator.com/item?id=4924647. I find the link very hard to browse, so I made a simple version in Markdown instead.

Git Branching Diagram Template

Git Branching Diagram Template for diagrams.net

This is my own variant of a git branching diagram template based on Bryan Braun's great template.

You can use this diagram as a template to create your own git branching diagrams. Here's how:

  1. Create a new diagram with diagrams.net (formerly draw.io)
  2. Go to File > Open From > URL
  3. Insert this url (it points to the xml data below): https://gist.githubusercontent.com/dornfeder/13abff279de357f048e474d4ed6c692d/raw/f5efc838bd34429e59e38063bd348b7a86457d18/git-diagram-template.xml
  4. Customize as needed for your team.
