Musings on technology.
The Terminal on macOS offers quite an amount of functionality, but most of it is hard to discover unless you already know what you’re looking for. So here’s a quick cheat sheet explaining unique functions with their corresponding key combos: Marks Marks allow you to mark certain lines in the output, and allow you to jump between different parts of the output. By default, every time you hit enter…

One feature of any shell that is immensly useful is the history. Any command you made gets recorded, and you can then retrieve it later on with various commands (my favorite: Ctrl-R , which allows you to search through your history).

So, for example, if we run rake to rebuild any out of date files in Rubinius, we get this: ~/Development/Rubinius ☺ » rake [ … Lots…
PostgreSQL supports custom enum types, which is awesome. However, extending them is kind of a pain, since there is no command to just add a new value to the enum.

One works by modifying the pg_enum , which strikes me as a bit of a bad idea, since those tables are under Postgres’ direct control. The other…
Note: A german translation is available here This post is based on a talk I gave at the 18th Cocoaheads Meetup Vienna (CHW018) on Feb 17th, 2011. It is an annotated tour of my Git config, Git related scripts and commands, and various other tips and tricks I picked up over the years. You can find most of these things in my dotfiles repo, as well with a lot of other stuff, like parts of my Zsh…
