Terminal
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.
You probably know the feeling. You're writing a piece of code, and just by looking at it, you know it could be better -- but you don't know how. You have that feeling that the right solution is just around the corner, if only you could reach it... but you
Zsh
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). At any given time, I usually have anywhere between 10
Zsh
REPORTTIME is a nifty feature of zsh. If you set it to a non-negative value, then every time, any command you run that takes longer than the value you set it to in seconds, zsh will print usage statistics afterwards as if you had run the command prefixed with time.
PostgreSQL
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. Thanks to this StackOverflow answer, there are two alternate ways to still get what you want. One works by modifying

If you're a command line junkie like me, your commands sometimes tend to get long and complicated. And then you spot a typo somewhere in the middle. Or you forgot a command somewhere. You now have two options: You can use the arrow keys (or, if you know your shell,
One of the important principles in software design is simplicity. You shouldn't over-engineer your programs, and you should not add features that aren't needed. What it doesn't mean is taking the easy way when creating a program. Putting effort into a proper design and structure, choosing proper names (an art
Terminal
Say you want to download a list of files with a command line tool. Since each of those files is quite large, and (as it is the case with me) running only one download process won't fully utilize your internet connection, you could write a script that executes n download
Git
Update 2015-07-29 The git-new-workdir script has been superseded by the git-worktree command added in Git 2.5. The post below is for historical reference. The git.git Repo has a little folder inside it called contrib. It's a place for everything that a Git user might find useful, but (for

One of the things that is pretty much unique to Git is the index (also known as the cache or staging area). The index is the place where you prepare your next commit. In other systems whenever you make a commit, all the changes you made in your working copy
Just like in Rails: require 'erb' template = ERB.new <<-TEMPLATE This is a template from <%= @context %> with yield: <%= yield %> <%= yield :one, :two, :three %> Text after yield TEMPLATE class Context def initialize @context = "context" end def get_binding binding end def handle_yield(args) "Yielding with args: #{args.inspect}" end end ctx = Context.new template.run(ctx.get_
Git
If you're using Git, you're probably aware of submodules. They're useful when you want to integrate and track another Git repository into your own. But there are two other options at your disposal. The first one is to simply merge the other repository. This works fine as long as there
