Story: Writing Scripts with Go

Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.

Port forwarding in Mavericks

Port Forwarding in Mavericks


Since Mavericks stopped using the deprecated ipfw (as of Mountain Lion), we'll be using pf to allow port forwarding.

The slowness of my zsh prompt when in a git-svn managed directory was killing me. I improved it by removing the git status stuff that slows it down...
