Over the past few days, I have been hacking a lot, mostly for work, but also a little for non-work. I have discovered or re-discovered many power-user bits of zsh, my interactive shell of choice. In between long stretches of late-night firefighting (routers melting, electrical systems failing, infrastructure subsystems behaving oddly), I am moving some of my little webapps from their miserable perl or python existences into a world of ruby. Part of this is sped along by nice interfaces such as the flickr API and instiki (wow, what a great name for a wiki!).
Another really nice thing is that, barring configuration parameters, the code works seamlessly on either the powerbook (for development) or the linux or g4 servers. Rich Kilmer blogs about some hacks to get ruby working more smoothly under tiger.
