Tutorials - MacResearch I followed a link to the latest article on MacResearch today, a tutorial on setting up a simple backup system using launchd and rsync, and discovered a terrific repository of tutorials that I'd like to visit later. MacResearch is the "Online Community and Resource for Mac OS X in Science," so these are all geared to the needs of scientists first and foremost. But they have useful general-purpose applications as well. Most of the tutorials cover AppleScript and Cocoa (Objective C).
