“What's not clear is how people who don't code contribute their skills and expertise to making OSS software. Because it's not clear, they don't, and the software looks and feels like it was designed by engineers, for engineers—because it was.”

“Open source anti-theft solution for Mac, PCs & Phones.”

I use hiddenapp.com, but this looks good. Another option is http://www.orbicule.com/undercover/mac/.

Joe Clark on why those complaining about the closedness of the iPad are complaining about a non-problem. "Open source has nothing to teach literature or indeed any artistic creation, since talent doesn’t scale as you give more and more developers check-in access to the version-control system set up for your novel."

A great selection of VST and AU audio effects plugins for free download.

This may be worth looking into. I waffle on whether this sort of thing is ultimately a good decision — you're relying on someone else's framework, it takes a while to learn and master, and once you decide to go with it you're essentially stuck with it. But isn't that the case with any pseudo-framework developed for a website design? I should test this on a little project.

"Adaptable, minimalist interfaces." Oh. My. God.

"A Mac OS X Leopard developer tool for debugging HTTP services by graphically creating & inspecting complex HTTP messages."

On the characteristic lack of usability in open source projects, and why. "The distributed, collaborative nature of open source software works for developer-level software, but works against user-level software. Imagine a motion picture produced like a large open source project. Different scenes written and directed by different people, spread across the world. Editing decisions forged by group consensus on mailing lists. The result would be unfocused, incoherent, and unenjoyable."

Spaced repetition! "Designed to help you remember facts (such as words and phrases in a foreign language) as easily, quickly and efficiently as possible. To do this, it tracks how well you remember each fact, and uses that info to schedule review times.

"The MacPorts Project is an open-source community initiative to design an easy-to-use system for compiling, installing, and upgrading either command-line, X11 or Aqua based open-source software on the Mac OS X operating system."

"WebKit is an open source web browser engine. WebKit is also the name of the Mac OS X system framework version of the engine that's used by Safari, Dashboard, Mail, and many other OS X applications."

"What if there was a library which held every book? Not every book on sale, or every important book, or even every book in English, but simply every book." Aaron Swartz is at it again!
