Arq is an application for backing your Mac up to Amazon S3 (via Matt Henderson). I’m happy with CrashPlan, but Arq promises advantages such as better support for metadata and direct access to your backup data in a documented, Git-like format. S3 has an API and many clients, and Amazon is likely a very stable host, but it’s also considerably more expensive if you have hundreds of gigabytes of files.

PFiddlesoft Frameworks

Bill Cheeseman, developer of the UI Browser and UI Actions AppleScript utilities, has released some of his applications’ core technology as frameworks. The PFAssistive and PFEventTaps frameworks are Objective-C wrappers for the Accessibility and Quartz Event Tap APIs. There’s extensive PDF and HeaderDoc documentation, and for an extra fee you can get the source code. Garbage collection is not supported.

MacPaint and QuickDraw Source Code

The Computer History Museum:

For those who want to see how it worked “under the hood,” we are pleased, with the permission of Apple Inc., to make available the original program source code of MacPaint and the underlying QuickDraw graphics library.

Xcode won’t open the .a files for display. I recommend viewing using BBEdit, which has syntax highlighting for both Pascal and 68K assembler files.
