When a user notification fires while your Mac app is already in the foreground, this code plays the sound, but suppresses the rest of the notification. Put it in your user notification center delegate.

Property list serialization protocol/category. This allows you to easily make an NSObject subclass generate a plist version of itself, or initialize itself from a plist. Simply conform to the TsPropertyListRepresentation protocol and call the +includeKeyInPropertyListRepresentation:... methods at an appropriate time, such as an +initialize metho…

Subclass of NSPortNameServer that uses distributed notifications (in a sandbox-friendly way) to implement a fast name server for socket ports. Decent demonstration of NSDistributedNotificationCenter, stupid run loop tricks, and SecTransform.

This gist includes a quick syntax for constructing NSIndexSets—[@0:9] and [@0:9 step:2]—and fast enumeration support for NSIndexSet (yielding NSNumbers). The result is that you can enumerate over ranges using for/in. The gist is CodeRunner ready.
