NSLogger is a high perfomance logging utility which displays traces emitted by client applications running on Mac OS X or iOS (iPhone OS). It replaces your usual NSLog()-based traces and provides powerful additions like display filtering, image and binary logging, traces buffering, timing information, etc.

NSLogger feature summary:

* View logs using the Mac OS X desktop viewer, accept connections from local network clients (using Bonjour) or remote clients connecting directly over the internet
* Online (application running and connected to NSLogger) and offline (saved logs) log viewing
* Buffer all traces in memory or in a file, send them over to viewer when a connection is acquired
* Secure logging (connections use SSL by default)
* Advanced log filtering options
* Save viewer logs to share them and/or review them later
* Export logs to text files
* Open raw buffered traces files that you brought back from client applications not directly connected to the log viewer

Finch is a simple OpenAL-based sound effect player for iPhone. The reasons for writing Finch instead of sticking with Apple’s AVAudioPlayer are described in my question on Stack Overflow. The goals are simple: (1) Play sound effects without much fuss, and (2) do not lag in the play method as AVAudioPlayer does. Finch is not meant to play background music. If you want to play background music, you can go with AVAudioPlayer. Finch will play the sound effects over the background music just fine.
