LaunchControl is a fully-featured launchd(8) frontend allowing you to manage and debug system and user services on your Mac. It provides everything you need to load, unload, start, create, edit, remove, or troubleshoot launch services. It supports all documented features of launchd, reports potential problems before a job is even started, and makes sure you always create valid configurations. It supports user LaunchAgents and Global and System LaunchAgents/Daemons. It shows all services and their status at a glance, and misconfigured services are highlighted. You can enable or disable services, and find them with a job filter. Not just a plist editor, it provides a dedicated interface for every configuration key with an adaptive interface that displays only information relevant for the selected job.
Pkviz is a tool for plotting and cycling through and animating a series of network packets captured by tcpdump. What makes it unique is that the packets’ structure is visualized, not any labels and not time itself. Pkviz takes each byte in a packet and plots it out end-to-end, left-to-right, from the first byte to the last. How high the dot gets plotted depends on the value of the byte: bytes with a value of 0 are at the bottom and those which are 255 (0xff) – the maximum value of a byte – get plotted at the top. This might not be interesting for one packet, but that changes when you start looking at thousands of packets. Pkviz can cycle through thousands of packets in the set so you can see what happened on the wire.
Quota Check is a simple application which is designed to run when a user logs into a computer. If they have less than a certain amount of free disk quota, they are told to visit the system administrator and are logged out. When a user tries to log into a network home directory which has a quota enforced, and they don't have enough disk space, they risk corrupting their files. Quota Check makes this situation very clear to users who may be otherwise unaware of the problem.
GPS Tool is a flexible tool for downloading and processing GPS data on Mac OS X. The tool itself is a front-end for various cross-platform tools, namely GPS Babel and scripts which are used to download GPS data. The tool is very easy to use and allows you to define preset processing scripts for batch processing large amounts of GPS data. The plugin system allows you to integrate device discovery and GPS data download into an easy-to-use GUI.
OFXKit is an Objective-C framework for parsing OFX files into a class hierarchy. Since OFXKit is a native Cocoa framework, Mac OS X development technologies can be easily used with OFXKit. Its main features include OFX 1.x and 2.x support, banking, loan, and investment message sets, and creation of OFX request documents for the "Direct-Connect" feature of many banking Web sites.
