PumpKIN is a fully functional TFTP server and TFTP client that implements the TFTP protocol according to RFC1350. It also implements the block size option, which allows the transfer of files larger than 32MB, as well as transfer size and transfer timeout options described in RFC2348 and RFC2349.
ActoTracker is an application for keeping track of activities on your desktop so that you don't have to. Think of it as an app for bookmarking desktop documents and applications. It can also bookmark things that are not usually tied to a URL such as Outlook email message or Filemaker records. It can be extended to handle additional applications by writing custom AppleScript plugins. ActoTracker is somewhat inspired by the GNOME Activity Journal (Zeitgeist framework), and it tries to solve a similar kind of problem for the end user, although in a different way.
Playtomic is a set of client and server APIs for game leaderboards, user generated content, and dynamic updates. It began as a hosted service providing tools and analytics for game developers, but is now available for developers to operate on their own. It includes the API server which is written in NodeJS and backed with MongoDB, along with game client APIs for HTML5, Flash, iOS, Android, Windows, and Unity3d games.
Tactor is a tool that tries to guess the best action for the current text selection. For example, text containing http://xyz.com is recognized as an URL link, and ~/Documents/MyPresentation.key as a presentation file. Both matchers and actions are fully customizable. It is loosely based on Plan9’s Plumber where any text can potentially be an action, although the actual technical implementation is very different. It provides functionality somewhat similar to that of Apple Data Detectors in a way that is fully extensible and transparent.
