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.
SOGo is a very fast and scalable modern collaboration suite (or groupware). It offers calendaring, address book management, and a full-featured Webmail client along with resource sharing and permission handling. It also makes use of documented standards (IMAP, CalDAV, CardDAV, etc.) and thereby provides native connectivity (without plugins) to many clients such as Microsoft Outlook, Apple iCal, the iPhone, Mozilla Lightning, and a plethora of mobile devices via SyncML. It can reuse any existing email and database infrastructure, avoiding long hours of site restructuring.
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.
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.
Mr.Java is a Java IDE that is one step above a command line interface, but not quite as confusing as an IDE. It will compile for you, add libraries to your class path, and run the whole thing, with three simple buttons. Drag a library or Java source file over the window, and it will be put in the right folder. When running programs, the stout is written to a file cleverly named “stdout”, and the std err is cleverly written to file named - you guessed - stderr.
