Jikes RVM (Research Virtual Machine) provides a flexible open testbed to prototype virtual machine technologies and experiment with a large variety of design alternatives. Jikes RVM runs on many platforms and advances the state-of-the-art of virtual machine technologies for dynamic compilation, adaptive optimization, garbage collection, thread scheduling, and synchronization. It is self-hosted, i.e. its Java code runs on itself without requiring a second virtual machine. Most other virtual machines for the Java platform are written in native code (typically C or C++). A Java implementation provides ease of portability and a seamless integration of virtual machine and application resources such as objects, threads, and operating-system interfaces.
DaVite is a Web invitation system, much like evite! or Yahoo! invites. You can use it to create a Web invitation that is mailed to all of your guests, who can then read the details, and respond online. Invitations are themeable, and can include user images, so they are completely customizable.
E-MailRelay is a simple SMTP store-and-forward mail transport agent (MTA). It runs as an SMTP server, storing incoming e-mail in a local spool directory, and then forwarding the stored messages to a downstream SMTP server on request. It can also run as a proxy server, forwarding (and optionally pre-processing) incoming e-mail as soon as it is received. It does not do any message routing other than to a local postmaster. Because of its simplicity E-MailRelay is extremely easy to configure, typically requiring only the address of the downstream SMTP server to be put on the commandline.
Folding@home simulates protein folding. We do not entirely understand how proteins actually operate, but one important step is to study how proteins self-assemble or "fold." This is an extremely computationally intensive task since proteins take in the order of microseconds to milliseconds to fold, yet we can only routinely simulate over nanosecond to microsecond time scales. This system provides a new way to simulate protein folding that can break the millisecond barrier by dividing the work between multiple processors. Thus, with 1000 processors, we can break the millisecond barrier and help unlock the mystery of how proteins fold.
OGRE (Object-Oriented Graphics Rendering Engine) is a class library written in C++ designed to make it easier and more intuitive for developers to produce games and demos utilising 3D hardware. It exposes a number of useful objects allowing you to create and manipulate a 3D environment and render it to your specifications, while removing the unnecessary complexities of the underlying system libraries like Direct3D and OpenGL.
Calcoo is a scientific calculator designed to provide maximum usability. Its features bitmapped button labels and display digits to improve readability, no double-function buttons, undo/redo buttons, copy/paste interaction with the clipboard, both RPN and algebraic modes, two memory registers with displays, displays for Y, Z, and T registers, and tick marks to separate thousands. Calcoo is written in C using the GTK+ widget library (v.2.2+).
Emdros is a corpus query system for storing and searching linguistically annotated text. It is very generic, supporting almost any kind of annotation from almost any linguistic theory. All linguistic levels of analysis are supported, including phonology, morphology, the lexical level, syntax, and discourse. The core libraries act as a middleware layer between a client and an underlying SQL database. MySQL, PostgreSQL, and SQLite (2 and 3) are supported.
The VideoLAN Server (VLS) can stream MPEG-1, MPEG-2, and MPEG-4 files, DVDs, digital satellite channels, digital terrestial television channels, and live videos on a network in unicast or multicast. A VideoLAN Client (VLC) or a set top box can receive the stream, decode, and display it.
omega is a complex rogue-style game of dungeon exploration. Unlike other such games, there are a number of ways to "win", depending on various actions taken during play. The ways you can get your name on the hiscore board include becoming the highest ranked head of a guild, sect, college, etc., as well as gaining the most points figured from possessions and experience. The game (via the oracle) may impose some structure on your exploration, but you need not follow all of the oracle's advice. There *is* a "total winner" status, by the way.
