Flight Navigation Planner lets you make flight plans based on known airports, navaids, fixes, or cities. You can use the sectional charts, wacs, or the vector/terrain planning charts. It calculates headings, winds, time, and fuel. It features Airways-based Auto-Routing, Climb and Descent calculations (a/c type based), Fuel Stop Planning, Auto-Route around MOAS and Restricted Airspace, Hi-Res Weather Radar Overlay, Viewing of current sectional, wac, and IFR charts, the ability to see a route over TFRs, detailed nexrad radar overlays over your routes, Terrain Profiles with cloud ceilings, and the ability to upload flight plans to GPS.
distributed.net is a loosely knit group of computer users from all of the world that is taking up challenges requiring lots of computing power (most notably the RC5, DES, and OGR cracking contests). It is simple to participate in the challenges by downloading and running their client software (which uses idle CPU time to complete its tasks).
Gyach is a GTK+-based Yahoo! Chat client which can use your existing Yahoo! logins for chatting in Yahoo! Chat. It supports colors, emotes/aliases, PMs, set status, remote user status display, ignore lists (local, non-Yahoo! based), a regex list of triggers to cause users to be automatically ignored, command-line recall via arrow keys, and tab completion of usernames.
The dANN project is a library to help facilitate artificial neural networks, artificial intelligence, and artificial genetics within other applications. It is currently written in Java, C++, and C#. However, only the Java version is currently in active development. The other versions can only be obtained from SVN. It provides a powerful interface for programs to include conventional artificial intelligence technology and artificial genetics into their code. It also acts as a testing ground for research and development of new concepts.
Gangplank is a Computer Mediated Communication (CMC) system (or "chat server") which supports real-time communication between users, currently using a text-based user interface. It runs as an Internet server which implements the standard telnet protocol, so no special client program is necessary for users. Server-side processing provides input editing/history and terminal- handling features over the telnet connection for standard ANSI terminals. This code has been in production use on a private server since early 1993. This single-process server is fast, efficient and stable.
pftp allows you to send and receive files and directories recursively, send and receive standard input and ouput, filter your connection, set the net buffer size, set the bandwidth, send UDP datagrams unicasted, broadcasted, and multicasted (which is meant for AUDIO and VIDEO streaming), send data to another user and manage that data, perform a network test based on either UDP or TCP, and use optimized buffers for your Gigabit Ethernet links. pftp can start from command line, as a daemon, or by inetd. All features are supported for IPv4 and IPv6.
