magicErmine is a tool for creating portable applications for Linux. It allows the same Linux executable to be run on a wide range of different distributions. Like statifier, It makes one executable file with no run-time dependencies from a dynamically linked executable and all of its libraries. Unlike statifier, it is able to add arbitrary files to the packed executable, such as configuration files or pixmaps.
Chicken is a Scheme compiler that translates most of R5RS Scheme into relatively portable C. It supports fully general tail-call recursion, first-class continuations, and has a very flexible and efficient interface to C and C++. Chicken implements several extensions to the Scheme language: lightweight threads, pattern matching macros, dynamic loading of compiled code, and various object-oriented paradigms, such as TinyCLOS, and others. The library system includes hundreds of convenient modules for practical use.
MUSCLE (Multi User Server Client Linking Environment) is an N-way messaging server and networking API. It includes client-side networking APIs for various languages, including C, C++, C#, Delphi, Java, and Python. MUSCLE lets programs communicate over a network via streams of serialized Message objects. The included server program ("muscled") lets its clients message each other and store information in its server-side hierarchical database. The database supports flexible queries via hierarchical wildcarding, and "live" updates via a subscription mechanism.
AVFS (A Virtual File System) is an easy-to-install system that enables all programs to access archived, compressed, remote, or other kind of virtual files without the need to recompile programs or the kernel. The following modules are currently implemented: tar, zip, rar, gzip, bzip2, ftp, http, dav, rsh/ssh, floppy, and many more.
The xterm program is the standard terminal emulator for the X Window System. It provides DEC VT102/VT220 and Tektronix 4014 compatible terminals for programs that can't use the window system directly. If the underlying operating system supports terminal resizing capabilities (for example, the SIGWINCH signal in systems derived from 4.3bsd), xterm will use the facilities to notify programs running in the window whenever it is resized.
ASPseek is an Internet search engine, written in C++ using the STL library. It consists of an indexing robot, a search daemon, and a search frontend (CGI or Apache module). It can index as many as a few million URLs and search for words and phrases, use wildcards, and do a Boolean search. Search results can be limited to time period given, site, or Web space (set of sites) and sorted by relevance (PageRanks are used) or date. It is optimized for multiple sites (threaded index, async DNS lookups, grouping results by site, and Web spaces), but can be used for searching one site as well. It can work with multiple languages/encodings at once (including multi-byte encodings such as Chinese) due to optional Unicode storage mode. Other features include stopwords and ispell support, a charset and language guesser, HTML templates for search results, excerpts, and query words highlighting.
GCompris is an educational software suite with numerous activities for children aged 2 to 10. Some of the activities are game-orientated, but nonetheless still educational. These include computer discovery (keyboard, mouse, different mouse gestures), algebra (table memory, enumeration, double entry table, mirror image), science (the canal lock, the water cycle, the submarine, electric simulation), geography (place the country on the map), games (chess, memory, connect 4, oware, sudoku), reading practice, and others (learn to tell time, puzzles of famous paintings, vector drawing, cartoon making, etc.). It currently offers in excess of 100 activities, and more are being developed.
Clonezilla is a partition or disk cloning tool similar to Symantec Ghost. It saves and restores only blocks in use on the hard drive if the file system is supported. For unsupported file systems, dd is used instead. It has been used to clone a 5 GB system to 40 clients in about 10 minutes.
