OpenADK is a construction kit for embedded Linux. It creates Linux systems that are optimized for size and short bootup times. The toolchain supports many architectures (arm, m68k, mips, microblaze, ppc, sparc, superh, x86, and x86_64). It can build customized images for Qemu. Raspberry PI, Lemote Yeelong, and Sharp Zaurus devices are supported as a proof of concept. Approximately 685 source packages are available.
Backshift is a deduplicating (variable-sized, content-based blocks), compressing (xz or bz2) backup program. Full saves and incrementals are pretty indistinct other than the amount of data transmitted, somewhat like with "rsync --link-dest" but without the huge number of hardlinks. It also de-duplicates large file content at a granularity of about 2 megabytes on average; there tends to be a unique copy of each file with size less than around 2 megabytes on average.
AdlMIDI is a command line program that plays MIDI files using software OPL3 emulation (FM synthesis). It has a console UI. It features a built-in selection of 50 patch sets, most of which are General MIDI compatible, but some of which are customized for playing original background music soundtracks of select PC games.
Bviplus is a console ncurses based binary file editor (hex editor) with Vim-like keys and features. It can quickly open/edit/save very large files (> 2GiB). It can perform regexp-like pattern searches in hex or ASCII windows. It features search highlighting, multiple undo/redo, a tabbed multiple file interface, visual selection, cut and paste (which works between files as well), blob coloring, and more. It can run external programs on selected data, supporting any program that reads stdin and writes stdout. It has few dependencies for easy portability.
The SMS Server Tools 3 is a SMS gateway that can send and receive short messages through GSM modems and mobile phones. Messages are sent by simply storing text files into a special spool directory. It also stores received messages into another directory as text files. Binary messages including Unicode text and ring tones are also supported, and it is possible to send WAP Push and system messages. The program can run scripts after events like the reception of a message, successful sending, and when the program detects a problem.
Meep is a free finite-difference time-domain (FDTD) simulation software package to model electromagnetic systems. It supports distributed-memory parallel simulations, nonlinear, anisotropic, and dispersive media, PML absorbing boundaries, and 1D/2D/3D and cylindrical problems. It is completely scriptable from either C++ or a Scheme (GNU Guile) interface.
Evergreen is a cross-platform development environment that tries to be lightweight and language-agnostic yet functional. It started as a project to reimplement Rob Pike's Acme editor for Plan 9 in Java, but has since evolved in directions that help it deal with large codebases and multiple projects/branches at once. Remaining similarities include the tiled windows and the Unix-like reliance on external programs rather than reinventing every wheel. The major philosophical differences include strong support for keyboard-based editing, language-specific functionality, and native platform UI conventions. There are also two new guiding principles: accepting regular expressions and output diffs.
The parallel project allows for simple parallel and distributed processing from shell scripts. In particular, the programs accept lines of shell code on the standard input and run these lines in parallel. The parallelism can be either on the local machine or on a cluster, if a small amount of time is taken to set up SSH. Additionally, the distributed version includes a degree of fault tolerance.
