ssct is a command-line utility, humble of intent, that takes a single word, spell checks it, takes the result(s) and then translates them. It works to/from english only. From/to languages are limited by ispell in the first instance, and by the IDP (Internet Dictionary Project) files in the second. Currently the latter includes Spanish, Portuguese (minimal), Latin, German, French and Italian. These files are included with this package. This utility was originally created to make it easier to decode badly-scrawled postcards from Spain.
Spiral Synth is a physically modelled polyphonic analogue synthesizer. It is capable of creating the kind of sounds made by hardware analogue synths, the noises used in electronic music. You can also use it to make stranger sounds too. MIDI is supported, and it uses the standard OSS/Free sound output (/dev/dsp).
SOLO (ShagOs LOader) is an x86 bootloader that can directly load and execute protected-mode 32-bit ELF, a.out, and plan9-a.out binaries. It contains a simple boot shell and can run customized scripts to provide boot menus, password protection, etc., at boot time. It comes with commands for scanning for available video modes, unzipping gzip'ed files, and a kernel interface that allows it to call back into 16-bit real mode for BIOS calls, etc. Some debugging facilities are also provided, such as default trap handlers and the ability to set a hardware breakpoint. The initial console I/O can be redirected over a serial port for headless systems.
