bug is a simple tracking system for console users. It only depends on common Unix commands. Its database format is a text file containing simple tabbed columns which can be even hand-edited. It uses $EDITOR for submitting or editing the issues and for changing states or priorities. It relies on four fixed fields: ID, Priority, State, and Subject. There is also a fifth free-text field for any other information you may want to store about the issue. There is no database locking or notifications, so it's mostly for tracking the user's own issues.
tkccrypt is a small text file editor frontend for Peter Selinger's ccrypt written in basic Tcl/Tk. The program allows opening and storing only encrypted files, and it guarantees that the decrypted content is never written to disk. Its target audience is made up of users who don't feel confident using a console encryption tool, but need encryption for some text data. The dependency only on ccrypt and Tcl/Tk makes this program very easy to run on many Unix systems.
task spooler is a Unix batch system where the tasks spooled run one after the other. The amount of jobs to run at once can be set at any time. Each user in each system has his own job queue. The tasks are run in the correct context (that of enqueue) from any shell/process, and its output/results can be easily watched. It is very useful when you know that your commands depend on a lot of RAM, a lot of disk use, give a lot of output, or for whatever reason it's better not to run them all at the same time, while you want to keep your resources busy for maximum benfit. Its interface allows using it easily in scripts.
Stream Replace replaces binary data in streams (from stdin to stdout). It has two parameters: you pass a string that should literally match, and the replacement string. On stdout, every occurrence will be replaced, byte by byte. It does a job 'sed' usually cannot do: change non-text files.
Terminal Mixer allows sharing the stdin/out/err of a process through a Unix socket, TCP, or raw ethernet (the latter only on Linux). It allows sharing a pseudo-terminal as well, for terminal-aware applications. The users can be allowed only to watch, or even to contribute. You can run your favourite 'vim' or 'bash' and access it remotely, even with multiple users using them.
offrss is a standalone program that can download your favorite feeds and then show them in your favorite Web browser by spawning a simple local Web server. It will not only download the feeds' text, but also the pictures, so you will also be able to read comics strips and enjoy posts with pictures in them while offline. It can also generate PDFs from text. It remembers what you read and what you don't, and all the information stays in normal files, so you can synchronize it easily to any device that may not have an Internet connection. It can also work as a CGI to serve your feeds in your Web site, and it can update the feeds from crontab. It has few dependencies to build and can be cross compiled easily.
filegive easily sends or receives files point-to-point, with authentication and ciphering, and the other side only needs a Web browser. No third party server is involved in the transfer. It can use common NAT traversal protocols like uPnP and NAT-PMP, manually forwarded ports, or a public ssh server.
Development stopped for Terminal Mixer
I stopped developing this program for the more featured Terminal Mixer (http://www.freshmeat.net/projects/terminalmixer). 'tm' can do everything 'stdinmix' could do, and much more.
Noone maintaining this (and OSS)
I tried to contact the author, and he doesn't seem to read the email box provided in the project web page.
I made a module for using OSS instead of Alsa: sound_oss.c (http://vicerveza.homeunix.net/~viric/soft/speextalk/sound_oss.c). Change the Makefile for it to use the OSS module instead of the Alsa.
(I have a via82xxx sound card which records well only in OSS. In fact, OSS over alsa. But it doesn't work in alsa directly. I don't know why)
