This implementation of the Unix write program adds many nice features while remaining close to the standard Unix program in spirit. It has been heavily used on M-Net since 1985 and on Grex since 1991, as well as a few other systems. It is a ground-up reimplementation using no proprietary code. It's available under a Berkeley-style license (no charge, no restriction on commercial use, just don't take my name off of it). The current version is fairly portable. Orville write was written for use on M-Net and Grex, both public access Unix systems in Ann Arbor. As such, many of the features are designed to support a system featuring a delicate mix of novice users and hostile pranksters, plus a lot of people who just want to talk. It's user interface is pretty much identical to the normal write program, but it offers many extensions and improvements.

This little program polls network statistics and does a few things with the data it gets. It has small blinking lights for the rx and tx of IP packets, a digital speedometer of your polled stat's current speed and a bar graph like xload et. al which has a tx speed graph from bottom-up and rx speed graph from the top-down. The speedometer keeps track of the current speed per second and shows it in a color corresponding to which of rx or tx that has the highest speed at the moment. Also, the graph is drawn in a way that the highest speed is drawn on top of the other while the other is in the background.

fswatch: - is a utility to guard changes in a file system. - is composed of three simple programs: fswbuild, fswcmp, fswshow. fswbuild builds a file system information database. fswcmp compares two database files and returns what changes a in file system have been introduced. fswshow shows contents of database file. a file information database is platform independent. - can collect the following information about files (and directories): inode, links, uid, gid, mode, size, flags, ctime, checksum (sha1) ; and can show which files were added, deleted or changed. - is one of many similar utilities. the main difference is the configuration. you can define different settings for every directory in a directory tree. moreover, it is very small and fast.

Eksblowfish is a variant of the Blowfish cipher, modified to make the key setup very expensive. ("Eks" stands for "expensive key schedule".) This doesn't make it significantly cryptographically stronger, but is intended to hinder brute-force attacks. It also makes it unsuitable for any application requiring key agility. It was designed by Niels Provos and David Mazieres for password hashing in OpenBSD. Eksblowfish is a parameterised (family-keyed) cipher. It takes a cost parameter that controls how expensive the key scheduling is. It also takes a family key, known as the "salt". Cost and salt parameters together define a cipher family. Within each family, a key determines an encryption function in the usual way. This distribution also includes an implementation of "bcrypt", the Unix crypt() password hashing algorithm based on Eksblowfish.

PyBlosxom is a lightweight weblog system. It originally started out as a Python clone of Blosxom but has since evolved into a beast of its own. PyBlosxom focuses on three things: simplicity, extensibility, and community. simplicity - PyBlosxom uses the file system for all its data storage. Because of this you can use whatever editor you want to use to create, update, and manipulate entries. extensibility - PyBlosxom has plugin framework allowing you to build plugins in Python to augment and change PyBlosxom's default behavior. community - There are hundreds of PyBlosxom users out there all of whom have different needs. PyBlosxom is used on a variety of operating systems in a variety of environments. PyBlosxom is a pretty straight-forward system that allows you to do the things you need to do without building everything from scratch.

Lzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Lzip decompresses almost as fast as gzip and compresses more than bzip2, which makes it well suited for software distribution and data archiving. Lzip is a clean implementation of the LZMA algorithm. The lzip file format is designed for long-term data archiving. It is clean, provides very safe four factor integrity checking, and is backed by the recovery capabilities of lziprecover.

WeatherSpect provides a reasonably accurate simulation of what the weather looks like outside, in ASCII art. It includes rain, snow, lightning, sleet, and hail. The windspeed and cloudiness are reflected in the velocity and quantity of clouds. There are trees that age, reproduce and die over the course of an hour, and a sun and moon that follow the actual sun and moonrise. There's also a dancing turtle.

Grip is a front-end to external cd audio rippers (such as dagrab or cdda2wav). It also provides an automated frontend for MP3 encoders, letting you take a disc and transform it easily straight into MP3s. The CDDB protocol is supported for retrieving track information from disc database servers. Grip works with DigitalDJ to provide a unified "computerized" version of your music collection.

Sndio is a small audio and MIDI framework part of the OpenBSD project. It provides an lightweight audio & MIDI server and a fully documented user-space API to access either the server or directly the hardware in a uniform way. Sndio is designed to work for desktop applications, but pays special attention to synchronization mechanisms and reliability required by music applications. Reliability through simplicity are part of the project goals.

A real-time signal analysis tool and an offline time-frequency browser. It has a built in tone generation capability and it can play back audio files with a multitude of effects and filters. Designed for environmental analysis missions that range from modulation parameter measurements to searching for transient signals that go bump in the night, baudline combines fast digital signal processing, versatile high-speed displays, and continuous capture tools for hunting down and studying elusive signal characteristics.
