The Amazing Awk Assembler (aaa) is a primitive assembler written entirely in awk and sed. It is quite slow, the input syntax is eccentric and rather restricted, and error checking is virtually nonexistent, but it does work. Furthermore it's very easy to adapt to a new machine, provided the machine falls into the generic "8-bit-micro" category.
snmp2xml is a program to convert snmpget output to XML. The output from snmpget, snmpwalk, or snmpbulkwalk is first filtered to correct for SNMP agent flaws and then processed into XML. This XML can be passed through xmllint to tidy it up or it can be processed by an XQuery or XSLT processor. The XML output represents all the SNMP data such that the original SNMP output can be reproduced if desired with an XSLT stylesheet (which is included). The snmp2xml converter has been tested on 7 SNMP agents: Mac OS X, Apple Time Capsule, the Billion ADSL router, the Huawei S9306 switch, the Foundry/Brocade CES and MLX-4 switches, and the Nortel 425 switch.
The Heirloom Toolchest is a collection of standard Unix utilities. It was derived from original Unix material released as open source by Caldera and Sun, and contains multiple versions of each utility corresponding to SVID3/SVR4, SVID4/SVR4.2MP, POSIX.2-1992/SUSV2, POSIX.1-2001/SUSV3, and 4BSD (SVR4 /usr/ucb). It processes lines of arbitrary length and in many cases binary input data, supports characters in UTF-8 and many East Asian encodings, and contains more than 100 individual utilities including bc, cpio, diff, ed, file, find, grep, man, nawk, oawk, pax, ps, sed, sort, spell, and tar. Extensive documentation is included.
Werc is a minimalistic RESTful Web application framework and content management system. It follows the Unix "tool philosophy" and it is designed to be fast, simple, convenient, and easily extensible. It handles both small and big sites and has a flexible system for user and group permissions. All data is stored in plain text files that can be easily manipulated with standard tools, without using any databases or other external dependencies. Existing applications include a blogging engine with RSS/Atom feeds, a wiki system that can easily integrate pre-existing documents (can be enabled for any directory tree), and others.
Plait (pronounced "play") is a command-line jukebox and music player front end. It understands brief, easy to type queries that pick a single song, mix queries that combine works from multiple artists, and stream queries that find Shoutcast radio streams. A variety of filters are available to pick just the music you want to hear. In order to actually play the music it finds, Plait automatically hands off a playlist to one of the supported music players, or creates a playlist that you can manually load.
histbackup makes incremental backups of a directory tree in a set of directories named by dates, or date-time if the date already exists. Its companion script histbackup-prune controls the archive growth. The new backup is prepopulated by hardlinks of each file from the previous backup and then updated with rsync(1). This arranges that the only new content of each new backup is fresh copies of the changed files. In this way each backup directory is a full copy of the source directory but the disk space cost is that of an incremental backup. Because it uses rsync, it is possible to efficiently backup remote directories in this manner.
