Libchop is a set of utilities and library for data backup and distributed storage. Its main application is chop-backup, an encrypted backup program that supports data integrity checks, versioning at little cost, distribution among several sites, selective sharing of stored data, adaptive compression, and more. The library itself, which chop-backup builds upon, implements storage techniques such as content-based addressing, content hash keys, Merkle trees, similarity detection, and lossless compression. It makes it easy to combine them in different ways. The ‘chop-archiver’ and ‘chop-block-server’ tools, illustrated in the manual, provide direct access to these facilities from the command line. It is written in C and has Guile (Scheme) bindings.
tzls and tzx are commandline utilities for quickly unpacking or listing the contents of various types of common Unix archive files, which may be compressed in any of several ways. The supported compression types are bzip2, gzip, and compress. The supported archive types are tar, cpio, zip, rar, and arj. The tools are implemented as shell scripts, so no compilation is required.
OMCSNetCPP is a C++ API and inference toolkit for accessing OMCSNet, a semantic network mined out of the Open Mind Common Sense knowledge base. The goal of this project is to provide a class library that allows programmers to easily add common sense reasoning capabilities to C++ applications.
The Internet Gopher Client is based on the UMN Gopher/Gopherd 2.3.1 code. Gopher is an Internet technology that predates the Web. It presents information as a virtual network-wide filesystem. Modern browsers such as Konqueror can display gopherspace as if it contained files on your local machine (trees, drag and drop, etc.), but the difference is that each file or folder in that tree may be on a different machine.
Flight Navigation Planner lets you make flight plans based on known airports, navaids, fixes, or cities. You can use the sectional charts, wacs, or the vector/terrain planning charts. It calculates headings, winds, time, and fuel. It features Airways-based Auto-Routing, Climb and Descent calculations (a/c type based), Fuel Stop Planning, Auto-Route around MOAS and Restricted Airspace, Hi-Res Weather Radar Overlay, Viewing of current sectional, wac, and IFR charts, the ability to see a route over TFRs, detailed nexrad radar overlays over your routes, Terrain Profiles with cloud ceilings, and the ability to upload flight plans to GPS.
fff and ffl are tools for searching for files and directories from the Unix shell with more integrated "shell-like" behaviour and simpler syntax than find(1), though find(1) is still used to perform the actual searches. In particular, there is no need to quote wildcards, and searches are case-insensitive. Matching results are shown one per line. fff displays full paths, and ffl relative paths. Detailed find(1) options can be appended to the fff/ffl command line if desired. These utilities are based entirely on shell aliases and functions, so no compliation is required.
Wocvim is a WoC client for Vim. WoC is a protocol which enables the use of hyperlinks in plain ASCII texts. The links can point to local or remote locations. The protocol is specifically designed to support source code, but it can be used in any text. For source code, it's also possible to use ad-hoc tag generators like cscope and ctags.
