A tool that "multiply imputes" missing data in a single cross-section (such as a survey), from a time series (like variables collected for each year in a country), or from a time-series-cross-sectional data set (such as collected by years for each of several countries).

sn a small news system for small sites serving perhaps a few dozen newsgroups, and with a slow connection to the internet; similar to Leafnode. The target user is a home or SOHO with a single modem connection to the Internet, maybe running IP masq or similar, and serving a few workstations.

RC5 is a fast block cipher designed by Ronald Rivest for RSA Data Security (now RSA Security) in 1994. It is a parameterized algorithm with a variable block size, a variable key size, and a variable number of rounds. This particular implementation is 32 bit. As such, it is suggested that a minimum of 12 rounds be performed.

The Link Grammar Parser is a syntactic parser of English, based on link grammar, an original theory of English syntax. Given a sentence, the system assigns to it a syntactic structure, which consists of a set of labeled links connecting pairs of words. The parser also produces a "constituent" representation of a sentence (showing noun phrases, verb phrases, etc.).

pp2html creates a set of HTML files for a foilset based on a simple textfile slide_text. Due to its formatting features and the capability of creating navigation, table of contents and index pages, pp2html is also a suitable tool for writing online documentation. pp2latex creates a LaTeX file from a PerlPoint input file.

Anemone is a Ruby library that makes it quick and painless to write programs that spider a website. It provides a simple DSL for performing actions on every page of a site, skipping certain URLs, and calculating the shortest path to a given page on a site.

TWiki is a flexible, powerful, and easy to use Web-based collaboration platform. Use TWiki to run a project development space, a document management system, a knowledge base, or any other groupware tool, on an intranet or on the internet. Web content can be created collaboratively by using just a browser. Developers can create new web applications based on a Plugin API.

LibDS is a small but powerful and easy to use library containing a few very useful data structures. Currently, the following data structures are supported: - a balanced binary tree (an AVL tree); - a binary HEAP; - a QUEUE; - a HASH table; - a SET and a BAG; - a variable length array that can grows dynamically as new elements are added or deleted (PARRAY). - a STACK; LibDS has been designed to be very easy to use, without sacrificing either flexibility or speed. The API is small, and clean.

This is QUISK, a Software Defined Radio (SDR). - Quisk can control the HiQSDR. - As a receiver it can use the SDR-IQ by RfSpace as a sample source. - As a receiver it can use your soundcard as a sample source. - Quisk can control SoftRock hardware for both receive and transmit. - As a transmitter it can accept microphone input and send that to your transmitter for SSB operation. For CW, QUISK can mute the audio and substitute a side tone.

CVSps is a program for generating 'patchset' information from a CVS repository. A patchset in this case is defined as a set of changes made to a collection of files, and all committed at the same time (using a single 'cvs commit' command). This information is valuable to seeing the big picture of the evolution of a cvs project. While cvs tracks revision information, it is often difficult to see what changes were committed 'atomically' to the repository.
