nut is nutrition software to record what you eat and analyze your meals for nutrient composition. The database included is the latest USDA Nutrient Database for Standard Reference. This database contains values for vitamins, minerals, fats, calories, protein, carbohydrates, fiber, etc., and includes the essential polyunsaturated fats, Omega-3 and Omega-6. Nutrient levels are expressed as a percentage of the Daily Value, the familiar standard of food labeling in the United States, but also can be fully customized. Foods can be added from recipes or food labels, and nutrient intake can be graphed. The program is completely menu-driven and there are no commands to learn.
Octaviz is a visualization system for Octave. It is a wrapper that makes all VTK classes accessible from within Octave using the same object-oriented syntax as in C++ or Python. It also provides high-level functions for 2D and 3D visualization. Using those functions, most common visualization tasks (3D surface plots, contour plots, meshes, etc.) can be accomplished without any knowledge about VTK.
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.
Pactester is a tool to test proxy auto-configuration (PAC) files. PAC files are used by browsers to identify the correct proxy server for a given URL. Since the PAC file evaluation mechanism is generated inside the browser and cannot be accessed from outside, the only way to tell which proxy your browser will use for a specific URL is manual inspection of the PAC file. Unfortunately, this approach is error prone and quickly becomes impractical for large and complex PAC files. Pactester resolves this issue by simulating browser behavior.
pdnsd is a Proxy DNS server for Linux and FreeBSD that is designed to cope with unreacheable nameservers (e.g. because the dial-in link is not up) in a graceful manner to prevent DNS-dependent applications like Netscape from hanging. It has a permanent disk cache (i.e. the cache contents are saved in a file on exit) and supports parallel query and a wide variety of link uptests. It also has the ability to serve some types of locally defined records.
phalanx computes a digest of many buffers simultaneously, and produces a combined hash of them all. It is an initiative to provide a fast, simple, and portable alternative method to compute a checksum in a parallel fashion. It has options for I/O buffer size, hash width, number of threads, and more. It can be run single-threadedly for performance comparisons. It can check files against previously-saved sums, like "MD5sum" does. It also has a "demo" mode, to ascertain accurate operation. It is intended to be useful on large files and multicore/multiprocessor/multithreaded environments.
pmcyg is a tool for creating customized collections of Cygwin packages together with the Cygwin installer. This enables self-contained distributions to be created without having to mirror the entire set of Cygwin packages. For example, it can create a single CD-ROM or DVD from which a personalized version of Cygwin can be installed on machines not connected to the Web. A basic installer can be created in less than 25MB; a full set of Cygwin packages might fill a DVD-ROM; or a selection of packages can be constructed to suit your chosen installation medium. pmcyg will then download these and all their dependencies automatically. pmcyg can be used either as a command-line script or via a simple graphical interface.
prerex is an interactive (command-line) editor and a LaTeX macro support package that can be used to create very attractive and readable prerequisite charts. A graphical front-end for the editor also provides a prerex-enabled PDF viewer. A prerequisite chart is a network of course boxes linked by prerequisite and co-requisite arrows.
