BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
PHP Weather makes it easy to show the current weather on your Web page. PHP Weather retrieves the latest METAR (weather) report and converts this format into both imperial and metric units, caches the data in a MySQL, PostgreSQL, or DBA database for fast retrieval, and makes it easily available in PHP scripts. You can display the data in several languages by using the included translations.
SIDB (Scientific Image Database) is a Web-driven database for (scientific) images. Entry of image meta-data is facilitated through the use of user-definable templates. Users have complete control over who else may see the submitted image and data. SIDB offers various views on the actual image data. Thumbnail plus meta-data can be printed, and multiple thumbnails can be combined in galleries. A freeware version of the Huygens software (http://www.svi.nl) can be used to generate projections from 3-D images (most confocal microscope image formats are supported), as well as MPEG movies, showing the individual layers from the 3-D images.
PHPLOT is a PHP graphics class for creating charts and plots. It works with PHP5 (but older versions can use PHP4). PHPlot uses the PHP GD extension to produce PNG, GIF, or JPEG images. TrueType fonts (TTF) are optional, or built-in GD fonts can be used. The available plot types are: area, bars, line/points, lines, pie, points, squared, stacked-bars, and thin bar-line. Labels, tick marks, plot legend, X/Y axes, and more are all configurable. Images can be imported as a background, multiple graphs can be drawn on one image, and images can be saved to disk or returned to a browser.
PasTmon (Passive Application Response Time Monitor) passively monitors your application servers, measuring and reporting user response times, throughput and congestion. It currently works with HTTP, telnet, rlogin, rsh, FTP (control channel), SMTP, POP3, and IRC. Measurements are recorded in a PostgreSQL database and are presented graphically via a PHP Web front-end using R statistical analysis scripts to create the plots.
Cyberbrau is a Web-based program to help the homebrewer. It allows for very simple and intuitive beer, cider, and mead recipe creation, and it automatically calculates all the pertinent information based on the selected ingredients and schedule. In addition to the recipes, it allows multiple brewers to privately track their own batches, emailing them on racking, bottling, and lagering dates. Finally, it has a 'taster's review' section which allows those who try your brew to rate and comment on the batch. This information goes into the overall recipe ranking.
