The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort focusing on applying empirical techniques in order to provide portable performance. It provides C and Fortran77 interfaces to a portably efficient BLAS implementation, as well as a few routines from LAPACK.
Argyll is an ICC compatible color management system. It supports accurate ICC profile creation for scanners, CMYK printers, and film recorders, and calibration and profiling of displays. Spectral sample data is supported, allowing a selection of illuminants observer types, and paper fluorescent whitener additive compensation. Profiles can also incorporate source specific gamut mappings for perceptual and saturation intents. Gamut mapping and profile linking uses the CIECAM02 appearance model, a unique gamut mapping algorithm, and a wide selection of rendering intents. It also includes code for a fast 8-bit raster color conversion engine as well as support for fast, fully accurate 16-bit conversion. Device color gamuts can also be viewed and compared using a VRML viewer.
Silva is a CMS for organizations that manage multiple or complex Web sites. Content is stored in clean XML, independent of layout and presentation. Features include versioning, a workflow system, an integral visual editor, content reuse, sophisticated access control, multi-site management, extensive import/export facilities, fine-grained templating, and hi-res image storage and manipulation. Silva is built on top of the Zope Web application platform.
FreeMarker is a template engine that was originally designed so that servlet-based applications could keep graphical design separate from application logic. The templates provide an easy and highly flexible way to generate any kind of text output (HTML, PostScript, TeX, source code, etc.) from a variety of data sources such as Java objects, Jython objects, XML object models, and more.
The Boehm-Demers-Weiser conservative garbage collector can be used as a garbage collecting replacement for C malloc or C++ new. It is also used by a number of programming language implementations that use C as intermediate code. Alternatively, it may be used as a leak detector for C or C++ programs. A slightly older version of the garbage collector is also included as part of the GNU compiler (gcc) distribution.
PHP HTTP protocol client is a PHP class for making HTTP requests. It can establish connections via SOCKS or proxy servers and establish secure connections (HTTPS) with optional SSL client certificates. It supports HTTP Basic, HTTP Digest, and NTLM (Windows or Samba) authentication mechanisms. It submits POST requests with user-defined form values, file uploading, or with user-defined request bodies. It handles cookies and automatic redirection handling. There is an addon class that logs in to Yahoo! and executes actions on behalf of the user, like exporting the address book or sending invitations to Yahoo! groups.
SQLScreens is a simple relational database screen form generator written in TCL/TK. It will let you create query screens very quickly by specifying what data (tables and columns) you want to see and what operations should be allowed (query/update, etc.). It will take care of creating the user interface and the behind-the-scenes SQL. SQLScreens can be used with different backend database systems, and includes direct support for MySQL, SQLite, and INFORMIX, and ODBC for others.
Activity Manager is a project management tool that is simple to use, lightweight, and very efficient and customizable. It features collaborators repository administration, tasks repository administration, contributions management (activity management), and an extensible report facility (with built in templates). It allows you to build and maintain a hierarchical task tree. It is based on a database with a very simple model that allows quickly building custom reports through the report facility or through simple SQL requests.
