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.
Embedded File System (EFS) is a C++ library that allows you to create virtual file system in a single file. It can be useful when you need to create really big number of small files, as it is still fast even when you have millions of files. An encryption layer could be easily added for security.
MiGLayout is a versatile and flexible Swing and SWT layout manager. It uses string constraints or API type-checked constraints to format the layout. Strings are both short to type and easy to understand. MiGLayout can produce flowing, grid-based, absolute (with links), grouped, and docking layouts. It was created to be to manually coded layouts what Matisse/GroupLayout is to IDE-supported visual layouts.
RRDutil is a a tool to collect statistics (typically every 5 minutes) from multiple servers, store the values in RRD databases (using RRDtool), and plot out pretty graphs to a Web server on demand. The graph types shown include CPU, memory, disk (space and I/O), Apache, MySQL queries and query types, email, Web hits, and more.
LiteWebServer (LWS) is a small, modular Web server and Java web container. It is based on code from Apache's popular Tomcat server, tweaked and extended for easier installation and management. It consists of a set of modules that can be installed separately, so you can install and manage exactly the features you need. The base module provides basic Web server features (HTTP/1.1 support) and support for the Servlet API. Add-on modules provide additional features, such as JSP support. Installing new modules and upgrading or removing existing modules is as easy as can be with the bundled JustGetIt module manager.
Xmake is a console application for building C/C++ projects. It uses XML syntax to describe the necessary files required to build a project and is much easier to explain than make. It is based on a project with one or more "configurations", thus allowing a single file to build across multiple platforms/compilers. Each of the specified source files can belong to one or more of the configurations. The program will automatically do dependency checking for consecutive builds. There are pre- and post-build steps that allow you execute commands to the shell. The pre/post-build steps are also linked to the configuration, so you can be platform specific per configuration.
