Tcl provides a portable scripting environment for Unix, Windows, and Macintosh that supports string processing and pattern matching, native file system access, shell-like control over other programs, TCP/IP networking, timers, and event-driven I/O. Tcl has traditional programming constructs like variables, loops, procedures, namespaces, error handling, script packages, and dynamic loading of DLLs. Tk provides portable GUIs on UNIX, Windows, and Macintosh. A powerful widget set and the concise scripting interface to Tk make it a breeze to develop sophisticated user interfaces.
Botan is a crypto library written in C++. It provides a variety of cryptographic algorithms, including common ones such as AES, MD5, SHA, HMAC, RSA, Diffie-Hellman, DSA, and ECDSA, as well as many others that are more obscure or specialized. It also offers SSL/TLS (client and server), X.509v3 certificates and CRLs, and PKCS #10 certificate requests. A message processing system that uses a filter/pipeline metaphor allows for many common cryptographic tasks to be completed with just a few lines of code. Assembly and SIMD optimizations for common CPUs offers speedups for critical algorithms like AES and SHA-1.
cosign is a Web single sign on system that allows users to authenticate once per session and access any protected Web resources at the institution. If used, passwords are sent only to a single, central URL. Sessions have both idle and hard timeouts, and users can logout of all protected services by visiting a single URL. The use of public key cryptography ensures that a compromise of a protected Web server has no impact on the security of other participating servers.
GeoToad is a geocaching query tool to help speed up the boring part of geocaching: choosing the cache and collecting the data. It allows you to generate any kind of complex query you want, and the program will go and poll the Geocaching query, grab the data, and output it to any format you want. The Geocache info can be synced straight to your GPS, iPod, PDA, or cell phone in over 20 different formats.
ZEngine is a cross-platform 2D API which uses a combination of OpenGL and SDL to provide speed and functionality as well as portability. The library can be used on any platform SDL supports, but for full functionality requires OpenGL and several SDL extension libraries. A class-based design allows the easy management of resources and makes learning the API easy, allowing more time to be spent on the development of the actual game than learning of various APIs. Current development platforms are Windows and Linux, but ZEngine is reported to work on similar operating systems (like OSX), and help is available for anyone porting to any platform.
jAscom is a wrapper around the JACOB (JAva-COM Bridge) libraries for easy access to the ASCOM Platform 3.0 using Java. It provides all functionality (methods and properties) of the ASCOM Telescope API version 2. It also includes the Focuser and Dome API. This means easy and fast coding of Java applications for all sorts of telescope controlling problems, using a widely accepted standard.
