Euphoria is a simple, flexible, easy-to-learn programming language. It lets you quickly and easily develop programs for Windows, Linux, FreeBSD, NetbSD, OpenBSD, and Mac OS X. Although Euphoria provides subscript checking, uninitialized variable checking, and numerous other run-time checks, it is extremely fast and has the ability to compile to transparently compile native executables via C code.
GeneWeb is a system for people who want to publish their genealogy data on the Web. It can also be used locally (not connected on the net) as a normal genealogy program. It uses very efficient techniques of relationship and consanguinity computing, speaks several languages, and can run in conjunction with an existing Web server (CGI) or standalone using its own internal server.
HTML::Mason is a full-featured web site development and delivery system. Mason allows web pages and sites to be constructed from shared, reusable building blocks called components. Components contain a mix of Perl and HTML, and can call each other and pass values back and forth like subroutines. Components increase modularity and eliminate repetitive work. HTML::Mason is most powerful when used in conjunction with mod_perl, but can be used in standalone applications as well.
RADpage is a rapid application development system for dynamic, data-driven Web applications. It directly operates inside the browser without requiring a client-dependent development environment. RADpage comes as an Apache module or a CGI, includes a powerful HTML/XML like object-oriented programming language called heitml (pronounced "Hi-TML"), and more than 150 Web application components. Development is done on a fully functional application instead of requiring the edit-save-browse cycle associated with conventional client-side development environments. The RADpage editor stores application pages in readable well-formed XML or upon request in HTML for editing with HTML editors.
SteelBlue is an Open Source Web application server similar to Cold Fusion. It extends HTML with tags to execute SQL commands, perform type checking on user input, loop over sections of code, and manipulate data. In addition, it has a Perl-like scripting language that can be embedded directly into the HTML for complex data manipulation. SteelBlue runs as a CGI script on Linux, UNIX variants (via gcc 2.8), and Win32. It includes native support for most popular relational databases and the embedded scripting language is extensible though a C++ API. Included in the distribution are a book about programming SteelBlue, many examples, and a full bulletin board application.
Web Photo Album automatically generates photo albums on the fly from directories containing your favorite photos. Supports captions (including HTML tags), definable page sizes, forward and reverse preview, and index pages. All preview and index pages can be clicked to jump straight to the page that contains them. Album maintenance is easy -- just add or remove photos and (optionally) captions to your album directory.
SiteManager is an Open Source Web Application Toolkit for PHP Developers that includes a framework for code modules and layout templates, database connectivity, SmartForms, sessions, and some other tools. All parts of the system are integrated through object-oriented libraries which allow for easy expandability and maintenance.
