BLADE is a Web-based environment similar in nature to Zope, Mason, and Midgard. What distinguishes BLADE is its underlying technology, CORBA, which permits BLADE to function with and support any programming language. Further, BLADE supports object embedding from any language into any Web page, and as such is the first enviournment to allow the embedding and communication of Perl, Python, and C objects within the same page.
Blade-- is a C++ wrapper/interface to the BLADE web-based environment. Blade-- will allow you to use all features of BLADE in a structured object-oriented fashion. Also, the BladeGen-- Code Generator constructs Blade-- project frames to get your BLADE project off the ground quickly.
BlueJ is an interactive Java development environment. It provides a unique user interface that presents a graphical display of the application classes and their relationships, and it lets users interactively create objects of any class. Once objects have been created, users can interact with them directly. This interaction mechanism allows for much greater testing and experimentation than in conventional environments. BlueJ is suited for teaching and learning OO and Java.
The Bluetail Ticket Tracker (BTT) is a system for creating, storing, and keeping track of tickets. A ticket describes an issue of some sort. It can, for example, be a Trouble Report or a ToDo note. BTT also makes it possible to store customer information, which can be coupled to a ticket. BTT comes with a wiki-style knowledge base and an automatic mail store.
Boa Constructor is a cross-platform RAD GUI-building IDE.
