Java Development Environment for Emacs (JDEE) is an Emacs-based integrated development environment (IDE) for developing Java applications and applets.
Features include multiple code browsers, a JPDA-based debugger, method and field completion, template-based and procedure-based code generation, Java source code interpreter, context-sensitive help, and more.
Enhancements:
- On XEmacs, Use efc-xemacs-query-options, i.e., a GUI dialog box instead of a text dialog box, only if use-dialog-box is nonnil.
- Fixes bug in ProjectClasses to avoid duplicate entries of imports.
- Updated JDEEs Ant interface to force use of pipes to interact with external Ant process.
- Fixed regression that caused jde-help-class-member to issue a Lisp error.
- Fixed regression in jde-wiz-update-class-list command.
- Fixed regression that caused JDEbug to issue a Lisp error when launching an application.
- Thanks to Martin Schwamberger.
- Revise the following templates to conform to CheckStyle requirements:
- jde-gen-deep-clone-template
- jde-gen-to-string-method-template
- jde-gen-bean-template
- Thanks to Martin Schwamberger.
- Added the following code generation templates:
- jde-gen-exception
- Generates an exception class in the current buffer.
- jde-gen-exception-buffer
- Generates a buffer containing an exception class.
- jde-gen-hashcode-method
- Generates a hashcode method at point.
- jde-gen-equals-method
- Generates an equals method at point.
- jde-gen-tostring-method
- Generates a toString method that uses Apaches
- ToStringBuilder class.
- Thanks to Ole Arndt.
- Enhanced jde-run-option-classpath to allow you to specify that the JDEE should omit the classpath argument when running the class or application in the current buffer, regardless of the setting of jde-global-classpath.
- Fixed regression that caused the JDEE to switch projects during debugging when stepping into code that does not belong to the project being debugged.
- Updated regular expressions used by the JDEEs interface to jdb to accommodate non-English punctuation styles for numeric expressions in debugger messages, e.g.,
- 1.200 for a line number where the English would write 1,200.
- Thanks to Morten B. Isaksen.
- In previous releases, building javadoc caused all future uses of compilation mode to try to
- display the javadoc. This release fixes the problem.
- Thanks to David Evers.
- Updated the submit-problem-report command to include an XEmacs users init.el file.

Equinox Desktop Environment (shortly EDE) is small desktop environment, builted to be simple and fast.
Comparing to other desktop environments, EDE is much faster and smaller in memory space (EDEs window manager use less memory than xterm).
The word "equinox" comes from the Latin for "equal night". The equinoxes in March and September are the two occasions each year when the day and the night are of equal duration.
For measuring the length of a day, sunrise is the moment when the sun is half-above the horizon and sunset is the moment when the sun is half-under the horizon. Using this definition, the length of the day (and the night) is precisely 12 hours at an equinox.
Main features:
- desktop with icons and wallpaper;
- Xft font anti-aliasing;
- taskbar with configurable menu, cpu status, easy keyboard switching;
- theming;
- localization;
Graphical front-end for:
- xscreensaver configuration;
- software installation (.rpm, .deb, .tgz);
- time and time-zone configuration;
- fast file and directory serch utility;

Frugal Windowing Environment, or FWE, is my basic windowing system for framebuffers. It currently works under Linux only and is in an alpha stage of development. The project is the logical next step from my previous system, FrameBufferUI (fbui), which is a small, in-kernel graphical user interface for Linux.
Main features:
- Frugality
- Small size (the current alpha version is 20 kB).
- Minimal resource requirements.
- Software simplicity
- Client-server architecture, with clients potentially located on remote computers (disabled at present)
- Graphics on each console with one server each.
- Basic drawing commands needed for frugal applications.
- Software bloat keeps us all on the treadmill of always buying new hardware, which ultimately new software makes painfully slow, thus we are always falling behind. But the software makes the system slow because it is poorly designed and poorly implemented and rushed work, with the frequent consequence that it is bloated. Thus the purchasing-treadmill is economically and materially wasteful. It profits the few while making the many suffer unnecessarily.
- Bloat is also bad for the Environment (which we live in and rely upon) since the manufacture of computer equipment involves the use of numerous very nasty chemicals which inevitably end up in the soil, water and air. Similarly the disposal of electronics results in chemicals leaching out of circuit boards, LCDs (which contain mercury) et cetera, which then enter the biosphere. We cannot afford to pretend this problem doesnt exist and we cannot afford to leave it to self-serving politicians to solve. It is better to solve the problem at the source: buy less hardware. (Article)
- Liberation from bloat is liberation from rushed work, poorly managed projects, and bad engineering. It is liberation from those project managers and programmers who, rather than produce better, leaner, less buggy software, pass on the consequences of their bad choice to users who must pay to upgrade their hardware to accommodate the bloat. And as that software gets bigger and bulk is piled upon bulk, increasing numbers of bugs and vulnerabilities arise which require, you guessed it, more upgrades.

Modularized Information Environment (MIE) is a Web-based information management tool designed to meet the needs of small or medium sized organizations.

Modularized Information Environment implements user authentication, storage of settings in a database, multi-lingual support and a presentation layer API that always generates well-formed XML.

Greenfoot is an integrated development environment that makes it easy to write games and simulations in Java.
It comes with a broad range of demo scenarios and documentation that gets newcomers started very quickly. Greenfoot may be used to learn or teach programming, or just to write a cool game and maybe put it up on a Web site. (it can export the game to a Web page).
The project was originally developed for school age learners, but is now used by all age groups.

Multimedia Converter project provides graphical environment to take full advantage some of the possibilities the ffmpeg and MPlayer.
