Free high availability environment software for linux

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.

- 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.

The Linux Replicated High Availability Manager (aka Linuxha.net) allows the creation of clusters for application high availability through data replication.
Currently, clusters are limited to two nodes, but multiple applications can be hosted and failed-over between the nodes. The software uses DRBD to provide the data replication facillity.
Although this shared-nothing type architecture is typically more complex to configure and manage the Linuxha.net toolset attempts to manage much of this complexity for the administrator.
Much of the initial development and testing took place on various Linux 2.4 based distributions. More recently development and testing has taken place on Linux 2.6 distributions (primarily Fedora Core), ensuring the product works as expected on the latest available distribution releases.
Much effort has been spent ensuring that significant levels of support documentation is available. The documentation section now contains several guides as well as a user manual.
Please note that the user manual will eventually be replaced by a reference guide and various installation and user guides. Keep changing the documentation page regularly - these will be added when they are completed and aim to just cover specific topics.
Enhancements:
- Improvements were made to handling physical network link checking.
- Improvements were made for local IP fail-over.
- More flexible cluster partitioning handling was implemented.

AntiRight Desktop Environment is a lightweight and scripted desktop environment that uses the Motif toolkit. Development is carried out with a minimalistic philosophy in mind.

The software consists of a text editor, a desktop panel, a sticky note utility, system management panels, a file manager, a calculator interface, a color/background selector, a command launcher, a simple help system, an email and Web browser launcher, a theme selector, a preferences utility, a series of system monitors including a graphical load meter, and a CD player.

The desktop panel consists of launcher icons, a launcher panel button, a screen lock button, a virtual desktop switcher, an alarm utility, a command launcher, a clock, a user counter, a load meter, and a mail checker.

Techisa Desktop Environment is a lightweight alternative desktop environment developed using Qt.
The projects goal is to provide users with a comfortable environment using as few resources as possible. Only a Brazillian Portuguese translation is currently available.
Enhancements:
- Better support for KDE desktop files.
- Improved recognition of KDM/GDM sessions.
- New icon search paths.
- Enhancements to the TDE menu.
- Better handling of links and properties.
- TDESU shows correct error codes.
- Thumbnails.
- A tree view in the file browser. tdeopen accepts new parameters: [file name] directly executes a file or associated application, and -f [source] [destination] shows a popup allowing user to copy, move, or link.

High Visibility Calculator is a high visibility calculator for people with disabilities.

Large buttons with bold text are easy to push for people with motor control or vision problems.

OpenWindows Augmented Compatibility Environment (OWacomp) makes it possible to use the older OpenWindows Deskset environment on Solaris 9 and 10. OpenWindows Augmented Compatibility Environment is also useful for people that need to compile XView, OLIT, or DevGuide applications.
If you are using Solaris 9 or Solaris 10 and you are missing the older OpenWindows Deskset environment, then these packages are for you! If you need to compile XView/OLIT/DevGuide applications on either Solaris 9 or Solaris 10 then these packages may be of some help as well.
Supported Systems:
- Solaris 9 for Sparc and i86pc.
- Solaris 10 for Sparc and i86pc.
What is included:
OWacomp is mostly a re-packaged version of:
- Solaris 8 OpenWindows SUNWol binary packages and patches.
- Extra XView tools used by the author over the years and that others might be interested in. (olvwm, dumptool, disktool, rootmenu, etc..). Suggestions are welcomed if youd like to see this list expanded.
What is not included:
- The source code to the original OpenWindows binaries is (c) SUN Microsystems Inc. and is not available. Please note that the author never had access to that source code and as such the rebuilt packages are only what they are: rebuilds of packages consisting of packaged binaries built by SUN Microsystems Inc.
- The source code to some of these applications (dumptool, rootmenu) is under NDA with the author and will not be provided.
- The source code to the other applications (xvset, olvwm, pantool, disktool, etc...) is available in the SUNWolsrc package. (Release 1.0b3)
Enhancements:
- This release adds /usr/openwin/lib/checkOW for sparc and i386.
- It adds the Makefile.gcc missing from the olvwm 4.5 source.
- It rebuilds olvwm under Solaris 9/SPARC instead of Solaris 10/SPARC (libm.so.2 vs. libm.so.1 mismatch).
- This fix isnt complete for Solaris 9/i386 yet (olvwm is fine, but other binaries arent).

Zirconium Desktop Environment is a new low resource desktop shell optimized for usability.
Zirconium Desktop Environment operates on the philosophy that the desktop environment needs to stay out of the users way and provide the quickest access to the functions that are truly needed from a desktop shell.
Principle Zirconium Desktop Environment design goals:
- Very easy navigation by taking advantage of the corner effect by placing the icons for the 2 most critical functions (program launcher and window switcher) in the top corners.
- Minimal use of on-screen real estate. This is accomplished by "recycling" the window title bar by overlapping the already minimal on screen furniture on top of the title bar when a window is maximized.
- Eliminating the "system tray". Instead of using a pixel wasting systray icon to communicate status to the user programs are expected to use the ZDE Notification Daemon to sent small unobtrusive notifications to the user when something of note occurs. The ZDE Notification Daemon uses the SOAP protocol for universal compatibility and network transparency.
- Web integration. An (optional) backdrop manager based on the embedded Gecko engine from Mozilla is provided to provide for "Weblets" to run on the desktop. The ZDE session manager also provides a SOAP API that can be accessed by signed or expressly permitted Weblets to access the ZDE system.
Components of the ZDE system:
Corner Menus.
The left corner menu opens up the Program Launcher. Note that the Program Launcher is a custom navigation window and not a pop-up style menu. The Launcher window closes when an item is activated or the mouse pointer leaves the window.
The right corner menu is a list of open windows for window switching. It is a standard GTK pop-up menu.
Mini-Bar.
In the top center is the Mini-Bar that shows essential items like the time, volume control, battery and network status. The Mini-Bar is the same height as the Title Bar of a window so that when a window is maximized the title bar is partly covered by the Mini-Bar.
Notification Daemon:
When a SOAP message for a Notification arrives the Notification pop-up appears briefly. When not shown the very edge is visible in the lower-right. Mousing over the edge makes the Notification appear again and the mouse leave event closes the notification making it very simple to dismiss a notification by just mousing over it. Clicking the visible edge will open a Notification History window showing all notifications that have been logged during the session.
Window Theme:
The Window Manager theme needs to make special allowances for the way ZDE is arranged. The title bar needs to be 22 pixels high and the controls need to be 22 pixels away from the ends of the title bar to allow for the corner icons.
