Free built in wall units software for linux

Qalculate! is a multi-purpose desktop calculator for GNU/Linux. Qalculate! project is small and simple to use but with much power and versatility underneath.
Features include customizable functions, units, arbitrary precision, plotting, and a user-friendly interface (KDE or GTK+).
Main features:
- Redesigned GUI with history view in the main window
- Display of as-you-type expression parsing and function hints
- Enhanced completion
- Scaling of result display to vertically fit the window
- Nicer history listing
- Enhanced result display with much nicer parentheses
- Meta modes
- 67 new units: bel (B) and neper (Np), information units such as bit and byte, many convenience units (km/h, deciliter, etc), and more.
- Binary prefixes
- Some new variables and functions
- Fixed help display in new yelp
- Fixed compile with cln-1.1.10
- Fixed regressions in simplification
- Fixed f(x) return type analysis (ex. log(x) represents a real number if x represents a positive). This was by accident unused.
- ...and many more bug fixes and enhancements...

Globulation 2 is a Real-Time Strategy (RTS) game which reduces micro-management by automatically assigning tasks to units.
The player chooses the number of units to assign to various tasks, and the units do their best to satisfy the requests. This allows the user to manage more units and focus on strategy rather than individual units jobs.
It can be played by a single player, through your Local Area Network [LAN], or over the Internet thanks to Ysagoon Online Gaming (pronounced yog as in yoghurt) - a meta-server allowing transparent interaction between players and the IRC chatters on #glob2 (irc.freenode.net).
Globulation 2 features AI allowing single-player games or any possible combination of human-computer teams. Also included is a scripting language for versatile gameplay or tutorials and an integrated map editor.
Enhancements:
- This release fixes some bugs that crashed the game, and made it hard to play.
- It will hopefully be the last release before a major rewrite takes place.

IPFIRE-wall is an IPv4 Packet Filter with Network Address Translation capabilities. It can be used in desktop systems and in simple network configurations, providing a friendly interface and a simple installation. Also unprivileged users can personalize.
Enhancements:
Kernel: Added support for version 2.6.20.
- Corrected a little bug that used to send in userspace also the packets pre/post routed although the silent modality had been chosen.
User Interface:
- Added a new submenu, accessed by the combination CTRL-B, which allows the user to easily add an address to block by its name. This menu can show the list of blocked web addresses, and provides an interface to add and remove new entries.
- The TCP flags representation has been changed: instead of the full name SYN, ACK, RST, PSH, URG, FIN, the user interface, for the sake of brevity, will now just print the corresponding initial letters, i.e. S, A, R, P, U, F, respectively. The Urgent flag will be printed in dark red color, from this version on.
- The length of the rule name has been extended to support 24 characters instead of the 19 of the previous versions.
Documentation:
- the web documentation is being updated and corrected. This process will continue after this release. Until now, practically the firts 14 topics of the documentation text (see ipfirewall documentation index) has been updated. The remaining pages, together with the new screenshots, are still being revised. Keep an eye on them to stay up to date and be able to use the software at its maximum capabilities.

Optikal project is a tool for generating optical illusions.

Its images can be viewed at any resolution your screen supports, saved for later perusal, or printed for instant wall art.

It arose from frustration with the tiny optical illusion images available on the web, so Optikals images can be viewed at any resolution your screen supports.

They can also be saved for later perusal, or printed for instant wall art.

If you are unable or unwilling to run Java applications, all of the 30 illusions the program supports are available in an online gallery.

DataDrafter project is a new and unique program that allows you to create your own interactive graphics applications with data editing, navigation, search and reporting features built in. Use DataDrafter instead of Visio for example, to create diagrams, maps and technical drawings that are interactive and fully integrated with your data.

Your visualizations become real applications instead of just wall paper. You can even share your graphics and data as an application on the web or on your own intranet.
If you use a combination of drawings and spreadsheets to manage data, try using DataDrafter instead.

The Integrated Data/Graphics Environment ensures that both your data and graphics stay synchronized. With DataDrafter your drawings become an interactive part of your data management process. Why put all that effort into your drawings just to hang them on the wall? Put them to work for you and others while keeping them up to date with DataDrafter.

phpbigbiz is a Web-based MySQL front end that handles acts as a P.O.S. system. The default layout is to add a customer, add units to the customer, then add parts to units.
phpbigbiz is set up for the repair industry.
Main features:
- Expandability
- All pages are remembered
- Easy printing
Enhancements:
- More functions, an install wizard, better printing functions, and an improved printing class were added.
- This is much more flexible for other businesses.

XWelltris project is a 2.5D Tetris-like game. Its aim is to score as highly as possible.

XWelltris is a tetris like popular game.

Imaging that you are looking into the glass from the top. You see four walls and the bottom. The flat 2d figures falling down from the walls one by one. You can move these figures from one wall to another or rotate them.

If the figure leave the wall then it moves on the bottom while another figure is pushed. You need to form full rows and/or columns on the bottom.

When you form such row, it disappear and you receive additional empty space on the bottom and scores :).

The more rows disappear at a time, the more scores you have. If you cant place the whole figure on the bottom, then it stays on the wall and this wall became frozen (you cant place figures on it) for a while.

After nth rows were successfully cleared, you will receive bonus figure and go to to the next level - game speed will be increased. Your task is to play more longer and earn more scores.

The game options allow you to play with two,three,four,five or six piece figures, mix them together, show next figure and switch on rotation of the game board! Try it, its very funny.

Units-filter is a basic standalone filter written in C, flex, and bison.
It inputs strings like "1.5e3 nN.m.s^-1" (which could be the time growth ratio of a torque) and outputs the value in standard SI units, followed by the physical dimension of this value.
units-filter can be embedded in educational test systems, in order to analyze a students answer to a problem of physics or chemistry.
Enhancements:
- The support for quantities with a particular number of significative digits was added.
- For example, the entry "1.02m#5" or "1.0200m" are equivalent and signify a distance measurement precise at the sub-millimeter scale.
- Both would yield the output "1.0200e+00 m".
