Easy Funktion is 2D function plotter software with an equation solver. Easy Funktion has an office-like GUI frontend and features a built-in pocket calculator, calculating with complex numbers (with special extensions for electronics, e.g. capacitor/inductor impedance), a function to export to spreadsheet software, and an advanced formula editor with automatic formatting.
This program alternatively supports an english version of the GUI, but at this time there is no separate english language download available.
In order to activate the english language GUI, do the following:
Open the folder where the program data is installed (/usr/share/easyfunktion). Rename the subfolder de to de_. You may need the root account to do this.
Enhancements:
- Unicode support for Unix.
- An English language GUI with English online help is now available for non-German installations.

Easy SVN is a subversion browser via the Web. Easy SVN Browser is easy because only a command line svn program and Perl are required to run it; no extra software needs to be installed. After configuring the Perl script as cgi-bin program, SVN repositories can be navigated, and entries viewed for contents, history, and diffs.
Installation:
Follow these steps for a quick installation of web-svn-view:
1. Log in as the user who is running the webserver (e.g., www).
2. As this user, make sure you have read-access on your repository. Issue an svn command to make sure that if necessary, you are prompted for a username and password. Once the viewer is running, logins must take place automatically.
3. Obtain web-svn-view by getting the archive http://public.e-tunity.com/web-svn-view/web-svn-view-latest.tar.gz . Save the archive on your disk as e.g.
/tmp/web-svn-view-latest.tar.gz.
4. Change-dir to a directory where the webserver will run the viewer.
5. Unpack, using tar xzf /tmp/web-svn-view-latest.tar.gz. Note the full paths to the contained directories cgi-bin, css and img. In the following example well assume that the base directory is /Users/e/src/e.
6. Edit cgi-bin/web-svn-view and modify the configuration variables at the top of the file. The variables are documented in the script.
7. Edit the servers configuration file. E.g, for Apache, edit httpd.conf and add the following lines:
ScriptAlias /svnbin /Users/e/src/e/web-svn-view/cgi-bin
Alias /svncss /Users/e/src/e/web-svn-view/css
Alias /svnimg /Users/e/src/e/web-svn-view/img
< Location / >
Order deny,allow
Deny from all
< /Location >
< Location /svnbin >
Order allow,deny
Allow from all
< /Location >
< Location /svncss >
Order allow,deny
Allow from all
< /Location >
< Location /svnimg >
Order allow,deny
Allow from all
< /Location >
You will need to supply the right directories for your system.
8. Restart the webserver.
9. Point your browser to http://yoursite/svnbin/web-svn-view.
Enhancements:
- The configuration settings in cgi-bin/web-svn-view can now be overridden by environment variables.
- That makes it possible to re-use the same SVN browser to view many repositories, based on environment variables passed by the Web server.
- The documentation was updated with an example.

Prey tells the story of Tommy, a Cherokee garage mechanic stuck on a reservation going nowhere. His life changes when an otherworldly crisis forces him to awaken spiritual powers from his long-forgotten birthright. Abducted along with his people to a menacing mothership orbiting Earth, he sets out to save himself and his girlfriend and eventually his planet.
Prey is serious, dark story, based on authentic Cherokee mythology. Themes of sacrifice, love and responsibility are explored and the story dives into emotional territory not yet explored by similar games. You will find nothing familiar with this game.
Overview
In Prey, gamers enter an unpredictable world where nothing can be taken for granted. Most of the game takes place within a living ship, a giant entity that can sense and react to Tommys presence.
Prey makes use of Josephs Campbells renowned story structure, "The Heros Journey," for guiding the main character arc. Campbells extensive work on mythological story progression was made famous when George Lucas used it for Luke Skywalkers story arc in the original Star Wars.
Main features:
- Built on an enhanced Doom 3 engine, the most impressive 3D engine used in a released game.
- Portal technology adds a new dimension to gameplay, allowing enemies to appear out of thin air and create new and completely original puzzles and gameplay styles.
- Several never-before-seen gameplay elements such as Spirit Walking, Wall Walking, and Deathwalk.
- Highly organic, living environment that itself can attack Tommy.
- A deep, emotional story of love and sacrifice.
- Tommy has a sidekick, a spiritual hawk that can help him fight enemies and decipher the alien language of the living ship.
- Multiplayer game support that takes advantage of the unique gameplay styles in Prey.

LastamaroK allows to play last.fm radios ( http://last.fm/ ) in amaroK, and to use some basic controls as love/skip/ban.

LastamaroK can be integrated in both Konqueror and Firefox.

More informations about using LastamaroK are in the Readme.

LastamaroK is based on the lastFMProxy by Vidar Madesn ( http://vidar.gimp.org/?page_id=50 ).

Ubercart project is an e-commerce shopping cart integrated with the Drupal CMS.
Main features:
- Configurable product catalog includes catalog pages and a block to display product categories.
- Flexible product creation system. Create normal products by default. Create product classes to store more information on a subset of your catalog. (Ex: Creating a book class would let you store and display separately the author, publisher, and length of the book.)
- Flexible product attributes system. Create user selectable attributes for your products that modify the price, SKU/model, and/or weight of items as the customer adds them to his or her cart.
- Single page checkout. All checkout information gathered on a single screen composed of configurable checkout panes. Third party modules can define checkout panes to replace or add to the default set, making it easy to customize the checkout experience.
- Automatic account generation (anonymous checkout). Accounts and emails are automatically generated based on the customers e-mail address. For return customers, previously used addresses will be listed on the checkout page for easy access.
- Simple order processing. The order administration screens have been designed by and for our salesmen. We believe there is always room for improvement and will try to make it happen! Order screens use the "pane" model, so the screens are configurable and extensible to accommodate a wide variety of e-commerce applications.
- Simple order creation and editing. Easy to create orders manually for customers, adding products, shipping prices, etc. from a single screen. Line items system makes it easy to add fees, discounts, and coupons to orders.
- Integrated payment system that acts as a bridge between acceptable payment methods (check, credit card, cod, etc.) and payment gateways (Cyber Source, Authorize.net, PayPal, etc.). Configurable payment processing and tracking, and easy to use credit card terminal with varying levels of access.
- Activity logging. Enable logging to see all the changes made to an order, including payment processing. (Your accountant will love this!)

Python is an interpreted, interactive, object-oriented programming language. Python is often compared to Perl, Tcl, Scheme or Java.

Python combines remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems (X11, Motif, Tk, Mac, MFC). New built-in modules are easily written in C or C++. Python is also usable as an extension language for applications that need a programmable interface.

The Python implementation is portable: it runs on many brands of UNIX, on Windows, OS/2, Mac, Amiga, and many other platforms. If your favorite system isnt listed here, it may still be supported, if theres a C compiler for it.

The Python implementation is copyrighted but freely usable and distributable, even for commercial use.

Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together.

Pythons simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed.

Often, programmers fall in love with Python because of the increased productivity it provides. Since there is no compilation step, the edit-test-debug cycle is incredibly fast. Debugging Python programs is easy: a bug or bad input will never cause a segmentation fault. Instead, when the interpreter discovers an error, it raises an exception.

When the program doesnt catch the exception, the interpreter prints a stack trace. A source level debugger allows inspection of local and global variables, evaluation of arbitrary expressions, setting breakpoints, stepping through the code a line at a time, and so on.

The debugger is written in Python itself, testifying to Pythons introspective power. On the other hand, often the quickest way to debug a program is to add a few print statements to the source: the fast edit-test-debug cycle makes this simple approach very effective.
