Free hour of power software for linux

Rush Hour Puzzle Solver project is a Rush Hour puzzle solver that illustrates the solution with PostScript.

Rush Hour Puzzle Solver is a small C++ program that reads a Rush Hour board from a text file and produces a nice PostScript file that shows the shortest solution.

PowerTop project detects which Linux programs and kernel tunables are resulting in the largest power consumption and use of battery time.
Power usage is a hot topic for computer users everywhere. For some, its a matter of how long a laptop lasts without being plugged in. For others, its controlling the temperature of hundreds of systems within a datacenter. For all of us, its about keeping the electricity bill under control and being kind to the environment.
Getting your computer to use the least amount of power can be problematic. This site provides information on reducing power usage, tips, and tricks for Intel-based computers running Linux*.
As a first step, Intel is releasing PowerTOP, a tool that helps you find what software is using the most power. By fixing (or closing) these applications or processes, you can immediately see the power savings in the tool. Youll also see the estimated time left for battery power if you are running a laptop. The Tips&Tricks page has fixes for a lot of the issues that are already found. Join our mailing list to participate in this effort to get Linux to use less power.
Building:
Just type make and then run the program...
tar -zxf powertop-1.1.tar.gz
cd powertop
make
./powertop
Enhancements:
- This release shows P-states (frequencies).
- A suggestion to disable TV-out and to disable Wake-On-LAN for unused ethernet has been added.

KMail Power Tools is meant to be a suite of enhancements to KMail and may be other mail user agents.
It is currently composed of only one (perl) script that acts as a filter (take input from stdin, outputs the modified mail to stdout), adds dialog boxes to kmail, and allows the user to:
- remove all attachments from an email (no user interaction),
- remove selectively attachments, after asking the user,
detach (i.e. save then remove) any attachment to a directory chosen by the user,
- hence reducing the size of your mailbox, while allowing you to backup important attached files.
All these actions are logged within a sentence in the mail body (see below).
Note: removing and detaching is already supported by Thunderbird, but my favourite mailer program is KMail, then...
How it works
KMail allows the definition of filters (like any other email program), but you can define filters:
- which are launched manually,
- which can be programs reading your email on stdin and outputing the result on stdout (or "pipe through").
So I had the idea to use this in order to enhance KMail, and allow it to remove and detach attachments: kmailpt will read and interpret the email (thank you Perl MIME::Parser), then depending on the command line switches, popup a dialog box to ask the user for a directory where to save attachments, and ask him which attachment to remove/detach (thank you Kdialog!).
Also, the sentence "[Attachment removed by jice (26/02/2007 20:33:01): bill.zip]" will be added to the mail body. When you detach an email, it will add a similar sentence, and if the mail body is html, you will even get a link to the new location of the file: "[Attachment saved by jice (26/02/2007 20:36:17) to heavenly.gif]", on which you can even click in order to view the detached file. For text/plain messages, the sentence will be something like: "[Attachment saved by jice (26/02/2007 20:36:17) to file:///home/jice/Images/heavenly.gif]" (unfortunately, although kmail renders http:// or ftp:// urls as links, file:// are not (yet?) - I should enter a bug on bugs.kde.org for this...).
Should you want to know the currently available command line switches, here is the help:
Usage: kmailpt [options]
kmailpt takes an email on stdin, performs actions based
on this mail, then output an email on stdout.
Without any option, it will remove any file attached.
Options:
-d detach the attachments (save and remove)
-q ask which attachment to remove
-h prints this help

CryptoServer is OpenSource Server-side cryptography tool and run as daemon.

It is already tested in very busy environment and can support over one million transaction an hour.

CryptoServer accept the GPL License and can use it for any purpose as is.

Data Architects, DBAs, Analysts and Designers rely on Data Modeling tools to facilitate and simplify their data Modeling efforts, while maximizing the use of their resources. The Power*Architect allows these busy highly technical resources to perform this most intricate part of their job in a fraction of the time.
Power*Architect project is an innovative Java-based data modeling tool geared specifically for Data Warehouse and Data Mart design. It allows the designer to open multiple concurrent source Database connections, create and explore profiles of the source data, drag and drop source schemas, tables and columns into the data modeling playpen, and forward engineer the resultant target database and its associated ETL template.
Main features:
- Access any JDBC or ODBC accessible source database
- Quickly create profiles of source data, including information about the size of the data in each column, maximum and minimum values, frequency distribution of values in a column, and more.
- Profile information is saved with the project, so profile data can still be used to aid off-site design sessions when it is not possible to access the source databases.
- Design the target database Data Model (Data Warehouse)
- Compare the database structure of any two databases highlighting the structural differences and generating the required DDL to synchronize
- Compare the Data Model data structures to an existing target database
- Save a snapshot of all source systems data structures in the project file, allowing data warehouse designers to evolve their target data model remotely
- Forward engineer to Oracle, SQL Server, DB2, and PostgreSQL and more.
- Forward engineer ETL Templates containing source-to-target data mappings
- Invoke ETL Engine to load initial set of data into the target database
- Enable easy centralized installation and updates to many end users (Supports Java WebStart technology).
- The Power*Architect can open multiple source databases concurrently, even if they are from competing database vendors. Another key feature of the Power*Architect, that sets it apart from other data modeling tools, is that it remembers the origin of each column, and is capable of automatically generating the source-to-target data mappings.
- Whether youre building or maintaining your Data Warehouse data model, the Power*Architect will provide you a complete view of all required database structures and will expedite every aspect of your data warehouse design.
- Design your Data Warehouse in a fraction of the time with the Power*Architect.
- We look forward to showing you how!
- The Power*Architect is available now for download! The product is available for free to individuals for personal use. Commercial licensing and support are available at competitive prices. Please call us at 1-866-SQL-POWR to purchase.
Enhancements:
- This release fixes a bug that caused corrupt project files to be saved.
- The handling of automatic cascading primary keys in multi-level identifying relationships now works better.
- The profile manager is now even more stable.
- It is now possible to add new database connection types from within the GUI.

King of the Hill project is a full client/server multiplayer artillery game in the scorched earth tradition.
King of the Hill (KOTH) is an artillery game in the grand old tradition of little tanks with ridiculously powerful weapons trying to blow each other up while trying to avoid getting blown up themselves.
Koth features LibGGI for fast portable graphics, full client/server multiplayer, a few cool weapons, in-game chat, and nice terrain generation algorithm.
Open source in the hopes that others will help out and make this a really great game.

- Supports up to ten players at once, with unlimited observers (ten only because beyond that the game would get unwieldy, not an architectural limitation)
- Players can join and leave at any time without disrupting the game
- Pregame and In-game color-coded chat
- Buy and sell various types of neat weapons to use against your enemies
- Fractal-tessalation terrain generating algorithm produces endless variations of interesting terrain (before you start blowing massing craters into it that is
- Falling dirt and falling damage to tanks
- Lightweight, asynchronous networking protocol - perfectly playable on a modem over the Internet even with high pingtime

- bugfixes and other misc changes (weapons price, power, behavior etc)
- weapons name in death messages
- New explosions
- Koth is now playable on fast computers (sleep in animations)

Simple PHP-based forum, it uses MySQL database to store messages. It supports threads and can be installed from the browser. This is an example of a program written in an hour.

Simply open file forum.php in the browser and follow instructions.

This small application sits in your KDE system tray and patiently checks your BlogLines account (provided you gave it one) for updates in specified periods, half an hour being the default.
It can notify you of new updates in a variety of ways:
- play a sound
- pop up a balloon
- change the tray icon
The icon will always change its color and remain this until you left-click it. Doing so will bring up a konqueror window with the updates url and drop the flag. Other notifications can be turned off.
Enhancements:
- Replaced own icons with BlogLiness.
- Added User-Agent identification.
