Naughts and Crosses a simple tic-tac-toe game - with a twist.
This is a simple tic-tac-toe game, written in C++ for the console. Its a very simple affair, and only suited to the odd five minutes, but has a fully functional one-player mode (which I have tried to make neither too easy nor too hard) and offers the ability to modify the board size.

Cross-LFS 1.0.0
Cross-LFS is a project that provides you with step-by-step instructions for building your own customized Linux system. more>>
Cross-LFS stands for Cross Linux From Scratch (CLFS) and is a project that provides you with step-by-step instructions for building your own customized Linux system entirely from source.
Why would I want a CLFS system?
Many wonder why they should go through the hassle of building a Linux system from scratch when they could just download an existing Linux distribution. However, there are several benefits of building CLFS. Consider the following:
CLFS teaches people how to build a cross compiler
Building CLFS teaches you how to make a cross-compiler and the necessary tools, to build a basic system on a different architecture. For example you would be able to build a Sparc toolchain on an x86 machine, and utilize that toolchain to build a Linux system from source code.
CLFS teaches people how to utilize a multilib system
CLFS takes advantage of the target systems capability, by utilizing a multilib capable build system.
CLFS teaches people how a Linux system works internally
Building CLFS teaches you about all that makes Linux tick, how things work together and depend on each other. And most importantly, how to customize it to your own tastes and needs.
Building CLFS produces a very compact Linux system
When you install a regular distribution, you often end up installing a lot of programs that you would probably never use. Theyre just sitting there taking up (precious) disk space.
CLFS can be built from most Unix Style Operating Systems
You can build CLFS even if you dont have Linux running. Our build instructions have been tested to build from Solaris and the BSDs.
CLFS is extremely flexible
Building CLFS could be compared to a finished house. CLFS will give you the skeleton of a house, but its up to you to install plumbing, electrical outlets, kitchen, bath, wallpaper, etc. You have the ability to turn it into whatever type of system you need it to be, customized completely for you.
CLFS offers you added security
You will compile the entire system from source, thus allowing you to audit everything, if you wish to do so, and apply all the security patches you want or need to apply. You dont have to wait for someone else to provide a new binary package that (hopefully) fixes a security hole. Often, you never truly know whether a security hole is fixed or not unless you do it yourself.
What can I do with my CLFS system?
A by-the-book CLFS system is fairly minimal, but is designed to provide a strong base on which you can add any packages you want. See the BLFS project for a selection of commonly used packages.

Red Hat Linux 9
Red Hat Linux is probably the best-known Linux distribution. more>>
Red Hat Linux is probably the best-known Linux distribution. Red Hat Linux is well-supported by commercial software, and tends to be easy to install and have good hardware support out of the box.
Compaq has taken over the maintenance for Red Hat for their Alpha processor - theres a link to their Alpha Red Hat page below.
Red Hat 9 is the last version of Red Hat Linux per se, and Red Hat will stop supporting it soon. Instead they offer a commercial Linux distribution, "Red Hat Enterprise Edition", and a free distribution, "The Fedora Project".

Because it is open source , it can integrate with any system. Because you can use it as a web page , command line or XML- WebService , it will work with most languages , including Java , Perl , C#/.Net and PHP. As a Java based program , it will run on any platform including Windows , Linux / Unix and Mac.
Main features:
- Personal Search Engine for your Desktop (Windows , Linux and Mac).
- Intranet Search Engine - Search your Company or College Intranet.
- Part of your Development Project - Have search abilities up and running in a few minutes.
- To provide Search facilities on your website.
- As a P2P search engine.
- In conjunction with a wiki, as a knowledge / document management solution.
- Scan a set of websites for the data you want (e.g. Search Job sites on a hourly basis).
- Explore the Semantic web using RDF.
- Search RSS feeds for the information you want.
- Search your Companies systems (including SAP , Oracle or any other Database / Data source).
- Provide a back end for searching in your App (Web , Swing , SWT , Flash, Mozilla-XUL, PHP , Perl or even c#/.Net) .
- Document Management for PDF, Word and other Docs.
- As a Webservice to provide search information
- As a command line tool , to give searching power to your scripts.
- Provide a Search facility for your project documentation.
Using
To use Red-Piranha - open your favourite web browser and point it at http://localhost:8080/RP . Within a few seconds , you should see the Red-Piranha start screen. This will have three items of interest
- A Text box , where we enter the information to add or search
- An add information button - to tell Red-Piranha about new information
- A Search button - to carry out a search.
Before we can search , we must tell Red-Piranha we information we are interested in. This is as easy as putting the piece of information we want to add (e.g. the folder c:temp) in the search box and pressing the Add information button. A message will be displayed saying that your information is being added and will be available to search shortly. For more information , look in the logs at TOMCAT_HOMEWebappsRPlogsrp.log
Examples of things we can add to Red-Piranha are
- A folder (e.g. C:Temp). All files in both this folder and *all* its subfolders will be added.
- An individual file. This file can be text , a web page , a word document , or pdf document. For binary files (like word , which are not plain text) , Red-Piranha will scan the file for recognizable text and add that.
- A Web page. Red-Piranha will add this web page , *and* web pages it links to.
- A Google Search (e.g. http://www.google.com/search?q=some+thing?m=100). Red-Piranha will get the results of the google search , and add information on the pages it links to.
- An XML file (including RSS feeds) , either on disk or over the web.
- Favourites / Bookmarks folders - Red-Piranha will index the web pages that these favourites point to.
Adding information can take anything from a few milliseconds , depending on the amount of information being added. Once added, Red-Piranha will check on a regular basis to see if the information added has changed and re-index if required. Your information is now available to be searched.
To do a search , put the item you want to search for into the textbox and press search. Red-Piranha will show the search results on the screen. Clicking on the link beside the search results will show you the original information (as long as you have access to it).
From version 0.3 onwards , Red-Piranha can learn what search results you are interested in an improve your future searches. To give Red-Piranha feedback and help it learn what you are interested in , click on any of the links on the search results page. Red-Piranha makes a note of your choice , which is used to adjust the search results later.

AVR Cross Development Kit 20060719
AVR Cross Development Kit is a cross development kit for the AVR RISC processor. more>>
CDK4AVR stands for Cross Development Kit for Atmels AVR RISC processor serie and should support your development with a comprehensive Assembler and C development environment for even this processor familie under Linux. It will present only free of fee tools, so you can use it without risks. Further you will find some useful OS projects and related sample code all arround AVRs inside of the example packages.
CDK4AVR collects all programms and development tools in one directory (/opt/cdk4avr) and will try to present an easy to admin installation.
My intention for CDK4AVR is / was to provide a full featurd tool chain distribution of all the free accessible resources, because the most stuff is scattered to the wide of the whole Internet and only compileable by wizards or professions.
Installation:
Each package will be provided as RPM only. It is not necessary to install all packages,but you have to install the base package cdk-avr-base every time you want to use another package. Here is an example for a typical GNU development environment:
[user@host]$ rpm -hiv cdk-avr-base-0.3-20031111.i386.rpm
[user@host]$ rpm -hiv cdk-avr-binutils-2.14-20030906.i386.rpm
[user@host]$ rpm -hiv cdk-avr-gcc-3.3.2-20031021.i386.rpm
[user@host]$ rpm -hiv cdk-avr-gcc-c++-3.3.2-20031021.i386.rpm
[user@host]$ rpm -hiv cdk-avr-gcc-colorgcc-3.3.2-20031021.i386.rpm
[user@host]$ rpm -hiv cdk-avr-libc-1.0.2-20040229.noarch.rpm
[user@host]$ rpm -hiv cdk-avr-gdb-6.0-20031019.i386.rpm
[user@host]$ rpm -hiv cdk-avr-simulavr-0.1.2.20040304cvs-20040304.i386.rpm
[user@host]$ rpm -hiv cdk-avr-avarice-2.2-20040229.i386.rpm
[user@host]$ rpm -hiv cdk-avr-uisp-20040207cvs-20040304.i386.rpm
[user@host]$ rpm -hiv cdk-avr-avrdude-4.3.0-20040229.i386.rpm
Base package -- is needed every time you will use any CDK4AVR package.
NOTE: Users of base packages with version 0.2 and prior have to update to latest version. There was a damaged (t)csh startup script. As a result of an buggy %preun script in previous packages you have to update in two cycles:
[user@host]$ rpm -hUv cdk-nios-base-0.3-20031111.i386.rpm
[user@host]$ rpm -hUv --force cdk-nios-base-0.3-20031111.i386.rpm
Enhancements:
- There are minor feature enhancements in AVR-Ada 0.4.1.
- As a result, the packeges for binutils and gcc/gnat were rebuilt.
- There are new packages for the AVR-Ada run time system and related examples.

Snoopy vs. the Red Baron is an open-source one/two player combat game, available for Mac OS X, Linux, BeOS, QNX and Windows.
The original Snoopy was a tiny game for the Apple Macintosh, with black and white graphics, but already almost all the levels of the new Snoopy/SDL were implemented.
Snoopy could be played by two opponents, sharing a single screen and keyboard, and although it had poor graphics and tough controls, we very much liked to play it.
While we learned programming, we constantly sought for simple, yet interesting projects. If you have ever tried to learn a new language or API, you will have recognized that the simplest way in mastering the stuff is simply reprogramming an existing application, without losing much thought on design and originality.
So my friend reprogrammed Snoopy, in Object Pascal, using SAT, the Sprite Animation Toolkit, on his Classic II. That version of Snoopy features a fully functional AI, network play, but only the first level ( weapons drop).
While he was at it, he also implemented a "missing feature", the bombs, for which there where graphics and sounds in the game, but which could not be thrown.
When I discovered SDL, I recognized that it would be ideal for the job. Running on Windows, Linux, MacOS, BeOS and many other platforms, it is my new toolkit of choice for multimedia programming. It took us several weeks to port Snoopy (besides going to school, but now the work is almost done, with only the finishing touches to be made.
I can only encourage everyone to try SDL; it is really easy and portable (if worked right).

SIMD Cross-platform headers 2004.10.26
SIMD Cross-platform headers is a cross- platform, cross-compiler, cross CPU C/C++ header collection. more>>
SIMD Cross-platform headers is a cross- platform, cross-compiler, cross CPU C/C++ header collection that aids the creation portable vectorized (SIMD) C/C++ code.
SIMD Cross-platform headerst supports (or partially supports) x86 (MMX/SSE/SSE2) GCC and MSVC, PPC Altivec GCC and CodeWarrior, ARM GCC, and software-emulated SIMD.
NOTE: Code must be 16-byte aligned. Align to 16 when allocating memory.
X86/XSCALE (Intel) vs. PowerPC/MIPS
While the PowerPC and MIPS SIMD instructions take 2 source vectors and a destination vector, the Intel platforms only take a source and destination. Example:
PPC/MIPS can do:
C = A + B
X86 can only do:
A = A + B (or A+=B)
Code written either way will work on the X86, and still be faster than 387 math, but preserving the registers takes significant overhead (Disassemble the test program for an example. The prints preserve, the disassembly test does not.) For the fastest code between systems, write your SIMD math as the X86 expects, manually preserving SIMD variables.
At least GCC for PPC doesnt seem to have any issues figuring out how to deal with a source and destination memory address being the same.

- Created file with some i386, GCC dialect
<<lessSIMD Cross-platform headerst supports (or partially supports) x86 (MMX/SSE/SSE2) GCC and MSVC, PPC Altivec GCC and CodeWarrior, ARM GCC, and software-emulated SIMD.
NOTE: Code must be 16-byte aligned. Align to 16 when allocating memory.
X86/XSCALE (Intel) vs. PowerPC/MIPS
While the PowerPC and MIPS SIMD instructions take 2 source vectors and a destination vector, the Intel platforms only take a source and destination. Example:
PPC/MIPS can do:
C = A + B
X86 can only do:
A = A + B (or A+=B)
Code written either way will work on the X86, and still be faster than 387 math, but preserving the registers takes significant overhead (Disassemble the test program for an example. The prints preserve, the disassembly test does not.) For the fastest code between systems, write your SIMD math as the X86 expects, manually preserving SIMD variables.
