Gnaural is a multi-platform programmable binaural-beat generator, implementing the principles described in October 1973 Scientific American, Gerald Oster, "Auditory Beats in the Brain."

There has been considerable research done on the subject since that publication, and Gnaurals Windows-based predecessor, WinAural, has been used as the audio stimulus in at least one published study, "The Induced Rhythmic Oscillations of Neural Activity in the Human Brain", D. Cvetkovic, D. Djuwari, I. Cosic (Australia), from Proceeding (417) Biomedical Engineering - 2004.

The central finding of Osters article: brain activity can be entrained to the auditory beat frequencies created when each ear is presented simultaneously with tones of slightly offset in frequency. My interest has been exploring how this effect (known as "frequency following response" or "brainwave entrainment") can be used to explore mental states, ranging from profoundly meditative to highly alert.

What are auditory binaural beats?

In 1839, German experimenter Heinrich Wilhelm Dove discovered that playing two tones simultaneously, one in to each ear, induced the perception of a "beat frequency" when the tones were of slightly differing frequency (generally less than 100 Hz apart).

While an acoustic mixing of the two tones will also produce a beat frequency, what is notable about auditory binaural beats is that there is no acoustic mixing of the tones: the beats exist solely within the auditory system. Some researchers believe that they are an artifact of the "neural wiring" used to spatially determine the origins of sounds in our environment.

Gerald Osters breakthrough in 1973 was to observe that the neural processing associated with binaural beats can induce an overall entrainment of brainwave activity (essentially, an oscillation between the two hemispheres in sync with the beat frequency). The neurology of this phenomenon is, according to Oster, tied to the contralateral integration of auditory input taking place in the superior olivary nucleus in the brainstem.

My main interest in the principle has been the possibility that brainwave entrainment can be used to target specific mental states. Gnaural has a long lineage, starting with a DOS program in the mid 1990s, progressing to WinAural for Windows and (in the hope a making a cross-platform solution) BrainJav for Java, and finally the truly cross-platform solution in Gnaural. In over a decade of experience with the technique, I have mainly found it useful for slowing-down brain activity. In that capacity, it has served me in areas ranging from stress reduction, sleep make-up, and particularly as a sort of "poor mans meditation", requiring almost no effort to achieve states of mind that I usually have found rather hard to achieve with real meditation.

But these are strictly my observations, and I make no guarantees about what the technique can do for anyone else. Some of the more unusual applications Ive heard about for my software include sustaining a heightened mental focus for online tournament gaming, and enhancing flotation-tank and related sensory deprivation environments. Many people also apparently use the technique to study more effectively.

One of the stranger facts regarding binaural beats is their seeming ability to be equally-at-home in the laboratory setting as in "grass roots" contexts (such as alternative medicine and the New Age phenomenon). That there is a grass-roots enthusiasm (easily demonstrated by googling binaural beats) is probably related to the sense of promise inherent in an easy-to-implement technique offering the possibility of direct influence of brain behavior. But from a scientific standpoint, there is a big gap between claims (of what binaural beats can do) and corroboration (by scientific method), which has led to a sense in many that the actual subject of binaural beats is "controversial." But this is an irrational response, given that the actual scientific/laboratory basis of binaural beats has remained an established part of the scientific literature for over 30 years.

One of my goals in writing Gnaural was to implement the binaural beat principle within the bounds of my understanding of the established scientific facts regarding the subject. To some extent, this has meant leaving-out many of the "bells and whistles" prevailent in other implementations. That my software has been used for at least one published "hard-science" study suggests that it has been somewhat successful. However, I also hope that Gnaural proves useful for people who wish to explore subjective areas unfettered by scientific rigor. In a subject dealing with matters of the mind, I see both sides -- "grass-roots empiricism" and "scientific empiricism" -- as being complementary halves of a complete investigation of the possibilities, and ultimately, Id hope to see the two sides of our culture be catalysts for each other, rather than inhibited by a mutual antagonism.

Aklabeth project is a remake of the original Ultima.

Aklabeth is a rewrite of Richard C Garriotts Ultima Prequel. Like Ultima 1 to 5, it features a mixture of wandering through (sort of) 3D dungeons, monsters, and tasks to complete.

This game is a port, written in a mixture of C and C++. I wrote this a year or two back, cant remember why, in C. I glued it to my SDL wrapper library and released it.

Its a RPG - sort of. You wander the top world, visit 3D (sort of) dungeons, beat up monsters and perform tasks for the legendary Lord British (AKA Richard Garriott).

Keys:

N S E W (and arrow keys) move player both in upper world, and in the dungeons.

A - attack
I - inventory
Q - quit
X - enter town/shop/dungeon/climb up and down.

Jackbeat project is an audio sequencer with support for the JACK Audio Connection Kit.
Featuring a drum-machine-like interface, it is designed with real-time operation in mind: while playing, the pattern can be edited, the BPM rate modified, and new samples loaded.
The number of tracks and beats is virtually unlimited, and though it is simple, it becomes a powerful tool when connected to other JACK applications providing mastering, effects plugins, etc.
Main features:
- drummachine-like interface for fast and easy editing
- realtime operation : while playing, the sequence can be edited and resized, the bpm rate modified, and new samples loaded,
- virtually unlimited number of tracks and beats
- easy to use and yet powerful : just JACK it into jack-rack and you can apply LADSPA effect plugins on a per track basis, perform mastering with jackeq , etc...
- loads and saves .jab files, Jackbeats file format, based on xml and packed with tar,
- unique masking feature : allows to insert silences with precision into a given track.

Marbles is a simple board game. The objective is to take out as big groups of marbles as possible. Highscore system included. Ive also programmed some simple physics to make it look like the marbles fall.

If you hold the mouse over a cluster of marbles for a little while, then the potential score will show. You get bonuses if you remove eg. all the blue ones.

Installation:

./configure && make

su

./install_marbles.sh

exit

(Dont use "make install", if you did do a "make uninstall")

Start it by typing:

marbles

Its not programmed in QT, but it works in KDE.

Current record:

25960 points
- Held by a friend. Dont think anyone will beat that in a while:)

The key to success for a web site is good search engine ranking. All of the major search engines use link popularity to determine how well a site will rank - so the more high quality, relevant links that lead to your site, the higher it will rank. LinkMachine makes it easy to get the links you need by helping you establish hundreds of quality, relevant link exchanges.
LinkMachine will help you:
- Climb to the top of the search engines
- Gain quality links to your site today
- Automate your link management
- Uncover exactly how to beat your top competitors
- Attract thousands more targeted visitors to your site
The most effective way to interest webmasters in linking to your site is by offering to exchange reciprocal links. This is a win-win situation - both of your web sites benefit from new targeted, relevant links.
LinkMachine project helps you build as large a reciprocal link program as youd like. Search engines see all of the new links pointing from other quality, relevant sites to your site, and increase your rank. Note that this is very different from using indiscriminate "link farms", which will give you no advantage with the search engines.
Google recently revealed the secrets of its search ranking technology by filing a patent application. What we found out is that Google values organic link building - link building that progresses naturally rather than appearing artificial. LinkMachine is the ideal tool for building link exchanges the way Google likes them.
LinkMachines InstantLinks system and link search tools allow you to grow your link exchanges gradually and gain links from many different sites. And with LinkMachines Alternate Profiles feature, you can easily benefit from having the links to your site use a diverse variety of anchor text.
