MAME: The Emperor's New Clothes

The things they do not want you to see...

Driver-Man's super-binary:

http://www.mediafire.com/file/skcth05nid0txbb/m720c.zip

Vs.

Derrick's nonsensical bloat:

http://www.mediafire.com/file/i2cjpzrcwc4bqvo/Derrick.zip

TESTING: 720 Degrees (Atari Games, 1986)

Derrick's code, summary: flickering sprites bug, analog jittery rotation bug, non-authentic angle conversion algorithm, unnecessary new menu and other bloat, tracking gets off just by using the new menu, without option to re-calibrate the game must be re-started

Driver-man's code, summary: fixed analog jittery motion and flickering sprites bug, new angle conversion algorithm true to authentic operation, simultaneous support of input devices - easy testing, same old familiar interface - no new menus, tracking can be calibrated at any time

(Someone requested Derrick's source code,
not surprisingly message disappeared in a matter of minutes.)

There are, of course, those who do not want us to speak. I suspect even now orders are being shouted into telephones and men with guns will soon be on their way. Why?

Because while the truncheon may be used in lieu of conversation, words will always retain their power. Words offer the means to meaning and for those who will listen, the enunciation of truth.

And where once you had the freedom to object, to think and speak as you saw fit, you now have censors and systems of surveillance, coercing your conformity and soliciting your submission. Cruelty and injustice, intolerance and oppression.

How did this happen? Who's to blame? Well certainly there are those who are more responsible than others, and they will be held accountable. But again, truth be told, if you're looking for the guilty, you need only look into a mirror.

- Are you like a crazy person?
I'm quite sure they will say so.

Voila! In View, a humble Vaudevillian Veteran
cast Vicariously as both Victim and Villain
by the Vicissitudes of fate.

This Visage, no mere Veneer of Vanity
is a Vestige of the Vox populi
now Vacant, Vanished.

However, this Valorous Visitation
of a bygone Vexation stands Vivified
and has Vowed to Vanquish these Venal
and Virulent Vermin Vanguarding Vice
and Vouchsafing the Violently Vicious
and Voracious Violation of Volition.

The only Verdict is

Vengeance

a Vendetta

held as a Votive not in Vain

for the Value and Veracity of such

shall one day

Vindicate the Vigilant and the Virtuous.

Verily, this Vichyssoise of Verbiage Veers most Verbose.

- Can you prove any of this?
Why do you think I'm still alive?

- Oh please, have mercy!

Oh, not tonight Bishop... not tonight!

Those two input handling bits, analog (absolute) and dial (relative), can be put together, and this little piece of code below is the actual algorithm compiled in the binary given for download. It does everything, and more, Derrick's 2MB extra bloat does, only without bugs, faster and more authentic.

ADDENDUM: Who owns MAME?

There are many changes to MAME code which instead of to improve MAME and fix old bugs, they introduce new bugs, bloat and unnecessary hacks. However, we are not allowed to talk about it on MAME World, BYOAC or KLOV forum, they expect you will pretend those bugs and bloat do not exist.

Perhaps Aaron is being paid by Microsoft to introduce bloat and slowdowns in MAME, for whatever reason Microsoft is doing the same with their own software. And as funny as that sounds, or not, the CONTROL of where the project is going, or what submission are accepted, is not openly discussed, it is not subject to public scrutiny nor there is any voting and majority consideration when decisions are made.

Now, everyone knows about David R. Foley affair and supposedly stolen MAME trademark, which lifted up quite some dust and made a lot of people and general public angry, yet in the same time the ownership of far more important MAME assets are not even mentioned or discussed anywhere. -- How did MAME get from Italy to Canada and England? How did control over MAME get from Nicola to some Mr Mark Colgan and some proxy firm called 'contactprivacy'? How is MAME a "public project" if all the decisions are made behind closed doors and everything is controlled by some unknown selected individuals?

Who owns MAME?

With old odd ends, stol'n forth of holy writ;

And seem a saint, when most I play the devil."

ELECTROMAGNETISM: The Simple Truth

2009-11-09T04:58:00.001-08:00

When 2 and 2 come together... it equals 4, and it's that simple.

Photons and wave-particle duality

First, let me equate fields with "particles", and so the smallest amount of electric charge are electron and positron, their filed magnitude describes spherical potential which we somewhat appropriately consider a 'point particle' since it drops off rapidly according to inverse-square law.

http://en.wikipedia.org/wiki/Field_(physics)

The magnitude of an electric field surrounding two equally
charged (repelling) and two oppositely charged (attracting) particles.

Photon, electromagnetic radiation is simply combined kinetics of an electric dipole. When positron and electron interact, initially they will try to stick together - orbit each other, but due to magnetic force acting perpendicularly to both, the velocity vector and magnetic field vector, they will twist around and produce spiral trajectory, or more precisely said - their paths will describe double-helix. This type of wavy movement is also known as transverse wave, so electron and positron do not really annihilate, they actually COMBINE into a photon. Light polarization is then simply geometrical plane of charge oscillation, while superposition explains why photons not have net electric charge despite their evident electromagnetism.

http://en.wikipedia.org/wiki/Pair_production
http://en.wikipedia.org/wiki/Electromagnetic_radiation
http://en.wikipedia.org/wiki/Positron-electron_annihilation

- "Electromagnetic waves can be imagined as a self-propagating transverse oscillating wave of electric and magnetic fields.

http://en.wikipedia.org/wiki/Richard_P._Feynman

- "The fact that the electromagnetic field can possess momentum and energy makes it very real... a particle makes a field, and a field acts on another particle, and the field has such familiar properties as energy content and momentum, just as particles can have"

Magnetic monopoles
right under everyone's nose

EM polarity is a relation between forces of attraction and repulsion, if the field lines are going in two opposite directions we have a dipole moment and minimum of two fields, but if all field lines go in only one and the same direction sharing a common source, then we simply ought to call it a "monopole".

http://en.wikipedia.org/wiki/Amper's_law

MAGNETIC DIPOLE (left) / MAGNETIC MONOPOLE (right)

This monopole fields drops off with inverse-square in the plane perpendicular to its velocity, but it also weakens as the angle aligns with velocity vector according to cross product, so at the end this field looks like doughnut or toroid, the divergence of this field is most certainly not zero.

Interestingly enough, this goes along beautifully with what EDWARD LEEDSKALNIN told us quite some time ago when he was talking about "North pole individual magnets" and "South pole individual magnets". I suppose everyone knows about Ed, or at least about Coral Castle and Billy Idol's song "Sweet Sixteen"?

http://en.wikipedia.org/wiki/Magnetic_charge

- "Dirac showed that the existence of magnetic monopoles was consistent with Maxwell's equations only if electric charges are quantized, which is observed."

Aether and the speed of gravity

Speed of light is terminal velocity of EM fields. Therefore, just like free-falling object reaches terminal velocity due to air drag, so does the photon or any EM radiation have its terminal velocity due to resistance of Aether.

Speed of field potentials, the volume magnitude propagates much faster, possibly as longitudinal wave, which makes charges, as well as electric potentials and gravity, appear "rigid" and explains apparent instantaneous interaction over distance.

Aether and gravity. Helical or transverse propagation of EM fields and longitudinal propagation of their potentials would have different terminal velocity influenced by the density gradients or pressure differences of this fabric, which closely corresponds to gravitational potentials or inertial reference frames.

Vorticity and magnetism. Aether "fluid-dynamics" analogy is probably the most obvious in the photo below as we can see the right-hand rule just like with Lorentz equation, where the force acts inward, towards decreased density and is attractive just like with magnetic field of a moving charge. Biot-Savart law, magnetic field equation, can be used equally well in electromagnetics just as in aerodynamics.

http://en.wikipedia.org/wiki/Lorentz_force
http://en.wikipedia.org/wiki/Biot-savart_law

So, Lorentz was right after all

http://en.wikipedia.org/wiki/Hendrik_Lorentz

...Lorentz on his side continued to use the aether concept. In his lectures of around 1911 he pointed out that what "the theory of relativity has to say ... can be carried out independently of what one thinks of the aether and the time".

He commented that "whether there is an aether or not, electromagnetic FIELDS certainly exist, and so also does the energy of the electrical oscillations" so that, "if we do not like the name of "aether", we must use another word as a peg to hang all these things upon."

http://en.wikipedia.org/wiki/Albert_einstein

In the early 1920s, in a lecture which he was invited to give at Lorentz's university in Leiden, Einstein sought to reconcile the theory of relativity with his mentor's cherished concept of the aether. In this lecture Einstein stressed that, in general relativity, space is "endowed with physical quantities".

Shortly before his lecture in Leiden in 1920 he admitted in the paper: "Grundgedanken und Methoden der Relativitätstheorie in ihrer Entwicklung dargestellt": - Therefore I thought in 1905 that in physics one should not speak of the aether at all. This judgment was too radical though as we shall see with the next considerations about the general theory of relativity. It moreover remains, as before, allowed to assume a space-filling medium if one can refer to electromagnetic FIELDS.

http://en.wikipedia.org/wiki/Paul_dirac

The founder of quantum FIELD theory, Paul Dirac, stated in 1951 in an article in Nature, titled "Is there an Aether?" that "we are rather forced to have an aether".

And, why no one ever told you
how electrons actually attract?!?

http://en.wikipedia.org/wiki/Z-pinch

- "The Z-pinch is an application of the Lorentz force, in which a current-carrying conductor in a magnetic field experiences a force. One example of the Lorentz force is that, if two parallel wires are carrying current in the same direction, the wires will be pulled toward each other. The Z-pinch uses this effect: the entire plasma can be thought of as many current-carrying wires, all carrying current in the same direction, and they are all pulled toward each other by the Lorentz force, thus the plasma contracts."

initramfs UPDATE:
21.7mb - Live CD myOS-1_1_9.iso - 2008-03-12, arch = x86
This is initramfs build, so even tho its 10mb bigger it fits in less, only 64mb RAM disk. Extra 10mb are to feature WebKit based demo web browser from Trolltech's Qtopia Core, to compile Scitech SNAP/MGL projects just type: dmake
How to use?
Download iso, burn to CD, restart computer...

What computer?
Old build should work on almost all x86 based PCs, the oldest machine I've tried this on was AMD-K6, 266MHz, 128Mb, S3 Virge video card, with glgears running @ 10FPS... It will also run on some x86 based Apple Macintosh computers
New build has additional support for Mac specific hardware, uses initramfs and is further trimmed so it fits in only 64mb RAM;
PowerPC build for 'New World" Mac, G3 and up is in working stage but performs poorly compared to Mac OS 9 so there is no point of putting Linux there, or is there? [project abandoned, problems: graphic drivers, boot procedure, HD installation]
Why, what for?
It's about an idea - Linux can be simple, the whole development environment can be simple and free of additional configuration, installation or any other kind of hardware or software setup
Development system, platform independent, allowing for the whole application or game to be distributed on a Live CD or Live USB with complete OS included
Embedded Linux - mobile phones, PDAs, media players, public computers, ATMs, avionics, handheld consoles and other systems or terminals that need to run independently or safely without 'Hard Drive' or entirely from ROM chip
Base to build graphical windowing system on top of OpenGL
Personal mini-Linux on USB key-chain, rescue Linux, Secure information storage/processing mini-system
Simple, handy tool to teach, learn, use or just demonstrate C/OpenGL & Linux capabilities
"OpenGL without X" as well as Plug & Play side of it, is all thanks to GPL release of these fantastic drivers - SciTech. There you can find full source code and lot more OpenGL and other demos including game DOOM.

NDN windows in action - 'Welcome' splash screen
Minimalistic GNU/Linux system, stripped down of everything but core necessary files to compile and run OpenGL/C code. It has simplified directory structure and cleaned up internal cross referencing. Programs compiled in myOS will run on any Linux with or without X. (GPUs).
Copy of the OpenGL Red Book is included together with 45 examples from the book. Examples are organized by chapters, each in separate folder, ready to compile, run and play with. Source code is modified to use Scitech drivers and is very similar to GLUT version in the Red Book. This little collection is really all one needs to learn OpenGL. In fact the whole system, being very simple to use or analyze and understand, can be a tool to teach Linux basics and C/OpenGL programming.
With SciTech SNAP/MGL drivers (based on Mesa) it was possible to run OpenGL without X. Stripped down and modified GNU gcc compiler, mixed with diet libc includes and selected shared files seem to be able to compile all relevant libraries and produce stable and relatively small code. Beside Necromancer's windows manager and OpenGL developing tools this is pretty much your average 'Linux' thanks to BusyBox.
Size can be reduced even more, see this for inspiration:

FBO doesnt need depth renderbuffer as long as it have attached texture with depth component, this is surprisingly faster even with GL_FALSE read, write to color, so rendering to both depth and RGB(A) textures over FBO is faster than just rendering to depth texture, and since is faster to render all at once its cheap to combine other effects with shadow texture, like fog for light/shadows intensity fade-out, spotlight circles, projected transparent colored surfaces and so on...[need edit]

Artificial Neural Networks: Tic-Tac-Toe

2008-10-01T00:24:00.000-07:00

ANN Tic-Tac-Toe solved (plays a perfect game) with only a single layer perceptron network, mapping 255,168 combinations into only 81 bytes of connectivity logic. I did the 'network training' by "hand", as I could understood the method through which this ANN would output results, but I could not see the way to provide conditions which would produce the necessary state via whatever recursive or self-learning algorithm.

So, I hard-coded the Tic-Tac-Toe "brain" by hand, using plain trial-and-error, which turned out to be surprisingly easy, but I again could not quite put into words what, why and how did I do it, so I could not express the procedure with any algorithm, yet again. Nevertheless, the "brain" was there, and it lives! This particular implementation below does all the computation in parallel, which is quite "natural", or better to say 'only' mode of operation for natural neural networks, here executed on a video card, using OpenGL multi-texturing capabilities, so both logic and graphics of the game are computed by the GPU.

Glut -1st remake (Windows binary + Visual Studio source code)
http://www.mediafire.com/?ddmmswi1ngw
http://one.xthost.info/zelko/mElite-97-41.zip

Completely re-written AI, there are now battles going on in universe that are independent of player, pirates attacking trader convoys, police patrols attacking pirates or even complete war outbreaks.... this "Elite remake" should be in par with ArcElite (Archimedes Elite), well at least that was my goal... but there is more, hard-coded 7 extra missions and added many other features that appeared in Elite remakes and some completely new stuff...

MISSION 1. - Bad dream
After launch you notice unusually large number of viper patrols and other space ships around the station and they soon start shooting at each other... and you. This is a good time to warm up and get some score/rating. (Go after bad guys for extra points)

MISSION 2. - Asteroid shower
In 'real life' on Lave Space Station things are not much better. Large number of Asteroids is heading for the planet. Opportunity to earn some cash here. (When reinforcement arrive be quick or they'll shoot off your money)

MISSION 3. - Zurid Pino and Cloaking Device
Nasty pirate is menacing peaceful trading region and it has Cloaking Device. Later on you are told that pirate might be infamous Zurid Pino and that you better get E.C.M. There is also a reward if he is captured alive. Once you meet him you will find out that ship can not be missile targeted and scanner has problem tracking it. (For bonus reward and cash don't destroy the ship until Pino launches Escape Pod. When he bails quickly destroy the Cougar and only then catch up and scoop Pino's capsule. After that hurry up and scoop the cargo and other debris before it drifts away. Before you scoop anything check if you have enough space in your Cargo Hold, if not jettison less valuable items and shoot them for points)

MISSION 4. - Supernova
After arriving at Razaar system your on-board computer displays a message that fuel leak is detected. That actually is the least of your troubles as soon you will find out that that Razaar's sun is going "Nova". It's complete chaos and the station is out of Hyperspace fuel but at least they will supply you with a new ship. The new ship comes with important passengers and a new mission, but first you must survive Supernova. (Clear off all the traffic running away from the planet, then once you are far away to engage Warp Jump engine be sure to have planet and sun in you REAR View because you'll need to be far, far away to survive Supernova blast... look for new planet description if mission completed successfully then scoop either of two suns for fuel)

MISSION 5. - Asteroids on Qube system
Same as 2nd mission, but this time there are other pilots around from the start and you will have to be quick to earn your money. (You may notice a new gadget in your ship, a gift from Razaar refugees to help you keep track of your missile target)

MISSION 6. - Constrictor
Her Majesty's Space Navy makes note of you and gives you the mission to catch pirates that have stolen top-secret experimental naval ship prototype. This is a classic unchanged mission from the original BBC Elite. (For bonus reward capture the crew alive. Since police chased them away of station before they re-fueled you will find them near the sun trying to scoop)

MISSION 7. - Genesis Capsules
"...We need to find some other way of releasing Ecology Seed and dispersing it in the planet's atmosphere. Simultaneous activation at low altitude is the best we can try now without proper equipment. Capsules are being loaded in your ship in special food containers. ---MESSAGE ENDS." (At low altitude jettison all the containers and activate Energy Bomb... look for new planet description if mission completed successfully)

MISSION 8. - Thargoid documents
As in original Elite - "I have obtained the defence plans for their Hive Worlds. The beetles know we've got something but not what. If I transmit the plans to our base on Birera they'll intercept the transmission. I need a ship to make the run. You're elected. The plans are unipulse coded within this transmission. You will be paid. Good luck Commander. ---MESSAGE ENDS."

MISSION 9. - The Battle For Birera (Thargoid Invasion)
"...The Hive World plans have been retrieved from your on-board computer and decoded successfully. The future of the whole Galaxy may now be in our hands. Birera Station must be defended at all cost. Die hard Commander. ---MESSAGE ENDS."

Have Fun!
