Creating an Icon Cache file

     The screen shot above shows the debugging interface for code that creates a custom Icon Cache file for an application. After spending weeks grappling with palettes (not a trivial matter), and Icons being returned with indeterminate bit counts by API functions, and complications surrounding different screen resolutions, and the sometimes strange behavior of the save and load functions associated with ImageLists and bitmaps, I finally hit upon a plan to create a custom Icon file that avoids all these problems and meets my objectives. Having a cache of icons required by a certain program is much faster than going through the Windows registry and then hopping all over a hard drive looking for icons.
      This demo illustrates one way to create an icon cache for a program. The icon cache file it creates has the following format:
4 bytes - number icons cached in the file
4 bytes - width of icons
4 bytes - height of icons
followed by the raw pixel data for the XOR color bitmap in pf24bit format
followed by the raw pixel data for the And mask in pf1bit format
followed immediately by another XOR map, another AND map etc

      By saving the pixel data for the color XOR bitmap in 24 bit format the code avoids the problems of different screen display settings and problems with API routines returning bitmaps from icons of indeterminate color depth and also avoids problems of icon palettes (returned as zero) and strange colored icons that can result. The API icon routines will accept a 24 bit (XOR) bitmap for the icon creation routine, and by using 24 bits the need for palette data is eliminated, and by fixing the pixel data size at 24 bits the need to be concerned about different screen resolutions, default values and other complications is eliminated (at the price of a couple of bytes per pixel to store the Icon data). When the cache is created with a smaller bit count I encountered problems with uncolored icons, greyed icons, palette complications, icons covered with colored films at 16 bit resolution, changing bit counts that take place when 16 bit bitmaps are loaded and saved, and so finally I opted for a true color bitmap for the raw bitmap pixel data for the icon cache and after struggling with issues for a couple of weeks the code just wrote itself in an hour or two.

      The open file button is set to open a dialogue pointing to an intial directory of 'c:\windows\system' and the file filter is set to Shell32.dll for convenience. Hit the Get Icon button a number of times to load some icons from the shell into the image list, then hit the save button to save the icons as a cache file and then reload the cache file and recreate the icons by hitting the load button. You can then surf through the icons recreated from the cache stored on the image list by hitting the view button to cycle through icons on the list.

The code for the project can be downloaded as a Delphi 3 / Delphi 5 project in a zip file ... icon_cache.zip 17 KB or you can view the text file here ... icon_cache.txt

Principles of Evolution: A Study in the Evolution of Bedbugs

A couple of years ago my bedroom was invaded by bedbugs. There were two variant genetic lines. One type of bedbug was an enlongated, thin, tubular insect, and the second genetic line was a flat, perfectly circular insect. The result of the cross breeding of these two genetically distinct variants was the production of a bedbug with charcteristics of both, an enlongated, flat bedbug with a central bulge (such that the shape of the bedbug was somewhere between 'long' and 'circular'). The long skinny bedbugs were such strange and unfamiliar looking insects that at first I did not recognize them as being bedbugs, and considered them to be a seperate species of insect. However, as the photographs of bedbugs above indicate, enlongated and skinny bedbugs are not uncommon, and the photographs also show the variants that are produced by genetic combinations that result in an insect somewhere in between 'circular' and 'enlongated'.

Therefore it is my hypothesis that evolution occurs by means of the transfer of dominate genes, with the production of such dominant genes being the product of 'biological algorithms', a genetic software program that brings physical characteristics into harmony with behavior, such that when behavior changes, and a conflict then exists, this acts as a trigger and causes the release of dominant genes. The result is rapid evolution of species. The bedbug is a relatively new insect, not the product of millions of years of evolution but rather an insect that is evolving in real time. The newly emerging dominant form of the insect is the flat, round ciruclar insect, well adapted to living in human bedrooms (it is flat, rather than tubular, thus allowing it to hide in the smallest cracks, living a stealthy lifestyle, and it is round, which gives the insect a maximum storage capacity such that it must endanger itself only a few times a month by emerging to feed.

Other examples of rapid evolution include the development of long legs in an invasive species of toad in Australia. As the toads move into the mountainous regions of Australia, and their behvaior changes, making them 'climbing toads', over the course of just a couple of decades the toads in the highlands have grown long legs specially adapted to climbing. It is worth noting here that the toads are poisonous, and are a successful invasive species because they have no natural predators in Australia, and so it would not be the case that the toads with long legs were 'the fittest survivors', because all the toads are survivors, and therefore predation does not explain the rapid emergence and spread of such well adapted, long legged toads. Once again we see evidence for the existence of biological algorithms and the rapid spread of dominant genes through a population, which once introduced proceed to overwhelm the older genes which are being replaced (making toad long legged and a bed bug round and flat).

A Theological Experiment

My interest in pursuing the Unified Field Theory is spurred on by my need to discover the theoretical explanation of a new form of propulsion (as explained on this page: Why the Unified Field Theory?). The experiment involving the bedbugs came out of nowhere.

I also believe that it is possible to justify theological propositions using experimental methods. If a thing is an objective truth then it can be verified and proven true by means of experimentation. Such a theological proposition is of more value than a ‘divine revelation’, since such revelations depend upon nothing more than establishing authority figures which requires the creation of artificial hierarchies, for the only reason why I might be encouraged to believe an authority figure who orders me to believe unsubstantiated opinions is if I could somehow be convinced that this authority possessed a mind that was somehow superior to mine, and thus was fit to express opinions as though opinions were unquestionable facts and thus worthy of being elevated to the status of absolute dogma.

There is a self evident human inequality which is visibly apparent. Some people are ‘beautiful’ and thus are the true elite on this planet, and some people are not. It is this sexual inequality and the degeneration that follows upon beauty that is the true driving force behind all the evil that happens on earth. The need for ruthless oppression and the pursuit of wealth and the consequent creation of suffering and poverty which must follow upon this practice is for the purpose of creating an artificial alpha elite.

The true elites are the young and the beautiful. The artificial elite are the rich and the wealthy. The elite aging rich artificial alpha male has no good looks, for he is physically degenerate, but he will be found escorting beauty because he has a beautiful wallet. If he loses his wallet he will be found at home with all the other unattractive aged beta males sitting in a rocking chair watching reruns of Bonanza. No money, no sex. It is for this reason that the alpha males are found to be so ruthless and so violent in pursuit of their goal. The alpha male has fallen. The beta male has arisen and now the whole planet is full of ruinous destruction for it.

We see in religion a confused and contradictory reaction to this reality. On the one hand religion preaches a sexless heaven where castration and the clitorectomy create ‘pure spirits’. Muslims throw women under sacks. On the other hand religion supports hierarchy and is the prop of the elite alpha male. It is for this reason that religion is incoherent when it comes to speaking about sex.

Now we see this same principle at work in all of nature. Guppies dance and show off their colorful tails and the guppy who dances with the most colorful tail is the sexually successful guppy. Therefore it is the doctrine of the ruthless oppressor which teaches that the solution to human sexual violence is to be found in castration and the creation of pure ghosts. This would be equivalent to damning an aardvark for having the ‘sinful aardvark nature’ or prosecuting an anteater for the high crime of ‘ant genocide’.

Therefore it was my theological hypothesis that the correct solution to this problem is to give every guppy a beautiful colorful tail. I compare this solution to the classic religious solution which is to cut off every tail since having a tail is ‘sinful’. If having a tail is sinful then God must be sinful for no human being has any choice in deciding whether or not they would be born with a colorful tail, or whether they would not.

When I was young I was a beautiful guppy with a lovely tail. So everyone seemed to think. I am older now. My nose became very badly sunburned and destroyed. It seemed good to me to test my hypothesis by using these ‘biological algorithms’ to correct this problem. I healed half my nose as you can see by the line separating the still very dark patch on the side in the photograph below.

I documented my experiment on these pages. one two t hree four fi ve six

I have confirmed to my own satisfaction that my theological proposition is correct and that religious dogma is erroneous, being based as it was upon nothing more than ‘divine revelation’ which is just a form of opinionated speculation. For the time being I am not continuing this experiment, for I must wait until the weather on this planet improves, and the dark clouds of ruthless oppression break letting a little sun shine come through so that I can show the world the truth about God, by showing people how God goes about giving an old guppy back his beautiful colorful tail.

Until then I will have to sit on the sidelines, while all my scientific breakthroughs are deliberately ignored, while I wonder to myself what ever in the world could be wrong with the human race, because what this all will prove at the end of it all is that there definitely was something wrong with the people on this planet.
