FOTD 21-04-11 (A Fascinating Mess [3])
by Jim Muth 21 Apr '11

21 Apr '11

FOTD -- April 21, 2011 (Rating 3) Fractal visionaries and enthusiasts: In today's image I tried something I have rarely if ever tried before. I created a fractal with the inside set to 'startrail'. I'm not sure what to make of the result. After a few minutes pondering, and with nothing better in mind, I named it "A Fasci- nating Mess" The formula is the Mystic2, which draws nothing but empty circles that must be brought to life by an active inside fill. In today's image I chose the image created by the 'startrail' fill, though the other active inside fills also draw interesting images well worth further investigation. With so many hairline tendrils, the image looks best when rendered at the highest resolution available. At the default 640x480 the tendrils break up into little more than scattered dots. The scene is filled with interesting nooks to zoom into and explore. In a few days I might find something down in there worth the exalted status of FOTD, though for all I know, it could be a dead end. Don't be put off by the rating of a humble 3. It is equal to a 5 on the old scale, and the calculation time of only 10 seconds means that no effort will have been wasted if the image is disappointing. The finished image is available on the FOTD web site at: <http://www.crosscanpuzzles.com/Archives.html> a high-definition version is available at: <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> The original FOTD web site may be found at: <http://www.Nahee.com/FOTD/> A cloudy morning here at Fractal Central gave way to a bright sunny afternoon, with a pleasant temperature of 73F 23C. The fractal cats approved of the outside conditions but did not approve of a stray tomcat who sprayed their front door. They responded with thrashing tails. The humans had a reasonably peaceful day, though no day here at FC is ever totally peaceful. The next FOTD will be posted in 24 hours. Until then, take care, and sometimes miracles happen when least expected.

We just received an Xfractint patch for the Mac from Marcus Pallinger Very few changes are needed. We'll have to see how it works. Tim

. Stop moaning you two guys. I'm not too far behind either. So what. Time marches on. Chronologically over 50, body is around 35-40 (active lifestyle benefit) Mind is perpetually 14-18; as long as I can slip an Iron Maiden CD in, crank it up all the way, and rock into it I figure I'm still ok. Constantly driving 15 over the limit w/o getting nabbed helps too. Age is in the mind and spirit. Many people past 50 can't do much technical or mathematic, but you (and I and others) are immersed in the 4th and most recent mathematical and philosophical breakthru in history (the others being calculus, relativity and quantum mechanix). Fractals are a graphical depiction of a very broad and ever expanding field which used to be (sometimes still is) called Chaos Theory, but now referred to as "complex systems" or "non-linear dynamics". It will only get bigger in the years to come. So stay on it! I intend to. BTW, for those interested in the broader aspects of this, and have some coding skills (BASIC or PASCAL), I recommend a book called "Chaos Cookbook". It is somewhat hard to get now, but Amazon has it by 3rd party sellers. Get it while you can! Stay Amazed JoTz .

Recently I showed an image of the FOTD for April 15th rendered by Fracton. You can read Mike Frazer's comments about this here: http://www.fracton.org/fotdtesting.html Here is a rendering by Fracton of today's FOTD: http://linuxenvy.com/bprentice/Fracton/Fractal%20Evaporation.png As you can see it shows features similar to those of the earlier image (Something From Nothing). Do you have any comments on this matter Jim Muth? Does any other reader of this list use Fracton? Brian Prentice

General Discussion
by Albrecht Niekamp 20 Apr '11

20 Apr '11

HI, thanks, Jim good to know, I´m not alone with this. qte: IMO, "What is the meaning of life?" is the greatest unanswered question facing mankind. And neither religion nor science has anything near an answer that is both believable and satisfying. With this kind of despairing mindset prevailing, no wonder the world is in such turmoil and so many are seeking relief in drugs and trivial distractions such as the plague of violent games now infesting our culture. unqte These are good words. Violence in life and in media and suicide by atomic disasters are symptoms of an apokalyptic end time scenario. I have my own theory about religion and human behaviour, only vagely connected to fractals. Not sure if it´s ok to discuss it here. Tell me. qte: As to how I maintain my interest in fractals, I do nothing. I have never lost the original fascination I felt when I saw the Scientific American article about the Mandelbrot set back in 1984. I have always loved math, mysteries and exploration. What better place to find these things than in the infinitely infinite world of fractals. unqte I must admit that after seven years of abscence from fractals the virus again has caught me. In addition is creativity the most healthy thing you can do for yourself. I think you´ll agree. So I´ll go on. Sincerely, Albrecht

Anyone have any info re diffs in the DOS environment between WinXP & Win98?
by Hal Lane 20 Apr '11

20 Apr '11

I believe that there may be some significant differences in the DOS environment that DOS programs "see" between WinXP and Win98 (where you could actually boot into the Win98 version of DOS.) I've had a situation with fractals that *would* calculate successfully at 640x480 in Disk Video Mode, but become corrupted when two copies of FRACTINT.EXE were running (calculating different fractals) in two 32-bit WinXP DOS CMD windows at the same time. I seem to remember that I could have several fractals being calculated simultaneously in DOS fractint in separate DOS windows (on the Win98 Windows desktop) and they would all calculate correctly. When doing the same thing in WinXP I find that one fractal will corrupt another being calculated at the same time -- almost as if the two copies of Fractint in the two 32-bit WinXP DOS CMD windows were sharing some of the same memory. Does anyone have any comments or info about this? - Hal Lane ######################### # hallane(a)earthlink.net # #########################

Hal Lane - A Couple of questions
by Albrecht Niekamp 20 Apr '11

20 Apr '11

Repeating my message as possibly only Hal could see it. Hal, 1st question: Yes, it is 2nd question: Yes, in DOS mode which I have on another machine.I have to leave the "Newdos Commander" to start calculating. With shorter versions it is not necessary. But possibly you´re right and the input section is not the problem. Anyway I´m getting that "insufficient memory" error if I dont close the DOS commander so it´s certain that the limits have been reached.

FOTD 20-04-11 (Fractal Evaporation [7])
by Jim Muth 20 Apr '11

20 Apr '11

FOTD -- April 20, 2011 (Rating 7) Fractal visionaries and enthusiasts: NEW FORMULA ALERT! Today's image was created by a new formula, which I tweaked up Tuesday. The formula appears at the end of this message. Delete the initial <frm:> and copy it into your favorite formula file. The formula is the same as the original MandNewt06 except for the new p4 parameter, which adds a variable bailout capabil- ity. Increasing the value of p4 evaporates the images; decreas- ing the value solidifies them. (The exponent is negative and works in reverse.) The image was calculated with a bailout value of 2*(10^-29), a value at which the background has broken up into dots but not yet totally evaporated. Lowering the negative exponent actually increases the parameter value and causes the background dots to become more numerous. Increasing the exponent has the opposite effect. The name "Fractal Evaporation" describes the action. The rating of a 7 would be an 8 on the old scale. I actually think the image is pretty attractive. The calculation work may be avoided by viewing the finished image on the official but unfinished FOTD web site at: <http://www.crosscanpuzzles.com/Archives.html> The image may be seen in hi-def at: <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> The original FOTD web site is still to be found at: <http://www.Nahee.com/FOTD/> but it has not been updated for several months. Weather misery prevailed here at Fractal Central on Tuesday, as a steady rain fell all day and the temperature hardly budged from a chilly 48F +9C. The fractal cats spent the day doing things other than watching the rain. The day of the humans was near normal. The next FOTD will be posted in 24 hours. Until then, take care, and keep checking the new FOTD web site. You never know when some outrageous stuff might be posted there.
