I'm working on resuming the FOT????
by Jim Muth 26 Feb '16

26 Feb '16

Fractal fans: I'm still here and ready to resume my fractal adventures, but my 21-year-old DOS machine dedicated to Fractint is at the end of the road. I have two other working machines, both running Windows-XP, which probably for video incompatibility reasons will not run the DOS version of Fractint. Is there a version of Fractint that will run under XP and operate similar to the DOS version? If there is, I would appreciate the internet address. I'm sorry to hear about Paul Lee. Jim M.

Fractal of the ? -- test
by Jim Muth 24 Feb '16

Fractal enthusiasts: This is a test to see if I am still subscribed to the list. I might be resurrecting the FOTD as the FOT? in the near future. Glad to see the list has not died in my absence. Jim M.

David, > Setting up mirrors would be something, if one's hosting > package has the space & bandwidth. Good idea, but, hopefully, a mirror site won't be necessary: I spoke with Paul's close friend John Starr, and he said that it was Paul's explicit wish to have his Fractal servers kept online. John is an executor of Paul's estate, but a minor legal holdup is slowing his work down. - Hal Lane ######################## # hallane(a)earthlink.net ######################## -----Original Message----- From: Fractint [mailto:fractint-bounces@mailman.xmission.com] On Behalf Of David Jones Sent: Sunday, February 21, 2016 5:07 PM To: Fractint and General Fractals Discussion <fractint(a)mailman.xmission.com> Subject: Re: [Fractint] <Ton> Thank you for the information about Paul N.

Interconnected
by Mike Frazier 23 Feb '16

23 Feb '16

This fractal mixes two copies of z * z * cos(z) * sin(z) at slightly different locations. I noticed that areas with spiral features also had a lot more arms so I searched the area until I found this fractal. It is very intricate and everything seems to be interconnected. Here is a link to an image: http://dl.dropboxusercontent.com/u/33642054/image/pr_3cossin-3cossin_H_1200… The FractInt compatible PAR file for the image is: Interconnected { ; Exported from Fracton. reset=2004 type=formula formulafile=fracton.frm formulaname=F_20160222_1054 passes=1 float=y center-mag=-0.7777678014027933/2.214634821764375e-\ 06/240717564052.7675/1/0/0 params=1/1/0/0/-1/0/1/0/0/0 maxiter=2000 inside=0 periodicity=6 colors=000C10O40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O\ 40C10000C10O40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40\ C10000C10O40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C1\ 0000C10O40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C100\ 00C10O40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000\ C10O40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C1\ 0O40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O\ 40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40\ ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40ZA\ 0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40ZA0h\ I0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40ZA0hI0\ oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40ZA0hI0oS\ 0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40ZA0hI0oS0u\ a0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40ZA0hI0oS0ua0\ ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40ZA0hI0oS0ua0ym\ 0zy0ym0ua0oS0hI0ZA0O40C10 } frm:F_20160222_1054 { ; Similar to the parallel resistance formula a=real(p1),b=real(p2),d=imag(p1),f=imag(p2), z=0,c1=pixel-p3,c2=pixel-p4: cs=z*cos(z)*sin(z), z=1/(1/(cs+c1)+1/(cs+c2)), |z|<100 } -- Mike Frazier www.fracton.org

Shortarm Castle
by Mike Frazier 22 Feb '16

22 Feb '16

This fractal mixes two copies of z * z * cos(z) * sin(z) at slightly different locations. The area around the fractal has lots of short arms interconnecting the features. If you zoom in more on the main feature on the right it looks like a castle with six towers. The zoomed in images need arbitrary precision math but the first image works fine with double precison. Here is a link to an image: http://dl.dropboxusercontent.com/u/33642054/image/pr_3cossin-3cossin_BC_120… A deep zoom into the feature on the left using arbitrary precision math and a different color palette: http://dl.dropboxusercontent.com/u/33642054/image/pr_3cossin-3cossin_CD_640… A zoom into the castle feature on the right using arbitrary precision math and a different color palette: http://dl.dropboxusercontent.com/u/33642054/image/pr_3cossin-3cossin_DD_640… The FractInt compatible PAR file for the first image is: Shortarm_Castle { ; Exported from Fracton. reset=2004 type=formula formulafile=fracton.frm formulaname=F_20160221_1004 passes=1 float=y center-mag=-0.6417820664871355/0/9172173044.248877\ /1/0/0 params=1/1/0/0/-1/0/1/0/0/0 maxiter=2000 inside=0 periodicity=6 colors=vQ1h_FViSIsdGnREiDCe0Ec8GaGI_OKYW000MWcOUkQ\ SrTUrWWrZYra_rdargcridrjYokSlkMjlGglAej9Zh8Sf8Ld7E\ c77_A8WD8SG9PJ9RELSAXT5hU1tha9VaLIaX8GHEURBNLIuBGn\ CEgDD`EBUF9NG7ct8S_I53G86EA9CCBAEEGkOCWKSk8NcAIWCD\ OE80P84N87L8AJ8DHhWEaTFWQFQOFKLGEIGdNYOJPaz3NbAPVV\ KRRGNNCJJ1CO5EKLcNJ`MHYLGVKESJCPIBMH9JGqtjknfeib_d\ ZV_VPVRJQNDLJ5_n6Wh6Tb7QX7MR8JL1Cr3Dj4Eb6FV7GNxfdm\ `_bWVTQQILLQCcLDYHESCFMVHHRGGOGGLGGHGGEGGBGG9je8VT\ ipUXcPKSKcRe_PaWOZSMWOLTKKPGIMCHJxa4pY6hV8aSAUPBNM\ DFJFHZBJ44G77E99CCCAEEhMBWKDKIFhnVahSWbQQXNKRLELIh\ G7cG9ZGAVGBQGCLGDHGECGFiIkaHdUHZNGSFGMhJkZIcQHWHGO\ lpmfkhafdXb`SYXNTSIPODKKyiRBmhAd`9XU8ONM_9JWBHTCFQ\ DCMEAJFlf6ea8ZYASTBLPDEKFhW60cw4Savl3XWAulFdaGhlEh\ q7c3vZ9nUEfQJZLOSHTKCYC8b5E_6KX7QU7WR8aO8gL9mJ9lIC\ lIFlIHlHKlHMlHPlHRdKPXNNQQLITJBWIJUNQTSXRXcQajOfqN\ kxMosKhoIbkGWgEQcCJ_BDkJ7 } frm:F_20160221_1004 { ; Similar to the parallel resistance formula a=real(p1),b=real(p2),d=imag(p1),f=imag(p2), z=0,c1=pixel-p3,c2=pixel-p4: cs=z*z*cos(z)*sin(z), z=1/(1/(cs+c1)+1/(cs+c2)), |z|<100 } -- Mike Frazier www.fracton.org

Paul N. Lee and other things
by Barry Smith 22 Feb '16

22 Feb '16

I would like to join Hal Lane and others in mourning the passing of Paul N. Lee. I was very saddened to hear of Paul's death, although I never met him in person. As others have said, he was a frequent and generous contributor to this list, sharing his knowledge and understanding of fractals. He also maintained a web site and a valuable archive, which others are now trying to keep going. But this is not all. He was personally very kind and generous of his time. A couple of years ago, I had some problems when my messages to various people, including him, were bounced. He made many helpful suggestions to me away from the list. In the end I discovered that the problem was caused by my ISP being taken over by a larger company. Its incompetence resulted in the Grapevine domain name being blacklisted by several mail servers including AT&T. Some people may not know that Paul had a long and quite ghastly time with cancer and had countless surgical and medical interventions. Despite this, he kept posting. His story resonated with me as a cancer survivor. I was fortunate not only to have a good oncologist and a good haematologist, and to live in a country with a rather better health funding system than the US, but there was a genetically modified drug capable of treating my form of cancer, which, followed by an autologous stem cell transplant and a long convalescence, more than sixteen years ago, proved quite effective. Others are less lucky. I am also delighted that the Fractint list may not be moribund. Since Albrecht's latest dummy-spit, the list has been very quiet. It was great to hear that Jim Muth may resume posting fractals at least occasionally. For many of us Jim's FOTD epitomises what the list is about. Thank you also to Mike Frazier for keeping things going. Barry Smith, long time lurker from Australia.

Capturing Paiul N Lee's sites
by Timothy Wegner 22 Feb '16

22 Feb '16

I am replying to an earlier message so the background of Paul N. Lee's health as of last December and his web sites would show up in the quoted text. As of right now his sites are up. A lot of what follows is off topic, but a little discussion about preserving his sites probably appropriate give that a long time list member has died. Paul's web sites appear to be mainly (if not entirely) static html which is extremely easy and inexpensive to host. For example, I have a headless 486-class server running a miniature version of Linux that I am using at home mainly as a learning platform. Such a system can easily host a large amount static html. Web hosting is technically against Comcast's terms of service, but in practice they don't seem to mind as long as the customer is not hosting a high traffic site. This tiny 486 box consumes about 5 watts, so is close to "free" to operate. Another approach is to use one of the cloud computing services provided by any number of folks such as Google, Amazon, and other less familiar names like Digitalocean and Dreamhost. The smallest versions of these, typically with 1 gb ram, are more than suitable for a static website, and cost about $10/month. For example, I am experimenting with Google and Dreamhost. These links will not last, but see these ports of the static fractint.net site: gc.fractint.org, and dc.fractint.org ("gc" for Google Cloud and "dc" for DreamCompute). Google has a 60 day free trial. Amazon has a one year (!!) free trial. The downside of these services is that they are unmanaged. That is you install a stock Linux (or whatever) and are on your own to set it up and manage it This is in contrast to fractint.net, which is (currently) hosted on a managed Virtual Private Server (VPS) ($15/month for 1GB ram instance). In otherwords, Dreamhost keeps the software updated and has configured the web server. I initially found the prospect of hosting on an unmanaged server daunting because I just didn't know enough, but I am learning fast. I do this partly to keep my old brain engaged with technical challenges for my own health. Actually, plain old fashioned shared hosting would probably suffice for Paul's content, this costs as little as $4/month, and is managed. This thought occurred to me after I wrote the long previous paragraph. Anyone who already has hosting could make a sub-domain, and add the static content. There are tools (see https://www.httrack.com/) that can capture sites. Of course this would be easier if Paul has given someone access to his sites so the html could be obtained directly. One issue is that some of Paul's sites I would personally be the most interested in capturing are to a greater or lesser degree in need of maintenance, mainly cleaning up of dead links. Among other things, Paul captured Noel Giffin's spanky site, which has many dead links. I am not sure how deep I want to get into editing the sites, but I am interested in content that is more fractint-related. If anyone has anything to offer on this, maybe for a little while we should declare how to capture some or all of Paul's fractal sites on topic. I would be interested in knowing what of Paul's content folks would like to see saved. Or if someone else is just going ahead and doing this, I would like to know that too. PS Just saw Harold Lane's note about John Starr, so as Harold said, maybe this is moot. Tim See quoted material below.
