Hear, hear Tim. Cheers and thank you. Nicely put! John W. On 12 March 2015 at 20:08, Timothy Wegner <tim@tswegner.net> wrote:
Albrecht,
I choose my words carefully and always answer you respectfully. The words you are attributing to me are not respectful. Of course I cannot control what you think when you read my emails, that is your responsibility, but best not to confuse those thoughts with my words. I don't believe I ever told you to "back off".
The actual situation is that Fractint was built with thousands upon thousands of hours of volunteer time, a large number of them by Jonathan and myself, but also from hours from many others. You have benefited from this contribution, and I hope you have some appreciation. Fractint is built with early 1990's technology that has severe limitations. Endless optimizations have squeezed a huge range of zooming into finite resources and allowed complex parser formulas to be utilized despite old technology. Apparently Fractint supported your multi-fractal project for the last 12 years. I am not exactly sure why suddenly your project must stop because of some unintended consequences of Jonathan's last patch, his first in something like four years. But of course whether you continue your project or not is your decision, and yours only.
In the entire time I have worked on Fractint the developers have never put any pressure on each other. We were completely clear that the effort was voluntary and done with discretionary time by people who had many obligations. I'm not going to start now by putting any pressure on Jonathan. As if that would matter. Jonathan is undoubtedly interested in the technical problem posed by his patch and the demands of your fractals. I'm guessing he will look at it. Jonathan has an extraordinarily demanding day job working at a nuclear power plant. His discretionary time is limited. So there is no telling when or if he will get to it, or if he does get to it, if he will make any changes that will relieve the constraints your multifractal project is experiencing.
We don't know if the problem we are seeing is caused by Jonathon's patch or if an existing memory violation was changed from being innocuous to fatal. Memory problems are among the most difficult to debug.
My suggestion to you is not to "back off", but to see if your researches can continue less close to the edge of Fractint's limitations. Maybe they can't, I don't know. My uninformed guess is that if you put the same effort into optimizing your parser formulas that we put in the fractint coding, you could happily continue. But I might be dead wrong, and I really don't know quite what you are attempting or what your vision is. SO "back off" would seem to be inappropriate advice coming from me.
If you really want help from Jonathan, do some experiments and find out exactly what triggers the error. Exploit the fact that he is interested. Give him some information, but respect the fact that his time is limited. But asking me to somehow get Jonathan to do what he either can't or won't is a losing proposition. I have zero authority over Jonathan nor do I want any. I last changed fractint code maybe 15 years ago. Even when I was active my skill set was different than Jonathan's. Right now I am not the answer to your Fractint problems.
You have a number of fans in the forum, and have injected some life after Jim Muth's changing interests reduced his participation. Jim has single-handedly kept the forums alive for a very long time. You have made things very lively recently, and a number of folks, including me, appreciate that. That said, all things come to end sometime. When the activity in the Fractint forums ebbs to a trickle, nothing tragic will have happened. The universe will go merrily on.
I can hardly believe that there is still a fan base for Fractint after all these years. One of those technological mysteries. Every day interesting material is posted is a bonus.
I wish you well. I hope you keep posting, but if you decide not to, your decision will be respected by me.
Tim

This is what I´ve been told to do on my request to fix the lack of memory crashes caused by the latest fractint update. /"You just need to back off on the demands of your fractals// //so they are not at the edge of Fractint's capabilities."/ This means the end of my multifractal project after 12 years, nothing less. So the last Mohawk has to go. Albrecht
