Reflections on My Tech Career – Part 1
I’ve been lucky enough to have had a successful career as a software developer. Spanning six companies and thirty-seven years I’ve had the opportunity to work on Elastic Reality, Xbox, Windows, Steam, Internet Explorer, dozens of games, and Chrome, and … Continue reading
Making a 4K Fractal Movie with Fractal eXtreme
Four years ago I created a HD fractal movie because I wanted to see how quickly Fractal eXtreme could calculate the same movie that Orson Wang had posted to youtube. My version of his movie was antialiased and 720p and … Continue reading
Out of Order Benefits
A few months ago I wrote about some experiments to see how fast modern CPUs are at doing high-precision math such as is used in cryptography and high-precision fractal calculations. I recently read an article that claimed that out-of-order processors … Continue reading
Fractal eXtreme, now cheaper
As an experiment Fractal eXtreme is now just $9.95. The latest version has a few bug fixes and performance improvements, is a free update to all existing users, and is cheap like borscht.
Fractal and Crypto Performance
There was some recent interest in what type of computer would run Fractal eXtreme’s deep zoom calculations fastest (and cheapest) so I wrote a benchmarking tool that isolates the inner calculations for more accurate measurements and arranged to have it … Continue reading
Fractal eXtreme New Version–Better Zoom Movies
While working on the Really Deep Fractal Zoom Movie – Much Faster project (240 times faster!) several updates were made to Fractal eXtreme in order to improve the creating of zoom movies. These improvements are now available as part of … Continue reading

Really Deep Fractal Zoom Movie – Much Faster
A few weeks ago while browsing YouTube for Fractal movies I came across a video that claimed to be (as of its post date of January 26, 2010) the deepest zoom movie on YouTube. The video was of an interesting … Continue reading

Faster Fractals Again
I was calculating a long fractal zoom movie with Fractal eXtreme when I noticed that one of the phases seemed to be taking too long on my four-core eight-thread processor. A bit of investigation showed that this phase was effectively … Continue reading

Then and Now–Performance Improvements
In a recent post I made an offhand comment that in one fractal calculation scenario my new laptop is about 37,500 times faster than my old Amiga 1000. I suspected that in other fractal calculation scenarios the improvement is much … Continue reading

Faster Fractals Through Better Scheduling
Performance improvements can come from many directions including better algorithms or micro-optimized inner loops. In this case I got a worthwhile speedup by working better with the Windows thread scheduler.
