The common Mandelbrot set is really a 2-dimensional slice of a 4-dimensional object identified by both the combination of the complex numbers Z0 and C in the canonical Zn+1 = Zn^2 + C. The mandelbrot set lives in the plane where Z0 = 0 + 0i, while the Julia sets live on infinitely-many-squared orthogonal planes in the remaining two dimensions, each one intersecting Mandelbrot's plane in a single point of complex coordinates C.
Hey, I've just installed this new version and already managed to crash it five or six times viewing very popular pages. Besides, the Java plugin installation still doesn't work for me. I've reported all these incidents with the talkback agent, so perhaps next time it will be better. //BernardoInnocenti
Even with old Amiga floppy disks there were ways to retrieve some bits of data after a full format or overwrite. Blocks are separated by small gaps and tracks don't take up the whole 360 degrees of magnetic surface. On the Amiga, the disk controller was optimized for speed so it would not bother waiting for the index signal before starting to rewrite a track. Each time you rewrote a track, it would occupy a different section of the circle, leaving some old data where a clever guy could still retrieve it.
Today's hard drives are much more sophisticated than this, so they sure leave many more chances open to retrieve old data in original ways.

It's already 5 years that OOP design has lost its hype.
Get some recent books on C++ or general design
topics and you'll see that the focus has already moved away from classic OOP. Today's hype is mostly for generic programming (which I second) and design patterns (which I don't like that much). There are *lots* of books suggesting *NOT* to abuse inheritance and other OOP techniques of the past. Yes, even simple
inheritance is bad if it leads to a deep hierarchy.

Yeah, like in this case. Please apologize for your stupidity
I see this bug regularly on my Thinkpad X220 laptop running Ubuntu 12.04. Is there a tracking bug on Launchpad or in the Freedesktop bugzilla?
Free Software Foundation website published a detailed chronology of the incident.
Not to rain on your parade ... but the article's mandelbrot looks a hell of a lot more detailed.
We're comparing a power 8 version of the generlized Mandelbrot formula (Zn+1=Zn^k + C, with k=8) against a power-2 quaternion Julia.
In the epilogue, the author admits that there's less variety in the Mandelbulb-8 than even in the classic Mandelbrot.

Visualizing this hyperspace monster was made easy by POV-Ray. It took my computer two week of computation to render 80 seconds of animated 3D slices of a the quaternion. Check out the scene source.
/me looks forward for a real-time Julia4D explorer.
Not for myself, but if I had kids, certainly. Sugar is a desktop choice on Fedora and Ubuntu. Not sure about Debian.
