Submission + - Message for AMD: Open PSP Will Improve Security, Hinder Intel

futuristicrabbit writes: AMD has faced calls from Edward Snowden, Libreboot and the Reddit community to release the source code to the AMD Secure Processor (PSP), a network-capable co-processor which some believe has the capacity to act as a backdoor. Opening the PSP would not only have security benefits, but would provide AMD with a competitive advantage against rival chipmaker Intel. Lisa Su, the CEO of AMD, is reportedly seriously considering the change, and the community is working hard to make sure she makes the right decision.

Creeping Government Surveillance Now Without Warrants 78

CuteSteveJobs writes "The Age reports on creeping Australian government surveillance, beginning with the first operation launched on a baseless rumor. Six decades later the still-unaware victim read five months of transcripts with deep distress. Two decades ago few Australians would have consented to carrying a government-accessible tracking device, but phone and tablet data accessible without a warrant includes historic and real-time location data. In 2010-2011 there were 250,000 warrantless accesses by Federal agencies including ASIO, AFP, the Tax Office, Defence, Immigration, Citizenship, Health, Ageing, and Medicare. This is 18 times the rate of similar requests in the U.S."

Submission + - GNU Savannah Site Compromised (threatpost.com)

Trailrunner7 writes: A site belonging to the Savannah GNU free software archive was attacked recently, leading to a compromise of encrypted passwords and enabling the attackers to access restricted project material.

The compromise was the result of a SQL injection attack against the savannah.gnu.org site within the last couple of days and the site is still offline now. A notice on the site says that the group has finished the process of restoring all of the data from a clean backup and bringing up access to some resources, but is still in the middle of adjusting its security settings.

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.

Comment Animated quaternion (Score 4, Interesting) 255

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.

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.
