Gamma error in picture scaling. Best Monitor till now to view this page was a standard CRT Dell M783c Introduction There is an error in most photography scaling algorithms.
All software tested (August 2007) had the problem: The Gimp, Adobe Photoshop, CinePaint, Nip2, ImageMagick, GQview, Eye of Gnome, Paint and Krita. Also three different operating systems were used: Linux, Mac OS X and Windows. (Software that don't have the problem are listed in the Solutions chapter.) Photographs that have been scaled with these software have been degradated (see the examples). Below, a photograph of His Holiness the Dalai Lama was tuned to exploit the problem. This is what you probably will get once the image is scaled by your software: How much did you pay for that software?

In a recommendation to the Australian Government, Google warns that draconian anti-piracy measures could prove counterproductive.
Instead, the Government should promote new business models. "There is significant, credible evidence emerging that online piracy is primarily an availability and pricing problem," Google states. As in many other countries, online piracy is causing headaches for the Australian Government. A variety of anti-piracy strategies to deal with the problem have been suggested in recent years, but thus far without result. Late last year Australia’s Minister for Communication invited several companies to share their thoughts on the reduction of regulation in the communication sector.

Posted in Tech blog on June 2nd, 2009 by Pingdom What is now the fastest supercomputer in Europe was recently unveiled at a research institute in Jülich, Germany.
The computer, named Jugene, is capable of a massive one trillion computing operations per second. Here are some facts about the Jugene supercomputer: Based on IBM’s Blue Gene/P architecture.Computing capacity: 1 petaflop/second.That equals the computing power of more than 50,000 PCs.294,912 processor cores.Processor type: 32-bit PowerPC 450 at 850 MHz.144 terabytes of RAM.Mounted in 72 racks.Network bandwidth: 5.1 gigabyte/second with a 160 nanosecond latency.Power input: 2.2 megawatts. Wish we could get one of these for Pingdom. Packing those CPUs tightly together Each of the Jugene’s 72 racks has 1024 compute nodes, where each node has 2 gigabyte of RAM (totaling 144 terabytes for the whole system). For those of you who really want to dive into the nitty-gritty tech specs regarding Jugene’s setup, here’s more info. Adobe.
