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?

Most modern programming languages do not consider white space characters (spaces, tabs and newlines) syntax, ignoring them, as if they weren't there. We consider this to be a gross injustice to these perfectly friendly members of the character set. Should they be ignored, just because they are invisible? Whitespace is a language that seeks to redress the balance.
Any non whitespace characters are ignored; only spaces, tabs and newlines are considered syntax. What are the advantages of Whitespace? Some things which are difficult in other languages are made much easier in Whitespace. Whitespace is a particularly useful language for spies. What does a typical Whitespace program look like? Below is an extract from a program which asks for a name then outputs it (see here for the full script. Where can I get it? There is a prototype Whitespace interpreter available on this site, go to this page to download it. Who is responsible? Faster & safer internet.

Royal Pingdom. Royal Pingdom » A look inside the fastest supercomputer in Europe. 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.
