Aussie Scientists Build a Cluster To Map the Sky
Tri writes "Scientists at the Siding Spring Observatory have built a new system to map and record over 1 billion objects in the southern hemisphere sky. They collect 700 GB of data every night, which they then crunch down using some perl scripts and make available to other scientists through a web interface backed on Postgresql. 'Unsurprisingly, the Southern Sky Survey will result in a large volume of raw data — about 470 terabytes ... when complete. ... the bulk of the analysis of the SkyMapper data will be done on a brand new, next generation Sun supercomputer kitted out with 12,000 cores. Due to be fully online by December, the supercomputer will offer a tenfold increase in performance over the facility's current set up of two SGI machines, each with just under 3500 cores in total.'" -

Erlang's Creator Speaks About Its History and Prospects
Seal writes "Erlang, originally created at Ericsson in 1986, is a functional programming language which was released as open source around 10 years ago and flourished ever since. In this Q&A, Erlang creator Joe Armstrong talks about its beginnings as a control program for a telephone exchange, its flexibility and its modern day usage in open source programs. 'In the Erlang world we have over twenty years of experience with designing and implementing parallel algorithms. What we lose in sequential processing speed we win back in parallel performance and fault-tolerance,' Armstrong said. He also mentions how multi-core processors pushed the development of Erlang and the advantages of hot swapping." -
Australia's Largest Private Computer Collection In Pictures
Da Massive writes "UNIX PDP-7, a classic DEC PDP-8, the original IBM PC, Commodore's C64, Apple's Lisa, a MITS Altair 8800 made famous by Bill Gates, through to a working PDP-11 that plays the ADVENTURE and DUNGEON games. Max Burnet has got it all. Burnet has turned his home in the leafy suburbs of Sydney into arguably Australia's, if not the world's, largest private computer museum. Since retiring as director of Digital Equipment Corporation a decade ago, Burnet has converted his home into a snapshot of computer history. Every available space from his basement to the top floor of his two-storey home is covered with relics from the past. On top of his hardware collection are numerous punch cards, tape machines (including the original paper tape) and over 6000 computer reference books. So in demand is his collection that one Australian film called on him to recreate a computer setting (PDP-9) for a movie about the moon landing in 1969." -
NULL Pointer Exploit Excites Researchers
Da Massive writes "Mark Dowd's paper "Application-Specific Attacks: Leveraging the ActionScript Virtual Machine" has alarmed researchers. It points out techniques that promise to open up a class of exploits and vulnerability research previously thought to be prohibitively difficult. Already, the small but growing group of Information Security experts who have had the chance to read and digest the contents of the paper are expressing an excited concern depending on how they are interpreting it. While the Flash vulnerability described in the paper[PDF] has been patched by Adobe, the presentation of a reliable exploit for NULL pointer dereferencing has the researchers who have read the paper fascinated. Thomas Ptacek has an explanation of Dowd's work, and Nathan McFeters at ZDNet is 'stunned by the technical details.'"
