that an ocean may not be the source of the jets emanating from Saturn's moon
Research questions the moon's promise as a target in the search for life beyond Earth and has stirred controversy.
A chemical analysis of Enceladus, led by University of Colorado planetary scientist Nick Schneider, failed to detect sodium, an element scientists say should be in a body of water that has had billions of years of contact with rock. Spectral analysis with the Keck Telescope found no sodium in the plumes or in the vapour that's in orbit around the moon.
At stake is whether Saturn's moon could support alien life and is a worthy target for a US space agency (Nasa) exploratory mission to detect it. Such a mission to Enceladus is one of four currently under review for further development."

In addition to these classes of frameworks, we find that server-side Java-based (not XML-based) UI frameworks still have their place for two reasons: 1) security gained from not exposing UI logic to client, 2) easiness gained for direct access to all Java API:s, full unrestricted execution environment and lack of communication layer design.

The policy does not rule out proprietary software; but it does state a clear preference for FOSS where all other things are equal. The nine-page paper (PDF warning) does not purport to express any sort of legal or commercial commitment by the Ministry, but instead 'is believed to be consistent with existing MoJ policies.' The most salient reasons given for the preference are summarized in one sentence: 'Given two equivalent packages, one open and one proprietary, the OSS one would be the preferable choice for reasons of better supportability and lower lifecycle cost.'"

The giant corporation also said that they will start mass producing 65nm RSX chips for the Playstation 3 as soon as next month. Playstation 3's Cell CPU made a jump to 65nm fabrication process about a month ago, but the RSX GPU is currently still in 90nm process."

For months Mr Rudd has promised if elected he intends on bringing Australia up-to-date broadband capacity in establishing a Fiber to the Node (FTTN) infastructure nation wide.
What challenges await the new PM in establishing this? Telstra, who of course want to retain their monopoly over Australia's infastructure. Can Rudd and Telstra play nice in the interests of bringing Australia out of the stone age of DSL capabilities?
Stony Stevenson writes: In this new interview, Linus Torvalds is excited about solid-state drives, expects progress in graphics and wireless networking, and says the operating system is strong in virtualisation despite his personal lack of interest in the area.
Torvalds on Linux biggest strength: "When you buy an OS from Microsoft, not only you can't fix it, but it has had years of being skewed by one single entity's sense of the market. It doesn't matter how competent Microsoft — or any individual company — is, it's going to reflect that fact. In contrast, look at where Linux is used. Everything from cellphones and other small embedded computers that people wouldn't even think of as computers, to the bulk of the biggest machines on the supercomputer Top-500 list. That is flexibility. And it stems directly from the fact that anybody who is interested can participate in the development, and no single entity ends up being in control of where it all goes.

The Lupercal (a 26' high cave) was believed by the Romans to have been the place that Romulus and Remus (the founders of Rome) were rescued and suckled by a she-wolf. Now, whether these two people ever existed is another matter entirely, but even the place itself had descended into myths and legends, with no serious archaeologist believing it existed. Due to the extreme instability of Palatine Hill, where the cave exists, the archaeologists have not been inside. Instead, exploration has been by robots with cameras, endoscopes and laser scanners. These have mapped some amazing mosaics, marble artwork and an amazing white eagle."

It has been dead for the past few million years, but it's the thought that counts. Being a fossil, it will be hard to clone, though it would make a superb monster in the next Jurassic Park movie."
hereisnowhy writes: A giant fossilized claw discovered in Germany belonged to an ancient sea scorpion that was much bigger than the average man, an international team of geologists and archaeologists reported Tuesday. In a report in the Royal Society's journal Biology Letters, the team said the claw indicates that sea scorpion Jaekelopterus rhenania was almost 2.5 metres long, making it the largest arthropod — an animal with a segmented body, jointed limbs and a hard exoskelton — ever found. In the report, the authors said the scorpion exceeds previous size records for arthropods by almost half a metre.

Much like cut scenes, level loads are anathema to enjoyment of game play, and a throwback to the era of the Vic-20 and Commodore 64 when games were stored on cassette tapes, and memory was measured in kilobytes. So in this era of multi-megabyte and gigabyte memory and fast access storage devices why do we continue to have games that are dominated by the level structure, be they commercial (Portal, Team Fortress 2), independent (Darwinia) and amateur (Nethack, Angband)? Why do games still have levels?"

I am angry and frustrated that in 2007 this still happens with big stores (and I don't even want to imagine what application-level vulnerabilities they may have).
Besides writing them, should I call Visa or Mastercard? I thought it was mandatory for online merchants to use SSL and other basic security measures. Is it all hopeless?
