6.7 Meter Telescope To Capture 30 Terabytes Per Night 67

Lumenary7204 writes "The Register has a story about the Large Synoptic Survey Telescope, a project to build a 6.7 meter effective-diameter ground-based telescope that will be used to map some of the faintest objects in the night sky. Jeff Kantor, the LSST Project Data Manager, indicates that the telescope should be in operation by 2016, will generate around 30 terabytes of data per night, and will 'open a movie-like window on objects that change or move on rapid timescales: exploding supernovae, potentially hazardous near-Earth asteroids, and distant Kuiper Belt Objects.' The end result will be a 150 petabyte database containing one of the most detailed surveys of the universe ever undertaken by a ground-based telescope. The telescope's 8.4 meter mirror blank was recently unveiled at the University of Arizona's Mirror Lab in Tucson."

Norwegian Standards Body Members Resign Over OOXML 208

tsa writes "Ars Technica reports that 13 of the 23 members from the technical committee of the Norwegian standards body, the organization that manages technical standards for the country, have resigned because of the way the OOXML standardization was handled. We've previously discussed Norway's protest and ISO's rejection of other appeals. From the article: 'The standardization process for Microsoft's office format has been plagued with controversy. Critics have challenged the validity of its ISO approval and allege that procedural irregularities and outright misconduct marred the voting process in national standards bodies around the world. Norway has faced particularly close scrutiny because the country reversed its vote against approval despite strong opposition to the format by a majority of the members who participated in the technical committee.'"

Safari 3 vs. Firefox 2 and IE7 559

Bobcat writes "Ars Technica has a 'first look' at Safari for Windows, which is interesting because it's written from the perspective of someone new to Safari. It was tested against Firefox 2 and IE7 and aside from the slightly faster page loading, Ars didn't find much to recommend it to Windows users. 'The modest increase in rendering performance is hardly worth the deficiencies, and Safari's user interface simply doesn't provide the usability or flexibility of competing products. If the folks at Apple think that providing Windows users with a taste of Mac OS X through Safari is going to entice them to buy a Mac, it's going to take a better effort than the Safari 3 beta. Even if the final release is more polished and completely bug-free, it still won't be as powerful or feature-loaded as Opera or Firefox.'"

Submission + - Matter travelling at light speed

mcgrew writes: "New Scientist reports that they have clocked matter travelling at 99.999% of the speed of light.

The fastest flows of matter in the universe shoot out of dying stars at more than 99.999% the speed of light, new observations reveal.

When a massive star runs out of fuel, it collapses to form a black hole or a neutron star. In the process, some of the matter from the star also explodes outwards at blistering speeds, producing an intense burst of gamma rays and other radiation
If you had a space ship this fast, you could get to Mars in ten minutes, depending on where Mars and Earth were at the time! Of course, the acceleration and radiation would kill you..."
