Quantum Physics For Everybody 145

fiziko writes in with a self-described "blatant self-promotion" of a worthwhile service for those wishing to go beyond Khan Academy physics: namely Bureau 42's Summer School. "As those who subscribe to the 'Sci-Fi News' slashbox may know, Bureau 42 has launched its first Summer School. This year we're doing a nine-part series (every Monday in July and August) taking readers from high school physics to graduate level physics, with no particular mathematical background required. Follow the link for part 1."

New Linux Petabyte-Scale Distributed File System 132

An anonymous reader writes "A recent addition to Linux's impressive selection of file systems is Ceph, a distributed file system that incorporates replication and fault tolerance while maintaining POSIX compatibility. Explore the architecture of Ceph and learn how it provides fault tolerance and simplifies the management of massive amounts of data."

Comment The story from Google... (Score 4, Informative) 140

Hey, the fellows in netops asked me to clarify for you folks here's the story:

1e100.net is a Google-owned domain name used to identify the servers in our network. Following standard industry practice, we make sure each IP address has a corresponding hostname. Starting in October 2009, we started using a single domain name to identify our servers across all Google products, rather than use different product domains such as youtube.com, blogger.com, and google.com. We did this for two reasons: first, to keep things simpler, and second, to proactively improve security by protecting against potential threats such as cross-site scripting attacks. Most typical Internet users will never see 1e100.net, but we picked we picked a Googley name for it just in case (1e100 is scientific notation for 1 googol).

So there you go!

Comment Lots of comments on LWN.net's coverage (Score 5, Informative) 354

If you head over to LWN, we've already gone back and forth on this a bit. http://lwn.net/Articles/372419/. The short form is that if they don't like how we use the kernel, we're unlikely to be accepted upstream. It's all still released as source code to the world, but the mainline is not interested in most of what we've with to the kernel.

Comment Re:Wash your hands! (Score 1) 374

This is good advice, and gives me an opportunity to speak to the community at large: some of us who go to cons and are in a position to shake tons of hands politely decline. It's not because we're being dicks, it's because we know it's a good way to substantially decrease our chances of catching and spreading any germs.

Comment Oh, cruel irony (Score 2, Interesting) 374

I played the PAX Pandemic game, where the Enforcers handed out stickers to attendees that read [Carrier] [Infected] or [Immune] (There was also a [Patient Zero].

I got the [Immune] sticker, and by the time I got home on Monday, it was clear that I had the flu. I've had a fever between 100 and 104 all week that finally broke last night, but I'm going to the doctor today because I think whatever I had settled into my lungs. I'll tell him about the H1N1 outbreak and get tested if he wants to run the test, but at this point I think it's safe to assume that I was [Immune] to the Pig Plague, but definitely [Infected] with the damn PAX pox.

Even though it's been a week of misery, it was entirely worth it, and I don't regret going to PAX for a single second.

Solar Machine Spins Sunlight-Shaped Furniture 71

Mike writes "Austrian designers mischer'traxler have created a solar powered machine that makes an incredible array of furnishings that vary based on how much sunlight it receives over the course of a day. Titled 'The Idea of a Tree,' the machine spins spools of thread into stools, benches, containers, and lamp shades that wax and wane as the available sunlight shifts. Furniture created during cloudy winter days will be wrapped more slowly, causing it to be darker in color, thicker, and smaller than pieces created during the sun-soaked summer months."

Comment I am not producer for the Star Trek MMO (Score 5, Informative) 150

Hi, Eric Heimburg here (quoted in article).

I just wanted to clarify that although I was the producer for Asheron's Call 2, and have been lead engineer/lead designer for other MMO titles, I'm not affiliated with the upcoming Star Trek MMO. I worked on an earlier incarnation of the Star Trek MMO, when it was being made by Perpetual. (They went bankrupt and lost the license.) Somehow wires got crossed in the Wired article, and then they got crossed here, too.

This detail would be irrelevant and not worth mentioning, except that the company making the new Star Trek MMO is also making the superhero MMO "Champions Online" -- a direct competitor to CoH.

So there's been a meme of "he's a shill for the competition!" going on at Wired.com, which makes me sad. I am not a shill for any major MMO company... at the moment.

However, I am hyping my amazing blog at http://www.eldergame.com/ but a link to it always seems to get omitted in the article coverage...

Comment Re:Android (Score 2, Informative) 92

I'd like to point out that the Kogan phone folks could have adapted the code to the screen size, but it would have taken longer than their product plan would have allowed. So in that case, you are right, but if they had started the screen porting stuff earlier, then they probably could have shipped something like what they put on their website.

Let me remind you that the structure of the droid licensing is very clear: linux kernel, then apache/bsd all the way up from there (With a dollop of lgpl). You don't need googles permission to ship an android based device. There are some apps (maps comes to mind) that you do need googles permission to ship, but those are closed anyhow.

Lots of Pure Water Ice At Mars North Pole 176

brink2012 writes "Planum Boreum, Mars' north polar cap contains water ice 'of a very high degree of purity,' according to an international study. Using radar data from the SHARAD (SHAllow RADar) instrument on board the Mars Reconnaissance Orbiter (MRO), French researchers say the data point to 95 percent purity in the polar ice cap. The north polar cap is a dome of layered, icy materials, similar to the large ice caps in Greenland and Antarctica, consisting of layered deposits, with mostly ice and a small amount of dust. Combined, the north and south polar ice caps are believed to hold the equivalent of two to three million cubic kilometers (0.47-0.72 million cu. miles) of ice, making it roughly 100 times more than the total volume of North America's Great Lakes, which is 22,684 cu. kms (5,439 miles). The study was done by researchers at France's National Institute of Sciences of the Universe (Insu), using the Italian built SHARAD radar sounder on the US built MRO. SHARAD looks for liquid or frozen water in the first few hundreds of feet (up to 1 kilometer) of Mars' crust by using subsurface sounding. It can detect liquid water and profile ice. Mars southern polar cap was once thought to be carbon dioxide ice, but ESA's Mars Express confirmed that it is composed of a mixture of water and carbon dioxide. The study on Mars north polar cap appears in the journal Geophysical Research Letters, published by the American Geophysical Union."
