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.

Solar Machine Spins Sunlight-Shaped Furniture Screenshot-sm 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."

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."

A Cautionary Tale of Open Source Social Technologies 330

eweekhickins writes "The 'country' drop-down menu on one organization's donations pages omits Israel as a country and includes 'Palestine.' Among other things, this means that Israelis can't donate to the organization from these pages; it also presents the risk of a PR nightmare for the organization. This EWeek story cautions that while basic Web 2.0 technologies combined with open source can be incredibly powerful and productive, they can also lead to disastrous results for an organization that isn't paying close enough attention."

Hawking Searching For Africa's Einsteins 276

nuke-alwin writes "Stephen Hawking has traveled to South Africa in search of Africa's Einsteins. The project will create Africa's first post-graduate center for math and physics. The British government has unfortunately decided not to back the project, which is hoping to fight poverty by identifying the kind of talent that can create wealth." Neil Turok is deeply involved as well; he was recently named to head the Perimeter Institute in Canada, whose server we brought to its knees this morning.

Submission + - MySQL Reverses Decision on Close Source (krow.net) 1

krow writes: "I am very happy to be announcing that MySQL will be forgoing close sourcing portions of the MySQL Server. Kaj has the official statement in his blog. No portion of the server of the sever will be closed source including backup, encryption, or any storage engines we ship. To quote Kaj "the encryption and compression backup features will be open source". This is a change from what was previously posted here on Slashdot. I've posted some additional thoughts on my own blog concerning how we keep open source from becoming crippleware. Word has it that we will also have a panel at this year's OSCON discussing this relevant topic. Contrary to the previous Slashdot post, this shows Sun's continued commitment to Open Source."

Submission + - 24h Open Source Coding Marathon Hackontest started (hackontest.org) 1

maemst writes: "Can you code 24 hours non-stop? Hackontest is a new Google-sponsored 24-hour programming competition between different open source projects. Its goals are to enhance Free Software projects according to user needs and to make visible how enthusiastically open source software is being developed. During the current online selection process users and developers of open source software may submit feature requests and rate and comment them. On Swiss national holiday August 1st, 2008 the Hackontest jury will pick the three most promising teams. They receive a free trip to Switzerland on September 24/25, 2008 to participate in the competition located at OpenExpo 2008 Zurich. Hacking 24 hours inside an etoy.CONTAINER, the teams and their virtually present communities will implement certain features based on the online ratings and jury selection. In the end, the Hackontest jury evaluates the code and awards the winners with a total of USD 8500. The jury is made up of 10 renowned open source contributors: Jeremy Alison (Samba), Jono Bacon (Ubuntu), Brian W. Fitzpatrick (Subversion), Martin F. Krafft (Debian), Alexander Limi (Plone), Federico Mena-Quintero (GNOME), Bram Moolenaar (vim), Bruce Perens (OSI founder), Lukas K. Smith (PHP) and Harald Welte (gpl-violations.org)."

The Real MIT Blackjack Mastermind 195

Wade Roush writes "21, the top movie at the box office last weekend, has everyone talking about the real identities of the MIT blackjack team members fictionalized in the movie and in the 2002 book, Bringing Down the House, on which the film is based. Last week a number of stories pointed to former MIT student and Las Vegas resident John Chang as the model for the Micky Rosa character, the club mastermind played in the movie by Kevin Spacey. But Boston-area Internet entrepreneur and real estate developer Bill Kaplan is saying that if anyone is the basis for Micky Rosa, it's him. Turns out Kaplan now battles the "e-mail churn" problem as CEO of Newton, MA, startup FreshAddress, which helps companies correct the outdated e-mail addresses in their customer databases."
