3D-Printed Car Takes Its First Test Drive 132

Posted by samzenpus
from the print-and-drive dept.
An anonymous reader points out this advancement in 3D printing. This week, at the International Manufacturing Technology Show (IMTS) in Chicago, Arizona-based automobile manufacturer Local Motors stole the show. Over the six day span of the IMTS, the company managed to 3D print and assemble an entire automobile, called the "Strati," live in front of spectators. Although the Strati is not the first ever car to be 3D printed, the advancements made by Local Motors with help from Cincinnati Inc, and Oak Ridge National Laboratory, have produced a vehicle in days rather than months.

Slashdot regular (and Couchsurfing.org volunteer) Bennett Haselton writes with a report that an anonymous prankster hacked the Couchsurfing.org website and sent spam to about 1 million members, snarkily advertising their commercial arch-rival Airbnb as "the new Couchsurfing." (Read on below for more on the breach.) As of now, the spam's been caught, but not the spammer.

It does, because teachers are expected to utilize methods that support common core

Could you please provide an example? I teach high school math and I have not felt pressured by the Common Core to use certain methods, so I'm genuinely curious. To me, it sounds like the real problem is with lousy administrators micromanaging teachers, not with the standards themselves.

Common Core isn't a curriculum, it's a set of standards. It does not have anything to do with homework, instruction methodology, grading rules, or anything like that. See for yourself. If your district is using shoddy curriculum like Engage NY, that is their fault.

I'm not saying that the CCSS are beyond criticism, but the criticism should be accurate.

Demonoid BitTorrent Tracker Apparently Back Online 134

Freshly Exhumed writes "TorrentFreak has broken the news that after more than a year of downtime the Demonoid tracker is back online. The tracker is linked to nearly 400,000 torrent files and more than a million peers, which makes it one of the largest working BitTorrent trackers on the Internet. There is no word yet on when the site will make a full comeback, but the people behind it say they are working to revive one of the most famous file-sharing communities. As the single largest semi-private BitTorrent tracker that ever existed, Demonoid used to offer a home to millions of file-sharers. Note that this is apparently the original Demonoid and not the d2 site that claims to be using the Demonoid database."

His advice ignores the benefits of leniency if you're guilty and you're almost positive you'll be caught anyway. For most of this discussion I've been focusing on the merits of talking to the police if you're innocent. But Officer Bruch also says that if people in the interrogation room answer questions and cooperate, then even if they're ultimately convicted, the police do testify to the judge that you were cooperative, and the judge can take that into account and reduce your prison sentence. That is at least theoretically another legitimate reason to violate Professor Duane's "Don't Talk To Cops" rule, if you're 99% sure that the police will find enough evidence to convict you anyway, you can hope for leniency by cooperating.

Would it not be more beneficial for your attorney to arrange some plea deal? As somebody who is not an expert on criminal law, I would keep my mouth shut until I talked to my attorney. I'd let the expert on criminal justice decide if it was worth confessing instead of hoping for the best.

Crowd-Funded Radio Beacon Will Message Aliens 196

astroengine writes "In the hope of uniting people around the globe in a long-duration project to send a radio 'message in a bottle' METI (Messaging Extraterrestrial Intelligence) signal, a crowd-funded project utilizing a refurbished radio telescope in California has begun its work. Lone Signal is a project initiated by scientists, businessmen and entrepreneurs to set up a continuous radio beacon from Earth. To support the operations of the Jamesburg Earth Station radio dish in Carmel Valley, Calif. (a dish built to support the Apollo 11 moon landing in 1969), a crowd-funding effort has been set up so that for a small fee, users can send images to the stars. If you're content with sending a text message, your first message is free. The radio dish's first target is Gliese 526, a red dwarf star 18 light-years from Earth, but the project will be considering other stellar targets believed to be harboring habitable worlds."
