Laser Camera Can See Around Corners 97

Posted by timothy from the good-skill-to-pick-up dept.
Hugh Pickens writes "Researchers at MIT have developed a laser camera that can 'see' around corners and take pictures of a scene not in its direct line of sight. The camera system fires extremely short bursts of light that can reflect off one object, such as the open door of a room, and then off a second object inside the room before reflecting back to the first object and being captured by the camera, after which algorithms can use the information to reconstruct the hidden scene exploiting the fact that it is possible to capture light at extremely short time scales, about one quadrillionth of a second. By continuously gathering light and computing the time and distance that each pixel has traveled, the camera creates a '3D time-image' of the scene it can't directly see. 'It's like having X-ray vision without the X-rays,' says Professor Ramesh Raskar. 'We're going around the problem rather than going through it.'"

Simple Virus For Teaching? 366

Posted by samzenpus from the my-first-malware dept.
ed1023 writes "Currently I am teaching a 101 class on computers. It is more of a 'demystifying the black box' type of class. The current topic is computer viruses; I am looking for a virus with which I can infect the lab computers (only connected to local network, no outside network connection) that would be easy for the students to remove by hand. Can the Slashdot community point me in any directions? Is there an executable out there that would work, or do I try to write one myself, or is there one that is written that I can compile myself?"

I can second this. MP is really great if you have an extensive collection of video, tv-rips, photos and/or music. Only thing I haven't been able to do with it well is web-streaming (NetFlix, etc.) I use Boxee for that.

Setup and media indexing is pretty simple, if a bit time consuming. There are several good walk-throughs on the MP forums.

I have it running on my HTPC, and even my wife is happy with it in the living room. As far as XBMC goes, MP is a fork from a couple of years ago, so they have a lot in common. I've found that the movie/tv-show handling is better with MP, especially with the Streamed MP skin.

for 30$/gb/month they are probably using the "outsource the backup to a monastery where teams of monks slave tirelessly, day-and-night, to hand transcribe all your data onto painstakingly hand illuminated parchment made out of the skin of Cashmere goats born during the summer solstice in alternating leap years" backup strategy. It's all a question of quality.

New Material Can Store Vast Amounts of Energy 253

Posted by timothy from the ok-let's-squash-more-stuff dept.
ElectricSteve writes "Using super-high pressures similar to those found deep in the Earth or on a giant planet, researchers from Washington State University (WSU) have created a compact, never-before-seen material capable of storing vast amounts of energy. Described by one of the researchers as 'the most condensed form of energy storage outside of nuclear energy,' the material holds potential for creating a new class of energetic materials or fuels, an energy storage device, super-oxidizing materials for destroying chemical and biological agents, and high temperature superconductors."

Seriously?

I mean are you really going to rush breathlessly to the defense of a breathless guy with only a tenuous connection to the science and engineering involved in this disaster? One who can't even spell/fact check his own friggin' tag-line? When he's name-dropping? About friggin' astronauts? That his dad supposedly got to the moon?

Or did I miss the legendary but forgotten Apollo astronaut, "NEAL" Armstrong somewhere in all the ridiculous hype around NEIL Alden Armstrong?

Dude, you need to turn in your nerd card.

I was looking for something like this a few years ago when I was working on a carrier-grade scalable multi-tenant CC project. Pretty much the only thing I could find was from SolSoft (which has morphed somehow into LogLogic in the meantime) called "Solsoft Security Change Manager". In the end, we decided to go with the high-paid admin approach so we didn't do any serious testing, but it might be what you are looking for. FWIW, I got the tip for Solsoft from a guy who worked on Netfilter.

Utah Considers Warrantless Internet Subpoenas 234

Posted by kdawson from the mission-creep dept.
seneces writes "The Utah State Legislature is considering a bill granting the Attorney General's Office the ability to demand customer information from Internet or cell phone companies via an administrative subpoena, with no judicial review (text of the HB150). This represents an expansion of a law passed last year, which granted that ability when 'it is suspected that a child-sex crime has been committed.' Since becoming law, last year's bill has led to more than one non-judicial request per day for subscriber information. Pete Ashdown, owner of a local ISP and 2006 candidate for the US Senate, has discussed his position and the effects of this bill."
