Submission + - RSA keys factored, DMCA takedowns issued (sunshinepress.org) 2

An anonymous reader writes: A month ago, ticalc.org reported smart factoring of the 512-bit RSA key used by TI to sign their TI-83+ OS, which opens the door to seamless installation of open-source third-party OS on TI-83+ calculators. Since then, two other keys found in other TI calculators have been factored by a distributed effort. Several days ago, TI sent DMCA takedown notices to several sites mentioning the keys and their factors. All three keys factored so far have been posted to Wikileaks, and the effort to factor the remaining ones is going on.

Submission + - Military Helmet Design Contributes to Brain Damage (physicscentral.com)

BuzzSkyline writes: "Improvements in helmets have helped modern soldiers survive bullets and blasts that would have killed them in past wars. But increasing numbers of soldiers are suffering long lasting brain damage from explosions, partly as a result of what appears to be a flaw in helmet designs. Although the blast itself may not accelerate the brain inside a soldier's head enough to cause injury, shockwaves that make it through the space between a helmet and a soldier's head can cause the skull to flex, leading to ripples in the skull that can create damaging pressures in the brain. Simulations that relied on "code originally designed to simulate how a detonated weapon rattles a building or tank" could lead to new helmets that reduce the traumatic brain injuries that many soldiers suffer as a result of improvised explosive devices and other moderate-sized blasts. The research is due to be published in Physical Review Letters, but a preprint is currently available on the Physics ArXiv."

Submission + - Solar Roadways geta DOT funding. (autoblog.com) 1

mikee805 writes: Solar roadways a project to replace the over 25,000 square miles of road in the US with drivable solar panels just received $100K in funding from DOT for the 1st 12ft by 12ft prototype panel. Each panel consists of three layers: a base layer with data and power cabled running through it, an electronics layer with an array of LEDs, solar collectors, and capacitors and finally the glass road surface. With data and power cables the solar roadway was the potential to replace a lot of our aging infrastructure. With just a 15% efficiency this would project 3 time what US uses annually in energy! Also to head off a few problems the building costs are estimated to be competitive with traditional roads and the roads would heat themselves in the winter to keep snow from accumulating.

Comment Tooling and gaging (Score 1) 901

Finally some sanity. There are places in the tooling and gaging where the tolerances are tight and a change over to metric requires a complete re-engineering of the tolerance stackup.

Even still, there is no reason why the project should be driven by US customary units for every thing.

Re-state the external interfaces in Metric.
Build everything that is new in Metric.
Retain US customary units in unchanged assemblies.

DO THE PROGRAM LEVEL WORK IN METRIC.

Comment Re:What is so bad about "clean" coal? (Score 5, Informative) 464

The problem here is that utilities are currently trying to build new "Clean Coal" generating plants that have no carbon capture at all.

The "Clean Coal" phrase as Chu used it in the article is very different than the "Clean Coal" phrase used by my local utility trying to build a new plant. I would not mind Chu's "Clean Coal", but I do not want what the utilities are currently calling "Clean Coal".

NASA Names Space Station Treadmill After Colbert 383

willith writes "The SF Chronicle reports on the results of the International Space Station Node 3 naming contest (which we previously discussed). Comedian and fake-pundit Stephen Colbert conducted a bombastic write-in campaign and repeatedly urged his show's fan base (the 'Colbert Nation') to stuff the ballot box with his name, which resulted in 'Colbert' coming in first in the write-in contest with almost a quarter-million votes. Although the Node 3 component will not be named 'Colbert' — NASA has instead chosen to call it 'Tranquility' — one of the Node 3 components will bear the honor: the second ISS treadmill, which will be installed in Node 3, will be named the Combined Operational Load Bearing External Resistance Treadmill. The formal announcement was made on the air yesterday at 22:30 EDT on the Colbert Report by astronaut Sunita Williams."

Microsoft Office 2007 In Linux With WINE 224

Kenneth Reitz writes "Wouldn't it be lovely to have a nice, clean installation of Microsoft's Office 2007 Suite to run on your Ubuntu Linux Distribution? For some people, this is the only thing that truly holds them back from an all-Linux environment ... But not anymore! We have compiled a nice, concise set of instructions to help guide you along."

Comment Re:First chance to see if Obama is a retard or not (Score 1) 189

The DIRECT team has written quite a bit about what is needed to change over from the Ares I/V architecture to the Jupiter architecture. While we would be throwing away all of the design work on the Ares I upper stage, making the change at this point still has a quicker return to flight. Having better rockets is a side benefit.

The J2 rocket work and 5 segment SRB work will come in handy for building the Jupiter 232.

There is no reason to 'stay the course' of the AresI/V. It is time to choose the rocket that is faster, better, and cheaper.

Comment Re:Space Elevator (Score 1) 189

A space elevator is a great idea. We should build one as soon as we can produce enough unobtainium to make the tether.

We should be doing the materials research needed for a space elevator, but the question now is about how to get to space for the next ten years. A space elevator will (almost certainly) not be build-able in that time, but we can launch rockets.

Right now we need rockets, the question is which rocket. Space elevators, fusion drives, and other fanciful stuffs are things we should think about and research, but they are not the things we can build today.

Comment Re:Congrats SpaceX (Score 5, Informative) 182

Unless NASA releases money for COTS-D very soon, we will still have a manned launch gap. The Falcon 9 and Dragon are man rated, but to launch people into using the Falcon 9 and Dragon, you need much more. You need a Launch Escape System and a Emergency Egress System. Neither of these is currently in development at SpaceX and both have a long lead time to develop.

Without the additional COTS-D money to start development on these systems, SpaceX will not carry people until they find the money from other sources to fund these development efforts.

Behind the Cogent-Sprint Depeering 325

An anonymous reader brings an update to Sprint's depeering with Cogent, which we discussed a few days back — namely, Sprint's side of the story. According to them, no free peering contract had ever existed, Cogent refused to pay the bills to exchange traffic, and after a year Sprint gave Cogent 30 days notice of their intent to disconnect. During this 30-day period, when one or two connections (out of ten) per week were shut down, Cogent made no alternate arrangements to alleviate the impact on their customers — but they had a press release ready when Sprint snipped the final wire. It will be interesting to see how Cogent responds.

Submission + - SpaceX Confirms Falcon 1 Vehicle Lost 1

Stormwave0 writes: Diane Murphy, VP of Marketing and Communications, confirmed in a teleconference that the Falcon 1 launch 3 vehicle was lost during launch Saturday. Just after 2 minutes into launch, a problem occurred with the stage separation, causing the stages to be stuck together. Company founder Elon Musk stated that the failure will not have a major impact on the company's finances. SpaceX is still investigating the problem but does not anticipate any delays in the rocket's launch schedule. Launch 4 is currently scheduled for the fourth quarter of this year.

DHS Allowed To Take Laptops Indefinitely 1123

andy1307 writes with a Washington Post story giving details of Department of Homeland Security policies for border searches of laptops and other electronic devices (as well as papers). (We have been discussing border searches for a while now.) DHS says such procedures have long been in place but were "disclosed last month because of public interest in the matter," according to the article. Here is a link to the policy (PDF, 5 pages). "Federal agents may take a traveler's laptop or other electronic device to an off-site location for an unspecified period of time without any suspicion of wrongdoing, as part of border search policies the Department of Homeland Security recently disclosed. Also, officials may share copies of the laptop's contents with other agencies and private entities for language translation, data decryption, or other reasons, according to the policies, dated July 16 and issued by two DHS agencies, US Customs and Border Protection and US Immigration and Customs Enforcement... DHS officials said that the newly disclosed policies — which apply to anyone entering the country, including US citizens — are reasonable and necessary to prevent terrorism... The policies cover 'any device capable of storing information in digital or analog form,' including hard drives, flash drives, cell phones, iPods, pagers, beepers, and video and audio tapes. They also cover 'all papers and other written documentation,' including books, pamphlets and 'written materials commonly referred to as "pocket trash..."'"
