The Science Behind Powdered Alcohol 176

Daniel_Stuckey (2647775) writes "Last week, the US Alcohol and Tobacco Tax and Trade Bureau approved Palcohol, a powdered alcohol product that you can either use to turn water into a presumably not-that-delicious marg or to snort if you don't care too much about your brain cells. It's the first time a powdered alcohol product has been approved for sale in the US, but not the first time someone has devised one, and such products have been available in parts of Europe for a few years now. Now you may be wondering, as I was, how the heck do you go about powdering alcohol? As you might expect, there's quite a bit of chemistry involved, but the process doesn't seem overly difficult; we've known how to do it since the early 1970s, when researchers at the General Foods Corporation (now a subsidiary of Kraft) applied for a patent for an 'alcohol-containing powder.'" It turns out the labels were issued in error, so don't expect it to be available soon. But it does appear to be a real thing that someone is trying to have approved.

Intentional Backdoor In Consumer Routers Found 236

New submitter janoc (699997) writes about a backdoor that was fixed (only not). "Eloi Vanderbeken from Synacktiv has identified an intentional backdoor in a module by Sercomm used by major router manufacturers (Cisco, Linksys, Netgear, etc.). The backdoor was ostensibly fixed — by obfuscating it and making it harder to access. The original report (PDF). And yeah, there is an exploit available ..." Rather than actually closing the backdoor, they just altered it so that the service was not enabled until you knocked the portal with a specially crafted Ethernet packet. Quoting Ars Technica: "The nature of the change, which leverages the same code as was used in the old firmware to provide administrative access over the concealed port, suggests that the backdoor is an intentional feature of the firmware ... Because of the format of the packets—raw Ethernet packets, not Internet Protocol packets—they would need to be sent from within the local wireless LAN, or from the Internet service provider’s equipment. But they could be sent out from an ISP as a broadcast, essentially re-opening the backdoor on any customer’s router that had been patched."

Eyes Over Compton: How Police Spied On a Whole City 190

Advocatus Diaboli (1627651) writes with some concerning news from the Atlantic. From the article: "In a secret test of mass surveillance technology, the Los Angeles County Sheriff's Department sent a civilian aircraft over Compton, California, capturing high-resolution video of everything that happened inside that 10-square-mile municipality. Compton residents weren't told about the spying, which happened in 2012. 'We literally watched all of Compton during the times that we were flying, so we could zoom in anywhere within the city of Compton and follow cars and see people,' Ross McNutt of Persistence Surveillance Systems told the Center for Investigative Reporting, which unearthed and did the first reporting on this important story. The technology he's trying to sell to police departments all over America can stay aloft for up to six hours. Like Google Earth, it enables police to zoom in on certain areas. And like TiVo, it permits them to rewind, so that they can look back and see what happened anywhere they weren't watching in real time."

404-No-More Project Seeks To Rid the Web of '404 Not Found' Pages 72

First time accepted submitter blottsie (3618811) writes "A new project proposes to do away with dead 404 errors by implementing a new HTML attribute that will help access prior versions of hyperlinked content. With any luck, that means that you'll never have to run into a dead link again. ... The new feature would come in the form of introducing the mset attribute to the <a> element, which would allow users of the code to specify multiple dates and copies of content as an external resource." The mset attribute would specify a "reference candidate:" either a temporal reference (to ease finding the version cited on e.g. the wayback machine) or the url of a static copy of the linked document.

Intel Pushes Into Tablet Market, Pushes Away From Microsoft 110

jfruh (300774) writes "The Wintel cartel appears to be well and truly dead, as Intel chases after ARM with grim determination into the rapidly growing world of Android tablets. 'Our mix of OSes reflects pretty much what you see in the marketplace,' the company's CEO said, a nice way of saying they see more potential growth from white-box Chinese tablet makers than from Microsoft Surface. Intel managed to ship 5 million tablet chips in the first quarter of the year, although plunging PC sales meant that company profit overall was still down."

Astronomers Solve Puzzle of the Mountains That Fell From Space 51

KentuckyFC (1144503) writes "Iapetus, Saturn's third largest moon, was first photographed by the Cassini spacecraft on 31 December 2004. The images created something of a stir. Clearly visible was a narrow, steep ridge of mountains that stretch almost halfway around the moon's equator. The question that has since puzzled astronomers is how this mountain range got there. Now evidence is mounting that this mountain range is not the result of tectonic or volcanic activity, like mountain ranges on other planets. Instead, astronomers are increasingly convinced that this mountain range fell from space. The latest evidence is a study of the shape of the mountains using 3-D images generated from Cassini data. They show that the angle of the mountainsides is close to the angle of repose, that's the greatest angle that a granular material can form before it landslides. That's not proof but it certainly consistent with this exotic formation theory. So how might this have happened?

Astronomers think that early in its life, Iapetus must have been hit by another moon, sending huge volumes of ejecta into orbit. Some of this condensed into a new moon that escaped into space. However, the rest formed an unstable ring that gradually spiraled in towards the moon, eventually depositing the material in a narrow ridge around the equator. Cassini's next encounter with Iapetus will be in 2015 which should give astronomers another chance to study the strangest mountain range in the Solar System."

Lavabit Loses Contempt Appeal 128

After being forced to turn over encryption keys (being held in contempt of court for several weeks after initially refusing to comply), secure mail provider Lavabit halted all operations last year. With the assistance of the EFF, an appeal was mounted. Today, the appeals court affirmed the district court decision and rejected the appeal. From Techdirt: "The ruling does a decent job explaining the history of the case, which also details some of the (many, many) procedural mistakes that Lavabit made along the way, which made it a lot less likely it would succeed here. ... The procedural oddities effectively preclude the court even bothering with the much bigger and important question of whether or not a basic pen register demand requires a company to give up its private keys. The hail mary attempt in the case was to argue that because the underlying issues are of 'immense public concern' (and they are) that the court should ignore the procedural mistakes. The court flatly rejects that notion: 'exhuming forfeited arguments when they involve matters of “public concern” would present practical difficulties. For one thing, identifying cases of a “public concern” and “non-public concern” –- divorced from any other consideration –- is a tricky task governed by no objective standards..... For another thing, if an issue is of public concern, that concern is likely more reason to avoid deciding it from a less-than-fully litigated record....'"

Microsoft Brings Office Online To Chrome OS; Ars Reviews Windows Phone 8.1 69

SmartAboutThings (1951032) writes "While we are still waiting for the official Windows 8.1 touch-enabled apps to get launched on the Windows Store, Microsoft went and decided that it's time to finally bring the Office online apps to the Chrome Web Store, instead. Thus, Microsoft is making the Web versions of its Word, Excel, PowerPoint and OneNote apps available to users through the Chrome Web Store and also improving all of them with new features, along with several bug fixes and performance improvements." More on the Microsoft front: an anonymous reader wrote in with a link to Ars Technica's review of the upcoming Windows Phone 8.1 release: "It is a major platform update even if it is just a .1 release. Updates include the debut of Cortana, using the same kernel as Windows 8.1 and the Xbox One, a notebook reminder app, inner circle friend management, IE 11, Nokia's camera app by default, lock screen and background customizations, a much improved email client with calendar support, more general Windows 8.1 API inclusion for better portability, and a notification center. Ars rated it more of a Windows Phone 9 release than .1 update."

Retired SCOTUS Justice Wants To 'Fix' the Second Amendment 1633

CanHasDIY (1672858) writes "In his yet-to-be-released book, Six Amendments: How and Why We Should Change the Constitution, John Paul Stevens, who served as an associate justice of the Supreme Court for 35 years, believes he has the key to stopping the seeming recent spate of mass killings — amend the Constitution to exclude private citizens from armament ownership. Specifically, he recommends adding 5 words to the 2nd Amendment, so that it would read as follows: 'A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms when serving in the Militia shall not be infringed.'

What I find interesting is how Stevens maintains that the Amendment only protects armament ownership for those actively serving in a state or federal military unit, in spite of the fact that the Amendment specifically names 'the People' as a benefactor (just like the First, Fourth, Ninth, and Tenth) and of course, ignoring the traditional definition of the term militia. I'm personally curious about his other 5 suggested changes, but I guess we'll have to wait until the end of April to find out."

Bill Gates Patents Detecting, Responding To "Glassholes" 140

theodp (442580) writes "As Google Glass goes on sale [ed: or rather, went on sale] to the general public, GeekWire reports that Bill Gates has already snagged one patent for 'detecting and responding to an intruding camera' and has another in the works. The invention proposes to equip computer and device displays with technology for detecting and responding to any cameras in the vicinity by editing or blurring the content on the screen, or alerting the user to the presence of the camera. Gates and Nathan Myhrvold are among the 16 co-inventors of the so-called Unauthorized Viewer Detection System and Method, which the patent application notes is useful 'while a user is taking public transportation, where intruding cameras are likely to be present.' So, is Bill's patent muse none other than NYC subway rider Sergey Brin?" A more cynical interpretation: closing the analog hole. Vaguely related, mpicpp pointed out that Google filed a patent for cameras embedded in contact lenses.

Submission + - Maynard Launches As Lightweight Wayland Desktop For The Pi (phoronix.com)

An anonymous reader writes: Maynard has been announced as a joint Collabora and Raspberry Pi Foundation venture to create a lightweight Wayland desktop suitable for running on the Rasbperry Pi. Maynard can run on the Raspberry Pi as well as conventional desktops while being very lightweight, except it goes without support for XWayland to run legacy X11 apps and it also doesn't handle GTK apps well.

Submission + - Nokia had production ready web tablet 13 years ago, killed just before launch (digitoday.fi)

An anonymous reader writes: Sad story: Nokia created M510 tablet running EPOC (later to be renamed as Symbian) thirteen years ago. It was fully production ready and they produced thousand units just before it was cancelled because market research proved there wasn't demand for the device. The team got devices for themselves and the rest were destroyed and the team was fired. The lesson: Don't try to be pioneer if you're relying on market research studies.

Mt. Gox Ordered Into Liquidation 44

An anonymous reader writes "The Japanese edition of The Wall Streeet Journal reports that Mt. Gox has filed for liquidation under Japanese bankruptcy law (link to article in Japanese, U.S. version may be paywalled). The article cites a 'related party' as saying that Mt. Gox was unable to work out how to deal with creditors spread out all over the globe, nor design a realistic rebuilding plan. The article adds a comment from the company lawyer: Mark Karpeles will not be attending the bankruptcy court hearing in the United States scheduled for April 17th." The announcement from Mt.

Pollution In China Could Be Driving Freak Weather In US 158

Hugh Pickens DOT Com (2995471) writes "Jonathan Kaiman reports at The Guardian that China's air pollution could be intensifying storms over the Pacific Ocean and altering weather patterns in North America leading to more ... warm air in the mid-Pacific moving towards the north pole. 'Mid-latitude storms develop off Asia and they track across the Pacific, coming in to the west coast of the U.S.,' says Ellie Highwood, a climate physicist at the University of Reading. 'The particles in this model are affecting how strong those storms are, how dense the clouds are, and how much rainfall comes out of those storms.' Fossil fuel burning and petrochemical processing in Asia's rapidly developing economies lead to a build-up of aerosols, fine particles suspended in the air. Typically, aerosol formation is thought of as the antithesis to global warming: it cools our Earth's climate. But researchers say, too much of any one thing is never good. 'Aerosols provide seeds for cloud formation. If you provide too many seeds, then you fundamentally change cloud patterns and storm patterns,' says co-author Renyi Zhang. China's leaders are aware of the extent of the problem and will soon revise China's environmental protection law for the first time since 1989 ... 'The provisions on transparency are probably the most positive step forward,' says Alex Wang, expert in Chinese environmental law at UCLA. 'These include the requirement that key polluters disclose real-time pollution data.'"

Submission + - How do you revoke and re-issue a biometric credential? (technicalnotebook.com)

technicalnotebook writes: An interesting thought to come out of all the media surrounding Heartbleed over the last week. What would happen if the main mechanism of authentication used today was biometric authentication... this is not something that could simply be revoked and re-issued if your credentials were compromised.

So I thought I would pose this to the brains trust that is Slashdot, what *could* we do if something similar to Heartbleed happened following the more mainstream adoption of biometric authentication (assuming that in certain cases the credentials were stored server-side rather than locally for verification).

Interesting puzzle to ponder (and I would love to hear Slashdotter's thoughts).
