Ask Slashdot: Preparing an Android Tablet For Resale?

3 hours 22 min ago
UrsaMajor987 (3604759) writes I have a Asus Transformer tablet that I dropped on the floor. There is no obvious sign of damage but It will no longer boot. Good excuse to get a newer model. I intend to sell it for parts (it comes with an undamaged keyboard) or maybe just toss it. I want to remove all my personal data. I removed the flash memory card but what about the other storage? I know how to wipe a hard drive, but how do you wipe a tablet? If you were feeling especially paranoid, but wanted to keep the hardware intact for the next user, what would you do?

Lots Of People Really Want Slideout-Keyboard Phones: Where Are They?

4 hours 3 min ago
Bennett Haselton writes: I can't stand switching from a slideout-keyboard phone to a touchscreen phone, and my own informal online survey found a slight majority of people who prefer slideout keyboards even more than I do. Why will no carrier make them available, at any price, except occasionally as the crummiest low-end phones in the store? Bennett's been asking around, of store managers and users, and arrives at even more perplexing questions. Read on, below.

US States Edge Toward Cryptocoin Regulation

4 hours 44 min ago
SonicSpike points out an article from the Pew Charitable Trusts' Research & Analysis department on the legislation and regulation schemes emerging in at least a few states in reaction to the increasing use of digital currencies like Bitcoin. A working group called the Conference of State Bank Supervisors’ Emerging Payments Task Force has been surveying the current landscape of state rules and approaches to digital currencies, a topic on which state laws are typically silent. In April, the task force presented a model consumer guidance to help states provide consumers with information about digital currencies. A number of states, including California, Massachusetts and Texas, have issued warnings to consumers that virtual currencies are not subject to “traditional regulation or monetary policy,” including insurance, bonding and other security measures, and that values can fluctuate dramatically. ... The article focuses on the high-population, big-economy states of New York, California and Texas, with a touch of Kansas -- but other states are sure to follow. Whether you live in the U.S. or not, are there government regulations that you think would actually make sense for digital currencies?

Internet Census 2012 Data Examined: Authentic, But Chaotic and Unethical

5 hours 26 min ago
An anonymous reader writes "A team of researchers at the TU Berlin and RWTH Aachen presented an analysis of the Internet Census 2012 data set (here's the PDF) in the July edition of the ACM Sigcomm Computer Communication Review journal. After its release on March 17, 2013 by an anonymous author, the Internet Census data created an immediate media buzz, mainly due to its unethical data collection methodology that exploited default passwords to form the Carna botnet. The now published analysis suggests that the released data set is authentic and not faked, but also reveals a rather chaotic picture. The Census suffers from a number of methodological flaws and also lacks meta-data information, which renders the data unusable for many further analyses. As a result, the researchers have not been able to verify several claims that the anonymous author(s) made in the published Internet Census report. The researchers also point to similar but legal efforts measuring the Internet and remark that the illegally measured Internet Census 2012 is not only unethical but might have been overrated by the press."

Oracle Offers Custom Intel Chips and Unanticipated Costs

6 hours 7 min ago
jfruh (300774) writes "For some time, Intel has been offering custom-tweaked chips to big customers. While most of the companies that have taken them up on this offer, like Facebook and eBay, put the chips into servers meant for internal use, Oracle will now be selling systems running on custom Xeons directly to end users. Those customers need to be careful about how they configure those systems, though: in the new Oracle 12c, the in-memory database option, which costs $23,000 per processor, is turned on by default."

Attackers Install DDoS Bots On Amazon Cloud

6 hours 49 min ago
itwbennett (1594911) writes "Attackers are exploiting a vulnerability in distributed search engine software Elasticsearch to install DDoS malware on Amazon and possibly other cloud servers. Last week security researchers from Kaspersky Lab found new variants of Mayday, a Trojan program for Linux that's used to launch distributed denial-of-service (DDoS) attacks. The malware supports several DDoS techniques, including DNS amplification. One of the new Mayday variants was found running on compromised Amazon EC2 server instances, but this is not the only platform being misused, said Kaspersky Lab researcher Kurt Baumgartner Friday in a blog post."

Google's Mapping Contest Draws Ire From Indian Government

7 hours 28 min ago
hypnosec writes with news that India's Central Bureau of Investigation has ordered a preliminary enquiry (PE) against Google for violating Indian laws by mapping sensitive areas and defence installations in the country. As per the PE, registered on the basis of a complaint made by the Surveyor General of India's office to the Union Home Ministry, Google has been accused of organizing a mapping competition dubbed 'Mapathon' in February-March 2013 without taking prior permission from Survey of India, country's official mapping agency. The mapping competition required citizens to map their neighbourhoods, especially details related to hospitals and restaurants. The Survey of India (SoI), alarmed by the event, asked the company to share its event details. While going through the details the watchdog found that there were several coordinates having details of sensitive defence installations which are out of the public domain."

Stanford Team Creates Stable Lithium Anode Using Honeycomb Film

8 hours 6 min ago
puddingebola (2036796) writes "A team at Stanford has created a stable Lithium anode battery using a carbon honeycomb film. The film is described as a nanosphere layer that allows for the expansion of Lithium during use, and is suitable as a barrier between anode and cathode. Use of a lithium anode improves the coulombic efficiency and could result in longer range batteries for cars." The linked article suggests that the 200-mile-range, $25,000 electric car is a more realistic concept with batteries made with this technology, though some people are more interested in super-capacity phone batteries.

Build Your Own Gatling Rubber Band Machine Gun

8 hours 35 min ago
New submitter melarky (3767369) writes This is a fun weekend project that most nerds will appreciate. Step by step instructions and also a handy video will make the construction of this project fast and easy. I have seen lots of plans for sale (or actual guns/kits for sale), but couldn't seem to find any plans for free. I played around with a few different designs (even cut my first few on a homemade CNC machine) and finally landed on this design. I made the guide more accessible to the general public (no need for a CNC machine here), so if you've ever dreamed of ending friendships because of hundreds of rubber band welts, now's your chance! We'd like to see your home-made projects, too.

World's Largest Amphibious Aircraft Goes Into Production In China

9 hours 2 min ago
stephendavion (2872091) writes "Chinese aircraft manufacturer China Aviation Industry General Aircraft (CAIGA) has started trial production of its TA600 amphibious aircraft, claimed to be the world's largest of its kind. With an expected maiden flight late next year, the Chinese plane would replace Japan's ShinMaywa US-2 short takeoff and landing (STOL) aircraft as the largest of its kind globally." Take a look at a side profile illustration of the CA-600, on this Korean language page. The TA600 has a huge maximum takeoff weight of 53.5 tons, but looks a bit puny compared to Howard Hughes' H-4 Hercules.

The Oculus Rift DK2: In-Depth Review (and Comparison To DK1)

9 hours 41 min ago
Benz145 (1869518) writes "The hotly anticipated Oculus Rift DK2 has begun arriving at doorsteps. The DK2s enhancements include optical positional tracking and a higher resolution panel, up from 1280×800 to 1920×1080 (1080p) and moved to a pentile-matrix OLED panel for display duties. This means higher levels of resolvable detail and a much reduced screen door effect. The panel features low persistence of vision, a technology pioneered by Valve that aims to cut motion artefacts by only displaying the latest, most correct display information relative to the user's movements – as users of the DK1 will attest, its LCD panel was heavily prone to smearing, things are now much improved with the DK2."

Suddenly Visible: Illicit Drugs As Part of Silicon Valley Culture

10 hours 23 min ago
The recent death by overdose of Google executive Timothy Hayes has drawn attention to the phenomenon of illegal drug use (including abuse of prescription painkillers) among technology workers and executives in high-pay, high-stress Silicon Valley. The Mercury News takes a look at the phenomenon; do the descriptions of freely passed cocaine, Red Bull as a gateway drug, and complacent managers match your own workplace experiences? From the Mercury News article: "There's this workaholism in the valley, where the ability to work on crash projects at tremendous rates of speed is almost a badge of honor," says Steve Albrecht, a San Diego consultant who teaches substance abuse awareness for Bay Area employers. "These workers stay up for days and days, and many of them gradually get into meth and coke to keep going. Red Bull and coffee only gets them so far." ... Drug abuse in the tech industry is growing against the backdrop of a national surge in heroin and prescription pain-pill abuse. Treatment specialists say the over-prescribing of painkillers, like the opioid hydrocodone, has spawned a new crop of addicts -- working professionals with college degrees, a description that fits many of the thousands of workers in corporate Silicon Valley. Increasingly, experts see painkillers as the gateway drug for addicts, and they are in abundance. "There are 1.4 million prescriptions ... in the Bay Area for hydrocodone," says Alice Gleghorn with the San Francisco Department of Public Health. "That's a lot of pills out there."

Microsoft's Nokia Plans Come Into Better Focus

12 hours 38 min ago
Forbes has an update on what sort of future Nokia faces, as Microsoft reveals a strategy for making sense of the acquisition: [Microsoft EVP of devices Stephen] Elop laid out a framework for cost cuts in a memo to employees on July 17. Devices would focus on high and low cost Windows smartphones, suggesting a phasing out of feature phones and Android smartphones. Two business units, smart devices and mobile phones, would become one, thereby cutting overlap and overhead. Microsoft would reduce engineering in Beijing and San Diego and unwind engineering in Oulu, Finland. It would exit manufacturing in Komarom, Hungary; shift to lower cost areas like Manaus, Brazil and Reynosa, Mexico; and reduce manufacturing in Beijing and Dongguan, China. Also, CEO Satya Nadella gave hints about how Microsoft will make money on Nokia during Tuesday' conference call. Devices, he said, "go beyond" hardware and are about productivity. "I can take my Office Lens App, use the camera on the phone, take a picture of anything, and have it automatically OCR recognized and into OneNote in searchable fashion. There is a lot we can do with phones by broadly thinking about productivity." In other words, the sale of a smartphone is a means to other sales.

How Bird Flocks Resemble Liquid Helium

14 hours 56 min ago
sciencehabit (1205606) writes "A flock of starlings flies as one, a spectacular display in which each bird flits about as if in a well-choreographed dance. Everyone seems to know exactly when and where to turn. Now, for the first time, researchers have measured how that knowledge moves through the flock—a behavior that mirrors certain quantum phenomena of liquid helium. Some of the more interesting findings: Tracking data showed that the message for a flock to turn started from a handful of birds and swept through the flock at a constant speed between 20 and 40 meters per second. That means that for a group of 400 birds, it takes just a little more than a half-second for the whole flock to turn."

Popular Android Apps Full of Bugs: Researchers Blame Recycling of Code

Sun, 07/27/2014 - 7:55pm
New submitter Brett W (3715683) writes The security researchers that first published the 'Heartbleed' vulnerabilities in OpenSSL have spent the last few months auditing the Top 50 downloaded Android apps for vulnerabilities and have found issues with at least half of them. Many send user data to ad networks without consent, potentially without the publisher or even the app developer being aware of it. Quite a few also send private data across the network in plain text. The full study is due out later this week.

Newly Discovered Virus Widespread in Human Gut

Sun, 07/27/2014 - 4:35pm
A newly discovered virus has been found by a San Diego State University team to live inside more than half of all human gut cells sampled. Exploring genetic material found in intestinal samples, the international team uncovered the CrAssphage virus. They say the virus could influence the behaviour of some of the most common bacteria in our gut. Researchers say the virus has the genetic fingerprint of a bacteriophage - a type of virus known to infect bacteria. Phages may work to control the behaviour of bacteria they infect - some make it easier for bacteria to inhabit in their environments while others allow bacteria to become more potent. [Study lead Dr. Robert] Edwards said: "In some way phages are like wolves in the wild, surrounded by hares and deer. "They are critical components of our gut ecosystems, helping control the growth of bacterial populations and allowing a diversity of species." According to the team, CrAssphage infects one of the most common types of bacteria in our guts. National Geographic gives some idea why a virus so common in our gut should have evaded discovery for so long, but at least CrAssphage finally has a Wikipedia page of its own.

Off the Florida Coast, Astronauts Train For Asteroid Mission

Sun, 07/27/2014 - 3:06pm
Space.com gives an overview of the training that four astronauts are undergoing over 9 days submerged off the coast of Florida near Key Largo. The training mission, dubbed NEEMO 18, is one step toward a proposed (mid-2020s) mission to actually visit a captured asteroid in lunar orbit. In addition to the complications of working outside their school-bus sized habitat while awkwardly suited up in a low-gravity (or at least high buoyancy) environment, their mission also includes a 10-minute communications delay, to simulate the high-latency communications with mission control that would be inevitable for an actual asteroid mission. The experiments astronauts are doing during the mission, which began Monday (July 21), range from the physical to the behavioral. For example, each of the crew members sports a sensor that records how close the crew members work with each other inside the school-bus-size habitat. ... Communications with NEEMO Mission Control is usually constant, and there is the ability to send items to and from the habitat as needed. Also living inside the habitat are two support staff who are assisting with Aquarius maintenance and systems, as required. The crew members also have Internet and phone service to talk with family and friends.

Valencia Linux School Distro Saves 36 Million Euro

Sun, 07/27/2014 - 2:04pm
jrepin (667425) writes "The government of the autonomous region of Valencia (Spain) earlier this month made available the next version of Lliurex, a customisation of the Edubuntu Linux distribution. The distro is used on over 110,000 PCs in schools in the Valencia region, saving some 36 million euro over the past nine years, the government says." I'd lke to see more efforts like this in the U.S.; if mega school districts are paying for computers, I'd rather they at least support open source development as a consequence.

A Router-Based Dev Board That Isn't a Router

Sun, 07/27/2014 - 1:10pm
An anonymous reader writes with a link to an intriguing device highlighted at Hackaday (it's an Indiegogo project, too, if it excites you $90 worth, and seems well on its way to meeting its modest goal): The DPT Board is something that may be of interest to anyone looking to hack up a router for their own connected project or IoT implementation: hardware based on a fairly standard router, loaded up with OpenWRT, with a ton of I/O to connect to anything. It's called the DPT Board, and it's basically an hugely improved version of the off-the-shelf routers you can pick up through the usual channels. On board are 20 GPIOs, USB host, 16MB Flash, 64MB RAM, two Ethernet ports, on-board 802.11n and a USB host port. This small system on board is pre-installed with OpenWRT, making it relatively easy to connect this small router-like device to LED strips, sensors, or whatever other project you have in mind.

Satellite Images Show Russians Shelling Ukraine

Sun, 07/27/2014 - 12:05pm
U.S. officials today made public satellite imagery which they say proves that Russian forces have been shelling eastern Ukraine in a campaign to assist rebel groups fighting Ukraine’s government. The U.S. Office of the Director of National Intelligence, which released the civilian-taken satellite images Sunday, said they show visual evidence that Russia has been firing shells across the border at Ukrainian military forces. Officials also said the images show that Russia-backed separatists have used heavy artillery, provided by Russia, in attacks on Ukrainian forces from inside Ukraine. One image dated July 25/26 shows what DNI claims is “ground scarring” on the Russian side of the border from artillery aimed at Ukrainian military units in Ukraine, as well as the resultant ground craters on the Ukrainian side of the border:
