Michigan Latest State To Ban Direct Tesla Sales

Lucas123 So much for a free market (177 comments)

These outdated statues were originally designed to protect little dealerships from the threat of big auto opening their own dealerships if one of their indirect dealers refused to carry their lemons. So dealers under pressure from Detroit were forced to sell the crappy next to the good cars.

Today, prohibiting direct sales protects only the dealerships and harms the consumer. There’s no reason to prohibit a consumer from buying directly from the manufacturer.

The CDC Is Carefully Controlling How Scared You Are About Ebola

Lucas123 Perhaps I'm naive... (478 comments)

It seems to me the best way (every time) to alleviate fear is by spreading truth. The CDC should set itself the task of disseminating as much information about Ebola and how it's spread as possible.

Physicist Claims Black Holes Mathematically Don't Exist

Lucas123 That's not what she's saying (356 comments)

She's not saying the things are not "very very dense" rather just that they never collapse further than the state that gravity can overcome the speed of light. I believe she's saying a black hole's mass would be "evenly" (or not) spread out over the volume encompassed by the event horizon, rather than in a singularity.

Science Has a Sexual Assault Problem

Lucas123 Then it happens less in science than in general (460 comments)

The study the level of sexual assault of trainees in academic fieldwork environments... was 26% of women and 6% of men reported experiencing sexual assault. According to a study by the CDC, 51.9 percent of surveyed women and 66.4 percent of surveyed men said they were physically assaulted as a child by an adult caretaker and/or as an adult by any type of attacker. More than half (54 percent) of the female rape victims identified by the survey were younger than age 18 when they experienced their first attempted or completed rape. Violence against women is primarily intimate partner violence: 64.0 percent of the women who reported being raped, physically assaulted, and/or stalked since age 18 were victimized by a current or former husband, cohabiting partner, boyfriend, or date. In comparison, only 16.2 percent of the men who reported being raped and/or physically assaulted since age 18 were victimized by such a perpetrator. Study: https://www.ncjrs.gov/pdffiles...

New Study Projects World Population of 11B by 2100

Lucas123 Familiar story line (326 comments)

The Stardate is 5423.4. The Federation starship Enterprise arrives at the planet Gideon to begin diplomatic relations and invite the inhabitants to join the Federation. Gideon is reported to be a virtual paradise where the people live incredibly long lives in a nearly germ-free environment, but they refuse to allow anyone but Captain James Kirk from the Enterprise, to beam down. Upon beaming down, however, Kirk learns that the population has exploded to the point where the planet can barely contain the populace. Gideon's leaders plan is to infect the people with a human virus in an attempt to "control" the overpopulation problem caused by the people's long lifespans in a germ-free environment. So, as I see it, the problem is easily solved. Find a alien with a virus for which we have no cure.

Artificial Pancreas Shows Promise In Diabetes Test

Lucas123 Warning: Snarky comment (75 comments)

Over the past four decades, we've seen squat in the form of treatment for diabetes other than improving the delivery of insulin delivery for diabetics, which has been around since the 1920s. Honestly, it almost seems as if the insulin market is just too lucrative to allow a real cure for Type 1 diabetes. We march on continuing to watch little children struggle with this disease through adulthood and often succumb to an early death because of it. C'mon scientific community. Get your collective heads our of your arses and curse this.

So no more end-of-the-month speed traps by police departments to balance their budgets? Whatever will our police departments do for money? Reminds me of the outcry when The National Maximum Speed Law was eventually disregarded by almost every state and they raised their respective speed limits back up to 65mph on most highways -- because lowering it to 55mph did nothing to reduce accidents. Oh, the funds staties lost.

U.K. Supermarkets Beta Test Full-Body 3D Scanners for Selfie Figurines

Lucas123 Lucas123 writes  |  yesterday

Lucas123 (935744) writes "Walmart-owned ASDA supermarkets in the UK. are beta testing 3D full-body scanning booths that allow patrons to buy 6-in to 9-in high "selfie" figurines. Artec Group, a maker of 3D scanners and software, said its Shapify Booth, which can scan your entire body in 12 seconds and use the resulting file to create a full-color 3D printed model, is making its U.S. debut this week. The 3D Shapify booths are equipped with four wide view, high-resolution scanners, which rotate around the person to scan every angle. Artec claims the high-powered scan and precision printing is able to capture even the smallest details, down to the wrinkles on clothes. The scanning process generates 700 captured surfaces, which are automatically stitched together to produce an electronic file ready for 3D printing. Artec offers to print the figurines for booth operators (retailers) for $50 for a 6-in model, $70 for a 7.5-in model, and $100 for a 9-in figurine."

Samsung admits to software bug on 840 EVO SSDs

Lucas123 Lucas123 writes  |  2 days ago

Lucas123 (935744) writes "Samsung has issued a firmware fix for a bug on its popular 840 EVO triple-level cell SSD. The bug apparently slows read performance tremendously for any data more than a month old that has not been moved around on the NAND. The 840 EVO is one of the companies most affordable SSDs, as it retails for under 50 cents a gig. Samsung said in a statement that the read problems occurred on its 2.5-in 840 EVO SSDs and 840 EVO mSATA drives because of an error in the flash management software algorithm. Some users on technical blog sites, such as Overclock.net, say the problem extends beyond the EVO line. They also questioned whether the firmware upgrade was a true fix or just covers up the bug by simply moving data around the SSD."

Ethernet is coming to cars

Lucas123 Lucas123 writes  |  2 days ago

Lucas123 (935744) writes "Automobile industry support for Ethernet as an interconnect specification for all electronics in the car and for the car to connect to the Internet outside the car is growing quickly. Additionally, one of the largest suppliers of silicon to the industry — Freescale — today announced its first automotive-grade Ethernet modules. The 100Mbps modules will offer up to four separate video ports and can connect together instrument clusters, infotainment systems and telematics all on the same ring topology. Driving Ethernet adoption in vehicles are trends such as such as federally mandated backup cameras, lane-departure warning systems, traffic light recognition and collision avoidance sensors, and in-vehicle WiFi as well as streaming video on embedded displays. While Freescale's not the first to offer an automotive-grade Ethernet chipset, it is the largest supplier to date. By 2020, many cars will have 50 to 60 Ethernet ports and even entry-level vehicles will have 10, according to a study by research firm Frost & Sullivan. (Premium vehicles will likely have more than 100 Ethernet nodes by then.)"

Tesla teardown reveals driver-facing electronics built by iPhone 6 suppliers

Lucas123 Lucas123 writes  |  5 days ago

Lucas123 (935744) writes "There's a lot to like about the Tesla Model S. It's an EV that can go from from 0 to 60 mph (96 km/h) in 4.2 seconds and can travel 265 miles on a single charge. But, a tear down of the vehicle by IHS Technology has also revealed that Elon Musk avoided third-party design and build routes used traditionally by auto makers and spared no expense on the instrument cluster and infotainment (head unit) system, which is powered by two 3, 1.4Ghz, quad-core NVIDIA Tegra processors. IHS called the Tesla's head unit the most sophisticated it's ever seen, with 1,000 more components than any it has previously analyzed. A bill of materials (BOM) for the virtual instrument cluster and the premium media control unit is also roughly twice the cost of the highest-end infotainment unit examined by IHS. Andrew Rassweiler, senior director for materials and cost benchmarking at IHS, said the use of large displays in the cabin, the touch-screen-based controls, and the mobile microchips make "the Tesla experience more like a media tablet or high-end smartphone than a traditional automobile.""

Tiny Wireless Device Offers Tor Anonymity

Lucas123 Lucas123 writes  |  about two weeks ago

Lucas123 (935744) writes "The Anonabox router project, currently being funded through a Kickstarter campaign, has surpassed its original $7,000 crowdfunding goal by more than 10 times in just one day. The open source router device connects via Wi-Fi or an Ethernet cable making it harder for your IP address to be seen. While there have been other Tor-enabled routers in the past, they aren't small enough to fit in a shirt pocket like the Anonabox and they haven't offered data encryption on top of the routing network. The device, which is being pitched as a way for consumers to securely surf the web and share content (or allow businesses to do the same), is also being directed at journalists who may want to share stories in places where they might otherwise be censored."

Are eHealth Records Responsible for Docs Missing Ebola Diagnosis?

Lucas123 Lucas123 writes  |  about two weeks ago

Lucas123 (935744) writes "Thomas Eric Duncan died this morning at Texas Health Presbyterian Hospital Dallas. Duncan had first visited Presbyterian's ER on Sept. 23 with fever, headache and stomach pain, and even though he told a nurse he'd just returned from Liberia, he was sent home. Five days later, Duncan returned via ambulance. Initially, the hospital reported that a flaw in its eHealth records system was responsible for physicians misdiagnosing Duncan. A day later, it retracted that statement. Experts, however, say instead of improving work flow, electronic health records (EHRs) often eat healthcare worker time and distract physicians from patients, creating cognitive dissonance that leads to mistakes. Errors in patient care due to EHRs are "incredibly common," according to a report released last year by the American College of Physicians. Hospitals that are under EHR vendor contracts, however, can prevent physicians from speaking publicly about those problems by using gag clauses. Dr. Randall Case, an emergency room physician and data infomatics expert who has worked for EHR makers such as Cerner and Siemens, said the problem with EHRs is multifaceted. The systems are "thrust" on physicians and nurses, who sometimes receive minimal training and then must adapt their workflows around them. While workflows, user interfaces and the learnability of their systems have improved, the improvements have been marginal, he said."

Solar Could Lead In Power Production By 2050

Lucas123 Lucas123 writes  |  about three weeks ago

Lucas123 (935744) writes "Solar power could be the leading source of electricity compared with other renewables and conventional sources of power, such as oil and coal, according to a pair of reports from International Energy Agency. PV panels could produce 16% of the world's electricity, while solar thermal electricity (STE) is on track to produce 11%. At the end of 2013, there had been 137GW of solar capacity deployed around the world. Each day, an additional 100MW of power is deployed. One reason solar is so promising are plummeting prices for photovoltaic cells and new technologies that promise greater solar panel efficiency. For example, MIT just published a report on a new a material that could be ideal for converting solar energy into heat by tuning the material's spectrum of absorption. Ohio State University just announced what it's referring to as the world's first solar battery, which integrates PV with storage at a microsopic level. "We've integrated both functions into one device. Any time you can do that, you reduce cost," said iying Wu, a professor of chemistry and biochemistry at Ohio State."

Mercedes-Benz Reveals Self-Driving Semi-Trailer Truck

Lucas123 Lucas123 writes  |  about three weeks ago

Lucas123 (935744) writes "Mercedes-Benz displayed an 18-wheel semi-trailer truck that can drive itself on highways. The Mercedes-Benz Future Truck 2025 was demonstrated at the 2014 International Commercial Vehicle show this month. Like other self-driving vehicles, the truck uses sensors and exterior cameras to stay within lanes and detect objects around it in order to adjust speed. The inside of the truck's cab looks like a lounge. The driver's seat rotates 45 degrees to allow autonomous driving away from the steering wheel, and instead of the speedometer and tachometer digital displays, monitors and tablets are placed in the cockpit. Because acceleration and braking is optimized, creating a constant flow of traffic, gas consumption and emissions of the Future Truck 2025 can be reduced, the company said. Transport times are also predictable."

3D Printer Able to Produce Skin w/Hair Follicles and Sweat Glands

Lucas123 Lucas123 writes  |  about three weeks ago

Lucas123 (935744) writes "A 3D printer developed by researchers at the University of Toronto is capable of using a patient's own cells to print skin. The technology could be used to treat burn victims and patients with other types of injuries, as well as to test pharmaceutical drugs. While still in pilot mode, the new PrintAlive Bioprinter is in the process of being commercialized by MaRS Innovations in collaboration with the Innovations and Partnerships Office (IPO) of the University of Toronto, whose labs have filed two patents on the device. The 3D skin printer works by placing the patient's cells along with other biomaterials into a micro-device, which then pushes them out through several channels. The biomaterials are then mixed, causing a chemical reaction that forms a "mosaic hydrogel", a sheet-like substance compatible with the growth of cells into living tissues. The hydrogel allows the various dermis cells to be seeded in precise and controlled patterns. The resulting thin film is then rolled up to crease thicker layers of tissue."

Utilities Should Worry. Rooftop Solar Could Soon Cut Their Profit

Lucas123 Lucas123 writes  |  about a month ago

Lucas123 (935744) writes "A study by the Lawrence Berkeley National Laboratory predicts that distributed rooftop solar panel installations will grow from 0.2% market penetration today to 10% by 2022, during which time they're likely to cut utility profits from 8% to 41%. Using those same metrics, electricity rates for utility customers will grow only by as much as 2.7% over the next eight years. By comparison, the cost of electricity on average rose 3.1% from 2013 to 2014. The study was performed for the Office of Energy Efficiency and Renewable Energy under the U.S. Department of Energy. One of the main purposes of the study was to evaluate measures that could be pursued by utilities and regulators to reduce the financial impacts of distributed photovoltaics."

"The surprising (and bad) news is that Seagate 3TB drives are failing a lot more, with their failure rate jumping from 9% to 15%. The Western Digital 3TB drives have also failed more, with their rate going up from 4% to 7%,” the company's blog states. For example, Seagate’s Barracuda 7200.14 3TB hard drives with an average 1.9 year lifespan had a 15.7% annual failure rate. As with previous studies from Backblaze, the study also showed consumer drives are more reliable than enterprise drives."

Why the iPhone 6 Maintained the Same Base Memory as the iPhone 5

Lucas123 Lucas123 writes  |  about a month ago

Lucas123 (935744) writes "When the iPhone 5 was launched two years ago, the base $199 (with wireless plan) model came with 16GB of flash memory. Fast forward to this week when the iPhone 6 was launched with the same capacity. Now consider that the cost of 16GB of NAND flash has dropped by more than 13% over the past two years. So why would Apple increase capacity on its $299 model iPhone 6 to 64GB (eliminating the 32GB model), but but keep the 16GB in the $199 model? The answer may lie in the fact that the 16GB iPhone is, and has been, by far the best selling model. IHS analyst Fang Zhang believes Apple is using that to push users to its iCloud storage service. Others believe restricting storage capacity allows Apple to afford the new features, like NFC and biometrics."

Once vehicles are connected to the Internet of Things, who guards your privacy?

Lucas123 Lucas123 writes  |  about a month ago

Lucas123 (935744) writes "Carmakers already remotely collect data from their vehicles, unbeknownst to most drivers, but once connected via in-car routers or mobile devices to the Internet, and to roadway infrastructure and other vehicles around them, that information would be accessible by the government or other undesired entities. Location data, which is routinely collected by GPS providers and makers of telematics systems, is among the most sensitive pieces of information that can be collected, according to Nate Cardozo, an attorney with the Electronic Frontier Foundation. "Not having knowledge that a third party is collecting that data on us and with whom they are sharing that data with is extremely troubling," Cardozo said. in-vehicle diagnostics data could also be used by government agencies to track driver behavior. Nightmare scenarios could include traffic violations being issued without law enforcement officers on the scene or federal agencies having the ability to track your every move in a car."

Micron Releases 16nm Process SSDs With Dynamic Flash Programming

Lucas123 Lucas123 writes  |  about a month ago

Lucas123 (935744) writes "Micron's newest client flash drive line, the M600, uses its first 16nm process technology and dynamic write acceleration firmware that allows the flash to be programmed as SLC or MLC instead of using overprovisioning or reserving a permanent pool of flash cache to accelerate writes. The ability to dynamically program the flash reduces power use and improves write performance as much as 2.8 times over models without the feature, according to Jon Tanguy, Micron's senior technical marketing engineer. The new lithography process technology also allowed Micron to reduce the price of the flash drive to 45 cents a gigabyte, meaning a 1TB 2.5-in SATA SSD now retails for $450."
