Giving Up Alternating Current - An anonymous reader writes: Yesterday we discussed Soylent, the artificial food substitute created by Rob Rhinehart and his team. As it turns out, this isn't Rhinehart's only unusual sustainability project. In a new post, he explains how he gave up on alternating current — a tough proposition for anyone living in the U.S. and still interested in using all sorts of modern technology. Rhinehart says, "Most power in the US is generated by burning coal, immediately squandering 67% of its energy, then run through a steam turbine, losing another 50%, then sent across transmission lines, losing another 5%, then to charge a DC device like a cell phone another 50% is lost in conversion. This means for 100 watts of coal or oil burned my phone gets a mere 16." The biggest hindrance was the kitchen. As you might expect for the creator of Soylent, he doesn't cook, and was able to get rid of almost all kitchen appliances because of that. He uses a butane stove for hot beverages. He powers a small computer off batteries, which get their energy from solar panels. For intensive tasks, he remotes to more powerful machines. He re-wired his apartment's LED lighting to run off direct current. Have any of you made similar changes? How much of an effect does this really have?

Epson Is Trying To Kill the Printer Ink Cartridge - An anonymous reader writes: Inkjet printer cartridges have been the bane of many small businesses and home offices for decades. It's interesting, then, that Epson is trying something new: next month, they're launching a new line of printers that come with small tanks of ink, instead of cartridges. The tanks will be refilled using bottles of ink. They're reversing the economics, here: the printer itself will be more expensive, but the refills will be much cheaper. Early reports claim you'll be spending a tenth as much on ink as you were before, but we'll see how that shakes out. The Bloomberg article makes a good point: it's never been easier to not print things. The printer industry needs to innovate if it wants us to keep churning out printed documents, and this may be the first big step.

FAA Has Approved More Than 1,000 Drone Exemptions - coondoggie writes: The Federal Aviation Administration today said it has issued 1,008 exemptions to businesses wanting to fly unmanned aircraft in the national airspace. Such small drones have been on the bad side of the news in the past few days: there have been at least three complaints about the diminutive aircraft flying near the flight path of JFK airport in New York. All three of the flights landed safely but the events prompted New York Senator Charles Schumer to call for "tougher FAA rules on drones," as well as geofencing software that could prohibit a done from flying higher than 500 feet, and keep it two miles away from any airport or sensitive area.

Hackers Exploit Adobe Flash Vulnerability In Yahoo Ads - vivaoporto notes a report that a group of hackers have used online ad networks to distribute malware over several of Yahoo's websites. The attack began on Tuesday, July 28, and was shut down on Monday, August 3. It was targeted at Yahoo's sports, finance, gaming, and news-related sites. Security firm Malwarebytes says the hackers exploited a Flash vulnerability to redirect users to the Angler Exploit Kit. "Attacks on advertising networks have been on the rise ... researchers say. Hackers are able to use the advertising networks themselves, built for targeting specific demographics of Internet users, to find vulnerable machines. While Yahoo acknowledged the attack, the company said that it was not nearly as big as Malwarebytes had portrayed it to be."

Facebook Allows Turkish Government To Set the Censorship Rules - New submitter feylikurds writes: Facebook has been blocking and banning users for posting Kurdish or anti-Turkish material. Many screenshots exists of Facebook notifying people for such. You can insult any single historical figure that you like on Facebook except one: Turkey's founder Mustafa Kemal 'Ataturk'. However, he should not receive special treatment and be protected from criticism, but rather should be treated and examined like everyone else. In order to be accessible within Turkey, Facebook has allowed the repressive Turkish government to set the censorship rules for billions of their users all around the globe. Facebook censors Kurds on behalf of Turkey. To show the world how unjust this policy is, this group discusses Facebook's censorship policy as it relates to Kurds (Facebook account required) and how to get Facebook to change its unfair and discriminatory policy. Makes re-reading Hossein Derakhshan's piece worth the time.

Cleaning Up Botnets Takes Years, May Never Be Completed - Once a botnet has taken root in a large pool of computers, truly expunging it from them may be a forlorn hope. That, writes itwbennett, is: the finding of researchers in the Netherlands who analyzed the efforts of the Conficker Working Group to stop the botnet and find its creators. Seven years later, there are still about 1 million computers around the world infected with the Conficker malware despite the years-long cleanup effort. 'These people that remain infected — they might remain infected forever,' said Hadi Asghari, assistant professor at Delft University of Technology in the Netherlands. The research paper will be presented next week at the 24th USENIX Security Symposium in Washington, D.C. (And "Post-Mortem of a Zombie" is an exciting way to title a paper.)

Toshiba, SanDisk Piloting 3D NAND That Doubles Previous Capacity - Lucas123 writes: Under a joint development agreement, Toshiba and SanDisk have begun pilot production of a new 48-layer 256Gb NAND flash chip in a brand new fab in Mie prefecture, Japan. The new X3 chips, which double capacity from 16GB to 32GB over the previous product, are made with triple-level cell (TLC) flash compared with Toshiba's last multi-level cell (MLC) chip, which stored two-bits per transistor. The chips are expected to begin shipping in products next year. The companies plan to use the new memory in a wide number of products, including consumer SSDs, smartphones, tablets, memory cards, and enterprise SSDs for data centers, the companies said.

Behind the Microsoft Write-Off of Nokia - UnknowingFool writes: Previously Microsoft announced they had written off the Nokia purchase for $7.6B in the last quarter. In doing so, Microsoft would create only the third unprofitable quarter in the company's history. Released on July 31, new financial documents detail some of the reasoning and financials behind this decision. At the core of the problem was that the Phone Hardware business was only worth $116M, after adjusting for costs and market factors. One of those factors was poor sales of Nokia handhelds in 2015. Financially it made more sense to write it all off.

NTT, Japan's Largest Fixed Telecom Provider, Begins Phasing Out ADSL - AmiMoJo writes: Nippon Telegraph and Telephone Corporation (NTT), the third largest telecoms provider in the world, is beginning to phase out ADSL for broadband internet access (Google Translate helps). NTT is no longer accepting new registrations, and no longer manufacturing the equipment required. Instead they recommend users opt for their FLET'S HIKARI fibre optic service. Their "Giga Mansion Smart Type" services offers 1Gb/sec for around $40/month.

Philadelphia Hackers and Others Offer Brotherly Love To Fallen Robot - An anonymous reader writes: Since a hitchhiking robot was destroyed in Philadelphia over the weekend, there has been an overwhelming show of support according to its co-creators Frauke Zeller and David Smith. Makers from all over Philly have reached out and offered to help rebuild the robot. "We'll say that at this moment, if we get the OK from the creators to repair or replace the needed parts for HitchBOT, we'll be happy to do so," wrote Georgia Guthrie, executive director for a local makerspace called The Hacktory. "If not, we understand and we may just build ourselves a HitchBot2 to send along on its journey. We feel it's the least we can do to let everyone, especially the Robot community, know that Philly isn't so bad."

Houston Firm NanoRacks To Take Chinese Experiment To International Space Station - MarkWhittington writes: The Houston Chronicle's Eric Berger reports that for the first time a Chinese experiment will fly on the International Space Station, thanks to an arrangement between a research group based at the Beijing Institute of Technology and a private firm in Houston called NanoRacks. The deal seems to have been designed to avoid the prohibition against space cooperation between the Chinese regime and NASA, since the space agency is not directly involved. The experiment, which involves the effects that space radiation has on DNA, will be carried to the ISS by another private firm, SpaceX. Presumably the experiment would be run by a non NASA crew member to avoid any direct involvement with the space agency.

Researchers: The Thermostat In Your Office May Be Sexist - sciencehabit writes: If you're constantly bundling up against your office building's air conditioning, blame Povl Ole Fanger. In the 1960s, this Danish scientist developed a model, still used in many office buildings around the world, which predicts comfortable indoor temperatures for the average worker. The problem? The average office worker in the 1960s was a 40-year-old man sporting a three-piece suit. But fear not, those for whom the 'work sweater' has become a mandatory addition to office attire: Researchers say they have built a better model.

Fuel Cells Promise To Reduce Carbon Emissions of Mobile Base Stations - Mickeycaskill writes: Vodafone says fuel cells could reduce the carbon emissions and noise pollution caused by mobile base stations in remote areas of developing economies. The company has 122 million mobile data customers in emerging markets and needs to expand its network in these countries to meet demand. However many base stations are in rural areas where grid power is unreliable and need on-site power generation. These are typically diesel powered, but Vodafone wants to move away from this type of power and says solar power is too expensive and not suitable for urban areas. It has already deployed 200 fuel cells in South Africa and wants to replicate the model elsewhere.
