To Really Cut Emissions, We Need Electric Buses, Not Just Electric Cars

Slashdot.org - Tue, 09/09/2014 - 19:14
An anonymous reader writes: All the EV attention these days is going to Tesla and other sedan manufacturers, but this article makes the case that it's far more important to switch our buses over to electric power than our cars. "Last year, according to the American Public Transportation Association, buses hauled 5.36 billion passengers. While usage has fallen in recent years, thanks in part to the growth of light rail and subway systems, buses still account for more rides each year than heavy rail, light rail, and commuter rail combined—and for about half of all public transit trips." This, while managing around 4-5 miles per gallon of gas, and public buses usually average about 50,000 miles per year. The electric buses themselves are significantly more expensive, but the difference is made up dramatically lower fuel costs. And there will be difficulties: "The range—up to 30 miles—limits Proterra buses to certain routes, so it's hard for an agency to go all in. Drivers have to be trained to brake and accelerate differently, and to maneuver into the docking stations. And Doran Barnes of Foothill Transit notes that some of the cost advantage of using electricity instead of diesel can dissipate. Electric cars can be charged at night, when power prices are low. But buses have no choice but to recharge in the middle of the day, when utilities often impose higher peak usage rates."

Report: Microsoft To Buy Minecraft Studio For $2bn+

Slashdot.org - Tue, 09/09/2014 - 18:37
dotarray (1747900) writes "A surprising story has emerged today that suggests Microsoft is looking to buy Minecraft developer Mojang. The reported price tag is "more than US$2 billion." The original report is at the WSJ (possibly behind a paywall). Quoting: "For Microsoft, "Minecraft" could reinvigorate the company's 13-year-old Xbox videogame business by giving it a cult hit with a legion of young fans. Mojang has sold more than 50 million copies of "Minecraft" since it was initially released in 2009 and earned more than $100 million in profits last year from the game and merchandise. "Minecraft" is already available on the Xbox, as well as Sony Corp.'s PlayStation, PCs and smartphones."

WD Announces 8TB, 10TB Helium Hard Drives

Slashdot.org - Tue, 09/09/2014 - 17:51
Lucas123 writes: Western Digital's HGST subsidiary today announced it's shipping its first 8TB and the world's first 10TB helium-filled hard drive. The 3.5-in, 10TB drive also marks HGST's first foray into the use of singled magnetic recording technology, which Seagate began using last year. Unlike standard perpendicular magnetic recording (PMR), where data tracks rest side by side, SMR overlaps the tracks on a platter like shingles on a roof, thereby allowing a higher areal density. Seagate has said SMR technology will allow it to achieve 20TB drives by 2020. That company has yet to use helium, however. HGST said its use of hermetically-sealed helium drives reduces friction among moving drive components and keeps dust out. Both drives use a 7-platter configuration with a 7200 RPM spindle speed. The company said it plans to discontinue its production of air-only drives by 2017, replacing all data center models with helium drives.

WSJ: Microsoft to buy Minecraft maker Mojang

OSNews.com - Tue, 09/09/2014 - 17:21
Well, file this under 'holy crap'. Microsoft is nearing a deal to buy Mojang AB, makers of the Minecraft video game franchise, according to a new report. According to the Wall Street Journal, the deal would value Mojang at more than $2 billion and could be signed as soon as this week. No. Just no.

Device Boots Drones, Google Glass Off Wi-Fi

Slashdot.org - Tue, 09/09/2014 - 17:08
An anonymous reader writes: Amid the backlash against spy-eye drones as well as wearable cameras like Google Glass, one company is building a device to fight back. The Cyborg Unplug actively scans for drones or Google Glass on a local wireless network and blocks their traffic. They're billing it as an "anti-surveillance system" and marketing it toward businesses, restaurants, and schools. They take pains to note that it's not a jammer, instead sending copies of a de-authentication packet usually sent by a router when it disconnects a device. The device can, however, force devices to disconnect from any network, which they warn may be illegal in some places.

3 Short Walking Breaks Can Reverse Harm From 3 Hours of Sitting

Slashdot.org - Tue, 09/09/2014 - 16:27
An anonymous reader writes: Medical researchers have been steadily building evidence that prolonged sitting is awful for your health. One major problem is that blood can pool in the legs of a seated person, causing arteries to start losing their ability to control the rate of blood flow. A new experimental study (abstract) has discovered it's quite easy to negate these detrimental health effects: all you need to do is take a leisurely, 5-minute walk for every hour you sit. "The researchers were able to demonstrate that during a three-hour period, the flow-mediated dilation, or the expansion of the arteries as a result of increased blood flow, of the main artery in the legs was impaired by as much as 50 percent after just one hour. The study participants who walked for five minutes for each hour of sitting saw their arterial function stay the same — it did not drop throughout the three-hour period. Thosar says it is likely that the increase in muscle activity and blood flow accounts for this."
