Make Magazine weighs in on an issue that's suddenly relevant in a world where less than $10 can buy a new, (nominally) complete computer. Which one makes most sense? Both the $9 C.H.I.P and the newest, stripped-down Raspberry Pi model have pluses and minuses, but to make either one actually useful takes some additional hardware; at their low prices, it's not surprising that neither one comes with so much as a case. The two make different trade-offs, despite being just a few dollars apart in ticket price. C.H.I.P. comes with built-in storage that rPi lacks, for instance, but the newest Pi, like its forebears, has built in HDMI output. Make's upshot? The cost of owning either a C.H.I.P. or a Pi is a bit more money than the retail cost of the boards. Peripherals such as a power cable, keyboard, mouse, and monitor are necessary to accomplish any computer task on either of the devices. But it turns out the $5 Raspberry Pi Zero costs significantly more to operate than the Next Thing Co. C.H.I.P.

DeviceGuru writes: LinuxGizmos and Linux.com have just launched their annual 2-minute survey asking folks to rate their favorite hacker SBCs from a list of 53 single board computers that are priced below $200, supported by open documentation and Linux or Android OSes, and will ship before July. As usual, the survey's data will be made available publicly, but one big change this year is that participants can register for a random drawing that will give away 20 hacker SBCs, split equally among the BeagleBone Black, Imagination Creator CI20, Intel Edison Kit for Arduino, and Qualcomm DragonBoard 410c. (Emails submitted will only be used for selecting and notifying SBC drawing winners, say the sites.)

Zothecula writes: Until the 1960s, Japan's three I-400-class subs were the largest submarines ever built. They were so large, in fact, that they could each carry and launch three Aichi M6A Seiran amphibious aircraft. The idea was that the submarines could stealthily bring the planes to within striking distance of US coastal cities, where they could then take off and conduct bombing runs. Now, for the first time since it was scuttled at the end of World War II, one of the sunken subs' aircraft hangars has been photographed. The M6A on display at the Air and Space Museum's Udvar-Hazy Center is worth seeing, if you get a chance.

HughPickens.com writes Paul Tassi reports at Forbes that the first four episodes of the new season of "Game of Thrones", nearly half of the ten total episodes, have been leaked online to various torrent sites. The four episodes appeared to come from a screener sent to reviewers with the digital watermark blurred out and are in 480p video format, equivalent to standard-definition TV, not HD.The episodes have already been downloaded almost 800,000 times, and that figure was expected to blow past a million downloads by the season 5 premiere. Game of Thrones has consistently set records for piracy, which has almost been a point of pride for HBO. "Our experience is [piracy] leads to more penetration, more paying subs, more health for HBO, less reliance on having to do paid advertising If you go around the world, I think you're right, Game of Thrones is the most pirated show in the world. Well, you know, that's better than an Emmy."

How the leak happened isn't a mystery. Television critics typically receive the first four episodes of an HBO show before its season premiere, and "Game of Thrones" is no exception. HBO could not immediately say whether the leak could be traced to screener copies of the show. "I suspect HBO may be a bit more restrictive about handing out Game of Thrones screeners to press, given the event-like nature of the show and its reliance on keeping spoilers close to the chest," writes Tassi. "I really don't see why commentary like that needs to exist in the first place." The network can take solace in at least one thing, though. Episode four ends on a heck of a cliffhanger, and those who pirated the episodes will be in the same boat as those of us who received them legally — waiting until May to find out what happens next. "I would imagine it's more fun to just spend the next month watching week to week as nature intended, even if you are watching illegally," concludes Tassi. "Game of Thrones is one of the last true "event" shows where it's something you want to talk about Sunday night or Monday morning with friends and strangers alike."

Rocky Mountain Unmanned Systems seems to be primarily in the business of selling aerial 'copter drones ranging in price from sub-$100 up into $1000s. But there they were at the 2015 CES (Consumer Electronics Show), showing off a submarine drone and a wheeled drone. These products don't seem to be on the company's website or even on their Facebook page quite yet. Jon McBride, the person manning their CES booth, told Timothy these products would be around soon, as in February. But it looks like a bit of extra patience is in order, although you can contact Jon through the company's Facebook page (his suggestion) if you have an urgent need for an underwater or wheeled drone for your business or government agency -- or even just for fun.

An anonymous reader writes: The United States spends $1.8 billion to build a brand new, state of the art, Virginia-class nuclear powered attack submarine. They are the backbone of the U.S. Navy and the ultimate threat to those nations who are building massive amounts of missiles to keep U.S. naval forces like aircraft carriers away from their shores — think China, Russia, Iran and various others. Sadly, the era of the submarine could be coming to an end. New types of detection technology could make the stealth capabilities of subs obsolete, just like the age of flight made the battleship into a floating museum:

"The ability of submarines to hide through quieting alone will decrease as each successive decibel of noise reduction becomes more expensive and as new detection methods mature that rely on phenomena other than sounds emanating from a submarine. These techniques include lower frequency active sonar and non-acoustic methods that detect submarine wakes or (at short ranges) bounce laser or light-emitting diode (LED) light off a submarine hull. The physics behind most of these alternative techniques has been known for decades, but was not exploited because computer processors were too slow to run the detailed models needed to see small changes in the environment caused by a quiet submarine. Today, "big data" processing enables advanced navies to run sophisticated oceanographic models in real time to exploit these detection techniques. As they become more prevalent, they could make some coastal areas too hazardous for manned submarines."

This could force submarines to stay far away from areas where they could be found. Alternately, they could evolve into something different: underwater aircraft carriers hosting drones that could strike below the surface.

New submitter LOGINS SUC (713291) writes Truly in the first-world problems category, I've been looking for large format (>55") HD/UHD screens for home entertainment. In light of the recent Samsung big-brother monitoring and advertisement injection concerns, does any reputable manufacturer still make "stupid" TVs? I don't want to pay for all the WiFi, apps, cameras, or microphones. I don't need it to have speakers. And at this point, I don't even care if it has the TV receiver functionality. All this stuff leads to vendor lock-in or is well on the path to obsolescence by the time I purchase the device. I prefer all of this non-visual functionality be handled by devices better suited to the purpose and I don't want to pay for screens including these widgets I have no intention of ever using, at all.

I've searched all the normal retail outlets. If I find anything, they are wildly expensive. "Computer monitors" fit the bill but are almost all 55") LCDs in the sub-$3,000 range anymore? Are projectors the last bastion of visual purity for home entertainment?

Zothecula writes: Now that NASA has got the hang of planetary rovers, the space agency is looking at sending submarines into space around the year 2040. At the recent 2015 NASA Institute for Advanced Concepts Symposium, NASA scientists and engineers presented a study of the Titan Submarine Phase I Conceptual Design (PDF), which outlines a possible mission to Saturn's largest moon, Titan, where the unmanned submersible would explore the seas of liquid hydrocarbons at the Titanian poles.

"At its heart, the submarine would use a 1 kW radiothermal Stirling generator. This would not only provide power to propel the craft, but it would also keep the electronics from freezing. Unfortunately, Titan is so cold that it's almost a cryogenic environment, so the waste heat from the generator would cause the liquids around it to boil and this would need be taken into account when designing the sub to minimize interference. However, NASA estimates that the boat could do about one meter per second (3.6 km/h, 2.2 mph)."

DeviceGuru writes As seen in this year-end summary of 40 hacker-friendly SBCs, 2014 brought us plenty of new Linux and Android friendly single-board computers to tinker with — ranging from $35 bargains, to octa-core powerhouses. Many of the new arrivals feature 1-2GHz multicore SoCs, 1-2GB RAM, generous built-in flash, gigabit Ethernet, WiFi, on-board FPGAs, and other extras. However, most of the growth has been in the sub-$50 segment, where the Raspberry Pi and BeagleBone reign supreme, but are now being challenged by a growing number of feature-enhanced clones, such as the Banana Pi and Orange Pi. Best of all, there's every reason to expect 2015 to accelerate these trends.

This is a "wet" submarine. It doesn't try to keep water out. You wear SCUBA gear while pedaling it. And yes, it is powered by a person pushing pedals. That motion, through a drive train, makes manta-style wings flap. This explains the name, since rays are Batoids, and this sub is a fake Batoid, not a real one. It's a beautiful piece of work, and Martin Plazyk is obviously proud to show it off. He and his father, Bruce, operate as Faux Fish Technologies. Follow that link and you'll see many photos, along with a nice selection of videos showing their creations not just in static above-water displays, but in their natural (underwater) element. Meanwhile, here on Slashdot, Martin tells how Faux Fish subs are made. (Alternate Video Link)

MojoKid writes: For the past few years, Intel has promised that its various low-power Atom-based processors would usher in a wave of low-cost Android and Windows mobile products that could compete with ARM-based solutions. And for years, we've seen no more than a trickle of hardware, often with limited availability. Now, that's finally beginning to change. Intel's Bay Trail and Merrifield SoCs are starting to show up more in full-featured, sub-$200 devices from major brands. One of the most interesting questions for would-be x86 buyers in the Android tablet space is whether to go with a Merrifield or Bay Trail Atom-based device. Merrifield is a dual-core chip without Hyper-Threading. Bay Trail is a quad-core variant and a graphics engine derived from Intel's Ivy Bridge Core series CPUs. That GPU is the other significant difference between the two SoCs. With Bay Trail, Intel is still employing their own graphics solution, while Merrifield pairs a dual-core CPU with a PowerVR G6400 graphics core. So, what's the experience of using a tablet running Android on x86 like these days? Pretty much like using an ARM-based Android tablet currently, and surprisingly good for any tablet in the $199 or less bracket. In fact, some of the low cost Intel/Android solutions out there currently from the likes of Acer, Dell, Asus, and Lenovo, all compete performance-wise pretty well versus the current generation of mainstream ARM-based Android tablets.

jfruh writes While Windows-based tablets haven't exactly set the world on fire, Microsoft hasn't given up on them, and its hardware partners haven't either. HP has announced a series of Windows tablets, with the 7-inch low-end model, the Stream 7, priced at $99. The Stream brand is also being used for low-priced laptops intended to compete with Chromebooks (which HP also sells). All are running Intel chips and full Windows, not Windows RT.

KentuckyFC writes: Underwater vehicles have never matched the extraordinary agility of marine creatures. While many types of fish can travel at speeds of up to 10 body lengths per second, a nuclear sub can manage a less than half a body length per second. Now a team of researchers has copied a trick used by octopuses to build an underwater robot capable of matching the agility of marine creatures. This trick is the way an octopus expands the size of its head as it fills with water and then squirts it out to generate propulsion. The team copied this by building a robot with a flexible membrane that also expands as it fills with water.

The fluid then squirts out through a rear-facing nozzle as the membrane contracts. To the team's surprise, the robot reached speeds of 10 body lengths per second with a peak acceleration of 14 body lengths per second squared. That's unprecedented in an underwater vehicle of this kind. What's more, the peak force experienced by the robot was 30 per cent greater than the thrust generated by the jet. The team think they know why and say the new technique could be used to design bigger subs capable of even more impressive octopus-like feats.

An anonymous reader writes: Caffeine is a staple of most workplaces — it's rare to find an office without a coffee pot or a fridge full of soda. It's necessary (or at least feels like it's necessary) because many workers have a hard time staying awake while sitting at a desk for hours at a time, and the alternative — naps — aren't usually allowed. But new research shows it might be more efficient for employers to encourage brief "coffee naps," which are more effective at returning people to an alert state than either caffeine or naps alone. A "coffee nap" is when you drink a cup of coffee, and then take a sub-20-minute nap immediately afterward. This works because caffeine takes about 20 minutes to get into your bloodstream, and a 20-minute nap clears adenosine from your brain without putting you into deeper stages of sleep. In multiple studies, tired participants who took coffee naps made fewer mistakes in a driving simulator after they awoke than the people who drank coffee without a nap or slept without ingesting caffeine.

Fox and Dish have been locking horns over Dish over its streaming and PVR services for a while now, and immediately after the Aereo ruling Fox sought an injunction against Dish's services. The court rejected the request. From the article: Fox pointed out the Supremes had reflected Aereo's argument (which it said was Dish's as well) that a performance was not public under the Copyright Act if each sub watches a unique stream. Fox's lawyer, Richard Stone, argued that Aereo was also essentially about attaching a Slingbox to a DVR. But that got some pushback. One judge countered that it was "completely different technology" and said that while that was the argument, "the Supreme court has all sorts of caveats in the opinion about how this was about Aereo and nothing else and a lot of the 'nothing elses' seem to be pretty similar to Slingbox." The underlying case will continue moving forward (going to trial in early 2015).

Taco Cowboy writes The subway system in Hong Kong has one of the best uptimes: 99.9%, which beats London's tube or NYC's sub hands down. In an average week as many as 10,000 people would be carrying out 2,600 engineering works across the system — from grinding down rough rails to replacing tracks to checking for damages. While human workers might be the ones carrying out the work, the one deciding which task is to be worked on, however, isn't a human being at all. Each and every engineering task to be worked on and the scheduling of all those tasks is being handled by an algorithm. Andy Chun of Hong Kong's City University, who designed the AI system, says, "Before AI, they would have a planning session with experts from five or six different areas. It was pretty chaotic. Now they just reveal the plan on a huge screen." Chun's AI program works with a simulated model of the entire system to find the best schedule for necessary engineering works. From its omniscient view it can see chances to combine work and share resources that no human could. However, in order to provide an added layer of security, the schedule generated by the AI is still subject to human approval — Urgent, unexpected repairs can be added manually, and the system would reschedule less important tasks. It also checks the maintenance it plans for compliance with local regulations. Chun's team encoded into machine readable language 200 rules that the engineers must follow when working at night, such as keeping noise below a certain level in residential areas. The main difference between normal software and Hong Kong's AI is that it contains human knowledge that takes years to acquire through experience, says Chun. "We asked the experts what they consider when making a decision, then formulated that into rules – we basically extracted expertise from different areas about engineering works," he says.

The Fuel 3-D website has a blurb that says, "The world’s first handheld point-and-shoot, full color 3D scanner. Our planned list price is $1500 but by placing your advanced order now you pay only $1,250. Fire up your creativity!" We've thought about getting a 3-D scanner ever since we first messed with a 3-D printer, but we've thought more about something in the sub-$300 price range than in $1000+ territory. But that's just us. There is no doubt a healthy market for 3-D scanners to use in commercial applications where $1250 (or even $1500) is hardly worth noticing. Ah, well. Maybe we need to look at the The DAVID website which describes their device as an "Incredibly Low-Cost 3D Scanner for Everyone!" Their 3-D starter kit is only $529 from a randomly-selected U.S. reseller, which isn't too bad compared to the alternatives. But waiting for prices in this market niche to come down is another possibility, and it's one a whole lot of individuals -- including us -- and smaller companies will probably choose.

Hugh Pickens DOT Com writes "Benedict Carey reports at the NYT that the uncertainties surrounding Malaysia Airlines Flight 370's disappearance are enormous, but naval strategists have been unraveling lost-at-sea mysteries as far back as the U-boat battles of World War II, and perhaps most dramatically in 1968, when an intelligence team found the submarine Scorpion, which sank in the North Atlantic after losing contact under equally baffling circumstances. "The same approach we used with Scorpion could be applied in this case and should be," says John P. Craven who helped pioneer the use of Bayesian search techniques to locate objects lost at sea. "But you need to begin with the right people." The approach is a kind of crowdsourcing, but not one in which volunteers pored over satellite images, like they have in search of Flight 370. "That effort is akin to good Samaritans combing a forest for a lost child without knowing for certain that the child is there," writes Carey.

Instead, forecasters draw on expertise from diverse but relevant areas — in the case of finding a submarine, say, submarine command, ocean salvage, and oceanography experts, as well as physicists and engineers. Each would make an educated guess as to where the ship is, based on different scenarios: the sub was attacked; a torpedo activated onboard; a battery exploded. Craven's work was instrumental in the Navy's search for the missing hydrogen bomb that had been lost in the Mediterranean Sea, off the coast of Spain in 1966 and this is how Craven located the Scorpion. "I knew these guys and I gave probability scores to each scenario they came up with," says Craven. The men bet bottles of Chivas Regal to keep matters interesting, and after some statistical analysis, Craven zeroed in on a point about 400 miles from the Azores, near the Sargasso Sea. The sub was found about 200 yards away.

In the case of the downed Malaysian plane, forecasters might bring in climate and ocean scientists, engineers who worked on building the plane's components and commercial pilots familiar with the route. Those specialists would then make judgments based on the scenarios already discussed as possible causes for the disappearance of Flight 370: terrorism, pilot error, sudden depressurization and engine failure. Sound-detection technology in and around the Indian Ocean may aid this forecasting. The sound of the airliner's fall — if it hit the water — might already have been picked up by submarines watching each other. "In that case the information would be classified," says former submarine commander Alfred Scott McLare, "and we wouldn't know anything until it was released through back channels somehow.""

itwbennett writes "Yesterday, a story suggesting that Amazon was planning to launch a sub-$300 Android game console made the rounds. A $300 box to play mobile games on your TV? ITworld's Peter Smith doesn't buy it. 'If Amazon is working on some kind of set-top box, it's going to be about streaming,' says Smith. 'Music, video, and games. Remember back in November when Amazon announced G2, a new AWS instance type designed for streaming GPU intensive tasks like games? Combine Amazon's G2 cloud servers and an Amazon set top box for console-like game streaming, plus supporting Android and/or iOS games (possibly the latter would also be streamed), and of course support for Amazon Video and MP3, and we're getting closer to something that may be worth $300.'"

New submitter silverjacket writes "New research (JSTOR sub required / paywalled) shows that we see nonconformity as a sign of both status and competence — under the right conditions. From the article: 'Next, the researchers asked students at American universities to imagine a professor who is clean-shaven and wears a tie, or one who is bearded and wears T-shirts. Students were slightly more inclined to judge the dapper professor as a better teacher and researcher. But some students were given another piece of information: that the professor works at a top-tier school, where the dress code is presumably more formal. For them, the slouchy scholar earned more points. Deviance can signal status, but only when there are clear norms from which to deviate.'"
