High Speed DIY M&M Sorting Machine Uses iPhone Brain
HughPickens.com writes: Canoe Tech reports that M&M sorting machines are a popular project for people who like combining electronics, programming and machine building. Most of them send a single M&M down a chute to a simple color sensor where the color sensor will then take a second or two to figure out the color. A servo motor will then rotate a chute that will direct the M&M into the correct pot. But a new project created by the nameless blogger behind the reviewmylife blog that uses an iPhone 5s as its brain is capable of sensing different colors and so can "sort" the M&Ms as they fall past. The iPhone communicates the information via Bluetooth to an Arduino board, which in turn fires off the correct electro magnet controlled gate. One practical application of the sorter could be creating a bowl of M&Ms — with all the brown ones removed.

Crowds (and Pirates) Flock To 'The Interview'
Rambo Tribble writes: Many of the 300+ theaters showing The Interview on Christmas were rewarded with sell-out crowds. While reviews of the comedy have been mixed, many movie-goers expressed solidarity with the sentiment of professor Carlos Royal: "I wanted to support the U.S." Despite sellout crowds, the movie's limited release meant it only brought in about $1 million on opening day (compared to $10M+ for the highest-grossing films). Curiosity about the film seems high, since hundreds of thousands rushed to torrent the film, and others figured out an extremely easy way to bypass Sony's DRM.

How Target's Mobile App Uses Location Tech To Track You
An anonymous reader writes Big-box retailers are figuring out how to use mobile apps to drive in-store sales, but they're also concerned about privacy. To see how they're doing, Xconomy took Target's app for a spin on one of the busiest shopping days of the year. The app uses indoor location-mapping technology from a startup called Point Inside. The verdict? The app saved a few minutes in locating items around the store, but it would work better if it knew where shoppers (and the items on their lists) are at any time. With Apple's iBeacons set to roll out more widely, retail privacy will be a hot issue in 2015.

Study: Police Body-Cams Reduce Unacceptable Use of Force
An anonymous reader writes: Incidents like the Michael Brown case have recently put police body-worn cameras into the public consciousness, but they're not a new idea to criminology experts. In fact, researchers at Cambridge began a study in 2012 using law enforcement in Rialto, California as a test bed. Their results are now in: "The experiment showed that evidence capture is just one output of body-worn video, and the technology is perhaps most effective at actually preventing escalation during police-public interactions: whether that's abusive behavior towards police or unnecessary use-of-force by police." The simple knowledge that both parties are being watched puts a damper on violence. "During the 12-month Rialto experiment, use-of-force by officers wearing cameras fell by 59% and reports against officers dropped by 87% against the previous year's figures." This was enough for the city of Rialto to decide it wants to move forward with body-worn cameras; hopefully the study will encourage other police departments as well.

How a Massachusetts Man Invented the Global Ice Market
An anonymous reader writes with the story of Frederic Tudor, the man responsible for the modern food industry. "A guy from Boston walks into a bar and offers to sell the owner a chunk of ice. To modern ears, that sounds like the opening line of a joke. But 200 years ago, it would have sounded like science fiction—especially if it was summer, when no one in the bar had seen frozen water in months. In fact, it's history. The ice guy was sent by a 20-something by the name of Frederic Tudor, born in 1783 and known by the mid-19th century as the "Ice King of the World." What he had done was figure out a way to harvest ice from local ponds, and keep it frozen long enough to ship halfway around the world.
Today, the New England ice trade, which Tudor started in Boston's backyard in 1806, sounds cartoonishly old-fashioned. The work of ice-harvesting, which involved cutting massive chunks out of frozen bodies of water, packing them in sawdust for storage and transport, and selling them near and far, seems as archaic as the job of town crier. But scholars in recent years have suggested that we're missing something. In fact, they say, the ice trade was a catalyst for a transformation in daily life so powerful that the mark it left can still be seen on our cultural habits even today. Tudor's big idea ended up altering the course of history, making it possible not only to serve barflies cool mint juleps in the dead of summer, but to dramatically extend the shelf life and reach of food. Suddenly people could eat perishable fruits, vegetables, and meat produced far from their homes. Ice built a new kind of infrastructure that would ultimately become the cold, shiny basis for the entire modern food industry." -
Finland Announces an Anti-Laser Campaign For Air Traffic
jones_supa writes Trafi, the Finnish Pilots' Association, and STUK, the Finnish Radiation and Nuclear Safety Authority, have launched a joint campaign against air traffic interference with the title "Lasers Are Not Toys." Ilkka Kaakinen from Trafi says that laser pointers interfering with air traffic is a real problem in Finland. "We receive reports of several cases of laser interference every month and every one of them is potentially dangerous," Kaakinen says. Last year, 60 cases of laser pointer interference were reported in Finland, and the figure for this year was at 58 in November. Despite the continuing interference, only one person has been caught misusing a laser pointer in this way in Finland. That single person was not convicted of a crime, as the court was not able to establish intent. Kaakinen says other countries hand down severe punishments for interfering with air traffic, even years-long stretches in prison. He also reminds that it is important for users of laser pointers to understand that the devices are not toys, and that children should be warned of the potential danger in using them irresponsibly – or ideally, not given one at all.

What Happens To Society When Robots Replace Workers?
Paul Fernhout writes: An article in the Harvard Business Review by William H. Davidow and Michael S. Malone suggests: "The "Second Economy" (the term used by economist Brian Arthur to describe the portion of the economy where computers transact business only with other computers) is upon us. It is, quite simply, the virtual economy, and one of its main byproducts is the replacement of workers with intelligent machines powered by sophisticated code. ... This is why we will soon be looking at hordes of citizens of zero economic value. Figuring out how to deal with the impacts of this development will be the greatest challenge facing free market economies in this century. ... Ultimately, we need a new, individualized, cultural, approach to the meaning of work and the purpose of life. Otherwise, people will find a solution — human beings always do — but it may not be the one for which we began this technological revolution."
This follows the recent Slashdot discussion of "Economists Say Newest AI Technology Destroys More Jobs Than It Creates" citing a NY Times article and other previous discussions like Humans Need Not Apply. What is most interesting to me about this HBR article is not the article itself so much as the fact that concerns about the economic implications of robotics, AI, and automation are now making it into the Harvard Business Review. These issues have been otherwise discussed by alternative economists for decades, such as in the Triple Revolution Memorandum from 1964 — even as those projections have been slow to play out, with automation's initial effect being more to hold down wages and concentrate wealth rather than to displace most workers. However, they may be reaching the point where these effects have become hard to deny despite going against mainstream theory which assumes infinite demand and broad distribution of purchasing power via wages.
As to possible solutions, there is a mention in the HBR article of using government planning by creating public works like infrastructure investments to help address the issue. There is no mention in the article of expanding the "basic income" of Social Security currently only received by older people in the U.S., expanding the gift economy as represented by GNU/Linux, or improving local subsistence production using, say, 3D printing and gardening robots like Dewey of "Silent Running." So, it seems like the mainstream economics profession is starting to accept the emerging reality of this increasingly urgent issue, but is still struggling to think outside an exchange-oriented box for socioeconomic solutions. A few years ago, I collected dozens of possible good and bad solutions related to this issue. Like Davidow and Malone, I'd agree that the particular mix we end up will be a reflection of our culture. Personally, I feel that if we are heading for a technological "singularity" of some sort, we would be better off improving various aspects of our society first, since our trajectory going out of any singularity may have a lot to do with our trajectory going into it. -
Graphene: Fast, Strong, Cheap, and Impossible To Use
An anonymous reader writes: We keep hearing about the revolutionary properties of graphene, an atom-thick sheet of carbon whose physical characteristics hold a great deal of promise — if we can figure out good ways to produce it and use it. The New Yorker has a lengthy profile of graphene and its discoverer, Andre Geim, as well as one of the physicists leading a big chunk of the bleeding-edge graphene research, James Tour.
Quoting: "[S]cientists are still trying to devise a cost-effective way to produce graphene at scale. Companies like Samsung use a method pioneered at the University of Texas, in which they heat copper foil to eighteen hundred degrees Fahrenheit in a low vacuum, and introduce methane gas, which causes graphene to "grow" as an atom-thick sheet on both sides of the copper—much as frost crystals "grow" on a windowpane. They then use acids to etch away the copper. The resulting graphene is invisible to the naked eye and too fragile to touch with anything but instruments designed for microelectronics. The process is slow, exacting, and too expensive for all but the largest companies to afford. ... Nearly every scientist I spoke with suggested that graphene lends itself especially well to hype." -
How Birds Lost Their Teeth
An anonymous reader writes A research team from the University of California, Riverside and Montclair State University, New Jersey, have found that the lack of teeth in all living birds can be traced back to a common ancestor who lived about 116 million years ago. From the article: "To solve this puzzle, the researchers used a recently created genome database that catalogues the genetic history of nearly all living bird orders--48 species in total. They were looking for two specific types of genes: one responsible for dentin, the substance that (mostly) makes up teeth, and another for the enamel that protects them. Upon finding these genes, researchers then located the mutations that deactivate them, and combed the fossil record to figure out when those mutations developed. They concluded that the loss of teeth and the development of the beak was a two-stage process, though the steps basically happened simultaneously. The paper states: 'In the first stage, tooth loss and partial beak development began on the anterior portion of both the upper and lower jaws. The second stage involved concurrent progression of tooth loss and beak development from the anterior portion of both jaws to the back of the rostrum.'"

Vinyl Record Pressing Plants Struggle To Keep Up With Demand
An anonymous reader writes The WSJ reports that the revival of vinyl records, a several-year trend that many figured was a passing fad, has accelerated during 2014 with an astounding 49 percent sales increase over 2013 (line chart here). Some listeners think that vinyl reproduces sound better than digital, and some youngsters like the social experience of gathering around a turntable. The records are pressed at a handful of decades-old, labor-intensive factories that can't keep up with the demand; but since the increased sales still represent only about 2 percent of US music sales, there hasn't been a rush of capital investment to open new plants. Raw vinyl must now be imported to America from countries such as Thailand, since the last US supplier closed shop years ago. Meanwhile, an industry pro offers his take on the endless debate of audio differences between analog records and digital formats; it turns out there were reasons for limiting playing time on each side back in the day, apart from bands not having enough decent material.

Apple Antitrust Case Finds New Consumer Plaintiff
An anonymous reader writes Class action against Apple is set to continue after 65-year-old amateur figure skater Barbara Bennett decided she would volunteer to represent consumers in the faltering antitrust case. U.S. district judge Yvonne Gonzalez-Rogers is reportedly satisfied that Bennett qualifies as a class member, telling attorneys that they 'were on the right track.' Bennett offered to volunteer in the case after reading an online news story which suggested that the suit was floundering due to a lack of a named plaintiff after the last plaintiff was disqualified earlier this week.

Is Enterprise IT More Difficult To Manage Now Than Ever?
colinneagle writes: Who's old enough to remember when the best technology was found at work, while at home we got by with clunky home computers and pokey dial-up modems? Those days are gone, and they don't look like they're ever coming back.
Instead, today's IT department is scrambling to deliver technology offerings that won't get laughed at — or, just as bad, ignored — by a modern workforce raised on slick smartphones and consumer services powered by data centers far more powerful than the one their company uses. And those services work better and faster than the programs they offer, partly because consumers don't have to worry about all the constraints that IT does, from security and privacy to, you know, actually being profitable. Plus, while IT still has to maintain all the old desktop apps, it also needs to make sure mobile users can do whatever they need to from anywhere at any time.
And that's just the users. IT's issues with corporate peers and leaders may be even rockier. Between shadow IT and other Software-as-a-Service, estimates say that 1 in 5 technology operations dollars are now being spent outside the IT department, and many think that figure is actually much higher. New digital initiatives are increasingly being driven by marketing and other business functions, not by IT. Today's CMOs often outrank the CIO, whose role may be constrained to keeping the infrastructure running at the lowest possible cost instead of bringing strategic value to the organization. Hardly a recipe for success and influence. -
Neglecting the Lessons of Cypherpunk History
Nicola Hahn writes Over the course of the Snowden revelations there have been a number of high profile figures who've praised the merits of encryption as a remedy to the quandary of mass interception. Companies like Google and Apple have been quick to publicize their adoption of cryptographic countermeasures in an effort to maintain quarterly earnings. This marketing campaign has even convinced less credulous onlookers like Glenn Greenwald. For example, in a recent Intercept piece, Greenwald claimed:
"It is well-established that, prior to the Snowden reporting, Silicon Valley companies were secret, eager and vital participants in the growing Surveillance State. Once their role was revealed, and they perceived those disclosures threatening to their future profit-making, they instantly adopted a PR tactic of presenting themselves as Guardians of Privacy. Much of that is simply self-serving re-branding, but some of it, as I described last week, are genuine improvements in the technological means of protecting user privacy, such as the encryption products now being offered by Apple and Google, motivated by the belief that, post-Snowden, parading around as privacy protectors is necessary to stay competitive."
So, while he concedes the role of public relations in the ongoing cyber security push, Greenwald concurrently believes encryption is a "genuine" countermeasure. In other words, what we're seeing is mostly marketing hype... except for the part about strong encryption.
With regard to the promise of encryption as a privacy cure-all, history tells a markedly different story. Guarantees of security through encryption have often proven illusory, a magic act. Seeking refuge in a technical quick fix can be hazardous for a number of reasons. -
Programmer Father Asks: What Gets Little Girls Interested In Science?
nbauman writes Programmer David Auerbach is dismayed that, at a critical developmental age, his 4-year-old daughter wants to be a princess, not a scientist or engineer, he writes in Slate. The larger society keeps forcing sexist stereotypes on her, in every book and toy store. From the article: "Getting more women into science and technology fields: Where’s the silver bullet? While I might get more hits by revealing the One Simple Trick to increase female participation in the sciences, the truth is there isn’t some key inflection point where young women’s involvement drops off. Instead, there is a series of small- to medium-sized discouraging factors that set in from a young age, ranging from unhelpful social conditioning to a lack of role models to unconscious bias to very conscious bias. Any and all of these can figure into why, for example, women tend to underrate their technical abilities relative to men. I know plenty of successful women in the sciences, but let’s not fool ourselves and say the playing field in the academic sciences or the tech world is even. My wife attributes her pursuit of programming to being a loner and pretty much ignoring wider society while growing up: 'Being left alone with a computer (with NO INTERNET TO TELL ME WHAT I COULDN’T DO) was the deciding factor,' she tells me."

Renewables Are Now Scotland's Biggest Energy Source
AmiMoJo writes Government figures revealed that Scotland is now generating more power from "clean" technologies than nuclear, coal and gas. The combination of wind, solar and hydroelectric, along with less-publicized sources such as landfill gas and biomass, produced 10.3TWh in the first half of 2014. Over the same period, Scotland generated 7.8TWh from nuclear, 5.6TWh from coal and 1.4TWh from gas, according to figures supplied by National Grid. Renewable sources tend to fluctuate throughout the year, especially in Scotland where the weather is notoriously volatile, but in six-month chunks the country has consistently increased its renewable output.

Bitcoin Is Not Anonymous After All
Taco Cowboy points out a new study that shows it is possible to figure out the IP address of someone who pays for transactions anonymously online using bitcoins. "The Bitcoin system is not managed by a central authority, but relies on a peer-to-peer network on the Internet. Anyone can join the network as a user or provide computing capacity to process the transactions. In the network, the user's identity is hidden behind a cryptographic pseudonym, which can be changed as often as is wanted. Transactions are signed with this pseudonym and broadcast to the public network to verify their authenticity and attribute the Bitcoins to the new owner. In their new study, researchers at the Laboratory of Algorithmics, Cryptology and Security of the University of Luxembourg have shown that Bitcoin does not protect user's IP address and that it can be linked to the user's transactions in real-time. To find this out, a hacker would need only a few computers and about €1500 per month for server and traffic costs. Moreover, the popular anonymization network "Tor" can do little to guarantee Bitcoin user's anonymity, since it can be blocked easily."

Revisiting Open Source Social Networking Alternatives
reifman writes Upstart social networking startup Ello burst on the scene in September with promises of a utopian, post-Facebook platform that respected user's privacy. I was surprised to see so many public figures and media entities jump on board — mainly because of what Ello isn't. It isn't an open source, decentralized social networking technology. It's just another privately held, VC-funded silo. Remember Diaspora? In 2010, it raised $200,641 on Kickstarter to take on Facebook with "an open source personal web server to share all your stuff online." Two years later, they essentially gave up, leaving their code to the open source community to carry forward. In part one of "Revisiting Open Source Social Networking Alternatives," I revisit/review six open source social networking alternatives in search of a path forward beyond Facebook.

Two Google Engineers Say Renewables Can't Cure Climate Change
_Sharp'r_ writes Two Stanford PhDs, Ross Koningstein and David Fork, worked for Google on the RE<C project to figure out how to make renewables cheaper than coal and solve climate change. After four years of study they gave up, determining "Renewable energy technologies simply won't work; we need a fundamentally different approach." As a result, is nuclear going to be acknowledged as the future of energy production?

Mozilla's 2013 Report: Revenue Up 1% To $314M; 90% From Google
An anonymous reader writes Mozilla has released its annual financial report for 2013, and the numbers hint as to why the organization signed a five-year deal with Yahoo, announced by the duo on November 19. Revenue increased just 1 percent, and the organization's reliance on Google stayed flat at 90 percent. The total revenue for the Mozilla Foundation and its subsidiaries in 2011 was $163 million, and it increased 90.2 percent to $311 million for 2012. Yet that growth all but disappeared last year, as the total revenue moved up less than 1 percent (0.995 percent to be more precise) to $311 million in 2013. 85 percent of Mozilla's revenue came from Google in 2011, and that figure increased to 90 percent in 2012. While the 90 percent number remained for 2013, it's still a massive proportion and shows Mozilla last year could not figure out a way to differentiate where its money comes from.

It's Not Developers Slowing Things Down, It's the Process
An anonymous reader writes: Software engineers understand the pace of writing code, but frequently managers don't. One line of code might take 1 minute, and another line of code might take 1 day. But generally, everything averages out, and hitting your goals is more a function of properly setting your goals than of coding quickly or slowly. Sprint.ly, a company than analyzes productivity, has published some data to back this up. The amount of time actually developing a feature was a small and relatively consistent portion of its lifetime as a work ticket. The massively variable part of the process is when "stakeholders are figuring out specs and prioritizing work." The top disrupting influences (as experienced devs will recognize) are unclear and changing requirements. Another big cause of slowdowns is interrupting development work on one task to work on a second one. The article encourages managers to let devs contribute to the process and say "No" if the specs are too vague. Is there anything you'd add to this list?
