HughPickens.com writes: It's common knowledge the NSA collects plenty of data on suspected terrorists as well as ordinary citizens, but the agency also has algorithms in place to filter out information that doesn't need to be collected or stored for further analysis, such as spam emails. Now Alice Truong reports that during operations in Afghanistan after 9/11, the U.S. was able to analyze laptops formerly owned by Taliban members. According to NSA officer Michael Wertheimer, they discovered an email written in English found on the computers contained a purposely spammy subject line: "CONSOLIDATE YOUR DEBT."

According to Wertheimer, the email was sent to and from nondescript addresses that were later confirmed to belong to combatants. "It is surely the case that the sender and receiver attempted to avoid allied collection of this operational message by triggering presumed "spam" filters (PDF)." From a surveillance perspective, Wertheimer writes that this highlights the importance of filtering algorithms. Implementing them makes parsing huge amounts of data easier, but it also presents opportunities for someone with a secret to figure out what type of information is being tossed out and exploit the loophole.

dcblogs writes New legislation being pushed by Sen. Orrin Hatch (R-Utah) to hike the H-1B visa cap is drawing criticism and warnings that it will lead to an increase in offshoring of tech jobs. IEEE-USA said the legislation, introduced by a bipartisan group of lawmakers on Tuesday, will "help destroy" the U.S. tech workforce with guest workers. Other critics, including Ron Hira, a professor of public policy at Howard University and a leading researcher on the issue, said the bill gives the tech industry "a huge increase in the supply of lower-cost foreign guest workers so they can undercut and replace American workers." Hira said this bill "will result in an exponential rise of American jobs being shipped overseas." Technically, the bill is a reintroduction of the earlier "I-Square" bill, but it includes enough revisions to be considered new. It increases the H-1B visa cap to 195,000 (instead of an earlier 300,000 cap), and eliminates the cap on people who earn an advanced degree in a STEM (science, technology, education and math) field. Hatch, who is the No. 2 ranking senator in the GOP-controlled chamber, was joined by co-sponsors Amy Klobuchar (D-Minn.), Marco Rubio (R-Fla.), Chris Coons (D-Del.), Jeff Flake (R-Ariz.) and Richard Blumenthal (D-Conn.) in backing the legislation."

Trailrunner7 writes In a new article in an academic math journal, the NSA's director of research says that the agency's decision not to withdraw its support of the Dual EC_DRBG random number generator after security researchers found weaknesses in it and questioned its provenance was a "regrettable" choice. Michael Wertheimer, the director of researcher at the National Security Agency, wrote in a short piece in Notices, a publication of the American Mathematical Society, that even during the standards development process for Dual EC many years ago, members of the working group focused on the algorithm raised concerns that it could have a backdoor in it. The algorithm was developed in part by the NSA and cryptographers were suspect of it from the beginning. "With hindsight, NSA should have ceased supporting the dual EC_DRBG algorithm immediately after security researchers discovered the potential for a trapdoor. In truth, I can think of no better way to describe our failure to drop support for the Dual_EC_DRBG algorithm as anything other than regrettable," Wertheimer wrote in a piece in Notices' February issue.

jones_supa writes A lot of development work is happening on systemd with just the recent couple of weeks seeing over 200 commits. With the most recent work that has landed, the networkd component has been improved with new features. Among the additions are IP forwarding and masquerading support (patch). This is the minimal support needed and these settings get turned on by default for container network interfaces. Also added was minimal firewall manipulation helpers for systemd's networkd. The firewall manipulation helpers (patch) are used for establishing NAT rules. This support in systemd is provided by libiptc, the library used for communicating with the Linux kernel's Netfilter and changing iptables firewall rulesets. Those wishing to follow systemd development on a daily basis and see what is actually happening under the hood, can keep tabs via the systemd Git viewer.

HughPickens.com writes: Lily Hay Newman reports that the LAPD has ordered 3,000 Tasers which, when discharged, will automatically activate cameras on officers' uniforms, creating visual records of incidents at a time of mounting concern about excessive force by U.S. law enforcement officers. The new digital Taser X26P weapons record the date, time, and duration of firing, and whether Taser wires actually strike suspects and how long the thousands of volts of electricity pulse through them. "This technology gives a much better picture of what happens in the field," says Steve Tuttle.

The idea of using a Taser discharge as a criterion for activating body cams is promising, especially as more and more police departments adopt body cams and struggle to establish guidelines for when they should be on or off. Police leadership — i.e., chiefs and upper management — is far more supportive of the technology and tends to view body-worn cameras as a tool for increasing accountability and reducing civil liability. On the other hand, the patrol officer culture is concerned that the technology will be an unfair intrusion into their routine activities — for instance, it might invite over-managing minor policy violations. "In addition to these new Taser deployments, we plan to issue a body-worn camera and a Taser device to every officer," says Police Chief Charlie Beck. "It is our goal to make these important tools available to every front line officer over the next few years."

BarbaraHudson writes: Robonaut 2, now in orbit on board the International Space Station, has run into problems with the software controlling its new legs. From the article: "The machine ran into a few technical errors. According to NASA, the ground teams deployed Robonaut's software and received telemetry from the robot, but were unable to obtain the correct commands for the leg movement, which are vital to performing every day tasks aboard the International Space Station. Ground teams have begun assessing how to move forward with this issue, though it is unclear if they currently have a fix in mind."

An anonymous reader writes with this story about who will lead the IoT revolution, and whether it will follow in mobile's footsteps. "As these technologies sense and and react to changes in your environment, there are obvious parallels to computer operating systems, which receive input and return output. What does the 'operating system' for the smart home of the future look like? Alex Hawkinson is trying to help answer that very question. The founder and CEO of IoT company SmartThings is not only a leader in the market, he’s a consumer. He suggests there won’t be a singular, cohesive operating system for your home, that this stuff isn’t one-size-fits-all. 'I think it’s up to everyone to determine their own bits,' Hawkinson said. 'Some people love cameras in house, my wife wants none. It’s up to your preferences.'”

DeviceGuru writes: Erle Robotics has launched what is claimed to be the first drone to run both a Pixhawk APM autopilot and ROS directly on Linux. Over the last year Erle Robotics and 3DRobotics have collaborated on developing an open source, all-Linux BeagleBone Black-based autopilot for drones using the popular 3DR APM architecture, but without using Nuttx RTOS for the real-time bits. In addition to being used on a new 'Erle-copter' quadcopter drone, the new all-Linux 'Erle-brain' APM will ship in both a two-winged UAV and a four-wheeled robotic vehicle, due next spring.

An anonymous reader writes with news about an affordable way to integrate touch screen technology in any car. "Although touchscreen controls are appearing in the dashboards of an increasing number of vehicles, they're still not something that one generally associates with economy cars. That may be about to change, however, as Continental has announced an "infrared curtain" system that could allow for inexpensive multi-touch functionality in any automobile. The infrared curtain consists of a square frame with a series of LEDs along two adjacent sides, and a series of photodiodes along the other two. Each LED emits a beam of infrared light, which is picked up and converted into an electrical signal by the photodiode located in the corresponding spot on the opposite side of the frame."

cartechboy writes The common assumption among Tesla fans seems to be that state auto-dealer lobbyists are working with Republican legislators to enact laws banning direct sales of Tesla's electric cars to retail buyers. Is it true? The New York Times published an article with some data points that assesses the supposition. While the article mainly focuses on the conflict between Uber and the Republican party, some quotes could be easily applied to Tesla. For instance, Republican National Committee chairman Reince Preibus said, "It should be consumers, not government bureaucrats or legislators, that deicde what companies get our business." The author of the article, Josh Barro, wrote that 22 states permit direct sales of automobiles by Tesla to retail buyers, and of those the majority--14 of them-- voted for President Obama. He suggested that Democratic California, Illinois, and New York "have freer markets in auto retailing than Texas," which is presently Republican. When looking at a five-year-old article by Nate Silver that looked at political donations by car dealers, fully 88 percent of those donations went to Republican candidates, and just 12 percent to Democrats. That possibly suggests a propensity among Republican state legislators to support the interests for car dealers over those of electric-car buyers. Is the small bit of evidence enough to make a case? Good background on the current system of dealership sinecure can be found in this short 2009 Competition Advocacy Paper from the U.S. Department of Justice, which delves into the history and effects of the dealers-only system which still prevails.

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."

HughPickens.com writes The NYT reports that Peruvian authorities say Greenpeace activists have damaged the fragile, and restricted, landscape near the Nazca lines, ancient man-made designs etched in the Peruvian desert when they placed a large sign that promoted renewable energy near a set of lines that form the shape of a giant hummingbird. The sign was meant to draw the attention of world leaders, reporters and others who were in Lima, the Peruvian capital, for a United Nations summit meeting aimed at reaching an agreement to address climate change. Greenpeace issued a statement apologizing for the stunt at the archaeological site and its international executive director, Kumi Naidoo, flew to Lima to apologize for scarring one of Peru's most treasured national symbols. "We are not ready to accept apologies from anybody," says Luis Jaime Castillo, the vice minister for cultural heritage. "Let them apologize after they repair the damage."

Yesterday, we posted news that data from the European Space Agency's XMM-Newton spacecraft had been interpreted as a possible sign of dark matter; researchers noted that a spike in X-ray emissions from two different celestial objects, the Andromeda galaxy and the Perseus galaxy cluster, matched just what they "were expecting with dark matter — that is, concentrated and intense in the center of objects and weaker and diffuse on the edges." StartsWithABang writes with a skeptical rejoinder: There seems to be a formula for this very specific extraordinary claim: point your high-energy telescope at the center of a galaxy or cluster of galaxies, discover an X-ray or gamma ray signal that you can't account for through conventional, known astrophysics, and claim you've detected dark matter! Only, these results never pan out; they've turned out either to be due to conventional sources or simply non-detections every time. There's a claim going around the news based on this paper recently that we've really done it this time, and yet that's not even physically possible, as our astrophysical constraints already rule out a particle with this property as being the dark matter!

An anonymous reader sends this quote from the Center for Public Integrity: That AT&T just won an eight-figure contract to provide the federal government's General Services Administration with new mobile devices isn't itself particularly notable. What is: Casey Coleman, an AT&T executive responsible for "delivering IT and professional services to federal government customers," oversaw the GSA's information technology division and its $600 million IT budget as recently as January. ... While there’s no evidence anything illegal took place, the public still should be aware of, and potentially worried about, Coleman’s spin through the revolving door between government and companies that profit from government, said Michael Smallberg, an investigator at the nonpartisan watchdog group Project on Government Oversight. ... Federal government employees leaving public service for lucrative private sector jobs is commonplace. The Project on Government Oversight has called on the federal government to — among other actions — ban political appointees and some senior-level staffers from seeking employment with contractors that “significantly benefited” from policies they helped formulate during their tenure in government.
