StartsWithABang writes: You might think that, when it comes to finding the most distant objects in the Universe, all we need is a good telescope, to leave the shutter open, and wait. As we accumulate more and more photons, we're bound to find the most distant, faint objects out there. Sure, Hubble just broke its own cosmic distance record, but it's certainly not the most distant. Thinking so misses an important fact: the Universe is expanding! And with that expansion, the wavelength of the light we can see gets redshifted. Ultraviolet light winds up in the infrared, infrared light winds up in the microwave, and the most distant galaxies that are out there are invisible, even to Hubble. Here are Hubble's limits, and how the James Webb Space Telescope will overcome them.

French Version of 'Patriot Act' Becomes Law 50

Posted by Soulskill
from the privacy-surrenders dept.
Taco Cowboy writes: Thanks to the Charlie Hebdo massacre and other instances of terrorism, the French legislature has voted 438 to 86 in favor of the "Intelligence Service Bill," essentially a French version of the Patriot Act. It awards the French intelligence services sweeping powers to tap and intercept any kind of digital correspondence, including phone conversations, emails, and social media.

The bill decrees that hosting providers and Internet service providers in France must be equipped with a "black box" that can retain all digital communications from customers. "The new law would create a 13-member National Commission to Control Intelligence Techniques, which would be made up of six magistrates from the Council of State and the Court of Appeals, three representatives of the National Assembly, three senators from the upper house of Parliament and a technical expert. ... The only judicial oversight is a provision that allows the commission to lodge a complaint with the Council of State, but lawyers are doubtful that it could be convened on a routine basis." We previously discussed news that ISPs may leave France in protest if the bill was passed. Now we'll know shortly if those ISPs will live up to their word.

The World's Most Wasteful Megacity 60

from the it's-new-york dept.
merbs writes: The world's most wasteful megacity is a densely populated, steadily aging, consumerist utopia where we buy, and throw away, a staggering amount of stuff (abstract). Where some faucet, toilet, or pipe, is constantly leaking in our apartments. Where an armada of commerce-beckoning lights are always on. Where a fleet of gas-guzzling cars still clog the roadways. I, along with my twenty million or so neighbors, help New York City use more energy, suck down more water, and spew out more solid waste than any other mega-metropolitan area.

An anonymous reader writes: LiveScience reports on strange sounds recorded by microphones on board a high altitude balloon. The sounds were captured at altitudes of up to 36 kilometers, higher than any such experiment to date. Most of the noises are in Infrasound frequencies — below 20 Hz. Researchers aren't sure what caused the noises, but they have a few theories: "a wind farm under the balloon's flight path, crashing ocean waves, wind turbulence, gravity waves, clear air turbulence, and vibrations caused by the balloon cable."

The Ambitions and Challenges of Mesh Networks and the Local Internet Movement 34

from the net-positives-and-net-negatives dept.
Lashdots writes: Two artists in New York are hatching a plan to teach kids about the internet by building their own. They'll be creating a small, decentralized network, similar to a mesh network, to access other computers, and they'll be developing their own simple social network to communicate with other people. It's part of a growing movement to supplement the Internet with resilient, local alternatives. "And yet, while the decentralized, ad hoc network architecture appeals philosophically to tech-savvy users fed up with monopolistic ISPs, nobody’s found a way to make mesh networks work easily and efficiently enough to replace home Internet connections. Built more for resiliency than for speed, each participating router must continuously search for the best paths to far-flung machines. For now, that makes them of limited interest to many ordinary consumers who simply want to check their email and watch movies."

Cyberlock Lawyers Threaten Security Researcher Over Vulnerability Disclosure 53

qubezz writes: Security researcher Phar (Mike Davis/IOActive) gave his 30 days of disclosure notice to Cyberlock (apparently a company that makes electronic lock cylinders) that he would release a public advisory on vulnerabilities he found with the company's security devices. On day 29, their lawyers responded with a request to refrain, feigning ignorance of the previous notice, and invoking mention of the DMCA (this is not actually a DMCA takedown notice, as the law firm is attempting to suppress initial disclosure through legal wrangling). Mike's blog states: "The previous DMCA threats are from a company called Cyberlock, I had planned to do a fun little blog post (cause i ... hate blog posts) on the fun of how I obtained one, extracted the firmware bypassing the code protection and figured out its "encryption" and did various other fun things a lock shouldn't do for what its marketed as.. But before I could write that post I needed to let them know what issues we have deemed weaknesses in their gear.. the below axe grinderery is the results.

SpaceX Testing Passenger Escape System Tomorrow 44

Posted by Soulskill
from the coming-home-safely dept.
An anonymous reader writes: On Wednesday, SpaceX will be performing the first test of a prototype for its passenger capsule escape system. Most rockets have a launch abort system that will save the lives of its crew within the first few minutes of launch, but not beyond a relatively low altitude. SpaceX is designing the new system to be able to return astronauts safely whether they're close to the ground or near orbit.

The Dragon capsule will fire eight SuperDraco thrusters, capable of producing 120,000 lbs of axial thrust between them in under a second. With that amount of thrust, the capsule can get half a kilometer away from a failing rocket in under 5 seconds. SpaceX will have 270 sensors aboard the prototype, including a crash test dummy. The main mission goals include: determining the best sequencing for the launch abort timeline, getting all eight thrusters to fire in unison, and seeing how an aborted launch affects both the inside of the capsule and the area around it. The test is planned to start at 7 a.m. EDT (11:00 UTC), but they have a 7.5-hour window if there are minor delays.

Police Can Obtain Cellphone Location Records Without a Warrant 161

mi writes: A new ruling from the 11th Circuit Court of Appeals found by a margin of 9-2 that law enforcement does not need to get a warrant to grab your cell phone's location records. The justices ruled that there is no expectation of privacy for your location when you're using a cell phone. This decision (PDF) was based on a case in which a man was convicted of robbery after months of location data was given to authorities by his cell phone carrier, MetroPCS. Police got the information using a court order, rather than a warrant, because there were less stringent requirements involved. One of the judges wrote: "We find no reason to conclude that cellphone users lack facts about the functions of cell towers or about telephone providers' recording cell tower usage."

Google Can't Ignore the Android Update Problem Any Longer 250

Posted by Soulskill
from the i-bet-they-can dept.
An anonymous reader writes: An editorial at Tom's Hardware makes the case that Google's Android fragmentation problem has gotten too big to ignore any longer. Android 5.0 Lollipop and its successor 5.1 have seen very low adoption rates — 9.0% and 0.7% respectively. Almost 40% of users are still on KitKat. 6% lag far behind on Gingerbread and Froyo. The article points out that even Microsoft is now making efforts to both streamline Windows upgrades and adapt Android (and iOS) apps to run on Windows.

If Google doesn't adapt, "it risks having users (slowly but surely) switch to more secure platforms that do give them updates in a timely manner. And if users want those platforms, OEMs will have no choice but to switch to them too, leaving Google with less and less Android adoption." The author also says OEMs and carriers can no longer be trusted to handle operating system updates, because they've proven themselves quite incapable of doing so in a reasonable manner.

New submitter Donaithnen writes: Like many geeks, I'm against the idea of DRM in general and have championed GOG.com's DRM-free approach to selling games online. Yet like many geeks, I've also often succumbed to the temptation of Steam because of the convenience of tracking, installing, and playing my PC game purchases through the launcher (not to mention the compulsion of collecting achievements, and watching the total playtime for my favorite games (to my occasional dismay). Now, GOG has announced the open beta for GOG Galaxy, an entirely optional launcher to allow those who want (and only those who want) to have all the same features when playing GOG games.

Intel Launches Xeon E7-8800 and E7-4800 V3 Processor Families 39

Posted by Soulskill

MojoKid writes: Intel is taking the wraps off of its latest processors for enterprise server and pro workstation applications today, dubbed the Xeon E7-8800 / 4800 v3. Like its high-end desktop processors, the Xeon E7-8800 / 4800 v3 product families are based on the Haswell-EX CPU core. These new Xeons, however, offer a plethora of other enhancements and are packing significantly more cores than any current desktop processor. The highest-end Xeon E7-8800 series processors, for example, are 18 core chips. Previous generation Xeon E7 v2 processors were based on the Ivy Bridge-EX core, while the new E7 v3 parts are based on Haswell-EX, though both are manufactured on Intel's 22nm process node. Next generation Broadwell-EX based Xeons will make the move to 14nm. Xeon E7-8800 / 4800 v3 series processors have 32-lanes of PCIe 3.0 connectivity per socket, TSX is enabled in all SKUs, they offer support for both DDR3 and DDR4 memory (though, not simultaneously), and can address up to 6TB of memory in a 4-socket configuration or 12TB in an 8-socket setup. Intel has also goosed the chip's QPI interface speeds to 9.6GT/s.

Mark and Joel Make Autonomous Drones in Their Spare Time (Video) 15

from the when-a-drone-hits-your-eye-like-a-big-pizza-pie-that's-a-lawsuit dept.
Mark F. Brown and Joel Rozenweig build autonomous drones; that is, drones that don't need an operator every second. You tell the autonomous drone, "Pick up package # 941A at the loading dock and deliver it to 451 Bradbury St.' and off it goes. It's going to be a while yet before that happens, but one day....

Back in the present, dronemaking is still a hobby for Mark and Joel, something they do for fun after spending their workdays as software engineers at Intel. Joel says there is 'remarkably little' crossover between their jobs and their hobby, and that (so far) Intel has contributed little beyond some Edison modules (which you can buy for less than $50) and travel to the Embedded Linux Conference, where they gave a talk accompanied by these slides. NOTE: We have a little bonus for you today. We try to keep videos to 10 minutes or less, but we have no such constraints on transcript length. So if you want the 'full' version of this interview, please read the transcript.

Opportunity Rover Reaches Martian Day 4,000 of Its 90-Day Mission 109

Posted by Soulskill
from the awesome-engineers-doing-awesome-work dept.
An anonymous reader writes: Let's take a moment to appreciate the incredible engineering, scientific, and planning skill that went into the construction and deployment of the Opportunity rover. It landed on Mars with the goal of surviving 90 sols (Martian days), and it has just logged its 4,000th sol of harvesting valuable data and sending it back to us. The Planetary Society blog has posted a detailed update on Opportunity's status, and its team's plans for the future. The rover's hardware, though incredibly resilient, is wearing down. They reformatted its flash drive to block off a corrupted sector, and that solved some software problems that had cropped up. They're currently trying to figure out why the rover unexpectedly rebooted itself. Those events are incredibly dangerous to the rover's survival, so their highest priority right now is diagnosing that issue.

Fortunately, weather on Mars is good where the rover is, and it's still able to harvest upwards of 500 Watt-hours of energy from its solar panels. Opportunity recently completed a marathon on Mars and took an impressive picture of the Spirit of St. Louis crater, and the rover will soon be on its way to enormous clay deposits that could provide valuable information about where we can look for water when we eventually put people on Mars. As always, you can look through Opportunity's images at the official website.
