The space laboratory that China launched earlier this week has an atomic clock in it which is more accurate than the best timepiece operated by America's National Institute of Standards and Technology, according to Chinese engineers. The atomic called, dubbed CACS or Cold Atomic Clock in Space, will slow down by only one second in a billion years. In comparison, the NIST's F2 atomic clock, which serves as the United States' primary time and frequency standard, loses a second every 300 million years. From an RT report:"It is the world's first cold atomic clock to operate in space... it will have military and civilian applications," said Professor Xu Zhen from the Shanghai Institute of Optics and Fine Mechanics, who was involved in the CACS project. An atomic clock uses vibrations of atoms to measure time, which are very consistent as long as the atoms are held at constant temperature. In fact, since 1967 the definition of second has been "9,192,631,770 vibrations of a cesium-133 atom." In a cold atomic clock, the atoms are cooled down with a laser to decrease the effect of atom movement on the measurements. CACS goes even further and eliminates the pull of Earth's gravity by being based in orbit.Read Replies (0)

This week saw the first stable release of Android-x86 6.0 (marshmallow-x86) -- and a new version of Remix OS for PC, a PC-optimized version of Android. Slashdot reader prisoninmate quotes Softpedia: Android-x86 6.0 has been in the works since early this year, and it received a total of two RC (Release Candidate) builds during its entire development cycle, one in June and another in August. After joining the Remix OS team, Chih-Wei Huang now has all the reasons to update and improve its Android-x86 system for the latest Android releases. Therefore, as you might have guessed already, Android-x86 6.0 is the first stable version of the project to be based on Google's Linux kernel-based Android 6.0 Marshmallow mobile operating system, and includes the most recent AOSP (Android Open Source Project) security updates too. Under the hood, Android-x86 6.0 is using the long-term supported Linux 4.4.20 kernel with an updated graphics stack based on Mesa 12.0.2 3D Graphics Library, and offers support for Samsung's F2FS file system for SSD drives, better Wi-Fi support after resume and suspend, and initial HDMI audio support.Read Replies (0)

"If the PC is tampered with, it will trigger an alert and erase the PC's encryption key, making the data totally inaccessible." Last month Design SHIFT began crowdfunding an elaborate "open source, physically secure personal computer" named ORWL (after George Orwell). "Having exceeded its $25,000 funding goal on Crowd Supply, the super-secure PC is in production," reports PC World, in an article shared by Slashdot reader ogcricket about the device which tries to anticipate every possible attack:
The encryption key to the drive is stored on a security microcontroller instead of the drive... The ORWL's makers say the wire mesh itself is constantly monitored... Any attempts to trick, bypass, or short the wire mesh will cause the encryption key to be deleted. The unit's security processor also monitors movement, and a user can select a setting that will wipe or lock down the PC's data if it is moved to another location... The RAM is soldered to the motherboard and can't be easily removed to be read elsewhere...
Your ORWL unlocks by using a secure NFC and Bluetooth LE keyfob. Pressing it against the top of the ORWL and entering a password authenticates the user. Once the user has been authenticated, Bluetooth LE is then ensures that the user is always nearby. Walk away, and the ORWL will lock.Read Replies (0)

"Remember the San Bernardino killer's iPhone, and how the FBI maintained that they couldn't get the encryption key without Apple providing them with a universal backdoor?" Slashdot reader LichtSpektren quotes Bruce Schneier:
Many of us computer-security experts said that they were wrong, and there were several possible techniques they could use. One of them was manually removing the flash chip from the phone, extracting the memory, and then running a brute-force attack without worrying about the phone deleting the key. The FBI said it was impossible. We all said they were wrong. Now, Sergei Skorobogatov has proved them wrong.
Sergei's new paper describes "a real world mirroring attack on the Apple iPhone 5c passcode retry counter under iOS 9."
The process does not require any expensive and sophisticated equipment. All needed parts are low cost and were obtained from local electronics distributors. By using the described and successful hardware mirroring process it was possible to bypass the limit on passcode retry attempts... Although the process can be improved, it is still a successful proof-of-concept project.Read Replies (0)

An anonymous reader quotes a report from Los Angeles Times: 21st Century Fox on Friday filed a lawsuit against Netflix, accusing the streaming video giant of illegally recruiting two of its executives who were under contract. The suit, which was filed Friday in California Superior Court in Los Angeles, says Netflix engaged in a "brazen campaign to unlawfully target, recruit, and poach valuable Fox executives by illegally inducing them to break their employment contracts with Fox to work at Netflix." The lawsuit was sparked following the exits of two Fox executives: Marcos Waltenberg, who made the jump to Netflix earlier this year, previously worked as a marketing executive at Twentieth Century Fox Film; Tara Flynn, who made the move to Netflix just last week, had been the vice president of creative affairs at Fox 21 TV Studios. Fox alleges that Netflix pursued and hired the executives even though it knew they each had employment contracts that were still in effect, according to the complaint. The Century City-based studio is seeking an injunction to prevent Netflix from interfering with its employment contracts, as well as compensatory and punitive damages. A Netflix spokesperson said in a statement: "We intend to defend this lawsuit vigorously. We do not believe Fox's use of fixed term employment contracts in this manner are enforceable. We believe in employee mobility and will fight for the right to hire great colleagues no matter where they work."Read Replies (0)

An anonymous Slashdot reader quotes the Washington Post:
Less than two months after declaring the controversial F-35 Joint Strike Fighter ready for combat, the Air Force on Friday announced that it was temporarily grounding 15 of the jets after it discovered that insulation was "peeling and crumbling" inside the fuel tanks. The setback is the latest for the $400 billion system, the most expensive in the history of the Pentagon. The problem comes as the program, which for years faced billions of dollars in cost overruns and significant schedule delays, had begun to make strides.
The insulation problem affects a total of 57 aircraft, the Air Force said, 42 of which are still in production... In a statement, Lockheed Martin said that "the issue is confined to one supplier source and one batch of parts." It emphasized that "this is not a technical or design issue; it is a supply chain manufacturing quality issue..." It is unclear how long the aircraft would be grounded, how long the problem would take to fix or what the larger affect on the program would be.
âoeWhile nearing completion, the F-35 is still in development, and challenges are to be expected," said an Air Force spokeswoman, adding "The F-35 program has a proven track record of solving issues as they arise, and we're confident we'll continue to do so."Read Replies (0)
Pluto Is Emitting X-Rays

An anonymous reader quotes a report from Digital Trends: Scientists have noticed the tiny trans-Neptunium object emitting X-rays, which, if it is confirmed, is both a baffling and exciting discovery. Carey Lisse and Ralph McNutt from Johns Hopkins University Applied Physics Laboratory and a team of colleagues detected the X-rays by pointing the Chandra X-Ray Obervatory telescope in Pluto's direction four different times between February 2014 and August 2015. Seven photons of X-ray light were detected during these observations, confirming the team's hypothesis that the dwarf planet is detectable on the X-ray spectrum, potentially due to the presence of an atmosphere. Their findings have been published in the scientific journal Icarus. Why is this such a big deal? First of all, it would challenge what scientists have previously believed to be true of Pluto's nature. Until now, the popular description of the dwarf planet is as a tiny ball of frozen rock slowly meandering around the sun some 3.6-billion miles away. One of the possible explanations for why Pluto is emanating X-rays would be that the high energy particles emitted by the sun are stripping away and reacting with Pluto's atmosphere, producing the X-rays that are visible to Chandra. There are other potential explanations, such as haze particles in Pluto's atmosphere scattering the sun's X-rays are possible, though unlikely given the temperature of the X-rays observed. It is also possible that these X-rays are actually bright auroras produced by the atmosphere, but that would require Pluto to have a magnetic field -- something that would have been detected during New Horizon's flyby, yet no evidence of one was found.Read Replies (0)

An anonymous reader quotes a report from Washington Post: When the Arab Spring spread across the Middle East and North Africa, the internet was considered to have been one of the main facilitators of the revolutions, and while the Arab Spring has since become a source of frustration to many of those who fought for it, the assumption that the internet will facilitate future uprisings has rarely been questioned. A new study, however, now raises doubts about to what extent the internet plays a role in fostering democracy. In fact, it may make some people more equal than others. To voice discontent online, groups first need access to the internet, but too often, that is precisely what they lack, according to the report which was published by the academic journal Science. Those findings could force Western governments and nongovernmental organizations engaged in pro-democracy initiatives to rethink how they spread their message. Comparing the accessibility of internet in certain regions and taking into account the existence of minority communities, the authors found "a strong and persistent political bias in the allocation of internet coverage across ethnic groups worldwide [...] an effect that cannot be explained by economic or geographic factors." Around 500 minority groups worldwide were included in the study, with consistent findings of what the authors called "digital discrimination." The 10 worst-affected minorities mostly come from Russia and Malaysia, said researcher Nils B. Weidmann.Read Replies (0)

We've seen a number of entities announce plans to operate with 100% renewable energy over the years. Costa Rica, for example, has gone 76 straight days using 100% renewable electricity. General Motors is the latest company to release a roadmap to achieving 100% renewable energy. The catch? It won't be until 2050. CleanTechnica reports: American multinational General Motors, or GM, has committed to generating or sourcing 100% of the electricity for its operations across 59 countries from 100% renewable energy by 2050. GM made the announcement on Wednesday, revealing that it planned to generate or source all its electrical power needs for its 350 operations in 59 countries with 100% renewable energy such as wind, solar, and landfill gas, by 2050. In turn, the company has joined the 100% renewable energy campaign RE100, lending its considerable global business weight to an already important and successful campaign. "Establishing a 100% renewable energy goal helps us better serve society by reducing environmental impact," said Mary Barra, GM Chairman and CEO. "This pursuit of renewable energy benefits our customers and communities through cleaner air while strengthening our business through lower and more stable energy costs."Read Replies (0)

An anonymous reader quotes a report from BBC: An autistic man suspected of hacking into U.S. government computer systems is to be extradited from Britain to face trial, a court has ruled. Lauri Love, 31, who has Asperger's syndrome, is accused of hacking into the FBI, the U.S. central bank and the country's missile defense agency. Mr Love, from Stradishall, Suffolk, has previously said he feared he would die in a U.S. prison if he was extradited. Earlier, his lawyer said his alleged hacking had "embarrassed" U.S. authorities. Tor Ekeland said the U.S. government "had very, very bad security and these hacks utilized exploits that were publicly-known for months." Mr Love's lawyers said he could face up to 99 years in prison if convicted of the hacking offenses. Mr Love's defense team argues his depression and Asperger's syndrome mean he should not be sent abroad, but U.S. prosecutors say he is using his mental health issues as an excuse to escape justice.Read Replies (0)

Some of the United States' biggest cities have resorted to using dry ice to kill rats. Since dry ice (frozen carbon dioxide) turns into a gas, sanitation officials simply need to drop chunks of it into rat infested burrows and let science do the rest. Longtime Slashdot reader mi writes: USA Today reports: "Earlier this week, USA TODAY observed Chicago sanitation department workers at one of the city's oldest parks scoop chunks of smoking dry ice into a burrow before quickly covering the entry and exit holes with dirt and newspaper to stop any rats from escaping as the -109.3-degree Fahrenheit gas dissipated. Sanitation workers say they treat burrows during morning hours, when rats are less active and most likely to be huddled inside the burrows. The asphyxiated dead rats then decompose in place and out-of-sight of city denizens who count the disease-carrying vermin among the vilest of indignities of urban living. 'We are seeing 60% fewer burrows in areas where we are using the dry ice,' said Charles Williams, Chicago's streets and sanitation commissioner. 'It's more environmentally friendly, and it's very humane on the rodents as well.'" Humane or not, what is so especially "undignified" about rats? What makes them worse, than, for example, cats, deer or wild horses?Read Replies (0)

An anonymous reader quotes a report from Ars Technica: Yesterday, software developer John Brooks released what is clearly a work of pure love: the first update to an operating system for the Apple II computer family since 1993. ProDOS 2.4, released on the 30th anniversary of the introduction of the Apple II GS, brings the enhanced operating system to even older Apple II systems, including the original Apple ][ and ][+. Which is pretty remarkable, considering the Apple ][ and ][+ don't even support lower-case characters. You can test-drive ProDOS 2.4 in a Web-based emulator set up by computer historian Jason Scott on the Internet Archive. The release includes Bitsy Bye, a menu-driven program launcher that allows for navigation through files on multiple floppy (or hacked USB) drives. Bitsy Bye is an example of highly efficient code: it runs in less than 1 kilobyte of RAM. There's also a boot utility that is under 400 bytes -- taking up a single block of storage on a disk. The report adds: "In addition to the Bitsy Boot boot utility, the ProDOS 2.4 'floppy' includes a collection of utilities, including a MiniBas tiny BASIC interpreter, disk imaging programs to move files from physical floppies to USB and other disk storage, file utilities, and the 'Unshrink' expander for uncompressing files archived with Shrinkit."Read Replies (0)

An anonymous reader quotes a report from Motherboard: Typically, cops don't like talking about IMSI catchers, the powerful surveillance technology used to monitor mobile phones en masse. In a recent case, the New York Police Department (NYPD) introduced a novel argument for keeping mum on the subject: Asked about the tools it uses, it argued that revealing the different models of IMSI catchers the force owned would make the devices more vulnerable to hacking. The New York Civil Liberties Union (NYCLU), an affiliate of the ACLU, has been trying to get access to information about the NYPD's IMSI catchers under the Freedom of Information Law. These devices are also commonly referred to as "stingrays," after a particularly popular model from Harris Corporation. Indeed, the NYCLU wants to know which models of IMSI catchers made by Harris the police department has. "Public disclosure of this information, and the amount of taxpayer funds spent to buy the devices, directly advances the Freedom of Information Law's purpose of informing a robust public debate about government actions," the NYCLU writes in a court filing. The group has requested documents that show how much money has been spent on the technology. After the NYPD withheld the records, the FOI request was escalated to a lawsuit, which is where the NYPD's strange argument comes in (among others). "Public disclosure of the specifications of the CSS [cell site simulator] technologies in NYPD's possession from the Withheld Records would make the software vulnerable to hacking and would jeopardize NYPD's ability to keep the technologies secure," an affidavit from NYPD Inspector Gregory Antonsen, dated August 17, reads. Antonsen then imagines a scenario where a "highly sophisticated hacker" could use their knowledge of the NYPD's Stingrays to lure officers into a trap and ambush them.Read Replies (0)

Not long ago, Apple CEO Tim Cook explained why the company felt a need to remove the headphone jack from the new iPhones -- the iPhone 7 and iPhone 7 Plus. He said, "that jack takes up a lot of space in the phone, a lot of space. And there's a lot of more important things we can provide for the consumer than that jack." His colleague Phil Schiller cited "courage" for the same. As people learn to live in a world where they have to use a dongle to use their existing pair of headphones, gadget repair community iFixit found today that Apple isn't really using that "extra space" it got after getting rid of the headphone jack. BusinessInsider reports: "In place of the headphone jack, we find a component that seems to channel sound from outside the phone into the microphone... or from the Taptic Engine out," they write. Yep -- in the place where the headphone jack used to be there's a piece of molded plastic. "No fancy electronics here, just some well-designed acoustics and molded plastic," iFixit writes.iFixit adds, "Closer inspection shows a new, second lower speaker grille that leads ... nowhere? Interesting." Update: 09/16 21:21 GMT by M : Apple says it's a "barometric vent." The Verge reports: Apparently adding all the waterproofing to the iPhone 7 and 7 Plus meant that it was more of a sealed box, and so to be able to have an accurate and working barometer, Apple used that space. The barometer is the thing that allows a phone to measure altitude, and Apple points out that on the iPhone 7 it can measure even minor changes like climbing a flight of stairs.Read Replies (0)
