World's largest radio telescope completed in China
China on Sunday hoisted the final piece into position on what will be the world's largest radio telescope, which it will use to explore space and help in the hunt for extraterrestrial life, state media said.
The Five-hundred-metre Aperture Spherical Telescope, or FAST, is the size of 20 Canadian football fields and has been hewed out of a mountain in the poor southwestern province of Guizhou.
China will relocate 9,000 people to build world's biggest radio telescope
Scientists will now start debugging and trials of the telescope, Zheng Xiaonian, deputy head of the National Astronomical Observation under the Chinese Academy of Sciences, which built the telescope, told the official Xinhua news agency.
"The project has the potential to search for more strange objects to better understand the origin of the universe and
boost the global hunt for extraterrestrial life," the report paraphrased Zheng as saying.

That Insane, $81M Bangladesh Bank Heist? Here’s What We Know
WHEN REPORTS SURFACED in February of a spectacular bank hack that sucked $81 million from accounts at Bangladesh Bank in just hours, news headlines snickered over a typo that prevented the hackers from stealing the full $1 billion they were after.
Last week the snickering stopped with new reports that the hackers struck a second bank, and possibly others—though authorities won’t say if those heists were equally successful. Bank hacks have traditionally focused on stealing the login credentials of bank account holders—either individuals or small businesses. Billions have been stolen successfully in this way. But the hacks in this case targeted the banks themselves and focused on subverting their SWIFT accounts, the international money transfer system that banks use to move billions of dollars daily between themselves.
As details continue to trickle out about how the heists unfolded, here’s a look at what we do and don’t know so far.
What is SWIFT?
SWIFT stands for the Society for Worldwide Interbank Financial Telecommunication and is a consortium that operates a trusted and closed computer network for communication between member banks around the world. The consortium, which dates back to the 1970s, is based in Belgium and is overseen by the National Bank of Belgium and a committee composed of representatives from the US Federal Reserve, the Bank of England, the European Central Bank, the Bank of Japan and other major banks. The SWIFT platform has some 11,000 users and processes about 25 million communications a day, most of them money transfer transactions. Financial institutions and brokerage houses that use SWIFT have codes that identify each institution as well as credentials that authenticate and verify transactions.

Ransomware-fighting coalition adds members and decryption tools By @lconstantin from @Computerworld
The No More Ransom project, a coalition of law enforcement and security companies, has expanded with 30 new members and added 32 new decryption tools for various ransomware variants.
The project, which consists of a website dedicated to fighting ransomware, was originally launched by Europol’s European Cybercrime Centre in partnership with the National High Tech Crime Unit of the Netherlands police, Kaspersky Lab, and Intel Security.
The website has a tool that allows users to determine which type of ransomware has affected their files but also contains general information about ransomware, prevention advice, and instruction on reporting incidents to law enforcement.
One section of the website is dedicated to decryption tools that participating companies have developed for various ransomware variants. The creation of such tools is possible because some ransomware programs have flaws in their cryptographic implementations.

Gravitational Waves Detected 100 Years After Einstein's Prediction
LIGO Opens New Window on the Universe with Observation of Gravitational Waves from Colliding Black Holes
WASHINGTON, DC/Cascina, Italy
For the first time, scientists have observed ripples in the fabric of spacetime called gravitational waves, arriving at the earth from a cataclysmic event in the distant universe. This confirms a major prediction of Albert Einstein’s 1915 general theory of relativity and opens an unprecedented new window onto the cosmos.
Gravitational waves carry information about their dramatic origins and about the nature of gravity that cannot otherwise be obtained. Physicists have concluded that the detected gravitational waves were produced during the final fraction of a second of the merger of two black holes to produce a single, more massive spinning black hole. This collision of two black holes had been predicted but never observed.
The gravitational waves were detected on September 14, 2015 at 5:51 a.m. Eastern Daylight Time (09:51 UTC) by both of the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA. The LIGO Observatories are funded by the National Science Foundation (NSF), and were conceived, built, and are operated by Caltech and MIT. The discovery, accepted for publication in the journal Physical Review Letters, was made by the LIGO Scientific Collaboration (which includes the GEO Collaboration and the Australian Consortium for Interferometric Gravitational Astronomy) and the Virgo Collaboration using data from the two LIGO detectors.
Based on the observed signals, LIGO scientists estimate that the black holes for this event were about 29 and 36 times the mass of the sun, and the event took place 1.3 billion years ago. About 3 times the mass of the sun was converted into gravitational waves in a fraction of a second—with a peak power output about 50 times that of the whole visible universe. By looking at the time of arrival of the signals—the detector in Livingston recorded the event 7 milliseconds before the detector in Hanford—scientists can say that the source was located in the Southern Hemisphere.
According to general relativity, a pair of black holes orbiting around each other lose energy through the emission of gravitational waves, causing them to gradually approach each other over billions of years, and then much more quickly in the final minutes. During the final fraction of a second, the two black holes collide into each other at nearly one-half the speed of light and form a single more massive black hole, converting a portion of the combined black holes’ mass to energy, according to Einstein’s formula E=mc2. This energy is emitted as a final strong burst of gravitational waves. It is these gravitational waves that LIGO has observed.
The existence of gravitational waves was first demonstrated in the 1970s and 80s by Joseph Taylor, Jr., and colleagues. Taylor and Russell Hulse discovered in 1974 a binary system composed of a pulsar in orbit around a neutron star. Taylor and Joel M. Weisberg in 1982 found that the orbit of the pulsar was slowly shrinking over time because of the release of energy in the form of gravitational waves. For discovering the pulsar and showing that it would make possible this particular gravitational wave measurement, Hulse and Taylor were awarded the Nobel Prize in Physics in 1993.
The new LIGO discovery is the first observation of gravitational waves themselves, made by measuring the tiny disturbances the waves make to space and time as they pass through the earth.
“Our observation of gravitational waves accomplishes an ambitious goal set out over 5 decades ago to directly detect this elusive phenomenon and better understand the universe, and, fittingly, fulfills Einstein’s legacy on the 100th anniversary of his general theory of relativity,” says Caltech’s David H. Reitze, executive director of the LIGO Laboratory.

We’re building a world-size robot. How are we going to control it? Recommended by @jcentv
Last year, on October 21, your digital video recorder — or at least a DVR like yours — knocked Twitter off the internet. Someone used your DVR, along with millions of insecure webcams, routers, and other connected devices, to launch an attack that started a chain reaction, resulting in Twitter, Reddit, Netflix, and many sites going off the internet. You probably didn’t realize that your DVR had that kind of power. But it does.

In pictures: building the world's largest container ship by @WiredUK
Okpo, a port in South Korea, is home to Daewoo Shipbuilding and Marine Engineering, a company constructing the world's largest model of ship -- 12 at a time. "The place is mind-blowing," says photographer Alastair Phillip Wiper, who visited the shipyard for Wired on the eve of the departure of the ninth Triple-E class container vessel, the Matz Maersk. "This is just a small part of what they're doing. They have 46,000 people building around 100 vessels -- and everywhere you look there's some surreal part of a ship that's just about recognisable as something that should be underwater."
Twenty Triple-E class container ships have been commissioned by Danish shipping company Maersk Lines for delivery by 2015. The vessels will serve ports along the northern-Europe-to-Asia route, many of which have had to expand to cope with the ships' size. "You don't feel like you're inside a boat, it's more like a cathedral,"
Wiper says. "Imagine this space being full of consumer goods, and think about how many there are on just one ship. Then think about how many are sailing round the world everyday. It's like trying to think about infinity."

Developing a Two-Way Radio on a Single Chip By Peter Brown IEEE
In order to separate the signals, Alyosha Molnar, associate professor of electrical and computer engineering (ECE) at Cornell, created a series of six subtransmitters all hooked into an artificial transmission line. Each sends a signal at regular intervals so that they combine to produce a radio frequency signal in the forward direction at the antenna port. At the same time cancelling out at the receive port.
Researchers say the programmability of the individual subtransmitters allows for simultaneous summation and cancellation to be tuned across a wide range of frequencies and to adjust the signal strength at the antenna.
The antenna is put at one end and the amplified signal goes out of the antenna and the receiver at the other end where the nulling happens. The receiver sees the antenna through this wire, the transmission line, but the transmit signal goes unnoticed because it is cancelled out at the end.

What is 32-bit and 64-bit? by @TechAdvisorUK
PCs, laptops, Macs, Windows, phones and tablets - everything is 64-bit these days. Even some smartphones are 64-bit.
The main reason for the switch from 32-bit is to get past the limit on the amount of memory a 32-bit processor can access.
What is 32-bit and 64-bit?
Put simply, 32-bit is shorthand for a 32-bit number. This number contains 32 bits (binary digits) which are either 0 or 1. And example could be 10101010101010101010101010101010.
A 32-bit processor is - by definition - capable of dealing with instructions and referencing memory locations of 32-bits.

SpaceX is saving a ton of money by re-using Falcon 9 rockets
SpaceX is deep into the development of reusable rockets to slash launch costs for future missions, so one has to wonder how much its historic SES-10 mission saved. At the 33rd Space Symposium in Colorado, SpaceX President Gwynne Shotwell has revealed that the company spent "substantially less than half" the cost of a new first stage for the Falcon 9 reflight. While she didn't mention specific figures, that means huge savings, since the rocket's first stage accounts for around 75 to 80 of its total cost.
Shotwell said the private space corporation managed to save money even though it did a lot of work examining and refurbishing the flight-proven booster. SpaceX expects those cost savings to grow, since they won't do as much work on future recovered rockets as they did for the SES-10 launch.

Next step toward driverless cars: Tesla updates Autopilot
Speed caps are being raised for the autopilot function in newer Tesla cars, from 55 mph to 80 mph, in the form of new software that the company has started streaming into its vehicles.
The software update, called Autopilot 8.1, lets the cars pretty much drive themselves on highways up to the posted speed limit, or a maximum of 80.
The cars will stay in their lanes, turn around curves without driver intervention, and will pass vehicles automatically with a flick of the turn signal.
Human drivers are warned to pay attention, and the system will send warnings if hands aren’t placed on the steering wheel periodically, and the car will slow down and stop if the human fails to comply.
Tesla cars have had Autopilot for years but new models began being fitted with an expanded set of sensor hardware last October. The 55 mph Autopilot speed cap was placed on those cars, which Autopilot 8.1 lifts with its updates that started rolling out on Wednesday.

The Pentagon operates the oldest computer program still in use – from 1958
In 1958, the DoD’s first contracting software was launched, using an early computer language called COBOL. As of 2017, that software still manages Pentagon contracts.
According to Technology Review, the program known as MOCAS, Mechanization of Contract Administration Services, began its life on punchcards. Eventually it was updated to green screened, terminal-style computers.
Though a new-looking graphic interface often replaces the antiquated green text prompts, the insides are still very much the same. A series of new additions and plug-and-play storage devices hides an eight-gigabyte RAM system that manages $1.3 trillion in Pentagon contracting.
The reason the system was never replaced is due to the fact that its replacement would have to immediately take over the entire system as a whole to ensure that no contract — and none of the money — is lost in the transition.
