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.

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.

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.

Scientists Publish First Catalog Of All Proteins In Human Body
Every gene in our body has is meant to create proteins. The creation of the proteins is often instructed by the DNA, which makes their presence all the more intriguing. This is precisely why scientists are publishing the human proteome, a compilation of all the proteins in a human body.
The publication will be a result of the works of two teams of scientists. One of these teams studied samples from 17 organs of nine people, trying to discern different types of proteins. 72 scientists from all over the globe participated in this effort, resulting in the cataloging of proteins made by 17,294 genes, including 2535 such genes which were previously unknown or little known in the world of medical science.

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.

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.

Who is Peggy Whitson?
NASA astronaut Peggy Whitson, the only woman living onboard the International Space Station at the moment, is on track to break a big spaceflight record: at the end of April, she will have spent more cumulative hours in space than any other US astronaut. But now it looks like Whitson’s going to rack up even more flight time in lower Earth orbit than originally planned. NASA announced today that Whitson will be extending her stay on the ISS by an additional three months, adding even more hours to her record-breaking time in space.
Whitson launched to the ISS in November 2016 on a Russian Soyuz rocket, along with Russian cosmonaut Oleg Novitskiy and Thomas Pesquet of the European Space Agency. Their stay on the ISS, known as Expedition 51, was meant to last until June. That’s still true for Pesquet and Novitskiy, but Whitson will now come back sometime in September. Her trip back to Earth will be with NASA astronaut Jack Fischer and cosmonaut Fyodor Yurchikhin — two crew members who are slated to launch to the ISS later this month

“Shale 2.0”: Shale Drilling Turned From Art Into Science
Exxon Mobil, Royal Dutch Shell and Chevron plan to spend a combined $10 billion this year in American shale. If successful, they’ll scramble the U.S. energy business, boost American oil production, keep prices low, and steal influence from big producers. Furthermore, they are transforming shale drilling into a more economical operation. At Bongo 76-43, Shell is drilling five wells in a single pad for the first time, each about 20 feet apart, and is now able to drill 16 wells with a single rig every year, up from six in 2013.

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."
