Working with Twitter and Double Robotics, The Post’s robot will provide a live stream of delegates and politicians in Cleveland and Philadelphia via Twitter’s app, Periscope, giving users a guided tour of the convention site and letting them ask questions about the convention experience via Periscope chat.
PC shipments return to growth in the US
While we’re still waiting for worldwide shipments to go positive, both IDC and Gartner report that PC shipments in the US have increased for the first time in more than a year. IDC reports that shipments have increased by 4.9 percent, and Gartner says they’ve risen by 1.4 percent.

Worldwide, PC shipments are still on a decline. Gartner estimates a 5.2 percent drop, and IDC calculates around a 4.5 percent decrease in shipments.
Could antivirus software make your computer less safe?
Increasingly, attacks focus on social engineering or phishing that lures users onto compromised websites that can steal information or serve ransomware.
Those websites are so short-lived that antivirus software often doesn’t update fast enough to recognize them, Sjouwerman added.

How China Took Center Stage in Bitcoin’s Civil War
Yet despite the talk of a borderless currency, a handful of Chinese companies have effectively assumed majority control of the Bitcoin network. They have done so through canny investments and vast farms of computer servers dispersed around the country. The American delegation flew to Beijing because that was where much of the Bitcoin power was concentrated.

Mr. Ng, 36, said he had become an expert in finding cheap energy, often in places where a coal plant or hydroelectric dam was built to support some industrial project that never happened. The Bitcoin mining machines in his facilities use about 38 megawatts of electricity, he said, enough to power a small city.
Lincoln Laboratory demonstrates highly accurate vehicle localization under adverse weather conditions
The reliance on static underground features is LGPR’s advantage as a complement to other localization methods, even in fair weather conditions. The use of a subsurface map reduces the need for continual modifications to high-resolution road maps. Fusing GPS, lidar, camera, and LGPR results yields a system that can accurately localize even when one of the sensing modes fails. This “fail-safe” capability will be necessary to the development of dependable autonomous vehicles that can handle demanding ground environments.
How to Compromise the Enterprise Endpoint
Because Symantec uses a filter driver to intercept all system I/O, just emailing a file to a victim or sending them a link to an exploit is enough to trigger it – the victim does not need to open the file or interact with it in anyway. Because no interaction is necessary to exploit it, this is a wormable vulnerability with potentially devastating consequences to Norton and Symantec customers.
An attacker could easily compromise an entire enterprise fleet using a vulnerability like this. Network administrators should keep scenarios like this in mind when deciding to deploy Antivirus, it’s a significant tradeoff in terms of increasing attack surface.

World’s First 1,000-Processor Chip
Each processor core can run its own small program independently of the others, which is a fundamentally more flexible approach than so-called Single-Instruction-Multiple-Data approaches utilized by processors such as GPUs; the idea is to break an application up into many small pieces, each of which can run in parallel on different processors, enabling high throughput with lower energy use, Baas said.
Because each processor is independently clocked, it can shut itself down to further save energy when not needed, said graduate student Brent Bohnenstiehl, who developed the principal architecture.
People are spending much less time on social media apps
In the U.S. — typically social media’s most lucrative market — Instagram use was down 36.2 percent, Twitter was down 27.9 percent, Snapchat was down 19.2 percent and Facebook fell 6.7 percent

The Ken Thompson Hack
Ken describes how he injected a virus into a compiler. Not only did his compiler know it was compiling the login function and inject a backdoor, but it also knew when it was compiling itself and injected the backdoor generator into the compiler it was creating. The source code for the compiler thereafter contains no evidence of either virus.
Ken wrote, In demonstrating the possibility of this kind of attack, I picked on the C compiler. I could have picked on any program-handling program such as an assembler, a loader, or even hardware microcode. As the level of program gets lower, these bugs will be harder and harder to detect. A well installed microcode bug will be almost impossible to detect.

Flat lens promises possible revolution in optics
The lens is quite unlike the curved disks of glass familiar from cameras and binoculars. Instead, it is made of a thin layer of transparent quartz coated in millions of tiny pillars, each just tens of nanometres across and hundreds high.
Singly, each pillar interacts strongly with light. Their combined effect is to slice up a light beam and remould it as the rays pass through the array

“The quality of our images is actually better than with a state-of-the-art objective lens. I think it is no exaggeration to say that this is potentially revolutionary.”
