An analysis by researchers at Bastille Networks indicates that your wireless mouse might provide an attacker with a route to get malware onto your machine, provided they’re within about 100 meters. They’ve dubbed this vulnerability “Mousejack.” The researchers tested many mice from manufacturers like Logitech, Dell, and Lenovo that operate over 2.4GHz wireless communications. This →
The name of the game in optical metasurfaces is shortening the wavelengths of light. This yields devices that can manipulate light for information processing and also reduce the bulk of the devices based on traditional optics. Metasurfaces have been pretty good at offering small, flat features, but the integrated metallic resonators they use to filter light according →
Physicists have succeeded in confirming one of the theoretical aspects of quantum physics: Subatomic objects switch between particle and wave states when observed, while remaining in a dual state beforehand. In the bizarre world of quantum mechanics, events rippling back in time may not seem that much stranger than things like “spooky action at a →
Did you know that black belts do not indicate ninja-level mastery, adding only a sprinkle of salt to fresh water does not make it boil quicker, and that sharks do get cancer? These are all part of the myths and misconceptions infographic created by London-based author, data-journalist and information designer David McCandless. http://www.iflscience.com/editors-blog/52-common-myths-and-misconceptions-debunked Posted from →

The RS-UV3 is a shot in the arm for amateur radio. The RS-UV3 lets you build your own Arduino- or Raspberry Pi–based radio. The US $90 RS-UV3 radio shield from HobbyPCB is an FM transceiver that’s welcoming by design and built for makers from the ground up. It’s not the only radio shield available for →
New research suggests that software piracy has a detrimental effect on the adoption of Linux desktop operating systems. Piracy is one of the reasons why Windows has been able to maintain its dominant market position, making open source alternatives “forgotten victims” of copyright infringement. https://torrentfreak.com/software-piracy-hurts-linux-adoption-research-finds-160221/ Posted from WordPress for Android →
Dr. Paul Kelley, a researcher at Oxford University, has scientifically corroborated the claim that nearly every worker to ever live has made: that it sucks to work before 10 AM. “Before the age of 55, the circadian rhythms of adults are completely out of sync with normal nine-to-five working hours, posing a “serious threat” to →
We have all heard about or seen on TV Alexander Stubb welcoming the last OECD report about Finland, and congratulating himself and the government on the support for OECDs to the Finnish government’s program. That is just a communication trick. because this optimistic is simply wrong http://finlandpolitics.org/2016/02/17/what-the-oecd-has-really-said-about-finlands-economy/ Posted from WordPress for Android →
