Submission + - Quantum Microscope 3D Simulator of Atoms Open Sourced (energywavetheory.com)

atomicphysics writes: The Quantum Microscope add-on for Blender has been released to open source. The free-to-download 3D simulator provides accurate modeling of molecules, atoms and their subatomic particles by using classical, Newtonian physics.

A contest begins September 1, 2020 for developers to enhance the add-on, or create a new simulator meeting project requirement to use classical physics for the quantum realm, with at least $15,000 in prizes being awarded over the next year.

Submission + - Researchers create patterned stickers that can confuse AI image recognition (techcrunch.com)

amxcoder writes: Researchers at Google were able to create little stickers with 'psychedelic' looking patters on them that could trick computer AI image classifying algorithms into mis-classifying images of objects that it would normally be able to recognize. The images on the stickers were created by the researchers using knowledge of features and shapes, patterns, and colors that the image recognition algorithms look for and focus on. The patterned stickers work by tricking the image recognition algorithm into focusing on, and studying the little pattern on the small sticker and ignoring the rest of the image, including the actual object in the picture. Image recognition algorithms work by attempting to weigh importance to parts of an image as higher than other parts so it can determine the subject object in the image. These stickers were created so that the algorithm finds them 'more interesting' than the rest of the image and will focus most of it's attention on analyzing the pattern and giving the rest of the image content a lower importance, thus ignoring it or confusing it.

Submission + - NASA Launches a Mission To Study the Border of Earth and Space (arstechnica.com)

An anonymous reader writes: A new NASA mission, the first to hitch a ride on a commercial communications satellite, will examine Earth's upper atmosphere to see how the boundary between Earth and space changes over time. GOLD stands for Global-scale Observations of the Limb and Disk, and the mission will focus on the temperature and makeup of Earth's highest atmospheric layers. Along with another upcoming satellite, called ICON, GOLD will examine how weather on Earth — and space weather caused by the sun — affects those uppermost layers. GOLD, which will inspect the ultraviolet radiation that the upper atmosphere releases, will also be the first to take comprehensive records of that atmospheric layer's temperature. The satellite carrying GOLD will orbit 22,000 miles (35,400 kilometers) above Earth in a geostationary orbit, which means GOLD will stay fixed with respect to Earth's surface as the satellite orbits and the world turns. GOLD will pay particularly close attention to Earth's thermosphere, which is the gas that surrounds the Earth higher than 60 miles (97 km) up, and the layer called the ionosphere, which forms as radiation from the sun strips away electrons from particles to create charged ions. And although solar flares and other interactions on the sun do have a strong impact on those layers, scientists are learning that Earth's own weather has an impact on the layers, too.

Submission + - Linus Torvalds says Intel needs to admit it has issues with CPUs (itwire.com)

troublemaker_23 writes: Linux creator Linus Torvalds has had some harsh words for Intel in the course of a discussion about patches for two bugs that were found to affect most of the company's processors. Two flaws — dubbed Meltdown and Spectre — were revealed this week in Intel processors made since 1995 and companies have been hustling to offer fixes and workarounds.

Submission + - The FCC Is Preparing To Weaken the Definition of Broadband (dslreports.com)

An anonymous reader writes: Under Section 706 of the Telecommunications Act, the FCC is required to consistently measure whether broadband is being deployed to all Americans uniformly and "in a reasonable and timely fashion." If the FCC finds that broadband isn't being deployed quickly enough to the public, the agency is required by law to "take immediate action to accelerate deployment of such capability by removing barriers to infrastructure investment and by promoting competition in the telecommunications market." Unfortunately whenever the FCC is stocked by revolving door regulators all-too-focused on pleasing the likes of AT&T, Verizon and Comcast — this dedication to expanding coverage and competition often tends to waver.

What's more, regulators beholden to regional duopolies often take things one-step further — by trying to manipulate data to suggest that broadband is faster, cheaper, and more evenly deployed than it actually is. We saw this under former FCC boss Michael Powell (now the top lobbyist for the cable industry), and more recently when the industry cried incessantly when the base definition of broadband was bumped to 25 Mbps downstream, 4 Mbps upstream. We're about to see this effort take shape once again as the FCC prepares to vote in February for a new proposal that would dramatically weaken the definition of broadband. How? Under this new proposal, any area able to obtain wireless speeds of at least 10 Mbps down, 1 Mbps would be deemed good enough for American consumers, pre-empting any need to prod industry to speed up or expand broadband coverage.

Why would the driver have to consent? The drive for "public security" has already diminished our rights to the point that as soon as the officer states he 'smelled weed', he has all the consent he needs. Maybe you need to take a look at reality and hopefully begin to understand the severe slope we're already sliding down. What's next? Paying kids with new uniforms to turn in their parents for cussing?

Comment The question is, "What is Amateur Radio" (Score 2) 371

Are we an Emergency Service? No - we are not. That is what part 90 is for.

We are hobbyist, enthusiasts that practice the radio art and sciences. As such, we develop the skills and methods to make things work, when all else fails.

We fill in, when asked, when established systems fail. We are not a "First Responder" that jumps into any and every situation with our "magic" HTs to save the day.

If you want to be part of an EmComm organization, join one - they have their own radio service under part 90 rules. They use encryption there - and it works well.

Thankfully, the public communications community has noticed when things have gone bad and we've stepped in to help. They've evolved their systems to be more robust and survive events. No, they're not perfect and there will be opportunity to help out in the future. But, we provide that help out of civic duty. Not as an EmComm service.

Allowing encryption on the Amateur Bands will further dilute the separation between our hobbyest, experimental service and established EmComm services. When those EmComm service start asking for more bandwidth to support their growth - where do you think they're going to look? If we're already providing EmComm services - predeployed, dedicated, secure encrypted, agency specific communications - what shouldn't they have our bands?

Submission + - FDA: Software Failure Behind 24% Of Medical Device Recalls (threatpost.com)

chicksdaddy writes: "Software failures were behind 24 percent of all the medical device recalls in 2011, according to data from the U.S. Food and Drug Administration's (FDA's) Office of Science and Engineering Laboratories (OSEL).
The absence of solid architecture and "principled engineering practices" in software development affects a wide range of medical devices, with potentially life-threatening consequences, the FDA warned. In response, FDA told Threatpost that it is developing tools to disassemble and test medical device software and locate security problems and weak design."
