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.

America Begins Airport Tests of Technology To Detect Drones and 'Mitigate Potential Safety Risks Posed' (engadget.com) 36

To address the possibility of drone-flying near airports, America's Federal Aviation Administration "will be testing at least 10 technologies and systems," reports Engadget, "developed not just to detect unmanned aerial systems, but also to mitigate the potential safety risks they pose." The first tests will be conducted at FAA's William J. Hughes Technical Center, which is right next to the Atlantic City International Airport in New Jersey. After that, the agency expects to expand its tests to four additional airports in the U.S. It has yet to choose those airports, and it may also still be finalizing the list of technologies it's testing: The FAA is asking interested companies working on drone detection systems to respond to its announcement within 45 days.

23-Million-Year-Old Fossilized Leaves Offer New Insight Into Global Warming (upi.com) 37

UPI reports: The links between rising carbon dioxide levels, global warming and greening trends have been confirmed by fossilized leaves from a 23 million-year-old forest... Scientists previously postulated that ancient increases in atmospheric CO2 during the early Miocene allowed plants to perform photosynthesis more efficiently. But the latest research, published Thursday in the journal Climate of the Past, is the first to confirm the link between CO2 and greening in the fossil record...

Lab experiments have shown increases in CO2 can boost photosynthesis, and recent satellite surveys suggest rising CO2 levels are responsible for greening patterns across the planet, including Arctic and drylands ecosystems. The latest research suggests that greening trends are likely to continue as CO2 levels approach those recorded during ancient period of warming... According to the new study, increases in photosynthesis rates won't be able to keep up with current rates of human-caused carbon emissions. In addition, previous studies suggest increases in rates of photosynthesis can prevent staple crops from absorbing calcium, iron, zinc and other minerals important for human health....

By comparing the fossilized leaf structures, including microscopic veins, stomata and pores, to those of modern leaves, researchers designed a model to more accurately predict CO2 levels... "It all fits together, it all makes sense," said study co-author William D'Andrea, a paleoclimate scientist at Lamont-Doherty. "This should give us more confidence about how temperatures will change with CO2 levels."

Comment Re:Typical California behavior (Score 1) 279

The idea is to pick a time zone and stick with it. Nobody gives 2 craps whether it is DST or standard, just stick with it. For me personally, DST year-round "feels" more normal, so I'd be happy sticking with DST instead of just changing time zones completely.

Either way, we ought to pick one and stick with it. The changing back and forth is stupid.

Comment Can't force me (Score 1) 94

Microsoft can't and won't force me to use any version of skype. After MS bought skype and made some UI changes that made it harder to use, I just switched to facetime. "Problem" solved. Even my Mom is getting an iphone, in part so she can use facetime with everyone else who has ditched skype after MS ruined the UI.

Skype circa 2011 was pretty useable. It's been destroyed since then by UI mismanagement. I still prefer windows over apple OS and I use a windows computer instead of a mac, but for video chat and conferencing I've gone completely to facetime for no reason other than the skype UI has been wrecked since MS bought it.

Forcing users to "upgrade" to their latest crummy version is just one more push to switch services. There are plenty of alternatives.

Comment Hostile management (Score 1) 540

Hostile management, 99% of the reason I left. Union contract had been up for renegotiation for 2 years. Company fouled up the schedule then blamed the union for an illegal work slowdown, a completely fabricated charge, and sued us. The judge ruled while the union lawyer was still en-route to the courtroom, more proof it was a setup.

3 months later the company realized how horrible a mistake they had made when they lost 40 million dollars (or more) and had to report to the shareholders that they couldn't follow company growth plans because guess what - they didn't have a contract after 2 years. Almost immediately the company agreed to the union proposed payscale but by that time it was far too little too late, the company had already proven itself utterly untrustworthy and hostile.

My new job required an initial pay cut, has nearly identical long-term income potential, and is harder work. But my new company isn't suing me over a pretend "illegal work action" so it's much better.

The money isn't everything.

Comment Re:Yes.... (Score 2) 381

Yes but. I used to declare variables overly large as a kludge to help out when error-trapping was consuming too much time and I knew that the compiler wasn't good with overflows. So I'd do input error checking up to the point where it started to take too much time, then declare a variable larger than reasonable input would be, and then attempt to trap and reject input at a length between reasonable input values and the declared variable size. Declaring a variable just larger than the input buffer was one specific way to address attempts to force overflows through buffer overruns. Yes it was a horrible kludge and can't survive any sort of dedicated attack, but it served to deter casual probes looking for exploitable boundary condition errors.

Of course the better answer is to not use an OS and compiler that sucks so bad that the basic io buffers and basic overflows are exploitable, but sometimes you gotta use what you have.

Comment Just another way to vandalize stuff (Score 4, Insightful) 243

This is just another way to vandalize stuff. I owned a far cheaper version of this 30 years ago. Its called a baseball bat. Before that, I had a tack-hammer. My ancestors had a version too, but they called it a "brick". Even earlier versions were called "rocks".

If we're lucky, cities will start passing ordinances to make mere possession of these a crime, since there is no legal purpose for these.
