It's such a big task, in fact, that DeepMind and Blizzard are including "mini-games" in the release, which break down different subtasks into "manageable chunks," including teaching agents to master tasks like building specific units, gathering resources, or moving around the map. The hope is that compartmentalizing these areas of play will allow testing and comparison of techniques from different researchers on each, along with refinement, before their eventual combination in complex agents that attempt to master the whole game.
Mortality trends are only a small piece of the calculation companies make when estimating what they'll owe retirees, and indeed, other factors actually led Lockheed's pension obligations to rise last year. Variables such as asset returns, salary levels, and health care costs can cause big swings in what companies expect to pay retirees. The fact that people are dying slightly younger won't cure corporate America's pension woes -- but the fact that companies are taking it into account shows just how serious the shift in America's mortality trends is.
The plaintiffs argue that Disney and its partners violated COPPA, the Children's Online Privacy Protection Act, a federal law designed to protect the privacy of children on the Web. The lawsuit, filed in U.S. District Court for the District of Northern California, seeks an injunction barring the companies from collecting and disclosing the data without parental consent, as well as punitive damages and legal fees. The lawsuit alleges that Disney allowed the software companies to embed trackers in apps such as "Disney Princess Palace Pets" and "Where's My Water? 2." Once installed, tracking software can then "exfiltrate that information off the smart device for advertising and other commercial purposes," according to the suit. Disney should not be using those software development companies, said Jeffrey Chester, the executive director of the Center for Digital Democracy. "These are heavy-duty technologies, industrial-strength data and analytic companies whose role is to track and monetize individuals," Chester said. "These should not be in little children's apps." Disney responded to the lawsuit, saying: "Disney has a robust COPPA compliance program, and we maintain strict data collection and use policies for Disney apps created for children and families. The complaint is based on a fundamental misunderstanding of COPPA principles, and we look forward to defending this action in court."
The FCC found during George W. Bush's presidency that fast Internet service was being deployed in a reasonable and timely fashion. But during the Obama administration, the FCC determined repeatedly that broadband isn't reaching Americans fast enough, pointing in particular to lagging deployment in rural areas. These analyses did not consider mobile broadband to be a full replacement for a home (or "fixed") Internet connection via cable, fiber, or some other technology. Last year, the FCC updated its analysis with a conclusion that Americans need home and mobile access. Because home Internet connections and smartphones have different capabilities and limitations, Americans should have access to both instead of just one or the other, the FCC concluded under then-Chairman Tom Wheeler. The report goes on to add that with Republican Ajit Pai as chairman of the FCC, "the FCC seems poised to change that policy by declaring that mobile broadband with speeds of 10Mbps downstream and 1Mbps upstream is all one needs." Furthermore, "In doing so, the FCC could conclude that broadband is already being deployed to all Americans in a reasonable and timely fashion, and thus the organization would take fewer steps to promote deployment and competition."
Cyber specialists say the problem with GPS and other Global Navigation Satellite Systems (GNSS) is their weak signals, which are transmitted from 12,500 miles above the Earth and can be disrupted with cheap jamming devices that are widely available. Developers of eLoran - the descendant of the loran (long-range navigation) system created during World War II - say it is difficult to jam as the average signal is an estimated 1.3 million times stronger than a GPS signal. To do so would require a powerful transmitter, large antenna and lots of power, which would be easy to detect, they add.
What interests me is the possibility that black holes of all kinds -- and particularly primordial black holes -- are so commonplace that they may be all that's required to explain the effects of "dark matter." Dark matter, which, according to current models, makes up some 26% of the mass of our Universe, has been firmly established as real, both by calculation of the gravity necessary to hold spiral galaxies like our own together, and by direct observation of gravitational lensing effects produced by the "empty" space between recently-collided galaxies. There's no question that it exists. What is unknown, at this point, is what exactly it consists of.
The leading candidate has, for decades, been something called WIMPs (Weakly-Interacting Massive Particles), a theoretical notion that there are atomic-scale particles that interact with "normal" baryonic matter only via gravity. The problem with WIMPs is that, thus far, not a single one has been detected, despite years of searching for evidence that they exist via multiple, multi-billion-dollar detectors.
With the recent publication of a study of black hole populations in our galaxy (article paywalled, more layman-friendly press release at Phys.org) that indicates there may be as many as 100 million stellar-remnant-type black holes in the Milky Way alone, the question arises, "Is the number of primordial and stellar-remnant black holes in our Universe sufficient to account for the calculated mass of dark matter, without having to invoke WIMPs at all?"
I don't personally have the mathematical knowledge to even begin to answer that question, but I'm curious to find out what the professional cosmologists here think of the idea.
