Comment We understand the "squirrel problem" (Score 4, Informative) 129

Problems like this have existed for decades or more and we know how to prevent it.

It's a business decision whether to invest in prevention, mitigation, both, or neither.

The "foreign government cyber-warfare" problem is less well-understood and is ever-evolving.

For what it's worth, most "mother nature" problems can be handled by having adequate redundancy and/or backup systems and, for most users, having an expected service level that allows for the grid (or internet, or other utility) to be offline for several seconds at a time while backup systems kick in. A state-level attacker is likely to be aware of the backup systems and attack both simultaneously.

Submission + - Humans, not climate change, wiped out Australian megafauna (phys.org)

schwit1 writes: New evidence involving the ancient poop of some of the huge and astonishing creatures that once roamed Australia indicates the primary cause of their extinction around 45,000 years ago was likely a result of humans, not climate change.

Led by Monash University in Victoria, Australia and the University of Colorado Boulder, the team used information from a sediment core drilled in the Indian Ocean off the coast of southwest Australia to help reconstruct past climate and ecosystems on the continent. The core contains chronological layers of material blown and washed into the ocean, including dust, pollen, ash and spores from a fungus called Sporormiella that thrived on the dung of plant-eating mammals, said CU Boulder Professor Gifford Miller.

Miller, who participated in the study led by Sander van der Kaars of Monash University, said the sediment core allowed scientists to look back in time, in this case more than 150,000 years, spanning Earth's last full glacial cycle. Fungal spores from plant-eating mammal dung were abundant in the sediment core layers from 150,000 years ago to about 45,000 years ago, when they went into a nosedive, said Miller, a professor in the Department of Geological Sciences.

"The abundance of these spores is good evidence for a lot of large mammals on the southwestern Australian landscape up until about 45,000 years ago," he said. "Then, in a window of time lasting just a few thousand years, the megafauna population collapsed."

Submission + - France to review food whitener additive, titanium dioxide, for health risks (reuters.com)

Eloking writes: The French government has ordered a review of the safety of titanium dioxide as a food additive after a scientific study released on Friday found health effects in animals that consumed the substance.

Titanium dioxide is widely used in industry as a whitener, notably for paint. It is an ingredient in some foods such as sweets and known as additive E171.

France's National Institute for Agricultural Research (INRA) and partners in a study on oral exposure to titanium dioxide had shown for the first time that E171 crosses the intestine wall in animals to reach other parts of the body, INRA said.

People are afraid of our legal system, and things are usually about making sure you can defend yourself against a lawsuit.
I had a friend who got a million dollar umbrella insurance policy when he put in a pool - just in case of a tragedy where a neighborhood kid drowned, he didn't want to be sued. The fact that you and a lot of others probably think "that's not a bad idea" means that lawyers have weaseled their way so deeply into our society that it's now the default behavior.

Just think about that. And watch things in your daily life. Our legal system is built to sustain the profession of lawyers. And do they actually make things better for everyone else, or just themselves?

Submission + - The 32-Bit Dog Ate 16 Million Kids' CS Homework

theodp writes: Tech backed-Code.org explains in a blog post that it encountered technical difficulties Friday that temporarily made the work of 16 million K-12 students who have used the nonprofit's Code Studio offering disappear. Code.org CTO Jeremy Stone gave the kids an impromptu lesson on the powers of two with his explanation of why The Cloud ate their homework: "This morning, at 9:19 am PST, coding progress by students stopped saving on Code Studio, and the issue briefly brought the Code Studio site down. We brought the site back up shortly thereafter but student progress was still not being saved, and instead students saw an outdated message about the Hour of Code from December. [...] The way we store student coding activity is in a table that until today had a 32-bit index. What this means is that the database table could only store 4 billion rows of coding activity information. We didn’t realize we were running up to the limit, and the table got full. We have now made a new student activity table that is storing progress by students. With the new table, we are switching to a 64-bit index which will hold up to 18 quintillion rows of information. On the plus side, this new table will be able to store student coding information for millions of years. On the down side, until we’ve moved everything over to the new table, some students’ code from before today may temporarily not appear, so please be patient with us as we fix it."

Submission + - Trump's problem: Will China, Japan, Europe or U.S. build first exascale system? (computerworld.com)

dcblogs writes: The global race to develop an exascale supercomputer may be a Sputnik moment for President Donald Trump. The new administration has said nothing about its plans for supercomputing. Will it participate in the global race to develop an exascale supercomputer? The supercomputing race is going to turn very real for the Trump administration. China and Japan both have plans to deliver an exascale system by 2020. Europe is well in the race and has targeted 2022, but it could deliver something earlier. The U.S. plan had a delivery date of 2023-24 — until a few weeks ago. In the final weeks of the Obama administration, a new plan emerged to produced the nation's first exascale system by 2021. The U.S. Department of Energy's Exascale Computing Project "is now a 7-year project, not a 10-year project, but it will cost more," said Paul Messina, a computer scientist at the Argonne National Laboratory and head of the project. But the Hill recently reported that the Trump administration is considering cutting the Dept. of Energy's advance computing budget to 2008 levels.

Elite Scientists Have Told the Pentagon That AI Won't Threaten Humanity (vice.com) 144

An anonymous reader quotes a report from Motherboard: A new report authored by a group of independent U.S. scientists advising the U.S. Dept. of Defense (DoD) on artificial intelligence (AI) claims that perceived existential threats to humanity posed by the technology, such as drones seen by the public as killer robots, are at best "uninformed." Still, the scientists acknowledge that AI will be integral to most future DoD systems and platforms, but AI that could act like a human "is at most a small part of AI's relevance to the DoD mission." Instead, a key application area of AI for the DoD is in augmenting human performance. Perspectives on Research in Artificial Intelligence and Artificial General Intelligence Relevant to DoD, first reported by Steven Aftergood at the Federation of American Scientists, has been researched and written by scientists belonging to JASON, the historically secretive organization that counsels the U.S. government on scientific matters. Outlining the potential use cases of AI for the DoD, the JASON scientists make sure to point out that the growing public suspicion of AI is "not always based on fact," especially when it comes to military technologies. Highlighting SpaceX boss Elon Musk's opinion that AI "is our biggest existential threat" as an example of this, the report argues that these purported threats "do not align with the most rapidly advancing current research directions of AI as a field, but rather spring from dire predictions about one small area of research within AI, Artificial General Intelligence (AGI)." AGI, as the report describes, is the pursuit of developing machines that are capable of long-term decision making and intent, i.e. thinking and acting like a real human. "On account of this specific goal, AGI has high visibility, disproportionate to its size or present level of success," the researchers say.

Comment As usual the non-technical get screwed (Score 0) 20

That's nice that they offer the flexibility, but why on earth is the default the one worse for battery life? A non technical user will generally not appreciate the extra resolution while they WOULD appreciate the extra battery life... All users will know is they get an update and the battery life is worse.

This move seems like one that is done by marketing (to make the phones generally look better) than from any group that considers user happiness.
