China's fleet of electric buses appear to be denting oil demand more than electric cars. "By the end of this year, a cumulative 270,000 barrels a day of diesel demand will have been displaced by electric buses, most of it in China," reports Bloomberg, citing a new report published by BloombergNEF. "That's more than three times the displacement by all the world's passenger electric vehicles (a market where Tesla has a share of about 12 percent)." From the report: Despite rapid growth, the impact on the oil market from electric vehicles remains relatively small. Collectively, buses and electric vehicles account for about 3 percent of oil demand growth since 2011, and 0.3 percent of current global consumption, according to BloombergNEF figures and data from the International Energy Agency. Buses matter more because of their size and constant use. For every 1,000 electric buses on the road, 500 barrels of diesel are displaced each day, BloombergNEF estimates. By comparison, 1,000 battery electric vehicles remove just 15 barrels of oil demand.

Still, the EV market's impact on oil consumption is only going to grow. By 2040, electric vehicles could displace much as 6.4 million barrels a day of demand, while fuel efficiency improvements will erase another 7.5 million barrels a day, according to BloombergNEF's May 2018 long-term EV outlook.

schwit1 shares a report from ScienceAlert: Researchers at the University of Southern Carolina (USC) claim to have created the first AI-controlled robotic limb that can learn how to walk without being explicitly programmed to do so. The algorithm they used is inspired by real-life biology. Just like animals that can walk soon after birth, this robot can figure out how to use its animal-like tendons after only five minutes of unstructured play.

Today, most robots take months or years before they are ready to interact with the rest of the world. But with this new algorithm, the team has figured out how to make robots that can learn by simply doing. This is known in robotics as "motor babbling" because it closely mimics how babies learn to speak through trial and error. "During the babbling phase, the system will send random commands to motors and sense the joint angles," co-author Ali Marjaninejad an engineer at USC, told PC Mag. "Then, it will train the three-layer neural network to guess what commands will produce a given movement. We then start performing the task and reinforce good behavior."

pgmrdlm writes: Defense officials want to test a neutral particle-beam in orbit in fiscal 2023 as part of a ramped-up effort to explore various types of space-based weaponry. They've asked for $304 million in the 2020 budget to develop such beams, more powerful lasers, and other new tech for next-generation missile defense. Such weapons are needed, they say, to counter new missiles from China, Russia, North Korea and Iran. But just figuring out what might work is a difficult technical challenge.

So the Pentagon is undertaking two studies. The first is a $15 million exploration of whether satellites outfitted with lasers might be able to disable enemy missiles coming off the launch pad. Defense officials have said previously that these lasers would need to be in the megawatt class. They expect to finish the study within six months. They're also pouring money into a study of space-based neutral particle beams, a different form of directed energy that disrupts missiles with streams of subatomic particles traveling close to light speed -- as opposed to lasers, whose photons travel at light speed.

Google researcher James Forshaw discovered a new class of vulnerability in Windows before any bug had actually been exploited. The involved parts of the flaw "showed that there were all the basic elements to create a significant elevation of privilege attack, enabling any user program to open any file on the system, regardless of whether the user should have permission to do so," reports Ars Technica. Thankfully, Microsoft said that the flaw was never actually exposed in any public versions of Windows, but said that it will ensure future releases of Windows will not feature this class of elevation of privilege. Peter Bright explains in detail how the flaw works. Here's an excerpt from his report: The basic rule is simple enough: when a request to open a file is being made from user mode, the system should check that the user running the application that's trying to open the file has permission to access the file. The system does this by examining the file's access control list (ACL) and comparing it to the user's user ID and group memberships. However, if the request is being made from kernel mode, the permissions checks should be skipped. That's because the kernel in general needs free and unfettered access to every file. As well as this security check, there's a second distinction made: calls from user mode require strict parameter validation to ensure that any memory addresses being passed in to the function represent user memory rather than kernel memory. Calls from kernel mode don't need that same strict validation, since they're allowed to use kernel memory addresses.

Accordingly, the kernel API used for opening files in NT's I/O Manager component looks to see if the caller is calling from user mode or kernel mode. Then the API passes this information on to the next layer of the system: the Object Manager, which examines the file name and figures out whether it corresponds to a local filesystem, a network filesystem, or somewhere else. The Object manager then calls back in to the I/O Manager, directing the file-open request to the specific driver that can handle it. Throughout this, the indication of the original source of the request -- kernel or user mode -- is preserved and passed around. If the call comes from user mode, each component should perform strict validation of parameters and a full access check; if it comes from kernel mode, these should be skipped. Unfortunately, this basic rule isn't enough to handle every situation. For various reasons, Windows allows exceptions to the basic user-mode/kernel-mode split. Both kinds of exceptions are allowed: kernel code can force drivers to perform a permissions check even if the attempt to open the file originated from kernel mode, and contrarily, kernel code can tell drivers to skip the parameter check even if the attempt to open the file appeared to originate from user mode. This behavior is controlled through additional parameters passed among the various kernel functions and into filesystem drivers: there's the basic user-or-kernel mode parameter, along with a flag to force the permissions check and another flag to skip the parameter validation...

The Huffington Post ran a bombshell report this week on one of a handful of people who have "figured out how to manipulate Wikipedia's supposedly neutral system to turn a profit." They're describing Ed Sussman, a former head of digital for Fast Company and Inc.com who's now paid to do damage control by relentlessly lobbying for changes to Wikipedia pages. "In just the past few years, companies including Axios, NBC, Nextdoor and Facebook's PR firm have all paid him to manipulate public perception using a tool most people would never think to check. And it almost always works." Spin reports: The benefit of hiring Sussman, aside from insulating talking heads from the humiliation of being found to have edited their own pages, is that he applies the exacting and annoying vigor of an attorney to Wikipedia's stringent editing rules. Further, because his opponents in these arguments are not opposing lawyers but instead Wikipedia's unpaid editors, he's really effective. From HuffPost:

"Sussman's main strategy for convincing editors to make the changes his clients want is to cite as many tangentially related rules as possible (he is, after all, a lawyer). When that doesn't work, though, his refusal to ever back down usually will. He often replies to nearly every single bit of pushback with walls of text arguing his case. Trying to get through even a fraction of it is exhausting, and because Wikipedia editors are unpaid, there's little motivation to continue dealing with Sussman's arguments. So he usually gets his way."

NBC and Axios confirmed that they hired Sussman, and an Axios spokesperson told HuffPost that the site "hired him to correct factual inaccuracies." The spokesperson added "pretty sure lots of people do this," which may or may not be true.
Sussman's web site argues he's addressing "inaccurate or misleading information...potentially creating severe business problems for its subject," bragging in his FAQ that when he's finished, "the article looks exactly the same" to an outsider -- and that his success rate is 100%.

An anonymous reader quotes Fast Company: Although widely held, the belief that merit rather than luck determines success or failure in the world is demonstrably false. This is not least because merit itself is, in large part, the result of luck. Talent and the capacity for determined effort, sometimes called "grit," depend a great deal on one's genetic endowments and upbringing.

This is to say nothing of the fortuitous circumstances that figure into every success story. In his book Success and Luck, the U.S. economist Robert Frank recounts the long-shots and coincidences that led to Bill Gates's stellar rise as Microsoft's founder, as well as to Frank's own success as an academic. Luck intervenes by granting people merit, and again by furnishing circumstances in which merit can translate into success. This is not to deny the industry and talent of successful people. However, it does demonstrate that the link between merit and outcome is tenuous and indirect at best. According to Frank, this is especially true where the success in question is great, and where the context in which it is achieved is competitive. There are certainly programmers nearly as skilful as Gates who nonetheless failed to become the richest person on Earth. In competitive contexts, many have merit, but few succeed. What separates the two is luck.

In addition to being false, a growing body of research in psychology and neuroscience suggests that believing in meritocracy makes people more selfish, less self-critical, and even more prone to acting in discriminatory ways.
The article cites a pair of researchers who "found that, ironically, attempts to implement meritocracy leads to just the kinds of inequalities that it aims to eliminate.

"They suggest that this 'paradox of meritocracy' occurs because explicitly adopting meritocracy as a value convinces subjects of their own moral bona fides."

An anonymous reader shares a report: Pilots now spend more time learning automated systems than practicing hands-on flying, so newer pilots are less comfortable with taking manual control when the computer steers them wrong, according to interviews with a dozen pilots and pilot instructors at major airlines and aviation universities around the world. "The automation in the aircraft, whether it's a Boeing or an Airbus, has lulled us into a sense of security and safety," said Kevin Hiatt, a former Delta Air Lines pilot who later ran flight safety for JetBlue. Pilots now rely on autopilot so often, "they become a systems operator rather than a stick-and-rudder pilot."

As a result, he said, "they may not exactly know or recognize quickly enough what is happening to the aircraft, and by the time they figure it out, it may be too late." [...] While automation has contributed to the airline industry's stellar safety record in recent years, it has also been a factor in many of the crashes that have still occurred around the world. A 2011 study by a federal task force found that in about 60 percent of 46 recent accidents, pilots had trouble manually flying the plane or handling the automated controls. Complicated automation systems can also confuse pilots and potentially cause them to take action they shouldn't, pilots said.

Tumblr's ban on pornography and adult content has led to an estimated fifth of its users deserting the platform. From a report: Tumblr's ban on pornography and adult content has led to a fifth of its users deserting the platform, figures reveal. The ban, which came into effect on 17 December, provoked a backlash from users who claimed it would penalise sex-positive, LGBT and NSFW art communities. Visits to the Tumblr website fell from 521 million in December to 437 million in January and 370 million in February, according to data from web analytics firm SimilarWeb. Tumblr's decision to update its content policy came after the discovery of child sexual abuse imagery on its blogs.

Google's latest speech recognition works entirely offline, eliminating the delay that many other voice assistants have to return your query. "The delay occurs because your voice, or some data derived from it anyway, has to travel from your phone to the servers of whoever operates the service, where it is analyzed and sent back a short time later," reports TechCrunch. "This can take anywhere from a handful of milliseconds to multiple entire seconds (what a nightmare!), or longer if your packets get lost in the ether." The only major downside with Google's new system is its limited availability. As of right now, it's only available to people with a Pixel smartphone. From the report: Why not just do the voice recognition on the device? There's nothing these companies would like more, but turning voice into text on the order of milliseconds takes quite a bit of computing power. It's not just about hearing a sound and writing a word -- understanding what someone is saying word by word involves a whole lot of context about language and intention. Your phone could do it, for sure, but it wouldn't be much faster than sending it off to the cloud, and it would eat up your battery. But steady advancements in the field have made it plausible to do so, and Google's latest product makes it available to anyone with a Pixel.

Google's work on the topic, documented in a paper here, built on previous advances to create a model small and efficient enough to fit on a phone (it's 80 megabytes, if you're curious), but capable of hearing and transcribing speech as you say it. No need to wait until you've finished a sentence to think whether you meant "their" or "there" -- it figures it out on the fly. So what's the catch? Well, it only works in Gboard, Google's keyboard app, and it only works on Pixels, and it only works in American English. So in a way this is just kind of a stress test for the real thing. "Given the trends in the industry, with the convergence of specialized hardware and algorithmic improvements, we are hopeful that the techniques presented here can soon be adopted in more languages and across broader domains of application," writes Google in their blog post.

Americans are spreading their book consumption across several formats, and the use of audiobooks is rising, Pew Research said in a report published on Thursday. From the report: About three-quarters (74%) of Americans have read a book in the past 12 months in any format, a figure that has remained largely unchanged since 2012, according to a Pew Research Center survey conducted in January. Print books remain the most popular format for reading, with 67% of Americans having read a print book in the past year.

And while shares of print and e-book readers are similar to those from a survey conducted in 2016, there has been a modest but statistically significant increase in the share of Americans who read audiobooks, from 14% to 18%. Overall, Americans read an average (mean) of 12 books per year, while the typical (median) American has read four books in the past 12 months. Each of these figures is largely unchanged since 2011, when the Center first began conducting the surveys of Americans' book reading habits.

Despite some growth in certain digital formats, it remains the case that relatively few Americans consume digital books (which include audiobooks and e-books) to the exclusion of print. Some 39% of Americans say they read only print books, while 29% read in these digital formats and also read print books. Just 7% of Americans say they only read books in digital formats and have not read any print books in the past 12 months. Some demographic groups are more likely than others to be digital-only book readers, but in general this behavior is relatively rare across a wide range of demographics. For example, 10% of 18- to 29-year-olds only read books in digital formats, compared with 5% of those ages 50-64 and 4% of those 65 and older.

According to a new paper from the Georgia Institute of Technology, autonomous cars could disproportionately endanger pedestrians with darker skin, a troubling sign of how AI can inadvertently reproduce prejudices from the wider world. Futurism reports: [In the paper, the researchers] detail their investigation of eight AI models used in state-of-the-art object detection systems. These are the systems that allow autonomous vehicles to recognize road signs, pedestrians, and other objects. They tested these models using images of pedestrians divided into two categories based on their score on the Fitzpatrick scale, which is commonly used to classify human skin color. According to the researchers' paper, the models exhibited "uniformly poorer performance" when confronted with pedestrians with the three darkest shades on the scale. On average, the models' accuracy decreased by 5 percent when examining the group containing images of pedestrians with darker skin tones, even when the researchers accounted for variables such as whether the photo was taken during the day or at night. Thankfully, the researchers were able to figure out what was needed to avoid a future of biased self-driving cars: start including more images of dark-skinned pedestrians in the data sets the systems train on and place more weight on accurately detecting those images.

Slashdot reader and Motherboard writer dmoberhaus was the final participant in the world's first brain imaging study on salvinorin A, the psychoactive chemical in salvia divinorum. He wrote about what it's like to participate in a psychedelic drug trial, and why he volunteered to smoke the world's least favorite hallucinogen for science. Here's an excerpt from his report: I was first introduced to salvia when I was a freshman in high school, and by the time I graduated I had smoked it about a dozen times. In retrospect, I would not describe a single one of those experiences as "pleasant," "enjoyable," or "fun." The last time I used salvia was almost a decade ago, and during that trip I became convinced that I had been irreversibly transformed into a suspension bridge. Good times. Despite a history of bad experiences with the substance, I volunteered for the Johns Hopkins salvinorin A study out of a suspicion that salvia probably had more to offer than what I experienced in high school. As a teen, each of my salvia experiences was under less than ideal conditions -- usually at a party or in a park after curfew. These sorts of situations lend themselves to paranoia and anxiety, which don't mix well with a strong dissociative hallucinogen. I figured if the settings were changed to a relaxed environment where I was surrounded by medical professionals, perhaps the nature of the trip would as well.
[...]
For the first salvia session I laid on the couch and donned an eye mask while [Manoj Doss, a postdoctoral researcher who specializes in memory] sat at the far end of the room with the smoking apparatus. The simple device consisted of a small glass bulb with a plastic hose connected to the top and was described to me as an "FDA-approved crack pipe." Along the bottom of the bulb was a barely noticeable residue of a white crystalline substance, which I was informed was one dose of 99.9% pure salvinorin A. I was given one end of the hose and instructed to begin a 45-second long inhale as Doss vaporized the salvinorin A with a butane torch. At the same time, Clifton began to play a new age soundtrack through speakers and came to put his hand on my leg to ground me during the trip. When the 45 seconds were up, I exhaled and felt the effects of the salvia almost immediately.

The first thing I noticed was the feeling of my body dissolving. Shortly after I began feeling the physical effects, the hallucinations began. I felt as though my head had split in two and a patterned stream began flowing from both sides of my face. This stream was a "harlequin pattern" of large brown and white diamonds that flowed away from me and began to form the "boundary" of an infinite three-dimensional space. These diamonds continued to tessellate to an infinite point and I felt as though I were suspended above this expanse, hanging like a figure head hangs off the bow of a ship. Throughout the trip, I remember being overcome by the profound beauty of the scene I was witnessing. If I tried to focus, I could remember that in base reality I was in a room in Johns Hopkins, but that didn't alleviate the feeling of being in an entirely separate reality, as though I were sitting in a container that cordoned me off from the 'normal' world. In summary, Oberhaus said "the experience was quite pleasant." He added: "I only had a brief moment of panic when it seemed like one of the notes in the new age soundtrack had been held for far too long. I began to worry that time was dilating and that I might be trapped in this space for eternity. When the music progressed to the next note, however, the panic quickly subsided and time resumed its normal cadence."

Oberhaus then took a higher dose the following day in an MRI machine. While the first dose of salvia in the machine didn't produce anything special, likely because it was a placebo, a very low dose, or that he had made some error during inhalation, the second dose in the machine resulted in a slightly less intense trip than the very first dose. "The reason, I think, was that the loud and persistent sounds of the MRI machine kept me tethered to the outside world and I was unable to fully immerse myself in the world that the salvia was generating," writes Oberhaus. "Still, I would describe it as a pleasant and visually striking experience."

A seemingly complex set of characters like "ji32k7au4a83" is a very common password among users, it turns out. From a report: This interesting bit of trivia comes from self-described hardware/software engineer Robert Ou, who recently asked his Twitter followers if they could explain why this seemingly random string of numbers has been seen by Have I Been Pwned (HIBP) over a hundred times.

Have I Been Pwned is an aggregator that was started by security expert Troy Hunt to help people find out if their email or personal data has shown up in any prominent data breaches. One service it offers is a password search that allows you to check if your password has shown up in any data breaches that are on the radar of the security community. In this case, "ji32k7au4a83" has been seen by HIBP in 141 breaches. Several of Ou's followers quickly figured out the solution to his riddle. The password is coming from the Zhuyin Fuhao system for transliterating Mandarin. The reason it's showing up fairly often in a data breach repository is because "ji32k7au4a83" translates to English as "my password."

An anonymous reader shares a report: The median rent for a one bedroom apartment in San Francisco has reached a new peak of $3,690, according to survey data from Zumper, a home and apartment rental app. That's also a rise of nearly 9 percent from the same time last year, the survey found. Not only are those figures high enough to make your bank account cringe, but they're also nearly 30 percent higher than New York City and more than double the prices in Miami. Seattle, home to Amazon and Microsoft, rang in at $1,970 and Washington, DC, hit $2,150.

Oh, and by the way, while San Francisco's prices rose, the median price of one bedroom apartments across the US dropped nearly half a percent during this same time. That means while San Francisco's prices climbed, the country's prices fell. "Though there may be a ton of cash flowing through the city and surrounding areas soon, many of these workers will not immediately invest in a home and may, instead, take their money to both travel and upgrade their rental situation," Zumper wrote in a blog post Thursday.

"Technology hasn't fallen short of its promise. Tech companies have," argues Evan Selinger, a philosophy professor at Rochester Institute of Technology, reporting on a new "collaborative video response to IBM's Dear Tech Ad" (which was aired during last week's telecast of the Oscar's). Earlier Selinger wrote: [IBM's] infantilizing ad depicts technology as if it were an autonomous person, a benevolent Santa Claus figure that can give great products to all the good little girls and boys if they ask politely.... It all sounds nice. But the message obscures the fact that technology hasn't fallen short of its promise. It's recalcitrant tech companies that need to change. That includes IBM....

IBM isn't alone in this sunny disingenuousness. Its competitors also give lip service to listening to our hopes and dreams while shutting down criticism that's voiced to make things better... A commercial like this one can't avoid being an empty marketing pitch when it represents a contested concept as a clear and unambiguous wish that technology can magically grant just as easily as Santa can satisfy a request for a new smartphone.
So a team of tech critics including Joy Buolamwini of the MIT Media Lab "created an alternative to IBM's ad. It's a provocative, line-by-line, video counterstatement" -- not "Dear Tech," but "Dear Tech Company."

Here are some of its more provocative quotes:

"We have a pretty complicated relationship."

"Your track record is mixed."

"Really mixed."

"And you have the potential to do immense harm."

"Are you only benefiting a few?"

"While many more suffer?"

The new counter-ad urges its viewers to demand more accountability from tech companies. (Sasha Costanza-Chock, an associate professor of civic media at MIT, even argues for companies "that treat people as more than data subjects for surveillance capitalism.") In a follow-up article, Selinger writes:

The most dangerous message promoted by the Dear Tech commercial is that socially responsible technology will be on its way simply because people are asking for it. This way of characterizing change suggests tech companies aren't incentivized to promote outcomes that are more self-serving than giving the public what it deserves.

The new video says, "Let's make time to understand the impact of technology on people's lives." It's a powerful message. Too bad this ad doesn't have an Oscars-sized budget behind it.

Amazon's physical Dash buttons are no more. The e-commerce giant has stopped selling its tap-to-order Dash buttons as of February 28th. From a report: If you still proudly use a Dash button (or a few dozen), don't worry: Amazon plans to continue supporting new orders through existing Dash buttons so long as the public keeps using them. So what killed the Dash button's future? Well, by Amazon's telling, the device was a victim of its own success, since it helped nudge forward the concept of the connected home to what it is today. Daniel Rausch, an Amazon vice president who helped grow the Dash program from its start, said that back in early 2015, when the Dash button first came out, there were far fewer options for connected home gadgets. Amazon workers were trying to figure out a way "to make shopping disappear" for grocery list items like paper towels and printer ink and whatever else is pretty not-fun to go out and buy, Rausch said.

The New York Times reported Thursday that an open letter will be published in the Times on Friday that asks Amazon to reconsider its decision to walk away from its plan to build a 25,000-employee campus in Long Island City, Queens. The company pulled the plug on the project, dubbed HQ2, following vocal and persistent opposition to the plan after it was announced three months ago. CNET reports: The letter was signed by the CEOs of Mastercard, Warby Parker, Goldman Sachs, Tishman Speyer and Jetblue, among others. The presidents of the Building & Construction Trades Council of Greater New York and state AFL-CIO, which were expecting thousands of construction jobs to come from the project, also signed, as did U.S. Reps. Hakeem Jeffries and Carolyn Maloney. "We know the public debate that followed the announcement of the Long Island City project was rough and not very welcoming," the letter stated. "Opinions are strong in New York -- sometimes strident. We consider it part of the New York charm! But when we commit to a project as important as this, we figure out how to get it done in a way that works for everyone."

New York Gov. Andrew Cuomo has also had several conversations with Amazon, including CEO Jeff Bezos, about bringing back the project, the Times said. The letter and Cuomo's behind-the-scenes efforts are part of the latest fallout since Amazon abandoned HQ2 in New York. The opposition has celebrated the exit as a victory for grassroots campaigns and a stand against lavish government incentives for new development plans. Amazon was slated to get about $3 billion in tax breaks for building the project. Supporters, who weren't as vocal during the run-up to Amazon leaving, expressed shock and consternation about Amazon's decision and worried that New York would appear unfriendly to new businesses. While the business community was broadly seen as in favor of the project, the letter shows how both the camps supporting and opposing HQ2 included unions and Democratic U.S. congress members.

An anonymous reader quotes a report from Ars Technica, written by Peter Bright: Ever since the first Xbox was released, an obvious question has been hanging in the air: Microsoft already owns one of the premier gaming platforms, the PC, and both the original Xbox and the current Xbox One are more or less PCs anyway, so when is Microsoft going to bring the two together and let us play Xbox games on Windows? With the new Windows 10 builds, it looks like the company is taking some big steps in that direction. Microsoft has put big chunks of the Xbox infrastructure into Windows 10. This starts right from the moment you download the game: it's coming from the Xbox distribution servers, not the usual ones for Store apps. The game package itself uses a format called .xvc, which is used for Xbox One games, and there are PowerShell commands to work with these .xvc files and install .xvc games. Microsoft Gaming Services includes portions of this Xbox infrastructure; it includes a couple of drivers ("Microsoft Gaming Filesystem Driver" and "Microsoft Gaming Install Filter Driver"), along with a number of libraries that provide Xbox APIs.

The last few Windows 10 preview builds have included some vague instructions from Microsoft to install a special edition of a game, State of Decay, and report any problems with the process. There are no problems with playing the game but, rather, problems with installing and launching it. The instructions didn't give any indication as to why or what to look for. Naturally, people have been taking a closer look to see what's special about State of Decay and figure out why Microsoft is having Windows Insiders test it. Nazmus Khandaker, Rafael Rivera, and the pseudonymous WalkingCat have been poking around both the special edition of State of Decay and a helper application called Microsoft Gaming Services that insider machines are running. Brad Sams wrote up his findings. [...] The State of Decay package does nonetheless contain PC-oriented elements. In particular, it tries to install and update the DirectX runtime during its setup. We the users don't seem to be at the stage of simply running Xbox games unmodified on our PCs, or at least, not yet. But it looks as if the groundwork is being laid. The strange preview of a 2020 Windows release looks like it contains even more of this infrastructure, with signs of a layer to support Xbox's Direct3D variant on PC. "Microsoft could go the whole hog and simply make a Windows 10 PC with a suitable hardware spec into an Xbox that can play any Xbox game," writes Bright, adding: "it might just be there as a simple option for developers to enable if they choose."

A federal judge has blocked Washington State's 2004 cyberstalking law after ruling that a key provision violated First Amendment protections for free speech due to vague terms. "Its prohibitions against speech meant to 'harass, intimidate, torment or embarrass' weren't clearly defined, according to the judge, and effectively criminalized a 'large range' of language guarded under the Constitution," reports Engadget. "You could theoretically face legal action just by criticizing a public figure." From the report: The ruling came after a retired Air Force Major, Richard Rynearson III, sued to have the law overturned. He claimed that Kitsap County threatened to prosecute him under the cyberstalking law for criticizing an activist involved with a memorial to Japanese victims of U.S. internment camps during World War II. While Rynearson would use "invective, ridicule, and harsh language," the judge said, his language was neither threatening nor obscene.

Officials had contended that the law held up because it targeted conduct, not the speech itself. They also maintained that Rynearson hadn't shown evidence of a serious threat -- just that the prosecutor's office would see how Rynearson behaved and take action if necessary. A county court had already tossed out the activist's restraining order against Rynearson over free speech. It's not clear whether Washington will appeal the decision. If the ruling stays, though, it could force legislators to significantly narrow the scope if it wants a cyberstalking law to remain in place. This might also set a precedent that could affect legislation elsewhere in the country. The Electronic Frontier Foundation praises the judge's decision, adding: "This is all valuable speech that is protected by the First Amendment, and no state law should be allowed to undermine these rights. We are pleased that the judge has agreed."

"Oumuamua, the first object ever seen passing through our solar system from interstellar space, was thought to be emitting gas like a comet to explain its weird motion," reports Syfy Wire, "but a new idea is that the comet is just very, very porous."

Astronomer Phil Plait writes: It was hard to tell what it was; it was too small, faint, and far away to get good observations, and worse, it was only seen on its way out, so it was farther from us literally every day. Then another very weird thing happened: More observations allowed a better determination of its trajectory, and it was found that it wasn't slowing down fast enough. As it moves away, the Sun's gravity pulls on it, slowing it down...but it wasn't slowing down enough. Some force was acting on it, accelerating it very slightly... A new paper has come out that might have a solution, and it's really clever. Maybe 'Oumuamua's not flat. Maybe it's fluffy... [And thus moved by the force of sunlight giving it a tiny push]

When stars are very young, they have a huge disk of material swirling around them; it's from this material that planets form. Out far from the star, where temperatures in the disk are cold, teeny tiny grains of dust and water ice can stick together in funny shapes, creating fractals... Materials made in a fractal pattern can be very porous, and in fact out in that protoplanetary disk around a young star, physical models show that objects can grow fractally until they're as big as 'Oumuamua, and have those extremely low densities needed to account for its weird behavior. So 'Oumuamua doesn't have to be a spaceship. It just has to be a snowflake! A three-dimensionally constructed phenomenally porous low-density snowflake... [T]he new paper suggests it came from a nearby star, and one that's relatively young (less than 100 million years). It formed out in the disk, and got ejected somehow, likely from a planet forming nearby giving it a boost from its gravity.
"I certainly hope we find more beasties like this one," Plait writes. "They can tell us so much about how planets form in other star systems, which is pretty hard to figure out from dozens or hundreds of light years away.

"It's a lot easier when they obligingly send bits of their building materials to us."
