A Chinese citizen journalist who covered Wuhan's coronavirus outbreak has been jailed for four years. From a report: Zhang Zhan was found guilty of "picking quarrels and provoking trouble", a frequent charge against activists. The 37-year-old former lawyer was detained in May, and has been on hunger strike for several months. Her lawyers say she is in poor health. Ms Zhang is one of several citizen journalists who have run into trouble for reporting on Wuhan. There is no free media in China and authorities are known to clamp down on activists or whistleblowers seen as undermining the government's response to the outbreak.

An anonymous reader shares a report: More recent Nvidia graphics cards have a proprietary feature called Deep Learning Super Sampling (DLSS), and while it's often been touted as a powerful new rendering tool, the results have sometimes been underwhelming. Some of this is down to the oddly mixed-message around how DLSS was rolled-out: it only works on more recent Nvidia cards that are still near the cutting edge of PC graphics hardware⦠but DLSS is designed to render images at lower resolutions but display them as if they were rendered natively at a higher resolution. If you had just gotten a new Nvidia card and were excited to see what kind of framerates and detail levels it could sustain, what DLSS actually did sounded counterintuitive. Even games like Control, whose support of DLSS was especially praised, left me scratching my head about why I would want to use the feature. On my 4K TV, Control looked and ran identically well with and without DLSS, so why wouldn't I just max-out my native graphics settings instead rather than use a fancy upscaler? Intellectually, I understood the DLSS could produce similarly great looking images without taxing my hardware as much, but I neither fully believed it, nor had I seen a game where the performance gain was meaningful.

Cyberpunk 2077 converted me. DLSS is a miracle, and without it there's probably no way I would ever have been happy with my graphics settings or the game's performance. I have a pretty powerful video card, an RTX 2080 TI, but my CPU is an old i5 overclocked to about 3.9 GHz and it's a definite bottleneck on a lot of games. Without DLSS, Cyberpunk 2077 was very hard to get running smoothly. The busiest street scenes would look fine if I were in a static position, but a quick pan with my mouse would cause the whole world to stutter. If I was walking around Night City, I would get routine slow-downs. Likewise, sneaking around and picking off guards during encounters was all well and good but the minute the bullets started flying, with grenades exploding everywhere and positions changing rapidly, my framerate would crater to the point where the game verged on unplayable. To handle these peaks of activity, I had to lower my detail settings way below what I wanted, and what my hardware could support for about 80 percent of my time with the game. Without DLSS, I never found a balance I was totally happy with. The game neither looked particularly great, nor did it run very well. DLSS basically solved this problem for me. With it active, I could run Cyberpunk at max settings, with stable framerates in all but the busiest scenes.

According to a new study published in the journal Computers In Human Behavior, smartphone users initiate 89% of the interactions, with only 11% initiated by a notification. "This is at odds with previous academic literature and news reports which commonly claim that smartphone notifications are ruining your life, ruining productivity, and so on," reports PsychNewsDaily. From the report: "The perceived disruptiveness of smartphones is not mainly driven by external notifications," the study's authors write, "but by an urge of the user to interact with their phone that seems to occur in an almost automatic manner, just as a smoker would light a cigarette." [...] The researchers explain that many users felt compelled to check their phones even when they had switched off notifications. "Seeing this has made me realize that I don't even remember picking it up," one of the subjects said in a subsequent interview with the study's authors. The study also found that the average duration of a smartphone interaction was 64 seconds. About 50% of the interactions were 23 seconds or less.

The most common activity users engaged in when using their phones was checking WhatsApp, which accounted for 22% of interactions. [...] The second most common interaction, at 17% of the total, was a "lock screen check," which means briefly unlocking the phone to check for new notifications. In third place was interacting with Instagram (16%). Facebook and Facebook messenger together accounted for 13% of the interactions, e-mail for 6%, web browsing 4%, music 3%, Snapchat 2%, and photos 2%. Phone calls -- these devices are phones, after all -- only comprised about 1% of the interactions.

The participants generally considered e-mail notifications the most important. Likewise, they largely considered group chats a "source of distress," and found most group-chat messages unimportant. Smartphone interactions were longer when users were alone versus with others, and were also longer at home versus at work. Likewise, these interactions were shorter when participants received notifications, compared to when they "self-disrupt." This indicates that smartphone use is more purposeful when users receive notifications, and more "distraction-seeking" when they check their phones themselves. The researchers also found that the scrolling features on apps like Instagram and Facebook led to the longest interactions.

In a new essay at EFF.org, Cory Doctorow re-visits HP's anti-consumer "security updates" that disabled third-party ink cartridges (while missing real vulnerabilities that could actually bypass network firewalls).

Doctorow writes that it was just the beginning: HP's latest gambit challenges the basis of private property itself: a bold scheme! With the HP Instant Ink program, printer owners no longer own their ink cartridges or the ink in them. Instead, HP's customers have to pay a recurring monthly fee based on the number of pages they anticipate printing from month to month; HP mails subscribers cartridges with enough ink to cover their anticipated needs. If you exceed your estimated page-count, HP bills you for every page (if you choose not to pay, your printer refuses to print, even if there's ink in the cartridges). If you don't print all your pages, you can "roll over" a few of those pages to the next month, but you can't bank a year's worth of pages to, say, print out your novel or tax paperwork. Once you hit your maximum number of "banked" pages, HP annihilates any other pages you've paid for (but continues to bill you every month).

Now, you may be thinking, "All right, but at least HP's customers know what they're getting into when they take out one of these subscriptions," but you've underestimated HP's ingenuity. HP takes the position that its offers can be retracted at any time. For example, HP's "Free Ink for Life" subscription plan offered printer owners 15 pages per month as a means of tempting users to try out its ink subscription plan and of picking up some extra revenue in those months when these customers exceeded their 15-page limit. But Free Ink for Life customers got a nasty shock at the end of last month: HP had unilaterally canceled their "free ink for life" plan and replaced it with "a $0.99/month for all eternity or your printer stops working" plan...

For would-be robber-barons, "smart" gadgets are a moral hazard, an irresistible temptation to use those smarts to reconfigure the very nature of private property, such that only companies can truly own things, and the rest of us are mere licensors, whose use of the devices we purchase is bound by the ever-shifting terms and conditions set in distant boardrooms. From Apple to John Deere to GM to Tesla to Medtronic, the legal fiction that you don't own anything is used to force you to arrange your affairs to benefit corporate shareholders at your own expense. And when it comes to "razors and blades" business-model, embedded systems offer techno-dystopian possibilities that no shaving company ever dreamed of: the ability to use law and technology to prevent competitors from offering their own consumables. From coffee pods to juice packets, from kitty litter to light-bulbs, the printer-ink cartridge business-model has inspired many imitators.

HP has come a long way since the 1930s, reinventing itself several times, pioneering personal computers and servers. But the company's latest reinvention as a wallet-siphoning ink grifter is a sad turn indeed, and the only thing worse than HP's decline is the many imitators it has inspired.

"Development of Pyston, a variant of the Python runtime that uses just-in-time compilation to speed up the execution of Python programs, is back on again," reports InfoWorld — after a hiatus that began in 2017: Picking up where Dropbox left off, a new development team has released Pyston 2.0. Pyston provides what is ultimately intended to be a drop-in replacement for the standard Python runtime, CPython. It's compatible with Python 3.8, so programs that runs with that version of Python should run as-is on Pyston...

One of the goals of the project was to remain as close as possible to the original implementation of CPython, since many third-party projects make assumptions about CPython behavior. Thus Pyston 2.0 began with the existing CPython codebase and added features from Pyston 1.0 that worked well, such as caching attributes and JITting. Pyston's JIT no longer uses LLVM, but DynASM to emit assembly directly...

[U]nlike the original Pyston incarnation, the new version is closed-source for the time being, as its new stewards determine their business model.

TV cord-cutting is picking up steam, and AT&T's CEO predicts there's a long way to go before it stops. From a report: On an earnings call Thursday, AT&T Chief Executive Officer John Stankey said "we're probably going to see a little bit of a plateauing" when the number of homes subscribing to pay TV hits 55 million to 60 million. Most of those homes will include sports fans, he said. It's a stark outlook for an industry that's already suffered a long subscriber exodus. There were about 91 million pay-TV subscribers at the end of 2019, including some 8 million who signed up to online-TV bundles like Hulu and YouTube TV. About 3.5 million people cut the cord in the first half of the year, according to Bloomberg Intelligence. While AT&T, Comcast, Charter and other TV providers are focusing their businesses on delivering internet service, owners of cable channels are especially vulnerable. That's because more cord-cutting means lower subscriber fees, a key revenue stream. Stankey added that AT&T is focusing on growing its new online streaming service, HBO Max, to prepare for the future. AT&T said Thursday that it shed another 590,000 TV subscribers last quarter. With customer losses mounting, AT&T has been looking to sell the majority of its satellite-TV business, DirecTV.

It will become illegal for anyone in the UK to pick up and use their mobile phone while driving, under new legislation to be enacted next year. From a report: The change will end a loophole that can allow drivers to escape punishment for using a hand-held phone to take a photo or play a game. Mobiles will still be able to be used to pay for a drive-through takeaway. And drivers will still be able to use devices hands-free under the plans, the Department for Transport said. At present, making phone calls and sending text messages are banned while driving. Ministers have rejected calls to also ban the use of hands-free function, for example using a sat-nav in a phone cradle. Roads minister Baroness Vere said hand-held phone use behind the wheel was "distracting and dangerous" and that "for too long risky drivers have been able to escape punishment." The change in law would apply across the UK and is expected to come into effect early next year, depending on the outcome of the consultation.

"Josiah Zayner's plan was simple: replicate a Covid-19 vaccine that had worked in monkeys, test it on himself and then livestream the experiment online over a period of months," reports Bloomberg.

"Zayner discovered, testing a vaccine is far more complicated than he had imagined." Even though his experiment yielded a promising result, Zayner found too many unanswered questions to say that it worked. For one, it wasn't clear whether antibodies he found in his own body in extremely tiny measures before the experiment began made a difference... As the U.S. rushes to bring a vaccine to market far faster than has ever been done, Zayner said he has discovered why the long, slow process of clinical trials shouldn't be rushed. A promising early stage result is just that: promising...

Initially, Zayner assumed that the experiment he named Project McAfee, after the antiviral software, would be relatively straightforward. The vaccine selected had triggered protective immunity against the virus in rhesus macaque monkeys in a paper published in May. Zayner was able to order the same spike protein sequence from the DNA-synthesis company the researchers had used. The plan: He and two fellow biohackers — Daria Dantseva in Ukraine and David Ishee in Mississippi — would themselves test the concoction they ordered online. They would then livestream the entire process online over several months, with the first showing to occur in June.

But early on in the experiment, complications arose. Before starting, Zayner took a test at Lab Corp Inc. that told him he didn't already have antibodies to the virus. But when he performed a similar test on himself shortly afterward, he found that he did have some antibodies, just not enough to produce a positive result on Lab Corp's test. While those antibodies didn't appear to be the neutralizing type, he wondered whether the result came because the vaccine was picking up signals from antibodies to a different virus — or how this faint antibody signal might affect things. "I'm very suspicious of my own data," he said.

He's not alone. Hank Greely, a bioethicist at Stanford University, said Zayner's experiment pointed out an underappreciated reality of vaccine development. "Actually making the vaccine isn't that hard," he said. "It's testing it and knowing that it's safe — and knowing that it's effective...." Zayner's next project will focus on showing people how to grow chicken cells to make their own fake meat. With vaccines, Zayner concluded, "Large scale clinical trials are probably required, because it is so messy."

The source for this story is a post on Reddit, which Jalopnik argues "was corroborated with this remarkable video of Tesla's new Instant, Unplanned Convertible feature." I know we've covered Tesla's chronic quality control issues here before, and I realize that among hardcore Tesla-stans this may feel like we're picking on Tesla unfairly but in our defense, Tesla really does have some terrible quality issues. Sometimes we get a really dramatic and baffling issue, like this one where the fucking roof flew off a brand-new Model Y while the car was being driven home.
"The Tesla service center in Dublin did not return a message seeking comment," reports the Verge, adding "A spokesperson for Tesla also did not respond." Leaving them with nothing but the Redditor's own story: Nathaniel Galicia Chien was driving down Interstate 580 with his parents in their brand-new Tesla Model Y when he started to hear a lot of wind. "I thought a window was open," Chien recalled in an email to The Verge, "but half a minute later the entire glass top of the roof just flew off in the wind."

Chien said the incident occurred hours after he and his parents picked up the new Model Y from the Tesla dealership in Dublin, California. Right off the bat, they noticed some minor "fit and finish" problems, such as "spacing issues and unevenness in the gaps that are pretty well-known issues with new Teslas." But they didn't expect any problems with the crossover's mammoth panoramic glass roof, and certainly not on the same day they drove it off the dealer's lot.

For years, Tesla has been plagued by quality issues, but it seems to have grown worse with the release of the Model Y in 2019. Just this past summer, Tesla scored last in a survey of customers by researcher JD Power. Owners have flocked to online forums to complain about paint and trim problems, indentations in the seats, and loose seatbelts. But an entire roof flying off on the highway is a new kind of problem for Tesla... Chien said Tesla's service representatives said that "either the seal on the roof was faulty, or they somehow just forgot to seal the roof on entirely."
"They gave us a free rental to use in the meantime and offered to get it serviced," the Redditor posted this week, "but we just opted to wait for a brand new one."

BBC News reports: In 1991, the trade body that represents electrical companies in the U.S., the Edison Electric Institute, created a campaign called the Information Council for the Environment which aimed to "Reposition global warming as theory (not fact)". Some details of the campaign were leaked to the New York Times. "They ran advertising campaigns designed to undermine public support, cherry picking the data to say, 'Well if the world is warming up, why is Kentucky getting colder?' They asked rhetorical questions designed to create confusion, to create doubt," argued Naomi Oreskes, professor of the history of science at Harvard University and co-author of Merchants of Doubt. But back in the 1990 there were many campaigns like this...

Most of the organisations opposing or denying climate change science were right-wing think tanks, who tended to be passionately anti-regulation. These groups made convenient allies for the oil industry, as they would argue against action on climate change on ideological grounds. Jerry Taylor spent 23 years with the Cato Institute — one of those right wing think tanks — latterly as vice president. Before he left in 2014, he would regularly appear on TV and radio, insisting that the science of climate change was uncertain and there was no need to act.

Now, he realises his arguments were based on a misinterpretation of the science, and he regrets the impact he's had on the debate.
Harvard historian Naomi Oreskes discovered leading climate-change skeptics had also been prominent skeptics on the dangers of cigarette smoking. "That was a Eureka moment," Oreskes tells BBC News. "We realised this was not a scientific debate." Decades before the energy industry tried to undermine the case for climate change, tobacco companies had used the same techniques to challenge the emerging links between smoking and lung cancer in the 1950s... As a later document by tobacco company Brown and Williamson summarised the approach: "Doubt is our product, since it is the best means of competing with the 'body of fact' that exists in the minds of the general public." Naomi Oreskes says this understanding of the power of doubt is vital. "They realise they can't win this battle by making a false claim that sooner or later would be exposed. But if they can create doubt, that would be sufficient — because if people are confused about the issue, there's a good chance they'll just keep smoking...."

Academics like David Michaels, author of The Triumph of Doubt, fear the use of uncertainty in the past to confuse the public and undermine science has contributed to a dangerous erosion of trust in facts and experts across the globe today, far beyond climate science or the dangers of tobacco. He cites public attitudes to modern issues like the safety of 5G, vaccinations — and coronavirus.

"By cynically manipulating and distorting scientific evidence, the manufacturers of doubt have seeded in much of the public a cynicism about science, making it far more difficult to convince people that science provides useful — in some cases, vitally important — information.

"There is no question that this distrust of science and scientists is making it more difficult to stem the coronavirus pandemic."

In an interview with Bloomberg, Bill Gates was asked whether his contemporary Elon Musk could be considered the "next Steve Jobs," due to the advancements his companies Tesla and SpaceX have made in electric cars and reusable rockets, respectively. CNBC reports: "If you know people personally, that kind of gross oversimplification seems strange," Gates told Bloomberg in the interview published Thursday. There are some key differences between the way Musk and Jobs operate, Gates said. "Elon's more of a hands-on engineer. Steve was a genius at design and picking people and marketing," Gates said. "You wouldn't walk into a room and confuse them with each other." [...] As for Jobs, he "was such a wizard at over-motivating people ... I could see him casting the spells, and then I would look at people and see them mesmerized," Gates told podcast host Dax Shepard Aug. 20. Musk and Gates also have their differences. CNBC adds: In August, Gates wrote a blog post about electric vehicles, saying that they will "never be a practical solution" for replacing trucks and long-haul vehicles. Musk responded to Gates' comments on Twitter Sept. 11, saying that "he has no clue" about electric trucks. (Gates said in the Bloomberg interview that Musk's electric car "is a huge contribution to the climate change effort," that Tesla "did it with quality" and that "other car companies, seeing his success, will come [into the market].") [...] Of course, Gates own reputation has evolved. In the early Microsoft days, Gates was known for setting high standards for the company and being very tough on his team. "I certainly wasn't a sweetheart when I ran Microsoft," he said on Shepard's podcast.

NPR and PBS Frontline spent months digging into internal industry documents and interviewing top former officials. We found that the industry sold the public on an idea it knew wouldn't work -- that the majority of plastic could be, and would be, recycled -- all while making billions of dollars selling the world new plastic. NPR: The industry's awareness that recycling wouldn't keep plastic out of landfills and the environment dates to the program's earliest days, we found. "There is serious doubt that [recycling plastic] can ever be made viable on an economic basis," one industry insider wrote in a 1974 speech. Yet the industry spent millions telling people to recycle, because, as one former top industry insider told NPR, selling recycling sold plastic, even if it wasn't true. "If the public thinks that recycling is working, then they are not going to be as concerned about the environment," Larry Thomas, former president of the Society of the Plastics Industry, known today as the Plastics Industry Association and one of the industry's most powerful trade groups in Washington, D.C., told NPR.

In response, industry representative Steve Russell, until recently the vice president of plastics for the trade group the American Chemistry Council, said the industry has never intentionally misled the public about recycling and is committed to ensuring all plastic is recycled. [...] Here's the basic problem: All used plastic can be turned into new things, but picking it up, sorting it out and melting it down is expensive. Plastic also degrades each time it is reused, meaning it can't be reused more than once or twice. On the other hand, new plastic is cheap. It's made from oil and gas, and it's almost always less expensive and of better quality to just start fresh. All of these problems have existed for decades, no matter what new recycling technology or expensive machinery has been developed. In all that time, less than 10 percent of plastic has ever been recycled. But the public has known little about these difficulties.

Walmart said on Wednesday it would run a pilot project for delivery of grocery and household products through automated drones, along with end-to-end delivery firm Flytrex, as the U.S. retailer looks to beef up its delivery business. CNBC reports: Bentonville, Arkansas-based Walmart said the test would start on Wednesday in Fayetteville, North Carolina, with cloud-controlled drones picking up and dropping off select items. "We know that it will be some time before we see millions of packages delivered via drone. That still feels like a bit of science fiction," Tom Ward, senior vice-president, customer products, said in a statement.

Every year or so, Crunchbase News likes to take a look at what's hot in startup naming. The process involves reading names of over 1,000 recently founded and funded startups in English-speaking countries, looking for trends. It then get a naming expert's take on the situation. From the report: Probably the standout trend for the past year is the feel-good word. This could be a noun, adjective, adverb, or verb. The qualification is that it evokes something positive, commonly an admirable trait or desirable state of being. Examples include Mighty (workflow for remote teams), Cured (health care software), and Elate (operations platform). Part of the reason simple, positive words are cropping up more is that startups are less concerned about getting a dot-com domain with their exact brand name, said Athol Foden, president of Brighter Naming, a naming consultancy. They'll take an alternative suffix (Cured is Cured.health, for example) or add a word to the domain name (Elate, for instance, is goelate.com).

[...] Another popular branding approach is the straightforward description. Companies are picking names that describe exactly what they do. Some examples are: Grow Credit, a service for building credit histories, New Age Meats, a startup cultivating meat from animal cells, and The Browser Company. In Foden's view, there's something to be said for these simpler, clearer names. They tend to be easier to remember than a made-up brand name, and everyone knows how to spell them. [...] One of the most enduring startup naming strategies is the creative misspelling. By dropping vowels, adding consonants, or taking other steps, companies can get a name that's both familiar-sounding and unique. Over the past year, we've seen plenty of companies with misspelled word names raise seed funding. The lineup includes Cann, a maker of cannabis-infused tonics, Puzzl, a payroll provider for hourly workers, and Shef, an income-earning platform for local cooks.

Researchers have demonstrated that they can make a working 3D-printed copy of a key just by listening to how the key sounds when inserted into a lock. Slashdot reader colinwb writes: While you cannot hear the shape of a drum it seems you can hear the shape of one type of key from the sound it makes in the lock. That says it all really, but [here's how Soundarya Ramesh and her team at the National University of Singapore accomplished this feat]: "[The NUS team developed and tested what it calls SpiKey, an end-to-end attack technique for, as its name suggests, spying on Yale/Schlage type keys and using signal processing software to infer their correct shapes.] Once they have a key-insertion audio file, SpiKey's inference software gets to work filtering the signal to reveal the strong, metallic clicks as key ridges hit the lock's pins [and you can hear those filtered clicks online here]. These clicks are vital to the inference analysis: the time between them allows the SpiKey software to compute the key's inter-ridge distances and what locksmiths call the 'bitting depth' of those ridges: basically, how deeply they cut into the key shaft, or where they plateau out. If a key is inserted at a nonconstant speed, the analysis can be ruined, but the software can compensate for small speed variations.

The result of all this is that SpiKey software outputs the three most likely key designs that will fit the lock used in the audio file, reducing the potential search space from 330,000 keys to just three. 'Given that the profile of the key is publicly available for commonly used [pin-tumbler lock] keys, we can 3D-print the keys for the inferred bitting codes, one of which will unlock the door,' says Ramesh." The article has a link to a 15-minute video presentation of the research and to another article on the research.

Long-time Slashdot reader destinyland writes: What's up with Perl 7? Perl Foundation board member Ricardo Signes tried to sum up the state of the community in a detailed post to the "Perl 5 porters" mailing list. And in a section titled "To Break or Not To Break," he writes that "The central Perl 7 question is not about version numbering, but rather about backward compatibility guarantees..." And more specifically, it's how to respond to the question of whether Perl 5 "is too constrained by backward compatibility to grow significantly in utility or rate of use." He presents three possible responses:

— Reject the premise. "There is a lot of room for forward motion without breaking changes, if we would just stop trying to change the rules and move forward."

— Accept the premise, but then "let Perl continue along its current course, becoming ever more stable as it is used by an ever-diminishing audience until it is given its rightful place in the Hall of the Honored Dead."

— Or, "figure out which constraints can, like chains, be shrugged off so we can move ahead..."

While he sees merit in all three positions, the core hope of the Perl 7 plan is choice #3. "Maybe there are kinds of backward compatibility that can be shrugged off without disrupting the vast majority of Perl users, while making the language easier to use and (very importantly) easy to *continue* to improve." And more to the point, "We aren't picking up new core developers for a bunch of reasons, but one is 'it's just too much of a slog to -do- anything.' So I am in favor of making selective breakages in order to make the language better and the implementation more workable. I think this is the core of the Perl 7 plan, and the big question is 'what are those selective breakages.'"

That section is followed by another one titled "How Shall I Break Thee?" ("The impact on existing code is a big question to be answered. Nobody is arguing that we'll attract a new set of users and developers by first alienating all the existing ones.") While there's good suggestions, right now "The plan is to come up with a plan."

And this starts with creating a document to formalize the governance model of the Perl Steering Committee as their way of pre-forming some early consensus and refining ideas before they're then put up for general discussion on the mailing list, with a project manager giving final approval to the larger community's decisions. This will then be followed by "producing a clear set of intended changes..."

"Until that happens, I just hope for a little period of calm and good faith."

An anonymous reader quotes a report from Reuters: Alphabet's Google is picking up a 6.6% stake in ADT for $450 million, betting on the home security company's strong customer base and an army of technicians to drive sales of its Nest devices. The investment gives ADT the backing of a high-profile technology partner and broadens its services business. In return, Google gets access to about 6.5 million customers, strengthening its presence as it competes with Amazon's Ring and Boston-based SimpliSafe, among others. ADT said on Monday that the two companies would work on ways to package popular Google products like Home Mini, Nest Thermostat and Nest Wifi with ADT's strength in installation and maintenance.

"Later this year, we will begin integrating Google devices and make them available for installations to our customers," ADT Chief Executive Officer Jim DeVries told Reuters. "We will exclusively support Nest products," DeVries said, adding that the companies will build products together and start rolling them out next year. The companies will commit an additional $150 million each for co-marketing, product development, technology and employee training, ADT said.

An anonymous reader writes: Google is partnering with the Ubuntu Desktop team at Canonical to bring Linux support to its open source UI framework Flutter. Today's Linux alpha announcement also means Flutter developers can now deploy their apps to the Snap Store. Flutter group product manager Tim Sneath argues this is a big milestone because UI frameworks rarely become versatile and powerful enough for an operating system to depend on. He pointed to Windows being written in C++ rather than .NET, even for applets like the Calculator. Sneath also believes this shows Canonical is willing to invest in a first-class way to build apps for Linux, making Flutter on Linux an official part of Ubuntu. Additionally, enterprises can feel confident about picking Flutter -- it's more evidence of its longevity and technical excellence, Sneath said.

An anonymous reader quotes a report from Ars Technica: For the past year, WikiLeaks founder Julian Assange has sat in a London jail awaiting extradition to the US. This week, the US Justice Department piled on yet more hacking conspiracy allegations against him, all related to his decade-plus at the helm of an organization that exposed reams of government and corporate secrets to the public. But in Assange's absence, another group has picked up where WikiLeaks left off -- and is also picking new fights.

For roughly the past year and a half, a small group of activists known as Distributed Denial of Secrets, or DDoSecrets, has quietly but steadily released a stream of hacked and leaked documents, from Russian oligarchs' emails to the stolen communications of Chilean military leaders to shell company databases. Late last week, the group unleashed its most high-profile leak yet: BlueLeaks, a 269-gigabyte collection of more than a million police files provided to DDoSecrets by a source aligned with the hacktivist group Anonymous, spanning emails, audio files, and interagency memos largely pulled from law enforcement "fusion centers," which serve as intelligence-sharing hubs. According to DDoSecrets, it represents the largest-ever release of hacked US police data. It may put DDoSecrets on the map as the heir to WikiLeaks' mission -- or at least the one it adhered to in its earlier, more idealistic years -- and the inheritor of its never-ending battles against critics and censors. "Our role is to archive and publish leaked and hacked data of potential public interest," writes the group's cofounder, Emma Best, a longtime transparency activist, in a text message interview with WIRED. "We want to inspire people to come forward, and release accurate information regardless of its source."

A suite of experiments that use the gene-editing tool CRISPR-Cas9 to modify human embryos have revealed how the process can make large, unwanted changes to the genome at or near the target site. Nature reports: The first preprint was posted online on June 5 by developmental biologist Kathy Niakan of the Francis Crick Institute in London and her colleagues. In that study, the researchers used CRISPR-Cas9 to create mutations in the POU5F1 gene, which is important for embryonic development. Of 18 genome-edited embryos, about 22% contained unwanted changes affecting large swathes of the DNA surrounding POU5F1. They included DNA rearrangements and large deletions of several thousand DNA letters -- much greater than typically intended by researchers using this approach. Another group, led by stem-cell biologist Dieter Egli of Columbia University in New York City, studied embryos created with sperm carrying a blindness-causing mutation in a gene called EYS2. The team used CRISPR-Cas9 to try to correct that mutation, but about half of the embryos tested lost large segments of the chromosome -- and sometimes the entire chromosome -- on which EYS is situated. And a third group, led by reproductive biologist Shoukhrat Mitalipov of Oregon Health & Science University in Portland, studied embryos made using sperm with a mutation that causes a heart condition. This team also found signs that editing affected large regions of the chromosome containing the mutated gene.

The three studies offered different explanations for how the DNA changes arose. Egli and Niakan's teams attributed the bulk of the changes observed in their embryos to large deletions and rearrangements. Mitalipov's group instead said that up to 40% of the changes it found were caused by a phenomenon called gene conversion, in which DNA-repair processes copy a sequence from one chromosome in a pair to heal the other. Mitalipov and his colleagues reported similar findings in 2017, but some researchers were skeptical that frequent gene conversions could occur in embryos. They noted that the maternal and paternal chromosomes are not next to each other at the time the gene conversion is postulated to occur, and that the assays the team used to identify gene conversions could have been picking up other chromosomal changes, including deletions. Egli and his colleagues directly tested for gene conversions in their latest preprint and failed to find them, and Burgio points out that the assays used in the Mitalipov preprint are similar to those the team used in 2017. One possibility is that DNA breaks are healed differently at various positions along the chromosome, says Jin-Soo Kim, a geneticist at Seoul National University and a co-author of the Mitalipov preprint.
