Coinbase Exec's Brother Pleads Guilty In Crypto Insider Trading Case (decrypt.co) 16

Nikhil Wahi, brother of former Coinbase product manager Ishan Wahi, pleaded guilty in a Monday hearing to one count of conspiracy to commit wire fraud in connection with an alleged insider trading scheme. Decrypt reports: "Less than two months after he was charged, Nikhil Wahi admitted in court today that he traded in crypto assets based on Coinbase's confidential business information to which he was not entitled," said Damien Williams of the U.S. Attorney's Office in New York in a statement. "For the first time ever, a defendant has admitted his guilt in an insider trading case involving the cryptocurrency markets," Williams continued. "Today's guilty plea should serve as a reminder to those who participate in the cryptocurrency markets that the Southern District of New York will continue to steadfastly police frauds of all stripes and will adapt as technology evolves."

Nikhil now awaits sentencing in December, which could mean up to 20 years in prison. He has also been ordered to give back the money earned as a result of the illicit Coinbase trading, Williams said. Back in July, the Justice Department charged Ishan, Nikhil, and their friend Sameer Ramani with wire fraud conspiracy and wire fraud as it relates to cryptocurrency insider trading. The Securities and Exchange Commission also filed charges against the trio. While he was working at Coinbase, Ishan allegedly shared his insider knowledge of upcoming Coinbase listing announcements with Nikhil and Sameer to then profit from the listings by purchasing the tokens before they went live on Coinbase. In August, Ishan pled not guilty to the DOJ's charges. Now that his brother has pleaded guilty, it's unclear how Ishan's case will proceed and whether he will continue to fight the insider trading case.

According to the DOJ's statement released Monday, Nikhil implicated his brother Ishan and admitted to receiving tips from him. Nikhil then reportedly used numerous different crypto wallets in others' names to anonymize his insider trading. Concerns of insider trading at cryptocurrency exchanges extend beyond just this case, which is considered the first of its kind and is likely to set a precedent. Three Australian finance academics have posited that up to 25% of Coinbase listings in the past four years may have involved some insider trading.

Thousands of Google's Cafeteria Workers Unionized (washingtonpost.com) 33

This week as America celebrated Labor Day, the Washington Post told the story of how 4,000 cafeteria workers at Google quietly unionized during the pandemic: Google is famous for its cafeterias, which serve its legions of programmers and product managers everything from vegan poke to gourmet tacos — free. But the cooks and servers behind those meals are generally contractors who work for other companies, and do not get the generous perks and benefits reserved for Google employees. So over the past few years, thousands of them have unionized, securing higher wages, retirement benefits and free platinum health care coverage.

Unite Here, a 300,000-member union of hotel and food service workers, has been steadily working to unionize Silicon Valley cafeteria workers since 2018, experiencing the most success at Google. Employed by the contract companies Compass and Guckenheimer, those unionized now make up about 90 percent of total food services workers at Google, according to the union. Workers have unionized at 23 Google offices nationwide, including in Seattle and San Jose.

Now, the union is tackling new territory: the South.... Google workers in Atlanta employed by a different cafeteria company — Sodexo — presented their manager with a list of demands and said they plan to unionize.... [Last week] Sodexo and the union reached an agreement: Should a majority of workers choose to unionize, Sodexo would not try to block it.

The article notes that more than 230 Starbucks locations have also voted to unionize since last year. But Google offers a case study in the difference it can make, according to the Post's summary of observations from D. Taylor, the president of Unite Here.

"The average unionized worker at a Google cafeteria makes $24 an hour, pays little to nothing for health insurance and has access to a pension plan. At Sodexo-run Google cafeterias, workers make $15 an hour and pay premiums in the hundreds of dollars, Taylor said."

Chess Is in Chaos Over Suspicion That a Player Cheated Against Magnus Carlsen (wsj.com) 86

When the world champion withdrew from a major tournament after a stunning loss, it ignited suspicions of foul play. Hans Moke Niemann, his opponent, denied any wrongdoing. Chaos ensued. The Wall Street Journal reports: Magnus Carlsen's 53-game unbeaten streak had been over for only a few hours when the reigning chess world champion made a move that indicated something was off. Carlsen had lost to 19-year-old American grandmaster Hans Moke Niemann at a prestigious tournament in St. Louis called the Sinquefield Cup when he announced, without explanation, that he was withdrawing from the whole event. The chess world was quick to read the tea leaves. "I think Magnus believes that Hans probably is cheating," said Hikaru Nakamura, an American grandmaster ranked No. 6 in the world, who added that the allegation remains "unproven." What has followed since Carlsen's exit is a supercharged scandal that is short on details and long on breathless speculation.

Carlsen, the world's top player, has said nothing publicly other than a not-so-cryptic tweet in which famous soccer manager Jose Mourinho protests the result of a match by saying: "If I speak, I am in big trouble." A spokesperson for Carlsen didn't respond to a request for comment. Niemann forcefully denied ever cheating at over-the-board chess -- while also conceding that he has previously cheated online. Tournament organizers, meanwhile, instituted additional fair play protocols. But their security checks, including game screening of Niemann's play by one of the world's leading chess detectives, the University at Buffalo's Kenneth Regan, haven't found anything untoward.

The controversy gained such momentum that top grandmasters are taking sides. In one camp are the chess professionals legitimizing the allegation and jumping to Carlsen's defense. In the other are the players who view the whole thing as a witch hunt. One competitor, Wesley So, said he could hardly sleep because of the drama. Another, Ian Nepomniachtchi, said that stamping out cheating completely would require extraordinary measures -- such as "playing naked in a locked room" to make sure no one was carrying any secret buzzers or other devices. "I don't see this happening," added Nepomniachtchi, who was Carlsen's last challenger for the World Chess Championship. The Russian had already expressed his surprise at Niemann's victory over Carlsen, calling it "more than impressive."

BlackRock, Which Manages Over $10 Trillion, Strikes Back at ESG Critics (axios.com) 114

Investment giant BlackRock is rebutting Republican politicians over its ESG investment policies, arguing that its critics are wrong on both the science and the cents. Axios: Private equity and other investment fund managers should pay close attention, because they could be next in the line of fire. Last month, 18 state attorneys general sent a letter to BlackRock, essentially arguing that its goal of moving toward a net-zero economy is in conflict with its fiduciary duty. Two states, Texas and West Virginia, also banned state entities from doing business with BlackRock, arguing (incorrectly) that the firm boycotts fossil fuel company investments.

Axios' Alayna Treene reports that the BlackRock blowback is part of a coordinated lobbying effort, writing: "The crusade against ESG investments is something many conservatives feel deeply about -- they view these companies as cultural enemies who are misusing investment funds to promote pro-climate policies... House Republicans plan to make an assault on ESG a central part of their legislative and investigative agenda if they take back the majority in November's midterms." BlackRock yesterday responded to the AG's letter, with a 10-page letter of its own. After again disputing the "boycott" accusations, the firm wrote: "We believe investors and companies that take a forward-looking position with respect to climate risk and its implications for the energy transition will generate better long-term financial outcomes." BlackRock is the world's largest asset manager, and its CEO Larry Fink has been very outspoken about ESG initiatives (with declining emphasis as the acronym progresses). In other words, it's a juicy target.

Former Disney CEO Says Company Found a 'Substantial Portion' of Twitter Users Were Not Real When It Evaluated Acquisition in 2016 (vox.com) 81

Bob Iger, former Disney CEO, explained on Wednesday why Disney didn't acquire Twitter in 2016. He said: "We enter the process immediately, looking at Twitter as the solution: a global distribution platform. It was viewed as sort of a social network. We were viewing it as something completely different. We could put news, sports, entertainment, [and] reach the world. And frankly, it would have been a phenomenal solution, distribution-wise. Then, after we sold the whole concept to the Disney board and the Twitter board, and we're really ready to execute -- the negotiation was just about done -- I went home, contemplated it for a weekend, and thought, 'I'm not looking at this as carefully as I need to look at it.' Yes, it's a great solution from a distribution perspective. But it would come with so many other challenges and complexities that as a manager of a great global brand, I was not prepared to take on a major distraction and having to manage circumstances that weren't even close to anything that we had faced before. Interestingly enough, because I read the news these days, we did look very carefully at all of the Twitter users -- I guess they're called users? -- and we at that point estimated with some of Twitter's help that a substantial portion -- not a majority -- were not real. I don't remember the number but we discounted the value heavily. But that was built into our economics. Actually, the deal that we had was pretty cheap."

Facebook Engineers: We Have No Idea Where We Keep All Your Personal Data (theintercept.com) 69

An anonymous reader quotes a report from The Intercept: In March, two veteran Facebook engineers found themselves grilled about the company's sprawling data collection operations in a hearing for the ongoing lawsuit over the mishandling of private user information stemming from the Cambridge Analytica scandal. The hearing, a transcript of which was recently unsealed (PDF), was aimed at resolving one crucial issue: What information, precisely, does Facebook store about us, and where is it? The engineers' response will come as little relief to those concerned with the company's stewardship of billions of digitized lives: They don't know.

The admissions occurred during a hearing with special master Daniel Garrie, a court-appointed subject-matter expert tasked with resolving a disclosure impasse. Garrie was attempting to get the company to provide an exhaustive, definitive accounting of where personal data might be stored in some 55 Facebook subsystems. Both veteran Facebook engineers, with according to LinkedIn two decades of experience between them, struggled to even venture what may be stored in Facebook's subsystems. "I'm just trying to understand at the most basic level from this list what we're looking at," Garrie asked. "I don't believe there's a single person that exists who could answer that question," replied Eugene Zarashaw, a Facebook engineering director. "It would take a significant team effort to even be able to answer that question." When asked about how Facebook might track down every bit of data associated with a given user account, Zarashaw was stumped again: "It would take multiple teams on the ad side to track down exactly the -- where the data flows. I would be surprised if there's even a single person that can answer that narrow question conclusively." [...]

Facebook's stonewalling has been revealing on its own, providing variations on the same theme: It has amassed so much data on so many billions of people and organized it so confusingly that full transparency is impossible on a technical level. In the March 2022 hearing, Zarashaw and Steven Elia, a software engineering manager, described Facebook as a data-processing apparatus so complex that it defies understanding from within. The hearing amounted to two high-ranking engineers at one of the most powerful and resource-flush engineering outfits in history describing their product as an unknowable machine. The special master at times seemed in disbelief, as when he questioned the engineers over whether any documentation existed for a particular Facebook subsystem. "Someone must have a diagram that says this is where this data is stored," he said, according to the transcript. Zarashaw responded: "We have a somewhat strange engineering culture compared to most where we don't generate a lot of artifacts during the engineering process. Effectively the code is its own design document often." He quickly added, "For what it's worth, this is terrifying to me when I first joined as well."

YouTube Acquisition Nearly Fell Apart When Cofounder Found That a Google Employee Snooped on Revenue Figures (businessinsider.com) 9

An anonymous reader shares a report: On the eve of Google's acquisition of YouTube in 2006, the video site's cofounder Chad Hurley discovered that a Google ad manager had snooped on YouTube's revenue figures. Hurley was so irked by the invasion of YouTube's business that he threatened to walk away from the deal, a new book about YouTube's founding reveals. Google's CEO at the time, Eric Schmidt, was able to calm Hurley down enough to close the $1.65 billion deal -- a deal that became a pivot point in the development of the modern internet. The previously unreported episode comes from the book "Like, Comment, Subscribe: Inside YouTube's Chaotic Rise to World Domination" by the Bloomberg reporter Mark Bergen.

Problems Delay Launch of NASA's SLS Rocket - Again (cnet.com) 78

With 8.8 million pounds of thrust, NASA's SLS would've been the most powerful rocket ever launched into space, notes the Orlando Sentinel.

But instead on Saturday morning, "NASA scrubbed its second attempt to launch the Artemis I mission into lunar orbit..." reports CNET. "During a press conference later in the day, Jim Free, an associate administrator at NASA Headquarters, said we shouldn't expect to see a third attempt within this launch period, which culminates Tuesday." (Though the mission manager the next launch attempt could be as late as mid-October.)

"This time, the culprit was a liquid hydrogen leak that showed up while the team was loading the rocket's core stage...." According to the space agency, the leak occurred "while loading the propellant into the core stage of the Space Launch System rocket" and that "multiple troubleshooting efforts to address the area of the leak, by reseating a seal in the quick disconnect where liquid hydrogen is fed into the rocket, did not fix the issue."

This is the second time the Artemis I mission has been delayed. Liftoff attempt No. 1 was scheduled for Monday, but launch director Charlie Blackwell-Thompson had to call a scrub then as well, because of an unyielding problem with what's known as an engine bleed test. (This process is meant to allow the engines to chill to the right temperature by releasing a small amount of the fuel).

"We were unable to get the engines within the thermal conditions required to commit to launch," Artemis mission manager Mike Sarafin said during a press conference on Tuesday. "In combination with that, we also had a bent valve issue on the core stage, and it was at that point that the team decided to knock off the launch attempt for that day."

Intel Details 12th Gen Core SoCs Optimized For Edge Applications (theregister.com) 6

Intel has made available versions of its 12th-generation Core processors optimized for edge and IoT applications, claiming the purpose-built chips enable smaller form factor designs, but with the AI inferencing performance to analyze data right at the edge. The Register reports: The latest members of the Alder Lake family, the 12th Gen Intel Core SoC processors for IoT edge (formerly Alder Lake PS) combine the performance profile and power envelope of the mobile chips but the LGA socket flexibility of the desktop chips, according to Intel, meaning they can be mounted directly on a system board or in a socket for easy replacement. Delivered as a multi-chip package, the new processors combine the Alder Lake cores with an integrated Platform Controller Hub (PCH) providing I/O functions and integrated Iris Xe graphics with up to 96 graphics execution units. [...]

Intel VP and general manager of the Network and Edge Compute Division Jeni Panhorst said in a statement that the new processors were designed for a wide range of vertical industries. "As the digitization of business processes continues to accelerate, the amount of data created at the edge and the need for it to be processed and analyzed locally continues to explode," she said. Another key capability for managing systems deployed in edge scenarios is that these processors include Intel vPro features, which include remote management capabilities built into the hardware at the silicon level, so an IT admin can reach into a system and perform actions such as changing settings, applying patches or rebooting the platform.

The chips support up to eight PCIe 4.0 lanes, and four Thunderbolt 4/USB4 lanes, with up to 64GB of DDR5 or DDR4 memory, and the graphics are slated to deliver four 4K displays or one 8K display. Operating system support includes Windows 10 IoT Enterprise 2021 Long Term Servicing Channel (LTSC) and Linux options. Intel said the new SoCs are aimed at a broad range of industries, including point-of-sale kit in the retail, banking, and hospitality sectors, industrial PCs and controllers for the manufacturing industry, plus healthcare.

Dashlane Is Ready To Replace All Your Passwords With Passkeys (theverge.com) 37

Dashlane announced today that it's integrating passkeys into its cross-platform password manager. "We said, you know what, our job is to make security simple for users," says Dashlane CEO JD Sherman, "and this is a great tool to do that. So we should actually be thinking about ushering in this passwordless era." The Verge reports: Passwords are dying, long live passkeys. Practically the entire tech industry seems to agree that hexadecimal passwords need to die, and that the best way to replace them is with the cryptographic keys that have come to be known as passkeys. Basically, rather than having you type a phrase to prove you're you, websites and apps use a standard called WebAuthn to connect directly to a token you have saved -- on your device, in your password manager, ultimately just about anywhere -- and authenticate you automatically. It's more secure, it's more user-friendly, it's just better. The transition is going to take a while, though, and even when you can use passkeys, it'll be a while before all your apps and websites let you do so.

Going forward, Dashlane users can start to set up passkeys to log into sites and apps where they previously would have created passwords. And whereas systems like Apple's upcoming implementation in iOS 16 will often involve taking a picture of a QR code to log in, Dashlane says it can make the process even simpler because it has apps for most platforms and an extension for most browsers.

A Global Envelope Shortage Weighs on Canadian Institutions (thelogic.co) 51

An anonymous reader shares a report: Matt Stockburn already knew paper supplies were running short when the Toronto city clerk's office, where he works as a manager, received a notice from its envelope supplier to expect shipment delays. Long-term disruptions to the pulp and paper industry coupled with more recent supply-chain issues triggered a global shortage of envelopes this year. It was a matter of time before an institution as reliant on paper correspondence as a municipal government would feel the effect. "For the envelopes, it really wasn't until June, when all of a sudden we seemed to be facing some shortages," said Stockburn. For the Toronto clerk's office, a scarcity of #10 windowed envelopes -- standard for business mail -- put its legislative mandate to inform residents about city business that affects them at risk. To meet those obligations, it sends about 14,000 pieces of mail each month. More broadly, the supply shortfall raises questions about why many institutions still rely on snail mail to communicate critical information to the public and clients.

Engineers Solve Data Glitch On NASA's Voyager 1 (nasa.gov) 60

A critical system aboard the probe was sending garbled data about its status. Engineers have fixed the issue but are still seeking the root cause. NASA reports: Engineers have repaired an issue affecting data from NASA's Voyager 1 spacecraft. Earlier this year, the probe's attitude articulation and control system (AACS), which keeps Voyager 1's antenna pointed at Earth, began sending garbled information about its health and activities to mission controllers, despite operating normally. The rest of the probe also appeared healthy as it continued to gather and return science data. The team has since located the source of the garbled information: The AACS had started sending the telemetry data through an onboard computer known to have stopped working years ago, and the computer corrupted the information.

Suzanne Dodd, Voyager's project manager, said that when they suspected this was the issue, they opted to try a low-risk solution: commanding the AACS to resume sending the data to the right computer. Engineers don't yet know why the AACS started routing telemetry data to the incorrect computer, but it likely received a faulty command generated by another onboard computer. If that's the case, it would indicate there is an issue somewhere else on the spacecraft. The team will continue to search for that underlying issue, but they don't think it is a threat to the long-term health of Voyager 1.

Google Play To Ban Android VPN Apps From Interfering With Ads (theregister.com) 36

An anonymous reader quotes a report from The Register: Google in November will prohibit Android VPN apps in its Play store from interfering with or blocking advertising, a change that may pose problems for some privacy applications. The updated Google Play policy, announced last month, will take effect on November 1. It states that only apps using the Android VPNService base class, and that function primarily as VPNs, can open a secure device-level tunnel to a remote service. Such VPNs, however, cannot "manipulate ads that can impact apps monetization."

The rules appear to be intended to deter data-grabbing VPN services, such as Facebook's discontinued Onavo, and to prevent ad fraud. The T&Cs spell out that developers must declare the use of VPNservice in their apps' Google Play listing, must encrypt data from the device to the VPN endpoint, and must comply with Developer Program Policies, particularly those related to ad fraud, permissions, and malware.

Blokada, a Sweden-based maker of an ad-blocking VPN app, worries this rule will hinder at least the previous iteration of its software, v5, and other privacy-oriented software. "Google claims to be cracking down on apps that are using the VPN service to track user data or rerouting user traffic to earn money through ads," Reda Labdaoui, marketing and sales manager at Blokada, wrote last week in a a forum post. "However, these policy changes also apply to apps that use the service to filter traffic locally on the device." Labdaoui suggests Blokada v6, which launched in June, should not be affected because it does filtering in the cloud without violating Google's device policies. But other apps may not be so fortunate.

Twitter Is Becoming a Podcast App (theverge.com) 16

Twitter has launched a test version of Twitter Spaces today that includes podcasts, "letting you listen to full shows through curated playlists based on your interests," reports The Verge. From the report: The redesigned Spaces tab opens with Stations, topic-based playlists combining podcast episodes pulled from RSS with Twitter's social audio events and recordings. It functions like a Pandora station but for spoken word and is pretty different from the a la carte listening podcast consumers are used to on Apple Podcasts or Spotify. Live and upcoming spaces are still in the tab, further down the page. The test will roll out to a random group of users across the world, initially only in English. The more users listen, the more tailored the audio Stations will become. But Twitter isn't starting from square one -- the company is relying on what it already knows about its users' interests to curate the playlists. It'll draw from the interests of people they follow, as well.

"What we're really trying to capture here is as if it's like another user recommending you something," Twitter senior product manager Evan Jones, who focuses on audio, told Hot Pod. Podcast discovery is notoriously difficult, limited either to top 100 charts, hand-picked selections on apps, or -- more often than not -- word of mouth. No platform has managed to crack it, yet. It's easy to imagine the promotional possibilities around being able to share and listen to podcasts in the same app, but it's not quite there yet. The test does not yet have a clipping capability, and listening can only happen in the Spaces tab, not on the timeline. That being said, Spaces has a clipping feature that could be applied to podcasts at some point.

Google Experiences Hundreds of Covid Cases After Return-to-Office Mandate (cnbc.com) 227

"Google employees are receiving regular notifications from management of Covid-19 infections," CNBC report Friday — "causing some to question the company's return-to-office mandates." The employees, who spoke with CNBC on the condition of anonymity, said since they have been asked to return to offices, infections notifications pop up in their email inboxes regularly....

The company began requiring most employees to return to physical offices at least three days a week in April. Since then, staffers have pushed back on the mandate after they worked efficiently for so long at home while the company enjoyed some of its fastest revenue growth in 15 years. Google has offered full-time employees the option to request permanent remote work, but it's unclear how many workers have been approved.

Google's Covid-19 outbreak in Los Angeles is currently the largest of any employer in LA., according to the city's public health dashboard. Deadline.com first reported that the tech giant's trendy Silicon Beach campus in Venice, Calif., recorded 145 infections while 135 cases were recorded at the company's large Playa Vista campus.

Staffers have been filling Memegen, an internal company image-sharing site, with memes about the increased number of exposure notifications they're receiving. One meme, which was upvoted 2,840 times, showed a photo of an inbox with the email subject from a San Francisco-based facilities manager stating "We're so excited to see you back in the office!" and a subsequent email subject line stating "Notification of Confirmed COVID-19 Case...."

Some employees said they received a spike in notifications from the Mountain View, Calif. headquarters and in San Francisco offices after the company held a return-to-office celebration, where Grammy award-winning artist Lizzo performed for thousands of employees at the Shoreline Amphitheater, near Google's main campus.

Defending the safety of working on-site, a Google spokesperson told CNBC they hadn't been experiencing a sudden recent spike in their Covid cases, arguing that instead the hundreds of Covid cases had been occurring over "the last few months."

Heroku Announces Plans To Eliminate Free Plans, Blaming 'Fraud and Abuse' (techcrunch.com) 9

After offering them for over a decade, Heroku announced this week that it will eliminate all of its free services -- pushing users to paid plans. From a report: Starting November 28, the Salesforce-owned cloud platform as a service will stop providing free product plans and shut down free data services and soon (on October 26) will begin deleting inactive accounts and associated storage for accounts that have been inactive for over a year. In a blog post, Bob Wise, Heroku general manager and Salesforce EVP, blamed "abuse" on the demise of the free services, which span the free plans for Heroku Dynos and Heroku Postgres as well as the free plan for Heroku Data for Redis.

[...] Wise went on to note that Heroku will be announcing a student program at Salesforce's upcoming Dreamforce conference in September, but the details remain a mystery at this point. For the uninitiated, Heroku allows programmers to build, run and scale apps across programming languages including Java, PHP, Scala and Go. Salesforce acquired the company for $212 million in 2010 and subsequently introduced support for Node.js and Clojure and Heroku for Facebook, a package to simplify the process of deploying Facebook apps on Heroku infrastructure. Heroku claims on its website that it's been used to develop 13 million apps to date.

Meta AI and Wikimedia Foundation Build an ML-Powered, Citation-Checking Bot (digitaltrends.com) 17

Digital Trends reports: Working with the Wikimedia Foundation, Meta AI (that's the AI research and development research lab for the social media giant) has developed what it claims is the first machine learning model able to automatically scan hundreds of thousands of citations at once to check if they support the corresponding claims....

"I think we were driven by curiosity at the end of the day," Fabio Petroni, research tech lead manager for the FAIR (Fundamental AI Research) team of Meta AI, told Digital Trends. "We wanted to see what was the limit of this technology. We were absolutely not sure if [this AI] could do anything meaningful in this context. No one had ever tried to do something similar [before]."

Trained using a dataset consisting of 4 million Wikipedia citations, Meta's new tool is able to effectively analyze the information linked to a citation and then cross-reference it with the supporting evidence.... Just as impressive as the ability to spot fraudulent citations, however, is the tool's potential for suggesting better references. Deployed as a production model, this tool could helpfully suggest references that would best illustrate a certain point. While Petroni balks at it being likened to a factual spellcheck, flagging errors and suggesting improvements, that's an easy way to think about what it might do.

The Problem of Nuclear Waste Disposal - and How Finland Solved It (arstechnica.com) 146

"Even if all nuclear power plants were shut down today, there's a mountain of radioactive waste waiting to be disposed of," reports Ars Technica. "Yet only Finland has an approved solution for nuclear waste disposal, while projects in the US, UK, and Germany have failed for decades, and progress is also slow in other countries."

So how did Finland construct a safe nuclear waste repository? Ars Technica asked Antti Mustonen, who's a research manager with Posiva, the organization in charge of the Finnish repository: Finland has a lot of hard crystalline bedrock and many places that are potentially suitable for a repository. The country eventually chose an island on the Baltic coast for its Onkalo repository, and it hopes to seal off the first tunnel of nuclear waste sometime around 2025....

Even after it has cooled in ponds for decades, spent nuclear fuel gives out heat by radioactive decay, raising the temperature near the waste canisters. This heat could potentially corrode the canisters, compromise the bentonite, or even crack the rock face. Therefore, the Finnish and Swedish designs separate individual waste canisters in their own disposal shafts to avoid excessive heat buildup.... Posiva is currently conducting a long-term, full-sized demonstration using heaters in dummy canisters surrounded by bentonite and temperature probes. After three years, the temperature at the canister boundary is about 70Â C, Mustonen said. A similar test in Switzerland lasted 18 years and found that bentonite "remains suitable as a sealing material" up to at least 100 degrees C....

But to project how the rock and groundwater will affect humans living near the site in future millennia, the scientists must model that numerically using the tests and data as the starting point. "We have modeled to that million years... with different scenarios and what the likely releases [are], and it seems that the releases are acceptable," Mustonen told me.... Scientists then project what will happen to the waste over the next million years, assuming everything works as planned. They also model for several "what if" scenarios. This projection includes looking at the stresses and groundwater pressures caused by possibilities like being buried deep under a future ice sheet and then having that ice sheet melt away, sea level changes, changes in groundwater chemistry, and failures of canisters. At Onkalo, even in the worst case, scientists calculate that the maximum dose released to humans would be one-tenth of the regulatory limit, which itself is about a hundredth of the normal dose that Finns receive every year.

But the article also asks what Finland's experience can teach other countries. One person who worked on America's unsuccessful Yucca Mountain project was Dr. Jane Long, former associate director for energy and environment at Lawrence Livermore National Laboratory. Long tells the site that "They should have set requirements for an inherently safe site and then investigated whether the site met the requirements instead of choosing the site for political reasons and then trying to show the site was suitable."

And they seem to agree in Finland: "More than the geology, I think it's socio-economic aspects" that determine if a project can go ahead, Mustonen told me. A key lesson is that the top-down designation of sites for nuclear waste disposal has generally failed. The UK failed in 1987, 1997, and 2013. In the US, politicians campaigned against the Yucca Mountain project, characterizing its authorization as the "Screw Nevada Bill...."

Yucca Mountain's wasted $15 billion pales in comparison to the roughly $50 billion in damages that American taxpayers have had to pay to nuclear utilities because the government was unable to honor its commitment to receive nuclear waste by 1998. Meanwhile, more waste is piling up.

The James Webb Space Telescope Runs JavaScript, Apparently (theverge.com) 60

It turns out that JavaScript had a hand in delivering the stunning images that the James Webb Space Telescope has been beaming back to Earth. From a report: I mean that the actual telescope, arguably one of humanity's finest scientific achievements, is largely controlled by JavaScript files. Oh, and it's based on a software development kit from 2002. According to a manuscript (PDF) for the JWST's Integrated Science Instrument Module (or ISIM), the software for the ISIM is controlled by "the Script Processor Task (SP), which runs scripts written in JavaScript upon receiving a command to do so." The actual code in charge of turning those JavaScripts (NASA's phrasing, not mine) into actions can run 10 of them at once.

The manuscript and the paper (PDF) "JWST: Maximizing efficiency and minimizing ground systems," written by the Space Telescope Science Institute's Ilana Dashevsky and Vicki Balzano, describe this process in great detail, but I'll oversimplify a bit to save you the pages of reading. The JWST has a bunch of these pre-written scripts for doing specific tasks, and scientists on the ground can tell it to run those tasks. When they do, those JavaScripts will be interpreted by a program called the script processor, which will then reach out to the other applications and systems that it needs to based on what the script calls for. The JWST isn't running a web browser where JavaScript directly controls the Mid-Infrared Instrument -- it's more like when a manager is given a list of tasks (in this example, the JavaScripts) to do and delegates them out to their team.

An anonymous reader shares a report: It's been just over five years since Google announced at Google I/O 2017 that it would make Kotlin, the statically typed language for the Java Virtual Machine first developed by JetBrains, a first-class language for writing Android apps. Since then, Google took this a step further by making Kotlin its preferred language for writing Android apps in 2019 -- and while plenty of developers still use Java, Kotlin is quickly becoming the default way to build apps for Google's mobile operating system. Back in 2018, Google and JetBrains also teamed up to launch the Kotlin Foundation.

Earlier this week, I sat down with Google's James Ward, the company's product manager for Kotlin, to talk about the language's role in the Android ecosystem and beyond, as well as the company's future plans for it. It's no surprise that Google's hope is that over time, all Android developers will switch over to Kotlin. "There is still quite a bit of Java still happening on Android," Ward said. "We know that developers are generally more satisfied with Kotlin than with Java. We know that they're more productive, the quality of applications is higher and so getting more of those people to move more of their code over has been a focus for us. The interoperability of Kotlin ... with Java has made it that people can kind of progressively move code bases over and it would be great to get to the point down the road, where just everything is all Kotlin."
