China Hits Back at US Chip Sanctions With WTO Dispute (arstechnica.com) 39

China has hit back against sweeping US export controls on chips, filing a dispute with the World Trade Organization and escalating the tech war between the two countries. From a report: China's commerce ministry said on Monday its WTO complaint was a legal and necessary measure to defend its "legitimate rights and interests," after the US Department of Commerce introduced sanctions in early October to make it harder for China to buy or develop advanced semiconductors. "At a minimum, the case is about China pushing back on how it's perceived as an unfair actor in the global trading world," said Ben Kostrzewa, an expert on US-China trade relations at Hogan Lovells.

The complaint is the first step in a WTO mediation process, in which the case would normally be put before the Appellate Body. But that body has been suspended due to disagreements among member states, and Kostrzewa said China's complaint was unlikely to "create any legal effect" unless the group resumed its work. The move comes just weeks after US President Joe Biden and his Chinese counterpart Xi Jinping used their first in-person meeting as leaders to signal a joint desire to improve ties between the world's two biggest economies after relations plunged to a multi-decade low.

Bipartisan Group of Lawmakers Seek To Ban TikTok From the US (senate.gov) 122

A press release from the office of U.S. Senator Marco Rubio: TikTok's Chinese parent company, ByteDance, is required by Chinese law to make the app's data available to the Chinese Communist Party (CCP). From the FBI Director to FCC Commissioners to cybersecurity experts, everyone has made clear the risk of TikTok being used to spy on Americans. U.S. Senator Marco Rubio (R-FL) introduced bipartisan legislation to ban TikTok from operating in the United States.

The Averting the National Threat of Internet Surveillance, Oppressive Censorship and Influence, and Algorithmic Learning by the Chinese Communist Party Act (ANTI-SOCIAL CCP Act) would protect Americans by blocking and prohibiting all transactions from any social media company in, or under the influence of, China, Russia, and several other foreign countries of concern. U.S. Representatives Mike Gallagher (R-WI) and Raja Krishnamoorthi (D-IL) introduced companion legislation in the U.S. House of Representatives.

US Air Force Launches First Operational Hypersonic Missile (space.com) 102

The United States Air Force (USAF) has successfully tested its first prototype hypersonic missile. Space.com reports: The service's new AGM-183A Air-launched Rapid Response Weapon, or ARRW ("Arrow") is expected to be the United States military's first hypersonic weapon to reach operational status. The exact speed of the AGM-183A isn't known, although the Lockheed Martin-designed weapon is said to be based on previous test vehicles built by DARPA that have an alleged maximum speed of Mach 20, or 15,000 mph (24,000 kph). The successful ARRW test was conducted on Friday (Dec. 9) in a training range off the coast of California, according to a USAF statement released Monday (Dec. 12). "This test was the first launch of a full prototype operational missile," officials wrote in the statement. "Following the ARRW's separation from the aircraft, it reached hypersonic speeds greater than five times the speed of sound, completed its flight path and detonated in the terminal area. Indications show that all objectives were met."

According to the U.S. Air Force, the missile is designed to "hold fixed, high-value, time-sensitive targets at risk in contested environments," meaning it will be used to target pre-determined assets on the ground such as fixed missile sites, radar stations, air defense installations, infrastructure facilities or even adversary headquarters buildings -- basically anything important in a battlefield environment that can't be moved and needs to be destroyed quickly. [...] Now that the ARRW has successfully flown, it's likely the service could reevaluate its plans to scrap planned purchases of the AGM-183A. The AGM-183A is what is known as a boost-glide vehicle, which refers to warheads or projectiles that glide toward their targets after being lofted by a rocket booster.

Google Delays Start of Manifest V2 Chrome Extension Deprecation (9to5google.com) 9

An anonymous reader quotes a report from 9to5Google: Google was originally set to phase out Chrome support for old Manifest v2 extensions in 2023, but that's now being postponed. In 2021, Google announced its deprecation plans and last provided an update this September. On Friday, the company said that the "Manifest V2 deprecation timelines are under review and the experiments scheduled for early 2023 are being postponed."

The original plan called for Chrome Beta, Dev, and Canary builds to start experiments that turned off Manifest V2 extension support. Additionally, Manifest V3 would be required to get the "Featured" badge in the Chrome Web Store. After "monitoring comments from the developer community," Google identified "common challenges posed by the migration": "...specifically the service worker's inability to use DOM capabilities and the current hard limit on extension service worker lifetimes. We're mitigating the former with the Offscreen Documents API (added in Chrome 109) and are actively pursuing a solution to the latter."

Google says it's "committed to providing developers solutions to migration challenges with new functionality, bug fixes, and adequate time for adoption." With the first step delayed, Google is also "evaluating all downstream milestones as well." This includes the original June 2023 plan to start testing the deprecation in Chrome Stable. The final step in January 2024 would have been to remove all MV2 Chrome extensions from the Web Store. Google will provide an "updated phase-out plan and schedule by March of 2023." Compared to the previous iteration, Manifest V3 is prioritizing privacy, though some complain that it's at the expense of ad blockers.

Raspberry Pi Inventory Improving, Could Reach Pre-Pandemic Levels In 2023 (arstechnica.com) 55

According to CEO Eben Upton, "hundreds of thousands" of Raspberry Pi Zero, 3A+, and 4 models should show up next year. Ars Technica reports: In a "Supply chain update" blog post ("It's good news!"), CEO Eben Upton wrote that Raspberry Pi has "set aside a little over a hundred thousand units, split across Zero W, 3A+, and the 2GB and 4GB variants of Raspberry Pi 4, for single-unit sales." During the pandemic-spurred component shortage, most of the Pis produced every month were going to businesses, leaving those in need of one or two for a project refreshing rpilocator and cursing their timing. Zeros will start showing up first, then 3A+, then different models of 4. Upton acknowledged this reality (and even linked the locator) and asked that people buy only from approved resellers and consider the Pico and Pico W lines for projects that might fit, as those lines remain strong. As of this morning, a few 3A+ and CM4 models showed an optimistic green on the rpilocator spreadsheet.

Raspberry Pi will continue to serve its commercial and industrial customers, Upton wrote, but will "make sure that inventory-building behavior which would otherwise prolong the shortage for everybody else can't take place." Meanwhile, Raspberry Pi will increase the percentage of boards designated for single-unit sales. With that change and future chip allocations, Upton expects that by the end of the third quarter of 2023, things will be back to how they were before the Great Pi Shortage, with "hundreds of thousands of units available at any given time."

AI Art Apps Are Cluttering the App Store Following Lensa AI's Success (techcrunch.com) 7

An anonymous reader quotes a report from TechCrunch: Lensa's AI popularity has had a notable impact on the App Store's Top Charts. The popular photo and video editing app recently went viral over its new "magic avatars" feature, powered by the open source Stable Diffusion model, allowing users to turn their selfies into styled portraits of themselves as sci-fi, anime, or fantasy characters, among other artistic renderings. Consumer demand for the app, and for AI edits more broadly, has now pushed numerous other "AI" apps into the U.S. App Store's Top Charts. As of Monday, the top three spots on the U.S. App Store are now all held by AI photo editors, and even more AI art apps are newly ranking in the Top 100.

The No. 1 spot on the U.S. App Store, however, continues to be held by Lensa AI, which has seen 12.6 million global installs in the first 11 days of December, up 600% from the 1.8 million installs it saw during a similar time frame in November (Nov. 20 through Nov. 30), according to new data from app store intelligence firm Sensor Tower. The U.S. accounted for 3.6 million of those new December installs, estimates indicate. In fact, 8 out of the top 100 apps by downloads on the U.S. App Store were AI art apps during the Dec. 1 through Dec. 11 time frame, the firm's analysis found. Following Lensa AI, the generic-sounding app AI Art: AI Image Generator has keyword-stuffed its app's name to rank in second place, promising AI avatars and AI art from text. Dawn -- AI Avatars is in the No. 3 position, offering AI avatars that can be changed with a text prompt.

[...] In addition to highly ranking overall among iPhone apps, the U.S. App Store's Graphics & Design category is also now filled with AI art apps within its own Top Charts. Here, Dawn is the No. 1 Top Free app, followed by AI Art and Wonder to round out the top 3. Profile AI: AI Avatar Creator, Inspire -- AI Art Generator, and Dream by Wombo -- AI Art Tool are ranked 8, 9, and 10, respectively. Lesser known "AI" apps pop up as you scroll down the category's Top 50 as well, filing slots No. 14, 19, 21, 25, 27, 31, 36, 44, and 47 -- too many to list. All use the keyword "AI" in their app's name along and reference activities like "AI art" or "AI avatars." And of course, the U.S. Photo & Video category's Top Charts have several AI apps charting as well, including No. 1 Lensa, No. 5 Prequel, No. 7 Voi, No. 8 Meitu, and No. 26 FacePlay. AI app demand is not limited to the App Store, however. Many of the same apps are trending on Google Play, too. When both app stores' rankings are combined, Lensa AI remains No. 1, AI Art is No. 2, Wonder is No. 8, Meitu is No. 10, Prequel is No. 68, Dawn is No. 72, Dream is No. 77 and FacePlay is No. 90.

Poor Software Costs the US 2.4 Trillion (securitymagazine.com) 78

Software quality issues may have cost the U.S. economy $2.41 trillion in 2022. From a report: This statistic is unearthed in Synopsys's 'The Cost of Poor Software Quality in the US: A 2022 Report.' The report's findings reflect that as of 2022, the cost of poor software quality in the U.S. -- which includes cyberattacks due to existing vulnerabilities, complex issues involving the software supply chain, and the growing impact of rapidly accumulating technical debt -- have led to a build-up of historic software deficiencies. Co-sponsored by Synopsys, the report was produced by the Consortium for Information & Software Quality (CISQ), an organization developing international standards to automate software quality measurement and promoting the development and maintenance of secure, reliable, and trustworthy software.

The report highlights several key areas of CPSQ growth, including:
Cybercrime losses due to a rising number of software vulnerabilities. Losses rose 64% from 2020 to 2021 and are on track for a further 42% increase from 2021 to 2022. The quantity and cost of cybercrime incidents have been on the rise for over a decade, and now account for a sum equivalent to the world's third-largest economy after the U.S. and China.
Software supply chain problems with underlying third-party components are up significantly. This year's report shows that the number of failures due to weaknesses in open-source software components accelerated by an alarming 650% from 2020 to 2021.
Technical debt has become the largest obstacle to making changes in existing code bases. Technical debt refers to software development rework costs from the accumulation of deficiencies leaving data and systems potentially vulnerable. This year's report illustrates that deficiencies aren't being resolved, leading technical debt to increase to approximately $1.52 trillion.

UK Arrests Five For Selling 'Dodgy' Point of Sale Software (theregister.com) 23

Tax authorities from Australia, Canada, France, the UK and the USA have conducted a joint probe into "electronic sales suppression software" -- applications that falsify point of sale data to help merchants avoid paying tax on their true revenue. From a report: A Friday announcement from the Joint Chiefs of Global Tax Enforcement (known as the J5), states that the probe "resulted in the arrest of five individuals in the United Kingdom who allegedly designed and sold electronic sales suppression systems internationally." Those responsible allegedly started to export their wares during the COVID-19 pandemic.

"These dodgy sales suppression tools allow retailers to keep a separate set of books and launder the money in one transaction," explained J5 chief and Australian Taxation Office deputy commissioner John Ford. "They conceal and transfer this income anonymously, sometimes offshore."

PC Price Cuts Are Coming as Manufacturers Rethink Their Portfolios (zdnet.com) 42

An anonymous reader shares a report: According to a recent IDC forecast, the PC and tablet markets are expected to shrink. Shipments for tablets and PCs will decline almost 12% in 2022, the research firm reported, and are expected to decline further in 2023. But excess inventory is already forcing suppliers to heavily discount products and shift from the premium segment to more mid-range products, the analysts said. On the other hand, the report states that tablet and PC shipments will continue to remain above pre-pandemic levels. But uncertain economic conditions will threaten inventory and increase market saturation next year.

"The reality is that both PC and tablet makers will struggle in the coming months as not only are volumes expected to decline, but so will average selling prices," Jitesh Ubrani, IDC's research manager for mobility and consumer device trackers, said in a release. In October of this year, IDC reported that tablet shipments were down 8.8%, signaling the fifth straight quarter of the tablet market's decline. This market contraction followed two years of massive growth, which can be mostly attributed to economic factors.

Hype Around Esports Is Fading as Investors and Sponsors Dry Up (bloomberg.com) 98

The once-thriving esports industry has fallen on hard times as funding sources dwindle and signs abound that athletic competition via video games doesn't have anywhere near the earning potential investors anticipated. From a report: Sports-business billionaires and gaming executives had hopes that esports could one day could scale into an organization like the National Basketball Association. But after a boom five years ago, several prominent esports teams and organizations, particularly in the US, are contracting, the result of a broad economic downturn, a venture capital industry that's no longer willing to accept growth without profits and a crypto meltdown that has undercut a significant source of backing.

Since the summer, Team SoloMid and 100 Thieves -- the two most valuable esports organizations according to Forbes -- have terminated dozens of positions in total. In November, Evil Geniuses, one of the oldest esports groups, disbanded its North America team that competed in the highly popular game Defense of the Ancients 2 and shifted their operations to South America. Game publishers, too, are shrinking their esports operations and that's trickling down to tournament organizers, teams and players. In early November, Riot Games said it will close its official Wild Rift leagues outside of Asia next year, choosing to focus solely on the world's biggest mobile gaming market. And a popular Super Smash Bros. tournament was terminated after not getting a license from Nintendo.

Investors who were once eager to get in early on what was expected to be a booming industry are now scrutinizing the business fundamentals and not much liking what they see. In 2018, a record $4.5 billion was invested in the industry, including from private equity firms jumping in for the first time, according to a report by Deloitte. That bounty has faded and venture capital investment in esports is the lowest it's been since 2016 -- excluding 2020, when pandemic restrictions threw into question the viability of live esports tournaments -- according to data provided by PitchBook.

Support for Windows 7 and 8 Fully Ends in January, Including Microsoft Edge 81

Microsoft's Chromium-based Edge browser was an improvement over the initial version of Edge in many ways, including its support for Windows 7 and Windows 8. But the end of the road is coming: Microsoft has announced that Edge will end support for Windows 7 and Windows 8 in mid-January of 2023, shortly after those operating systems stop getting regular security updates. From a report: Support will also end for Microsoft Edge Webview2, which can use Edge's rendering engine to embed webpages in non-Edge apps. The end-of-support date for Edge coincides with the end of security update support for both Windows 7 and Windows 8 on January 10, and the end of Google Chrome support for Windows 7 and 8 in version 110. Because the underlying Chromium engine in both Chrome and Edge is open source, Microsoft could continue supporting Edge in older Windows versions if it wanted, but the company is using both end-of-support dates to justify a clean break for Edge.

Meta Kills Facebook Connectivity After Nearly a Decade (lightreading.com) 10

After almost a decade of running the operation, Meta has shut down Facebook Connectivity. From a report: Meta, formerly Facebook, confirmed to Light Reading it would fold what is now called Meta Connectivity into two other groups within the company: "Infrastructure" and "Central Products." The moves make sense considering Meta's "Infrastructure" team handles the company's work in areas such as subsea cabling. The action will not affect Meta's participation in the Telecom Infra Project (TIP), which it helped to found in 2016. That group continues to develop open and disaggregated standards for various telecom technologies.

Japan To Join US Effort to Tighten Chip Exports To China (bloomberg.com) 23

Japan and the Netherlands have agreed in principle to join the US in tightening controls over the export of advanced chipmaking machinery to China, Bloomberg News reported according to people familiar with the matter, a potentially debilitating blow to Beijing's technology ambitions. From the report: The two countries are likely to announce in the coming weeks that they'll adopt at least some of the sweeping measures the US rolled out in October to restrict the sale of advanced semiconductor manufacturing equipment, according to the people, who asked not to be named because they are not authorized to speak publicly on the matter. The Biden administration has said the measures are aimed at preventing Beijing's military from obtaining advanced semiconductors.

The three-country alliance would represent a near-total blockade of China's ability to buy the equipment necessary to make leading-edge chips. The US rules restricted the supply from American gear suppliers Applied Materials, Lam Research and KLA. Japan's Tokyo Electron and Dutch lithography specialist ASML Holding are the two other critical suppliers that the US needed to make the sanctions effective, making their governments' adoption of the export curbs a significant milestone. "There's no way China can build a leading-edge industry on their own. No chance," said Sanford C. Bernstein analyst Stacy Rasgon.

OSnews Decries 'The Mass Extinction of Unix Workstations' (osnews.com) 284

Anyone remember the high-end commercial UNIX workstations from a few decades ago — like from companies like IBM, DEC, SGI, and Sun Microsystems?

Today OSnews looked back — but also explored what happens when you try to buy one today> : As x86 became ever more powerful and versatile, and with the rise of Linux as a capable UNIX replacement and the adoption of the NT-based versions of Windows, the days of the UNIX workstations were numbered. A few years into the new millennium, virtually all traditional UNIX vendors had ended production of their workstations and in some cases even their associated architectures, with a lacklustre collective effort to move over to Intel's Itanium — which didn't exactly go anywhere and is now nothing more than a sour footnote in computing history.

Approaching roughly 2010, all the UNIX workstations had disappeared.... and by now, they're all pretty much dead (save for Solaris). Users and industries moved on to x86 on the hardware side, and Linux, Windows, and in some cases, Mac OS X on the software side.... Over the past few years, I have come to learn that If you want to get into buying, using, and learning from UNIX workstations today, you'll run into various problems which can roughly be filed into three main categories: hardware availability, operating system availability, and third party software availability.

Their article details their own attempts to buy one over the years, ultimately concluding the experience "left me bitter and frustrated that so much knowledge — in the form of documentation, software, tutorials, drivers, and so on — is disappearing before our very eyes." Shortsightedness and disinterest in their own heritage by corporations, big and small, is destroying entire swaths of software, and as more years pass by, it will get ever harder to get any of these things back up and running.... As for all the third-party software — well, I'm afraid it's too late for that already. Chasing down the rightsholders is already an incredibly difficult task, and even if you do find them, they are probably not interested in helping you, and even if by some miracle they are, they most likely no longer even have the ability to generate the required licenses or release versions with the licensing ripped out. Stuff like Pro/ENGINEER and SoftWindows for UNIX are most likely gone forever....

Software is dying off at an alarming rate, and I fear there's no turning the tide of this mass extinction.

The article also wonders why companies like HPE don't just "dump some ISO files" onto an FTP server, along with patch depots and documentation. "This stuff has no commercial value, they're not losing any sales, and it will barely affect their bottom line.

WSJ: Europe, US Need Grand Bargain on Chips and EVs to Counter China (bangkokpost.com) 61

South Korea, Japan and the EU see America's electric-vehicle subsidies as discriminating against non-American manufacturers, and are "rebuffing" restrictions on exporting sensitive semiconductor technology to China, reports the Wall Street Journal. (Alternate URL here.)

The EU's executive arm complains that newly-passed U.S. subsidies constitute "a market-distorting boost, tilting the global level playing field and turning a common global objective — fighting climate change — into a zero-sum game." There's a grand bargain to be had here: the U.S. makes its allies eligible for its EV subsidies and those allies join its semiconductor controls. The politics and details of any such bargain are, of course, difficult, maybe insurmountable. Yet such an accommodation, if it happened, would entail almost no economic cost to the U.S. or its allies — and potentially large long-term gains....

The U.S. Treasury Department could use its administrative discretion to phase in the Inflation Reduction Act's provisions or define content to allow more of these manufacturers' products to qualify. It could also interpret "free-trade agreement" to include not just formal bilateral treaties but broader pacts such as the WTO Government Procurement Agreement or the Minerals Security Partnership, both of which include Japan, South Korea, and the European Union but not mainland China or Russia.

If the U.S. bends to its allies on electric vehicles, its allies should bend to the U.S. on semiconductors.... Meanwhile, business as usual entails its own — potentially significant — costs. China's long-term goal is self sufficiency in all advanced technology, including semiconductors. It does business with Western companies until its own national champions can displace them first in China and then abroad. It has already followed the script in high-speed rail, power generation and telecommunications equipment. If China has its way, the market share that South Korean, Japanese and European semiconductor companies are trying to preserve will be gone a few decades from now.

Is This Nature App the Key To Saving Civilization? (buffalonews.com) 59

Slashdot reader biobricks shares this report from the New York Times. (Alternate URLs here and here.) When Merav Vonshak wanted to identify the gelatinous blob she had photographed floating in a shallow pool of water on a family vacation, she bypassed a wildlife-related website too often beset by bickering. She gave no consideration to brand-name social media platforms known for snark or misinformation.

Instead she uploaded the picture to a site called iNaturalist, where strangers have come together to pursue a very specific type of truth: the correct scientific classification for the living things they photograph in the wild or the backyard. They have so far processed about 90 million, with at least a quarter completed in 2022 alone.... Like many iNaturalist users, Dr. Vonshak, 45, invokes utopian metaphors not typically associated with social media to describe the platform. ("It reminds me of "Star Trek," you know? Our society as I would wish it would be.") Indeed, while examining mud snakes and mosses, it has dawned on many of the iNaturalist faithful that maybe they are on to something much bigger — a model for using the web that is governed by cooperation, not combat....

A not-for-profit initiative of the California Academy of Sciences and the National Geographic Society, iNaturalist says it aims to connect people to nature through technology. And the site's species-level identifications have been cited in thousands of scientific papers. But in a moment that can feel like everything is subject to dispute — the cause of inflation, the nature of gender, the legitimacy of an election — iNaturalist has also gained recognition as a rare place on the internet where people with different points of view manage to forge agreement on what constitutes reality.... And some social network scholars say its growth holds lessons for improved communication....

With help from a computer-vision algorithm, users who upload an observation typically suggest an identification. Others can then add their own nomination in the comments. As soon as a two-thirds majority emerges, the record receives a "community ID," which can be overwritten anytime the majority shifts.... The growth of iNaturalist has been fueled in part by technologies that have democratized the act of documenting and identifying species. Its machine-learning algorithm, trained on the identifications of iNaturalist users over the last decade, now reliably recognizes some 70,000 types of organisms and provides real-time suggestions. Better smartphone cameras have helped, as have inexpensive macro-lens attachments and the ubiquity of wireless internet access.

But the article also applauds the site's "explicit aim of collaboration and consensus" — 120 million "observations" have been posted just this year — each a chance to experience one more small collective triumph.

In the article one 32-year-old describes the site as "the place where I feel like I interact with strangers and work towards the common good."

Can a 'Virtual' Manual Transmission Bring the Stick Shift to Electric Cars? (evo.co.uk) 376

Lexus is apparently working on a "virtual" manual transmission, reports the Verge, "to find out if the stick shift can survive the electric revolution..." British car enthusiast publication Evo reported this week that Lexus, which now leads Toyota's high-performance EV efforts, is developing a kind of shifting system that mimics the feel of a clutch and a stick shift in an electric car. Of course, it comes without the traditional mechanical connections for such a transmission because an EV doesn't need those things, but it mimics the motions involved with three-pedal driving. The company has even been showing it off on a special version of the Lexus UX 300e, an electric crossover not sold in the U.S.

Evo reports the "transmission" has an unconnected gear stick and clutch coupled to the electric powertrain, with fake internal combustion sounds and software that augments the electric torque output. In other words, it's a full-on pretend manual in an EV, complete with the "vroom vroom" sounds.... If this electric transformation really happens, being an enthusiast in the future could mean paying big bucks to simulate the things that got lost along the way.

Their headline puts it less charitably. ("Lexus could save the stick shift for EVs, if drivers are willing to pretend.")

But Evo writes that Toyota's ultimate goal is "making EVs more engaging to drive," noting it's also equipped with haptic drivers "to generate 'feel.'" Clumsy shifts will be accurately translated; you'll even be able to stall it. Toyota says it'll be able to theoretically recreate any engine and transmission combination through both sound and torque deliveries from the powertrain.... Takashi Watanabe, Lexus Electrified Chief Engineer, explained: "It is a software-based system, so it can be programmed to reproduce the driving experience of different vehicle types, letting the driver choose their preferred mapping...."

The sound being created from this sort of system is bound to only get better too, as other factors like vibrations through the cabin could be recreated by motors in the seats. This is a system used in BMW's latest high-end Bowers & Wilkins sound systems, which use vibrating motors in the seats to create more depth to the bass coming from its speakers.... It might not be the real thing, but in a future where we don't have a choice on the matter and have to drive an EV, it might be the next best thing...

Google's Dart Programming Language Soon Won't Take 'Null' For an Answer (theregister.com) 43

"When the third major release of the Dart programming language debuts in mid-2023, null values will no longer be allowed where they're not expected," reports the Register: Null in this context is an assignment value indicating the absence of a value or referenced object.... Dart, an object-oriented, garbage-collected C-like language that once aspired to replace JavaScript, supported sound null safety — a way to prevent errors from accessing variables set to null — as of version 2.12. But it maintained modes for running code without null safety or with partial null safety. Dart 3 will no longer entertain those suboptimal possibilities.

"Our next release, Dart 3, completes the journey to a fully sound null safe language," explained Michael Thomsen, product manager on Dart and Flutter, in a blog post. "As the last step of that journey, we're removing several historical Dart language and SDK artifacts, including removing support for running without sound null safety." Sound null safety, Thomsen explains, means that a non-nullable variable never contains a null value. Not every implementation of null safety is so certain: TypeScript, for example, is unsound — you can assign a null value to a non-null variable. C# has exceptions to its null checks. And Kotlin also has exceptions.

Dart's transition will help catch type-related bugs at compile time, and should improve code readability, maintainability, and ahead-of-time (AOT) compilation. There's a cost however. Sound null safety will be the only option so pubspec files — Dart package metadata — with an SDK constraint set for less than 2.12 will no longer resolve in Dart 3. According to Thomsen, about 85 percent of Flutter code (which is written in Dart) supports sound null safety at this point. Those with apps and packages in the remaining 15 percent are urged to adapt their code prior to Dart 3's arrival....

Following the release of Dart 3, the next significant milestone for the language is likely to be support for compiling Dart code into WebAssembly (Wasm), which will allow Flutter Web apps to run as native code in browsers.

After US Sanctions, Huawei Seeks New Revenue By Licensing Its 5G Patents to Rival (cnbc.com) 15

CNBC reports: Chinese technology giant Huawei said Friday it will license its 5G technology to rival handset maker Oppo as it looks to unlock a new revenue stream after its smartphone business was crushed by U.S. sanctions....

Huawei has a massive portfolio of over 100,000 patents globally. It is one of the top patent holders in 5G technology, which is next-generation ultra-fast mobile internet seen as key to underpinning future industries such as artificial intelligence and autonomous cars.... The company previously stated that it expected to earn revenue of $1.2 billion to $1.3 billion from licensing its intellectual property between 2019 to 2021. Huawei said that it met its intellectual property revenue expectations for 2021, but did not provide a figure.

To Pursue Climate Goals, JetBlue Switches from Carbon Offsets to Sustainable Aviation Fuels (theverge.com) 41

"JetBlue is giving up carbon offsets for its domestic flights," reports the Verge, "shifting its focus instead to sustainable aviation fuels.

"It's a step that could help the airline actually reduce its emissions rather than relying primarily on controversial carbon offsets to counteract its fossil fuel use." Back in 2020, JetBlue became the first U.S. airline to voluntarily offset greenhouse gas emissions from all of its domestic flights. That effort ends in 2023, the company announced this week. The airline now plans to effectively cut its per-seat emissions in half by 2035. For flights to take off without generating as much pollution, JetBlue says its planes will need to run on sustainable aviation fuels.
JetBlue's announcement calls the move "a science-based target approved by the Science Based Targets initiative, a coalition that defines and promotes best practices in emissions reduction targets....

"[T]his science-based target aligns with the goals of the Paris Agreement and the growing airline's own goal to reach net zero carbon emissions by 2040 — 10 years ahead of broader airline industry targets." JetBlue also recognizes how critical external partners are to decarbonizing the aviation industry and is committed to encouraging and supporting efforts by aircraft and engine manufacturers, governments, regulatory agencies, and fuel suppliers to realize their own greenhouse gas emission reduction goals. "Effectively cutting our per-seat emissions in half will require substantial change to the way we run our business today," said Robin Hayes chief executive officer, JetBlue.

"Our team is fully committed to hitting the goal, but we can't do it alone. We are calling on governments, aircraft and engine manufacturers, and fuel producers to support the development of the products and solutions that airlines need to achieve our ambitious goals...."

"The aviation industry is at a critical time in our push towards net zero. Many of these lower carbon solutions are proven, but still haven't achieved the scale needed to make a meaningful impact," said Sara Bogdan, director of sustainability and environmental social governance, JetBlue. "Encouragement of these maturing technologies is needed and the investments we make today will help shape the trajectory of these solutions as they grow to realize their fullest potential."
