| Magnon-Based Computation Could Signal Computing Paradigm Shift Apr 1st 2023, 03:30, by BeauHD An anonymous reader quotes a report from Phys.Org: Like electronics or photonics, magnonics is an engineering subfield that aims to advance information technologies when it comes to speed, device architecture, and energy consumption. A magnon corresponds to the specific amount of energy required to change the magnetization of a material via a collective excitation called a spin wave. Because they interact with magnetic fields, magnons can be used to encode and transport data without electron flows, which involve energy loss through heating (known as Joule heating) of the conductor used. As Dirk Grundler, head of the Lab of Nanoscale Magnetic Materials and Magnonics (LMGN) in the School of Engineering explains, energy losses are an increasingly serious barrier to electronics as data speeds and storage demands soar. "With the advent of AI, the use of computing technology has increased so much that energy consumption threatens its development," Grundler says. "A major issue is traditional computing architecture, which separates processors and memory. The signal conversions involved in moving data between different components slow down computation and waste energy." This inefficiency, known as the memory wall or Von Neumann bottleneck, has had researchers searching for new computing architectures that can better support the demands of big data. And now, Grundler believes his lab might have stumbled on such a "holy grail". While doing other experiments on a commercial wafer of the ferrimagnetic insulator yttrium iron garnet (YIG) with nanomagnetic strips on its surface, LMGN Ph.D. student Korbinian Baumgaertl was inspired to develop precisely engineered YIG-nanomagnet devices. With the Center of MicroNanoTechnology's support, Baumgaertl was able to excite spin waves in the YIG at specific gigahertz frequencies using radiofrequency signals, and -- crucially -- to reverse the magnetization of the surface nanomagnets. "The two possible orientations of these nanomagnets represent magnetic states 0 and 1, which allows digital information to be encoded and stored," Grundler explains. The scientists made their discovery using a conventional vector network analyzer, which sent a spin wave through the YIG-nanomagnet device. Nanomagnet reversal happened only when the spin wave hit a certain amplitude, and could then be used to write and read data. "We can now show that the same waves we use for data processing can be used to switch the magnetic nanostructures so that we also have nonvolatile magnetic storage within the very same system," Grundler explains, adding that "nonvolatile" refers to the stable storage of data over long time periods without additional energy consumption. It's this ability to process and store data in the same place that gives the technique its potential to change the current computing architecture paradigm by putting an end to the energy-inefficient separation of processors and memory storage, and achieving what is known as in-memory computation. The research has been published in the journal Nature Communications.

Reuters reports: California Governor Gavin Newsom said as a result of the plan, "half of all heavy duty trucks sold in CA will be electric by 2035." "Time to stop playing small ball," he added. Under an executive order Newsom signed in 2020, California plans to mandate by 2045 that all operations of medium- and heavy-duty vehicles be zero emission where feasible, shifting away from diesel-powered trucks. The California Air Resources Board (CARB) had sought waivers from the Clean Air Act to set heavy-duty vehicle and engine emission standards. California has been joined by Massachusetts, New Jersey, New York, Oregon, Washington and Vermont in adopting the rules. CARB has noted heavy-duty vehicles greater than 14,000 pounds comprised 3% of vehicles on California roads, but account for more than 50% of nitrogen oxides and fine particle diesel pollution. The EPA said it is not yet approving California's request to set new regulations on pollutant exhaust emission standards for nitrogen oxide (NOx) and particulate matter for 2024 and future medium- and heavy-duty engines and vehicles. Separately, California in August moved to require all new light-duty cars and trucks sold in the state by 2035 to be either electric or plug-in electric hybrids. California needs an EPA waiver for that regulation.

Tom's Hardware reports: After asking Open AI's chatbot directly for Windows 95 keys, he received an expected reasoned refusal. YouTuber Enderman then asked the same thing but from a different angle. The result was a success which was somewhat limited by ChatGPT's ability to process natural language requests into formulas. [...] Some of the tested results were checked by attempting to activate a fresh Windows 95 install in a virtual machine. While the keys passed a casual inspection, it turns out that only about 1-in-30 keys seem to work as expected. So what is the problem with these keys? Enderman complains that "the only issue keeping ChatGPT from successfully generating valid Windows 95 keys almost every attempt is the fact that it can't count the sum of digits and it doesn't know divisibility." In the five-digit string divisible by seven section, the AI appears to provide a stream of random numbers that don't pass this simple mathematical test. The report adds: "[W]hile quizzing ChatGPT about key generating may be fun, it would have probably been more productive to manipulate the AI into writing a Python script to generate a conforming key or to DIY it."

ZDNet reports: Long lines were spotted Thursday morning at the country's airport where travelers usually would not need more than mere minutes to clear immigration. In a series of posts on Facebook and Twitter, Singapore's Immigration & Checkpoints Authority (ICA) said it was experiencing "system slowness" at several passenger clearance checkpoints, including all automated departure lanes at all terminals at Changi Airport. Selected automated systems at the Woodlands and Tuas border checkpoints, through which travelers would enter neighboring country Malaysia, also were affected. Immigration systems at coastal checkpoints were the only ones that were not disrupted. Passengers were advised to postpone non-essential travel and expect delays, as they would be redirected to manual lanes for immigration clearance. By 4pm the same day, automated immigration clearance at all checkpoints were back up and running. ICA said in a statement late-Thursday that preliminary investigations revealed a "technical glitch" had occurred during a pre-scheduled system upgrade, causing an "unanticipated system overload". This brought down the automated immigration clearance systems, which affected all departure terminals at Changi Airport and arrival terminals at Terminals 2 and 4. ICA did not provide details on the system upgrade or whether the procedure was tested before the scheduled live rollout.

Eric Xu, rotating chairman at Huawei, issued fighting words against Washington's tech export restrictions on China. "I believe China's semiconductor industry will not sit idly by, but take efforts around ... self-strengthening and self reliance," according to an official translation of Xu's comments during a press conference. "For Huawei, we will render our support to all such self-saving, self-strengthening and self reliance efforts of the Chinese semiconductor industry." The U.S. is concerned that China could use advanced semiconductors for military purposes. Huawei's Xu said these developments could boost, rather than hamper China's domestic semiconductor industry. "I believe China's semiconductor industry will get reborn under such sanctions and realize a very strong and self-reliant industry," Xu said. Last week, Huawei claimed to have completed work on electronic design automation tools for laying out and making chips down to 14nm process nodes. "But Huawei ideally needs chips of a much smaller nanometer size for more advanced applications, which they are currently finding it difficult to obtain," adds Reuters. "The company is still reeling from the effects of U.S. sanctions -- on Friday, it said net profit dropped 69% year-on-year in 2022, marking the biggest decline on record."

Reuters reports: GM's decision to stop offering those systems in future electric vehicles, starting with the 2024 Chevrolet Blazer, could help the automaker capture more data on how consumers drive and charge EVs. GM is designing the on-board navigation and infotainment systems for future EVs in partnership with Alphabet's Google. GM has been working with Google since 2019 to develop the software foundations for infotainment systems that will be more tightly integrated with other vehicle systems such as GM's Super Cruise driver assistant. The automaker is accelerating a strategy for its EVs to be platforms for digital subscription services. GM would benefit from focusing engineers and investment on one approach to more tightly connecting in-vehicle infotainment and navigation with features such as assisted driving, Edward Kummer, GM's chief digital officer, and Mike Hichme, executive director of digital cockpit experience, said in an interview. "We have a lot of new driver assistance features coming that are more tightly coupled with navigation," Hichme told Reuters. "We don't want to design these features in a way that are dependent on person having a cellphone." Buyers of GM EVs with the new systems will get access to Google Maps and Google Assistant, a voice command system, at no extra cost for eight years, GM said. GM said the future infotainment systems will offer applications such as Spotify's music service, Audible and other services that many drivers now access via smartphones. "We do believe there are subscription revenue opportunities for us," Kummer said. GM Chief Executive Mary Barra is aiming for $20 billion to $25 billion in annual revenue from subscriptions by 2030.

The issue was first highlighted by Ars Technica, and appears to be enforced for both free accounts as well as those subscribed to Google Workspace and Google One. The issue was flagged by users on Reddit as well as Google's Issue Tracker and appears to have been put in place around mid-February. The file limit in place puts a hard ceiling on the total number of files stored in Google Drive at five million items. This limit ignores file size and type, and is a simple count of the number of files in your online storage bucket. This also includes items stored in the trash (which is automatically emptied every 30 days). When that limit is reached (or if the account has already exceeded it), Google Drive shows the following message: "This account has exceeded the creation limit of 5 million items. To create more items, move items to the trash and delete them forever." One user reports having seven million items in their account prior to the limit being enforced, with their account no longer able to add any new files. Effectively, that user and anyone else in the same situation are locked out of their accounts, with the files stored now in a "read-only" mode. Google appears to have confirmed the limit to some users via support, but has yet to speak out publicly about it.

The federal government said in its 2023 budget released Tuesday that it will bring the right to repair to Canada. At the same time, it's considering a universal charging port mandate like the European Union (EU) is implementing with USB-C. The Canadian federal government's 2023 budget introduces the right to repair under the chapter "Making Life More Affordable and Supporting the Middle Class." It says that the "government will work to implement a right to repair, with the aim of introducing a targeted framework for home appliances and electronics in 2024." The government plans to hold consultations on the matter and claimed it will "work closely with provinces and territories" to implement the right to repair in Canada: "When it comes to broken appliances or devices, high repair fees and a lack of access to specific parts often mean Canadians are pushed to buy new products rather than repairing the ones they have. This is expensive for people and creates harmful waste. Devices and appliances should be easy to repair, spare parts should be readily accessible, and companies should not be able to prevent repairs with complex programming or hard-to-obtain bespoke parts. By cutting down on the number of devices and appliances that are thrown out, we will be able to make life more affordable for Canadians and protect our environment." The budget also insinuates that right-to-repair legislation can make third-party repairs cheaper than getting a phone, for example, repaired by the manufacturer, where it could cost "far more than it should." Canada's 2023 budget also revealed the government's interest in introducing a standard charging port for electronics. The budget says the government "will work with international partners and other stakeholders to explore implementing a standard charging port in Canada." It says a universal charging port could help residents save money and e-waste. "Every time Canadians purchase new devices, they need to buy new chargers to go along with them, which drives up costs and increases electronic waste," the budget says.

The company today says it has 14 million active users, but almost consistently for the last decade, its financial position has been in a slow decline -- with stagnation in its core business model, little success in efforts to diversify, declining revenues and ongoing losses. And today comes the latest chapter in that story. The Chicago-based company, which today has a market cap of just $103 million (a drop of 99.4% from its public market debut), has appointed Dusan Senkypl, a current board member, as interim CEO. Senkypl will run the company... out of the Czech Republic. His appointment is effective immediately, the company said in a statement today. He replaces Kedar Deshpande, who had been Groupon's CEO for just 15 months.

From a report: The company confirmed to TechCrunch that the test is very limited and does not apply to paid members. The move indicates that the company may be exploring the possibility of an ad-based membership option. Audible declined to comment on any specific plans. The test includes audiobooks, podcasts and Audible Originals. Audible says the test applies to a limited subsection of titles on its platform. Content providers were informed of the change and given the chance to opt out of ads. Users who are part of the test will hear a total of eight ads within a 24-hour period. Audible says it has taken additional measures to make sure that ads won't be heard too frequently within a short time span.

Now, the company has introduced a transparency center serving as a hub for safety, security and policy information. It also announced plans to release transparency reports biannually rather than just once per year and said that in 2022, it removed significantly more offensive content, including child abuse and revenge porn, than in 2021. Last year, Reddit saw a big jump in moderation and legal requests, according to its 2022 transparency report. Government and law enforcement removal account information requests were up by 51 percent and 61 percent respectively, while copyright notices jumped 43 percent. The story was similar on the moderation front. Last summer, the BBC reported that Reddit was still leaving up "thousands" of non-consensual intimate (NCII) images (aka revenge porn), despite making changes to its policy earlier in this year.

From a report: The Synopsys.ai suite promises to radically reduce development time, lower costs, improve yields, and enhance performance. The set of tools is set to be extremely useful for chips set to be made on leading-edge nodes, such as 5nm, 3nm, 2nm-class, and beyond. As chips gain complexity and adopt newer process technologies, their design and manufacturing costs escalate to unprecedented levels. Designing a reasonably complex 7 nm chip costs about $300 million (including ~ 40% for software). In contrast, the design cost of an advanced 5 nm processor exceeds $540 million (including software), according to International Business Strategies (IBS) estimates. At 3 nm, a complex GPU will cost about $1.5 billion to develop, including circa 40% for software.

So today we are taking the first step in a new era of transparency and opening much of our source code to the global community. On GitHub, you'll find two new repositories (main repo, ml repo) containing the source code for many parts of Twitter, including our recommendations algorithm, which controls the Tweets you see on the For You timeline. We're also sharing more information on our recommendation algorithm in this post on our Engineering Blog. For this release, we aimed for the highest possible degree of transparency, while excluding any code that would compromise user safety and privacy or the ability to protect our platform from bad actors, including undermining our efforts at combating child sexual exploitation and manipulation. Today's release also does not include the code that powers our ad recommendations. We also took additional steps to ensure that user safety and privacy would be protected, including our decision not to release training data or model weights associated with the Twitter algorithm at this point. Ultimately, this is our first step to be more transparent in this way, and we plan to continue sharing more code that does not present a significant risk to Twitter or people on our platform.

This includes what's known as "feature phones" -- traditional flip or slide phones that have additional features like GPS or a hotspot. "I think you can see it with certain Gen Z populations -- they're tired of the screens," said Jose Briones, dumb phone influencer and moderator of the subreddit, "r/dumbphones." "They don't know what is going on with mental health and they're trying to make cutbacks." In the U.S., feature flip phone sales were up in 2022 for HMD Global, with tens of thousands sold each month. At the same time, HMD's global feature phone sales were down, according to the company. In 2022, almost 80% of feature phone sales in 2022 came from the Middle East, Africa and India, according to Counterpoint Research. But some see that number shifting, as a contingency of young people in the U.S. revert back to dumb or minimalist phones. "In North America, the market for dumb phones is pretty much flatlined," said Moorhead. "But I could see it getting up to 5% increase in the next five years if nothing else, based on the public health concerns that are out there."

From a report: Grant Shapps, the energy and net zero secretary, on Thursday unveiled the "powering up Britain" strategy, with carbon capture and storage (CCS) at its heart, during a visit to a nuclear fusion development facility in Oxford. Shapps said the continued production of oil and gas in the North Sea was still necessary, and that the UK had a geological advantage in being able to store most of the carbon likely to be produced in Europe for the next 250 years in the large caverns underneath the North Sea. "Unless you can explain how we can transition [to net zero] without oil and gas, we need oil and gas," he said. "I am very keen that we fill those cavities with storing carbon. I think there are huge opportunities for us to do that." Shapps pointed to the $24.7bn the government is planning to spend over 20 years on developing CCS, which he said would generate new jobs and make the UK a world leader in the technology. Among the 1,000 pages of proposals to be published on Thursday will be boosts for offshore wind, hydrogen, heat pumps and electric vehicles. A green finance strategy, to be set out by the chancellor of the exchequer, Jeremy Hunt, will be aimed at mobilising private-sector money for investments in green industry, and there will be a consultation on carbon border taxes, aimed at penalising the import of high-carbon goods from overseas. But the plans contain no new government spending, and campaigners said they missed out key elements, such as a comprehensive programme of home insulation and a full lifting of the ban on new onshore wind turbines in England.
