FallOutBoyTonto shares a report from Ars Technica: Part of the problem with liquid cooling solutions is that they're limited by having to get the heat out of the chip and into the water in the first place. That's led some researchers to consider running the liquid through the chip itself. Now, some researchers from Switzerland have designed the chip and cooling system as a single unit, with on-chip liquid channels placed next to the hottest parts of the chip. The results are an impressive boost in heat-limited performance. There have been a number of demonstrations of on-chip liquid cooling. These typically involve a system where a device with a set of liquid channels is fused onto a chip, and a system pumps fluid through it. This can get heat off the chip, and initial implementations have found that there's a bit of a trade-off: it takes more power to pump the water through these channels than you extract from the processor. That power isn't used at the site where heat is an issue, so it doesn't get in the way of the heat dissipation, but it does cut into the energy efficiency of the system. The new research builds upon these ideas to boost the efficiency of on-chip cooling systems. And the researchers involved demonstrate that it works using a power-converting chip that otherwise would see the performance reduced by the heat. The research has been published in the journal Nature.

I bought two Biden/Harris lawn signs on Zazzle for about $50 including shipping. They let you share your cart, nice feature. Wish the price were a lot lower though. I want to see Biden signs everywhere.

It can be hard to tear yourself away from the never-ending stream of content provided by the internet, so Vivaldi decided to make taking a break easier by introducing a pause button. PCMag reports: Version 3.3 of the Vivaldi browser introduces a new feature called "Break Mode." Rather than having to close your browser, Break Mode allows you to effectively pause your access to the internet with a button press. Once installed, Vivaldi 3.3 displays a pause button on the status bar. When pressed, Break Mode is engaged, which "mutes and stops HTML5 audio and videos, hides all tabs, panels, and other content leaving the screen clean." It's also possible to trigger Break Mode with the keyboard shortcut Ctrl + "." and to activate it via the browser's Quick Commands. The Vivaldi team sees it as a way of allowing you to "interact with the physical world" while at the same time not having to remember which tabs you had open or what you were viewing when you're ready to return. Pressing the pause button again resumes access just as you left it. Break Mode also acts as a very simple and quick way to hide what you were doing on the internet, which could come in very handy seeing as we're spending so much more time at home together. Other new features include more options for customizing themes as well as adding a new "Private" theme, highlighting base domains to help identify malicious web pages, easier cropping of URLs in the address bar making it easier to visit different parts of a website, and enhancements to the built-in tracker and ad blocker allowing whole pages to be easily blocked.

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

I'm wondering what's new in Glitch since I last took a look, back in April, over four days.

An anonymous reader quotes a report from The Drive: According to several owners of the all-new Model Y, Tesla has allegedly assembled their cars using what appears to be faux wood trim from a home improvement store. It all started with a forum post featuring a photo of a Model Y's frunk plastics removed. The original poster of the thread had reportedly spent more than ten hours disassembling their Model Y to correct poor panel fitment when they came across a large chunk of metal secured with green tape and a small strap. "Someone made a run to Home Depot to make Q2 numbers," jested the thread's original poster. Shortly after, a few other posters chimed in with photos of the same part, showing more wood grain and a few plain white mounts as well. That part you're looking at is the Model Y's Liquid Cooled Condenser (LCC). Its job is essentially that of a heat exchanger, passing refrigerant through a large block where it transfers the thermal properties of the cryogen with other parts of the cooling system. This is just one small sliver of Tesla's unique octavalve cooling system found in the Model Y that is responsible for conditioning the car's cabin, battery, and drive unit simultaneously. The trim appears to be providing some strain relief for the strap holding the LCC in place, perhaps to keep the tension from providing unnecessary stress on the condenser during vibration or flexing, or to prevent any sharp corners from severing the strap itself. However, it's worth noting that Tesla didn't always use what appears to be akin to in-home molding in this application. In fact, several videos on YouTube show vehicles fitted with a clear plastic part in place of the trim. Interestingly, Tesla's own parts catalog doesn't show the any such mounting solution found on the various Model Ys in the thread. It's not clear if the part simply isn't documented, or if it was a rapid fix that has remained in production for quite some time.

Apple has developed two types of masks that the company is beginning to distribute to corporate and retail employees to limit the spread of Covid-19. From a report: The masks -- called the Apple Face Mask and Apple ClearMask -- are the first developed in-house by the Cupertino, California-technology giant for its staff. The company previously created a different face shield for medical workers and distributed millions of other masks across the health-care sector. Apple told staff members that the masks were developed by the Engineering and Industrial Design teams, the same groups that work on devices such as the iPhone and iPad. The Apple Face Mask is made up of three layers to filter incoming and outgoing particles. It can be washed and reused as many as five times, the company told employees. In typical Apple style, the mask looks unique with large coverings on the top and bottom for the wearer's nose and chin. It also has adjustable strings to fit around a person's ears. Apple told staff that the masks were designed and manufactured completely by Apple. The company, which confirmed the news, said it conducted careful research and testing to find the right materials to filter the air properly while not disrupting the supply of medical personal protective equipment.

A European Union privacy regulator has sent Facebook a preliminary order to suspend data transfers to the U.S. about its EU users, WSJ reported Wednesday, citing people familiar with the matter, an operational and legal challenge for the company that could set a precedent for other tech giants. From the report: The preliminary order, the people said, was sent by Ireland's Data Protection Commission to Facebook late last month, asking for the company's response. It is the first significant step EU regulators have taken to enforce a July ruling about data transfers from the bloc's top court. That ruling restricted how companies like Facebook can send personal information about Europeans to U.S. soil, because it found that Europeans have no effective way to challenge American government surveillance. To comply with Ireland's preliminary order, Facebook would likely have to re-engineer its service to silo off most data it collects from European users, or stop serving them entirely, at least temporarily. If it fails to comply with an order, Ireland's data commission has the power to fine Facebook up to 4% of its annual revenue, or $2.8 billion. Nick Clegg, Facebook's top policy and communications executive, confirmed that Ireland's privacy regulator has suggested, as part of an inquiry, that Facebook can no longer in practice conduct EU-U.S. data transfers using a widely used type of contract. "A lack of safe, secure and legal international data transfers would damage the economy and prevent the emergence of data-driven businesses from the EU, just as we seek a recovery from Covid-19," Mr. Clegg said.

Legendary journalist Bob Woodward reports in his new book new details on Russia's election meddling, writing that the NSA and CIA have classified evidence the Russians had placed malware in the election registration systems of at least two Florida counties, St. Lucie and Washington. From a report: While there was no evidence the malware had been activated, Woodward writes, it was sophisticated and could erase voters in specific districts. The voting system vendor used by Florida was also used in states across the country.

Apple's "Sign In with Apple" login system will no longer work with Epic Games accounts as soon as September 11th, Epic said today. The new restriction is another casualty of Apple and Epic's ongoing spat. From a report: If you currently use "Sign In with Apple" for your Epic account, Epic says you'll need to update your account with new login credentials before September 11th to retain access. Epic has put together a guide on how to make that update if you need to do so. Epic also says that it may be able to recover your account manually after the "Sign in with Apple" option goes away, but you'll have to contact the studio directly. Apple requires developers to use its single sign-on system if they offer any other third-party options and want their apps in the App Store -- presumably a driving factor behind Epic offering the service as a sign-in factor in the first place.

I'm guessing the smoke is choking people who live in rural parts of Oregon, California and Washington State, who say they have nothing in common with people who live in LA, SF, Portland and Seattle. Just want to point out they all breathe the same air.

Eighty-four online-only, open-access (OA) journals in the sciences, and nearly 100 more in the social sciences and humanities, have disappeared from the internet over the past 2 decades as publishers stopped maintaining them, potentially depriving scholars of useful research findings, a study has found. From a report: An additional 900 journals published only online also may be at risk of vanishing because they are inactive, says a preprint posted on 3 September on the arXiv server. The number of OA journals tripled from 2009 to 2019, and on average the vanished titles operated for nearly 10 years before going dark, which "might imply that a large number ... is yet to vanish," the authors write. The study didn't identify examples of prominent journals or articles that were lost, nor collect data on the journals' impact factors and citation rates to the articles. About half of the journals were published by research institutions or scholarly societies; none of the societies are large players in the natural sciences. None of the now-dark journals was produced by a large commercial publisher.
