Derek Lowe, a medicinal chemist and freelance writer on science and pharmaceutical topics, comments on the latest developments around last week's remarkable claim of a well-above-room-temperature superconducting material at ambient pressure, dubbed LK-99. Here's an excerpt from his post: As of this morning, there are (as yet not really verified) reports of replication from the Huazhong University of Science and Technology in China. At least, a video has been posted showed what could be a sample of LK-99 levitating over a magnet due to the Meissner effect, and in different orientations relative to the magnet itself. That's important, because a (merely!) paramagnetic material can levitate in a sufficiently strong field (as can diamagnetic materials like water droplets and frogs), but these can come back to a particular orientation like a compass needle. Superconductors are "perfect diamagnets," excluding all magnetic fields, and that's a big difference. The "Meissner effect" that everyone has been hearing about so much is observed when a material first becomes superconductive at the right temperature and expels whatever magnetic fields were penetrating it at the time. All this said, we're having to take the video on the statements of whoever made/released it, and there are other possible explanations for the it that do not involve room-temperature superconductivity. I will be very happy if this is a real replication, but I'm not taking the day off yet to celebrate just based on this.

And even though I'm usually more of an experimental-results guy than a theory guy, two other new preprints interest me greatly. One is from a team (PDF) at the Shenyang National Laboratory for Materials Science, and the other (PDF) is from Sinead Griffin at Lawrence Berkeley. Both start from the reported X-ray structural data of LK-99 and look at its predicted behavior via density functional theory (DFT) calculations. And they come to very similar conclusions: it could work. This is quite important, because this could mean that we don't need to postulate completely new physics to explain something like LK-99 - if you'd given the starting data to someone as a blind test, they would have come back after the DFT runs saying "You know, this looks like it could be a really good superconductor..." [...]

I am guardedly optimistic at this point. The Shenyang and Lawrence Berkeley calculations are very positive developments, and take this well out of the cold-fusion "we can offer no explanation" territory. Not that there's anything wrong with new physics (!), but it sets a much, much higher bar if you have to invoke something in that range. I await more replication data, and with more than just social media videos backing them up. This is by far the most believable shot at room-temperature-and-pressure superconductivity the world has seen so far, and the coming days and weeks are going to be extremely damned interesting.

Google is experimenting with the use of AI to auto-generate YouTube video summaries, according to a notice on a support page dated July 31st. From a report: The page, which we spotted via Android Police, notes that these summaries will only appear next to a limited number of English-language videos, and will only be viewable by a limited number of users. They'll appear on YouTube's watch and search pages, and are intended to give a brief overview of a video's contents without replacing its existing description written by a human. "We're starting to test AI auto-generated summaries on YouTube, so that it's easier for you to read a quick summary about a video and decide whether it's the right fit for you," the support page reads.

Meta intends to ask users in the European Union for their consent before allowing businesses to target advertising based on what they view on its services such as Facebook and Instagram, the social media giant said on Tuesday. From a report: Meta said the change is to address a number of evolving regulatory requirements in the region and stems from an order in January by Ireland's Data Protection Commissioner, Meta's lead EU regulator, to reassess the legal basis on how it targets ads.

Facebook and Instagram users had effectively agreed to allow their data to be used in targeted advertising when they signed up to the services' terms and conditions, until the regulator ruled it could not process personal information in that way. "Today, we are announcing our intention to change the legal basis that we use to process certain data for behavioural advertising for people in the EU, EEA (European Economic Area) and Switzerland from 'Legitimate Interests' to 'Consent'," Meta said in a blog post.

An anonymous reader quotes a report from Axios: Google plans to overhaul its Assistant to focus on using generative AI technologies similar to those that power ChatGPT and its own Bard chatbot, according to an internal e-mail sent to employees Monday and seen by Axios. Google says some work on the revamped Assistant has begun, starting with the mobile version of the product. As part of the move, Google is reorganizing the teams that work on Assistant. The company said in the email it's making a small number of layoffs in conjunction with the shift. The move will involve eliminating dozens of jobs, Axios is told, out of the thousands of employees who work on the Assistant "We remain deeply committed to Assistant and we are optimistic about its bright future ahead," Google VP Peeyush Ranjan and director of product Duke Dukellis wrote in the e-mail.

An anonymous reader quotes a report from Ars Technica: Starting today, Facebook users may feel a little less safe posting anonymously. The Court of the Hague in The Netherlands ruled that Meta Ireland must unmask an anonymous user accused of defaming the claimant, a male Facebook user who allegedly manipulated and made secret recordings of women he dated. The anonymous Facebook user posted the allegedly defamatory statements in at least two private Facebook groups dedicated to discussing dating experiences. The claimant could not gain access but was shown screenshots from the groups, one with about 2,600 members and one with around 61,000 members. The claimant argued that his reputation had suffered from the repeated postings that included photos of the man and alleged screenshots of his texts.

The claimant tried to get Meta to remove the posts, but Meta responded with an email saying that it would not do so because "it is not clear to us that the content you reported is unlawful as defamation." At that point, Meta suggested that the man contact the anonymous user directly to resolve the matter, triggering the lawsuit against Meta. Initially, the claimant asked the court to order Meta to delete the posts, identify the anonymous user, and flag any posts in other private Facebook groups that could defame the claimant. While arguing the case, Meta had defended the anonymous user's right to freedom of expression, but the court decided that the claimant -- whose name is redacted in court documents -- deserved an opportunity to challenge the allegedly defamatory statements. Partly for that reason, the court ordered Meta to provide "basic subscriber information" on the anonymous user, including their username, as well as any names, email addresses, or phone numbers associated with their Facebook account. The court did not order Meta to remove the posts or flag any others that may have been shared in private groups, though.

Meta has already agreed to comply with the order, the court's ruling said. However, if Meta fails to provide the Facebook user's identifying information, the social media company risks a penalty of approximately $1,200 daily. The maximum fine that Meta could face is less than $130,000. [...] Meta's defense of the anonymous user's right to free speech failed, the court said, because freedom of speech is not unlimited. "Someone who, without evidence, repeatedly makes serious and clearly traceable accusations, must take into account, partly in the light of the conditions applied by Facebook, that he or she may be confronted with a measure whereby his or her anonymity is lifted," the court order said. Although the key concern for The Court in the Hague appeared to be that the statements posted anonymously were plausibly defamatory, the order also noted that the content would not have to necessarily be unlawful for Facebook to be ordered to identify the user posting it. "According to settled case law, under certain circumstances Meta has an obligation to provide identifying data, even if the content of the relevant messages is not unmistakably unlawful," the court order said.

tedlistens writes: All large language models are liable to produce toxic and other unwanted outputs, either by themselves or at the encouragement of users. To evaluate and "detoxify" their LLMs, OpenAI, Meta, Anthropic, and others are using Perspective API -- a free tool from Google's Jigsaw unit designed to flag toxic human speech on social media platforms and comment sections. But, as Alex Pasternack reports at Fast Company, researchers and Jigsaw itself acknowledge problems with Perspective and other AI classifiers, and worry that AI developers using them to build LLMs could be inheriting their failures, false positives, and biases. That could, in turn, make the language models more biased or less knowledgeable about minority groups, harming some of the same people the classifiers are meant to help. "Our goal is really around humans talking to humans," says Jigsaw's Lucy Vasserman, "so [using Perspective to police AI] is something we kind of have to be a little bit careful about." "Think of all the problems social media is causing today, especially for political polarization, social fragmentation, disinformation, and mental health," Eric Schmidt wrote in a recent essay with Jonathan Haidt about the coming harms of generative AI. "Now imagine that within the next 18 months -- in time for the next presidential election -- some malevolent deity is going to crank up the dials on all of those effects, and then just keep cranking."

While Jigsaw says the unit is focused on tackling toxicity and hate, misinformation, violent extremism, and repressive censorship, a former Jigsaw employee says they're concerned that Perspective could only be a stopgap measure for AI safety. "I'm concerned that the safeguards for models are becoming just lip service -- that what's being done is only for the positive publicity that can be generated, rather than trying to make meaningful safeguards," the ex-employee says.

In closing, the article leaves us with a quote from Vasserman. She says: "I think we are slowly but surely generally coming to a consensus around, these are the different types of problems that you want to be thinking about, and here are some techniques. But I think we're still -- and we'll always be -- far from having it fully solved."

Long-time Slashdot reader nairnr shares a report from The Register: Cloud giant AWS will start charging customers for public IPv4 addresses from next year, claiming it is forced to do this because of the increasing scarcity of these and to encourage the use of IPv6 instead. It is now four years since we officially ran out of IPv4 ranges to allocate, and since then, those wanting a new public IPv4 address have had to rely on address ranges being recovered, either from from organizations that close down or those that return addresses they no longer require as they migrate to IPv6.

If Amazon's cloud division is to be believed, the difficulty in obtaining public IPv4 addresses has seen the cost of acquiring a single address rise by more than 300 percent over the past five years, and as we all know, the business is a little short of cash at the moment, so is having to pass these costs on to users. "This change reflects our own costs and is also intended to encourage you to be a bit more frugal with your use of public IPv4 addresses and to think about accelerating your adoption of IPv6 as a modernization and conservation measure,' writes AWS Chief Evangelist Jeff Barr, on the company news blog.

The update will come into effect on February 1, 2024, when AWS customers will see a charge of $0.005 (half a cent) per IP address per hour for all public IPv4 addresses. These charges will apparently apply whether the address is attached to a service or not, and like many AWS charges, appear inconsequential at first glance but can mount up over time if a customer is using many of them. These charges will apply to all AWS services including EC2, Relational Database Service (RDS) database instances, Elastic Kubernetes Service (EKS) nodes, and will apply across all AWS regions, the company said. However, customers will not be charged for IP addresses that they own and bring to AWS using Amazon's BYOIP feature. AWS offers a free tier for EC2, and this will include 750 hours of public IPv4 address usage per month for the first 12 months, starting from the same date the charges do.

An anonymous reader quotes a report from TIME: U.S. and European officials are growing increasingly concerned about China's accelerated push into the production of older-generation semiconductors and are debating new strategies to contain the country's expansion. President Joe Biden implemented broad controls over China's ability to secure the kind of advanced chips that power artificial-intelligence models and military applications. But Beijing responded by pouring billions into factories for the so-called legacy chips that haven't been banned. Such chips are still essential throughout the global economy, critical components for everything from smartphones and electric vehicles to military hardware. That's sparked fresh fears about China's potential influence and triggered talks of further reining in the Asian nation, according to people familiar with the matter, who asked not to be identified because the deliberations are private. The U.S. is determined to prevent chips from becoming a point of leverage for China, the people said.

Commerce Secretary Gina Raimondo alluded to the problem during a panel discussion last week at the American Enterprise Institute. "The amount of money that China is pouring into subsidizing what will be an excess capacity of mature chips and legacy chips -- that's a problem that we need to be thinking about and working with our allies to get ahead of," she said. While there's no timeline for action to be taken and information is still being gathered, all options are on the table, according to a senior Biden administration official. The most advanced semiconductors are those produced using the thinnest etching technology, with 3-nanometers state of the art today. Legacy chips are typically considered those made with 28-nm equipment or above, technology introduced more than a decade ago.

Senior E.U. and U.S. officials are concerned about Beijing's drive to dominate this market for both economic and security reasons, the people said. They worry Chinese companies could dump their legacy chips on global markets in the future, driving foreign rivals out of business like in the solar industry, they said. Western companies may then become dependent on China for these semiconductors, the people said. Buying such critical tech components from China may create national security risks, especially if the silicon is needed in defense equipment. "The United States and its partners should be on guard to mitigate nonmarket behavior by China's emerging semiconductor firms," researchers Robert Daly and Matthew Turpin wrote in a recent essay for the Hoover Institution think tank at Stanford University. "Over time, it could create new U.S. or partner dependencies on China-based supply chains that do not exist today, impinging on U.S. strategic autonomy."

According to Windows Central, Lenovo is working on a handheld gaming PC dubbed "Legion Go," featuring Windows 11 and Ryzen chips. From the report: While details are scant right now, we understand this will sport AMD's new Phoenix processors, which the chip firm describes as ultra-thin, focused on gaming, AI, and graphics for ultrabooks. The fact the Legion Go will sport Ryzen chips pretty much guarantees that this is a Windows PC gaming handheld, as part of Lenovo's popular gaming "Legion" brand. As of writing, there's no information on exactly when this device could become available, or if, indeed, it'll become available at all.

According to our information, the Legion Go could sport an 8-inch screen, making it larger than the ASUS ROG Ally or the Steam Deck, both of which have a 7-inch display. PC and console games ported to PC are often designed for larger monitors or even TVs, and on smaller screens, UI elements can be difficult to see, especially if the game doesn't have a UI scaling option. A larger display could give the Legion Go a decent advantage over its competitors if it remains lightweight and balanced, which of course remains to be seen. The AMD Phoenix 7040 series chips are described by the firm as "ultra-thin" for powerful, but elegant ultrabook-style devices. They should lend themselves well to a device like the Legion Go, supporting 15W low-power states for lightweight games and maximized battery life, similar to the Steam Deck and ROG Ally. The Z1 Extreme in the ASUS ROG Ally can perform with a TDP below 15W, however, which could give the ROG Ally some advantages there. There's every chance the Legion Go could have other configurations we're unaware of yet, though, we'll just have to wait and see.

Apple's Screen Time controls are failing parents. From a report: The company's cloud-based Family Sharing system is designed in part for parents to remotely schedule off-limits time and restrict apps and adult content on their children's iPhones, iPads and iPod Touch models. Trouble is, parents are finding that when they use their iPhones to set restrictions on their kids' devices, the changes don't stick. "We are aware that some users may be experiencing an issue where Screen Time settings are unexpectedly reset," an Apple spokeswoman said. "We take these reports very seriously and we have been, and will continue, making updates to improve the situation."

Downtime, found in Settings under Screen Time, is the tool parents use to define the hours each day that a kid's device is limited or completely unusable. But when they check the setting lately, they often see the times they scheduled have reverted to a previous setting, or they see no restrictions at all. This can go unnoticed for days or weeks -- and kids don't always report back when they get extra time for games and social media. Apple previously acknowledged the bug, calling it "an issue where Screen Time settings may reset or not sync across all devices." However, the company had reported the issue fixed with iOS 16.5, which came out in May. In our testing the bug persists, even with the new public beta of iOS 17.

Managing windows — "even after 50 years, nobody's fully cracked it yet," writes GNOME developer Tobias Bernard: Most of the time you don't care about exact window sizes and positions and just want to see the windows that you need for your current task. Often that's just a single, maximized window. Sometimes it's two or three windows next to each other. It's incredibly rare that you need a dozen different overlapping windows. Yet this is what you end up with by default today, when you simply use the computer, opening apps as you need them. Messy is the default, and it's up to you to clean it up...

We've wanted more powerful tiling for years, but there has not been much progress due to the huge amount of work involved on the technical side and the lack of a clear design direction we were happy with. We now finally feel like the design is at a stage where we can take concrete next steps towards making it happen, which is very exciting! The key point we keep coming back to with this work is that, if we do add a new kind of window management to GNOME, it needs to be good enough to be the default. We don't want to add yet another manual opt-in tool that doesn't solve the problems the majority of people face.
The current concept imagines three possible layout states for windows:

- Floating, the classic stacked windows model
- Edge Tiling, i.e. windows splitting the screen edge-to-edge
- Mosaic, a new window management mode which combines the best parts of tiling and floating

Mosaic is the default — where "you open a window, it opens centered on the screen at a size that makes the most sense for the app." (Videos in the blog post show how this works.) "As you open more windows, the existing windows move aside to make room for the new ones. If a new window doesn't fit (e.g. because it wants to be maximized) it moves to its own workspace. If the window layout comes close to filling the screen, the windows are automatically tiled." You can also manually tile windows. If there's enough space, other windows are left in a mosaic layout. However, if there's not enough space for this mosaic layout, you're prompted to pick another window to tile alongside. You're not limited to tiling just two windows side by side. Any tile (or the remaining space) can be split by dragging another window over it, and freely resized as the window minimum sizes allow.
So what's next? Windows can already set a fixed size and they have an implicit minimum size, but to build a great tiling experience we need more... At the Brno hackfest in April we had an initial discussion with GNOME Shell developers about many of the technical details. There is tentative agreement that we want to move in the direction outlined in this post, but there's still a lot of work ahead... We'd like to do user research to validate some of our assumptions on different aspects of this, but it's the kind of project that's very difficult to test outside of an actual prototype that's usable day to day.
"There's another issue with GNOME's current windowing system," notes 9to5Linux. "If the stacking is interrupted, newly opened windows will be opened from the top, covering the first opened window." For this new windowing system to become a reality, the GNOME devs would have to do a lot of user research and test numerous scenarios so that everyone can be happy. As you can imagine, this could take months or even years, so if you want to get involved and help them do it faster, please reach out to the GNOME team here.

An anonymous reader shared this story from CNN: Barry Sherry was traveling from his home in Virginia to Europe for the cycling trip of a lifetime: a week riding through the Swiss Alps, followed by another in Luxembourg, where his cycling group was riding with two former Tour de France competitors, and then a third week cycling in Finland with friends. It was, he says, to be his last cycling trip to Europe. "I'm 68 — I'm getting old," he says... While his suitcase arrived on the carousel, his [$8,000] bike — zipped up in its carrier — had become one of the 7.6 out of every 1,000 items of luggage to be, as the industry coyly terms it, "mishandled." In other words: lost...

The "Find My" app, which traces Apple devices including AirTags, showed the bike at Heathrow... British Airways has up to six flights per day from Heathrow to Zurich, but as each day came and went, none of them had Sherry's bike on board... Each day, he updated his location on the British Airways website, and each day, his bike failed to arrive — or move from Heathrow, according to the AirTag. By this point Sherry was tweeting the airline daily, showing them screenshots of the mapped location of the bike, but getting generic responses from British Airways that he believes were bots... That evening, he tweeted the location of the bag again, tagging American Airlines (who'd sold him the ticket) and Heathrow Airport, too. "AA seemed to have a human at the other end, and I thought maybe they could reach a human at BA," he says.

Was it that final tweet, tagging AA and Heathrow, that did it? Sherry will never know — though he suspects the daily tweets showing screenshots of the bike's location were the key. After his tweet on Thursday night to all three accounts, on Friday morning he checked his Find My app, and saw his bike was on the move... "Had I not started an annoying Twitter campaign, I do think it would have remained at Heathrow until I could have talked to someone face to face."
CNN reports that Sherry's week in Luxembourg "went ahead as planned, with Sherry adding that he was particuarly attached to his bike because "Fourteen years ago I was diagnosed with cancer, and the only time I wasn't thinking about it was when I was riding my bike."

He'd put the AirTag with his bike "after hearing other cyclists rave about them."

"Over the past week, a Reddit employee has posted to subreddits with ousted mods, asking for new volunteers," reports Ars Technica.

But it's not always going smoothly... A Reddit employee going by ModCodeofConduct (Reddit has refused to disclose the real names of admins representing the company on the platform) has posted to numerous subreddits over recent days, including r/IRLEasterEggs, r/donthelpjustfilm, r/ActLikeYouBelong, r/malefashionadvice, and r/AccidentalRenaissance... Like most official Reddit posts since the API war began, the comments under the job ads display users' discontent.

"May I nominate a mod? I think u/ConspirOC would be a great mod, as he created this subreddit and has successfully run it for years, before you forcibly removed him," a user going by LittleManOnACan wrote on ModCodeofConduct's post seeking replacement r/IRLEasterEggs mods. "Additionally, fire Steve Huffman (Fuck u/Spez)."

There's also a desire among Reddit users for a return to not just how things were but an acknowledgment of the efforts made by many previous moderators, how things changed, and why things are different now. A Redditor going by QuicklyThisWay wrote on ModCodeofConduct's post for news mods for r/IRLEasterEggs:

"Just to be clear for anyone 'applying' to be a moderator. The user that created the subreddit and any other mods were removed by admins for making the community private. Even though the option to change to private is available to all subreddits at any time, the admins have not and will not respect any 'autonomy' moderators appear to have...

As Ars has previously detailed, user protests didn't prevent third-party Reddit apps from closing. However, they have disrupted the platform.

Reddit didn't answer questions Ars sent about its replacement mod criteria or how it'll help ensure new mods can properly handle their newfound volunteer duties...
"mods Ars has spoken with over the weeks have frequently pointed to the potential for burnout, death threats, long training sessions (from other volunteer mods), and rapid turnover for Reddit mods..." the article notes, adding "Without mods proven to be dedicated and experienced, it's unclear how fervently such efforts will continue in the future...

"Disgruntled mods and ex-mods continue seeking new platforms to continue community discussions, including Lemmy and Discord. And as of this writing, there are still 1,900 subreddits private, per the Reddark_247 tracker."

Meanwhile, the third annual edition of Reddit's annual pixel-placing event r/Place "turned into a battleground for dunking on the CEO," reports Polygon. A Reddit spokesperson declined to comment about this year's edition of r/Place, telling Polygon via email "redditors are going to reddit."
Gizmodo's article includes a timelapse video (from YouTube) that they say captures "the whimsy — and anger — of its users," including "plenty of protest art directed at CEO Steve Huffman, who goes by u/spez on the platform..." While there are plenty of examples of "Fuck Spez" to go around, the most creative moment occurred at the end of the project. As r/Place wound to a close, users were able to place a pixel once every thirty seconds, but the pixel had to be white — an effort to wipe the slate clean. However, in the final moments of the project, users collaborated to leave one massive "FUCK SPEZ" across the canvas.

Oxide Computer Company spent four years working toward "The power of the cloud in your data center... bringing hyperscaler agility to the mainstream enterprise." And on June 30, Oxide finally shipped its very first server rack.

Long-time Slashdot reader destinyland shares this report: It's the culmination of years of work — to fulfill a long-standing dream. In December of 2019, Oxide co-founder Jess Frazelle had written a blog post remembering conversations over the year with people who'd been running their own workloads on-premises... "Hyperscalers like Facebook, Google, and Microsoft have what I like to call 'infrastructure privilege' since they long ago decided they could build their own hardware and software to fulfill their needs better than commodity vendors. We are working to bring that same infrastructure privilege to everyone else!"

Frazelle had seen a chance to make an impact with "better integration between the hardware and software stacks, better power distribution, and better density. It's even better for the environment due to the energy consumption wins."
Oxide CTO Bryan Cantrill sees real problems in the proprietary firmware that sits between hardware and system software — so Oxide's server eliminates the BIOS and UEFI altogether, and replaces the hardware-managing baseboard management controller (or BMC) with "a proper service processor." They even wrote their own custom, all-Rust operating system (named Hubris). On the Software Engineering Daily podcast, Cantrill says "These things boot like a rocket."

And it's all open source. "Everything we do is out there for people to see and understand..." Cantrill added. On the Changelog podcast Cantrill assessed its significance. "I don't necessarily view it as a revolution in its own right, so much as it is bringing the open source revolution to firmware."

Oxide's early funders include 92-year-old Pierre Lamond (who hired Andy Grove at Fairchild Semiconductor) — and customers who supported their vision. On Software Engineering Daily's podcast Cantrill points out that "If you're going to use a lot of compute, you actually don't want to rent it — you want to own it."

"A new group of automotive super friends is banding together," reports the Verge, "promising to build the next big North American electric vehicle charging network." These worldwide automakers — BMW, General Motors, Honda, Hyundai, Kia, Mercedes-Benz, and Stellantis — announced a planned joint venture Wednesday to erect easy-to-activate DC fast chargers along US and Canadian highways and in urban environments.

The grand plan for the currently unnamed partnership is to install "at least" 30,000 high-speed EV chargers by 2030, with the first ones to open summer 2024 in the US. The collective plans to leverage National Electric Vehicle Infrastructure (NEVI) funding in the US and will also use other private and public funding from state and federal sources to build out the network... The new stations will connect and charge EV models made by the partnered automakers without having to fumble with another charging station app. The companies also plan to integrate the developing "Plug and Charge" standard that the Federal Highway Administration is attempting to standardize... All stations will include the standardized Tesla North American Charging Standard (NACS) ports and also the current widely used Combined Charging System (CCS) plugs.
"The new joint venture is also planned to be entirely powered by renewable energy," the article adds.

But "It's not known if renewable energy will directly power them or if the companies plan to buy credits like Rivian announced Tuesday."

An anonymous reader quotes a report from Ars Technica: Meta's new Twitter competitor, Threads, is looking for ways to keep users interested after more than half of the people who signed up for the text-based platform stopped actively using the app, Meta CEO Mark Zuckerberg reportedly told employees in a company town hall yesterday. Threads launched on July 5 and signed up over 100 million users in less than five days, buoyed by user frustration with Elon Musk-owned Twitter.

"Obviously, if you have more than 100 million people sign up, ideally it would be awesome if all of them or even half of them stuck around. We're not there yet," Zuckerberg told employees yesterday, according to Reuters, which listened to audio of the event. Third-party data suggests that Threads may have lost many more than half of its active users. Daily active users for Threads on Android dropped from 49 million on July 7 to 23.6 million on July 14, and then to 12.6 million on July 23, web analytics company SimilarWeb reported.

"We don't yet have daily numbers for iOS, but we suspect the boom-and-bust pattern is similar," SimilarWeb wrote. "Threads took off like a rocket, with its close linkage to Instagram as the booster. However, the developers of Threads will need to fill in missing features and add some new and unique ones if they want to make checking the app a daily habit for users." Although losing over half of the initial users in a short period might sound discouraging, the Reuters article said Zuckerberg told employees that user retention was better than Meta executives expected. "Zuckerberg said he considered the drop-off 'normal' and expected retention to grow as the company adds more features to the app, including a desktop version and search functionality," Reuters wrote.

Katie Malone writes via Engadget: "Tor" evokes an image of the dark web; a place to hire hitmen or buy drugs that, at this point, is overrun by feds trying to catch you in the act. The reality, however, is a lot more boring than that -- but it's also more secure. The Onion Router, now called Tor, is a privacy-focused web browser run by a nonprofit group. You can download it for free and use it to shop online or browse social media, just like you would on Chrome or Firefox or Safari, but with additional access to unlisted websites ending in .onion. This is what people think of as the "dark web," because the sites aren't indexed by search engines. But those sites aren't an inherently criminal endeavor.

"This is not a hacker tool," said Pavel Zoneff, director of strategic communications at The Tor Project. "It is a browser just as easy to use as any other browser that people are used to." That's right, despite common misconceptions, Tor can be used for any internet browsing you usually do. The key difference with Tor is that the network hides your IP address and other system information for full anonymity. This may sound familiar, because it's how a lot of people approach VPNs, but the difference is in the details. VPNs are just encrypted tunnels hiding your traffic from one hop to another. The company behind a VPN can still access your information, sell it or pass it along to law enforcement. With Tor, there's no link between you and your traffic, according to Jed Crandall, an associate professor at Arizona State University. Tor is built in the "higher layers" of the network and routes your traffic through separate tunnels, instead of a single encrypted tunnel. While the first tunnel may know some personal information and the last one may know the sites you visited, there is virtually nothing connecting those data points because your IP address and other identifying information are bounced from server to server into obscurity.

Accessing unindexed websites adds extra perks, like secure communication. While a platform like WhatsApp offers encrypted conversations, there could be traces that the conversation happened left on the device if it's ever investigated, according to Crandall. Tor's communication tunnels are secure and much harder to trace that the conversation ever happened. Other use cases may include keeping the identities of sensitive populations like undocumented immigrants anonymous, trying to unionize a workplace without the company shutting it down, victims of domestic violence looking for resources without their abuser finding out or, as Crandall said, wanting to make embarrassing Google searches without related targeted ads following you around forever.

Apple will soon start cracking down on apps that collect data on users' devices in order to track them (aka "fingerprinting"), according to an article on its developer site. Engadget writes: Starting with the release of iOS 17, tvOS 17, watchOS 10 and macOS Sonoma, developers will be required to explain why they're using so-called required reason APIs. Apps failing to provide a valid reason will be rejected started in spring of 2024. "Some APIs... have the potential of being misused to access device signals to try to identify the device or user, also known as fingerprinting. Regardless of whether a user gives your app permission to track, fingerprinting is not allowed," Apple wrote.

"To prevent the misuse of certain APIs that can be used to collect data about users' devices through fingerprinting, you'll need to declare the reasons for using these APIs in your app's privacy manifest." The new rules could increase the rate of app rejections, some developers told 9to5Mac. For instance, an API called UserDefaults falls into the "required reason" category, but since it stores user preferences, it's used by a lot of apps.

A coalition of a half-dozen open-source AI stakeholders -- Hugging Face, GitHub, EleutherAI, Creative Commons, LAION and Open Future -- are calling on EU policymakers to protect open source innovation as they finalize the EU AI Act, which will be the world's first comprehensive AI law. From a report: In a policy paper released this week, "Supporting Open Source and Open Science in the EU AI Act," the open-source AI leaders offered recommendations âoefor how to ensure the AI Act works for open source" -- with the "aim to ensure that open AI development practices are not confronted with obligations that are structurally impractical to comply with or that would be otherwise counterproductive."

According to the paper, "overbroad obligations" that favor closed and proprietary AI development -- like models from top AI companies such as OpenAI, Anthropic and Google -- "threaten to disadvantage the open AI ecosystem." The paper was released as the European Commission, Council and Parliament debate the final EU AI Act in what is known as the "trilogue," which began after the European Parliament passed its version of the bill on June 14. The goal is to finish and pass the AI Act by the end of 2023 before the next European Parliament elections.

Google is changing the Play Store ranking algorithms to increase the visibility of apps that better support large screens. Google detailed the changes in a blog post: "Apps and games that adhere to our large screen app quality guidelines will now be ranked higher in search and Apps and Games Home. This helps users find apps that resize well, aren't letterboxed, and support both portrait and landscape orientations. Editors' Choice and other curated collections and articles will also consider these criteria going forward, creating new featuring opportunities for optimized apps." Ars Technica reports: The large-screen app guidelines have various tiers, but they recommend keyboard, mouse, and stylus support, a two-pane tablet layout, drag-and-drop support, and foldable display awareness. The post also reiterates some improvements that Google has already rolled out, like showing tablet screenshots to tablet users and downranking apps that crash a lot.

The big news is that the search results will switch to a two-pane layout on big screens. The search result list will live on the left-hand side, and tapping on each result will load a details page on the right. Previously, the results page was a stretched-out phone interface, with results on the left and nothing on the right. It would be nice if the top charts got this two-pane design, too, but that hasn't changed yet. Google says these changes are "just the beginning of our journey in creating a tailored Play Store experience for large screens." So hopefully, Google's developers will follow Google's developer guidelines soon.
