Fast Company's tech editor Harry McCracken (also harrymccSlashdot reader #1,641,347) writes: As part of Fast Company's "1995 week", I wrote about IBM's ThinkPad 701, the famous model with an expanding "butterfly" keyboard [which could be stretched from 9.7-inches to 11.5 inches]. By putting full-sized keys in a subnotebook-sized laptop, it solved one of mobile computing's biggest problems. IBM discontinued it before the end of the year, and neither it nor anyone else ever made anything similar again. And yet it remains amazing. Check out this 1995 ad for the keyboard! The article calls the butterfly ThinkPad "one of the best things the technology industry has ever done with moving parts," and revisits 1995's race "to design a subnotebook-sized laptop with a desktop-sized keyboard." It's still comically thick, standing almost as tall as four MacBook Airs stacked on each other. That height is required to accommodate multiple technologies later rendered obsolete by technological progress, such as a dial-up fax/modem, an infrared port, two PCMCIA expansion card slots, and a bulky connector for an external docking station... Lifting the screen set off a system of concealed gears and levers that propelled the two sections of keyboard into position with balletic grace... A Businesweek article cited sales of 215,000 units and said it was 1995's best-selling PC laptop. Yet by the time that story appeared in February 1996, the 701 had been discontinued. IBM never made anything like it again. Neither did anyone else... As portable computers became more popular, progress in display technology had made it possible for PC makers to use larger screens. Manufacturers were also getting better at fitting a laptop's necessary components into less space. These advances let them design a new generation of thin, light laptops that went beyond the limitations of subnotebooks. Once IBM could make a lightweight laptop with a wider screen, "the need for an expanding keyboard was no longer essential," says [butterfly ThinkPad engineer] George Karidis. "It would have just been a novelty." The article notes a fan's open source guides for repairing butterfly Thinkpads at Project Butterfly, and all the fan-community videos about it on YouTube, "from an excellent documentary to people simply being entranced by it. "As a thing of wonder, it continues to transcend its own obsolescence."

Feature work on Plasma 6.5 this week includes "a major visual change that has been years in the wanting," according to the KDE blog: "rounded bottom corners for windows!" Neowin reports: This visual refresh, planned for the upcoming Plasma 6.5, is a feature that many users have been asking for over a long period, with a formal proposal even being submitted back in 2021. Its official arrival will mean less need for community-developed workarounds like kde-rounded-corners, a popular third-party script that has served this purpose for years. The feature will be enabled by default, but it includes an option for those who prefer the classic, sharp-cornered look.

Twitter co-founder/Block CEO Jack Dorsey isn't just vibe coding new apps like Bitchat and Sun Day. He's also "invested $10 million in an effort to fund experimental open source projects and other tools that could ultimately transform the social media landscape," reports TechCrunch," funding the projects through an online collective formed in May called "andOtherStuff: [T]he team at "andOtherStuff" is determined not to build a company but is instead operating like a "community of hackers," explains Evan Henshaw-Plath [who handles UX/onboarding and was also Twitter's first employee]. Together, they're working to create technologies that could include new consumer social apps as well as various experiments, like developer tools or libraries, that would allow others to build apps for themselves. For instance, the team is behind an app called Shakespeare, which is like the app-building platform Lovable, but specifically for building Nostr-based social apps with AI assistance. The group is also behind heynow, a voice note app built on Nostr; Cashu wallet; private messenger White Noise; and the Nostr-based social community +chorus, in addition to the apps Dorsey has already released. Developments in AI-based coding have made this type of experimentation possible, Henshaw-Plath points out, in the same way that technologies like Ruby on Rails, Django, and JSON helped to fuel an earlier version of the web, dubbed Web 2.0. Related to these efforts, Henshaw-Plath sat down with Dorsey for the debut episode of his new podcast, revolution.social with @rabble... Dorsey believes Bluesky faces the same challenges as traditional social media because of its structure — it's funded by VCs, like other startups. Already, it has had to bow to government requests and faced moderation challenges, he points out. "I think [Bluesky CEO] Jay [Graber] is great. I think the team is great," Dorsey told Henshaw-Plath, "but the structure is what I disagree with ... I want to push the energy in a different direction, which is more like Bitcoin, which is completely open and not owned by anyone from a protocol layer...." Dorsey's initial investment has gotten the new nonprofit up and running, and he worked on some of its initial iOS apps. Meanwhile, others are contributing their time to build Android versions, developer tools, and different social media experiments. More is still in the works, says Henshaw-Plath. "There are things that we're not ready to talk about yet that'll be very exciting," he teases.

"Eight healthy babies were born in Britain," reports Phys.org, "with the help of an experimental technique that uses DNA from three people to help mothers avoid passing devastating rare diseases to their children, researchers reported Wednesday." Mutations in mitochondrial DNA "can cause a range of diseases in children that can lead to muscle weakness, seizures, developmental delays, major organ failure and death," and in rare cases even pre-IVF testing can't clearly detect their presence. Researchers have been developing a technique that tries to avoid the problem by using the healthy mitochondria from a donor egg. They reported in 2023 that the first babies had been born using this method... Using this method means the embryo has DNA from three people — from the mother's egg, the father's sperm and the donor's mitochondria — and it required a 2016 U.K. law change to approve it. It is also allowed in Australia but not in many other countries, including the U.S. Experts at Britain's Newcastle University and Monash University in Australia reported in the New England Journal of Medicine Wednesday that they performed the new technique in fertilized embryos from 22 patients, which resulted in eight babies that appear to be free of mitochondrial diseases. One woman is still pregnant... Robin Lovell-Badge [a stem cell and developmental genetics scientist at the Francis Crick Institute who was not involved in the research] said the amount of DNA from the donor is insignificant, noting that any resulting child would have no traits from the woman who donated the healthy mitochondria... In the U.K., every couple seeking a baby born through donated mitochondria must be approved by the country's fertility regulator. As of this month, 35 patients have been authorized to undergo the technique. Critics have previously raised concerns, warning that it's impossible to know the impact these sorts of novel techniques might have on future generations... But in countries where the technique is allowed, advocates say it could provide a promising alternative for some families.

"I vibe coded a little game called Coldplay Canoodlers," reads the X.com post by gaming enthusiast/songwriter Jonathan Mann. "You're the camera operator and you have to find the CEO and HR lady canoodling. 10 points every time you find them." Mann's post includes a 30-second clip from the game, which is playable here. Forbes notes that the TikTok video of the couple's reaction has drawn more than 100 million views — and that the married-to-someone-else CEO has now tendered his resignation from his dataops company Astronomer (which was accepted). The company is now searching for a new chief executive, according to a statement posted on LinkedIn. ("Comments have been turned off on this post...") "Our leaders are expected to set the standard in both conduct and accountability, and recently, that standard was not met." But songwriter Mann saw a chance to have some fun, writes Forbes: Mann used ChatGPT to make the "Coldplay Canoodlers" game, inputting such prompts as: "Can you generate an 8-bit pixel image of a stadium concert viewed from the stage" and "there should be a large jumbotron somewhere up in the stadium seats." He also entered rough drawings of the visual style he envisioned... The response to the game, Mann said in an interview, has been unexpected. "I have gone viral many times with my songs," he said. It's "very strange to have it happen with a game I made in four hours." Songwriter Mann has been sharing an original song online every day for over 17 years. Last summer Slashdot also covered Mann's attempts to sell NFTs of his songs, and his concerns about SEC regulations. (This led him to file a real-world legal challenge — and to write a song titled "I'm Suing the SEC".) So with all the attention this weekend to his instant game, there was nothing to do but... write a new song about it. And minutes ago on X.com, Mann also posted a new update about his game. "I turned it into an NFT." "Took some time," Mann explained later. "But I vibe coded my own ERC-721 contract and minted the game as a playable NFT. (Plays great on OpenSea)."

It's "a milestone for scalable quantum technologies," according to the announcement from Boston University. Scientists from Boston University, UC Berkeley, and Northwestern University "reported the world's first electronic-photonic-quantum system on a chip, according to a study published in Nature Electronics." Quantum computing is on "a decades-long path from concept to reality," says Milos PopoviÄ, associate professor of electrical and computer engineering at BU and a senior author on the study. "This is a small step on that path — but an important one, because it shows we can build repeatable, controllable quantum systems in commercial semiconductor foundries." The system combines quantum light sources and stabilizing electronics using a standard 45-nanometer semiconductor manufacturing process to produce reliable streams of correlated photon pairs (particles of light) — a key resource for emerging quantum technologies. The advance paves the way for mass-producible "quantum light factory" chips and large-scale quantum systems built from many such chips working together... Just as electronic chips are powered by electric currents, and optical communication links by laser light, future quantum technologies will require a steady stream of quantum light resource units to perform their functions. To provide this, the researchers' work created an array of "quantum light factories" on a silicon chip, each less than a millimeter by a millimeter in dimension... "What excites me most is that we embedded the control directly on-chip — stabilizing a quantum process in real time," says Anirudh Ramesh, a PhD student at Northwestern who led the quantum measurements. "That's a critical step toward scalable quantum systems." Thanks to long-time Slashdot reader fahrbot-bot for sharing the news.

"Nearly 2 million people protected their privacy by deleting their DNA from 23andMe after it declared bankruptcy in March," writes a Washington Post technology columnist. "Now it's back with the same person in charge — and I still don't trust it." As of this week, genetic data from the more than 10 million remaining 23andMe customers has been formally sold to an organization called TTAM Research Institute for $305 million. That nonprofit is run by the person who co-founded and ran 23andMe, Anne Wojcicki. In a recent email to customers, the new 23andMe said it "will be operating with the same employees and privacy protocols that have protected your data." Never mind that Wojcicki and her privacy protocols are what put your DNA at risk in the first place... The company is legally obligated to maintain and honor 23andMe's existing privacy policies, user consents and data protection measures. And as part of a settlement with states, TTAM also agreed to provide annual privacy reports to state regulators and set up a privacy board. But it hasn't agreed to take the fundamental step of asking for permission to acquire existing customers' genetic information. And it's leaving the door open to selling people's genes to the highest bidder again in the future... Existing 23andMe customers have the right to delete their data or opt out of TTAM's research. But the new company is not asking for opt-in permission before it takes ownership of customers' DNA... Why does that matter? Because people who handed over the DNA 15 years ago, often to learn about their genetic ancestry, never imagined it might be used in this way now. Asking for new permission might significantly shrink the size (and value) of 23andMe's DNA database — but it would be the right thing to do given the rocky history. Neil M. Richards [the Washington University professor who served as privacy ombudsman for the bankruptcy court], pointed out that about a third of 23andMe customers haven't logged in for at least three years, so they may have no idea what is going on. Some 23andMe users never even clicked "agree" on a legal agreement that allowed their data to be sold like this; the word "bankruptcy" wasn't added to the company's privacy policy until 2022. And then there is an unknown number of deceased users who most certainly can't consent, but whose DNA still has an impact on their living genetic relatives... [S]everal states have argued that their existing genetic privacy laws don't allow 23andMe to receive the information without getting permission from every single person. Virginia has an ongoing lawsuit over the issue, and the California attorney general's office told me it "will continue to fight to protect and vindicate the rights" of consumers.... Two more points of concern: "There is nothing in 23andMe's bankruptcy agreement or privacy statement to prevent TTAM from selling or transferring DNA to some other organization in the future." The article also notes a 2023 data breach affecting 6.9 million users, arguing "They haven't shown they can keep your data safe... 23andMe's financial struggles could make it hard to run a robust cybersecurity program."

An anonymous reader shared this report from the Washington Post: Ships trigger seafloor methane emissions while moving through shallow water, researchers report in Communications Earth & Environment. The scientists say the unexpected discovery has nothing to do with the type of fuel used by the ship. Instead, "ship-induced pressure changes and turbulent mixing" trigger the release of the gas from the seafloor. Bubbles and gas diffusion push the methane into the atmosphere, where it acts as a greenhouse gas... Container and cruise ships triggered the largest and most frequent methane emissions, but the study suggests that ships of all kinds, regardless of their type of engine or size, trigger methane emissions. Researchers said they observed emissions that were 20 times higher in the shipping lane than in undisturbed nearby areas. Given the number of ports in similarly shallow areas worldwide, it's important to learn more about emissions in shipping lanes and to better estimate their "hitherto unknown impact," study co-author Johan Mellqvist, a professor of optical remote sensing at Chalmers University of Technology in Sweden, said in a news release.
