Prop and scenic painting technician Carousse shared this really cool carbon microphone on instructables. I worked on a play that required a functioning early 20th century carbon microphone. They are rare, expensive, actors can accidently drop them and would need to be re-wired with a modern wireless microphone. I like this kind of challenge because […]

Google is teasing a new line of "Googlebook" laptops for this fall, powered by a new Android-and-ChromeOS-derived operating system that will run Chrome, Android apps, phone-connected apps and files, and deeply integrated Gemini features. The company says Chromebooks will continue "after the launch of Googlebook" and "...all Chromebooks will continue to receive support through their device's existing date commitment." The Verge reports: "We'll have more to share on the exact OS branding later this year," Peter Du of Google's global communications team tells The Verge. [...] Googlebooks will have a Magic Pointer feature that offers contextual suggestions whenever you shake your cursor and point it at something on the screen. Google's examples include setting up a meeting by pointing at a date in an email or selecting images of furniture and a living space to visualize them together. Beyond your mouse pointer, Googlebooks will also feature the custom AI-created widgets that Google is also debuting today for Android phones and Wear OS smartwatches. I don't know what kind of horrors people will be able to make into widgets, but Google gives the example of making one to organize your flights, hotel information, restaurant reservations, and another for creating a countdown timer for an upcoming family reunion. (It's always flights, hotels, and restaurants, isn't it?) While there are many outstanding questions to be answered about Googlebooks, the biggest and most obvious ones are what will these laptops look like, what chips will be in them, and what will they cost? We've got none of that so far. Google only has some initial renders of a mysterious Googlebook and the promise that it's working with Acer, Asus, Dell, HP, and Lenovo to make the first models. There are no model names. No specs. Nada. Google isn't even saying if the laptop in its renders is made by a partner or a tease of some first-party Pixel-like Googlebook to come or is just a cool mockup. The one distinct hardware feature shown, the bar of glowing Google-colored light, will be a signature of all Googlebooks. (Sure, bring on the RGB. Why not?)

Microsoft and G42's planned $1 billion AI data center in Kenya has stalled amid disagreements over power commitments, with President William Ruto saying the country would need to "switch off half the country" to support the project at full scale. Tom's Hardware reports: The project, announced in May 2024 during Ruto's visit to Washington, was supposed to bring a geothermal-powered data center to the Olkaria region in Kenya's Rift Valley. G42 was to lead construction, with the facility running Microsoft Azure in a new East Africa cloud region. The first phase targeted 100 megawatts of capacity and was expected to be operational by this year, with a long-term goal of scaling to 1 gigawatt. President Ruto isn't exaggerating about shutting off half the country's power. Kenya's total installed electricity capacity sits between 3,000 and 3,200 megawatts, and peak demand reached a record 2,444 megawatts in January, according to data from KenGen, the country's government-owned electricity producer. The full 1 gigawatt build would therefore have consumed roughly a third of the country's total capacity, and even the first 100 megawatts would have required a significant share of the Olkaria geothermal complex's output, which currently generates around 950MW across all its plants. John Tanui, principal secretary at Kenya's Ministry of Information, told Bloomberg that the project hasn't been withdrawn and that talks are continuing, adding that the "scale of the data center they [Microsoft] wanted to do still requires some structuring." A separate 60-megawatt project with local developer EcoCloud is also still under discussion. [...] Microsoft is spending $190 billion on capex in 2026, and the company adds approximately 1 gigawatt of data center capacity every three months globally. But power constraints are proving to be a universal bottleneck: nearly half of planned U.S. data center builds this year have been delayed or canceled due to shortages of electrical infrastructure.

The EU plans to target "addictive design" features on TikTok, Instagram, and other platforms, including endless scrolling, autoplay, push notifications, and recommendation loops that can steer children toward harmful content. European Commission President Ursula von der Leyen said new regulation could arrive later this year, alongside an EU age-verification app meant to make child-safety rules easier to enforce. CNBC reports: "We are taking action against TikTok and its addictive design -- endless scrolling, autoplay, and push notifications. The same applies to Meta, because we believe Instagram and Facebook are failing to enforce their own minimum age of 13," Von der Leyen said. "We are investigating platforms that allow children to go down 'rabbit holes' of harmful content -- such as videos that promote eating disorders or self-harm," she added. The EU's executive arm has also developed its own age verification app, which has the "highest privacy standards in the world," according to Von der Leyen. Member states will soon be able to integrate it into their digital wallets, and it can easily be enforced by online platforms. "No more excuses -- the technology for age-verification is available," the EU chief said. The EU Commission could have a legal proposal prepared as soon as the summer, as it awaits the advice and findings of its 'Special Panel of experts on Child Safety Online.'

An anonymous reader quotes a report from Reuters: EBay on Tuesday rejected a $56 billion takeover bid from the much smaller GameStop over financing doubts, calling the proposal "neither credible nor attractive." EBay, which has roughly four times GameStop's market value, also underscored that its turnaround efforts under CEO Jamie Iannone have boosted growth, with its stock returning 201% since Iannone took the position six years ago. "We have concluded that your proposal is neither credible nor attractive," eBay Chairman Paul Pressler said in a statement. "eBay's Board is confident the company, under its current management team, is well-positioned to continue to drive sustainable growth." He also pointed to concerns with GameStop's bid, including its financing, its impact on eBay's long-term growth and the leadership structure of a potentially combined company. Last week, GameStop's CEO Ryan Cohen delivered one of the most memorable CNBC interviews in recent memory... initially disinterested, then increasingly hostile, with little eye contact, few real answers to basic questions, and repeated robotic deflections to "check the website." It's worth a watch if you have a few extra minutes.

The FCC has softened its ban on foreign-made consumer routers, allowing vendors to keep issuing broader software and firmware updates for devices already in use in the U.S. through at least January 2029. Dark Reading reports: Under the original FCC ruling, foreign manufacturers were permitted to provide only limited maintenance and security patches to US customers through March 2027. In a public note (PDF) on May 8, the FCC extended that deadline to at least January 2029 and also expanded the scope of permissible updates. The FCC will now allow foreign manufacturers to provide not just minor security fixes and changes, but also more major software and firmware updates that could affect router functionality, which previously required additional FCC review. The agency described the revisions as intended to ensure the continued safety of already deployed foreign-made consumer routers in the US. "The FCC likely issued this revision in response to the operational realities of network security and the slow pace of equipment replacement," says Jason Soroko, senior fellow at Sectigo. "Replacing millions of embedded devices across national infrastructure requires immense time and capital, and abandoning existing systems to a completely unpatched state would create an immediate vulnerability." "This waiver significantly alleviates the most pressing fears tied to the initial ban by preventing a sudden and dangerous security vacuum," added Soroko.
