DOT Announces 'Return of Supersonic Flight' For Commercial Airlines

The FAA plans to replace its 1973 ban on civilian supersonic flight over U.S. land with a noise-based standard, potentially allowing aircraft to exceed Mach 1 as long as they stay below certain sound limits. The agency aims to finalize the rules by mid-2027, opening the door for companies such as Boom Supersonic and Spike Aerospace to operate quieter next-generation passenger jets over land. Longtime Slashdot reader schwit1 shared the notice (PDF) published Tuesday by the FAA. Forbes reports: Technological advances "will eliminate the old sonic boom," FAA Administrator Bryan Bedford said in a statement. "This means we can ultimately repeal the ban from the 1970s on supersonic flight over U.S. territory while minimizing noise impacts to residents in communities along the route and near airports." The primary reason was public opposition to loud sonic booms. In the 1960s, a plane flying faster than the speed of sound -- about 660 mph at high altitudes -- created shock waves that traveled to the ground and reached human ears as a loud gunshot-like crack or thunder-like boom. Tests during that decade, including the Oklahoma City sonic boom experiments, found repeated booms broke windows, damaged property and generated thousands of public complaints. In its 1973 ruling, the FAA stated that due to the limits of technology at that time, "a prohibition was needed to protect the public from sonic boom .... by preventing operations of a civil aircraft at a true flight Mach number greater than 1." Several years later, Air France and British Airways introduced Concorde, and were allowed to serve New York's John F. Kennedy International Airport as long as flights remained subsonic over U.S. land. Notably, "the prestigious London-New York service was the only truly profitable [Concorde] route, supported by high-powered business and celebrity travel," wrote a former British Airways network planner for Forbes in 2021. Several U.S. companies are working on a new generation of luxurious supersonic passenger aircraft with much quieter sonic booms and improved fuel efficiency. In particular, Colorado-headquartered Boom Supersonic says it has pre-orders from United Airlines, American Airlines and Japan Airlines for its Overture jets, which will carry 60-80 passengers. Atlanta-based Spike Aerospace is developing smaller Diplomat jets for up to 18 passengers. Both companies' websites tout future transatlantic flights in under four hours.

Trump Drops Restrictions On Anthropic's Mythos and Fable Models

The Trump administration has lifted export restrictions that forced Anthropic to shut off public access to its Mythos and Fable models. After weeks of talks, Secretary of Commerce Howard Lutnick said Anthropic "has agreed to proactively detect and address security risks associated with the models; to work diligently with the U.S. government on protocols and standards and releases for Mythos, Fable and future models; and to inform the US government of any malicious activity." Access is set to begin returning July 1. TechCrunch reports: Anthropic had already publicly pledged to do much of this voluntarily, months before the export rule existed. That's part of why cybersecurity experts were skeptical of the restrictions in the first place. To them, the ban looked less like a security fix and more like leverage, a way for the Trump administration to punish Anthropic for its executives' public criticism of how the government, and the president's political opponents, might use the technology. Mythos was originally made available to a select group of organizations beginning in April to allay concerns about its ability to identify and exploit vulnerabilities in software, while a version called Fable was released to the public in June with additional security guardrails. However, with Asian AI companies beginning to release their own AI models approaching Mythos-level capabilities -- among them Fugu and Tulonfeng -- the US government was under pressure to ease its restrictions on Anthropic to ensure that American AI could compete globally. Last week, Lutnick cleared Mythos to be released to select customers approved by the White House. OpenAI's latest models were also released to a group of organizations approved by the Trump team, instead of the public. The Trump administration's erratic approach to AI policymaking has left companies across the industry with little clarity about what will govern future model releases. An executive order issued in June that signaled a desire to review models ahead of release was criticized by influential analysts like Dean W. Ball, who recently started a policy position at OpenAI.

New Florida Law Bans Local Net-Zero Emissions Policies

An anonymous reader quotes a report from Inside Climate News: A new state law limits Florida communities' aims to offset greenhouse gas emissions that are warming the global climate and intensifying disasters such as hurricanes. Specifically, HB 1217 prohibits local governments from pursuing net-zero emissions goals. At least 10 cities and counties have implemented such policies, including Fort Lauderdale, Miami, Orlando and Leon County, where Tallahassee, the state capital, is located. But the new law will not necessarily upend these policies, said Bradley Marshall, senior attorney at Earthjustice, an advocacy group. "It's certainly meant to scare municipalities and local governments from trying to do things to further net-zero policies," he said. "Now, its exact impact and what it exactly prohibits is probably up for some debate. Things that are adjacent to it -- emissions reductions and even climate change reduction policies -- on their face will not run afoul at all of a ban on adopting a net zero policy." The measure requires local governments to submit an affidavit annually to the state Department of Revenue verifying compliance. Gov. Ron DeSantis, a Republican, signed the measure on April 22, Earth Day, and the law will take effect July 1. It states that "net zero policies, carbon taxes and assessments, and emission trading programs are detrimental to this state's energy security and economic interests and inconsistent with the energy policy and the environmental policy of this state." [...] HB 1217 also prevents local governments from purchasing items such as vehicles or appliances based on the fuels they use or production of the items. Local governments may not participate in carbon-trading programs or use public funds to support other organizations with net-zero policies. Cities and counties also may not charge a tax or fee tied with carbon emissions. "This bill is definitely part of a larger coordinated push by the political enablers of the fossil fuel industry to obstruct any tools -- legal or legislative tools -- to hold the industry accountable for its contributions to climate change," said Laura Peterson, senior analyst at the Union for Concerned Scientists, an advocacy group. "Florida is really on the front lines. So I imagine the governor is taking this step because he sees what's coming down the pike. It's not getting better. So I can only assume that this is an effort to satisfy some of the pressures that he's getting from donors and from his party to protect the industry. And he's doing it at the expense of his constituents."

Microsoft now says 8GB RAM is fine for Windows 11, after years of pushing for 16GB

There's something poetic about the World Cup taking place in North America while Microsoft keeps scoring own goals like this. Microsoft updated its Surface buying guide to describe 8GB RAM as "great for everyday use like browsing, streaming, schoolwork, and productivity apps." A companion FAQ adds that 16GB or more is what unlocks Copilot+ PC features. No acknowledgment that, for two years, Microsoft was the loudest voice telling everyone that 16GB was non-negotiable for a good Windows 11 experience. What makes this infuriating is that Microsoft is one of the biggest reasons why the RAM situation got so bad in the first place. ↫ Abhijith M B at Windows Latest This industry is a joke.

Astral is a hobby operating system with X.org, Minecraft, and now Wine

Astral is a hobby operating system written in C for 64bit architectures, with a collection of ported software like X.org, fvwm, the xbps package manager, and tons more. I think it's quite a neat system - the code's on GitHub - made even neater by the fact it can run not only Minecraft, but now also has a working port of Wine that can run a few games. A few months ago, I posted about Astral, a hobby OS I have been working on over the years, running Minecraft. Since then, others have gotten modern versions of Minecraft to run as well as Factorio (using a glibc compatible libc). However, while these games are made or packaged in a way that makes it easier to get them to run under a new OS, most games are not. A lot of games are closed source and compiled for Windows, which makes something like Wine a necessity for playing them. One of my favorite games, Cogmind, falls under that umbrella. It is a 32-bit Windows only roguelike, and it became my goal to run it under Astral. While there was already an existing Wine port, it was extremely incomplete, as not even notepad.exe worked properly. To run Cogmind, the Wine port had to be finished, which also meant adding the ability to run 32-bit code on an otherwise 64-bit-only OS. ↫ Blog post on the Astral website This process obviously is quite involved, but in the end, they managed to get it working. Quite impressive.

The ‘papers, please’ era of the internet will decimate your privacy

Imagine your favorite team just scored an incredible, last-second goal at the World Cup. So you log online to celebrate with other fans. But, using data it's already collected on you, the social media platform you like to post on wrongly guesses that you're under 16 so it forces you to go to a third-party verification app and provide images of your face or your government-issued ID. You don't really know much about the verification app, what country it's based out of, what happens with your information, and whether you're protected from hackers or data breaches. You're not happy about it, but you hand over a photo of your passport and hope it doesn't come back to haunt you. Now imagine that instead of posting about sports, you're criticizing a powerful politician, or talking about your experiences with abuse or addiction, or discussing embarrassing medical issues you're facing. Suddenly this "papers, please" approach to the internet sounds even more invasive, right? Unfortunately, that's the direction we're all headed - even here in the United States - and we have good reason to be wary of the global rush to sacrifice user privacy on the altar of age verification. ↫ Sarah McLaughlin at Expression The insane push for age verification on the internet is the biggest threat to whatever's left of the free internet. I have two young children - 3 and 5, currently - and I'm diametrically opposed to any kind of creepy verification processes that they claim are designed to keep kids like mine "safe". Not only is their safety not predicated on giving up their privacy, my children are also not my or anyone else's property; they have rights, and the right to privacy is one of them. Nobody mentioned in the Epstein files has been charged, by the way.
