Longtime Slashdot reader destinyland shares a report from CNN: The Pentagon has given the Department of Homeland Security permission to test a military-grade heat ray and develop tactics to potentially use it in operations at the southern US border, according to a memo signed by Defense Secretary Pete Hegseth last month and obtained by CNN. The heat ray, officially known as the Active Denial System, is a nonlethal weapon that shoots an invisible beam of electromagnetic waves that can reach a little more than half a mile away, according to the US military. The energy beam causes a burning sensation when it comes into contact with the human skin -- which Pentagon officials have previously compared to feeling a blast of heat when opening a hot oven. Military officials have said the resulting "tingling effect" lasts between 10 and 15 minutes but also generates "an instinctive and irresistible urge to run from the effect."

Graybeards like me remember trying to painstakingly type source code from a magazine. This is a very accurate account of what a young computer user in 1986 needed to do to get a new game for the Commodore 64, complete with an immersive emulation. It's time to install an app! But here in 1986, we still call them "programs," not apps. So, you'll want to set aside some time to get started installing a program.

An anonymous reader quotes a report from The New York Times: For the first time, scientists say they have used viruses designed by artificial intelligence to treat a human patient. Researchers announced on Tuesday that they had administered the virus, known as a phage, to a patient suffering from a deadly bacterial infection. Phages attack bacteria, and the hope is that this one will kill the microbes causing the infection. Radical Numerics, the start-up that created the viruses, posted a technical report about them on its website. But the company declined to provide information about the patient or the doctors running the trial, citing confidentiality requirements. [...] In 2025, researchers at the Arc Institute in Palo Alto, Calif., created an A.I. model called Evo 2, which they trained on millions of DNA sequences, including phage genes. They prompted Evo 2 to make new genomes similar to those in a group of phage species. The A.I. generated 700,000 virus genomes. The team synthesized DNA molecules from 285 genomes and inserted them into bacteria. The researchers found that 16 of the genomes gave rise to viable viruses. Three members of the Evo team, including Dr. Nguyen, left to found Radical Numerics. In June, the company unveiled a new A.I. model, called Omnii, based on some of the same principles as Evo. Omnii can be trained not just on DNA but also on other aspects of biology, such as the structures of proteins and molecules that keep genes turned on or off. The company is now using Omnii to tackle a range of challenges, including designing cancer vaccines and recognizing the risk that a virus may cause a pandemic. Among these efforts is the first trial of A.I.-designed phage therapy. The researchers created variations of a phage called T7. The virus, which only infects E. coli, looks like a microscopic Apollo lunar lander: a ball-shaped protein shell that holds its DNA atop six leglike protrusions. To infect a bacterium, T7 lands on its surface, using its legs to anchor in place. It then injects its DNA into the cell. Omnii generated new viral genes altering the shapes of T7's legs, according to Dr. Nguyen and his colleagues. While some of the new legs were significantly different from natural ones, Omnii's phages could still infect bacteria. Once the researchers were confident their strategy had worked, they partnered with doctors treating a patient with a stubborn E. coli infection. The bacteria had resisted not just antibiotics but all the available phages. The researchers said they had trained Omnii with information about the resistant strain and told it to design T7 phages with legs that could grab onto the bacteria. Once the A.I. generated genomes for new viruses, the scientists said they produced the corresponding DNA molecules and inserted them in bacteria. The bacteria became infected and produced T7 phages that could successfully infect, and kill, other microbes. After running tests to make sure the phages were safe, Radical Numerics presented them to the doctors. The F.D.A. authorized a trial. While the trial was authorized by the FDA, it's worth noting that the research has not yet been peer-reviewed in a scientific journal and there's no guarantee the AI-designed phages will work. However, if it does prove successful, it could help speed phage therapy by cutting down the time it takes to create a new virus tailored to each patient's infection. "We think we can get it done in days," said Dr. Eric Nguyen, the chief executive officer of Radical Numerics.

eBay plans to cut about 1,000 jobs, or 9% of its workforce, as CEO Jamie Iannone moves to redirect resources toward the company's fastest-growing businesses. Reuters reports: The company had 12,300 employees at the end of last year. It also let go about 6% of its workforce, or 800 employees, in February as part of efforts to streamline operations. EBay has set itself apart from rivals by pushing into authenticated luxury goods, collectibles and refurbished products, which draw enthusiasts willing to pay more for valuable items. That has helped its shares rise nearly 40% this year, outperforming the benchmark S&P 500's around 12% gain. "Our strategy is working," Iannone said in the memo, adding that "continuing to capture the significant opportunity ahead requires us to make thoughtful choices about where we focus and invest." He said affected staff would be informed in the coming days.

Early 2025, I wrote about how I think macOS' UNIX certification was basically a lie. It required so many convoluted and cumbersome changes to macOS that literally nobody applies to their system that it the certification had kind of become a farce. At the end of the article I wondered for how much longer Apple would be playing this little charade to hammer macOS through a meaningless UNIX-shaped hole, and it turns out the answer was "about 18 months". When you go to the Open Group's website and the list of certified UNIX operating systems, macOS is no longer listed. For the past few weeks, it was still listed if you drilled down specifically to the UNIX 03 certification, but that, too, has now been removed. Assuming macOS 27 doesn't return in the near future with a brand new certification, we can safely say that Apple got tired of paying a few employees to get its desktop operating system certified. With one more operating system gone from the list, there's now only one UNIX operating systems left: AIX. While the registry also lists HP-UX, z/OS, and UnixWare/OpenServer, those either only conform to really old UNIX certifications (from the '90s), or simply aren't developed anymore (HP sunset HP-UX at the end of last year). Only one operating system version conforms to the latest version of the certification, UNIX 07, and that's AIX 7.2 TL5 "and later", which possibly includes AIX 7.3, the most recent version of AIX. Not that any of this really matters.

This is a story of how we got from something like this: Failed to deserialize BUILDINFO file: Parser failed with the following error: unknown ^ invalid makepkg build environment option expected `buildflags`, `ccache`, `check`, `color`, `distcc`, `sign`, `makeflags` To this: When the ALPM project started, the goal was fairly simple: Better tooling to interact with the low-level plumbing of Arch Linux Package Management (ALPM). This meant binaries to read/write individual file types, better error messages, extensive specifications and of course exports to common dataformats like JSON. The thing is, although some of us already had experience with low-level dataframe parsing, …

Over the last few weeks, we have been doing research on the integration of our official distribution packages when installed on a target system. In this context we have been looking at the current uses of alpm-install-scriptlet(5) files and alpm-hooks(5) in around 120 package source repositories (alpm-source-repo(7)) to better understand the underlying functionality and use-cases these two integrations offer and target. In this article we are going to look at how these two systems work, how Arch Linux is currently using them and attempt to provide suggestions for when to use which. Learning about alpm-hooks(5) and alpm-install-scriptlet(5) files …
