Japan has successfully launched its Martian Moons eXploration (MMX) mission to study Mars' two moons, Phobos and Deimos. Scheduled to arrive in August 2027, "MMX will become the first spacecraft to land on and return samples from Phobos for study back on Earth, which scientists think could shed light on a decades-old mystery about the moons' origins" and resolve whether they were formed from a giant impact or were captured asteroids, reports Space.com. From the report: It was the 10th liftoff of Japan's expendable, two-stage H3 rocket, which was jointly developed by JAXA and Mitsubishi Heavy Industries. After clearing its launch pad today, the 207-foot-tall (63 meters) launch vehicle flew a nominal trajectory through its ascent corridor over the Pacific Ocean, jettisoning its four solid boosters in pairs just before the flight clock reached two minutes. The rocket shed its payload fairings about one minute and 20 seconds later, exposing MMX to the vacuum of space for the first time. [...] MMX is now under its own power, and on course for Mars. The interplanetary transit will last about 10 months, with the spacecraft scheduled to arrive at the Red Planet in August 2027. When it does, MMX's propulsion module will execute an orbital insertion burn to place itself in a quasi-satellite orbit (QSO) around Phobos, which places MMX within the space around the moon as both circle Mars. MMX will spend about three years in the Martian system, devoting much of that time to studying the 14-mile-wide (22 km) Phobos with its science instruments. The spacecraft also carries the IDEFIX rover, a joint effort of the space agencies of France and Germany, which is scheduled to deploy to the surface of Phobos in late 2028 or early 2029. After a mapping campaign to select suitable landing sites, MMX will perform two separate touchdowns on Phobos to collect and stow samples in the spacecraft's return capsule. Following its second landing and sample collection, MMX will briefly return to QSO with Phobos before transferring to a more elongated orbit around Mars that intersects with the planet's smaller moon, Deimos, which is just 8 miles (14 km) in diameter. During the last several months of its time around Mars, MMX will perform a series of Deimos flybys before departing for Earth in November 2030. If all goes according to plan, the MMX sample-return capsule will land in Australia in 2031. You can watch a recording of the launch on YouTube.

The climax for MMX will come in 2029, when the spacecraft will attempt up to two landings on Phobos.

An anonymous reader quotes a report from TechCrunch: Amazon is funding development of a proposed 960-megawatt nuclear plant in Indiana and would be the first customer to buy its power, the companies announced Monday. Utility company American Electric Power (AEP) would operate the plant. X-energy, which designs small modular nuclear reactors and went public in April, would supply the reactors. The new power plant would consist of 12 Xe-100 small modular reactors and be located on the site of a demolished coal power plant just south of Terre Haute. The deal is the second commercial agreement between Amazon and X-energy, and it's three times larger than the first, which was announced two years ago. Amazon has invested heavily in X-energy, leading a $700 million Series C-1 round in October 2024. The two companies have said they ultimately plan to build 5 gigawatts of new nuclear generating capacity in the U.S. by 2039. Unlike many newly announced power plants, these reactors would be connected to the public electric grid, though Amazon says the power would also serve its data centers. The companies' aggressive timeline still depends on X-energy successfully delivering its first power plant at a Dow Chemical plant southeast of Houston, Texas. The site, called Seadrift, has recently been at the center of a lawsuit filed by the state of Texas, which accuses the plant of "habitual non-compliance" with water and solid-waste regulations and permits. X-energy has yet to break ground at Seadrift, which will host four Xe-100 reactors to provide the chemical plant with heat and electricity. The company said its construction permit is in the final phases of the U.S. Nuclear Regulatory Commission's review process.

joshuark writes: Professor Christopher Marquis makes a provocative argument about business schools: "We need to abolish them." A 20-year business educator at Harvard, Cornell and Cambridge, Marquis argues in The New York Times and on LinkedIn that MBA programs sanctify profit-driven dealmaking at the expense of public life. "That's not the institution failing," he writes. "Sadly, it's the institution working." "Business school doesn't just hand out skills and a network," argues Marquis, "it quietly reshapes how people see the world, rewarding dealmaking, simplification, and optimization for financial metrics, while workers and communities become afterthoughts." Marquis points to research suggesting that business-school-trained CEOs often benefit shareholders at the expense of workers, without delivering measurable improvements in company performance... "[W]hen a business-school-trained CEO takes over a firm, wages fall and labor's share of income drops, with no gain in productivity," writes Marquis. "In both the U.S. and Denmark, what passes for the 'managerial skill' of business-school graduates turns out to be a transfer of wealth away from workers and toward shareholders. Students deserve better than a machine that narrows their sense of what's possible."

Apparently, macOS 27 comes with a small mystery people are trying to figure out. Recently, while troubleshooting a PATH issue, I noticed an entry for /pkg/env/global/bin. At first, I worried that something had gone horribly wrong. Turns out, this is part of macOS 27.0… though no one is sure what it's for yet. In a post about how macOS's boot volume structure has been updated, Howard Oakley explains that the pkg directory was added to the Data volume in macOS 26.4, but not added to the root of the Signed System Volume until 27.0. He also notes that this is sort of a big deal. The weird thing is, as far as I can tell, no one seems to know what this new directory is for! It's odd that Apple would update their filesystem structure, add it to everyone's PATH, and there not be some explicable reason. ↫ Gavin Anderegg I guess we'll find out eventually, but this does highlight something that I find extremely unsettling about this. With proprietary software like macOS, you literally are at the mercy of whatever Apple decides to do to "your" operating system. You install an update, and aside from all the documented changes, there's going to be changes you simply have no idea what they're for, or why they're there. Don't get me wrong, there's obviously not something nefarious going on in this particular case, but it still feels wild to me that people just willingly accept this. In the open source world, stuff like this simply does not happen. You're not going to install a bunch of Fedora updates one day and find a mysterious, undocumented folder in your PATH. Such a change will be documented, but even in the unlikely event it's not, you can just go through the commit history and find out exactly why the new folder is there, and what its intended purpose is or is going to be. Considering the state of the world and the people corporations like Apple really answer to, I would not be comfortable with letting them dictate even something as simple as my PATH.

In what is quite a major achievement, Wine has been ported and made to work on OpenBSD. We have since tested several dozens of 64-bit Windows software, mostly successfully. See screenshots, livestream recordings for example. Even the Remaster of The Witcher 3 which released just last month runs, and runs well (requires adding in vkd3d-proton; see README; livestream which looks less fluent than it is due to the on-system recording with ffmpeg). ↫ Thomas Frohwein The biggest limitation seems to be the lack of support for WoW64, so 32bit Windows software won't work. Still, this is a massive milestone for OpenBSD, and makes especially gaming a somewhat viable option on OpenBSD.

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 …
