joshuark shares a report from Wired: After 22 years in orbit and a failed rescue mission this summer, it is highly likely that the Neil Gehrels Swift Observatory will crash into Earth sometime next week. It is not known where on the planet the spacecraft -- which is roughly as big as a large elevator -- will fall. Despite its size, experts say the risk to the public is relatively low. The observatory was designed to operate for a few years in low Earth orbit, but it far exceeded its expected lifespan, helping to make many important discoveries about the evolution of the cosmos, including the study of supernovas and the destruction of stars by black holes. However, in 2024, increased solar activity heated and expanded the upper layers of Earth's atmosphere, increasing the drag on the satellite and accelerating its descent. Without a propulsion system capable of correcting its orbit, its days were numbered. The U.S. Space Force now expects Swift to reenter Earth's atmosphere around November 6. Most of the spacecraft is expected to burn up, although some components could survive and reach the ground (but most likely the ocean). "The most likely survivors are its six heavy reaction wheels, the spinning flywheels it used to aim itself, along with tougher telescope parts such as lenses and mirrors," Dean Sladen, a quality manager and aerospace engineer at Accu Components, told Space.com. "Only a handful of small, scorched fragments are expected to make it down -- nothing recognizable as a telescope." "NASA's own orbital debris requirements state that the risk of human casualty from surviving debris shall not exceed one in 10,000, so it is highly likely this work has been completed but not published," Sladen said regarding the risk assessment. "Personally, I believe it should be published, as NASA has done with previous satellites. The risk is almost certainly very small, but it would give people a clear, factual picture rather than guesswork."

Researchers have confirmed the presence of intact biomolecules and mineralized red blood cells inside the 115-million-year-old fossilized bones of a juvenile Aratasaurus museunacionali from Brazil. The discovery challenges assumptions about how long blood-related biomolecules can survive and could help scientists study dinosaur metabolism, blood evolution and even how traces of ancient life might be preserved on other worlds. Popular Science reports: The evidence exists inside the fossilized limb bones of a juvenile Aratasaurus museunacionali. Discovered in 2008, A. museunacionali was an Early Cretaceous theropod that lived in present-day northeastern Brazil. The fossils suggest a dinosaur measuring over 10 feet long and weighing about 75 pounds, but given its young age, A. museunacionali likely grew even larger. After carefully examining thin slices of the fossils, paleontologists located the mineralized red blood cell molecular components, along with a complex manganese oxide called hausmannite. This material helped maintain the cellular structures of heme, a ring-shaped molecule that contains iron and binds many proteins, especially hemoglobin. The hausmannite also helped preserve additional biomolecules found in the blood, such as the amino acids in collagen. The study's authors theorize this level of preservation could only occur following a rapid burial in an environment that was rich in microbes, but low in oxygen at the same time. The findings have been published in the journal Proceedings of the National Academy of Sciences (PNAS).

Tuesday, November 3, was Election Day in the United States, and the results are (mostly) in: Democrats are projected to win control of both the House and Senate in the 2026 midterms. The blue wave turned out to be more of a blue tsunami, ending Republican control of Congress for the final two years of President Donald Trump's second term. Democrats flipped seven Republican-held Senate seats in the 2026 midterms, including surprise victories in traditionally Republican strongholds such as Texas, Kansas, and South Carolina. Kansas elected its first Democratic U.S. senator in nearly 100 years (94 years to be exact), while Texas and South Carolina sent Democrats to the Senate for the first time in decades. Democrats also picked up seats in Ohio, Iowa, Maine, and North Carolina. Developing...

Enlightenment, the long-running desktop environment and associated libraries and frameworks, just released version 0.28.0. It brings initial support for NetBSD, support for Network Manager and a whole slew of related changes and fixes to make that possible, as well as native PipeWire support. There's also a brand new clipboard manager, which brings with it modernisations and bug fixes for related UI elements. This release also reworks a ton code related to battery management, AC polling, and more, adding features like setting battery thresholds, ACPI power profile support, and so on. Of course, there's also the long list of smaller fixes and changes. You can download the release and build it yourself, or wait for your distribution of BSD variant to package it.

A little while ago, we talked about 9front's Good Enough File System being ported to OpenBSD. A lot of progress has been made on this front lately. Aside from fixing bugs and porting over fixes from the 9front side, there's also been a ton more substantial changes. Some userspace tools have been done (you can now mkfs on openbsd!), but snapshot control hasn't. I'm thinking we have a userspace 'gefs' program that lets you handle this, trying to keep the interface similar to the 9front ctl file. ↫ Ori Bernstein There's still some major hurdles to overcome, some of which have already been addressed on the 9front side, but the progress is clear. Considering OpenBSD desperately needs a more modern file system, this is great news. A fun sidenote is that I'm actually posting this news item from OpenBSD.

"From a global allocation perspective, actually, it's quite terrible to have everybody have a bunch of the world's limited supply of DRAM sitting in their own computer and being used 5% of the time," Altman said. "You want maximum utilization in the cloud if you're trying to deal with this very supply-constrained environment. And somehow many people's intuition is the opposite of that." ↫ Andrew E.

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 …
