"For developers and organisations that require a custom software image, a flexible and transparent build system is essential," according to an announcement Friday at Raspberry Pi.com. "[T]o support these customers, we have created rpi-image-gen, a powerful new tool designed to put you in complete control of your Raspberry Pi images." If you're building an embedded system or an industrial controller, you'll need complete control over the software resident on the device, and home users may wish to build their own OS and have it pre-configured exactly the way they want... rpi-image-gen is an alternative to pi-gen, which is the tool we use to create and deploy the Raspberry Pi OS distribution. rpi-image-gen... offers a very granular level of control over file system construction and software image creation... [B]eing able to help reduce software build time, provide guaranteed ownership of support, and reuse standard methodologies to ensure authenticity of software were all of paramount importance, and among the reasons why we created a new home-grown build tool for Raspberry Pi devices... There is a small number of examples in the tree which demonstrate different use cases of rpi-image-gen [including the lightweight image slim and webkiosk for booting into browser kiosk mode]. All create bootable disk images and serve to illustrate how one might use rpi-image-gen to create a bespoke image for a particular purpose. The number of examples will grow over time and we welcome suggestions for new ones... Visit the rpi-image-gen GitHub repository to get started. There, you'll find documentation and examples to guide you through creating custom Raspberry Pi images. Some technical details from the announcement. "Similar to pi-gen, rpi-image-gen leverages the power, reliability, and trust of installing a Debian Linux system for the device. However, unlike pi-gen, rpi-image-gen introduces some new concepts [profiles, image layouts, and config] which serve to dictate the build footprint and installation." The tool also lets you exclude from your package "things that would otherwise be installed as part of the profile." The tool's GitHub repository notes that it also allows you output your software bill of materials (SBOM) "to list the exact set of packages that were used to create the image." And it can even generate a list of CVEs identified from the SBOM to "give consumers of your image confidence that your image does not contain any known vulnerabilities."

Science magazine reports: A strange-looking telescope that scanned the skies from a perch in northern Chile for 15 years has released its final data set: detailed maps of the infant universe showing the roiling clouds of hydrogen and helium gas that would one day coalesce into the stars and galaxies we see today. The Atacama Cosmology Telescope is not the first to survey the cosmic microwave background (CMB), the light released 380,000 years after the Big Bang when the early universe's soup of particles formed atoms and space became transparent. But the data — posted as preprints online today — give researchers a new level of detail on the density of the gas clouds and how they were moving. At the top of the page for Science's article is an image where different colors "show areas where the polarization of the CMB light — its direction of vibration — differ, revealing how gases first move tangentially around areas of higher density (orange) and later fall straight in (blue) under the influence of gravity." Long-time Slashdot reader sciencehabit writes: Using the data, researchers tested how well the standard cosmological theory, known as lambda cold dark matter, described the universe at that time 13.8 billion years ago; it's a remarkably good fit, they conclude. The article notes that "back in the Chilean desert," the Atacama Cosmology Telescope's successor, the Simons Observatory, has already taken its first image, and "will begin its even more detailed examination of the CMB in the coming months."

Wired's web site "is going to stop paywalling articles that are primarily based on public records obtained through the Freedom of Information Act," their global editorial director announced this week: They're called public records for a reason, after all. And access to public documents is more important than ever at this moment, with government websites and records disappearing... [S]ome may argue that, from a business standpoint, not charging for stories primarily relying on public records automatically means fewer subscriptions and therefore less revenue. We disagree. Sure, the FOIA process is time- and labor-intensive. Reporters face stonewalling, baseless denials, lengthy appeals processes, and countless other obstacles and delays. Investigative reports based on public records are among the most expensive stories to produce and share with the public... But while some readers might not subscribe to outlets that give away some of their best journalism for free, it's just as possible that readers will recognize this sacrifice and reward these outlets with more traffic and subscriptions in the long run... We hope others will follow Wired's lead (and shoutout to outlets like 404 Media that also make their FOIA-based reporting available for free). We also hope those who stand to benefit from these outlets' leadership (that's you, reader) will do their part and subscribe if you can afford it. They're not asking for an arm and a leg... The Fourth Estate needs to step up and invest in serving the public during these unprecedented times. And the public needs to return the favor and support quality journalism, so that hopefully one day we can do away with those annoying paywalls altogether.
