The blog OMG Ubuntu reports that a new version of the Raspberry Pi 4 Model B has been (quietly) introduced. "The key difference? It now uses a dual-RAM configuration." The Raspberry Pi 4 Model B (PCB 13a) adopts a dual-RAM configuration to 'improve supply chain flexibility' and manufacturing efficiency, per a company product change notice document. Earlier versions of the Raspberry Pi 4 use a single RAM chip on the top of the board. The new revision adds a second LPDDR4 chip to the underside, with a couple of passive components also moved over... In moving to a dual-chip layout, Raspberry Pi can combine two smaller - and marginally cheaper - modules to hit the same RAM totals amidst fluctuating component costs... This change will not impact performance (for better or worse). The Broadcom BCM2711 SoC has a 32-bit wide memory interface so the bandwidth stays identical; this is not doubling the memory bus, it's just a physical split, not a logical one. Plus, the new board is fully compatible with existing official accessories, HATs and add-ons. All operating systems that support the Pi 4 will work, but as the memory setup is different a new version of the boot-loader will need to be flashed first.

"Elon Musk said on Sunday that SpaceX has shifted its focus to building a 'self-growing city' on the moon," reports Reuters, "which could be achieved in less than 10 years." SpaceX still intends to start on Musk's long-held ambition of a city on Mars within five to seven years, he wrote on his X social media platform, "but the overriding priority is securing the future of civilization and the Moon is faster." Musk's comments echo a Wall Street Journal report on Friday, stating that SpaceX has told investors it would prioritize going to the moon and attempt a trip to Mars at a later time, targeting March 2027 for an uncrewed lunar landing. As recently as last year, Musk said that he aimed to send an uncrewed mission to Mars by the end of 2026.

As Super Bowl Sunday comes to a close, America's National Football League "is challenging innovators to improve the facemask on football helmets to reduce concussions in the game," reports the Associated Press: The league announced on Friday at an innovation summit for the Super Bowl the next round in the HealthTECH Challenge series, a crowdsourced competition designed to accelerate the development of cutting-edge football helmets and new standards for player safety. The challenge invites inventors, engineers, startups, academic teams and established companies to improve the impact protection and design of football helmets through improvements to how facemasks absorb and reduce the effects of contact on the field... Most progress on helmet safety has come from improvements to the shell and padding, helping to reduce the overall rate of concussions. Working with the helmet industry, the league has brought in position-specific helmets, with those for quarterbacks, for example, having more padding in the back after data showed most concussions for QBs came when the back of the head slammed to the turf. But the facemask has mostly remained the same. This past season, 44% of in-game concussions resulted from impact to the player's facemask, up from 29% in 2015, according to data gathered by the NFL. "What we haven't seen over that period of time are any changes of any note to the facemask," [said Jeff Miller, the NFL's executive vice president overseeing player health and safety]... "Now we see, given the changes in our concussion numbers and injuries to players, that as changes are made to the helmet, fewer and fewer concussions are caused by hits to the shell, and more and more concussions as a percentage are by hits to the facemask..." Selected winners will receive up to $100,000 in aggregate funding, as well as expert development support to help move their concepts from the lab to the playing field. Winners will be announced in August, according to the article, "and Miller said he expected helmet manufacturers to start implementing any improvements into helmets soon after that."

If you use an Apple silicon Mac I'm sure you have been impressed by its performance. Whether you're working with images, audio, video or building software, we've enjoyed a new turn of speed since the M1 on day 1. While most attribute this to their Performance cores, as it goes with the name, much is in truth the result of the unsung Efficiency cores, and how they keep background tasks where they should be. ↫ Howard Oakley While both Intel and AMD are making gains on Apple, there's simply no denying the reality that Apple's M series of chips are leading the pack in mobile computing (the picture is different in desktops). There are probably hundreds of reasons why Apple has had this lead for so many years now, but the way macOS distributes background and foreground tasks across the two types of cores in M series chips is an important one. Still, I wonder how the various other processors that use power and efficiency cores fare in this regard. You'd think they would provide a similar level of benefit, but I wouldn't be surprised if the way Windows or Linux handles such cores and the distribution of tasks is simply not as optimised or strict as it is in macOS. Apple often vastly overstates the benefits of its "vertical integration", but I think the tight coupling between macOS and Apple's own processors is definitely a case where they're being entirely truthful.

We talked about Nemin's first impressions of the Guix System as someone coming from a Nix environment, but today they've got a follow-up article diving into the experience of creating new packages for Guix. I spent about a week packaging WezTerm and learning the ropes of being a Guix contributor along the way. During the packaging process I stumble many times, only to stand back up and figure out a solution. I also explain some of my complaints about the peculiarities of the process, but also provide plenty of praise about of how much the system tries to enable you to do your job. Finally, I also touch on how positive the experience of the code review was. ↫ Nemin's blog These are the kinds of content a rather niche system like Guix needs. Guix isn't exactly one of the popular picks out there, so having level-headed, honest, but well-written introductions to its core concepts and user experience, written by a third party is going to do wonders for people interested in trying it out.

It was only a matter of time before the illegal, erratic, inhumane, and cruel behaviours and policies of the second Trump regime were going to affect the open source world in a possibly very visible way. Christian Hergert, longtime GNOME and Linux contributor, employed by Red Hat, wanted to leave the US with his family and move to Europe, but requests to remain employed by Red Hat were denied. As such, he decided to end his employment at Red Hat and push on with the move. However, without employment, his work on open source software is going to suffer. While at their in-person visa appointment in Seattle, US border patrol goons shot two people only a few blocks away, underlining the urgency with which people might want to consider getting out of the US, even if it means losing employment. Regardless, the end result is that quite a bit of user-facing software that millions of people use every day is going to be affected. This move also means a professional shift. For many years, I've dedicated a substantial portion of my time to maintaining and developing key components across the GNOME platform and its surrounding ecosystem. These projects are widely used, including in major Linux distributions and enterprise environments, and they depend on steady, ongoing care. For many years, I've been putting in more than forty hours each week maintaining and advancing this stack. That level of unpaid or ad-hoc effort isn't something I can sustain, and my direct involvement going forward will be very limited. Given how widely this software is used in commercial and enterprise environments, long-term stewardship really needs to be backed by funded, dedicated work rather than spare-time contributions. ↫ Christian Hergert The list of projects for which Hergert is effectively the sole maintainer is long, and if you're a Linux user, odds are you're using at least some of them: GNOME's text editor, GNOME's terminal, GNOME's flagship IDE Builder, and tons of lower-level widely-used frameworks and libraries like GtkSourceView, libspelling, libpeas, and countless others. While new maintainers will definitely be found for at least some of these, the disruption will be real and will be felt beyond these projects alone. There's also the possibility that Hergert won't be the only prolific open source contributor seeking to leave the US and thus reducing their contributions, especially if a company like Red Hat makes it a policy not to help its employees trying to flee whatever mess the US is in. Stories like these illustrate so well why the "no politics!" crowd is so utterly misguided. Politics governs every aspect of our lives, especially so if you're part of a minority group currently being targeted by the largest and most powerful state apparatus in the world, and pretending to be all three wise monkeys at once is not going to make any of that go away. Even if you're not directly targeted because you're not transgender, you're not brown, you're not an immigrant, or not whatever else they fancy targeting today, the growing tendrils of even an incompetent totalitarian regime will eventually find you and harm you. More so than any other type of software, open source software is made by real humans, and as these totalitarian tendrils keep growing, more and more of these real humans will be affected, no matter how incompetent these tendrils might be. You can't run away and hide from that reality, even if it makes you uncomfortable.

While starting this post I realized I have been maintaining personal infrastructure for over a decade! Most of the things I've self-hosted is been for personal uses. Email server, a blog, an IRC server, image hosting, RSS reader and so on. All of these things has all been a bit all over the place and never properly streamlined. Some has been in containers, some has just been flat files with a nginx service in front and some has been a random installed Debian package from somewhere I just forgot.

In the recent blog post on the work funded by Sovereign Tech Fund (STF), we provided an overview of the "File Hierarchy for the Verification of OS Artifacts" (VOA) and the voa project as its reference implementation. VOA is a generic framework for verifying any kind of distribution artifacts (i.e. files) using arbitrary signature verification technologies. The voa CLI ⌨️ The voa project offers the voa(1) command line interface (CLI) which makes use of the voa(5) configuration file format for technology backends. It is recommended to read the respective man pages to get …
