Scientists Found a Way To Cool Quantum Computers Using Noise

Slashdot.org - Sat, 01/31/2026 - 12:34
Slashdot reader alternative_right writes: Quantum computers need extreme cold to work, but the very systems that keep them cold also create noise that can destroy fragile quantum information. Scientists in Sweden have now flipped that problem on its head by building a tiny quantum refrigerator that actually uses noise to drive cooling instead of fighting it. By carefully steering heat at unimaginably small scales, the device can act as a refrigerator, heat engine, or energy amplifier inside quantum circuits.

Author of Systemd Quits Microsoft To Prove Linux Can Be Trusted

Linux.Slashdot.org - Sat, 01/31/2026 - 05:00
Lennart Poettering has left Microsoft to co-found Amutable, a new Berlin-based company aiming to bring cryptographically verifiable integrity and deterministic trust guarantees to Linux systems. He said in a post on Mastodon that his "role in upstream maintenance for the Linux kernel will continue as it always has." Poettering will also continue to remain deeply involved in the systemd ecosystem. The Register reports: Linux celeb Lennart Poettering has left Microsoft and co-founded a new company, Amutable, with Chris Kuhl and Christian Brauner. Poettering is best known for systemd. After a lengthy stint at Red Hat, he joined Microsoft in 2022. Kuhl was a Microsoft employee until last year, and Brauner, who also joined Microsoft in 2022, left this month. [...] It is unclear why Poettering decided to leave Microsoft. We asked the company to comment but have not received a response. Other than the announcement of systemd 259 in December, Poettering's blog has been silent on the matter, aside from the announcement of Amutable this week. In its first post, the Amutable team wrote: "Over the coming months, we'll be pouring foundations for verification and building robust capabilities on top." It will be interesting to see what form this takes. In addition to Poettering, the lead developer of systemd, Amutable's team includes contributors and maintainers for projects such as Linux, Kubernetes, and containerd. Its members are also very familiar with the likes of Debian, Fedora, SUSE, and Ubuntu.

Linux Gaming Developers Join Forces To Form the Open Gaming Collective

Linux.Slashdot.org - Thu, 01/29/2026 - 19:45
A group of Linux gaming-focused distros and developers have formed the Open Gaming Collective to pool work on shared components like kernels, input systems, and Valve tooling. The Verge reports: Universal Blue, developer of the gaming-focused Linux distribution Bazzite, announced on Wednesday that its helping to form the OGC with several other groups, which will collaborate on improvements to the Linux gaming ecosystem and âoecentralize efforts around critical components like kernel patches, input tooling, and essential gaming packages such as gamescope." The other founding members of the OGC include Nobara, ChimeraOS, Playtron, Fyra Labs, PikaOS, ShadowBlip, and Asus Linux. [...] It's worth noting that this will mean some changes to Bazzite, which is switching to the OGC kernel, replacing HHD with InputPlumber as its input framework, and integrating features like RGB and fan control into the Steam UI. Bazzite also added that, "We'll be sharing patches we've made to various Valve packages with the OGC and attempting to upstream everything we can."

Nvidia GeForce NOW Is Now Available Natively On Linux

Linux.Slashdot.org - Thu, 01/29/2026 - 17:40
NVIDIA has officially launched a native GeForce NOW client for Linux as a Flatpak, giving Linux gamers access to cloud-rendered RTX gaming. Phoronix reports: While confined to a Flatpak, for now NVIDIA is just "officially" supporting it on Ubuntu 24.04 LTS and later. Granted, thanks to Flatpak it should run on other non-Ubuntu distributions too but in terms of the official support and where they are qualifying their builds they are limiting it just to Ubuntu 24.04 LTS and later. [...] At launch the Flatpak build is also just for x86_64 Linux with no AArch64 Linux builds or similar at this time. Running GeForce NOW on Linux while games are rendered in NVIDIA's cloud with Blackwell GPUs, you still need to be using a modern GPU with H.264 or H.265 Vulkan Video support NVIDIA isn't yet supporting Vulkan Video AV1 with GeForce NOW on Linux but just H.264/H.265. If you are using NVIDIA graphics the NVIDIA R580 series or newer is recommended while using the X.Org session. If you are using Intel or AMD Radeon graphics, Mesa 24.2+ is recommended and using the Wayland session. When you are up and running with GeForce NOW on Linux, you have access to over 4,500 games. The free tier of GeForce NOW provides standard access to the gaming servers and limited session caps for an introductory-level experience. It's with the performance tier where you can enjoy RTX ray-tracing and 1440p @ 60 FPS performance and up to six hour sessions. With GeForce NOW's Ultimate tier is where you are running on GeForce RTX 5080 GPU servers with support for up to 5K @ 120 FPS gaming or 1080p @ 360 FPS with up to eight hour gaming sessions in length.

Kernel Community Drafts a Plan For Replacing Linus Torvalds

Linux.Slashdot.org - Wed, 01/28/2026 - 20:25
The Linux kernel community has formalized a continuity plan for the day Linus Torvalds eventually steps aside, defining how the process would work to replace him as the top-level maintainer. ZDNet's Steven Vaughan-Nichols reports: The new "plan for a plan," drafted by longtime kernel contributor Dan Williams, was discussed at the latest Linux Kernel Maintainer Summit in Tokyo, where he introduced it as "an uplifting subject tied to our eventual march toward death." Torvalds added, in our conversation, that "part of the reason it came up this time around was that my previous contract with Linux Foundation ended Q3 last year, and people on the Linux Foundation Technical Advisory Board had been aware of that. Of course, they were also aware that we'd renewed the contract, but it meant that it had been discussed." The plan stops short of naming a single heir. Instead, it creates an explicit process for selecting one or more maintainers to take over the top-level Linux repository in a worst-case or orderly-transition scenario, including convening a conclave to weigh options and maximize long-term project health. One maintainer in Tokyo jokingly suggested that the group, like the conclave that selects a new pope, be locked in a room and that a puff of white smoke be sent out when a decision was reached. The document frames this as a way to protect against the classic "bus factor" problem. That is, what happens to a project if its leader is hit by a bus? Torvalds' central role today means the project currently assumes a bus-factor of one, where a single person's exit could, in theory, destabilize merges and final releases. In practice, as Torvalds and other top maintainers have discussed, the job of top penguin would almost certainly currently go to Greg Kroah-Hartman, the stable-branch Linux kernel maintainer. Responding to the suggestion that the backup replacement would be Greg KH, Torvalds said: "But the thing is, Greg hasn't always been Greg. Before Greg, there was Andrew Morton and Alan Cox. After Greg, there will be Shannon and Steve. The real issue is you have to have a person or a group of people that the development community can trust, and part of trust is fundamentally about having been around for long enough that people know how you work, but long enough does not mean to be 30 years."
