[$] MOT: a tool to fight openwashing in AI
Many large language models (LLMs) are described as open source, but if one looks a bit deeper it turns out that is not actually so; the model may be free to download, it may be " open weight ", but it does not fit the Open Source Initiative (OSI) Open Source Definition (OSD). Assessing the actual openness of models is not easy, as Arnaud Le Hors explained in his talk about the Model Openness Tool (MOT) at Open Source Summit North America 2026. The tool is designed to help users of LLMs understand to what degree a model is (or is not) open, and to combat the openwashing that is prevalent with LLMs.
Andrew Morton's 2004 OLS keynote
I recently presented a brief tribute to Andrew Morton at the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit ; it included a suggestion that reading (or re-reading) his 2004 Ottawa Linux Symposium keynote would be instructive. This talk, given immediately after the Kernel Summit session that decided to fundamentally change the kernel's development model, tells a lot about how the kernel project got to where it is today. The text of that speech was hosted on Groklaw, and has since been replaced by crypto spam, which is rather less useful. In the hopes of preserving this seminal moment, the transcript has been rescued from the Wayback Machine and is presented here.
Canonical’s Workshop: sandboxed, reproducible dev environments
Canonical has released Workshop, a new open-source tool to create reproducible development environments from a single YAML configuration file. The same setup can be reproduced across different hardware and devices, it reduces dependency issues and configuration drift within teams. Environments in Workshop are built from SDKs (packages that install languages, frameworks and tools). Most of these come from the SDK Store, which supports versioned channels similar to the Snap Store so that projects can define specific SDK versions to use. Canonical offers SDKs for Ollama, OpenCode, NVIDIA CUDA and AMD ROCm at launch, but users can create and define project-specific […] You're reading Canonical’s Workshop: sandboxed, reproducible dev environments , a blog post from OMG!

Cache Aware Scheduling Shows Nice Wins For AMD Zen 5 On PostgreSQL, Valkey, Network Performance
The long-in-development work on Cache Aware Scheduling looks like it will come to a head soon with it looking like Cache Aware Scheduling will land for Linux 7.2. Ahead of the upcoming merge window I ran some fresh benchmarks looking at different areas where this feature is shining.
[$] Further progress toward removing the page map count
The mapcount field was created to track the number of mappings (page-table entries) that refer to the given page. Among other things, a mapcount of zero means that the page has no references and can be reclaimed. Maintaining mapcount has become increasingly challenging and expensive as the memory-management system has grown in complexity, so Hildenbrand has been looking for ways to get rid of it. This session was, he said, maybe one of the last times he will have to bring up this topic.

Linux Developers Looking At Retiring The x32 ABI
The Linux x32 ABI for x86_64 processors allow making use of the full 64-bit register file and wide data path but retaining 32-bit pointers to provide for a smaller memory footprint when not needing 64-bit pointers. Linux x32 came to the party late and didn't enjoy much adoption over the years and is now looking at possible removal from the Linux kernel...

Arias: Human proof for FOSS contributions
Rodrigo Arias Mallo, maintainer of the Dillo web browser, has written a blog post with a proposal on one way to ensure that a contribution is written by a human and not AI; he suggests asking new contributors to record their programming session using asciinema. In the same way that LLMs generate patches, they can also generate the asciinema recordings themselves. Then, the contributors can lie to the reviewers pretending to have made the edits. Perhaps surprisingly, this is not a easy task for LLMs, at least from my observations. The corpus of recordings of developers making mistakes and thinking the whole process of editing a file is not as large as the corpus of FOSS programs and patches in which to train an LLM. During my very simple tests I haven't been able to generate an asciinema session that remotely resembles what I would expect from a human, and even less so from a human with a nice editor theme and editing an existing Dillo source file. The Dillo project is not yet requiring asciinema recordings, but he said that he would like to test the theory further. LWN covered asciinema in January 2026.
Raspberry Pi 6 won’t arrive before 2028 – and is skipping an NPU
The Raspberry Pi 6 won’t be released before 2028 and won’t feature an onboard NPU to handle AI compute when it does. Insight into their plans for the Pi 6 and when it’ll arrive were shared by three of the company’s key engineers and leaders in an AMA (ask me anything) session on Reddit on 21 May, 2026. Based on past launches the gap between major Pi models (Raspberry Pi 2, 3, 4 and 5) is around 3-4 years. The Raspberry Pi 5 launched in 2023. That should put the Pi 6 on course for launch in 2026 or 2027. […] You're reading Raspberry Pi 6 won’t arrive before 2028 – and is skipping an NPU, a blog post from OMG! Ubuntu.

NVIDIA Vera CPU Benchmarks: Olympus Cores Delivering The Best Performance Ever Seen On ARM
NVIDIA's Vera data center CPU isn't ramping up until later this year but I recently had the opportunity to try out this new ARM-based CPU designed for agentic AI workloads. NVIDIA's Vera CPU with its in-house-designed Olympus CPU cores ends up packing a heavy-hitting punch with competitiveness to Intel/AMD x86_64 CPUs that I have never seen out of any other ARM or non-x86_64 processors. Continue on with these early benchmarks of the NVIDIA Vera CPU on Linux.

Stenberg: The pressure
Curl maintainer Daniel Stenberg writes about the stress of keeping up with the current flood of security reports. This is a never-before seen or experienced pressure on the curl project and its security team members. An avalanche of high priority work that trumps all other things in the project that is primarily mental because we certainly could ignore them all if we wanted, but we feel a responsibility, we have a conscience and we are proud about our work. We feel obliged to fix security problems in the software we have helped shipped to every device on the globe. This is personal to us. With about half the release cycle left until the pending release ships, we already have twelve confirmed vulnerabilities meaning twelve pending CVE announcements. That's a new project record and it also means we will reach thirty published CVEs in 2026 even before half the calendar year has passed. The projected total amount of curl CVEs published through the whole year is therefore at least double this number!
