[$] Free software needs free tools

One of the contradictions of the modern open-source movement is that projects which respect user freedoms often rely on proprietary tools that do not: communities often turn to non-free software for code hosting, communication, and more. At Configuration Management Camp (CfgMgmtCamp) 2026, Jan Ainali spoke about the need for open-source projects to adopt open tools; he hoped to persuade new and mature projects to switch to open alternatives, even if just one tool, to reduce their dependencies on tech giants and support community-driven infrastructure.

Garrett: To update blobs or not to update blobs

Matthew Garrett examines the factors that go into the decision about whether to install a firmware update or not. I trust my CPU vendor. I don't trust my CPU vendor because I want to, I trust my CPU vendor because I have no choice. I don't think it's likely that my CPU vendor has designed a CPU that identifies when I'm generating cryptographic keys and biases the RNG output so my keys are significantly weaker than they look, but it's not literally impossible. I generate keys on it anyway, because what choice do I have? At some point I will buy a new laptop because Electron will no longer fit in 32GB of RAM and I will have to make the same affirmation of trust, because the alternative is that I just don't have a computer.

Intel Rendering Toolkit & OpenVINO AI GPU Performance On Intel Panther Lake's Xe3 B390

Over the past month I have been running a lot of Linux benchmarks on Intel's new Panther Lake using the Core Ultra X7 358H and its Xe3-based Arc B390 Graphics. The Arc B390 on Linux has been quite interesting with its OpenGL and Vulkan graphics performance compared to prior generations of Intel graphics plus the Intel Compute Runtime / OpenCL performance too. In today's article are more benchmarks of the latter in looking at the Intel Rendering Toolkit and OpenVINO AI performance on the Xe3 B390 Panther Lake graphics compared to prior Lunar Lake and Meteor Lake.

Intel Adapting Linux's LAM In Preparing For ChkTag

Last year AMD and Intel as part of the x86 Ecosystem Advisory Group announced ChkTag for x86 memory tagging across processors to better fight buffer overflows and use-after-free errors. In preparing for ChkTag with future processors, Intel has begun adapting their Linear Address Masking (LAM) support to more nicely jive with it...
