Florian Obser (florian@) recently gave a BSD-NL talk entitled "Let's find out how to get predictable IPv6 addresses assigned to OpenBSD VMs".
Florian takes us on a guided tour of how inet6 autoconf actually works, with enlightening and entertaining peeks into selected piece of OpenBSD source.
At the end, we are asked to "now, draw the rest of the owl".

Since 2026/04/20, I cant receive anymore the feed rss!
It's down?
The URL I've: https://undeadly.org/cgi?action=rss
I cant access to the website too.
(for my 100Th post, I request about undeadly… ‽)
OK, today, we've news about this! Due to hardware failure, the machine hosting undeadly has gone down last week. Thanks to the kind and swift help from OpenBSD.amsterdam, we're now back online. We will source new hardware for the original machine and hopefully move back again soon. https://undeadly.org/cgi?action=article;sid=20260511202034 PS : The show must go-in on… -
We’re releasing a brand new, open-source mouse design: the Bean, which is a pointing stick mouse (also called a nub mouse).
(…)
As with all of our other kits, the Bean is 3D-printed and fully open-source.
Mechanical files, electrical files, and firmware have all been released, along with documentation on how to make and modify your own. It’s all on Github!

The purpose of this post is to summarise the various details regarding upcoming changes, improvements and new features in Linux 7.1.
See:
⇒ Linux 7.1 Lands ARM64 NEON-Accelerated CRC64-NVMe For ~6x Improvement:
Descr: Merged 13/04 were all the CRC code updates for the Linux 7.1 kernel. Most notable with that pull is an ARM64-optimized CRC64-NVMe implementation that can deliver multiple times faster performance...⇒ Linux 7.1 Revamps T10 PI Data Integrity Handling For Better Read Performance:
Descr: Merged 13/04 for the Linux 7.1 kernel is overhauling the T10 PI code for generating and verifying data integrity information. In turn the new code is cleaner while also allowing for better read storage performance...⇒ Linus Torvalds Rejects Performance Fix "Hack" & Kconfig "Terrible Things" For Linux 7.1:
Descr: While a lot of interesting new features and changes have been merged already for the Linux 7.1 merge window, two pull requests stand out so far for being rejected by Linus Torvalds and complete with his to-the-point commentary...⇒ LLM-Assisted Patches For Linux 7.1 May Have Negative Impact On 32-bit Systems:
Descr: Code now merged for the Linux 7.1 kernel may provide some negative performance implications for those still running modern Linux kernels on 32-bit hardware. A fundamental change can present cache line alignment and slab sizing implications for 32-bit Linux OS users but will provide for cleaner code with modern 64-bit computing...⇒ Linus Torvalds Merged The Code Beginning To Remove Intel 486 CPU Support In Linux 7.1:
Descr: As a follow-up to the news first-covered on Phoronix earlier this month about Linux 7.1 expected to begin removing i486 CPU support: it indeed happened. Linus Torvalds took the initial removal bits today without any fuss today for beginning the phase out of M486 / M486SX / ELAN kernel support...⇒ exFAT For Linux 7.1 Helps Reduce File Fragmentation, Fixes:
Descr: The exFAT file-system changes have landed for the in-development Linux 7.1 kernel...⇒ Linux 7.1 Gets Rid Of Some Unnecessary Memory Clobbers:
Descr: The x86/asm changes merged yesterday for the Linux 7.1 kernel with a few low-level improvements...⇒ AMD EDAC Driver In Linux 7.1 Adds Support For Zen 3 Rembrandt Hardware With ECC:
Descr: The Error Detection And Correction "EDAC" subsystem updates have been merged for Linux 7.1 that deal with reporting of ECC memory errors and the like from various hardware drivers...⇒ Linux 7.1 Adds New Child Auto-Reap & PIDFD Auto-Kill Flags For clone3():
Descr: The clone3() system call in Linux 7.1 is adding three new flags for greater control over the creation of child processes...

In the world of open source, trust is our most valuable currency. ONAP is a “collection of individual, semi-standalone network automation functions that provide design, orchestration, observability, and automation of network and edge services for operators, cloud providers, and enterprises” (per ONAP). When we build software that powers global telecommunications, “good enough” isn’t an option…

⇒ Open Infrastructure is Not Free: A Joint Statement on Sustainable Stewardship (2025/09/23)
An Open Letter from the Stewards of Public Open Source Infrastructure
Over the past two decades, open source has revolutionized the way software is developed. Every modern application, whether written in Java, JavaScript, Python, Rust, PHP, or beyond, depends on public package registries like Maven Central, PyPI, crates.io, Packagist and open-vsx to retrieve, share, and validate dependencies. These registries have become foundational digital infrastructure – not just for open source, but for the global software supply chain…⇒ Open Infrastructure Is Not Free, Part II: The Hidden Cost of Running Package Registries (2026/05/06)
The September 2025 Working Together Towards Sustainable Open Source open letter raised the alarm about the economic sustainability of open source package registries, highlighting how rising adoption and the pace of innovation are placing new and growing pressures on open source package registries. Those pressures have only accelerated in the time since the letter, amplified by the adoption of AI coding agents and tools…

On OpenBSD forum, Over the past few weeks, I've created several posts whose titles begin with ‘OpenBSD Stories’, about Miod Vallat's articles…
Today I’m thinking to myself, I should have "posted in the same topic"!
Is there a way to group them together?

Hello bsd.cafe users!
I wanted to show y'all my desktop. I thought we could start a chain of people posting their desktop setups on their machines running any of the *BSDs
I'll start. This is OpenBSD with StumpWM. Shown is emacs on the left, DeaDBeeF on the top right playing "chipmunks on 16 speed", and xterm on the bottom right. The "bar" is StumpWM's built in modeline.
