Agenda

⇒ (05/25) /e/OS 4.0 live launch

Join us live on June 11 for the official launch of /e/OS 4.0, the latest evolution of the mobile operating system designed to put people — not Big Tech — back in control of their digital lives. Built around privacy, transparency, and user freedom, /e/OS continues to offer a powerful, user-friendly and ethical solution to mainstream mobile ecosystems.

This two-day summit will be co-located with the 22nd Annual BSDCan, which will run until June 20, 2026, in Ottawa, Canada. The summit will include developer discussion sessions, vendor talks, and working groups. Registration is now open. Please feel free to add yourself and anyone else wishing to attend to the lists below. Note that the developer summit is open to everyone and (unlike some previous years) no invitation is required; but non-developers may not have write access to the wiki.

⇒ (05/25) Linus Torvalds to ‘start being more hardnosed’ about ‘pointless pull requests’ – some of which come from AIs

Linux kernel boss Linus Torvalds has signaled he’ll push back when he receives irrelevant pull requests, after complaining that developers are making badly timed and trivial submissions, sometimes after using AI to review code. Torvalds foreshadowed changes in his weekly state of the kernel update, which on Sunday announced the release of a fifth release candidate for version 7.1 of the Linux kernel.

⇒ (05/25) Let’s Learn Linux: Customize and use the shell environment — Lesson 3/3

Learn how to customize and use the shell environment in Bash — this is lesson 105.1 from the LPIC-1 exam curriculum (102-500).

⇒ (05/26) OpenBSD stories—Some Terrific Idea

In this story, I would like to talk about something which has turned out to be both an asset and a curse.

⇒ (05/27) Proton Experimental gets fixes for Subnautica 2, War Thunder, Far Cry 4 and more

More Linux / SteamOS gaming improvements arrive from Valve with a new update to Proton Experimental. This update landed on May 26th.

⇒ (05/27) Managing Cache and DirectIO for Databases on ZFS

Database workloads behave very differently from traditional file storage, requiring specialized caching and I/O strategies to maintain performance and consistency. This article explores how Direct IO works in OpenZFS, how it interacts with the ARC and database buffer caches, and when bypassing the filesystem cache can improve latency, throughput, and NVMe performance for database workloads.

⇒ (05/27) Connect FreeBSD to OpenBSD using WireGuard

This guide details the step-by-step process of establishing a WireGuard VPN connection where a FreeBSD client initiates a connection to an OpenBSD monitoring server. On the OpenBSD side, the setup involves creating a WireGuard interface, generating keys, and configuring network settings via /etc/hostname.wg0. The FreeBSD configuration requires loading the if_wg kernel module, generating private and preshared keys, and setting up the interface using rc.conf and rc.local for persistence across reboots. The final step involves adding the FreeBSD peer details—including its public key, allowed IPs, and preshared key—to the OpenBSD configuration and restarting the interface. The connection is verified via ping, ensuring secure communication for metrics, logs, and alerts between the servers. The guide assumes OpenBSD 7.9 and FreeBSD 14.4 but notes compatibility with nearby releases.

⇒ (05/28) BSD Now—665: 60 Puffies

OpenBSD 7.9, Critical Infrastructure in FreeBSD, GhostBSD Finance report, Solaris 11.4 updates, and more…

⇒ (05/28) OpenSSF Newsletter – May 2026

What a month! May was packed with milestones for the OpenSSF community, and we’re still riding the high from an incredible OpenSSF Community Day North America in Minneapolis. The community showed up in full force to celebrate some major wins: five new members, the launch of our inaugural Ambassador Program, a brand new AI eBook, the Python Secure Coding Guide, and so much more. A full recap of Community Day is coming soon, so stay tuned. In the meantime, read on to catch up on everything new in May!

⇒ (05/28) Linux 7.2’s Open-Source Nouveau Driver To Finally Support The NVIDIA GA100

Sent out today was the last drm-misc-next pull request ahead of the Linux 7.2 merge window getting underway in June. As part of this last batch of small Direct Rendering Manager graphics/accelerator driver changes is finally enabling the NVIDIA GA100 within the Nouveau driver…

⇒ (05/28) ReactOS brings its Windows NT tribute act to ARM64

ReactOS, the open source project aiming to recreate Windows NT, has reached a new milestone: booting on ARM64. The ReactOS team cautioned that the build was “still in an experimental state,” while encouraging users to try it. Screenshots show the project running on ARM64 (via QEMU) and on a Raspberry Pi 5.

⇒ (05/28) AV2 specification and reference code — v1.0.0

AV2 is the next-generation video coding specification from the Alliance for Open Media (AOMedia). Building on the foundation of AV1, AV2 is engineered to provide superior compression efficiency, enabling high-quality video delivery at significantly lower bitrates. It is optimized for the evolving demands of streaming, broadcasting, and real-time video conferencing.

⇒ (05/29) Aligning on Machine-Readable Signals as the Foundation for Due Diligence

The software supply chain has reached a level of complexity where manual oversight is no longer a viable strategy for security or regulatory compliance. Modern systems depend on vast, rapidly evolving networks of components, making manual, paper-based approaches to due diligence impractical. Machine-readable, continuously generated security signals are therefore the only realistic way to support Cyber Resilience Act (CRA) due diligence at scale. These signals already exist across open source ecosystems as a natural byproduct of standard development practices, though they remain fragmented across tools, repositories, and pipelines. Crucially, these signals are best understood as mechanisms for transparency rather than assurance: they expose observable characteristics of software development and operational behavior without constituting guarantees, certifications, or transfers of liability.

⇒ (05/29) QEMU mulls relaxing AI contribution ban

A key Linux virtualization component, QEMU, is considering relaxing its blanket ban on AI-generated contributions to allow limited assistance from the bots. The suggestion came from Paolo Bonzini, distinguished engineer at Red Hat and a maintainer of the KVM hypervisor. Bonzini’s suggestion is to allow AI assistance “where the ramifications of copyright violations are at least easy to revert and unlikely to spread.

⇒ (05/29) Migrate TrueNAS Core to Sylve

For years I ran TrueNAS Core on my home fileserver. This was an awesome, easy way of running FreeBSD + ZFS + tools without a lot of manual maintenance. Unfortunately TrueNAS decided to start using Linux as the basis of TrueNAS and I love using FreeBSD. Fortunately a new project is on the horizon which looks promising:
