Has anyone done a study to see if rail is cheaper to maintain than roads? Good public transport infrastructure would go a long way to preserving road conditions and keeping traffic lighter.
I am sure many here have seen this, but this photo seems very informative on the waste of space that is parking lots.
The twelfth annual OpenZFS Developer Summit and first annual OpenZFS User Summit will be an in-person event held in Portland, Oregon, USA Oct 26-29 (Sat-Tue), 2024
After missing BSDCan 2024, we are happy to report a Groff spotting @EuroBSDCon hallway track.
@EuroBSDCon fundraising news: We have a commitment of €500 from community member @openbsdams. This gets us closer to our €2000 goal for hardware: a second ATEM streaming deck plus wireless microphone and accessories needed for EuroBSDCon Dublin. If you can help the make our video efforts it will go toward making EuroBSDCon and future *BSD community videos easier to produce and of higher quality. The first round of hardware donations were used in the main room of BSDCan and the FreeBSD Dev Summit to good results. Boosts welcome.
Discussion is needed on this topic. At one point in the first video they actually talk about the price coming down once they can start mass production. My opinion from the sidelines is that the market for this product is still in the pre-Elon Tesla days when their first roadster was NOT cheap and handmade, and when it was more a proof of concept. Create the product to create the market. I wish them luck.
Upcoming EuroBSDCon OpenBSD talk Confidential Computing with OpenBSD by Hans-Jörg Höxer
Confidential computing is a family of techniques to enhance security
and confidentiality for data in use. One technical approach is strong
isolation for virtual machines.
AMDs Secure Encrypted Virtualization (SEV) offers several feature sets
for isolation of guest virtual machines from an non-trusted host hypervisor
and operating system. These feature sets include memory encryption,
encryption of guest state including CPU registers and an attestation
framework.
In this talk we will explore some of the AMD SEV feature sets. We will
describe how to use them to run OpenBSD as both
Topics covered are CPU feature detection, low level kernel initialization,
memory management, virtio(4) device drivers and the virtual machine
daemon vmd(8).

Upcoming EuroBSDCon OpenBSD talk Building a SD-WAN appliance suitable for an Australian Health Sector NFP/NGO by Jason Tubnor
Latrobe Community Health Service (LCHS) - AS139466 - is a Not for Profit (NFP)/Non-Government Organisation (NGO) headquartered in Victoria, Australia. The organisation consists of 40 offices and 2 data centres across the States of Victoria and New South Wales with over 1,500 employees. All LCHS infrastructure is designed and managed in-house without the use of large-scale cloud infrastructure. Since 2015, BSD Unix has been used for various workloads within the organisation.
This talk focuses on our next generation SD-WAN appliance built on OpenBSD technology using commodity hardware. Topics will include the network topology, design choices, various OpenBSD VPN and routing technologies and orchestrating build, deployment and management across the fleet using Ansible.

Upcoming EuroBSDCon OpenBSD talk A Packet's Journey Through the OpenBSD Network Stack by Alexander Bluhm
When debugging network issues, it is important to understand when
certain things happen. Tcpdump provides valuable insight, pf
transforms packets, pseudo devices add features, and netstat counters
show action. The call graph of the functions within the kernel is
the base to comprehend the relation between these sources of
information.
The layering of kernel code in hardware drivers, pseudo devices,
IP processing, forwarding and protocol layer is explained. The
kernel provides the socket interface to userland processes. Packet
forwarding happens within the kernel. Bridge code uses certain
shortcuts. pf is a swiss knife that can manipulate traffic in
multiple layers. IPsec has an independent interface that overrides
routing. Routing itself and neighbor discovery is a necessary step
that has its tentacles everywhere. Checksum calculation can be
performed by hardware offloading.
By using examples with a single packets, their way through the
kernel is shown. The possible branches, configuration options, and
measurement output are put in correlation.

Upcoming EuroBSDCon talk: Why (and how) we're migrating many of our servers from Linux to the BSDs by Stefano Marinelli
A few years ago, we decided to migrate many of our servers (and many of those of our clients) from Linux to the BSDs - FreeBSD, OpenBSD, NetBSD - depending on the specific services. In this presentation, I will discuss the reasons behind our decision, the technical and organizational challenges we faced, the tangible benefits we have experienced, and why we believe this migration is successful. I will provide specific examples and real-life case studies. In an increasingly complex world, relying on simple, stable, and secure solutions is becoming more and more important, and the BSDs can make a significant contribution in this direction.

Upcoming EuroBSDCon OpenBSD talk OpenBSD vs. IPv6 by Florian Obser
** .ical](https://events.eurobsdcon.org/2024/talk/AV78U9.ics)09-21, 17:45–18:30 (Europe/Dublin), Foyer B **
We will give an overview of past, present and future work on IPv6 in OpenBSD.
We will show how we replaced KAME stack code in both the kernel as well as userland with modern, privilege separated daemons for stateless address auto configuration. slaacd(8) runs on the host to solicit router advertisements and configures addresses and routes. rad(8) runs on the router to send router advertisements. A newly written daemon for DHCPv6, dhcp6leased(8), requests prefixes from an upstream ISP which then can be used by rad(8) for router advertisements.
Next we will show the new IPv6 source address selection in the kernel, including support for the infamous Rule 5.5 of RFC 6724.
In ongoing and future work we will touch on client-side address translation using pf(4)'s af-to feature to support the 464XLAT transition mechanism for v6-mostly networks.
Upcoming EuroBSDCon OpenBSD talk Global anycast using OpenBSD on a budget by Rob Keizer
This talk goes over using OpenBSD as the basis for a highly available globally distributed public anycast network. Distributed decision systems corosync, consul, and raft (using Elixir) are discussed, as are highly available distributed storage and routing systems, all on OpenBSD, all on a budget.
Upcoming EuroBSDCon OpenBSD talk Why rewrite fw_update(8)? By Andrew Hewus Fresh
OpenBSD provides the fw_update(8) utility to handle installing firmware for hardware from manufacturers whose licensing isn't compatible with our base system. We will take a trip into the history of fw_update(8), its structure and why it exists. A recent rewrite provides an illustration of the value OpenBSD places on simplicity and user experience.
Tickets are still available and this talk will be streamed and recorded for later release.
