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.

Upcoming EuroBSDCon talk: vmd's multi-process device emulation: 2 releases later by Dave Voutila

** .ical09-21, 14:45–15:30 (Europe/Dublin), Foyer B **

In OpenBSD 7.4, the native hypervisor, vmd(8)became the only open source type-2 hypervisor to default to using a multi-process, privilege separated model for emulating block and network devices.

This talk provides a look at the inspiration from Oracle's contributions to QEMU as a means of multi-layered defense, a review of the challenges and changes required to OpenBSD across 7.4 and 7.5, and a look at the road ahead.

Upcoming OpenBSD talk: Puffy does Realtime Hypermedia by Patrick Marchand

Modern web development is intrinsically tied to javascript and frameworks have been pushing us further and further away from the initial model of the internet as a web of documents. In response to this, libraries like htmx and data-star have arisen to demonstrate ways to use hypermedia to create interactive applications.

Hypermedia as the engine of application state (HATEOS) is a driving principle of these new libraries and by allowing the backend to drive the state of the frontend directly without requiring the user to write javascript code, they make it possible to do hypermedia on whatever you like (Otherwise known as the HOWL stack). 

That means that with nothing but the OpenBSD base install and a small javascript shim (12kb at the time of writing), we can write realtime hypermedia applications. We will explore the case of a small web application that monitors the state of it's server and offers real time updates of it's metrics.

Upcoming EuroBSDCan talk: Building a wind speed logger in NetBSD with GPIO by Nicola Mingotti

(https://events.eurobsdcon.org/2024/talk/7RKDFU.ics)09-21, 13:45–14:30 (Europe/Dublin), Foyer A **

We will see how to set up a small ARM computer (RPi3B+ or BeagleBone Black) to be a remote data logger for wind speed. We will be using gpioctl(8) and gpioirq(4) to collect data. The main objective of the talk is to show how to use gpios to interact with the world that lives outside the computer.

Upcoming EuroBSDCon NetBSD talk: Flipping Bits: Memory Errors in the Machine By Taylor R Campbell

(https://events.eurobsdcon.org/2024/talk/EHTVPK.ics)09-21, 11:45–12:30 (Europe/Dublin), Foyer A **

We've all heard stories of the dreaded cosmic ray angrily flipping bits
in your RAM. But how much does it matter, really? And, more
importantly, how do you tell?

This talk will cover an overview of hardware architecture around
detecting and correcting memory errors, software support for handling
them and other types of hardware errors, and stories of memory errors
in the real world.

And, if the stars align, perhaps we'll have a live demo.
