A History of the BSD Daemon by Marshall Kirk McKusick

https://youtu.be/SGC0191nDp0

This talk tells the history of the BSD Daemon. It starts with the first renditions in the 1970s of the daemons that help UNIX systems provide services to users. These early daemons were the inspiration for the well-known daemon created by John Lasseter in the early 1980s that became synonymous with BSD as they adorned the covers of the first three editions of `The Design and Implementation of the BSD Operating System' textbooks. The talk will also highlight many of the shirt designs that featured the BSD Daemon.

A distributed filesystem for OpenBSD by Rob Keizer

This talk goes over the development of a distributed filesystem tailored for OpenBSD. While OpenBSD excels in many areas, its native filesystem support has room for improvement. This talk goes into using the Filesystem in Userspace (FUSE) on OpenBSD to provide for a distributed and highly available filesystem.

This talk also includes an introduction to the Raft Consensus Algorithm, which plays a critical role in ensuring data consistency and reliability across distributed systems. The Elixir programming language is used, providing the necessary foundation for the implementation of the distributed FUSE filesystem on OpenBSD.

BSDCan 2025 Keynote: Hardware Support for Memory Hungry Applications by Margo Seltzer

https://youtu.be/OCWaGRcPO8E?feature=shared

For nearly 60 years, we lived in a CPU-centric universe. Today, we are on the brink of a transition -- GPUs are the new golden child and those children demand unprecedented amounts of DRAM to satisfy modern data-hungry applications. I'm going to talk about these hardware trends and what they mean for those of us who build systems.
Speaker bio: Margo Seltzer is Canada 150 Research Chair in Computer Systems and the Cheriton Family chair in Computer Science at the University of British Columbia. Her research interests are in systems, construed quite broadly: systems for capturing and accessing data provenance, file systems, databases, transaction processing systems, storage and analysis of graph-structured data, and systems for constructing optimal and interpretable machine learning models.
She is the author of several widely-used software packages including database and transaction libraries and the 4.4BSD log-structured file system. Dr. Seltzer was a co-founder and CTO of Sleepycat Software, the makers of Berkeley DB, the recipient of the 2021 ACM Software Sytems award and the 2020 ACM SIGMOD Systems Award. She is a past President of the USENIX Assocation and served as the USENIX representative to the Computing Research Association Board of Directors. In 2019 recipient of the USENIX Lifetime Achievement Award.
