Guix: Unifying provisioning, deployment, and management in the age of containers
This talk will reflect on what GNU Guix has to offer to users and how it compares to other approaches—from CONDA and pip to Flatpak and Docker.

We encounter a lot of organizations talking about or attempting to implement SRE as part of our consulting at Real Kinetic.

Notes from Facebook's Developer Infrastructure at Scale F8 Talk
Any time Facebook talks about technical matters I tend to listen. They have a track record of demonstrating engineering leadership in several spaces.

This sounds like it would be a problem, but in fact that change didn't bother FreeBSD at all: Now that everything uses hardware-based paging…
