Announcing a 10-Week Graduate-Style Seminar on OS Trade-Offs for Engineers
https://www.reddit.com/r/programming/comments/1nzwu3b/announcing_a_10week_graduatestyle_seminar_on_os/

<!-- SC_OFF -->Hi everyone, The Tock Foundation / Better Bytes (the non-profit behind the Tock operating system) is launching a new virtual graduate-style seminar for practicing engineers, and we wanted to share it with this community. Title: Operating System Trade-Offs: Performance, Extensibility, and Security Description: The course is a 10-week deep dive into the fundamental trade-offs in systems design. The goal is to help engineers become better systems builders and researchers by identifying and analyzing these trade-offs through a curated list of foundational and modern papers. Instructor: It's led by Dr. Amit Levy, a well-known researcher in the OS community. Format: This is designed for a professional schedule. It’s a weekly 1-hour live discussion (Tuesdays, 11am-12pm PT) based on 1-2 papers. The seminar runs from Oct 21 to Dec 23, 2025. Audience: It's intended for SWEs with a background in systems programming. The cost is $2,000 USD, and proceeds support our non-profit's mission. We know this is a significant cost, and it's structured to be a good fit for company professional development/education budgets. You can find all the details on the landing page here: https://betterbytes.org/courses/seminars/ I'm one of the organizers and am happy to answer any questions you might have. <!-- SC_ON --> submitted by /u/exobrain (https://www.reddit.com/user/exobrain)
