System Administration: Week 13: Ethics and Social Responsibility (now with AI, oh boy!)

In this week's lecture, we discuss the professional codes of ethics in our field, some hairy ethical dilemmas encountered by #SysAdmins and other engineers, and how we can take an active role in acting in the public interest as part of our jobs.

There are a number of unsurprising parallels to a conference talk I gave way back at Velocity in 2015:

Java TLS has been a blind spot for eBPF-based #observability tools for years. JSSE runs entirely inside the JVM with no exported symbols and nothing to attach to.

Here is how to solve it: https://coroot.com/blog/java-tls-instrumentation-with-ebpf/

Benchmarking our eBPF Java TLS agent against OpenTelemetry, Coroot added only +15% CPU overhead vs +38% from OTEL, which dropped 20% of requests under load.
