Bri Hatch is Director of IT at ExtraHop Networks, and Chief Hacker at Onsight, Inc.

He's been doing SRE and devops long before they had a name. He believes that SLAs are a good thing, only pages and tickets are actionable (NOT EMAIL!), graphs are for capacity planning, and logs are for troubleshooting or to be shunned entirely.

Bri is mainly a Python head these days, having shed the last remnants of Perl with the exception of his decades of dotfiles history. One day he'll get into Golang, but C will always be his first love.

Bri has taught security, Unix, and programming classes for corporations through Onsight and as an adjunct instructor Northwestern University. He has been securing and breaking into systems since before he traded in his Apple II+ for his first Unix system.

HTTP, first defined in 1991, has undergone radical change since it was created by Tim Berners-Lee in the days of dialup. We'll cover the notable problems and improvements from 0.9 up to the proposed HTTP/3 which sheds TCP entirely and implements a secure and highly performant TLS-over-UDP protocol known as QUIC.

No prior knowledge of HTTP or networking is required, but even those comfortable writing web requests at the command line will learn a thing or two.
