Hyperactive: HTTP/2 and Python

The internet has spoken, HTTP is to get its first serious update in 15 years. In this talk we'll discuss what HTTP/2 is, why it's happening, and how it's going to affect you and everyone you love. We'll briefly talk about how you can get started with HTTP/2, and some interesting projects associated with it, including Hyper, the first Python HTTP/2 library.

8. HTTP/1.1 is Inefficient
9. HTTP/1.1 is Slowing Us Down
10. HTTP/2
11. Binary • Text protocols are easy to debug but complex to parse • Binary is simpler. • Simpler (usually) means faster
12. Efficient • Multiplexing (with priority/flow control) • Header compression (HPACK) • Early stream termination. • Server Push
13. Not universally well received
14. Poul-Henning Kamp • “HTTP/2.0 is not a technical masterpiece…I would flunk students in my (hypothetical) protocol design class if they submitted it.”
16. Imperfect
17. HTTP/2 is Imperfect • Difficult to reason about • Challenging to debug • Awkward edge cases • Inherently concurrent
18. Bloody Good!
