In this episode, we talk about HTTP/2, HTTP/3, and QUIC.
Just the Tip
- When copying code from StackExchange, you should first paste it in a plaintext editor (preferably an ASCII-only editor) and then copying from there to strip out nasty unicode. (Or some editors like JetBrains IDEs offer a plaintext paste option, which should be used.)
Starts at 30m22s.
I was drinking Troeg’s Troegenator. Paden was drinking PBR. Jthan was drinking Michelob Ultra.
- HTTP/2, HTTP/3, and QUIC
- Was born from SPDY by Google
- Approximately 97% of browsers in current use support HTTP/2, per Wikipedia.
- Intended to be backwards-compatible with HTTP/1.1.
- Stated design goals:
- Negotiate which HTTP version (or even non-HTTP applications)
- High-level comparability with HTTP/1.1
- Support existing HTTP implementation
- Decrease latency via:
- Data compression if headers
- Server-side push
- Pipelining requests
- HOL (partially/mostly) resolved
- Multiplexing multiple requests over a single TCP connection
- In HTTPS, it requires TLS 1.2 or above with ALPN extension per-spec.
- Interestingly, the spec itself does not require encryption (HTTPS) but the major browsers (Chrome, Firefox, etc.) that support HTTP/2 will only implement it over TLS/HTTPS.
- HTTP/2 has a sort of “alternative” to 301/302 redirection via the “Alternative Service” header…
- But it’s even more flexible than a simple redirect, as it allows things like client-side load-balancing/failover.
- HTTP/3 and QUIC
- Again originally presented by Google (Wikipedia article)
- No longer uses TCP, instead uses QUIC (multiplexed UDP).
- This completely fixes HOL blocking, including the shortcomings that HTTP/2 has with regards to it.
- In the process, multiplexing has been moved lower in the stack/OSI model (in comparison with HTTP/2, which multiplexes client sessions over a single TCP session).
- Both QUIC and HTTP/3 are not a formal RFC yet, but QUIC has a draft.

In this segment, Jthan shares with you a little slice of life. The title is a reference to this video. (2m16s in)

“What type of positions should I seek out to build up my Operations career?”
It depends on what focus you want. If you like working with hardware or want to end up in NetOps, start as a rack monkey for a datacenter. If you’re looking for SysOps, helpdesk/technicians are a good place to start, etc. Jr. SysAdmin is probably going to be your launching point for all of the significant Ops roles, though.
Also look at what your day-to-day will be.
I talk about how apprenticeships should be a much, MUCH more common thing (and be treated as a valid education) for our field.
- I mention the ferrets have (had) “some kind of cold” – we think it might actually have been a reaction to their vaccinations, as it seems to only occur immediately after a round of them (they’ve had another round and the same thing happened since).
- China is indeed buying up a ton of US real estate.
- There are a bunch of stories of people living in someone else’s house without their knowledge
- And yeah, there was a famous case in Japan.
