GopherCon UK had sort of started the day before (day 0) with a few workshops. I skipped those.
At any given time, it was either a keynote with everyone in a big room, or split into 3 different talks.
Overall, a pretty solid first day.
Saying that you can build off of concrete constraints and not abstract or divergent ideas. Not too interesting
Basic intro into TinyGo with a pracical IoT usecase of temperature/humidity recorder. Fun, because it's something I don't do.
Profile and get rid of memory allocations. Not just the obvious ones, but also through indirect things like interface and slice conversions / wrapping. Also, lift easy things out of loops. Dives into parts of the runtime you usually don't think about, by Bryan Boreham
Can you read go build -x?
Also GODEBUG=gocachehash=1.
Also-toolexec.
Use buf, they make good protobuf tooling.
What is eBPF and how you'd want to use it with Go. Technically I've heard this talk a few times, but Liz Rice is an amazing speaker.
The speakers stuck around for at least a bit, so there were opportunities to talk to them (still want to gush over Liz...). Other than that, day 1 was mostly meeting with people I knew from online: so what appears to be half the CUE team: Daniel Marti, Paul Jolly, Roger Peppe, Marcel van Lohuizen. Also Bill Kennedy and Mat Ryer.
I drank a bit too much and my head hurt.
