Your source for diverse discussions from around the Go community. This show records LIVE every Tuesday at 3pm US Eastern. Join the Golang community and chat with us during the show in the #gotimefm channel of Gophers slack. Panelists include Mat Ryer, Jon Calhoun, Carmen Andoh, Johnny Boursiquot, Angelica Hill, Mark Bates, Kris Brandow, and Natalie Pistunovich. We discuss cloud infrastructure, distributed systems, microservices, Kubernetes, Docker… oh and also Go! Some people search for GoTime or GoTimeFM and can’t find the show, so now the strings GoTime and GoTimeFM are in our description too.
Don't forget about memory management
Bryan Boreham (Grafana Labs) and Jordan Lewis (Cockroach Labs) join Mat and Jon to talk about memory management in Go. We learn about the heap, the stack, and the garbage collector. There are also some absolute gems of wisdom scattered throughout this episode, don’t miss it.

Jordan says:
It’s complicated because it still doesn’t work out of the box, you need my branch which isn’t merged:
- https://github.com/jordanlewis/debug/tree/fix-bugs… (my branch)
- https://github.com/golang/debug/tree/master/cmd/viewcore… (the upstream)
- https://go-review.googlesource.com/c/debug/+/321736… (the CL that isn’t merged yet)
