Hello, I'm somewhat in the SDF community already, even though I rarely come up on COM or BBOARD. I'm a developer by day and I am generally very interested in anything relating to programming, AI, cognitive science, and I've recently taken some interest on bare metal programming, SoCs and RISC-V stuff.
You'll also see me involved in some stuff relating to Plan 9 and, more recently also, Golang programming for Plan 9 on ARM.
Looking forward to participating in SDF activities on Lemmy as well!
Not really, to be honest -- most of what I learned so far about Golang was from their website's documentation and examples. It is not hard to learn in my opinion, especially if you also know some C (since you come from a PHP background, I assume you could manage Golang with a few tutorials). You should probably take a look at Go by Example to see for yourself.
As for "schools", I won't recommend any simply because the only online courses I was recommended were paid ones, and they also did not seem to be extremely good. Furthermore, they were in Portuguese, which is my mother language.
PS. I was also surprised at how Golang does some trivial stuff like connecting to databases. Did you know every database "connection" in fact works as/can work as a connection pool? You end up writing code as if you're sharing a single connection between threads, but in fact, you're not.
