Ask HN: Practical project ideas for exploring Go

I've discovered GoLang for myself around 2 years ago when the company I was working for was going to use it, so I had to learn it in a brute-force learning by doing way. I've learnt a lot along the way by looking at existing projects, documentation, writing various tooling in Go. etc.

Recently I've been working with lots of projects involving gRPC, Protobuf and I really enjoy doing that.

Now, I would like to take it to the next step and do a (maybe just small) project that could be of use for others. So far, I was thinking about a MUC-style low-latency audio streaming solution (for jamming online) using gRPC for signalling, TURN for dealing with NAT issues and Ogg Opus as a low-latency audio codec.

I'm very curious about your ideas and now to approach it.
