The Ying-Yang of CEOs and Engineers

All successful startups begin with two founders. One guy is the Engineer, and the other guy is the business dude. Over the years of working with various people, I've learned what makes a good engineer, and what makes a good business dude, and the two are complete opposites of each other.

You need to run the build.sh to build the server and start it with ./server 0.0.0.0 3000 1 server.key server.crt. Assuming you've generated server.key and server.crt. If not, follow the instructions on http://www.akadia.com/services/ssh_test_certificate.html.

Once you've the server started, you can either use curl (with http2 support) or run the client with go run client.go. If you want to see debug logs of the underlying http2 implementation, run it as GODEBUG=http2debug=2 go run client.go.
