Context

This is for programmers who want to ramp on Go, without resources that reiterate programming fundamentals. This would not be a good list of resources for folks who are learning to program using Go as their first language. Some resources that I dismiss here would be super valuable for newer folks. This is a selection of resources for those who understand programming fundamentals in a different language already.

Advice

1. First steps = Tour of Go
2. Don't waste time on Go Fundamentals-type books - it all lives in tour of Go.
3. Consider joining the Gophers Slack
4. When you need help, the Go Playground allows you make a quick scratch file and share it. Others trying to help can run your code easily this way.

An updated summary on the different ways one could have two contracts interact (DELEGATECALL, STATICCALL, libraries, all that stuff) with clear pros/cons for each (gas cost, whether it requires EVM assembly directives, etc)

Question by /u/drcode

I won't talk about low-level opcodes here because of the brevity of the answer. In general, there are four ways functions can be called in Solidity:

Most VPN Services are Terrible

Short version: I strongly do not recommend using any of these providers. You are, of course, free to use whatever you like. My TL;DR advice: Roll your own and use Algo or Streisand. For messaging & voice, use Signal. For increased anonymity, use Tor for desktop (though recognize that doing so may actually put you at greater risk), and Onion Browser for mobile.
