No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.
Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

- There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

There are three easy to make mistakes in go. I present them here in the way they are often found in the wild, not in the way that is easiest to understand.
All three of these mistakes have been made in Kubernetes code, getting past code review at least once each that I know of.
- Loop variables are scoped outside the loop.
What do these lines do? Make predictions and then scroll down.
func print(pi *int) { fmt.Println(*pi) }
