58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

Don't use VPN services.

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) }

The introduction to Reactive Programming you've been missing

	Took me a while to figure this out, this should never be so difficult IMHO. The dynamodb api could use more examples in its doc.

	The documentation for doing this is scattered in a few places:

	1. dynamodb api doc for golang: https://docs.aws.amazon.com/sdk-for-go/api/service/dynamodb/
	2. the Update Expression: https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Expressions.UpdateExpressions.html

	The structs belowed are abbreviated for the sake of the demo: adding a string to the questions slice in the dynamodb table.

	require 'socket'
	require 'base64'

	Refresh = 1 # seconds to refresh image on server
	screen_capture_command = 'screencapture -C -x tmp.png'
	image = ''
	latest = Time.now
	server = TCPServer.new 3000

	grunt.initConfig({
