Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

b4ldr

class fastnetmon (
  Hash $policy_defaults = {}
  Hash $policy_overrides = {}
  Array[Stdlib::IP::Address,1] $networks = [], 
  Array[Stdlib::IP::Address,1] $all_networks = [], 
  Optional[Stdlib::Host] $graphite_host = undef,
) {
  $policy_overrides.each |String $network| {
    $network = slice_network_constants($network['network'], {'desription' => '$network['desrciption']})
    file {"etc/fastnetmodn.d/$network_$network['description'].conf": { ... }

What are some tips/things that you have learned after working remote for the first time that you wish you knew before you began?

I’ve been working remote for 10 years, and spend the 10 previous years in an office. Not sure I know what I wish I knew 10 years ago,

The final part of the EM7455 Linux driver support is going in Linux v4.7 which will be released in a couple of weeks. It will also be backported to the currently maintained stable kernels, so you should eventually get it through Ubuntu kernel updates.

Sorry it took this long. In theory, any MBIM modem should just work with the existing Linux drivers. But it turned out that the EM7455 needed a small delay during initialization, or it would silently fail to work. The "fix" is a single line of code:

Falsehoods programmers believe about addresses

This is an anchor-linked version of the excellent, amazing original opus magnum by Michael Tandy.

An address will start with, or at least include, a building number.

Counterexample: Royal Opera House, Covent Garden, London, WC2E 9DD, United Kingdom.

When there is a building number, it will be all-numeric.

Counterexample: 1A Egmont Road, Middlesbrough, TS4 2HT

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.

• A Turkish translation can be found here, contributed by agyild.
• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
