Hi, I'm mcpower. I've done Advent of Code seriously for two years now in Python, placing 9th in 2018 and 12th in 2017. This year, I'm taking a break from aiming for the leaderboard - while it's fun and all, it is a bit stressful at times (the good kind of stress, though!). As such, I'd like to share a few tips for anyone wanting to aim for the leaderboard.

This is everything that worked for me. Your mileage may vary, though - don't take this as gospel, see what works for you.

You'll need

• Raspberry Pi 3, 3+ or 2 (only)
• A Linux PC, laptop or Raspberry with SD card reader/slot
• A number of Raspberry Pis configured with Ethernet

You must have an SSH key, if you don't know what this is then type in ssh-keygen and follow the instructions.

Prepare to provision RPis:

import (
	"context"
	"flag"
	"fmt"
	"log"
	"net/http"
	"os"

I'm taking down this post. I just posted this as a side comment to explain a sentence on my latest blog post. This wasn't meant to be #1 on HN to start a huge war on functional programming... The thoughts are not well formed enough to have a huge audience. Sorry for all the people reading this. And please, don't dig through the history...

Notes moved from graph-gophers/graphql-go#15

Graphql-js can parse directives like @live just fine -

parsed.definitions[0].selectionSet.selections[0].selectionSet.selections[0].directives[0] =
{ kind: 'Directive',
  name: { kind: 'Name', value: 'live', loc: { start: 26, end: 30 } },
  arguments: [],
 loc: { start: 25, end: 30 } }

Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.
