Installing Arch Linux with Full Disk Encryption

If you're aiming for a seamless Arch Linux installation in UEFI mode, follow along as this guide will walk you through the process step by step. We'll be using LUKS (Linux Unified Key Setup) and LVM (Logical Volume Manager) partitions on LUKS to achieve full disk encryption.

Note: I have updated this doc for UEFI mode. For those with BIOS/MBR systems, you can refer to the previous version, but keep in mind that it might be outdated and no longer accurate.

If you're only interested in installing Linux and not setting up dual boot with Windows, feel free to skip the Windows-related sections.

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.
