This is just a dump of some interesting undocumented features of webOS (3.8 specifically, on early 2018 4k LG TV) and other development-related tips.

Homebrew app ideas

• OpenVPN frontend (OpenVPN itself is easily buildable and runs on webOS TVs: https://discord.com/channels/407937994037919756/835489130967859251/906943542457401395)
• App autostart manager - dynamically update arbitrary app config and register it as input (see Registering an app as an input)
• webos-vncserver frontend with autostart option
• Package hyperiond into Piccap directly
• Quick Screenshot (expose HTTP port that just returns PNG of current screen contents)
• Custom IR remote codes editor/updater/blaster

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.

// This works on all devices/browsers, and uses IndexedDBShim as a final fallback 
var indexedDB = window.indexedDB || window.mozIndexedDB || window.webkitIndexedDB || window.msIndexedDB || window.shimIndexedDB;

// Open (or create) the database
var open = indexedDB.open("MyDatabase", 1);

// Create the schema
open.onupgradeneeded = function() {
    var db = open.result;
    var store = db.createObjectStore("MyObjectStore", {keyPath: "id"});

# My steps to:
# Convert DVD Video to MPEG-4 in MKV without GUI, using only CLI (Command Line Interface) tools.
# No need for MeGUI, Avisynth, Handbrake etc..
# ------------------------------------------------------------------------------

# Tools needed: `mediainfo`, `ffmpeg` & `ffprobe`, `x264`, `mkvmerge`, `mplayer` (optional).
# Google for them. Use latest versions. Windows tip: avoid Cygwin and get
# the official builds, x64, when possible.

# Before start use `mediainfo` & `ffprobe` and note down informations about the source material:

UPDATE: You don't need shims anymore! We can just use this now, and eventually it'll even be in Ember core.

app.import() works with node_modules now! As of Ember 2.15. Previously it only worked with bower_components and vendor.

Docs for app.import are here: https://ember-cli.com/managing-dependencies#standard-non-amd-asset
