How to create a 1280x1080 (among others) scaled resolutions for your non-standard monitor

Ultrawide monitors with PBP (Picture by Picture) are becoming more common these days. It allows you to split the screen and connect multiple sources to your monitor (e.g. 2 computers at the same time)

The problem is that the resolution is typically not supported out of the box (E.g. a 2560x1080 monitor, when split into 2 will require a 1280x1080 resolution, which is not standard in Mac OS as of Sierra)

Creating custom resolutions

First, we have to reboot in rootless mode, and disable the Integrity Protection, so we can create/override the screen file settings:

Type-safe Redux reducers in TypeScript using Immutable.js and typed-immutable-record

We attempt to harness the friendly API of Immutable.js to build Redux reducers while trying to preserve as much type safety as possible.

State branches are TypedRecords. A combineReducers that outputs TypedRecords is provided.

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.~~
