/**
 * XXX: Okay, so, no date library, other than moment, appears to currently

 * date string `2018-11-21T15:00:00+0100` (UTC+1:00), I want to format it as
 * `3:00 PM`, regardless of the system's current local time.
 *
 * This seems like it should be easy, right? We don't need time zone data,
 * because we're not specifying a time zone, just a UTC offset. All we need to

Random thoughts on sets

Sets can be generalized as a function that takes an argument and returns true or false.

Sets of numbers

For a specific set of numbers, you can write it as:

const mySetOfNumbers = num => [1,2,3,4,5].includes(num);

React recently introduced an experimental profiler API. This page gives instructions on how to use this API in a production release of your app.

React DOM automatically supports profiling in development mode for v16.5+, but since profiling adds some small additional overhead it is opt-in for production mode. This gist explains how to opt-in.

gif-from-tweet

There are so many great GIFs out there and I want to have copies of them. Twitter makes that harder than it should be by converting them to MP4 and not providing access to the source material. To make it easier, I made a bash pipeline that takes a tweet URL and a filename, extracts the MP4 from that tweet and uses ffmpeg to convert back to GIF.

Dependencies

• ffmpeg
  • macOS: brew install ffmpeg
  • Ubuntu/Debian: apt install ffmpeg
