My summary of https://www.youtube.com/watch?v=IqrwPVtSHZI

TL;DR:

Rails has a library, ActiveSupport, which adds methods to Ruby core classes. One of those methods is String#blank?, which returns a boolean (sometimes I miss this convention in Rust, the ?) if the whole string is whitespace or not. It looks like this: https://github.com/rails/rails/blob/b3eac823006eb6a346f88793aabef28a6d4f928c/activesupport/lib/active_support/core_ext/object/blank.rb#L99-L117

It's pretty slow. So Discourse (which you may know from {users,internals}.rust-lang.org) uses the fast_blank gem, which provides this method via a C implementation instead. It looks like this: https://github.com/SamSaffron/fast_blank/blob/master/ext/fast_blank/fast_blank.c

For fun, Yehuda tried to re-write fast_blank in Rust. Which looks like this:

Thank you for extending an invitation to speak at HighLoad++. I
sincerely appreciate your consideration.

I am an outspoken advocate for LGBTQ equality; this position is deeply
woven into my work. Clojure From The Ground Up is adamantly
LGBT-inclusive. Jepsen is named after a gay pop anthem and includes
dozens of references to same-sex relationships and trans identities. My
talk slides are populated with bearded nuns, genderqueer punks, and
trans hackers. My twitter feed is about as gay as it is possible to get.

// Have some complicated non-React widgets that manipulate DOM?
// Do they manage a list of DOM elements? Here's how to wrap it
// into a React component so you can "constantly rerender" it.

// A dumb non-react widget that manually manage some DOM node that
// represent a list of items
function NonReactWidget(node) {
  this.node = node;
}

When a beginner asks you "when do I use semi-colons?" would you rather say this?

// what people who say "use semicolons!!" say
class Foo {
  prop = {
  }; // yes
