In computing, memoization or memoisation
is an optimization technique used primarily
to speed up computer programs by storing
the results of expensive function calls and  
returning the cached result when the same
inputs occur again.

Speaker Rider

by Tatiana Mac

Last updated 14 April 2021

What is a speaker rider?

As speaking comes with immense privilege, I have crafted a speaker rider to set expectations and boundaries around my engagement. I am grateful to all the conference organisers who have brilliantly hosted me. I would love to continue to exercise this privilege to speak at conferences, and use this privilege to make the landscape more accessible and beneficial to tech's most historically excluded and marginalised communities.

Considerations

😫 I provide a lot of explanations for those of you who never had to consider these things. Most thoughtful conferences I've attended check most of these boxes intrinsically, particularly when conference runners are experienced speakers. They get it.

👀📎 It looks like you're preparing to MC a conference...

🚨 GIANT DISCLAIMER: This stuff is far from authoritative. But it's what I think works for me, and what I enjoy in an MC when I'm attending a conference.

Note:

When this guide is more complete, the plan is to move it into Prepack documentation.
For now I put it out as a gist to gather initial feedback.

A Gentle Introduction to Prepack (Part 1)

If you're building JavaScript apps, you might already be familiar with some tools that compile JavaScript code to equivalent JavaScript code:

• Babel lets you use newer JavaScript language features, and outputs equivalent code that targets older JavaScript engines.

I've gotten a couple of questions about how the RN sync process works, so I thought I'd write up a high level overview of the current process and some of its challenges.

Sources of truth

As far as JavaScript goes, there are a couple of things that live outside of the React Native GitHub repository that get auto-synced in:

• React (core)
• ReactNative renderer
• Other things (e.g. component types like View, Text, the Animated library, StyleSheet, etc.)

The source of truth for React core is GitHub (https://github.com/facebook/react). It gets published to NPM and React Native depends on it via an NPM dependency. e.g. the most recently release of RN (55) depends on React core 16.3.1
