Writing an iOS YouTube Music client

I’ve been using YouTube Music as my main music streaming service for almost a year and a half. The iOS client is great- I’ve never had a single complaint. It’s potentially one of the most bug free apps I’ve ever used, it has an extremely friendly, and simple, graphical interface, and the service itself is great.

I was curious how the client worked in terms of networking, and while curiosity may treat cats poorly, it ~~lands researchers in black sites~~ can provide a lot of insight.

Step 0

The first thing I do when reverse engineering a client is monitor HTTP requests while the application starts up, and when doing the tasks interested in. On a jailbroken iOS device, I use FLEX by FlipBoard.

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.

Twitter abuses all media file uploads, each type in its own way. If we want to upload a good looking animation loop from some low-color, high-detail generative art, we have to game their system's mechanisms.

don't upload a video file, they will re-encode it into absolute 💩
create a GIF, which they will auto-convert into a video file 😱
The frames of the GIF will be resized to an even-sized width using an extremely naive algorithm. Your GIF should be an even size (1000, 2000,

Upgrade to at least 0.8.4

Using newer compiler versions and the optimizer gives gas optimizations and additional safety checks for free!

The advantages of versions 0.8.* over <0.8.0 are:

Safemath by default from 0.8.0 (can be more gas efficient than some library based safemath).
Low level inliner from 0.8.2, leads to cheaper runtime gas. Especially relevant when the contract has small functions. For
