Mastodon frontend perf suggestions

I took some time this weekend to analyze Mastodon's frontend performance. I didn't manage to write many fixes (just a config fix and better caching for static assets) so this was mostly just investigation.

The point of this document is to lay out some of my initial thoughts, since it may be helpful for others. There's a lot of technical jargon, so you may want to get some background by looking at my blog post on "The cost of small modules" and my talk on "Solving the web performance crisis" (slides).

How to install dlib v19.9 or newer (w/ python bindings) from github on macOS and Ubuntu

Pre-reqs:

Have Python 3 installed. On macOS, this could be installed from homebrew or even via standard Python 3.6 downloaded installer from https://www.python.org/download. On Linux, just use your package manager.
On macOS:
- Install XCode from the Mac App Store (or install the XCode command line utils).
- Have homebrew installed
On Linux:

Update: download the new Pokemon Go app - it fixes all of this. Download it, and reauth, and you should be set. The grant scopes and prompt are correct and visible now too! Now if only I could actually find a pikachu...

Pokemon tokens are requested with these understandable scopes:

openid
email
https://www.googleapis.com/auth/userinfo.email
https://www.google.com/accounts/OAuthLogin (this scope does much more than it appears. see update on the bottom for more info)

	A simple example pyside app that demonstrates dragging and dropping
	of files onto a GUI.

	- This app allows dragging and dropping of an image file
	that this then displayed in the GUI
	- Alternatively an image can be loaded using the button
	- This app includes a workaround for using pyside for dragging and dropping
