The difference between XYZ and TMS tiles and how to convert between them

Lots of tile-based maps use either the XYZ or TMS scheme. These are the maps that have tiles ending in /0/0/0.png or something. Sometimes if it's a script, it'll look like &z=0&y=0&x=0 instead. Anyway, these are usually maps in Spherical Mercator.

Good examples are OpenStreetMap, Google Maps, MapBox, MapQuest, etc. Lots of maps.

Most of those are in XYZ. The best documentation for that is slippy map tilenames on the OSM Wiki, and Klokan's Tiles a la Google.

A collection of WebGL based protein viewers on the Web.

=======================================================

An increasing number of WebGL based protein viewers are becoming available. Here a collection of all the viewers that I could find so far (sorted alphabetically).

Chromium OS ft. Docker

Chromium OS is cool. Chromium OS with crouton is cooler. Chromium OS with Docker is even cooler. This is specifically a guide for the Chromebook Pixel 2 (2015), but I can't think of any reason it wouldn't work with other devices.

Create a build environment
Customize the kernel
Build Chromium OS
Flash Chromium OS to USB
Install Chromium OS

A non-exhaustive list of WebGL and WebGPU frameworks and libraries. It is mostly for learning purposes as some of the libraries listed are wip/outdated/not maintained anymore.
