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.
NOTE: This is a question I found on StackOverflow which I’ve archived here, because the answer is so effing phenomenal.
If you are not into long explanations, see [Paolo Bergantino’s answer][2].
You have a repository, call it alice/repo
. You would like to transfer it to the user bob
, so it will become bob/repo
.
However, you make heavy use of the GitHub Pages feature, so that people are often accessing https://alice.github.io/repo/
. GitHub will helpfully redirect all of your repository stuff hosted on github.com after the move, but will not redirect the GitHub Pages hosted on github.io.
tree-sitter
. This will be enabled by default quite soon now. It is theoretically faster and more powerful than regex based grammars (the one described in this guide), but requires a steeper learning curve. My understanding is that regex based grammars will still be supported however (at least until version 2), so this guide can still be useful.
To enable it yourself, go to Settings -> Core and check Use Tree Sitter Parsers

In case anyone else wants to play with Zig on webassembly, here's what you need to do to make it work on a mac today.
You'll need LLVM to output to the WASM target. This has just been added by default in trunk, so if LLVM >7 is available, you might be able to just brew install llvm
.
If you have wasm support already you should see:
$ llc --version
