Installing powerline on Mac OSX. The following was done in version Version 10.8.2

sudo easy_install pip

Add powerline bin to your path. In your zshrc file (or the paths files sourced in zshrc) add the following line

PATH="/usr/local/share/python/:$PATH"

Reinstall MacVim with brew

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

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.
