Gruber: Have you seen this thing where there's this group that wants to turn Markdown into an IETF standard?

Marco: No, w-- let me guess -- Jeff Atwood?

Gruber: I don't even know, you know what, it broke last weekend. I was out of town with Amy and wasn't paying attention, and I've been busy this week on other stuff. I haven't even paid attention to it. I don't know if it's associated with Atwood's crusade or not. And, there's talk from some people -- and the funny thing is, they're doing it on a mailing list that I still host and I haven't participated on in years. And I don't know why I haven't pulled the plug on the damn mailing list, but I still host the markdown-discuss mailing list, and there's people saying that they should just take the name Markdown from me because I've been such a lousy steward of it and whatever. Meanwhile, you know, there's the web pages on my site for Markdown describing the syntax and everything are more popular every single day. It's more popular -- I could actually -- I've t

Fun with vector maps

A goofy slippy map of various vector tile data sources. With some fun colours, greetz to Aaron and Mike and Mike and the whole Prettymaps crew.

Sacramento, CA • SF bay area, CA • New Orleans, LA • Boulder, CO •

Quickie D3-only slippy map of rivers.

Completely cargo-cult hacked from mbostock's OSM vector tile demo

Say you have a bunch of things, like thousands of photos from your digital camera. What if you wanted to look at them all at once? A typical user interface might order the photos chronologically by column and then by row, which does a decent job of grouping related photos together... But, if you have thousands of photos, the rows may be hundreds of photos long, and it is impossible to zoom in on a group of related photos!

An alternative that better preserves locality is a space-filling curve, such as the Hilbert curve. These curves can be used to place related things next to each other in space, avoiding those huge gaps across rows you see with sequential layout.

This example demonstrates the effect of using a Hilbert curve for layout with Polymaps by generating rainbow-colored tiles. As you can see, each tile is surrounded by its adjacent colors in the rainbow, even as you zoom in and ou
