Over the years, I made a handful of maps of various things in Cambridge; I have collected some, but not all of them, on this page about housing things in Cambridge.

This includes things like maps of where you could legally build a fourplex (short answer: not many places!); the distribution of tax paid per parcel (Kendall Square pays a lot!) and more.

Fun fact: sharing this link on Mastodon caused my server to serve 112,772,802 bytes of data, in 430 requests, over the 60 seconds after I posted it (>7 r/s). Not because humans wanted them, but because of the LinkFetchWorker, which kicks off 1-60 seconds after Mastodon indexes a post (and possibly before it's ever seen by a human).

Every Mastodon instance fetches and stores their own local copy of my 750kb preview image.

(I was inspired by to look by @jwz's post: mastodon.social/@jwz/109411593.)

Mastodonjwz (@jwz@mastodon.social)Mastodon stampede. "Federation" now apparently means "DDoS yourself." Every time I do a new blog post, within a second I have over a thousand simultaneous hits of that URL on my web server from unique IPs. Load goes over 100, and mariadb stops... https://jwz.org/b/yj6w

@crschmidt well, this sounds like a p0 bug. Mastodon is going into robots.txt on many servers once this gets noticed widely.

@cshabsin Don't worry! I just confirmed that Mastodon doesn't respect robots.txt for any of these fetches, so even if it's added to robots.txt, it will have no effect!
