Meditating over Gustavo Niemeyers http://geohash.org http://geohash.org, I wanted a conversion service * without being stalked after, * headache-free self-hostable, * no runtime dependencies at all, * no javascript whatsoever, * no server-side templating, * purely functional server, * redundant source hosting (both mainstream & indie), so I helped myself. Thanks for reading and I'd really appreciate feedback.
