# Two things are important to note: 
#
# 1) The code is fugly, because it was a JavaScript/iPad experiment. 
#    I know that it is ugly, so pretty please don't comment on that part.
# 2) I tried to use as many CoffeeScript features as possible,
#    including but not limited to list comprehensions,
#    heredocs, destructuring assignment and also the "do" operator
#
# I welcome comments about stuff that is not CoffeeScripty enough, or what I should
# write differently.

GeoPlanet data with ancestor chain cache imported in 10 minutes

Yahoo! provides its GeoPlanet data as three separate TSV files, available for download here.

That's a database with some 17 million records:

• 5.7 million records: locations (aka places).
• 2.2 million records: alternative names for each place (aka aliases).
• 9.6 million records: matrix of neighbourhoods per place (aka adjacencies).

My summary of https://www.youtube.com/watch?v=IqrwPVtSHZI

TL;DR:

Rails has a library, ActiveSupport, which adds methods to Ruby core classes. One of those methods is String#blank?, which returns a boolean (sometimes I miss this convention in Rust, the ?) if the whole string is whitespace or not. It looks like this: https://github.com/rails/rails/blob/b3eac823006eb6a346f88793aabef28a6d4f928c/activesupport/lib/active_support/core_ext/object/blank.rb#L99-L117

It's pretty slow. So Discourse (which you may know from {users,internals}.rust-lang.org) uses the fast_blank gem, which provides this method via a C implementation instead. It looks like this: https://github.com/SamSaffron/fast_blank/blob/master/ext/fast_blank/fast_blank.c

For fun, Yehuda tried to re-write fast_blank in Rust. Which looks like this:
