Ask HN: Best of 2014

It's the end of the year and that means a lot of best of 2014 articles are popping up all across the internet. Since many of these are probably only of interest to a minority of HN readers and thus won't appear on the front page I thought we could use this thread to collect the interesting ones that we've come across.

My favorite so far is this one at Marginal Revolution: http://marginalrevolution.com/marginalrevolution/2014/12/top-ten-mr-posts-of-2014.html

I'm also excited to see what Michael O. Church will be posting in the upcoming year: http://michaelochurch.wordpress.com/2014/12/29/2015/
