The best Postgres feature you're not using – CTEs aka WITH clauses
SQL by default isn’t typically friendly to dive into, and especially so if you’re reading someone else’s already created queries. For some reason most people throw out principles we follow in other languages such as commenting and composability just for SQL. I was recently reminded of a key feature in Postgres that…

Dijkstra on Haskell and Java (2001)

How Python 3 Should Have Worked (2012)
As a workaday Python developer, it’s hard to shake the feeling that the Python 2 to 3 transition isn’t working. I get occasional requests to make my libraries work in 3 but it’s far from clear how to and when I try to look it up I find all sorts of conflicting advice, none of which sounds very practical.

How misaligning data can increase performance 12x by reducing cache misses
Here's the graph of a toy benchmark 1 of page-aligned vs. mis-aligned accesses; it shows a ratio of performance between the two at different working set sizes. If this benchmark seems contrived, it actually comes from a real world example of the disastrous performance implications of using nice power of 2 alignment…
