There's an issue reported in ruby-pg (ged/ruby-pg#325) where a query hangs and never return results to the application.
This adapter extension controls it with a ruby timeout set to 5 seconds. If the query doesn't return results in 5 seconds it aborts the async_exec method and tries the exec one.
We're not proud of this vut it saved a lot of erratic errors.

Esta lista es el primer paso en mi proceso de deshacerme de libros.
Quien me conoce sabe lo mucho que me importan mis libros y lo que me duele separarme de ellos.
Algunos me han gustado, otros los he abandonado (perdona, Paul Auster). Todos me han hecho como soy, y creo que es hora de que se vayan a otros hogares a formar a otras personas.
Si has llegado aquí y quieres alguno de los libros, soy @brenes en Twitter.

This is my best try at transcribing of the lightning talk I gave at RUG::B on April 2016. Due to poor time management (LOL) the delivery was rushed and some examples were skipped, I hope having them posted here makes them more useful.
xargs is a small but very useful program that is installed in most if not all of your computers¹. Many of you probably know it. Those who don't will learn something really useful, but those who do will learn a couple of cool tricks, too.
You might have heard about the Unix philosophy:
