By Yanis • Issue #91 • View online

It’s been a looooong week.

I have been starting seriously learning ElasticSearch, and this book is of a great help when you already know the basics! It’s not free, but it is worth every dollar.

R&M

I finally watched the last episode of Rick And Morty. I have mixed feelings. It was fun, but I kinda expected something grander for an episode that “explains everything.” I don’t want to spoil it for you, so I’ll stop here.
