Migrating from SSHFS to NFS

First of all, this is not a tutorial, this is more like a lab notebook of my experience trying to ditch sshfs and start using NFS. The main problem I had with sshfs is that it is not very reliable as a file system to remain mounted 24/7. For example, I had some problems unmounting it when it got stuck in a machine, creating lots of zombie processes.

Since 5 years ago, my CV is written using LaTeX, using (and modifying) the Awesome CV template. On top of that, I added a few things to make it bilingual, compiling either in Spanish or English, making the document available in multiple languages....

How to create a "Work in progress" banner for your website

My personal website is currently made in Symfony. Yeah, I know, not the best thing for this purpose, but I started it a few years ago, when I was younger and carelessler… A few days ago, I decided I wanted to refactor my website and create a whole new one, using a static site generator. Ended up deciding on Hugo, btw. As the old one was a bit, well, clunky, I wanted the new one to be online ASAP as possible....
