My first experiment with NodeJS was on August 2012: I wrote a prototype of a multiplayer game with Socket.io and I was amazed by its power and simplicity. Also, npm was a step forward at that time in the world of package management. Nowadays I still appreciate this concept: using one language for backend and frontend. Few years later there was a quantum leap in the JavaScript ecosystem, the language evolved and the transition was handled in the best way (IMO). In general, I consider JavaScript the lingua franca of IT: if I write an algorithm in JavaScript almost any developer can read it and translate it in any other language.

I like the concept of reproducibility: I did few experiments with Docker. It is a great tool, but sincerely I still use more Amazon AMIs.
- fake-aws-redshift
- is a docker image with a PostgreSQL 8.0.2, i.e. compatible with AWS Redshift
I am addicted to CLIs and the shell. I wrote few tools and my opinion is that a bash script is still the cheapest and fastest way to automate a task.

Probably Golang is not the definitive language, but, for me is perfect. First of all, a compiled language was missing in my reportoire. Deploying or distribute a single executable is a big win. I also like the simplicity of the language: yes, only 25 keywords actually attract me. I really like the fact that it handles concurrency and it is multicore out of the box: it relaxes me, I can focus only on the algorithm... but I confess that, as a mathematician, I felt in love with Golang cause it has builtin complex number data type. Wow!

When I started working in IT in 2005 my boss said: you need to learn Perl. Big respect for the camel, I learned a lot from this language and its community. It is still my preferred language for string manipulation and parsing.
