Hey @Bugsy6912, thanks for the advice. The metal detector is a good one. I will order now, before try all those different offered to me (BTW, @Secrets, those looks great).
About web development I'll focus on HTML, CSS and JavaScript (mostly frontend technologies as they are called), but also do some backend as python, NodeJS, PHP and so on. Actually I moved to Japan for work, as a new office was opening of the company I'm working for. There is a lot of great opportunities in the programming world, so feel free to ask me anything Bugsy.
