So, my favourite language is Python, and for web developing I use Pyramid, and to stay in my "comfort zone" I use brython for client scripting, don't take me wrong, I love javascript, but for just a bit of performance lost I like being able to use all my pre-existing python code if I need to...
So, this was my first work experience, for a military industry, we had to make a service for uploading big files and sending them via email.
I heard one thing that shot me out of my "comfort zone" (I'll call it cf from now on)... "Use php"...
So, I already had written in php and I've always disliked it, perl-ish and broken as a bethesda game (i like bethesda games, but they are broken)
Another thing: javascript vanilla or jquery, never liked jquery either, so I decided to use vanilla js...
So, after 6 months of work, my partner and I finished it...
Well, more than one year later that mess we had to make to satisfy our boss' most absurd desires is not online yet, I search it on google every month, so yeah, 6 months of my life wasted (also, it was a "stage", so not only I didn't get any recognition, but they didn't give me any money)
