They sound like cool projects but your saying "btw, I'm 24" felt like blatantly showing off. Congrats on having achieved so much at a young age! But seems to me like a main objective of the post is to further boost your ego.
Thanks for the feedback. I included it because I've seen similar HN posts mention age (and my birthday was recent, so it was on my mind). I've removed that information so this post stands on its own.
Spent a solid five minutes trying to figure out the issue with choosing "in2013dollars.com" as a name until I realized. (For people, like me, who need more coffee: it's about to be 2014.) I'd imagine implementing an API for this (or even just an endpoint that spits out JSON) would be a similarly good exercise.
Thanks for the post! This is very inspiring. I'm just now learning to code (Mech Egr by education) and it is exciting to see what's possible out there at the side project level. Good luck with Asteroid mining!
