It's interesting you bring up those talks because that's part of the reason why I'm actually doing this. I'm in a downtime between school and finding work, so I figured why not learn something in the meantime. I'm doing something productive. I've also looked into learning a new language (speaking) to fill in the gap between this time and keep my mind occupied.
I've watched like a billion talks about stuff like this, I really enjoy them and it helps me feel productive!
UPDATE: I will probably be moving on to more complicated matters, like something beyond "Hello world" but I can't figure out what to do yet. Any suggestions?I've tried a few codecademy courses; I don't think I can remember anything without looking it up lol
Perhaps you should try something a bit more complex than "hello world" in each language? A simple app?
