What are some good awards for a software development competition?

Budget: $1200

Some context:
We are organizing our flagship event with six tracks - each has its own set of talks and events. For the Software Development track, we are organising a Battlesnake competition and would love to get some ideas about the awards.

P.S. We are giving them general event swags too, but need something relevant to software dev as an addition

P.P.S. Giving money directly is not an option due to some administrative stuff

I just got my first mac and trying to get used to it after coming from Ubuntu. What are some cool tools and utilities you guys use which can make this transition smoother and maybe increase productivity?

P.S. Just downloaded Amethyst and used it for the first time. It is no less than sorcery xD

True story

Okay fine now enough is enough

Yes I declared and assigned the variable after calling the function and it's usage, and yes I copied it directly from a tutorial which had snippets everywhere, and yes I was blind and it took me 4 hours to find this bug, while eating chocolate but that's not important (c'mon I deserve a chocolate) and yes I found it immediately when I was posting a question about it on Stack Overflow.

But please JavaScript, why can't you do some magic find the variable in the whole script?
