Comments from the author over at Wolfram Community: http://community.wolfram.com/groups/-/m/t/138400#_19_message... I hope he has found a job by now!

I wish he would apply for a job with us. I don't see any contact details, otherwise I would ask him directly.

I was thinking the same thing. Best I could find was the developer email listed for his calculator app: https://play.google.com/store/apps/details?id=com.projectfan...

[Edit] Which makes me realize that the submitter for the original was him: https://news.ycombinator.com/user?id=pr_fancycorn - so that may lead to some way to contact him.

Ah, thank you!

And I understand more and more of it each time it gets submitted which is very satisfying.

This really is a magical resource. I've just spent ~45 minutes browsing then looked at the scrollbar to notice I'm not even 1/4 down the page yet.
