Was anyone else really into project euler? I was thinking about it today and I'm surprised to find that my old login still works! I used it to learn C++ back in the day. Wow, I was so into this site. I remember sitting in the sun on a quiet bench behind a Goog office in Mountain View solving just... one... more... before going back to project work. Good times.

I started December 2011 and apparently the last one I solved was #133 on August 23 2013.
