I am extremely grateful that Mozilla is providing this opportunity to me; hopefully I can give something back by making some hands-on contributions to the Rust ecosystem.

Today is day 1 of my internship -- at least if you start counting at 0, which of course we all do.
I meant to write this yesterday, but the morning was filled with bureaucratics and in the afternoon I got so jetlagged, I essentially was sleeping with my eyes open.
(But don't tell Aaron, my manager, or Niko, my mentor -- I was of course supposed to be working. ;)
