It seems hard to understand in our eyes, but you have to appreciate the lack of education and superstition in Brazil. If you ever read the famous feedback from Feynman about the standard of teaching in Brazil (shit) then you would know why.
What I love here on HN is that even though everyone here seems to hate on MongoDB, it keeps on rolling, improving, and getting used in real companies. There may be "better" (for spurious defn of better) products like rethink or whatever, but folks just aren't using them. Get over it!
Wow - this story ticks so many tick boxes for HN readers:
1. An important person who can code - for all those who moan that those in power do not understand tech at all.
2. He used C++ - for all the rust-tards and c++ haters
3. He mentions Haskell - for the fp buffs claiming it is the one true way.
