Some Old Posts about Haskell

In the last weekend, I moved some old posts about Haskell. Here is a list.

• Why Monoid Everywhere
• What are Functors
• What are Applicative Functors
• Rewrite foldl in foldr, Explained: This post was supposed to appear in SDU Lambda, but I didn't publish it there for some reasons. I also fixed some minor errors in this post.
• Create New Types in Haskell
• Bottom Type in Haskell

There are some older posts about functional programming in the old WordPress database dump. But they are too rudimentary. So I don't want to move them to here.
