New #Haskell video: some exercises from Set 15 of the #Haskell MOOC, which is all about Squishy Mappables (formerly known by their old, inferior name of "Applicative Functors")

New interview with Kinichi Motegi on YouTube.
The 100% true story of how my dad (accidentally) blew up my Apple //e.
What if I took the chocolate of EmuDevz and mushed it into the peanut butter of Haskell? It turns out it tastes delicious. I talk a bit about my experience building a working NES emulator in Haskell.

It's time to play "Follow the types!"
We look at two "tricky" monad problems from Set 13b of http://haskell.mooc.fi, and do some hole-driven development.

Some final words on our EmuDevz JavaScript emulator, which is finally finished, and then on to the next challenge...writing an NES emulator in Haskell!
If you want to skip the introductory remarks about the JavaScript code and get straight to the Haskell, skip to around 3:45.

New video: "A Wave of Monads"

Thumbnail print: "The Great Wave of Kanagawa", by Hokusai (1831).
In problem set 13b we get more practice with monads. I try to consciously explore my mistakes deeply so people can follow along as I get lost and then find my way.
Monads (or as I like to call them, sequenceables) aren't magic! In Set 13a of the MOOC at haskell.mooc.fi, we get more practice with them.
