...hang in there, it's a long learning curve...I too am trying to figure out
if you can make money with Haskell or F#...[I'm an independent software
...I picked up a copy of "Category Theory" by Steve Awodey - it supposedly
is geared to Computer Scientists and not Mathemeticians - but I couldn't
understand it and my math is pretty good
[...and I've had 4 years of college math]
...btw: did you neglect to include the link for 'monad:...the best video
I've seen is this one' - could you please provide it.
