Good morning,
...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
consultant]...
...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.
Good weekend

Thank you everybody for your responses, I am going to print them out and study them hard, particularly the use of left folds. I think I skipped that in RWH book... .I need to go back and re-cover the basic again I think... it's a tendency of mine to graze through stuff picking up what I need and sometimes you just can't beat learning the basics.
As a still beginner after about eight months of (somewhat intermittent) usage I would say that in order to truly get to grips with Haskell as a concept let alone a language you need to know and understand ...
* currying, which helped me to truly understand the signature notation used, a -> b -> c etc. I have used haXe, which is written in ocaml, and the notation is the same but now makes more sense!
* function composition leading to point-less notation, this is better understood the currying penny has dropped
* lazy versus strict evaluation and the concept of lazy I/O and why it can sometimes leave you scratching your head for a while!! LMAO! :)
* monads: of course, for me the best video I've seen is this one.
As a reluctant Drupal/PHP developer and wannabe FP developer for about six years now, each time I find myself coding some rubbish or other in PHP I have lots of 'ahah!' moments as I think that it would be nice to be able to express some idiom or form more succinctly in PHP and then I realise what X Y or Z is for in Haskell... that's the upside, the downside is I then have to continue the job in PHP!
Thanks again, Sean.
