Hi
I am trying to build a web application using Yesod and sqllite. Can anyone please refer me to some working example of similar application? Something like https://www.fpcomplete.com/user/twoolie/yesod-learning-through-doing/simple-guestbook but that actually compiles?

I want to learn Haskell but still have some problems on using recursion. On simple tasks I can make it work but for example the tower of Hanoi I cannot figure out how things are can be solved.

Is there a book or tutorial with exercises so I can pratice it

Hi,
i'm new to haskell and still learning. Can anybody help me with anonymous functions aka lambdas?

The function ifNext parses one input character without remove them from imput. It matches against cond if its true works goes on with thenParser otherwise elseParser .

ifNext :: (Char -> Bool) -> Parser out -> Parser out -> Parser out
ifNext cond thenParser elseParser = if (\x -> cond x ) then thenParser else elseParser

But it does not match the type. Can anyone explain why?

The expression between "if" and "then" needs to be either True or False, but your lambda expression is of type "Char -> Bool". You will need to supply a Char value to that expression as in "(\x -> cond x) value" or simply "cond value".

1. did you succeed with deploying your app to ec2?
     - yes i use Keter (https://github.com/snoyberg/keter)
2. Also, can you maybe to refer me to some fpcomplete tutorial on using Yesod with DB support
    - Maybe this would help:
       > https://www.fpcomplete.com/school/advanced-haskell/persistent-in-detail/existing-database        > https://www.fpcomplete.com/school/starting-with-haskell/libraries-and-frameworks/persistent-db

3.  https://www.fpcomplete.com/user/twoolie/yesod-learning-through-doing/simple-guestbook      - Maybe this is out to date, by the look at it i was publish almost a year and a half.

also you can try this: http://www.yesodweb.com/book it was refered by +Michael Snoyman .

cheers :)

https://www.fpcomplete.com/wp-content/uploads/Bump-case-study.pdf - does anyone know how haskell was used to scale up to 250 cores as mentioned in that case study? I'm interested in any links to relevant papers or links to libraries or any extensions that they might have used.
