What about demonstrating the use of an Haskell interpreter as a pimped up
calculator?
multTable = putStr $ unlines [unlines [show x ++ ' ':show y ++ ' ':show
(x*y)|y<-[1..10]] | x<-[1..10]]
2007/4/16, Simon Peyton-Jones <[EMAIL PROTECTED]>:
Friends
I have agreed to give a 3-hr tutorial on Haskell at the Open Source
Convention 2007
http://conferences.oreillynet.com/os2007/
I'm quite excited about this: it is a great opportunity to expose Haskell
to a bunch of smart folk, many of whom won't know much about Haskell. My
guess is that they'll be Linux/Perl/Ruby types, and they'll be practitioners
rather than pointy-headed academics.
One possibility is to do a tutorial along the lines of "here's how to
reverse a list", "here's what a type is" etc; you know the kind of
thing. But instead, I'd prefer to show them programs that they might
consider *useful* rather than cute, and introduce the language along the
way, as it were.
So this message is to ask you for your advice. Many of you are exactly
the kind of folk that come to OSCON --- except that you know Haskell. So
help me out:
Suggest concrete examples of programs that are
* small
* useful
* demonstrate Haskell's power
* preferably something that might be a bit
tricky in another language
For example, a possible unifying theme would be this:
http://haskell.org/haskellwiki/Simple_unix_tools
Another might be Don's cpu-scaling example
http://cgi.cse.unsw.edu.au/~dons/blog/2007/03/10
But there must be lots of others. For example, there are lots in the blog
entries that Don collects for the Haskell Weekly Newsletter. But I'd like
to use you as a filter: tell me your favourites, the examples you find
compelling. (It doesn't have to be *your* program... a URL to a great blog
entry is just fine.) Of course I'll give credit to the author.
Remember, the goal is _not_ "explain monads". It's "Haskell is a great
way to Get The Job Done".
Thanks!
Simon
