HN comment orderI think these 3 slides really stand out, they show with how little code one can write serious software in Haskell... 1. ACID (acid-compliant persistance on Haskell data types, with indexes) http://dev.stephendiehl.com/hask/#(27) 2. Pipes (program on streams of data) http://dev.stephendiehl.com/hask/#(30) 3. Scotty (micro web-framework, a la Sinatra or Flask, on top of the super fast Warp server) http://dev.stephendiehl.com/hask/#(32)
Really just learn it. It's a pity I don't use Haskell at work and yet learning Haskell was the single most bang for buck exercise I have ever done. "Parallel and Concurrent Programming in Haskell" is the best resource I have ever read on parallel and concurrent programming concepts. Every programmer should learn this language even if they never plan/get to use it.
One thing that helps alot is the various undergrad course syllabuses that have been given with emphasis on type systems and aspects of FP, immutability, segregating and strictly marking side effects etc. http://shuklan.com/haskell/ http://www.cs.tufts.edu/~kfisher/teaching.html https://www.inf.ed.ac.uk/teaching/courses/inf1/fp/ (P Wadler) http://www.cs.princeton.edu/~dpw/cos441-11/schedule.htm http://blog.davidterei.com/2011/10/stanford-haskell-course.h... http://www.seas.upenn.edu/~cis194/ ________________ also…
What I still do not know and always wished to know when I learned Haskell was how to write efficient code easily. I wrote huge projects with thousands of lines knowing nothing about C++ execution model and had insanely fast code (that could have been made even faster - but I was not that kind of expert) but with Haskell I have to be an expert to really write code that is as performant as something that would take me…
