1HaskellADay: Up, up, and away!

I've taken it upon myself to submit problems, then show the solutions, for @1HaskellADay. I started this work on July 1st, 2014. So the next set of entries serve to collect what I've done, both problems and solutions, and, if a particular day posed a particularly interesting problem, that I solved, or, that I didn't solve, I'll capture that here, too.


Now thanks to Go/Haskell by Example, we're returning to basics for our daily Haskell problems.

Well, yes, perhaps, but Big Data... can Haskell be a player here? Let's find out, shall we?

One-liners moved to haskell-one-liners tab.

October 2015

  • October 6th, 2015: So YESTERDAY we looked at Foldable. @argumatronic said "Step it up: do Traversable!" So for TODAY'S #haskell problem http://lpaste.net/4868288594713772032 So we WuTang Traversible CLANNED that solution! http://lpaste.net/4953464088320540672
  • October 5th, 2015: For today's #haskell problem we go from Monadical to Foldable, thanks to @argumatronic http://lpaste.net/2602721740102565888 Wait. Is 'monadical' a word? DList. Foldable instance. Done. http://lpaste.net/8044707151110733824
  • October 2nd, 2015: For today's #haskell problem we make multimaps fast with difference lists ... OR. DO. WE! http://lpaste.net/8174150842572603392 And today we find out HOW FAST MULTIMAPS ARE WITH DLISTS! (in all caps, no less) http://lpaste.net/341094126416035840
  • October 1st, 2015: Yesterday we made Difference Lists Applicative, for today's #haskell problem we make them monadic http://lpaste.net/1062399498271064064 So, difference lists are monadic now ... so there's that ... http://lpaste.net/4828960021565931520
