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.

**Problems:**

###
**January 2017**

- January 16th, 2017: Today's #haskell problem looks at find, any, and all as functions over Traversable types via @Jose_A_Alonso @yoeight. Today's #haskell solution not only defines anyAF and allAF but also the important gtfo, that is: find (> 5)-function.
- January 13th, 2017: Today's #haskell problem does 2 things: examines Applicative Functors (AF) and lets me say transpose...AF in a tweet. Today's #haskell solution shows a succinct applicative solution to transposeAF for matrices
- January 12th, 2017: Partial functions everywhere via @Jose_A_Alonso @bitemyapp! Today's #haskell exercise takes on maximum and minimum. We 'full-i-tize' the partial functions of minimal and maximal for all Foldable t in today's #haskell solution
- January 11th, 2017: Today's #haskell exercise handles the next pitfall from @Jose_A_Alonso @bitemyapp: Prelude partial functions, particularly for the evil List! Today's #haskell solution TOTALly unpartializes some Prelude list functions ... geddit? TOTALly? GEDDIT?
- January 10th, 2017: Continuing #haskell pitfalls review via @Jose_A_Alonso @bitemyapp we study Data.Text to process large text documents. Today's #haskell solution shows Dickens was ahead of his time, citing URLs in
*Christmas Carol*LIKE A WEB GANGSTA! - Side note: I had no problem processing 200k size text document using String, but, hey: knock yourselves out with Text for text processing.
- January 9th, 2017: For today's #haskell exercise we take a leaf from @bitemyapp via @Jose_A_Alonso and look into Data.Aeson quasiquotes. Using Data.Aeson.QQ today's #haskell solution basically wrote itself.
- January 6th, 2017: Today we look at combined US State SAIPE/poverty and debt data, rescale those data, and cluster the results #Haskell
- January 5th, 2017: For today's #haskell exercise we combine US State SAIPE/poverty data along with US State total and per capita debt. Today's #haskell solution on SAIPE/poverty data and US State debts has CHARTS! Never. Underestimate. Charts. 👌💯💯💯
- January 4th, 2017: Today's #haskell exercise we re-look SAIPE/poverty data, reorganizing by US State instead of by US County. We collate US State SAIPE/poverty data, then do a bit of analysis with a pensé about results thrown in at the end.
- January 2nd, 2017: For the beginning of AD 2017, today's #haskell exercise wishes you a less divisive year than the last. LITERALLY!

"Clone in IDE" just takes me to FP Complete's 404 page. Is there still a free IDE for working Haskell A Day problems? What? Where?

Thanks.

My answer: I use vi, simply inserting the copied text into the editor and working on the code off-line.
