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:**

###
**December 2016**

- December 9th, 2016: Today is #FF on @1HaskellADay. I mean, that's today's #haskell exercise: Examine Twitter JSON for #FF-analytics.
- December 8th, 2016: Today's #haskell exercise comes to you all the way from Smyrna! Construct a word-square.

- December 6th, 2016: Today's #haskell exercise will look at EMA/Exponential Moving Averages to analyze trends of, e.g. #BitCoin. Today's #haskell solution inlines state into the EMA-recursive function to analyze #BitCoin price history.

- December 5th, 2016: Today's #haskell exercise we look at the SMA/Simple Moving Average as a trend-estimator for, e.g.: #BitCoin price. Today's #haskell solution uses the SMA-function as a Comonad. Below are 1 year and 3 months of #BitCoin SMA-analyses.

CORRECTION! SMA 15 and SMA 50 are industry norms in the markets. Corrected (and generalized) #haskell solution here.

- December 1st, 2016: For today's #haskell exercise we look at a larger data set with a year's worth of BitCoin price history.
I love the #haskell standard library. I love that you can write today's solution: #BitCoin prices in one line of code.

"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.
