April 2017 1HaskellADay Problems and Solutions

• April 26th, 2017: Today we do SCIENCE! (ballistic physics, actually) with #haskell. 
• April 25th, 2017: "MOM! MOM! NO BOOK!" Today's #haskell problem: help little Johnny or little Jane's mom find the book! Today's #haskell solution solves mom + mom + no == book, where k == 9 in the blink of an eye with SCIENCE! 
• April 21st, 2017: Today's #haskell problem analyzes @wikidata when it has very poor data-quality and -quantity. #Alaska
• April 19th, 2017: Today's #haskell problem looks at autom(agic)ally generating a SPARQL eye-color query. Today's solution gives EyeColors reified to #haskell values from a @wikidata SPARQL query 
• April 18th, 2017: Today's #haskell problem takes on the HUGE task of automating writing simple SPARQL queries. Today's #haskell solution presents a simple, well-typed @wikidata SPARQL query builder. 
• April 17th, 2017: We look at US States and their Capitals as SPARQLwikidata.org query for today's #haskell problem. For today's #haskell solution we had to drill down into depth of #wikidata resulting JSON to get our State Capitals. 
  
• April 14th, 2017: Today's #haskell problem we make our first foray (again) into the world of @wikidata. What color are your eyes? We get our results back as JSON from our wikidata.org SPARQL query for today's #haskell solution.
 
• April 13th, 2017: For today's #haskell problem we have a little multiplication puzzle. Today's #haskell solution is 'Prolog-escque.' What would your approach be? Oh, and function-composition with (<*>) 
• April 12th, 2017: Today's #haskell problem is a little word puzzle via the Mensa Genius Quiz-a-Day Book by Dr. Abbie Salny. Today's #haskell solution finds you looking rather smart, I must say! 
  
• April 7th, 2017: You're decorating for Spring so you need to write a constraint solver because you're in #Mensa for today's #haskell. tfw you write all these generate and test functions and replace them with a simple filter application #haskell
• April 6th, 2017: Today's #haskell problem is (kinda) based on the OS upon which all other OS's bow down before: FORTH. Fight me. And today #haskell solution we find a use for the </> operator.
• April 5th, 2017: Today's #haskell problem looks at the rise of #bitcoin prices over the past year. Today's #haskell solution runs investment scenarios over a year of historical #bitcoin price data
