- January 31th, 2017: For today's #haskell problem we look at #ephemeris data (double-precision triples) for EMbary (Earth/Moon) and Mars. We parse some big-Ds (double-precision numbers) to get Earth and Mars orbital #ephemeris data from the JPL.
- January 30th, 2017: This week we'll be looking at JPL Earth and Mars Ephemeris data sets. Today's #haskell problem reads in Julian dates. Today's solution uses Prolog Definite Clause Grammars (DCGs) - in #haskell - to read the date string.
- January 27th, 2017: Today's #haskell problem is a little word-guessing puzzle. Today's #haskell solution is another puzzle: To which band do witches band? Will we ever know?
- January 26th, 2017: Today's Haskell exercise tally the word-frequency of a file, so: tally-ho! Today's #haskell solution shows me 'County' is the most popular word in #haskell?!? but okay.
- January 25th, 2017: For today's #haskell exercise, we see what Haskell files are in a directory, eh? Today's #haskell solution to find the Haskell files in a directory structure got me all Monad-y down low on the IO!
- January 20th, 2017: For Today's #haskell problem we look at Merkle Trees of the #blockchain as Traversable.
- January 19th, 2017: Lastly, today's #haskell problem looks at the Traversable function: lastest via @Jose_A_Alonso @yoeight. Today's #haskell solution shows the First shall be the lastest
- January 18th, 2017: As sum is already defined for Traversibles, today's #haskell problem looks at average via @Jose_A_Alonso @yoeight. For today's #haskell solution we find the average of the elements of any Traversable type
- January 17th, 2017: Today's #haskell problem continues Traversable exploration by @Jose_A_Alonso @yoeight with minAF and maxAF...in O(1). So, we have today's #haskell solution for minAF, minT, maxAF, and maxT. lolneat!
- 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!
