**August, 2014**

- August 1st, 2014: "But programming isn't math, so ..." Today's #haskell problem? 'Fix' yesterday's solution to be less ... 'icky.' http://lpaste.net/108559 π, fast (So you're not eating π? ... okay: 'quickly.') A solution set to today's exercises with Wow-o-wow results. http://lpaste.net/108576
__Bonus__: August 1st, 2014: This is Embarrassing(ly parallel) to have π in da face! http://lpaste.net/108562- A-to-the-ST for da D-down-low-on-the-SL. Today's #haskell exercise is write your own language, then some rules. Yeah. http://lpaste.net/108733. LAWLZ! NAND on the A-to-the-ST! http://lpaste.net/108758 A solution to the first 2 exercises to today's problem. YMMV: not pretty nor generic.
- Baby needs a new pair of shoes! And you need a new daily #haskell problem to solve. http://lpaste.net/108820 Done! ;) Love is the Universal Language. No, wait. We were talking about Money, yes? Me confused. Solution to today's exercise http://lpaste.net/108829. I have a Yen for Thinking Japanese, or so I think so ... a solution to the bonus #haskell exercise http://lpaste.net/108871
- Bayes was a man of letters. A Bayesian classifier for letter-recognition? Sure, let's give it a go for today's #haskell exercise. http://lpaste.net/108901 So now we know 'M' looks like 'W' to some peeps but 'B', 'I', 'O' check out fine, so WE ARE READING WITH HASKELL! YAY http://lpaste.net/108916 ... added definitions to do test runs over the entire data set and then did various runs, tweaking the system. Results noted. Informative.
- Today's #haskell exercise. An expert system for blood donation. I use the term 'expert' loosely, eh? ;) http://lpaste.net/108989 Have at it! "I vant to drinq yur bloot! Bwa-hahaha!" Okay. That quote is just ... creepy. A solution to today's exercise is at http://lpaste.net/108994
- Veni, Vidi, ... Duci? http://lpaste.net/109043 Today's #haskell exercise. It is a relief to know that no tactical nukes were launched by testing the solution to today's #haskell exercise. http://lpaste.net/109061 or How do you count Mississippi's in Roman numerals?
- August 11th, 2014, Monday: You've heard of 'Rock Management'? How about ROCK LOBSTERS! GIVE ME A ROCK, NAOW!!!1!!!!11! Today's #haskell exercise http://lpaste.net/109188
- August 12th, 2014, Tuesday: To Fract or Not to Fract: why are we even considering this question? Today's #haskell exercise http://lpaste.net/109219

- Ooh! Bonus problem? On a Tuesday? Wowsers! Today's #haskell #bonus problem: "Continuum spectrum maximum... uh, 'thing'um" http://lpaste.net/109205
- August 13th, 2014, Wednesday. No problem! (literally), but: "Fract! The Cylons!" No... wait: Starbuck used a different word. A solution to yesterday's fracting problem is at http://lpaste.net/109341

Flatliners. No fracting, no 'peak'ing, just a baseline data set of

initializeSpectrum defined with flatline function.

Twin Peaks. Still not fracted, but data set with two spikes

rolled into the base data set with smoothSpike fn

Fracted. Data set with peaks, fracted using the frackedSpike function

- August 14th, 2014, Thursday: Pining for that next fibo date-time before 2584. Today's #haskell problem inspired by @AlgebraFact http://lpaste.net/109349. Updated problem. Tightened up return value, removing unnecessary semideterminism. So, it gives, leik, a septatuple answer, leik. ... Yeah. Time keeps flowing like a (Fibonacci) river, to the sea. http://lpaste.net/109389 A solution to the 'next Fibonacci' problem posted today.
- Hail, Eris! or the Law of Fives or today's #haskell problem (implementing a Ripple-down rule set). Do it to it! http://lpaste.net/109350. One of three-parter solution to today's problem: Forall Existential(ism) http://lpaste.net/109458 A solution allowing forall-quantified values. Two of the three-part solution: All you need is fnord (la-di-da-di-dah)! Rippling down (and accumulating fired) rules http://lpaste.net/109433. Third of three-part solution: RippleDownRuleto ergo sum, adding rules to the RDR system http://lpaste.net/109473. Updated the 3rd solution to the RDR (Writer monad definition) to ripple down to left and right, fixing inconsistency in rule findings.
- August 18th, 2014: What's FP good for? Crypto and technical (financial) indicators. Why? Um, let's do today's #haskell exercise! http://lpaste.net/109553. Full on, all the way! Double Rain-... wait: line-graph. Solution to today's #haskell exercise http://lpaste.net/109597

- August 19th, 2014: What does it all mean? All the way! No, wait: this is just today's #haskell exercise (backtesting SMA indicator ). http://lpaste.net/109617 Take the monoid and run(State-WriterT), or WAAH! WAAH! I lost 100 corn chips on my investment strategy or, solution: http://lpaste.net/109687 But, as solace, it does come with a pretty picture, illustrating today's solution. Ooh!

- August 20th, 2014: Next up for today's #haskell exercise is the Exponential Moving Average. http://lpaste.net/109689 A solution to the E(xponential)M(oving)A(verage) #haskell problem: Stately Conformance http://lpaste.net/109707

- August 21st, 2014: My Jeans. No ... I meant: 'GENES'! That's it. Today's #haskell exercise. http://lpaste.net/109749 A solution to (not even CLOSE to) 'yesterday's' #haskell exercise: Nature or Nurture? We present a genetic algorithm http://lpaste.net/110330
- August 22nd, 2014: Today's (much delayed) #haskell problem: the Silver Ratio http://lpaste.net/109817 (from @AlgebraFact ) Every cloud has a silver lining .. Every Haskell problem has a solution. (sometimes) (except noncomputable problems) http://lpaste.net/109831

- August 25th, 2014: LYADCFGG! Today's #haskell exercise? (automated/learned) Document classification. http://lpaste.net/109980/
- August 26th, 2014: "Join me, Luke, on the Dark Side of the Force, and help me go #FORTH to solve today's #haskell exercise! MWA-HAHA!" http://lpaste.net/110062 The World's smallest DSL: Forth. A solution to today's #haskell exercise http://lpaste.net/edit/110085
- August 28th, 2014: "As I compose this #haskell problem ... p.s. I love you ... You! You! You!" #1960s #song http://lpaste.net/110135 A little card logic problem. Oh, NOES! LOOK OUT! IT'S A CARD-#SHARKNADO! Nah, it's just 'today's #haskell solution, is all http://lpaste.net/110334

- August 29th, 2014: Groovitudes! WordNet Themes! or: today's #haskell exercise http://lpaste.net/110171 A 3x3 matrix has 36 possible solutions. A 5x5 matrix? Over 200M poss solutions? YIKES! A solution to the themed-words http://lpaste.net/110293

**Notes**

- The Forth language problem solution given on August 26th gives a very snazzy RPN ('reverse Polish notation') calculator, but that's all it does the ':'-defining word needs access and look-ahead to the program parsed stream, and that's a bit more to ask than pushing and popping stack operators.
- For the August 29th problem(WordNet themes) the raw generated solution set is over 209M possibilities. My little Haskell program was not finished scanning them over four hours when I killed the process. However, my dear wife solved the problem in under five minutes. Setting aside the fact that she's a genius, the program needs to be better. It needs to use the ontology of English-language words to eliminate fruitless endeavors during their generation, not afterwards during the test phase.

Great stuff, I hope you continue with these.
