2. Day 1

2.1. Production Rules on Databases, Paula Gearon

  • Relationships and Predicate Logic
  • Create a Datalog example with the ontology for Food
  • Axioms:
cuisine(Italian)
food(Pasta)
ingredient(Flour)
ingredient(Milk)
ingredient(Egg)
  • Rules application as an edge between data nodes
  • Rete

The Rete algorithm [72,56] was originally conceived by Charles L. Forgy in 1974 as an optimized algorithm for inference engines of rule based expert systems.

lein run --jason data/in.json --out data/out.json data/family.pl

  • Goal: create identied entities with all relationships explicitly exported

    • Disconnected battery
    • Bouncy switch

4.2. Powderkeg: teaching Clojure to Spark, Igor Ges, Christophe Grand

5. Day 3

5.1. Adventures in Understanding Documents, Scott Tuddenham

  • Set up the core document processing as (defresource)
  • Standard API end-point for the pixel servers

5.2. Barliman: trying the halting problem backwards, blindfolded, William Byrd, Greg Rosenblatt

  • start with a base test
  • indicate when the data isn't relevant for the tests with ,g1 ,g2
  • indicate recursion cases
  • provide names and formal parameters in the Definitions section
  • speed up a recursive definition with an accumulator
  • apply heursitics like using fold-left or fold-right
  • even proof solvers look reasonable with the minikanren
  • use parsimony as a desired value of a program
