Requirements

• no upfront installation/agents on remote/slave machines - ssh should be enough
• application components should use third-party software, e.g. HDFS, Spark's cluster, deployed separately
• configuration templating
• environment requires/asserts, i.e. we need a JVM in a given version before doing deployment
• deployment process run from Jenkins

Solution

Vec3 Magnitude

These C# implementations of approximate magnitude with no square roots are actually slower than calling a native implementation in Unity, but if this were implemented intelligently in C there's a good chance they would be faster. In any case, they're here because it was a pain to get the magic numbers.

Accurate to within 4.5%.

logE = math.log(2)
logB = (value) ->

  return math.floor(math.log(value) / logE)

-- implementation of a binary minimum heap
-- use a function closure for instance creation
-- instead of tables
-- this yields us truly private variables and an
-- overall cleaner package
