dorkrawk / singleton_struct.rb
Created December 11, 2014 00:22
A monkeypatch to Ruby Struct to get rid of "warning: redefining constant Struct::whatever" when using Structs
class Struct
def self.new_singleton(name, *fields)
if Struct::const_defined?(name)
Struct.const_get(name)
else
Struct.new(name, *fields)
end
end

dorkrawk / field_set_values.rb
Created July 19, 2013 04:24
Possible long ugly way to get a "field name" => "field value" hash from a Lawn Tent field set.
fs.project.template.fields.map{ |x| fs.field_values.select{|fv| fv.field == x }.map{|fv| {x.name => fv.string_value}}}

Created July 10, 2013 00:16
Use lazy evaluation to compute primes.
def from(n: Int): Stream[Int] = n #:: from(n + 1)
def sieve(s: Stream[Int]): Stream[Int] = s.head #:: sieve(s.tail filter (_ % s.head != 0))
val primes = sieve(from(2))
primes.take(10).toList // produces first 10 primes
primes.take(100).toList // produces first 100 primes

dorkrawk / blue_red_green.ino
Created April 10, 2013 05:03
This is the first little Arduino program I wrote (outside of basic tutorials). It turns on a blue, red, or green LED based on a key stroke. Neat!
char input = 0;
int blue = 9;
int red = 10;
int green = 11;
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
delay(100);
