Simple program that uses the adafruit thermal printer to print out whatever messages you send it, currently it supports bold and underlined text, this sketch requires the Adafruit_Thermal library, which can be found here on GitHub, anything the program prints to serial is purely for debug purposes
#include <Adafruit_Thermal.h>
#include <SoftwareSerial.h>
#define PRINTER_RX 12
#define PRINTER_TX 13
#define SERIAL_BAUD 9600
Adafruit_Thermal printer(PRINTER_RX, PRINTER_TX);
boolean stringComplete = false;

ElectricCoffee / Obj-C Selectors.m
Created October 27, 2013 10:25
From one of my projects, I'm keeping this way of doing it for future reference, so I won't forget; the project currently uses function pointers instead; but this could come in handy.
double invokeCalculator(id object, SEL method, double price, double extraItemPrice, int index) {
double returnValue = 0xDEAD;
if([object respondsToSelector:method]) {
NSLog(@"object responded sucessfully");
NSInvocation* invocation =
[NSInvocation invocationWithMethodSignature: [object methodSignatureForSelector: method]];
[invocation setTarget: object]; // index 0
[invocation setSelector: method]; // index 1
[invocation setArgument: &price atIndex: 2]; // index 2

based off of the codecademy dragon slayer tutorial program, but with loads of stuff added
var slaying = true;
var youHit = function() {
return Math.round(Math.random());
};
var damageThisRound = 0;
var damage = function(min, max) {
return Math.floor(Math.random() * max + min);
};

ElectricCoffee / attempts.scala
Created April 3, 2014 08:37
Basic method that lets you attempt to get a result up to a given number of times
def attempt[T,E <: Exception](attempts: Int, subject: String, failedMessage: String, exception: E, failCondition: T => Boolean)(body: => T): T = {
val i = body
if(failCondition(i) && attempts != 0) {
println(s"Subject: $subject")
println(s"Message: $failedMessage")
println(s"Attempts left: $attempts")
// do something with the exception
attempt(attempts - 1, subject, failedMessage, exception, failCondition)(body)
}
else i

val (b, a) = (stack.pop, stack.pop)
stack push op(a,b)
}
