mindoftea / bluetoothLagTest

Created June 21, 2014 22:09

Node-bluetooth-serial-port writing lag test case. Writing consistently takes 250ms to complete on OSX.

	"use strict";

	var bluetooth=require('bluetooth-serial-port');
	bluetooth=new bluetooth.BluetoothSerialPort();

	var write=function()
	{
	var timeStamp;
	console.log("sending...");
	timeStamp=Date.now();

mindoftea / chooser.js

Created June 21, 2014 15:03

A node.js program that helps users sort a list based on subjective criteria.

	"use strict";

	var Prompt=require('prompt');
	Prompt.start();

	var LOW={};
	var HIGH={};

	var sortedList=[LOW,HIGH];
	var unSortedList=[

mindoftea / curryProduct.js

Last active August 29, 2015 14:01

A demonstration of some of the power of closures when used for currying in JavaScript.

	var f=function(x)
	{
	var g=function(y)
	{
	x*=y;
	print(x);
	return g;
	};
	return g;
	};

mindoftea / fastFibonacci.js

Created May 10, 2014 06:08

A recursive, caching JavaScript implementation of the famous Fibonacci function. Each time you call it, it gets faster.

	var fibonacci=function()
	{
	var x=[0,1];
	return function(n)
	{
	if(x[n]!==undefined)
	{
	return x[n];
	}
	else

mindoftea / elGamal.js

Created May 10, 2014 06:04

An implementation of the ElGamal encryption system in JavaScript.

	var Alphabet = "!\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{\|}~ π®ƒ©∆";

	Alphabet = Alphabet.split("");

	var Crypto = function (alpha, gen, C) {
	var p, B, encrypt, decrypt, f, g, modInv, modPow, toAlpha, to10;
	toAlpha = function (x) {
	var y, p, l, n;
	if (x === 0) {
	return "!!!!";

mindoftea / seededRand.js

Created May 10, 2014 05:53

A simple seeded pseudo-random number generator implemented in JavaScript using the Blum Blum Shub method.

	var SeededRand = function(seed, mod1, mod2)
	{
	return function()
	{
	seed = (seedseed) % (mod1mod2);
	return seed/(mod1*mod2);
	};
	};

	var rand = SeededRand(seed, mod1, mod2);

mindoftea / pointChecker.js

Created May 10, 2014 05:50

A javascript function which uses a map to efficiently search for nearby points distributed across a one-dimensional field. There is quite a high up-front cost to initializing the map, but, once that is done, each point-finding operation is extremely cheap.

	var CheckPoints=function(list, spaceSize, scanSize)
	{
	var n,m,map;
	list.sort(
	function(a,b)
	{
	return -(a.x<b.x)+(a.x>b.x);
	}
	);
	map={};
