sdball / googlemaps_loading_lots_of_points.js

Created January 1, 2011 23:29

A sampling of code for loading/unloading thousands of points as the user pans around the map.

	function requestMarkers() {
	// no loading markers when zoomed way out
	if (map.getZoom() < 11) { return };
	// start dropping markers before the browser bogs down
	if (markers.length > 50) {
	dropSuperfluousMarkers();
	}
	$.ajax({
	// [snip typical ajax data request]
	success: populateMarkers,

sdball / apex_fib.apex.java

Created December 13, 2010 18:15

Calculates arbitrary points in the fibonacci sequence using recursion. This is actually salesforce Apex code, not java.

	// this is, obviously, just an apex exploration
	// i.e. horribly inefficient
	Integer fib(Integer n) {
	if (n <= 1) return 1; else return fib(n-1) + fib(n-2);
	}

	for (Integer i=0; i<=12; i++) {
	System.debug(fib(i));
	}
