$ sudo add-apt-repository ppa:wireguard/wireguard
$ sudo apt-get update
$ sudo apt-get install wireguard

MacOS
$ brew install wireguard-tools

Generate key your key pairs.  The key pairs are just that, key pairs.  They can be

Processing LiDAR to extract building heights

Walk through

Detailed walk through of building extraction using postgis

First lets pull a data layer from of openstreetmap. You can do this any which way you’d like, as there are a variety of methods for pulling openstreetmap data from their database. Check the [wiki] (http://wiki.openstreetmap.org/wiki/Downloading_data) for a comprehensive list. My favourite method thus far is pulling the data straight into QGIS using the open layers plugin. For those who may want to explore this method, check [this tutorial] (http://www.qgistutorials.com/en/docs/downloading_osm_data.html). For building extraction you only need building footprints, and include the building tags. Not all polygons are of type building in OSM, so we can download all the polygons, and then filter the layer for only polygons tagged as buildings.

LiDAR data was pulled from USGS via the Earth Explorer site. [Here] (http://earthobservatory.nasa.gov/blogs/ele

Asynchronicity is the price to pay, you better know what you're paying for...

Let's share some vocabulary first:

Thread: The primitive responsible of executing code on the processor, you can give an existing (or a new) Thread some code, and it will execute it. Normally you can have a few hundreds on a JVM, arguments that you can tweak your way out to thousands. Worth noting that multitasking is achieved when using multiple Threads. Multiple Threads can exist for a single processor in which case multitasking happens when this processor switches between threads, called context switching, which will give the impression of things happenning in parallel. An example of a direct, and probably naive, use of a new Thread in Java:

public class MyRunnable implements Runnable {
  public void run(){
 System.out.println("MyRunnable running");
