Node.js streams demystified

A quick overview of the node.js streams interface with basic examples.

This is based on @brycebaril's presentation, Node.js Streams2 Demystified

Overview

Streams are a first-class construct in Node.js for handling data.

Think of them as as lazy evaluation applied to data.

WebRTC Data Channels
// This is a bare bones example of creating a data channel between two WebRTC
// peers. Let's imagine two peers trying to connect to each other. We'll call
// one the "offer peer", and the other the "answer peer". The offer peer will
// be the one initiating a connection, and the answer peer will be the one
// responding to it.
//
// The two peers must use a separate connection to negotiate their connection.
// A websocket connection to a shared server is often used for this negotiation.
// They will exchange offers and answers using the websocket. Each peer will
// also attempt to discover more details about themselves (ICE), such as their

Ordering with SQL by nearest latitude & longitude coordinates (MySQL & SQLite)
---
METHOD 1
This should roughly sort the items on distance in MySQL, and should work in SQLite.
If you need to sort them preciser, you could try using the Pythagorean theorem (a^2 + b^2 = c^2) to get the exact distance.

SELECT *
FROM table
ORDER BY ((lat-$user_lat)*(lat-$user_lat)) + ((lng - $user_lng)*(lng - $user_lng)) ASC
