  2. node.js high performance javascript library for intensive I/O operations. (like

    HTTP) single threaded, event oriented. built on Chrome’s Javascript runtime (V8) lightweight, efficient, really fast. .. insanely fast. Monday, March 12, 2012
  3. websockets bi-directional, full duplex over a single tcp socket. connection

    remains open = no tcp handshake lightweight protocol = no http headers, 2 byte overhead supported chrome 16, FF 11, IE 10, Opera 10 reducing latency from 150 (http) to 50 ms (sockets) Monday, March 12, 2012
  4. socket.io websockets for the rest of us. fallback transports (yes,

    it also works in IE!!) websockets flash sockets ajax long polling ajax streaming iframe json polling.. Monday, March 12, 2012
  5. knockout.js rich, responsive display with a clean underlying data model.

    declarative bindinds automatic UI refresh dependency tracking templating Monday, March 12, 2012
  6. ... and a fast database! open source, high performance, in-memory,

    key-value data store support master-slave replication really fast! if durability is not needed... insanely fast! Monday, March 12, 2012
  7. real-time web apps node.js + redis + socket.io + knockout.js

    real-time... or close enough? Monday, March 12, 2012
  8. let’s build a really simple real-time game... thanks to @gimenete

    for getting me into node.js! ... and thanks to @jmendiara for the node.js sticker! Thanks! Iván Loire (twitter: @ivanloire) code: https://github.com/iloire/math-race demo: http://letsnode.com:8090/ Monday, March 12, 2012
