[Links of the day] 22/03/2016: VPN chart, Hyperloglog in real life, NLP

• VPN comparison chart : if you need VPN with certain characteristics, this chart if for you. 
• HyperLogLog in practice : google looked at hyper log log (one of my favorite probabilistic datatructure) and optimized it slightly, they came up with a improved version. Great paper with good insight on how to use HLL in real world and make it work even better.
• Deep or Shallow, NLP is Breaking Out : natural langage processing is getting boost from deep and shallow learning. We already saw the result with Skype real time translation, Siri and Cortana. Its just a matter of time before we start to see more and more connected devices with NLP capabilities.
