Editor's Notes

  1. http://bit.ly/1zNznip - #Chrome Devtools introduces new feature in#JavaScript debugging called Blackbox script. These are marked scripts will be skipped in the debugging on the control flow chain. So that I don't wait control switch back from 3rd party library script or some other script you not interested
  2. http://bit.ly/1ttWX1t - #http/2 version is cooking very hot, these are the few draft based implementation on various lang. #http/2 is not complete revamp of #http/1. It just add few functionalities and tweaks to improve the #performance. Whats special in #http/2 1) Unlike http/1 where multiple request made from web client to server to achieve concurrency and reduced latency. #http/2 use the same connection for multiple requests. It more like one connection between client and web server 2) In #http/2, prioritising requests are possible 3) Interactive mode available in #http/2 in which Server can Push responses to client. Means, to trade of latency of network. Server send a PUSH_PROMISE frame. Later server synthesis a request and send response in separate stream 3) #http/2 community, actively touch with TLS community for version identification If you have time and willingness, Please contribute to
