8:00 – 5:00 SR

• DB Backups
• Dong discussed Reqonciler with Lenny
• Spent some time chasing down what to do about heartbleed. Since I admin only the VMs, and it appears that the landlord is doing regular updates, I’m trying to determine if I have to do anything in addition to what I’m already doing. Once more, it would really help if we had a real sysadm on the team.
• Today’s big JavaScript breakthrough.The following have the same results, though the Internet says that bind() has more overhead and takes longer.

  // Typical way to handle callbacks
  var self = this;
  setTimeout(function() {self.callbackFn()}, this.delay);

  // More clear?
  setTimeout(this.callbackFn.bind(this), this.delay);

  Interestingly, you can move the inner function out of the callback and into the “Constrictor” (e.g. combination inheritance) so that the function only gets created once:

  function MyClass(){
  var self = this;
  this.boundFunc = function(){self.callbackFn()};
  }

  This allows for a nicer looking call:
  setTimeout(this.boundFunc, this.delay);

  On the whole, I think I like the last pattern the best.
