    Get Weather from Command Line

    There's an awesome script making the rounds on Twitter and I've been as excited as everyone else so I thought I'd show it.  Many of us live eight hours a day within the command line (although I'm not a vim hippie like some of you) so I try...

    Docker: Remove All Images and Containers

    I've moved to a new project at Mozilla which uses a much different stack than I'm used to; suddenly I'm thrust into a world of Mercurial, Docker, and a few other technologies I'm not accustomed to.  You know what that leads to:  foul language, frustration, booze, and...lots of starting over.

    The console.time and console.timeEnd methods allow developers to time any routine and get a duration in milliseconds.  Since JavaScript performance is becoming increasingly important, it's good to know basic techniques for benchmarking routines.  One of the most basic benchmarking tools is console.time with console.timeEnd. console.time starts the time and console.timeEnd stops the timer and...

    Get Element Dimensions After CSS Transform

    I've been playing a lot with meta viewports recently due to seeing many HTML5 TV apps coded explicitly for 1280x720 which you'll see on many HD televisions.  We all know that it's a much better practice to use responsive design than hardcode dimensions but, that aside, meta...
