    Show FPS for Steam Games

    There's nothing more frustrating to a top gamer (outside of bugs in a game) than dropped frames in a video game.  If you're playing a competitive multiplayer game like PUBG or Fortnite, where up to 100 people are simultaneously competing, dropped frames can be the difference...

    console.timeLog

    I work on a really complex debugger at Mozilla but, and don't tell my colleagues, I sometimes enjoy simply using console.log and other console commands to get some simple output.  I know, I know, but hey -- whatever gets the job done.  A few years ago I...

    How to Delete Untracked Files in a Mercurial Repository

    Working around Firefox at Mozilla means that you need to get acquainted with mercurial, the version control system that rivals git and svn.  Like any tool, hg (mercurial) can be difficult until you're well versed with it.  And if you hg import a URL that doesn't match...

    Find Empty Files and Directories from Command Line

    If you are anything like me, you like to keep your projects as tight as possible.  By "tight" I mean no lingering, useless files or directories, because bloat is an incredible annoyance and distraction.  And we don't want distractions, do we? There's a really easy way to...

    Better Node.js Console Dumps with console-probe

    Writing JavaScript in the Node.js environment has always felt a bit more difficult; probably because browser developer tools have become incredibly powerful, interactive, and visually appealing.  Using console.log on the client side isn't the best of experiences and obviously isn't interactive. Though not interactive, I've found that

    Faster PR Pulls with Git Aliases

    I love the traditional GitHub workflow of receive pull request, pull down pull request to test, and merge the pull request.  GitHub makes the first and the third steps easy but pulling down pull requests from new contributors requires some boilerplate work that annoys me... ...namely navigating...
