    DOMDocument and UTF-8 Problem

    A few weeks back I shared how I used PHP DOMDocument to reliably update all image URLs from standard HTTP to HTTPS.  DOMDocument made a difficult problem seem incredibly easy ... but with one side-effect that it took me a while to spot:  UTF-8 characters were being...

    Adding ESLint with gulp.js

    I've noticed that I am a loose coder on my personal projects but want some level of decorum on Mozilla and other open source projects.  The more developers you have contributing to a project, the tighter the ship you must keep.  The easiest way to do that is...

    Catching Fatal Errors with Node.js child_process

    I'm relatively new to hardcore Node.js hacking so I'm seeing all sorts of lovely new errors that I have no clue how to solve when I initially see them.  To this point I've managed to keep a smile on my face while trying to fix these...

    Get Directory Size from Shell

    My first goal when coding is usually to make it work and then clean up the code into a more maintainable format.  Many people prefer to keep code clean from start to finish but thinking "maintenance first" slows me down --- I like to GO GO GO!

    Get Git Branches Checked Out on a Date

    I don't use any type of git UI -- I try to be hardcore and stick to the command line.  This makes git usage quicker but I also probably miss out on a lot of the functionality that would be nice to know.  The functionality is there, of course...

    Recursively Delete Files from Command Line

    I'm one of those people who can't stand a messy laptop;  I don't keep around files I don't need and I refuse to install apps unless I absolutely need them.  Unfortunately Mac OS X and Windows generate files whenever they like, like .DS_Store and Thumbs.db.  Sure they serve their purpose...
