Three Questions to Ask of Every Bug You Encounter

19.11.2018
Bugs. Errors. Exceptions. Problems. Issues. Whatever you call them in the moment, bugs are deeply associated with failure. Specifically, our own failure to write perfect code. These “failures” can

Download a YouTube Channel’s Videos

7.11.2018
YouTube is an endless source of entertainment, be it stuff you’re proud to share you like or stuff you would rather others not know about (see: David’s history of watching old WWE Royal Rumbles).  I watch a lot of YouTube in hotels and on flights when I don’t have internet access...

Lessons in Failure: Removing the Old Debugger from Firefox

29.10.2018
Joining the Firefox DevTools team was a dream come true for me.  I shared why in the first episode of the Script & Style show but the quick summary is that I grew up loving Firefox (even before it was called “Firefox”) because Mozilla cared about developers via their early developer...

Mercurial: Mass Add and Remove All Files

29.10.2018
While I much prefer git and the GitHub workflow, Firefox’s codebase (mozilla-central) is store in a mercurial repository.  There are tools that wrap mercurial so you can use a git-like interface, like git-cinnabar, but my philosophy is to learn the root tool so that I know what’s going...

Change Mac Brightness from Command Line

24.10.2018
Earlier this week I posted about how you can modify your Mac’s volume from command line.  Little command line scripts make me smile because I spend so much of my day in command line, and automation can be the key to productivity.  I next thought about modifying brightness from command line...

Find and Change Default App for File Type from Command Line

23.10.2018
There are few things more frustrating to any computer user than files opening in an unwanted application.  Sure you can use the Open menu item in the desired application but we all just want to double-click a file and see it open in the application we expect.  I recently got to thinking about this...

Real-time Geolocation & Reverse IP Lookup with ipapi (Sponsored)

22.10.2018
There’s an incredible amount you can do when you know where your web visitor is located.  You can target advertising to the user, you can load maps of nearby search queries, you can localize website verbiage, you can customize content for their region, etc.  I guess what I’m trying...

How to Get and Set CSS Variable Values with JavaScript

8.10.2018
CSS variables are a very welcome addition to the language, despite them being incredibly basic.  Sure we could use SASS or stylus but languages should never count on developers relying on frameworks and toolkits to accomplish what we know we need.  And just like every other part of a webpage,...

Team Management with monday.com

25.9.2018
Experimenting with monday.com was an eye-opening experience; I always knew that team management was difficult but it always seemed like you’d need half a dozen pieces of software to bring it all together; think HR, team management, task management, CRM, billing…organization of all...

How to Get Green Blood in PUBG

24.9.2018
My current video game obsession is Player Unknown’s Battleground, also referred to as PUBG.  It’s an online multiplayer game which drops yourself and 99 others into a single, large map and you battle it out until the last man is standing.  It’s frustrating, heart-attack inducing...

Stuff you can do with CSS pointer events

27.7.2018
Martijn Cuppens (the same fella with the very weird div!) has some more irresistible CSS trickery. Three of the examples are about making a child element trigger an event on a parent element (almost like the magic that is :focus-within). Here's how I reasoned it out to myself: You know how if...

Sometimes `sizes` is quite important.

27.7.2018
Paraphrased question from email: I just read your article Responsive Images: If you’re just changing resolutions, use srcset. In the age of "responsive websites," srcset does not help in certain situations. For example, I have a popular products slider. On mobile, I have one image per slide where...

Teaching Your Clients How to Use The Website You Built Them

27.7.2018
I share my own thoughts on how you might go about educating someone you just built a site for. But it turns out I had a lot of fun putting together a ton of other people's thoughts as well. I tweeted about it and got a flood of responses, so this article is an amalgamation of all that. Direct...

Recent Videos!

27.7.2018
I've recorded a decent number of videos lately, most of which are pairing with someone and digging into a topic as I glean as much information as I can! Several of these are sponsored, in that they are a part of an advertising package. Hopefully, you know me well enough that I don't work with...

This post is the third in a series about the power of CSS. Article Series: Colorizing SVG Backgrounds Dropdown Menus Logical Styling Based On the Number of Given Elements (this post) Did you know that CSS is Turing complete? Did you know that you can use it to do some pretty serious logical...

Build Firefox Faster with Artifact Builds

26.7.2018
Working on Firefox DevTools has always been a dream of mine, mostly because it feels like the ultimate way to give back to the development community and those that helped me become a success.  And when I explain who Mozilla is and people ask “Oh, so you work on Firefox?!”, I can finally...
