Get Viewport Lines and Columns in CodeMirror

27.11.2018
CodeMirror is an amazing utility for presenting code in a browser environment.  Syntax highlighting, widgets, and a number of advanced functions make it a unique, useful tool.  When using CodeMirror inside the Firefox DevTools debugger, I found that adding hundreds of column breakpoint widgets...

Replace Last Command in Shell

26.11.2018
Whether I fat-finger a command or my MacBook Pro keyboard’s keys don’t want to respond like they should, I’m frequently misspelling commands.  What’s more frustrating is that many of these commands are long, taking making fixing theme time-consuming. Luckily a Twitter...

Object.fromEntries

9.11.2018
The Object object has been buffed with useful methods over the past few years.  Object.keys, Object.values, Object.freeze, and Object.assign all address frequently desired functionality.  One of the new Object methods is fromEntries, which accepts a Map or map-like array nesting and converts it...

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...

Turn Bluetooth On and Off from Command Line on macOS

6.11.2018
Bluetooth has been a revelation in wireless technology: wireless mice, headphones, streaming devices, and a variety of home and office environments.  It goes without saying that wireless peripherals are so much easier to manage than wired counterparts, especially mice, that I usually have...

Get Up and Win

5.11.2018
Down on my hands and knees, I crawl around, bleeding out.  I’m resigned to my fate.  A kind stranger, a new friend, rushes over to me and kneels to help, reviving me at a time that didn’t require it.  Just as I’m revived, the kind stranger says “Get up and win”.  I...

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...

Change System Volume from Command Line on Mac OS

15.10.2018
Oftentimes the awesome GUI applications we love are simply gloss over a command line functionality.  While I do love a visual app, it’s always good to know how to do things from command line, if only for the sake of automation.  I’ve covered loads of command line secrets, most notably...

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...
