Convert HTML to Markdown

21.6.2018
One of my biggest mistakes with this blog was not finding a WordPress plugin that would allow me to write my posts with markdown; to this day I still need to write posts in “Visual” mode and then manually convert the post to HTML for “Text” mode. One of these days I want...

Show FPS for Steam Games

18.6.2018
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 between...

Uppy File Uploading

11.6.2018
One of the big tasks I was charged with at my first job was setting up a system by which any customer or potential customer (aka anonymous user) could upload PDF and image files. I had loads of constraints to deal with: browser support, server settings, variance in user tech knowledge, etc....

console.logTime

7.6.2018
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 detailed console.time...

OpenRates Currency API (Sponsored)

30.5.2018
Creating your own APIs can be a total nightmare: worrying about uptime, load balancing, data accuracy, caching, and all of the other risks would keep me up at night. And if your API relates to money in any way? If you get that wrong you could be costing yourself, your employer, or your client...

How to Delete Untracked Files in a Mercurial Repository

29.5.2018
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 up with...

Regain Disk Space from Homebrew

21.5.2018
One of my favorite utilities is Homebrew, the shell utility for installing and upgrading other utilities — it’s a lazy developer’s dream. Dreams can easily turn to nightmares, however, and I recently learned that Homebrew caches older versions of installed packages, leading...

Custom List Number Styling

18.5.2018
How about a classic CSS trick! This isn't even so tricky anymore, since CSS has counter-increment and counter-reset and such that is perfect for this. I just wanted to make sure you knew how it works and had some easy-to-copy examples at the ready. Let's say all you wanna do is style the dang...

Detect WebVR Support with JavaScript

16.5.2018
It’s been two years since I was heavily involved with WebVR at Mozilla but, despite not contributing every day, I can see VR making leaps and bounds, from Firefox making an increased effort to Chrome pushing VR and Oculus and HTC (Vive) improving their offerings. Native games are getting...

The backdrop-filter CSS property

16.5.2018
I had never heard of the backdrop-filter property until yesterday, but after a couple of hours messing around with it I’m positive that it’s nothing more than magic. This is because it adds filters (like changing the hue, contrast or blur) of the background of an element without changing the text...

CDN, Web Security, and DDoS Protection from Incapsula (Sponsored)

16.5.2018
There used to be day that you could have a small to large website that didn’t require protection and worldwide CDN but, with how easy it is to initiate a DDoS attack and how important website speed is for search engine placement, it’s a given that you should look for a service to handle...

Get a React Component by DOM Node

15.5.2018
Retrieving a React component’s DOM node is fairly simple from within the component itself, but what if you want to work backward: retrieve a component’s instance by DOM node? This is a task that the old Dojo Toolkit’s Dijit framework allowed with the dojo.byId method, so it made...

How to Get a React Component’s Element

14.5.2018
JSX is an amazing pseudo-language for React, and if I’m honest, it’s what brought me to love React so much. Using React without JSX is cumbersome and frustrating, while using JSX is such an easier way to express your code. One drawback of JSX, however, is that it makes accessing...

Decorating lines of text with box-decoration-break

8.5.2018
An institution’s motto, an artist’s intro, a company’s tagline, a community’s principle, a service’s greeting… all of them have one thing in common: they’re one brief paragraph displayed on a website’s home page — or at least the about page! It’s rare that just one word or one line of text...

Vertically Centering with Flexbox

8.5.2018
Vertically centering sibling child contents is a task we’ve long needed on the web but has always seemed way more difficult than it should be. We initially used tables to accomplish the task, then moved on to CSS and JavaScript tricks because table layout was horribly inefficient —...
