26.6.2018
The animated GIF always makes me chuckle; on one hand they seem like a relic of the “old web”, on the other hand they aren’t going anywhere and their meme-like presence seem to only make them more popular. If you browse through my media blog posts archives, you’ll notice...

Convert HTML to Markdown
21.6.2018

Uppy File Uploading
11.6.2018

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

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...

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...

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...
