Who is @horse_js?

22.1.2019
Many of us follow @horse_js on Twitter. Twenty-one thousand of us, to be exact. That horse loves stirring up mischief by taking people's statements out of context. It happened to me a few times and almost got me in trouble. I wonder how many people hate CSS because their experience with...

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...

The peculiar magic of flexbox and auto margins

27.7.2018
In front-end development, there are often times when I know that I don’t know something. I might know enough to know what CSS to search for, but I have absolutely no idea how to use it or what the right syntax is. Somehow, in my head, there appears to be a filing cabinet that’s entirely empty,...

Automate Your Workflow with Node

18.7.2018
You know those tedious tasks you have to do at work: Updating configuration files, copying and pasting files, updating Jira tickets. Time adds up after a while.

React Node Flow

27.6.2018

19.6.2018
I don't think this is an epidemic or anything, but I've seen it done a few times and even advocated for. This is what I mean... You go to Google Fonts and pick a font like Open Sans, and it gives you either a <link> or an @import with a URL there in which to ready this font for usage...
