Converting Color Spaces in JavaScript
10.1.2019
A challenge I faced in building an image "emojifier" was that I needed to change the color spaces of values obtained using getImageData() from RGB to HSL. I used arrays of emojis arranged by brightness and saturation, and they were HSL-based for the best matches of average pixel colors with...
An Initial Implementation of clip-path: path();
24.12.2018
One thing that has long surprised (and saddened) me is that the clip-path property, as awesome as it is, only takes a few values. The circle() and ellipse() functions are nice, but hiding overflows and rounding with border-radius generally helps there already. Perhaps the most useful value...

Getting Started With Google Cloud Functions and MongoDB

Serverless architectures are becoming increasingly popular, and with good reason. In my experience, container-based orchestration frameworks have a steep learning curve and are overkill for most co
HSL() / HSLa() is great for programmatic color control
1.6.2018
If you ever need to hand-manipulate a color in native CSS, HSL is pretty much the only way. HSL (the hsl() and hsla() functions in CSS) stands for hue, saturation, lightness, and optionally, alpha. We've talked about it before but we can break it down a little more and do some interesting things...
Forms, Auth and Serverless Functions on Gatsby and Netlify

Abstracting infrastructure is in our DNA. Roads, schools, water supply networks—you get the idea. Web development is no exception: serverless architectures are a beautiful expression of that phenomenon. Static sites, in particular, are turning into dynamic, rich experiences.
