I mainly use LinkedIn to see how much better my former colleagues are now doing, compared to my career progress. When not stalking former colleagues I A/B test[1] my spam posts about my canvas library[2] to see which variants generate

I, too, have had fun playing with TensorFlow and MediaPipe to manipulate live video feed and change the background image. My experience is that MediaPipe's SelfieSegmentation model[1] is a lot quicker at identifying the foreground face

I think the talk video (last on the linked page) does a really good job of explaining the problems surrounding natural vs digital (RGB) pigments mixing, and how the Mixbox folks overcame them to create good-looking outcomes.

I use my phone mainly as a pocket watch; also it has a token generator thing on it which I need for work. The map app is sometimes useful, though I've never been very good at relating the map to the streets around me. I have a couple o

Following up on my comment (for posterity). I've now released the new code to my library. Includes a demo of using the full range of CSS color strings to set color in the canvas[1], and also a demo of my reducePalette (with dithering)

The approach I finally settled on was: check each pixel in the image to build up a list of (RGB) most popular colors and to memoize new colors into LAB values; sort the color data into commonest first; then build up the required palette fro

Just before Christmas I got an urge to add a dither filter to my JS canvas library. The past few weeks have certainly been a very intense adventure through a very deep rabbit hole involving color spaces, color distances and discovering how

I have a side project[1] that has made me $0 over the past 8 years. It's not well known and few, if any, other developers make use of it. I still work on it most days because I enjoy working on it. I assume I'm part of the majorit

Back in the mid-90s I was referred to a specialist because my excessive snoring was giving me sleep apnoea. The consultant advised that I needed throat reconstruction surgery to cure the problem. He asked me if I smoked. Expecting yet anoth

I agree with this, plus the "it's fun" reason others have mentioned. I started work on my canvas library (licence: MIT) 8 years ago mainly so I'd have something to showcase to potential employers. It worked: the reason I

That's an interesting effect. I assume the affected blocks are set up so that each row uses the glitch factor of the row above and varies from it by a (small) random value? I recently wrote a glitch filter for my canvas library[1]. It

How accessible are Lottie animations? Can they include (keyboard accessible) hotspot links? ARIA markup? How much work would it take to make sure a Lottie animation respected user preferences like prefers-reduced-motion?

I had a look at both WebAssembly and Rust a few months back, in the hope they could help me write some nice, fast graphics filters that I could then compile out and use via Wasm in a 2d canvas. Entirely do-able, but beyond my limits of unde

Thanks for the suggestion! Currently I'm looking at this site[1], though some of the words and phrases sound a bit made up to me. The animations are really cool! [1] - Self-organising textures - https://distill.pub/self

That site annoys me! I can find my library on it if I type its name (Scrawl-canvas) in the search bar, but it never appears when searching by tag (eg: 'canvas') and there's no obvious thing I can change in the edit panel to m

A write-up of the processes/algorithms being used to generate the images would add more excitement to the article. Is the author running P5.js in a script serverside and using a headless browser (PhantomJS or equivalent) to generate th

My problem isn't fear of failure. Rather it's something around fear of being in the spotlight, or fear of being ridiculed, that keeps me from marketing my canvas library more aggressively. For instance, I've submitted to HN v

I don't feel particularly exploited - but then my OS library is not particularly popular (or widely used). I suppose if the library did become popular and some $MegaCorp built a cash printing product on top of it I could add some code

One of the first things I did after learning about - and getting excited by - Svelte, was to try and get my canvas library to play nicely with it.[1] Given the rapid development Svelte has endured over the past 18 months I have no idea whet
