Blame It On The Bike!
YouTube video by Dave Pagurek
youtu.be
The Ontario Government is trying to strip out bike lanes we just got finished building and is adding lots of red tape to the process of adding new bike lanes. I got annoyed enough that I wrote, recorded, and animated this protest song in a week. Go call Doug Ford!! youtu.be/Z9vsHzj_-ZU

someone on the p5 discord challenged someone to make the Pluribus intro in p5.js. I got nerd sniped a bit, here's a quick attempt with p5.strands to do some particle animation

My day job is making a video editor where every component is actually a p5.js sketch. If that's of use to anyone for Genuary, you can sign up for a dev account via this link www.usebutter.com/register?cod... and see some docs/examples here! www.usebutter.com/docs

This week's #WCCChallenge theme is "almost." Nothing technically complex going on here, just a bunch of keyframes I typed in to animate this cat in #p5v2 openprocessing.org/sketch/2832077

I can’t get over the fact that Toronto + Ontario shut down transit on one of the busiest weekends of the year. It’s contempt for the people who live here.
A> when subway is closed you really see how much work it does. Sardine buses. Imagine everyone in cars.
B> it’s bananas the TTC scheduled TWO separate downtown subway closures the 2nd weekend before Xmas. Busiest time. If not emergency why not wait till January doldrums? Punishing organization.

This is a scandal. Designed for 33 min by Metrolinx, operated by TTC slower than a bus
Metrolinx had promised a 33-34 min travel time, with average speeds of 20-21 km/h.
It’s currently 46 mins scheduled (53 mins timed yesterday) with an average speed of 13.5 km/h.
The City of Toronto and TTC need to continue working with Metrolinx to meet that promise.

The City of Toronto seriously needs to get full transit signal priority activated ASAP to help speed up the new Line 6 Finch West, as well as ensure the same for Line 5 Eglinton when it opens. @ttcriders.bsky.social already has a petition to that effect. #TTC #TOpoli www.ttcriders.ca/greenlight

today we're working on the last(?) p5.js WebGPU feature before we're at WebGL feature parity: imageLight(). gotta actually write some new shaders today to do the different blur levels! and get mipmaps to work!

I'm sorry this is COOL AS SHIT
Developer attempts to replicate "Liquid Glass" in CSS, and once finished realizes what she'd actually created is an exploit for a fundamental, previously unknown, and rather serious browser vulnerability

Working on some ways to make p5.strands easier to write for newcomers by taking out some of the callbacks: editor.p5js.org/davepagurek/...

Here’s a question I get a lot:
> “Now that AI can generate front-end UIs for us, what’s the point of learning CSS ourselves?”
I think there are lots of reasons, including that you can use AI much more effectively if you understand CSS yourself.
But is that actually true? Let’s discuss. 🧵

p5 just did a sorta new thing for us: we had a call on Discord to work out some specifics of how to handle dimension mismatches between vectors. Seems small but there are a lot of details to talk through, and we thought a call would be more productive than GitHub.
