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

#topoli Transit Nerd Nation: Line ups in arctic-grade cold to ride a new transit line is about as committed as it gets… www.thestar.com/news/gta/the...
The Eglinton Crosstown LRT opens after 15 years of construction
Many transit fans braved the cold to be among the first to ride Line 5, which was originally set to open in 2020.

I feel like people generally underestimate or maybe under appreciate the amount of time it takes doing the parts is open source that aren't just programming. it's a lot! and it's just as important (if not more so!) for the health of a project

So Adobe are killing Flash for good. I guess it’s on us then, to stay noisy about this, if we ever hope to open our project files for the foreseeable future. (1)

#genuary 31: shaders. Well, it's been mostly shaders this whole month, but here's one more, making a disco ball with starburst lens flares. openprocessing.org/sketch/2860946 #p5js #p5v2

#genuary 30, it's not a bug, it's a feature. WebGL clips away surfaces that are too close or far from the camera. You can control that distance. I've used that to make an x-ray thing here, featuring this completely not cursed creative coded person. openprocessing.org/sketch/2860277 #p5v2 #p5js
