Welp *slaps knee* better get on my way now. 🦋 really hit a critical mass recently, come join us, it's really nice! bsky.app/profile/matthewlein…

After months of training, Copilot finally understands how I write classes.

I’m discussing code changes in my pull request with a robot. I love 2023

Wow, ChatGPT makes hiring much much more difficult and time consuming.

TIL safari does not like top: -99999% in some weird cases It’s ok with -59999% though so we’re cool

My vote for most absurd JS method name: atob() Close second for btoa() developer.mozilla.org/en-US/…

TIL js has or equals (||=) and nullish equals (??=) operators. developer.mozilla.org/en-US/…

Around this time, 20 years ago, I published my first website—a band page on a free cjb.net subdomain, awful flash animation and all.

YIL: On m1 macs, you need to install older versions of node (<15) using shell sessions(?) that are launched in rosetta, or they will be crazy slow. Here's helped me: jurnalanas.com/node-js-mac-m…

And now reflecting on how dev has changed in 10 years...its so good now! Sure I have issues like everyone, but overall its amazing. All the browsers are evergreen. I barely ever have to check cross browser issues. CSS layout is so so much better. So good.

10 years ago today, I opened my first PR on a public open source library (adding touch events to a jQuery plugin). Sadly, it sat without author comment for all 10 years of its life. I did help at least 1 person, so I guess it was mission accomplished.

Finally an excuse to wear my formal sweatpants.

I own cssregions.com (from back when that was a thing), if you know anyone that would like to it for anything, I’m looking to give it away.

Lol had a js bundle size go down 22% by changing a couple imports locations from default to named.

I still think about @desandro's Introducing dropshado.ws announcement page from like 10 years ago. Draggable interactive 3D text (in hindsight maybe kinda z-doggish?) totally blew my mind. Using wacky variable names like `pitch` and `yaw`. Fun era of web demos past...

Highly recommend Carl as a human being and teacher. He was pretty instrumental in my early programming education. If you want to learn GSAP, there’s no better person, and you can’t beat free (for a week)

If your site has a lot of 3rd party widgets (because 2019), adding preconnect links can speed up your page load. I couldn’t find a way to get a full list of site connections, so I made one: preconnect-list.netlify.com/ Record a HAR and drop it in to generate a list of connections.
