Uh, this is way more interesting than I expected. If you'd like to get involved and help us build a better browser for npm packages, raise your hand. It should be quite a enjoyable project to participate in.
I'm asking because I'm building an alternative to npmjs.com, including the admin ui piece
I have a working mvp, although of course it's very 🚧
if this is something you'd like to contribute to, and you've experienced any of these pain points, let me know - always more fun to build together! 🙏

🙋♂️ so ... for reasons:
I would love to know people's frustrations with:
- the current npmjs.com
- admin user flows on npm web ui (and cli, locally)

Doing @joshwcomeau.com Whimsical Animations course. I'm halfway on the first part (particles) and I already learned so much! Totally recommended. Such attention to detail, so well put together, really a work of love.

Josh's interview was AWESOME!
One big thing that I took away from his interview section was to build automations to simplify my life.
I also loved how he thought about performance optimization while writing code.

It’s a super cool concept: me and @kevinpowell.co were both given the same technical interview challenge. We were tasked with building a carousel in 30 minutes, in a mock interview setting.

💥 I did a drawing that breaks down Transformers in AI
Spent a good amount of time on this one, breaking down concepts in a way that someone new to the subject could come away with basic high-level understanding. I hope it's useful!

Well this is remarkable. 😮
Someone built a 3D voxel engine using plain ol’ DOM nodes, no canvas/webgl. And it’s surprisingly performant, since it culls any faces that aren’t currently visible.
Repo: github.com/LayoutitStud...
There’s even a nifty lil’ editor!

Attention Bluesky elders: The artist behind the ANIMORPHS covers is here!
I did flipbooks for all of the Animorphs covers I did, but they appeared in black and white and very small, so I am posting them here so you can see them large and in color. No AI here--just Elastic Reality and painting. You can buy a signed print of this cover here:

I decided ~3 weeks ago to start learning to play guitar, and I’ve been having *so* much fun with it!
The lovely thing about learning new skills is how quickly you progress at first; I’m still terrible, but I’m noticeably less terrible than I was a week ago. 😂

This is true in tech as well. Sometimes folks ask how I got testimonials from prominent devs on my course sites, and the answer is usually that we’ve known each other for many years.
If you’re just starting out, get to know others at the same level. Play the long game.

Talking to one of these types at a con who asked how I 'got in' with so many 'famous writers' who I'd been talking to and I said "we made friends before anyone knew who we were decades ago by striking up interesting conversations and enjoying each other's company" and he kept re-asking the question.
They have come to the convention hoping to "break in" and then find themselves -- shocker! -- a "nobody in the book world." Yeah no shit! We all are! I have gently told guys like this a million times that it takes most of us *years* of hard work but they do not believe that could be true for them. +
