The most satisfying part of my job is that I occasionally get messages like this, from folks who were able to land a job in part due to my courses. ❤️

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:

Days 32&33 of 100 Days of Code:
Finished The Joy of React 🥳🥳
It was a great course! @joshwcomeau.com goes into so much detail that I ended up with a much deeper understanding of React, even for the concepts I was already familiar with.

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. +

I once made the mistake of downloading Microsoft Edge on my mac. I uninstalled it a long time ago, but Microsoft AutoUpdate remains, and every day it asks me if I want to update the AutoUpdate application. 😂
Just figured out how to erase it. Good riddance.

There’s still time to complete the State of React survey, if you haven’t yet!
These surveys are both a community service *and* a great way to learn about modern React features. Win-win 😄

Researchers have found two new vulnerabilities in React Server Components while attempting to exploit the patches last week.
These are new issues, separate from the critical CVE last week. The patch for React2Shell remains effective for the Remote Code Execution exploit.

Bruno’s *last* portfolio site was one of the coolest things I’d ever seen on the web. I don’t even have vocabulary for this one. 😂
6 years of thinking I can make a better portfolio.
1 year of actually building it.
My new portfolio is LIVE 🚀
Please, don't break anything!

✨ Exciting proposal alert: the CPU Performance API.
This proposal will add `navigator.cpuPerformance`, a value that measures the broad performance capability of the CPU.
That way, we can scale up/down our animations to make sure everyone has the best experience possible for their device. 😄
