I learned a bunch, creating vados and integrating it with Netlify to have my page about bass playing. Mostly how to use html templates in Rust, to generate html fast. Also some basic Rust things relearned since it's been a while using Rust.

That's awesome! 🔥

I learned the fundamentals of PostgreSQL and WebRTC. I used it to write a tutorial on how to build a Twitter Spaces/Clubhouse clone 😁! Here's the article series:

Awesome!

I've been learning Typescript this week. Also I've been programming in Python for years now and I just found out that the "//" operator is floor division and not integer division.

[Nick Taylor]

Nice!

onMouseEnter/Leave events. Creating variants with props and styled components. Creating animation utility components. Lots of JavaScript stuff that I can't seem to remember currently.

Brain is fried. First couple weeks of the javascript journey are tough.

Since your brain is fried, here’s some fried chicken.

Seems like I'm in my first couple of weeks right now 🤣

Was waiting for this one! I learned about reducing complexity with early returns in node, and about managing race conditions in testing.

I learned Apollo/GraphQL (for front end) and made a GitHub Topic Explorer using the GitHub API.

Also learned what I was doing wrong with Redux in a project. Hilarious. I needed to add a default reducer that returns state itself 😂

Learned more about writing semantic HTML. Already familiar, but pushing myself to write more screen reader friendly code! Yay accessibility!

Next: jest / unit testing 🤩

[Nick Taylor]

Yeah!

3. Understood how to configure heap affinitization for the .NET GC via this post.
4. Linux has no concept of CPU groups like how Windows does for > 64 cores.

[Nick Taylor]
