- explained from first principles great too https://explained-from-first-principles.com/

Yes, I'm always happy to receive feedback, either via email or a GitHub issue: https://github.com/KasparEtter/ef1p/issues :-)

Nand to Tetris.The Elements of Computing Systems: Building a Modern Computer from First Principles

Free (also some paid online certificate programs).

At least worth a look.

Pebble Graphics is a modern take on Logo/turtle graphics partially inspired by stories of people’s first programming experiences on the Apple II with turtle graphics and partially influenced by essays like Bret Victor’s Learnable Programming [1]. It’s a 3D user interface for programming that emphasizes interactivity (being able to put together a program with 3D pieces and step forward and backward through execution as you’re building) and visualization of state and execution history.

It’s been a bit of a journey to get to this point and it started here on Hacker News. I was first inspired to try out VR after seeing this post [2] of a live coding environment in VR by Brian Peiris back in 2014. After working on my own multi-user version of that project [3] I thought more about non keyboard interfaces for making programs since it wasn’t that easy with a headset on. After a few experiments, I ended up with a project where you could put together JavaScript abstract syntax trees with your hands and interactively execute them [4]. I took a brief break and then decided to see if there was anything interesting at the lower levels of computation and also take some time to study the amazing Nand to Tetris course [5], which resulted in a VR circuit simulator [6], VR CPU Emulator [7], and a very limited version of turtle graphics in VR [8]. A lot of this work was done at the wonderful Recurse Center [9], which I highly recommend and through some great discussions with members of the community there were a few stories of how people got their start in programming with turtle graphics so I decided to make a more user friendly version. I had a long time interest in startups and entrepreneurship so I took this as an opportunity to learn about that process as well and here we are. Here’s a playlist [10] of the app's development over time and the channel has some other VR and programming experiments as well. Thanks for taking the time to look!

I've played it a bit with my kids. It seems to take a similar to the Nand 2 Tetris course: https://www.nand2tetris.org/

This was an amazing course and is one of the most rewarding computer science courses I've taken! I loved that there was nothing left to "magic" and it was the first time I felt like I understood the "full stack" of the Java-like code I was writing right down to the silicon atoms.

Self-plug for a full-blown minesweeper game I made for the final project: https://github.com/billmei/nand2minesweeper It's a complete game with a tutorial, custom RNG, and unit tests, using their hardware simulator.
