Can someone please explain to me how can YouTube's transcription transcribe me saying "subroutine" as "subruine"? I though, for all AI's faults, it was supposed to always produce a real word (even if not the one I said).

New video is up! This time, we dive into how the Apple II does I/O, and in particular, reads the keyboard. We then talk about why the way CompuSar went about implementing it just doesn't work, and what can be done about it instead. youtu.be/KQQ84fHnwHs

A new video is up! This time we talk about the magic that is context switching, i.e. - doing more than one thing "at a time" by quickly switching between tasks. youtu.be/VeDDCkWxwUs

I've just released a 30 seconds teaser for the next video, which will talk about preemptive multi-tasking and context switching. It's open to everyone on the channel's Patreon page: patreon.com/posts/video-te…

I've *finally* started putting the components together. A new video is up, in which I connect my synchronous 6502 to the 32 bit Risc-V computer I built, connecting ROMs and booting an Apple II. youtu.be/O8tuOYEDIMY

A new project update video is out on that videos platform. No, that other one. It's two minutes of recap of recent advances in the project. In particular, implementing backpressure in my 6502 implementation. youtu.be/2Snkxg7QlTI

After a too long pause, I'm very happy to announce a new video. This is video #4 in the FPGA concept series. This time we talk about timing analysis. Share and enjoy. youtu.be/bbcqE5LwVr0

So, it seems I have create _yet another_ new FOSS project. This time, it allows you to run nested Linux distributions. Unlike docker, however, the containment here is intentionally shallow. No official release yet. github.com/Shachar/distro…

Over the past several weeks I've been doing weekly live coding sessions for implementing a 6502 in System Verilog. What I did not do is explain _why_. Until now. youtu.be/and5Sfoy9t4
