I made a WebGL mechanical clock simulation if anyone wants to look at it in motion: https://clock.leshenko.net/

> 8051s love talking to each other after all, otherwise USB would not exist. Can anyone explain what the author meant by that? I thought 8051 is just an ISA, is there something spe…

Great presentation! I created something similar — a step-by-step Git implementation that is designed for teaching Git internals: https://www.leshenko.net/p/ugit/

Awesome post! I'm confused about the schematics of the keyboard and I wonder if anybody here might point me in the right direction: The HWB pin is pulled permanently low, so the MC…

> Git is one of those technologies where it's super important to get a good grasp of how to internals work. I fully agree, that's why I built a tutorial where you learn about Git i…

Looks nice, I wanted to submit a project and I spent time to fill the forms but I was greeted with a login wall after I filled all the details. There was no indication anywhere in …

I've seen people's Git skills improve after I taught them Git internals, but I taught them in a standard lecture format. I didn't try teaching Git internals using code before, but …

> stripped of factors that obscure the lesson Yes! I'm going to adopt that wording. Originally I tried to do a screencast about guided Git source code exploration but it didn't wor…

It was custom made for the tutorial. I didn't release it yet because I mostly focused on polishing the tutorial itself and not the code for the interface. Do you think people would…

I'm happy to hear that! You can clone the tutorial content using the link in the "Download" section. The interface isn't available yet on Github.

Thanks! Note that ugit isn't supposed to be a custom compatible Git implementation, but rather a simplified Git-like implementation for teaching Git concepts. So even if ugit suppo…

Sure, thanks for doing it! I added a license to the original code.

A while ago I made a bouncing DVD logo that would actually hit the corner every few bounces with high probability: https://nikital.github.io/screensaver (But then it would troll yo…

I think it's important to distinguish between the concept of the init process vs specific implementations of the init process. The article talks about the init process in general (…

xkcd has a self-enumerating comic: https://xkcd.com/688/

Cool, I made this toy some years ago :) Thanks for the additions, merged your code into the original.

No, you can't call syscalls from restartable sequences

A restartable sequence is defined by a start and an end offset. If I write a restarable sequence in C I can't be absolutely sure that it's contiguous and I can't know where the com…

The module takes an extra reference count to itself upon initialization and never decrements it, so rmmod will fail because the module will be "in use".

I used the kernel module for a few days and didn't notice any problems on a laptop running Fedora. The kernel module is less that 100 lines long, hopefully it's simple enough to no…

According to the article, the self-mapping PTE is randomized in the latest Windows 10.
