This is a really nice resource for beginners who are getting into low-level development, as well as simply understanding the device they are using to read this very webpage.

Take a look at your process tree, it’s likely that you might notice a new service: rtkit-daemon, the RealtimeKit Daemon. It seems nobody on the internet is talking about it, so let’s explain what it’s about in this article.

Building a Modern Computer From First Principles

Great content for learning about CPU design and computer architecture, via hands-on build videos

Curious exactly what happens when you run a program on your computer? Read this article to learn how multiprocessing works, what system calls really are, how computers manage memory with hardware interrupts, and how Linux loads executables.

For the longest time, I thought Instruments on macOS wasn’t for me. Whenever I saw its icon show up in the /Applications folder or pop up in a launcher, I assumed it’s part of Xcode and Xcode is an IDE for Objective-C and Swift programmers and that’s not what I do and that’s why Instruments isn’t for me.

Video overview of all the processes used to make a microchip, as well as an overview of a microchip factory.

What happens when you run a program on your computer (multiprocessing, system calls, memory management, hardware interrupts…).

Examples on how branch prediction can get in the way of performance.

CPU utilization has become a deeply misleading metric: it includes cycles waiting on main memory, which can dominate modern workloads.

An educational puzzle game. Solve a series of tasks where you build increasingly powerful components. Starts with the simplest logical components and ends up with a programmable computer.

Different ways to visualize device utilization across multiple devices, and how that utilization is changing over time.
