Understanding how things work has never been more important. From the foundations of computing to the construction of electronic devices, my new book attempts to build a bridge between theory and practice, model and reality, thought and object. leanpub.com/universalmachi…

The next book we're reading in the Software Internals Email Book Club is the 2nd edition of The Art of Multiprocessor Programming. Sign up and volunteer to kick off discussion for one chapter!

I've made a custom, tiny CPU from scratch and I'm now releasing the monorepo for it! 🛠️ Please check out the project here: popovicu.com/mrav-cpu/ GitHub: github.com/popovicu/mrav-… Blog post: popovicu.com/posts/making-a… #embedded #microcontroller #cpu #fpga

Algebra-Driven Design: Elegant Solutions from Simple Building Blocks by Sandy Maguire is the featured book on the Leanpub homepage! #Haskell #SoftwareEngineering #SoftwareArchitecture A how-to field guide on building leak-free abstractions and algebraically designing real-world

Your Linux distro is just two things: 1. The kernel 2. User-space binaries Once the kernel is ready, it hands off to a SINGLE userspace process: init. Everything else you run – your shell, your apps, your services – is a child of init. This means you can build a Linux system

“In August 2024, tickets for the Oasis reunion tour sold out rapidly, with approximately 1.4 million tickets sold over six hours […] or 65 tickets per second for a high-demand ticket sale scenario.” A phenomenal post by renerocksai⚡ on how he 10x’d this with TigerBeetle.

Do you really understand how Linux works? You can read 1,000 books on theory, but the only way to truly get started with understanding an OS is to build one. I wrote a guide on building a time-sharing kernel from scratch in Zig for RISC-V. It hit #1 on Hacker News. It's a

Your Linux process has a built-in kitchen timer. 🍳 sleep() can handle delays, but that stops your program cold. There's a non-blocking alternative: getitimer. Syscall #36 on x86_64, this lets your code keep running while the clock ticks in the background. 🧵👇

This thread is part of my ongoing "Linux System Call of the Day" series! Every day, I break down one of these syscalls, the vital API that lets your userspace programs ask the Linux kernel to perform powerful operations. Follow along to master the OS from the ground up! 🚀

We've released 10+ Linear Algebra concepts for Machine Learning! Here's one of the visualization how PCA identifies direction of maximum variance.

we have released more blogs today on calculus fundamentals for machine learning and their interactive simulations. some of them includes - > backprop and gradient descents > local minima/saddle points > vector fields > taylor series > jacobian and hessian > partial derivatives

Fascinating Talk by Lindsey on the interplay of distributed systems and interpreters youtube.com/watch?v=q8398P…

I’ve spent 10 years teaching math to machine learning engineers. 80% of university math is irrelevant to your actual job. Luckily, I've created a FREE roadmap to teach you the 20% you actually need. Like, retweet, and comment "roadmap" and I'll DM you the link.

Nice to see it in real life

The 2nd edition of Designing Data-Intensive Applications, by Martin Kleppmann and me, is finished and sent to the printers! Ebooks available next week, and print books in 3–4 weeks. Sigh of relief. 😅 (BTW, this is a good opportunity to support your favourite local bookshop!)
