@tyrionstark__ @kshitijandquant Inside the machine and OSTEP(OS in 3 easy pieces) to pique your curiosity before you go deep into architecture, SIMD intrinsics.

@vivekgalatage Thanks for sharing this!

@Adriksh I think you should enforce this as a constraint in your ring buffer. It would be good to explicitly check, if its a power of 2, else throw.

@pyquantnews @pyquantnews, the most cracked book on Python fundamentals I've read recently is "Fluent Python" aka the Lizard book. That's a minimum for any serious python quant-dev.

It's a wrap for 2025! I would like to share some cool C++ implementations with google tests, it was fun to think about these and are a great mental workout. For low-level data-structures, I like to write the unit-tests first; it gives you a chance to think of the interface and corner cases. 🚀 ➕ 🙌 🙂 🎄

Hi all,
This year, I have been documenting my C++/Rust coding journey. You'll find a collection of no-fluff code snippets, challenge puzzles, deep-dives on concurrency/perf topics. I also plan to blog about my neovim/tmux setup. If you enjoy nerding out, consider subscribing to the newsletter.

@kshitijandquant I would be interested in co-authoring/writing an efficient implementation.

[Quasar Chunawala @quantdev_uk]

@jino_rohit I write a C++ blog at https://t.co/nopAOV1VGJ. I think you'll like some of the stuff there.
