I came across a question: How does one efficiently solve Two Sum in C? There’s a naive quadratic time solution, but also an amortized linear time solution using a hash table. Without a built-in or standard library hash table, the latter sounds onerous. However, a mask-step-index table , a hash table construction…
Listen, I didn’t plan on making a whole ‘writing X like Y’ series. But here we are.
Wondering about Rust? We're addressing rumors and providing insight gained from years of early adoption of Rust here at Google.
Wouldn't it be cool to be able to develop terminal applets like UI components?
Thank you to Seth Brown, Eric Oestrich, and Kevin Rankin for reviewing this article.
Linux From Scratch or LFS is a project that provides and maintains a set of instructions of how to build your own Linux system from scratch. I am always curious to understand how things work ‘under the hood’, and since I’m a daily Linux user i decided to take on the challenge to try and complete building Linux From…
In this article I will take a look at the classic concurrent ring buffer and how it can be optimized to increase throughput.
Building agents with LLM (large language model) as its core controller is a cool concept. Several proof-of-concepts demos, such as AutoGPT, GPT-Engineer and BabyAGI, serve as inspiring examples. The potentiality of LLM extends beyond generating well-written copies, stories, essays and programs; it can be framed as a…
Check out the impressive results of the large-scale Folia test that took place on June 18th, 2023. Learn more about our findings and technical challenges in this post.
Take a practical approach to containerization as we guide you through the step-by-step process of building your own Docker-like environment using Linux namespaces, cgroups, and chroot. Dive into the code and command examples to gain a deeper understanding of how these technologies work together to create isolated and…
Nix builds at speeds you never thought possible.
Made by interviewers for candidates – we spent hundreds of hours talking to technical interviewers from FAANG about their processes.
There is a strange thing that I noticed as I progressed from a junior engineer to mid-career to senior. When you’re a new engineer, still learning the basics, you are given a task or you have an idea, and you proceed to implement exactly that idea. Very simple, point A to point B, whatever gets the job done. You hate…
How Microsoft's ruthless employee evaluation system annihilated team collaboration.
Okay, campers, rise and shine...
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…

A very good friend of mine has been experimenting with trying to coax Chat-GPT4 to successfully do basic coding tasks. So have a lot of people these days, of course. In an idle moment, though, my friend submitted the following query:
Version 4.0.0 is available! WeeChat now follows a practical semantic versioning and there are breaking changes in this release, please read carefully the release notes. See
A look at TypeScript’s structural type system, and we how we can effectively use it to our benefit.
Like almost all rules, there are cases where breaking them is a good idea and seasoned writers may well object with "but" responses for some of these. Thus, consider the rules below as mental rumble strips - you should probably slow down and think if you encounter these cases.

Embeddings, why they’re useful, and how we can store and use them in Convex.
We investigate how the data cache influences the performance of your program, talk about ways for you to write faster programs by better leveraging the data cache.
A different view on two's complement math.
Did you know that ground stations transmit signals to satellites 22,236 miles above the equator in geostationary orbits, and that those signals are then beamed down to the entire North American subcontinent? Satellite radios today serve hundreds of channels across 9,540,000 square miles. Unless you’re working at a…
I've spent most of the last decade exploring this area (mainly to design Vale 's memory safety) and I've discovered some surprising things .
