Tracking NixOS option values and dependencies | oddlama's blog
oddlama.org/blog/tracking-options-in-nixosThere are thousands of options in NixOS, but as users, we usually only interact with a select few of them. Despite that, a huge amount of those options does influence the final result in some way. Have you ever wondered which of them were actually relevant for your specific system?

Rewriting Kafka in Rust Async: Insights and Lessons Learned in Rust | Rex Wang
wangjunfei.com/2025/06/18/Rewriting-Kafka-in-Rust-Async-Insights-and-Lessons-Learned#SummaryAchieving high-performance asynchronous Rust projects transcends mere usage of the async/await syntax; it fundamentally relies on a deep understanding of the underlying task scheduling, lock optimization, and architecture design principles.

How fast are Linux pipes anyway?
mazzo.li/posts/fast-pipes.htmlPipes are ubiquitous in Unix --- but how fast can they go on Linux? In this post we'll iteratively improve a simple pipe-writing benchmark from 3.5GiB/s to 65GiB/s, guided by Linux

The power of interning: making a time series database 2000x smaller in Rust | Blog | Guillaume Endignoux
gendignoux.com/blog/2025/03/03/rust-interning-2000x.htmlIn this deep dive post, I’ll explain how I used the interning design pattern in Rust to compress this data set by a factor of two thousand! We’ll investigate how to best structure the interner itself, how to tune our data schema to work well with it, and likewise how serialization can best leverage interning.

Optimization adventures: making a parallel Rust workload 10x faster with (or without) Rayon | Blog | Guillaume Endignoux
gendignoux.com/blog/2024/11/18/rust-rayon-optimized.htmlIn a previous post, I’ve shown how to use the rayon framework in Rust to automatically parallelize a loop computation across multiple CPU cores.
In this post, I’ll first explain which profiling tools I used to chase optimizations, before diving into how I built a faster replacement of Rayon for my use case. In the next post, I’ll describe the other optimizations that made my code much faster. Spoiler alert: copying some data sped up my code!

Notes on Distributed Systems for Young Bloods – Something Similar
www.somethingsimilar.com/2013/01/14/notes-on-distributed-systems-for-young-bloodsBelow is a list of some lessons I’ve learned as a distributed systems engineer that are worth being told to a new engineer. Some are subtle, and some are surprising, but none are controversial. This list is for the new distributed systems engineer to guide their thinking about the field they are taking on. It’s not comprehensive, but it’s a good beginning.

Overloaded fields, type safety, and you
educatedguesswork.org/posts/text-type-safetyThe underlying problem we are facing here with all these examples is the same: having the same set of bits which can mean two different things and needing some way to distinguish those two meanings. Failure to do so leads to ambiguity at best and serious defects at worst. That's why you see so much emphasis in modern systems on type safety and on strict domain separation between different meanings.

Build your own SQS or Kafka with Postgres

We think Sequin's cool, but you don't need to adopt the project to get started with streaming in Postgres. In fact, you can turn Postgres into a basic queue/stream pretty easily. Below, we share what we've learned so you
