A security model for systemd
lwn.net/Articles/1042888Poettering said that he does have a vision for how all of the security-related pieces of systemd are meant to fit together. He wanted to use his talk to explain ""how the individual security-related parts of systemd actually fit together and why they exist in the first place"".

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
perf.

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.

Using Nix to Fuzz Test a PDF Parser (Part One)
mtlynch.io/nix-fuzz-testing-1Fuzz testing is a technique for automatically uncovering bugs in software. The problem is that it’s a pain to set up. Read any fuzz testing tutorial, and the first task is an hour of building tools from source and chasing down dependencies upon dependencies.
I recently found that Nix eliminates a lot of the gruntwork from fuzz testing. I created a Nix configuration that kicks off a fuzz testing workflow with a single command.

Computational Journalism | At the Tow Center for Digital Journalism
compjournalism.comThe course is a hands-on, research-level introduction to the areas of computer science that have a direct relevance to journalism, and the broader project of producing an informed and engaged public $100 installment loan. We study two big ideas: the application of computation to produce journalism (such as data science for investigative reporting), and journalism about areas that involve computation (such as the analysis of credit scoring algorithms.)
