Tracking NixOS option values and dependencies | oddlama's blog

oddlama.org/blog/tracking-options-in-nixos

There 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?

A security model for systemd

lwn.net/Articles/1042888

Poettering 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"".

Nick Appleton’s blog and stuff - Building a digital filter for use in synthesisers

www.appletonaudio.com/blog/2022/building-a-digital-filter-for-use-in-synthesisers

This is a tutorial on how to build a digital implementation of a 2nd-order, continuously-variable filter (i.e. one where you can change the parameters runtime) that has dynamic behaviour that mimics an analogue filter.

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.html

In 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.

Computational Journalism | At the Tow Center for Digital Journalism

compjournalism.com

The 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.)

What is the best pointer tagging method?

coredumped.dev/2024/09/09/what-is-the-best-pointer-tagging-method

In this post, we are going to take a deep dive into pointer tagging, where metadata is encoded into a word-sized pointer. Doing so allows us to keep a compact representation that can be passed around in machine registers. This is very common in implementing dynamic programming languages, but can really be used anywhere that additional runtime information is needed about a pointer. We will look at a handful of different ways these pointers can be encoded and see how the compiler can optimize them for different hardware.

Overloaded fields, type safety, and you

educatedguesswork.org/posts/text-type-safety

The 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.
