Foundations — idlemachines
idlemachines.co.uk/courses/foundationsStart here if you're new to ML. In nineteen problems we'll get from dot products to a working training loop, all in NumPy. Implement the building blocks (sigmoid, softmax, cross-entropy, attention masks), then build a linear layer and work through the backwards passes that make training work.

Decorative Cryptography
www.dlp.rip/decorative-cryptographyLast year, I came agross a Linux kernel feature called TCG_TPM2_HMAC. It claims to detect or prevent active and passive interposer attackers.
It all sounds really great. We should care about interposer adversaries. It’s great to use the TPM features that were invented to help us with these problems.

Inside Windows 3
www.xtof.info/inside-windows3.htmlWindows 3 is often said to be just an UI on top of DOS. This article presents some of the inner side of Windows 3.x and will show that it is more ambitious and advanced than that.

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.

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-synthesisersThis 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.

Comptime Zig ORM
matklad.github.io/2025/03/19/comptime-zig-orm.htmlThis post can be considered an advanced Zig tutorial. I will be covering some of the more unique
aspects of the language, but won't be explaining the easy part. If you haven't read the Zig
Language Reference, you might start there. Additionally,
we will also learn the foundational trick for implementing relational model.

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!

Why I love Rust for tokenising and parsing

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.)

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.
