Patterns for Defensive Programming in Rust | corrode Rust Consulting

corrode.dev/blog/defensive-programming

[...] hard-learned patterns to write more defensive Rust code, learned throughout years of shipping Rust code to production. I’m not talking about design patterns here, but rather small idioms, which are rarely documented, but make a big difference in the overall code quality.

Inside Windows 3

www.xtof.info/inside-windows3.html

Windows 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#Summary

Achieving 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.

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.html

In 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!

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.)

Notes on Distributed Systems for Young Bloods – Something Similar

www.somethingsimilar.com/2013/01/14/notes-on-distributed-systems-for-young-bloods

Below 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.

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.
