About memory pressure, lock contention, and Data-oriented Design, https://mnt.io/articles/about-memory-pressure-lock-contention-and-data-oriented-design/.

I illustrate how Data-oriented Design helped to remove annoying memory pressure and lock contention in multiple sorters used in the Matrix Rust SDK. It has improved the execution by 98.7% (53ms to 676µs) and the throughput by 7718.5% (from 18Kelem/s to 1.4Melem/s)!

Most Java applications carry a service layer by default.
Often without questioning why.

In this hands-on Quarkus tutorial, I build a complete Order API without services.
Business logic lives in pure functions.
All outcomes are modeled explicitly with records and sealed types.

Less indirection.
Better tests.
Clearer code.

I broke down Event Sourcing in Quarkus using Java records, sealed types, pure functions, and a clean CQRS split.

Fully hands-on. No magic. Just data, folds, and clear architecture.
If you want to understand event sourcing without the hype, this one is for you.

#MoonBit looks like a really interesting new #ProgrammingLanguage  

https://www.moonbitlang.com/

Especially its functional, data-oriented design and #WASM support stand out to me.

Looks _a lot_ like #Rust, but more functional in style. ✨

It is expected to reach 1.0 this year. 👀

I've been programming professionally for almost thirty years. I'm a fan of OOP; it has served me very well.

Java has been making a lot of changes and at first I didn't see the point. Why use sealed classes and pattern matching when a good ol' object hierarchy would do the job?

I discovered "data oriented design", how it's the "opposite" of OOP, and am starting to grasp when it'd make more sense

All these "state management" solutions of the "modern web" like #Redux, Zustand or whatever try to solve state management in UI apps by introducing unfathomable amount of complexity...

...when in reality all you need is #Bevy's #ECS. ¯\_(ツ)_/¯

Practical Data-oriented Design, https://www.youtube.com/watch?v=IroPQ150F6c by @andrewrk. That's an amazing talk, with concrete examples on the Zig compiler.

Andrew Kelley - Practical #DOD

In this #talk, Andrew Kelley (creator of #ZigLang), presents how they've sped up the #Zig #compiler and significantly reduced its memory usage by applying data-oriented design for the compiler's data structures.

A phenomenal talk! I highly recommend it.

Hi #PHP Community, I just came across a talk about #DataOrientedDesign and #MemoryAlignment during my lunch break. I'm familiar with the concept in Golang and C projects and I've always designed my structs accordingly. I am currently working in a PHP environment and since performance and low memory footprints are never really requirements here anyway, I haven't pursued memory alignment any further for the time being.
