@WierdKebab @LexnLin Thinking the same thing. It’s getting clicks for $$ though.

@LexnLin What is happening here?

Vibecoded this nav bar, using paperjs :)

共通約数があるものには引力を、互いに素なものは斥力を働かせるというシンプルなプログラムを作ってみたら、決して安定しないものが生まれた。複雑な人間模様を見ているよう・・

@edwinkite @astro_takubo @CJHandmer It’s like a 4D fingerprint of our solar system. Cool visualization.

Solar sail trajectory from low earth orbit to Mars. (1) Escape from earth (spiral up from ~800km); (2) Navigate through interplanetary space; and (3) Spiral down / get captured at Mars. Top-down visualization, work by Ari Essunfeld and @astro_takubo, idea by @CJHandmer.

@javarevisited Include background processes.

@javarevisited Network, disk space, how query is created & called, explain plan, JVM (GC logs) and jit

Your database CPU usage is only 20%, but query latency has suddenly increased from 50ms to 800ms. Where would you investigate first?

📝 As a software engineer, you need to acquire enough knowledge to be able to think for yourself. 📉 This has always been the case, as, otherwise, you'd fall for Cargo Cult programming or follow irrelevant trends. 🤖 Today, this is even more relevant. Being able to tell whether AI is correct or hallucinates is what differentiates professional engineers from amateur coders. And, the only way to increase your knowledge is to never stop learning. Reading good books, watching relevant courses, participating in workshops, and building prototypes will give you an edge over other humans or machines.

Happy New Year (2026) Project Panama for Newbies Part 1-4 articles were updated (Java 25) before the new year!!! foojay.io/today/project-… foojay.io/today/project-… foojay.io/today/project-… foojay.io/today/project-… Happy coding! #opengl #java #native #jni #jna #jnr #gaming #ml #ai

I meant SDL2.

Migrating articles Project Panama for newbies Parts 1-4 to the latest FFI & FFM APIs in Java 25. Keep on the look out for Part 3. It is not ready, but I was able to compile and run on Apple Silicon M4 using Java 25 SLD2 and OpenGL. foojay.io/today/project-… #java #native #opengl

Project Panama for Newbies (Part 2) on foojay.io was Updated Dec 29, 2025: This article now features Java 25 and the Foreign Function & Memory (FFM) API, which has been a standard feature since JDK 22. foojay.io/today/project-… Part 3-4 will be a work in progress.🙂

@IheanyiAguwa You are welcome! Tutorials 2-4 are being updated soon. I hope human written articles are still in fashion.🤪

@carldea Thanks I've been looking forward to this update.

@chessMan786 Who knows maybe @OpenRewrite has recipes that will. It’s already happening with Java and JavaScript.
