Instant database clones with PostgreSQL 18
PostgreSQL 18 can create near-instant, space-efficient database clones by combining `FILE_COPY` with filesystem reflinks. A 6GB test database cloned in 212ms rather than 67 seconds, with storage consumed only as cloned pages diverge.
How I learned Vulkan and wrote a small game engine with it
Elias Daler built a focused Vulkan game engine and two small demos in roughly three months by prioritizing practical game development over premature abstraction. The write-up distills the renderer architecture, modern Vulkan techniques, and hard-won implementation advice.
🍌 Pico-Banana-400K: A Large-Scale Dataset for Text-Guided Image Editing
Apple’s Pico-Banana-400K provides roughly 400,000 quality-controlled text–image–edit examples for training text-guided image editors, including supervised fine-tuning, preference-learning, and multi-turn data. It combines Open Images sources, Gemini-generated instructions and evaluation, and Nano-Banana edits.
Disco — Self-hosted PaaS for teams outgrowing Render & Heroku
Disco provides a self-hosted, open-source Heroku alternative with git-push deployments, zero-downtime releases, and automatic SSL. It targets teams that need managed-PaaS ergonomics without vendor markup, lock-in, or surrendering data control.
Why I switched from HTMX to Datastar
Datastar replaces the author's HTMX-and-AlpineJS coordination burden with a smaller, server-driven model for component updates and real-time UI. Its SSE-based approach enables multi-user push updates without custom WebSockets or sprawling frontend state.
I Tested Gemini's Nano Banana AI Image Editor—and These 7 Tricks Seriously Impressed Me
Gemini’s Nano Banana makes quick AI image edits—such as object removal, compositing, text generation, and custom filters—surprisingly accessible and often more convincing than Adobe’s generative tools. Its low-resolution output, blur, and lack of precise manual controls still rule it out for professional photo workflows.
iPhone dumbphone
A developer used Apple Configurator to turn an iPhone into a tightly controlled utility device, cutting daily screen time from roughly four hours to two. The setup preserves essential apps while blocking the App Store and all non-whitelisted websites.
Shader Academy
Shader Academy is a free, structured platform for learning GLSL and computer graphics through interactive challenges. Its 198 exercises span introductory 2D shader fundamentals through advanced 3D, procedural-mesh, raymarching, particle, and compute-shader work.
