Hi HN, TamedTable is an LLM harness for data ETL. And yes, it was developed using AI, meaning you can take the entire specification and recreate it to your desires: https://github.com/ZSvedic/TamedTable

Hi HN, I built Btfy, an experimental blockchain that uses weather observations as a source of unpredictability for consensus The motivation is simple. Proof of Work generates uncertainty by performing computations. I wanted to explore whether we could obtain some of that uncertainty from the real world instead. Btfy combines weather observation data with a Verifiable Delay Function (VDF): Weather Observation Data -> VDF -> Block -> Hash Chain In the current implementation, observation data is co

This is a submission for Frontend Challenge - Comfort Food Edition, CSS Art . Inspiration Hyderabadi dum biryani is more than a dish to me—it is a ritual. The sealed handi, the slow charcoal heat, the suspense before the atta crust is broken, and the first rush of saffron, mint, birista, and spice all feel inseparable from the experience. I wanted to turn that moment into an interactive midnight poster: Hyderabad’s skyline behind a copper handi, with the food hidden until the viewer breaks the seal. Demo Click BREAK THE SEAL to lift the lid and reveal the four biryani layers. How it works The artwork is built with HTML and CSS only: A native <details> / <summary> control stores the open and closed states. CSS :has() coordinates the seal crack, lid lift, layer reveal, steam, labels, embers, and state-aware copy. Rice grains, mint leaves, birista, spices, meat, copper patina, flour dust, the skyline, and the moon are all CSS shapes. There are no images, SVGs, canvas, JavaScript, gradients, or frameworks. A mobile composition and prefers-reduced-motion keep the piece responsive and accessible. The reveal is deliberately choreographed: seal cracks → lid lifts → layers separate → labels arrive → steam settles Journey The hardest part was keeping the illustration detailed without losing the strong poster silhouette. I iterated on three areas: Material: hammered copper marks, soot, flour residue, dough cracks, and print texture. Depth: curved food layers, overlapping grains, steam arches, and ingredient silhouettes. Motion: a staged opening sequence rather than making every element animate at once. The most satisfying decision was using a semantic HTML control for the interaction. The artwork still works with a keyboard, and disabling motion does not hide the final state. I used Codex as an iterative coding and visual-critique partner. I directed the concept, cultural references, composition, and final decisions, while the agent helped implement and test the CSS system. Wh
