What it does
Hexcalibur is a browser-based pixel art editor for game artists. Paint block textures in 2D and watch them update live on a 3D block, animate sprites on a frame-by-frame timeline, and build tilesets with autotiling. Everything is organized as packs - manage and export a whole texture set as one unit, with engine-aware exports for Minecraft (Java + Bedrock), Tiled, Godot, Unity, Three.js, and Babylon. No install, humans place every pixel. Free to start, Pro when you need more.

Hexcalibur is a browser-based pixel-art editor for voxel-game block textures. Real-time 3D preview, pack workflow, an animation timeline, and engine-ready exports for Minecraft, Tiled, and the indie engine stack - free to start. A live 3D preview rotates while you paint. Single cube for simple blocks, L-stack for stairs and slabs, so the texture wraps across multiple adjacent faces. Watch the seams meet in real time. No reload loop, no guesswork, no surprise mismatches when you ship. A pack holds every asset for one resource pack: textures, palette, references. Switch between assets without opening a new file. Lock a shared palette across the pack so your stone and your dirt agree on what…from axidus.io

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
