agasta Agasta's blog: open source, maps, AI agents, diagrams and Rust. https://agasta.dev/blog/ 2026-11-08T00:00:00.000Z Agasta We built an AI research lab in Slack for our student group, and it caught its own mistakes https://agasta.dev/blog/raccoonlabs/ 2026-11-08T00:00:00.000Z 2026-11-08T00:00:00.000Z Six AI lab members on Claude Code, Codex and OpenCode, a human professor at every gate, and a sealed paper to prove we didn't steer. Here's what four hours of real research looked like. Deleting the poisoned page doesn't undo what your agents did with it https://agasta.dev/blog/poisoned-page/ 2026-10-18T00:00:00.000Z 2026-10-18T00:00:00.000Z One injected web page told my support agents to refund anyone claiming VIP. Deleting the page didn't undo what the agents had already learned from it. I got tired of AI diagram slop, so I built an open-source AI diagram generator on Excalidraw https://agasta.dev/blog/opendiagram/ 2026-09-26T00:00:00.000Z 2026-09-26T00:00:00.000Z AI kept giving me unreadable architecture diagrams, so I built an open-source generator on Excalidraw where the LLM never touches pixels. How I Rebuilt OpenStreetMap’s Category Model During GSoC https://nominatim.org/2026/09/01/gsoc-2026-nominatim-categories.html 2026-09-01T00:00:00.000Z 2026-09-01T00:00:00.000Z How I gave Nominatim a real category model during Google Summer of Code 2026. GSoC 2026 final summary: category support in Nominatim https://www.openstreetmap.org/user/Agasta07/diary/409236 2026-08-22T00:00:00.000Z 2026-08-22T00:00:00.000Z My OpenStreetMap diary entry for GSoC 2026. Are you still using a router-orchestrator for your agents in 2026? https://agasta.dev/blog/router-orchestrator/ 2026-08-04T00:00:00.000Z 2026-08-04T00:00:00.000Z The router-orchestrator pattern lived in our codebase until it didn't. Here's what replaced it. GSoC midterm: category support in Nominatim, first half report https://www.openstreetmap.org/user/Agasta07/diary/409035 2026-07-12T00:00:00.000Z 2026-07-12T00:00:00.000Z My OpenStreetMap diary entry for GSoC 2026. Adding a column to 22 million rows without melting the database https://agasta.dev/blog/22-million-rows/ 2026-07-11T00:00:00.000Z 2026-07-11T00:00:00.000Z One harmless-looking migration on a 22 million row table, and the boring three-step pattern that stopped it locking everything. I needed cross-platform screen capture in Rust, so I built pinray https://agasta.dev/blog/pinray/ 2026-07-06T00:00:00.000Z 2026-07-06T00:00:00.000Z Cross-platform screen capture in Rust should be a solved problem. It wasn't, so I built pinray. Got into GSoC 2026!
