Show HN: Turn your name into a tree in an infinite procedural shanshui landscape Hi HN! I made this after collecting hundreds of "name → tree" submissions at ITP. Live: https://ift.tt/w57FPsY Source: https://ift.tt/5RgkYSE Plant a tree: https://ift.tt/ZftDg7b Pan and zoom an infinite procedural landscape. Each name is converted to ASCII codes, which grow into a unique tree (breadth-first branching; repeated digits become mathematical roses). Mountains use midpoint displacement + Perlin noise, with SVG radial gradients in the blue/green/gold palette from Wang Ximeng's "A Thousand Li of Rivers and Mountains." Inspired by Lingdong Huang's {Shan, Shui}* ( https://ift.tt/v3ZmyRc ). Every tree is someone's name, signed with an APack stamp ( https://ift.tt/gLYtarV ). Try planting your name, then pan along the ridgeline to find it. "My trees" lets you jump back to ones you planted. Happy to answer questions about the terrain algo, name→tree encoding, or the Riso print we tiled at ITP Winter Show! https://ift.tt/w57FPsY June 10, 2026 at 08:09PM

Show HN: AVP – an agent can't leak a secret it never had https://ift.tt/W64d1Tx

Show HN: AVP – an agent can't leak a secret it never had A process can't leak a secret it never had. Shai-hulud, prompt-injection - you name it. They cannot steal what your agent (or an process) don't have. I run coding agents (Claude Code, Codex) on my own machines most of the day. Every one of them wants real API keys in env and I was scratching my head for the last few months how to contain it. The usual answer to this is a firewall. I don't buy it. A firewall tries to contain a secret the process is still holding, and the rules are painful to maintain. AVP gives the agent a placeholder and injects the real value at the last moment, on the wire: ``` # the agent's env holds only a placeholder STRIPE_API_KEY=avp-placeholder # agent sends: Authorization: Bearer avp-placeholder # AVP forwards upstream: Authorization: Bearer sk_live_...real... ``` Keep your passwords in your vault where they belong. AVP initially relies on Bitwarden as a secret manager. It's MIT licensed. Appreciate any feedback. https://ift.tt/tHA8djv June 12, 2026 at 12:40AM

Let Muni Move You Through the Summer

Let Muni Move You Through the Summer
By Melissa Culross

San Francisco is a magical place all year, including and especially during summertime. (Photo credit: Unsplash) There’s nothing like summer in San Francisco. You may need a jacket thanks to the fog and cool conditions, but summer still heats up in the city, despite any weather forecast. There is so much to do, especially this year. And thanks to Muni and our entire transportation system, getting to summer events is easy. You can hop on a bus, train or streetcar and enjoy the season. If you drive, walk or bike, you can count on our parking control officers to keep traffic moving and help you...

Show HN: Stillwind – High Resolution Electronic Component Search https://ift.tt/1Afjp6o

Show HN: Stillwind – High Resolution Electronic Component Search We’ve spent the last couple of months building Stillwind Search, a search engine for electronic components that helps users find parts that fit even the most complex set of specifications. After talking to the people that actually build PCBs we found out that finding the exact part you are looking for, is consuming enormous amounts of times, is very tedious and then often doesn’t yield the best results. So we tried to cut down this search time by just requiring a (broad) description of the specifications and we find the correct part in minutes, not hours. This is possible through our own database of parts and their properties. We used LLMs to extract every parameter about a part into >1k schemas, collectively covering more than 130k properties. This depth of properties could no longer be visualized, so the database is queried interactively by an AI agent (Sonnet 4.6) to find the needle in the haystack of parts. Before results are shown, we use another model to verify the data (that’s why it might take a moment before the first results appear). We currently have almost all microcontrollers, sensors, and other advanced ICs on the market, as well as a wide selection of passives and generic parts. We are working on adding more parts and are more than happy to take suggestions. I know that folks on HN like technical details on how this works, so let me give a short overview: Frontend: SvelteKit + Cloudflare Workers + Hyperdrive Backend: PostgreSQL 18 (with io_uring) database, with extensions on NVMe drives hosted on a beefy server. We appreciate all feedback and are happy to answer any questions :) Btw: We are already working on a way that you can search combinations of parts, finding the optimal combination of parts. https://stillwind.ai June 11, 2026 at 11:42PM
