Show HN: A lightweight mapping editor for improving MTB trails on OpenStreetMap

Hacker News - 2 hours 41 min ago

I wanted to share a lightweight mapping editor I’ve built to make it easier to improve MTB trail data on OpenStreetMap. In general MTB trails on OSM could be greatly improved, especially when it comes to IMBA ratings and I wanted to lower the barrier to entry to contributing to OSM.

Key features:

* Load satellite, lidar or OSM GPS traces to verify trail paths * Dedicated keybindings for quickly tagging a trail's IMBA rating and other actions * Add, edit and split trails to improve trail accuracy * Circle a group of trails to add or update a trail network * Load all trails in a given state or region (US and Canada supported to start) * Upload to OSM as a changeset

Hope some folks find this useful, let me know what feedback you have!

Show HN: Ototo: A tool to offload code exploration to a smaller model

Hacker News - 4 hours 1 min ago

Hey all - I made a thing with my clanker Kevin: Ototo (https://ototo.dev/) - yes this is clanker driven dev. The idea is to offload code exploration and other token'y heavy tasks to a smaller model to do the work and chuck the result back. This helps in a couple of ways (1) it saves tokens if you can offload to a cheaper or free local model (2) it can keep the main context clearer as it removes all the sherlocking thinking/exploration. It also saves more tokens than using anthropics own exploration agent.

I had originally played around with a graph based approach but found this to work better. Currently, I have this running with Qwen 3.8 27B on my framework (I had Kevin build me a custom inference engine to squeeze all the juice I could out of the AMD - https://gitlab.com/handmadedigital/projects/shocho).

It's been through a bunch of tests (results are available if people want) against a load of different repos, including comparing subsequent commits of large repos with claude, claude + exploration agent and claude + ototo and so far ototo seems to really help.

The site is very 'LLM'y at the moment - I haven't had time to edit it to make the text more readable for us humans. Sorry.

Hope it helps folks in their day-to-day.

Show HN: I recreated "Crazy Ones" ad as an animated web tribute to Steve Jobs

Hacker News - 4 hours 2 min ago

Today marks 15 years since Steve Jobs died. I remember watching his narrated version of "Here’s to the crazy ones" that day and crying. It felt like he was reading his own obituary. The ad suddenly seemed to have been about him all along.

When I first saw the original as a teenager, I decided to buy a Mac. It took me four years of saving. I still think it’s the best ad ever made: it never mentions a product, but it sold me on the whole company.

To mark the anniversary, I recreated it as an animated monochrome experience that runs in the browser, with Jobs' original narration.

I used Claude Opus 5.5 (ultracode) for the code, animation, and sound design, GPT-Image-2.5 for the illustrations, and ElevenLabs for the music. The voice is Jobs’s actual recording, isolated from the original soundtrack.
