Show HN: OmniDiff – Opensource, super fast, content aware Git difftool, in Rust I have been researching what the ultimate diff tool would look like, based on actual diffs in open source repositories. OmniDiff can diff: code (25 languages), config, images, PDFs, archives, cursors, fonts... It's fast. It can diff C++ files of tens of thousands of lines in under 100ms, on a 2023 ThinkPad T14s. It's open source. AGPLv3. It's based on real diffs. I looked at the 7400 repositories that are listed in Gentoo packages, sampled 2000 diffs and solved them manually to get a good understanding of what is needed, before putting together the diff pipelines for each content type. Incidentally, this also forms the basis of the CI pipeline, so the robustness of the codebase is quite high. I'm still developing it. It's v0.3.0 at this time. But I have been using it daily as my git difftool for months now, and it works well. AI Disclosure: Yes, I do use AI. No, I do not vibecode. https://ift.tt/IvUsud4 November 1, 2026 at 03:02AM

Show HN: Point your camera at a landscape to learn about its geology https://ift.tt/AeBYMQU

Show HN: Point your camera at a landscape to learn about its geology I've been working on a fun little app that paints geologic maps over landscapes using augmented reality. You can use it to identify what the mapped rocks are, read descriptions about them, and view the earth as it looked when they formed by turning back the continent positions. It spun out of some augmented reality work I was doing on my other side project app - Flyover Country, which tells you about the view from the airplane window. I'm in Minnesota, so i haven't had a chance to test it on a huge amount of terrain (the best I've found is the Mississippi River gorge in the twin cities... I need a trip up north), so anyone that's somewhere with some more bumps: please help!). It's stuck in the Apple review queue, but it's up on testflight for anyone interested. Google approved it quickly and it's fully out on android (links to both on the marketing site). edit: got a report that testflight was asking for an install code. Seems like a testflight app issue, but dismissing it and installing as normal seems to work! https://outcrop.rocks/ October 29, 2026 at 05:22AM
