I'm working on exploring an exploit in physical security systems that I haven't seen anyone investigate before (at least, not published on the internet). It's involved an interesting combination of reverse engineering, pentesting and regular prototyping/hardware development. Currently writing a run-through of it to publish on my website. I'm not sure how secretive to be - I think I just want to be the first to actual…

What's your website?

I'm working on a system that helps surgeons make precise bone cuts during knee replacement surgery. Believe it or not, manual cuts are still the standard in that type of procedure. Robotic systems exist but they are very costly, big, and actually add time to the surgery (bad news when you are under anesthesia and your leg is in a tourniquet). It uses 4k stereoscopic capture and bunch of ML models to match bone positi…

This sounds awesome! Can you tell me more about what kind of expertise do you need to develop such a system? As in the most important knowledge one most have to be able to work on such a thing

Esperanto havas la mal- prefikso por krei specialcelan antonomion, sed la rezulto ofte mankas klarecon, kaj kiel morfemo mal mem estas morale kondamna: komparu malica, maligna, malversacio kie mal ne estas sinkrone disigebla. Tial mi vorkas por krei liston de ĉiuj mal- vortoj kun sen mal- alternativoj. Fakte ĝi ankaŭ povas servi la kontraŭan celon, provizi pli ĝeneralajn mal- vortojn kiam oni deziras krei verkon pli…

This smells of doubleplusungood.

I still am not sure exactly how to define it, but it's a ruby library, that is mix of a rules engine+spreadsheet feelings+array language+static validation+compiled/codegen... that last part is mostly not merged yet but yeah, ruby DSL codegenerating ruby, it's ruby all the way.

TrailerSpoiler.com [0]

It annoys me how much a bad trailer can spoil the movie, so I made this platform to rate trailers how "spoily" they are and how good they are. To my surprise, you find some great trailers without many spoilers, but then you will have trailers which are basically a 3-min summary of the movie.

I’m building a daily word puzzle game with a twist! In Tiled Words you rearrange tiles to solve clues and rebuild a broken crossword. You can play a demo at https://tiledwords.com - it’s free and web based so it works on whatever device you’ve got. I’ll be officially launching on October 19th at the Portland Retro Gaming Expo. You can sign up to be notified on launch. Starting then there will be a new puzzle every da…

love the UI! one feedback I have is it would be nice to be able to use arrow keys on the desktop website to move the tiles

"Google maps but for old maps": https://pastmaps.com This is a solo startup that I've been working on for 2 years now. It's a labor of love and I'm very lucky and thankful that it's big enough to surprisingly pay all of our bills. Still constantly feeling FOMO over all of my startup buddies working with AI and LLMs while I plug away at old maps and GIS . It gets ~80K MAUs and just slowly and consistently is growing o…

Nice project! The National Library of Scotland has a nifty tool focused mainly on the UK and Ireland that does something similar (with a paid print service attached): https://maps.nls.uk/geo/find/marker/

I am working on Octelium https://github.com/octelium/octelium a FOSS unified zero trust secure access platform that is flexible enough to operate as a modern zero-config remote access VPN, a Zero Trust Network Access (ZTNA)/BeyondCorp platform, an API/AI/LLM gateway, an infrastructure for MCP gateways and agentic AI architectures/meshes, a PaaS-like platform, ngrok alternative, and even as a homelab infrastructure. I…

Can you communicate the value of Octelium in 25 words or less?
