VCamper: use LLMs to spot security fixes before CVE publication Once a patch for a security vulnerability is public, the patch itself can reveal the vulnerability before the CVE is published. VCamper uses a staged LLM pipeline to analyze a Git commit range and flag likely vulnerability patches, even when they look like routine changes. It’s still a proof of concept, but on known cases like curl CVE-2025-0725 it got close to the published root cause from the patch alone. This matters because LLMs could make it much harder to keep security fixes quiet: once the patch is public, the bug may be recoverable almost immediately. Quietly shipping a fix and hoping it stays under the radar may stop being a reliable strategy. https://github.com/rndhouse/vcamper

Building something that finally stops making me the tester for my own AI. You know that moment where the AI finishes writing code and then goes "can you run this and check if it works?" I got tired of that loop. So I built an IDE that just... runs it, clicks through it, finds what broke, and fixes it. You watch. Not Better Cursor , But what comes after it.

https://kavla.dev/ I've worked with data my entire career. We need to alt tab so much. What if we put it all on a canvas? Thats what I'm building with Kavla! Right now working on a CLI that connects a user's local machine to a canvas via websockets. It's open source here: https://github.com/aleda145/kavla-cli Next steps I want to do more stuff with agents. I have a feeling that the canvas is an awesome interace to see agents working. Built with tldraw, duckdb and cloudflare

I've got a mobile app. It allows you to get a wake up call from someone friendly, somewhere out there in the world. It's got a handful of regular users and it's mostly me making the calls, but it's great fun to wake people up! No phone number required - these are VoIP calls via the app. Built it because I think it's cool.

Building a pro transparency writing tool that cryptographically proves a human actually typed what they claim to have written (research papers, news articles, assignments etc) . It captures behavioral signals during composition, makes it very hard to automate or fake the writing process, and lets readers verify authorship authenticity. Think "proof of human work" for the AI generated slop era.

From another submission ( https://news.ycombinator.com/item?id=47738827 ), there was a screenshot of Google Docs/Drive showing a popup saying "You cannot do copy/cut/paste with the mouse" whenever you try to right-click and copy. Some months ago, I saw that very popup, and finally started working on something I've been wanted to do for a long-time, a spreadsheet application. It's cross-platform (looks and work identical across Windows, macOS and Linux), lightweight, and does what a spreadsheet application should be able to do, in the way you expect it, forever. As an extra benefit, I can finally open some spreadsheets that grown out of control (+100MB and growing) without having to go and make a cup of coffee while the spreadsheet loads. I don't really have any concrete to share, I guess it'll be a Show HN eventually, but I thought it was funny it was brought up in a similar way in that article as was the motivation for me to build yet another spreadsheet application.

I evolved an rsync based backup script I've been using for almost a decade into https://github.com/nickjj/bmsu . I use this for backing up my life's work to an external drive but also syncing files to my laptop and phone too. It supports easy restoring as well. No traffic ever leaves your local network and since it uses rsync under the hood the devices being sync'd to don't need to run anything other than SSH. It's a single file shell script that has no dependencies except rsync. It's literally 1,000+ lines of defensive checks and validations to make sure you're not shooting yourself in the foot with rsync, and at the end the last line of code directly calls rsync. It doesn't try to reinvent the wheel by replacing rsync (it's an amazing tool).

Games. Well, mostly tooling surrounding them it seems. In the last 2 months I've made a pixel art editor for Android, a headless population simulator(still balancing parameters on this one, not enough NPC's turn to crime at present, and I've also run into some weird issues with market prices, in one instance the price of meat rose enough to cause a integer overflow. I could switch to i64, but honestly meat was supposed to cost around 20 moneys, not 2³² I'm also working on a 2d procedural animation plugin for bevy, a autotiling plugin for bevy (using 16 tile-dual grid, which the default bevy autotiling plug-in didn't support) and ofc my android pixel editor now has a rig editor mode and a tile editor mode that integrates with the plugins. Making video games is hard! I keep getting side tracked!

I believe that AI-powered software development means we need to fundamentally rethink how we preserve code quality. Model output volumes mean that code review only as a final check before merge is way too late, and far too burdensome. Using AI to review AI-generated code is a band-aid, but not a cure. That's why I built Caliper ( http://getcaliper.dev ). It's a system that institutes multiple layers of code quality checks throughout the dev cycle. The lightest-weight checks get executed after every agent turn, and then increasingly more complex checks get run pre-commit and pre-merge. Early users love it, and the data demonstrates the need - 40% of agent turns produce code that violates a project's own conventions (as defined in CLAUDE.md). Caliper catches those violations immediately and gets the model to make corrections before small issues become costly to unwind. Still very early, and all feedback is welcome! http://getcaliper.dev
