I'm working on Zen Notes - a minimal, distraction-free notes app that prioritizes ownership and longevity. The core philosophy is: your notes should be yours forever, that also includes the software stack it's built on. Everything is stored locally in SQLite with standard Markdown, so no vendor lock-in or proprietary formats. The interface is very minimal without flashy colors or icons, so you can focus on your thoug…

Nice design, esp considering you started from scratch. The UI reminds me a lot of Simplenote.

I’m working on a free & open-source invoice generator: - Live PDF preview - 100% client-side - No sign-up required - Includes a Stripe-style invoice template - Built with modern web tech – simple to self-host or fork Repo: https://github.com/VladSez/easy-invoice-pdf Demo: https://easyinvoicepdf.com Would love feedback, contributions, or ideas for other templates/features!

Seems to work well. The live preview workflow is nice. I like data URLs but not sure how other people feel handling several-hundred character URLs.

Only minor gripe is that the "support my work" popup is a bit aggressive.

I'm copying the Puppeteer / Playwright client API to run in a Chrome extension using the native Chrome extension APIs. It is possible to run Playwright inside a Chrome extension, however, it requires the Chrome DevTools Protocol (CDP) to automate a browser which really hurts the user experience, is very slow, and opens security vulnerabilities. Chrome extension APIs can accomplish maybe ~85% of the same functionality…

Cool concept, would you expect this to be compatible with Firefox/Safari as well? Safari in particular would be useful as it doesn't natively support Puppeteer/Playwright.

My roommate and I are still working on Tornyol, our mosquito killing drone! It uses ultrasonic sonar to detect mosquitoes, and missile control theory to ram into mosquitoes and grind them in its propellers. Our target platform is a 40 grams tinywhoop so it’s safe to fly everywhere and makes almost no noise :). A Roomba for mosquitoes! The main plus compared to traditional systems is that a drone can cover an enormous…

Duuuude! Give me this. Please. We have these mosquito bats/racquets that I've to use every day in a futile attempt to keep my family safe. I need something like what you're building. I looked up even laser mosquito killers.

Do LLM Agents really understand Linux?.

I am working on world model for computer systems. I am designing experiment and benchmark for LLM Agents to see if they possess understanding of "Linux". World model for computer systems will be crucial next step for computer use agents to reliably plan their actions over long horizon.

I often need a PostgreSQL server for testing an application, vibe coding, or troubleshooting a PG client. Inspired by Neon's architecture, I implemented PostgreSQL WASM (PGlite) with a cloud proxy (via Websockets) at https://postgresql.dbfor.dev All the PostgreSQL data lives in your browser, and you have unlimited PostgreSQL servers that persist the data locally without installing anything.

This is very cool.

Currently thinking about better ways to spread the word about https://theretowhere.com (my website that makes it easier to find apartments and Airbnbs/hotels close to things you care about).

I've actually started getting some back and fourth feedback with a couple users, which has kept me motivated and validated. But I need more organic traffic somehow. I've recently released a new usecase (https://theretowhere.com/vacation) that might be more well suited for vacationers, so let's see if that sticks.

Funny anecdote from today - I just set up Slack notifications so I get more instant knowledge of errors on the platform, and the first notification came in just a couple moments after I deployed. It was for an error that I thought noone would run into for a couple days. Imagine my (bad) luck!

I just discovered the formulas Excel library for Python, and I have about two dozen ideas for things that you could do with it. It turns out they already implemented the first dozen in the library itself, but the possibilities that come from extracting the computational graph out of a workbook are huge.

What ideas haven't been implemented that you're going to work on?
