Project mention: Restore full BambuNetwork support for Bambu Lab printers | news.ycombinator.com | 2026-05-12
And yet, I'm using Molly, an independent Android fork of Signal.
Signal itself is released on AGPL-3.0: https://github.com/signalapp/Signal-Android so this is probably why Molly forked.
So not sure what are you talking about.

Project mention: OpenScreen is an open-source alternative to Screen Studio | news.ycombinator.com | 2026-03-31
I used ScreenStudio for a year. Then, when my annual subscription was up for renewal I tried https://cap.so/ and https://screensage.pro/
After experiencing many bugs and UX oddities with both of those, I went back to ScreenStudio.
ScreenStudio is reliable and produces the best results for my use case (educational content and client updates)

Project mention: Ask HN: What Toolchains Are People Using for Desktop App Development in 2025? | news.ycombinator.com | 2025-08-09
Because I mainly work with python, I am using Kivy (https://kivy.org/).
Earlier I was HTMX, Jinja templates, Flask, Tailwind and little vanilla JS. It was too inelegant for my taste.
I am considering moving to either Swift, or JS/Svelete

activitywatch
The best free and open-source automated time tracker. Cross-platform, extensible, privacy-focused.
Project mention: EFF Launches Age Verification Hub as Resource Against Misguided Laws | news.ycombinator.com | 2025-12-11Ah okay. I think this would probably be pretty tricky, security-wise, no? One of my first thoughts that might help would be writing a simple tool that parses history from your browsers to categorize it. Other than that, there are things like https://activitywatch.net/ (which seems to have a desktop and Android version)
