Project mention: I'm recomming my customers switch to Linux rather that Upgrade to Windows 11 | news.ycombinator.com | 2025-10-15Not really.
On linux, you have OpenSCAD (which is okay for some applications) and you have FreeCAD (which sucks imo). Right now, I just use OnShape which works in my web browser and is similar to SOLIDWORKS.
In the future I will try running windows CAD under linux using kvm and this: https://github.com/casualsnek/cassowary

Project mention: Android 17 is the first since 3.x to add new APIs without releasing to the AOSP | news.ycombinator.com | 2026-09-18
https://en.wikipedia.org/wiki/Apache_OpenOffice
Difficulties maintaining a sufficient number of contributors to keep the project viable have persisted for several years. In January 2015, the project reported a lack of active developers and code contributions.[49] There have been continual problems providing timely fixes to security vulnerabilities since 2015.[50][51][52][53] In September 2016, OpenOffice's project management committee chair Dennis Hamilton began a discussion of possibly discontinuing the project, after the Apache board had put them on monthly reporting due to the project's ongoing problems handling security issues.[54][55][56]
Sounds like AOO is effectively dead, so this example is a fail to my challenge.
OpenSearch & ElasticSearch both seem alive, as well as OC & NC.
Neither https://github.com/privacyidea/privacyidea or https://github.com/eduMFA/eduMFA say either is a fork of the other.
I think you failed to share 3, 2 seem to valid examples of my challenge but the other 2 are questionable.

Project mention: New repository settings for configuring pull request access | news.ycombinator.com | 2026-10-08
I hadn't heard, but you're right. And they've clearly taken account of the negative impact a particular group was having on the ecosystem.
From the FAQ on https://hacktoberfest.com/ :
> Do I still submit pull requests to earn swag?
> Pull requests and merge requests will no longer count toward Hacktoberfest rewards. It’s easier than ever to submit low-effort spam PRs to projects, so we’re listening to maintainer feedback and no longer actively incentivizing PRs. That being said, we certainly still encourage you to work on open source and share your work with the world during Hacktoberfest. Our new format focuses on learning and building together while reducing the burden of low-effort contributions on maintainers.

Project mention: I Stopped Paying for Subtitle Services After Running Whisper in a Browser Tab | dev.to | 2026-04-28
For professional broadcast work, you'll still want human review. But for social media, internal videos, educational content, and quick drafts, browser-based Whisper is genuinely good enough.
