This niche of the field has come a very long way just over the last 12 months, and the tooling is so much better than it used to be. Trying to do this from scratch, beyond a "kinda sorta good enough for now" project, is a full-time engineering project in and of itself.
I'm a maintainer of Opik, but you have plenty of options in the space these days for whatever your particular needs are: https://github.com/comet-ml/opik
Alternatives to Opik include Braintrust (closed), Promptfoo (open, https://github.com/promptfoo/promptfoo) and Laminar (open, https://github.com/lmnr-ai/lmnr).
Note first that the piece is not about zacusca.net itself. It's saying 'You should go out of your way to build on a protocol. Even if the protocol is 'dead'. Perhaps I can clarify that.
Regarding Zacusca, I appreciate you explaining why it doesn't seem useful. First, it's not for everyone. Some people like reverse chron as an algorithm. Second, let me clarify how the pipeline works. But I think I explain the import/export poorly: - you export the feed addresses - you set up the categories - Zacusca continously polls the imported feeds, sorts them into the categories and exposes the categories as new feeds
So it's fire and forget. And you can keep your existing feeds as duplicates if you want.
Regarding copyright I believe that this is fair use. It lets individual readers print their subscriptions. It's indistinguishable from them using a printer at home, except that it's delivered automatically.
But yes it's a grey zone. It's making a copy of someone's copyrighted work without their permission. (Remember it was technically illegal to load songs onto your iPod.) And so that's why the book product (which brings together all posts from one publication) is for authors, since I think that strays more towards publishing rather than mere printouts.
Roo is less solid but better-integrated.
Hopefully I'll switch back soon.
