I created these custom feeds for myself, because I wanted to stop doom-scrolling. I also love swiftlang and wanted a weekend project ✅

But I guess you can use them too... but only a little, as a treat. 👀

Find these links in the Feeds tab on my profile. And you enjoy them? Like and share further 🔗

Are those servers also written in Swift? 👀

🙏 I'm especially looking for help identifying off-topic folks - those that aren't about the Swift language, but about other uses of the word, like the singer, the financial system, etc.

If you see an off-topic post in the swiftlang feed, please click the three dots -> "Show less like this". Thanks!

Honza Dvorsky @czechboy0.dev · 15h

If you're using my swiftlang feeds, you can now provide feedback right through Bluesky!

Tap the three dots next to the post and select "Show more like this" or "Show less like this".

Your feedback will help me improve the automatic filtering.

Thanks! 🙏 #swiftlang

This is the API that the Bluesky client calls on the feed: docs.bsky.app/docs/api/app...

Most clients do send a JWT token, which includes the user id, so it is tied to a user, but I only look at the aggregated number of 👍 vs 👎 per post.

Same way as custom labeler services work on Bluesky.

Hmm I'm glad I'm not invested in AI infra companies, the math really isn't adding up. At this pace, when will they be profitable?

If I believed in rational markets I'd even short them, but I don't, so I won't 🫢

And I sure hope they never get bailed out with gov't funds.

Good question, solve a problem you have. I didn't find it easy to follow swiftlang content on bluesky, so I built a custom feed using Swift 🙂

Gluing data from several APIs behind one nice API is also pretty common, allows you to then build a simple CLI/app also in Swift.

Kind of exhausted and excited at the same time, winding down for the flight home from @serversideswift.info conference. A stellar #swiftlang community sharing & new voices adding into the mix this year.

@0xtim.bsky.social and Daniel Steinberg did such a wonderful job guiding the sessions!
