r/RedditAlternatives is another one that might be worth mentioning instances on.

One of the founders of Ferrous Systems has answered some questions about it on Hacker News. See here and here.

The spec they created for the certification process is open source. There is some “tiny” amount of the patches that aren’t public but it sounds like it is essentially a recent stable release of Rust because the other major changes have been contributed upstream. It’s not clear if they definitely plan to eventually release the rest of thier changes as open source or not but they will consider it.

I recommend Waistline if you use Android. It’s on F-Droid.

The barcode scanner uses a community run database (Open Food Facts) for nutrition facts so you might find that you need to manually input items or correct outdated info more often than compared to the more popular My Fitness Pal. Obviously that gets easier once you build up a collection of your usual foods in the app.

They provide games to claim each week as part of the paid Amazon Prime subscription. So they are “free” if you already have another reason to have Prime.

I think you can edit your post on Lemmy to correct it.

Not enough people know about that very useful website. Although I think that Lemmy should have this kind of complete search as a native feature without needing to go to a third party website.

Yes, posting and interacting is essential to help our communities grow. I used to only lurk but have been trying to post more on here.

A big sore spot is that youtube videos and text posts can’t open in-line on the front page.

I see a book icon under posts that does this when browsing through my instance’s website. Most of the mobile apps are early in development and may not have this feature yet though.
