The ActivityPub protocol lemmy uses is (in my opinion) really bad wrt scalability. For example, if you press one upvote, your instance has to make 3000 HTTP requests (one to every instance that cares).

But on the other hand, I recently rewrote the federation queue. Looking at reddit, it has around 100 actions per second. The new queue should be able to handle that amount of requests, and PostgreSQL can handle it (the incoming side) as well.

The problem right now is more that people running instances don't have infinite money, so even if you could in theory host hundreds of millions of users most instances are limited by having a budget of 10-100$ per month.

I agree that it's not ideal to be hosted on a platform controlled by Microsoft, but it's just a fact that you lose 90+% of contributors if you are anywhere else (there's an article where someone compared, can't find it right now). It's not great that that's how it is, but you need to choose your battles.

I'm not really very concerned, since git itself is decentralized, and if Github starts causing visible problems moving somewhere else is not a huge problem. Also VPNs exist.

Interoperability is great, but sadly there isn't really any organized group effort to standardize more aspects / extensions of ActivityPub. AP is really "thin" in that it barely prescribes anything. There's not even a test suite to test whether software complies to the spec of AP.

So everyone kind of does their own thing, and fixes interoperability on a case-by-case basis. This makes it kinda frustrating to spend time on - lemmy already has special cases for many different softwares (peertube, mastodon, ...) and every one increases the complexity.

Lemmy is somewhat protected by being an AGPL-licensed project, preventing proprietarization. If there's ever a relicensing effort, ba fearful.

I'm not sure what exactly becoming a organization would entail, but so far I'd say the development part is not really large enough? For me I would start being suspicious when a significant amount of dev power came from compan(ies), but so far no company has shown any interest afaik.

There's already been a few forks, for example lemmynsfw has made some changes on their side, which nutomic is now looking to integrate back into lemmy.

There is a ton of decentralized projects that no one has really ever heard of, new ones pop up all the time (I was watching multiple of them in the past). Sadly in most cases it seems like most authors stop working on their projects after a while.

The same ideas have existed for a long time but both decade old projects (ever heard of Freenet? Probably no) and new ones . Many of them are very ambitious and try to replace huge swaths of things (not just file storage but also social aspects, web of trust, etc) but then collapse under the complexity. IPFS is the most well known new project and (good imo) has limited its scope, but sadly (still) suffers from huge scalability issues, some of which are deep in the design.

I think it's really hard to align incentives there - the nicer it is the harder it is to make money with it. So either these projects tend towards control by one entity or they tend towards death.

Really the only one that seems to have a long lasting life so far is torrents. Which are amazing. And Email if you want to count that.

I think flairs would be the same as user-tagging. There's an open proposal for post-tagging https://github.com/LemmyNet/rfcs/pull/4 and the discussion there was so far to add tagging for one type of thing and then later expand to others (like user tagging).

It's a bit of a complicated feature because it needs decision who can tag whom, and what is the scope (who is it federated two), and how does it transfer / interact with other ActivityPub software.

Personally I came with them so I guess they are my people ;)

0.19 was a bit of a special case because there was a set of breaking updates that had to be done at some point, and trickle releasing breaking changes isn't really great either. Usually hopefully the breaking changes are rare, so releases can be more frequent.

I don't think we found any specific groups of people attacking Lemmy. I personally just saw one or two what looked like individuals trying (and succeeding) to take Lemmy down with a few very simple requests that forced Lemmy to do lots of compute (something like fetching the next million posts from page 10000). The fixes for those were simple because it was just missing limits checking.

I'm not sure if there actually was a larger organized attack. Lots of performance issues in Lemmy simply appeared simultaneously and compunded each other with a rapidly growing number of active users and posts.

That is exactly what's happening :) better quantization matrix results in 25% smaller files with the same perception-based q which makes webp kinda useless often https://siipo.la/blog/is-webp-really-better-than-jpeg

Try jpeg-xl though. it's amazing.

I want to clarify that most/ a lot of the DB work of this release actually came from others e.g. nutomic, RocketDerp, Sh4d ;)

server load is too low, everyone upvote more stuff so i can optimize more

edit: guess there is some more work to be done 😁
