Maybe I’m naive about this, but I didn’t expect AI scrapers to be that big of a load? I mean, it’s not that they need to scrape the same at 1000+ QPS, and even then I wouldn’t expect them to download all media and images either? What am I missing that explains the gap between this and “constant DDoS” of the site?

Yes, it's that BIG of a load: https://status.sr.ht/issues/2025-03-17-git.sr.ht-llms/

Thanks. I imagine there is a (a) a lot of interest in scraping source code, and (b) many requests to forges hitting expensive paths. 99% of volume though, wow, much more than expected.

You cant really cache the dynamic content produced by the forges like Gitlab and, say, web forums like phpbb. So it means every request gets through the slow path. Media/JS is of course cached on the edge, so it's not an issue. Even when the amount of AI requests isnt that high - generally it's in hundreds per second tops for our services combined - that's still a load that causes issues for legitimate users/develope…

Thanks, appreciate the details. 99% is far above the amount I expected, and if it specifically hits hard to cache data then I can see how that brings a system to its knees.

maybe not great naming. Sounds very similar to the rapper D4vd, who was just arrested for murdering a 14 year old girl

Actually it's closer to https://youtube.com/@dave2d who is a popular tech YouTuber

That is what I thought of too. Almost live David is a popular name or something... /s

Nice.

What's the current state of of Dolby trying too attack AV1 ecosystem (Snapchat more specifically)? I hope there is an organized fight back by AOM against these trolls.

Project description: dav2d is the fastest AV2 decoder on all platforms :) Targeted to be small, portable and very fast. If you're out of the loop like me: AV2 is the next-generation video coding specification from the Alliance for Open Media (AOMedia). Building on the foundation of AV1, AV2 is engineered to provide superior compression efficiency, enabling high-quality video delivery at significantly lower bitrates.…

looks at if AV2 is dead in the water https://www.sisvel.com/insights/av2-is-coming-sisvel-is-prep... yep

Trolls will always be trolls. The need to fight them just shows the need to reform the garbage patent system to make sure no one can ever patent software.

It's just unfortunate. Like there was a pharmaceutical company named "Isis" that changed their name due to the association with the terrorist group. That said, while people will notice for the next couple of months, I don't think it warrants changing a name for.

More importantly there's a really good band named isis that probably has not benefitted from the Islamic state. (Ok, they disbanded in 2010, but still).

is there any understanding of how big of an improvment av2 will be over av1?

About 30% better compression than AV1 at equivalent quality. But it'll be a while before it's a good idea to use AV2 in your home media server. (AV1 is still not that broadly supported)

The people who write DSLs for video codec asm, or who claim that it's fine to use intrinsics or X higher-level language and it will still be fast enough to be usable, are simply wrong and have never been able to demonstrate otherwise. Having said that I do think you could write a DSL to generate safe performant asm for a video codec. Just not a platform-independent one. It would still have to be asm.

It sounds like your second statement contradicts your first. But also, WUFFS exists and it looks like the Google Chrome GIF decoder ships in it: https://github.com/google/wuffs

It does not contradict it, and also, a gif is not a video.

I see zero public evidence that they've filed any lawsuits against the members of AOM in any jurisdiction. I'm sure there's been a lot of threatening letters sent...

Yup. The Dolby/Disney vs Snapchat lawsuit is going to be the first one. So far it's only been filed. The big question is if AOMedia is going to make good on their Mutually Assured Destruction promise of using their patent and financial war chest to to countersue into oblivion anyone trying to go after AV1 adaptors.
