We had to set it up on the parts of VideoLAN infra so the service would remain usable. Otherwise it was under a constant DDoS by the AI bots.

I highly doubt there is no other technically feasible option to block the AI bots. You end up blocking not just bots, but many humans too. When I clicked on the link and the bot block came up, I just clicked back. I think HN posts should have warnings when the site blocks you from seeing it until you somehow, maybe, prove you are human.

I'm all ears on how we can fix it otherwise.

Keep in mind that those kinds of services: - should not be MITMed by CDNs - are generally ran by volunteers with zero budget, money and time-wise

I'm sure there are many solutions for many problems, but expecting a small Foss development team to know or implement them all is rather unreasonable.

I think the world gains more if the VLAN team focuses on their amazing, free contribution to the world, than if they spend the same time trying to figure out how to save you two clicks.

We all hate that this is happening, but you don't need to attack everyone that is unfortunately caught up in it.

If you have discovered such an option, you could get very wealthy: minimizing friction for humans in e-commerce is valuable. If you're a drive-by critic not vested in the project, then yours is an instance of talk being cheap.

Not on topic, but wow the internet has very quickly devolved into: click -> "making sure you're not a bot", click -> "making sure you're a human", click -> "COOKIES COOKIES COOKIES", click -> "cloudflare something something"

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?

It was above-fold on the BBC news website[0][1] several times over the past couple of months.

off topic, but related to the recent github alternative discussion:

Wow, this gitlab instance looked so much cleaner/simpler and less clunky than my past experiences! Also loaded really fast on first page load as well as subsequent actions

They've done the same thing with AV1, and I can't see that having prevented adoption, nor can I imagine Sisvel wanting to poke the bear that is AOMedia unless they're certain their case is absolutely watertight.

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.

While I do sympathetize with the AI DDoS situation, it'd be nice if there were a solution that allows them to work so they can pull official docs.

For instance, MCP, static sites that are easy to scale, a cache in front of a dynamic site engine

What are you even implying?

That codecs should be written in safer languages given that they usually process untrusted files. There have been a number of serious hacks from file parsing bugs due to them being written in unsafe languages. There's literally a DSL designed for this purpose (Wuffs) so it would be interesting to hear why they didn't use it.

There's an order of magnitude difference in speed requirements between file format parsing and image decoding, then another order of magnitude difference to video decoding. Even rav1d reuses dav1d's assembly (most of the actual runtime) to approach its speed.
