You kind of can though. You serve cached assets and then use JavaScript to modify it for the individual user. The specific user actions can't be cached, but the rest of it can.

The "can't" comes from the fact that VLC is not going to rewrite their forum software or software forge. Software written in PHP is in most cases frankly still abysmally slow and inefficient. Wordpress runs like 70% of the web and you can really feel it from the 1500ms+ TFFB most sites have. PhpBB is not much better. Pathetic throughput at best and it has not gotten better in decades now. I don't know how GitLab beca…

At least phpBB died 15 years ago with most communities migrating to Xenforo. I'm not quite sure how or why WP is still around with so many SSGs and SaaS site builders floating around these days.

With the first RVA23 boards shipping this month, I find it a mistake to still focus on legacy ISAs like x86 or ARM rather than what will be dominant by the time AV2 is deployed.

riscv is primarily used in microcontroller or peripheral cores on an soc. It'll be a while yet until it is competitive on application cores that applications people run on such that we adopt it in mass. Arm and x86 are also not legacy or going away. The choice to focus on them is rational at this time.

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.

There situation is more intricate: the allegations are that Snapchat infringes patents through its use of the AV1 and HEVC codecs. Dolby states that it did not participate in AV1’s development and made no FRAND commitment with respect to AV1, and that its HEVC FRAND obligations apply only to decoding, not encoding.

> If people truly wanted memory safe encoders/decoders Really? How many codecs have your neighbors contributed money for the development of, just curious.

I think these conversations are directed by the parties funding the efforts. Example: "we (large company) want a fast AV2 decoder" -> they pay a specialized team to do it -> this team works in C for the most part, so it is done in C. If there were financial incentives to do it in Rust, they'd pay more for a Rust decoder.

I'm more interested in the idea of general "people" (the commons) funding complex video encoders. I do wish that was the world we lived in, however :)

AV2 video codec delivers 30% lower bitrate than AV1, final spec due in late 2025 (videocardz.com) | Oct 2025 | 277 points | 223 comments | https://news.ycombinator.com/item?id=45547537

I care much less about bitrates than about hopefully finally settling on one series of "standards". It looks like H.266 is dead in the water (I haven't even heard of it existing) so we might finally settle on AV2 as "the" new standard, rather than having the infight with half of hard/software only supporting either the state-of-the-art codec from the H26x or the AVx series...

Don’t worry, hardware manufacturers are going to keep ripping us off with HDR encoding. HDR10, HDR10+, Dolby Vision, and so on.

I hear you, I disagree.

We do not need to argue over this, but rather, we can see what happens over the next couple years.

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?

You've gotten several comprehensive responses so far and I want to add a niche corner that people might assume might not have the bot problem but still does. I run a website that hosts tools for my family: games and a TV interface for the kids, remote access to our family cloud and cameras, etc. Sensitive things require log in and have additional parameters required for access of course. I specifically blocked bots f…

If your site uses https, they could also get your domain from the certificate transparency logs for the certificate you use.

Thank you for describing the tragedy of the commons

The commons were never unregulated. This is a tragedy of enclosure. https://en.wikipedia.org/wiki/Enclosure

We might get stuck discussing semantics. Large parts of the internet remain public and open; but an incredibly vast part of it is a toxic wasteland.

It’s true that many spaces people frequent are ‘enclosed’, but these are also less subject to the abuse taking place in the public and open areas.
