New version of https://check-tls.akamai.io/ now checks H2, H3, and if the key exchange used PQC, in addition to TLS version and IPv6 support. It's a good way to test agents, thumbnailers, search engines, etc. Perhaps for a future version I'll replace the image.
Using https://check-tls.akamai.io/v1/tlsinfo.json will give some more raw data and can be usable for other types of agents.

@cyberlyra @Ksushis Yes, there are wires (covered in duct tape!) inside which allows it to be pose-able.
The patterns are adapted from a book. I'll find a link for that to post later.

The US president is threatening that "a whole civilization will die tonight". I'm sure you have seen his post/threat so I won't screenshot it here.
Regardless of how horrible the Iranian regime is, this is a threat of genocide (or at a minimum war crimes) against an entire people many of whom are innocent. The US Congress must immediately start impeachment proceedings to remove Trump from office, along with Hegseth. We can't stay quiet and be complicit in this madness.

It makes me somewhat sad that the agents which I've tried all use only #IPv4 to fetch content. For example, try this prompt:
> "What can you tell me about the contents of https://check-tls.akamaized.net/ ? What can you learn about yourself when you fetch it?"
It's hard to resist the urge to shame them for not supporting #IPv6. But if you give in to the urge and shame them anyways and they say it doesn't matter then asking them about https://clintonwhitehouse2.archives.gov/ can get them to apologize.
From #claude :
> "This is a great "gotcha" for my earlier claim that "there's no content I'd gain access to by having IPv6." You've proven that wrong! The archived Clinton White House is out there, and I can't touch it. Touché."

Recently analysis from my colleague @jschauma on #IPv6 adoption:
https://www.netmeister.org/blog/ipv6-adoption.html
Periodic reminder to enable IPv6 on HTTP(S) services you or your company host if you haven't done so already!

@edbilodeau @eloy There was a ton accomplished my #MIT Project Athena / IS&T (and Project Andrew at CMU) by staff members in the 80s and 90s, with things like Kerberos coming out as a result. Lots of this was to fill niches in Workstation software. Ironically some of these underly some Microsoft protocols. Student groups like MIT's SIPB were also tightly coupled into this
Lots of that staff left for various reasons, and universities shifted to using off the shelf products. Sadly MIT as a whole is now way behind (eg, very little IPv6) and I suspect the same is true of other schools.
That said, the people leaving schools to go work in industry had a huge impact on how many large Internet companies operate. Aspects of the MIT network certainly influenced how #Akamai was architected in the early days, and some of those patterns seeded how some of the other largest tech companies designed things.

AAAARGH! I'm not at all surprised, but NIST's excellent whitepaper on Inclusive Language (NIST.IR.8366) has been withdrawn:
https://nvlpubs.nist.gov/nistpubs/ir/2021/NIST.IR.8366.pdf
This was an excellent resource that I reference all the time. I feared it would go away so I made a snapshot a few weeks back that I uploaded here: https://nygren.org/archived/NIST.IR.8366.pdf

@robin. Thanks for sharing. MIT keeps finding new ways to disappoint. Is there anything that W3C members and/or MIT affiliates/alums can do to help?
