WebPKI is derived from X.509, but I don't think X.509 lives on anymore. X.500 was stripped down to form LDAP, which is still in very heavy use today. There's still some X.400 systems in existence.

X.500 was stripped down to form LDAP No, LDAP was a student project from UMich that somehow gained mindshare because (a) it wasn't ISO, and (b) it cleverly had an 'L' in front of it. It's now more complex and heavyweight than the original DAP, but people think it isn't because of that original clever bit of marketing.

The physical usps works because, the usps controls every inbox and every outbox; everyone has to have an inbox/outbox with the single carrier, and no one can actually reject or refuse mail. All the downsides of iMessage but the government reading your email bc it's not an encrypted protocol. Spam exists in the real world, this wouldn't have worked either

#163I wish someone would write some RFCs and e-mail could get an update.

There's an entire book devoted to ripping up the OSI model: https://docs.google.com/document/d/1iL0fYmMmariFoSvLd9U5nPVH...

#165>> SMTP "“didn’t win because it was ‘better,’” he argued, but “just because it was easier to implement." Yes - and this is actually really important!

Maybe X.500 - also known as LDAP, and widely deployed across enterprises in the form of Active Directory.

note that it was 'tolerable latency without echo cancellation in France', most other places had long enough latency anyways that they needed to have it anyways. and of course now everything needs echo cancellation. I think standards are important, and I'm sad that no one bothers anymore, but stuff like this and the inclusion of interlace in digital video for that little 3 year window when it might have mattered does…
I'd forgotten about the French connection here. BTW, I searched Kagi for "tolerable latency without echo cancellation in France" and saw your comment. Wow. I didn't realize web crawlers were that current these days.

> Ethernet had to adapt to deterministic real-time needs Without being able to get too into the telco detail, I think the lesson was that hard realtime is both much harder to achieve and not actually needed . People will happily chat over nondeterministic Zoom and Discord. It's both psychological and slightly paradoxical. Once you let go of saying "the system MUST GUARANTEE this property", you get a much cheaper, bet…
> not actually needed What you need is more that enough bandwidth . Think of the difference between a highway with few cars versus a highway filled to the brim with cars. In the latter case traffic slows to a crawl even for ambulances. It seems like it was just cheaper and easier to build more bandwidth than it was to add traffic priority handling to internet connectivity.
That was a selling point, because "hey we guarantee this circuit" but it was also very expensive and labor intensive
Where just dumping your bits into the internet and letting the network figure it out outsourced a lot of that complexity to every hop along the network you didn't own. But, because they care about their networks everyone would (in theory) make sure each hop was healthy, so you didn't need to hand hold your circuit or route completely end to end

The USPS is paid by spammers to ensure delivery of their physical spam. You doing think they wouldn't have also accepted payment from spammers to ensure delivery of their internet spam?
