Denon actually tend to play nicely with local control, with telnet, RS-232 serial, and local network APIs that are easy to use. My Denon receiver worked OOTB with Home Assistant.

This is also a problem in classical HPC, there aren't very many algorithms that can scale linearly with cores. That's partially why so many HPC algorithms tend to be built on matrix multiplication and Monte Carlo, because those do tend to scale near arbitrarily.

People may forget that Ethernet originally had a shared transmission medium and collisions were a serious limitation. Switching was a later addition that mostly solved collisions and really paved the way for Ethernet as we know it today.

Interestingly, early Ethernet performance studies suggested that about 37% utilisation was the best possible on a heavily contended network due to all the collisions. So a 10mbps Ethernet cable run was arguably similar in performance to 4mbps TR? That was essentially IBM's marketing argument for 4mbps token ring. But TR was more predictable under heavy traffic contention. That’s what we were told anyway…

Trivia: because IEEE 802.3 working group was formally in charge for standards of "local area networks with CSMA/CD", 1000BASE-T has half-duplex mode defined (which nobody implemented) as otherwise it would fall outside of working group purview.

I remember finding an old hub off in a far corner in 2008 working on my school’s network. It was a rare find then!

Hubs were still just barely still relevant when I first started learning networking, but it was late enough that I don't think I've ever encountered one in serious use. Especially after port mirroring became a common feature even on affordable switches. I think we had an old pile of industrial/scientific test equipment in grad school nobody wanted to touch that was using an old Cisco hub, but my memory is fuzzy.

I've definitely never seen any old Thicknet networks in use, though I have seen Token Ring in active use semi-recently. I never learned anything about Token Ring other than I remember old CompTIA mentioning it existed.

I do have a fondness for seeing this old tech that was way out of my reach or just barely too old to encounter back in the day being used, it's so neat to learn about. ClabRetro on YouTube is one of my few "drop everything and watch a new video" creators.

Back in 1999 I was still doing the crawling-under-desks thing. I was at a tobacco companies sales office... and they had a wallplate with ports labeled token ring, ethernet, and appletalk (looked rj11, so phonenet?). A year or two later I worked at their central location in Virginia in a warehouse decommisioning old equipement, got to see some FDDI and HIPPI hardware. Never saw it being used though.

And at my previous job, in a quite normal office, there was a wallplate labeled DEC with the weirdest jack I've ever seen. I couldn't visually identify it, and I thought I knew everything. 1.5" inches wide, with a plastic spring-loaded cover that came down from the top. Maybe only two conductors in it, not normal rj-style pins at all. I'd guess something Vax, but I thought those were always ethernet since the early 80s, and anything older still wouldn't likely have survived until 2025.

This reminded me of my first encounter with Thicknet (and thinnet) just a few years ago.

We'd never gone over it when I went to college in 2012 but come 2022, I found myself learning about it by pulling it out of the ceiling during a decluttering project.

Made some sense, though. Being a TV station, coaxial cable was probably very plentiful when it was installed. We saved a couple of the vampire clamps at the time just for laughs. I wonder if they're still in the office.

Hubs were pretty common when I went to college (2003-2007), but not for the school's infrastructure. They would lend them to students because the rooms only had a single network port. Not sure how long that use case lasted; I imagine by now renovations have happened and rooms have multiple network ports (and the dorms would have wireless in any case).

You were one generation before me, I started college in 2007. By then it was all those super cheap little 4 port Netgear switches most people reading this have probably owned at some point. I don't remember us having official dorm wifi but we were allowed to have our own wireless routers, probably an IT nightmare by today's standards. I recall we also all got publicly routable IP4s.

Hubs were valuable at our CS dept because you could sniff traffic easily with accurate timestamps

And still people use wi-fi...

GL.iNet is more open (they run an OpenWRT fork that they open source with a proprietary GUI on top). They have a beta for a mesh system on top of that: https://www.gl-inet.com/en-us/pages/mesh . I haven't tried the mesh, but I have had very good experiences with a few of their routers and they are what I recommend to friends.

Ubiquiti mesh stuff works very well and is an overall polished experience. Supposedly their APs are at least distantly descended from OpenWRT but they are not open source. Their platform is pretty open in terms of integrating with other stuff and not locking you in, at least.

See ntopng, it provides a nice monitoring UI for exactly this type of scenario. It's higher level than Wireshark, more focused on high level traffic analysis.

Going to check this out.

I have a Studio 2 for work and even on windows it runs like absolute garbage. Almost unbelievably slow at everything and locks up frequently. Maybe I have a dud with some sort subtle hardware fault but it's by far the worst computer I've owned. Not a good look for a premium priced laptop that is supposed to be a showcase for Microsoft.

And yeah, can't run Linux on it either to try and salvage it because of all the weird and undocumented hardware.

SELinux was originally designed by the NSA to serve their needs, which are probably a bit more intense than "normal" users, and that was over 25 years ago. I'm not convinced a fresh effort couldn't do better, though I'm more skeptical that anyone is willing to invest the resources.

The Russians did, with Astra Linux. They didn't do better

PfSense and OPNsense both support Tailscale and can integrate it with their normal routing/firewall behavior. I think OpenWRT can as well but I haven't tried it.

I think those do it by running official tsilscale client.

To get other tsnet clients to connect to non-tsnet client you need to provide the connection configuration through netmap from coordinator server

They do use the official client, but it also makes it fairly easy to bridge tailscale networks with regular wireguard clients with normal routing rules.

Then, a few months later x.ai announces a new SOTA frontier model, FeetGrok.

They'd use it for AI training purposes <:S

The prospect of going to a website I've never visited before, getting a captcha, and it saying "we don't think those are YOUR feet, access denied" is a little TOO believable.

25 years is the standard time horizon for automatic declassification, and someone high up probably decided to collect things together to publicize in an attempt to score some political kudos.
