  • Skype won’t be supporting anything at all very soon.

    What happened with Vonage is something that could happen with any kind of instant messaging, including things like Discord.

    With everything directly addressable (not just static addresses, but directly addressable), an IM/VoIP service can simply connect to the recipient. No servers are necessary in between, only routers. That doesn’t work with NAT (CG or otherwise), so what you have to do is create a server that everyone connects into, and then that forwards messages to the endpoint. This is:

    • More expensive to operate
    • Less reliable
    • Slower
    • A point for NSA eavesdropping (which almost certainly happened)

    This is largely invisible to end users until free services get enshittified or something goes wrong.

    Yes, it’s only tangentially related to static addresses, but it’s all part of the package. This is not the Internet we should have had.

    And at least in the US (in single family homes) its crazy unlikely that your router is behind any NAT

    Your router has NAT. That’s the problem. CGNAT is another problem. My C&C: Generals issues did not have CGNAT.


  • . . . nobody at home actually runs VOIP . . .

    Plenty of people used Skype and Vonage. Both were subverted because they have to assume NAT is there.

    . . . quick game servers don’t need static . . .

    But they do work better without NAT. That’s somewhat separate from static addresses.

    My old roommate and I had tons of problems back in the day when we tried to host an Internet game of C&C: Generals behind the same NAT. I couldn’t connect to him. He couldn’t connect to me. We could connect to each other but nobody outside could. It’s a real problem that’s only been “solved” because a lot of games have moved to publisher-hosted servers. Which has its own issues with longevity.




  • “Hashed emails”. Besides the fact that they can match up a hash from one source to a hash from another source to link them to the same person (they never said they’d salt them), emails often have enough predictability to break the hash. Assuming they all end in “@gmail.com”, “@outlook.com”, or “@yahoo.com” will get you the vast majority of emails out there. Unlike a good password scheme, people don’t shove a lot of random data into their email addresses.


  • The US is allergic to it, but needs to get over it.

    Aluminum wire was tried in the 1970s due to a spike in copper prices. The problem was that they just tried to swap it right in. Aluminum and copper have different rates of expansion. Over time, that would slowly loosen the connectors, and the wires would pop right out and cause a fire.

    You can design connectors to handle both, and you’ll see many electrical things today specify that they’re good for aluminum or copper wire. It still has a bad reputation among electricians; they haven’t unlearned the problem yet.

    Now, one place it’s more of a problem is in things like transformer windings. There are kilometers of wiring in any of them, so the higher resistance of aluminum is a problem.



  • There’s a thread of thought that pops up in pro-AI posters from time to time: technology can’t go backwards. The implication being that the current state of AI can only improve, and is here to stay.

    This is wrong. Companies are spending multitudes of piles of cash to make AI work, and they could easily take their ball and go home. Extending copyright over the training data would likely trigger that, by the industry’s own admission.

    No, self-hosted models are not going to change this. A bunch of people running around with their own little agents aren’t going to sustain a mass market phenomenon. You’re not going to have integration in Windows or VisualStudio or the top of Google search results. You’re not going to have people posting many pics on Facebook of Godzilla doing silly things.

    The tech can go backwards, and we’re likely to see it.
