  • Additionally, there’s the usability hurdle of interacting with non-home instances from outside mastodon. If I pull up someone’s blog and click the little mastodon social media icon, it may very well link to mastodon.world. If my home instance is mastodon.social, now I have to launch into my own server, search up the account, and then begin interacting.

    It’s trivial to do but it is an extra step, but for your less-tech-literate friends and family it can be a point of confusion. Mastodon handles federation great in-ecosystem, but the broader web is still going to treat each instance as a different site.




  • Sticking two E2EE tunnels together with a plaintext middleman doesn’t result in a single E2EE tunnel.

    The reason the distinction is important is because the security profile is vastly different—a compromised server leads to a compromised message—which isn’t true for actual E2EE services like a pure Matrix link.

    Side note: the first thing you should ask of a “end-to-end encrypted” product to you is “which ‘ends’ do you mean?” I’ve seen TLS advertised as E2EE before.



  • I have seen you comment in several comment chains. Please just understand that there is risk even if by the letter of the law everything is legal. There are plenty of cases with copyright / fair use where very expensive and long lawsuits were made against parties who did nothing illegal.

    LW mods are clearly not comfortable with the risk with their current situation. Respect that, and don’t expect them to take risks beyond their comfort on your behalf. If you want someone who is willing to serve you content at that level of risk, you can create an account with one of the other communities.



  • Amdahl’s isn’t the only scaling law in the books.

    Gustafson’s scaling law looks at how the hypothetical maximum work a computer could perform scales with parallelism—idea being for certain tasks like simulations (or, to your point, even consumer devices to some extent) which can scale to fully utilize, this is a real improvement.

    Amdahl’s takes a fixed program, considers what portion is parallelizable, and tells you the speed up from additional parallelism in your hardware.

    One tells you how much a processor might do, the only tells you how fast a program might run. Neither is wrong, but both are incomplete picture of the colloquial “performance” of a modern device.

    Amdahl’s is the one you find emphasized by a Comp Arch 101 course, because it corrects the intuitive error of assuming you can double the cores and get half the runtime. I only encountered Gustafson’s law in a high performance architecture course, and it really only holds for certain types of workloads.
