  • I think that at the bare minumum, the PORN<->GOV connection must not occur. How about this (simplified):

    • USER visits porn site
    • PORN site encrypts random nonce + “is this user 18?” with GOV pubkey
    • PORN forwards that to USER
    • USER forwards that to GOV, together with something authenticating themselves (need to have GOV account)
    • GOV knows user is requesting, but not what for
    • GOV checks: is user 18?, concats answer with random nonce from PORN, hashes that with known algo, signs the entire thing with its private signing key
    • GOV returns that to USER
    • USER forwards that to PORN
    • PORN is able to verify that whoever made the request to visit PORN is verified as older than 18 by singing key holder / GOV, by checking certificate chain, and gets freshness guarantee from random nonce
    • but PORN does not know anything about the user

    There’s probably glaring issues with this, this is just from the top of my head to solve the problem of “GOV should know nothing”.

  • Actual answer for 3:

    • put jellyfin behind a proper reverse proxy. Ideally on a separate host / hardware firewall, but nginx on the same host works fine as well.
    • create subdomain, let’s say sub.yourdomain.com
    • forward traffic, for that subdomain ONLY, to jellyfin in your reverse proxy config
    • tell your relatives to put sub.yourdomain.com into their jellyfin app

    All the fear-mongering about exposing jellyfin to the internet I have seen on here boils down to either

    • “port forwarding is a bad idea!!”, which yes, don’t do that. The above is not that. Or
    • “people / bots who know your IP can get jellyfin to work as a 1-bit oracle, telling you if a specific media file exists on your disk” which is a) not an indication for something illegal, and b) prevented by the described reverse proxy setup insofar as the bot needs to know the exact subdomain (and any worthwhile domain-provider will not let bots walk your DNS zone).

    (Not saying YOU say that; just preempting the usual folklore typically commented whenever someone suggests hosting jellyfin publicly accessible)



  • Neovim, because I wanted something that would not just disappear.

    I never really got along with VSCode, opting for Atom instead. Microsoft bought GitHub, which owned Atom, and promptly discontinued it.

    Nvim has such an active community (and no “owner”) that I’m certain that this won’t happen again. At the same time, the plugin system is so flexible that I’m also certain that I will never miss out on any shiny new features.

    Over the years, my config has matured, and is mine. The thought of going back to an editor, any editor, less flexible in its configuration than nvim is just… an absolute “no”.

    It’s a steep learning curve, but well worth it.









  • Iain M. Banks’ Culture.

    I’m deathly afraid of the day some big studio manages to buy the rights and produce a Hollywood version of the Culture. Mostly because it is very easy to flip through the Wikipedia entries and then take the superficial aesthetic of the Culture and misunderstand or ignore the rest.

    For an example on how easy it is to do this: I remember vividly when the German translations of the later books came out, and they all had some variation of

    The Culture is the galaxy-spanning empire of mankind. Unbeknownst to its citizens however, their supposedly benevolent machine gods are about to dispense with the needs for humans at all"

    in the blurb. Someone scanned the wiki page until they read something about “superhuman AI” or the like, then went “ah, got it, I’ve seen Terminator”.

    In a similar vein, I cannot imagine that Hollywood would portray the Culture as an unquestionably good Utopia. They’d not be able to resist to paint the luxury gay space communists as “…with a dark secret / actually dystopian /…” tones.
