  • It’s a bit unconventional maybe, but I vote simple-nixos-mailserver - IF you are curious / willing to learn nix. It’s essentially just sanely configured dovecot, postfix, rspamd.

    My config for those three combined is about 15 lines, and I have never had an issue with them. Slap on another 5-10 lines for Roundcube as a webmail client.

    Since it’s Nix, everything is declarative, so should SOMETHING happen to the server, you can be up and running again super quickly, with the exact same setup.



  • We expose about a dozen services to the open web. Haven’t bothered with something like Authentik yet, just strong passwords.

    We use a solid OPNSense Firewall config with rather fine-grained permissions to allow/forbid traffic to the respective VMs, between the VMs, between VMs and the NAS, and so on.

    We also have a wireguard tunnel to home for all the services that don’t need to be available on the internet publicly. That one also allows access to the management interface of the firewall.

    In OPNSense, you get quite good logging capabilities, should you suspect someone is trying to gain access, you’ll be able to read it from there.

    I am also considering setting up Prometheus and Grafana for all our services, which could point out some anomalies, though that would not be the main usecase.

    Lastly, I also have a server at a hoster for some stuff that is not practical to host at home. The hoster provided a very rudimentary firewall, so I’m using that to only open necessary ports, and then Fail2Ban to insta-ban IPs for a week on the first offense. Have also set it up so they get banned on Cloudflare’s side, so before another malicious request ever reaches me.

    Have not had any issues, ever.








  • Fuck Amazon, fuck Alexa.

    But that wall clock is glorious. It’s a decently look clock, but seeing how much time you have left on multiple timers with a single glance is so incredibly useful. Especially when you’re cooking.

    I’m currently in the process of migrating away from the shit Alexa ecosystem, but no matter what I end up with, I’ll have to find an alternative for this clock



  • For me personally, there is only two applications of LLMs in programming:

    • doing tasks I kinda know how to do, but don’t want to properly learn (recent example: generate pgf plots from csv data in matplotlib. 90% boilerplate, I last had to do it 3 years ago and vaguely remember some pitfalls so can steer the LLM in that direction. Will probably never again have to do this, so not worth the extra couple hours to properly learn
    • things I would ordinarily write a script for, but aren’t worth automating because they won’t come up in the future again (example: convert this Lua table to a Nix set)

    Essentially, one-off things that you know how to check for correctness.







  • IDK. They will certainly be fine here, on earth. Even if everything else goes to shit, they will continue living in luxury.

    On a spaceship / station / Mars colony though? As much as I love sci-fi, living there will be ROUGH, regardless of how rich you are.

    I think it’s more an ego thing: “I want to go down in history as the first human on another planet, lest I be forgotten” combined with an unhealthy dose of not giving a fuck about other people, which is kinda a prerequisite to being a billionaire in the first place.
