  • What do you want the UI for? For configuration it’s usually meh because it’s the kind of thing you configure by config file, often generated config files even. For stats it’s where it gets interesting, usually third-party options like Grafana is used along with something like Prometheus to collect the metrics.

    When it comes to easy configuration, newer options go for the zero configuration angle rather than a nice UI to configure it. Just need some Docker tags and Traefik automagically configures itself, so the UI is just for viewing information.



  • Few of them for most use cases, especially a VPS. My server have a couple of IPs each mapping to a different VM, they can all claim 22/80/443 as you’d expect, but that’s just basically the same as having a bunch of VPSes anyway.

    It’s useful for some other uses like, I might want to dedicate an IP for VPN exit that doesn’t expose any services.

    Another use is sometimes you just want two things to stay entirely separate, even if on a technical level it could work with a reverse proxy. It can eliminate some class of exploits like request smuggling.

    One use case I’ve had for a customer is they have a system that can only do TLSv1.0, which is wildly obsolete and exploitable. So that particular API endpoint was served from a secondary IP, that way I can continue to enforce TLSv1.2+ on the primary IP. It’s possible with some reverse proxy magic with HAproxy, but I could also just make a new server block in the existing NGINX bound to that IP and call it a day.


  • The performance is a good point. You can do the striped mirror with ZFS too and still get the advantages of ZFS.

    I think you can do all of that through the Proxmox UI, but it shouldn’t be too hard to do on the CLI either. You just make two mirror sets and you’re good to go. ZFS should automatically distribute the load across the two mirrors.






  • You can return multiple A/AAAA records for the root, the TLD delegates the whole thing to your nameservers and it’s free to return whatever you want. Registrars actually do let you set records on the TLD’s zone, it’s called glue records and they’re typically used to solve the nameserver chicken and egg problem where you might want to be your own nameservers. Mine’s set that way:

    ~ $ drill NS max-p.me
    ;; ->>HEADER<<- opcode: QUERY, rcode: NOERROR, id: 32318
    ;; flags: qr rd ra ; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0
    ;; QUESTION SECTION:
    ;; max-p.me.    IN      NS
    
    ;; ANSWER SECTION:
    max-p.me.       3600    IN      NS      ns2.max-p.me.
    max-p.me.       3600    IN      NS      ns1.max-p.me.
    

    The me registrar will give you the IP for those two so you can then ask my server for where max-p.me really is.

    The bigger issue is usually there’s a bunch of stuff under your root domain like MX records, TXT records, potentially subdomains. That’s a huge problem if you need to CNAME the root to a hosting provider, as the CNAME will forward the entire domain including MX and TXT records. Cloudflare sort of works around that with server side flattening of CNAMEs, but that’s not standard. But if you have a www subdomain, then it’s a complete non-issue. And really, do you want to delegate your MX records to WP Engine?

    The main reason people went without the www is the good old “it looks cooler and shorter” while ignoring all the technical challenges its brings, and that’s probably why browsers now hide the www so that website designers don’t have to do this atrocity.


  • want someone to prove his LLM can be as insightful and accurate as paid one.

    The full DeepSeek model is available for download, and should generate about the same quality answers as the official one, with the bonus of less censorship. I pretty trivially got it to talk about the Tiananmen Square, and they can’t even ban me for it.

    That said, that’s rarely the point. It’s usually because you can, a cost saving measure, sometimes you plainly just don’t need a good model, sometimes you want privacy, sometimes you need privacy at the cost of quality.

    If your business is shoving customer reviews into a model, you really don’t need the best model for it to tell you how angry the customer is.

    Personally I just do it for fun and because I can. Sometimes you just do things for no other reason than because you can.
