  • It depends on your overall energy use but generally that would be negligible when compared to heating and hot water, especially during winter when the furnace runs 24/7.

    In particular, during the winter, all excess energy from the oven is heat the furnace doesn’t have to provide so it’s basically free: you’d use that energy anyway.

    Generally the economy of scale should technically favor the prebaked bread, at least before the store slaps its value added surcharge for it. The store still needs to pay for the energy (but probably gets it cheaper than you), but also needs to pay to maintain a factory, equipment, employees. So you kinda need to factor in the price of your oven too and its wear and tear.

    I just buy the loaf because one thing I know for sure is if I factor in the value of my time, it’s way better and easier to work an hour than spend an hour baking a loaf of bread. The time to bake the bread costs more than if I used that time to work the equivalent time and buy 5 loaves of bread with the money.


  • 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.

    I’d probably do RAID-Z with ZFS rather than RAID10, better space utilization and better error correction. Should be able to easily set that up in the Proxmox web UI.

    Everything else sounds good. Don’t worry too much about it, you will find things you wish you did differently regardless, that’s part of the learning experience.


  • If you don’t want to be monogamous, don’t, just be polyamorous and date other polyamorous people. It’s a really bad excuse for cheating when there’s plenty of relationship arrangements where this isn’t a problem. There’s no need to deceive unwilling people and cheat on them when you can find partners who think the same as you and you don’t need to cheat on in the first place. You’re still dealing with other people with feelings on the end.

    I’d have to really go out of my way to cheat on my wife when the only rule is to have safe sex (or be safe in general).


  • 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.



  • You can’t really easily locate where the last version of the file is located on an append-only media without writing the index in a footer somewhere, and even then if you’re trying to pull an older version you’d still need to traverse the whole media.

    That said, you use ZFS, so you can literally just zfs send it. ZFS will already know everything that needs to be known, so it’ll be a perfect incremental. But you’d definitely need to restore the entire dataset to pull anything out of it, reapply every incremental one by one, and if just one is unreadable the whole pool is unrecoverable, but so would the tar incrementals. But it’ll be as perfect and efficient as possible, as ZFS knows the exact change set it needs to bundle up. It’s unidirectional, so that’s why you can just zfs send into a file and burn it to a CD.

    Since ZFS can easily tell you the difference between two snapshots, it also wouldn’t be too hard to make a Python script that writes the full new version of changed files and catalogs what file and what version is on which disc, for a more random access pattern.

    But really for Blurays I think I’d just do it the old fashioned way and classify it to fit on a disc and label it with what’s on it, and if I update it make a v2 of it on the next disc.


  • Both use Linux under the hood. You can even install LineageOS on some TVs.

    The only reason AndroidTV is bullshit is the manufacturers because casual users want shit like Netflix and Prime preinstalled. Google TV in particular comes with a lot of crap and the ads, which believe it or not some users take as a feature.

    But that’s not inherent to Android TV as an OS, it’s exactly like Android phones and manufacturers preloading a bunch of crap to make an extra buck. If your run AOSP you get none of that crap, and it’s fully open-source.






  • The language itself has gotten a bit better. It’s not amazing but it’s decent for a scripting language, and very fast compared to most scripting languages. TypeScript can also really help a lot there, it’s pretty good.

    It’s mostly the web APIs and the ecosystem that’s kinda meh, mostly due to its history.

    But what you dislike has nothing to do with JavaScript but just big corpo having way too many developers iterating way too fast and creating a bloated mess of a project with a million third-party dependencies from npm. I’m not even making this up, I’ve legit seen a 10MB unit test file make it into the production bundle in a real product I consulted on.

    You don’t have to use React or Svelte or any of the modern bloated stuff nor any of the common libraries. You can write plain HTML and CSS and a sprinkle of JavaScript and get really good results. It’s just seen as “bad practice” because it doesn’t “webscale”, but if you’re a single developer it’s perfectly adequate. And the reality is short of WebAssembly, you’re stuck with JS anyway, and WASM is its own can of worms.

    And even then, React isn’t that bad. There’s just one hell of a lot of very poorly written React apps, in big part because it will let you get away with it. It’s full of footguns loaded with blanks, but it’s really not aweful if you understand how it works under the hood and write good code. Some people are just lazy and import something and you literally load the same data in 5 different spots, twice if you have strict mode enabled. I’ve written apps that load instantly and respond instantly even on a low end phone, because I took the time to test it, identify the bottlenecks and optimize them all. JavaScript can be stupid fast if you design your app well. If you’re into the suckless philosophy, you can definitely make a suckless webapp.

    What you hate is true for most commercial software written in just about any language, be it C, C++, Java, C#. Bugs and faster response times don’t generate revenue, new features and special one-off event features generate much much more revenue, so minor bugs are never addressed for the most part. And of course all those features end up effectively being the 90% bloat you never use but still have to load as part of the app.


  • Is it directly exposed over the Internet? If you only port forward the VPN on your router, I wouldn’t worry about it unless you’re worried about someone else already on your LAN.

    And even then, it’s really more like an extra layer of security against accidentally running something exposed publicly that you didn’t intend to, or maybe you want some services to only be accessible via a particular private interface. You don’t need a firewall if you have nothing to filter in the first place.

    A machine without a firewall that doesn’t have any open port behave practically the same from a security standpoint: nothing’s gonna happen. The only difference is the port showing as closed vs filtered in nmap, and the server refusing to send any response not even a rejection, but that’s it.


  • It’s not impossible, been running my own email server for about 10 years and I inbox pretty much everywhere. I even emailed my work address and straight to inbox. I do have the full SPF, DKIM and DMARC stuff set up, for which I get notices from several email provides of failed spoof attempts.

    Takes a while and effort to gain that reputation, but it’s doable. And OVH’s IPs don’t exactly have a great reputation either. Once you’re delisted from most spam databases / old spam reputation is expired, it’s not that bad.

    Although I do agree it’s possibly one of the hardest services to self host. The software to run email servers is ancient and weird, and takes a lot to set up right. If you get it wrong you relay spam and start over, it’s rough.
