  • Zfs can become painfully slow if you don’t have RAM for it. I tried to run ZFS on my old setup with 64GB RAM and with moderate amount of virtual hosts and it was nearly useless with heavier io-loads. I didn’t try to tweak settings for it, so there might be some workarounds to make it work better, I just repartitioned all the storage drives with mdadm raid5 array and lvm-thin on top of that. Zfs will work with limited memory in a sense that you don’t risk losing data because of it, but as mentioned, performance might drop significantly. Now that I have a system which has memory to run raidz2 it’s pretty damn good, but with limited hardware I would not recommend it.

    LVM itself is pretty trivial to move on a another system, most modern kernels just autodetect volume groups and you can use them as any normal filesystem. If you move full, intact, mdadm array to a new system (and have necessary utils installed) it should be autodetected too, but specially with degraded array manual reassembly might be needed. I don’t know what kind of issues you’ve been getting, but in general moving both lvm and mdadm drives between systems is pretty painless. Instead of mdadm you could also run lvm-mirroring on the drives so it’ll drop one layer off from your setup and it potentially makes rebuilding the array a bit simpler on another system, but neither approach should prevent moving drives to another host.

    Lvm-thin is more flexible and while it might be a slightly slower on some scenarios I’d still recommend using that. Maybe the biggest benefit you’ll get from it is an option to take snapshots from VMs. Mounting plain directories will work too, but if your storage is only used by proxmox I don’t see any point in that over LVM setup.


  • Well, you’re not wrong, but that would still be a catastrophe modern world hasn’t yet seen. Those millions would become refugees and absolutely overwhelm European immigration system even with mass casualties due to riots, loss of water/food/medicine and who knows what else. Current oil prices would seem pretty cheap and global economy would take a massive hit causing homelesness, bankrupts, humongous loss of crops (due to fuel and fertilizer prices) and all kinds of havoc.

    Global west would suffer badly, China would become even stronger, Russia would benefit from that as well causing even more problems around Europe. Global trade with USA would practically collapse and pull USA down as well. In the global scale it doesn’t even matter that much if there’s a nuclear explosion somewhere too as results will be pretty nuclear anyways.


  • In Finland conscripts get 6.15 - 14.25€/day depending on how long they’ve been in service. Women get additional 1,50/day to cover underwear and hygiene products not provided by military. Also there’s options to get support from the state for example if you have family to feed while you’re serving.

    Hired personnel get roughly between 1600 and 8000€/month depending on rank, service age and a lot of other factors. Also they can get task-related extras.

    Comparing salaries is a bit irrelevant as our living expenses, taxes, health care, insurances and everything are wildly different. But for 100k you can get a pretty nice new car or a small apartment (not in Helsinki area). 200k will get you a decent house with garage, but again not in Helsinki.

    Also, we don’t really have infantry on a salary, as the conscription will take care of that. Practically all military personnel on salary are some sort of officers. More details are available on Finnish defence forces website.


  • For whatever reason ISPs tend (at least in here) to be pretty bad at keeping their DNS services up and running and that could cause issues you’re having. Easy test is to switch your laptop DNS servers to cloudflare (1.1.1.1, 1.0.0.1) or opendns (208.67.222.222, 208.67.220.220) and see if the problem goes away. Or even faster by doing single queries from terminal, like ‘dig a google.com @1.1.1.1’.

    If that helps you can change your router WAN DNS server to something than what operator offers you via DHCP. I personally use opendns servers, but cloudflare or google (8.8.8.8, 8.8.4.4) are common pretty decent choices too.


  • Depends on what you’re looking for, but for server use even a bit older hardware is just fine. My proxmox server has Xeon 2620v3 CPU and it’s plenty for my needs. For storage I went with SAS-controller, controllers are relatively cheap and if you happen to have a friend in some IT department you might get lucky when they replace hardware. RAM is a pain in the rear, but 8GB DDR4 rdimms work still just fine (if someone is interested I have few around)

    Personally I wouldn’t pay current prices for new hardware, specially if it’s for hosting. A bit older, but server rated, components give a lot more value for your money.


  • It seems like something so important that we’d have ironed it out, but the Constitution never explicitly laid out the terms, and it’s never been specifically answered by the Supreme Court.

    I guess lots of the world have similar situations with different laws. Generally, when those are written no one really asked what if president/minister/whoever is bat shit crazy demented old guy and should the law have guardrails for that.

    For the first thing, check out home assistant. They have at least some functionality already in place for local production and a ton of options ton consume the energy. Expanding that would pretty quickly spread out to wide audience. No idea how strict the devs are on pull requests/development, but that’s where I’d start if I was going to build something energy production/consumption related.


  • This, in turn, is different from APT, which is not Debian’s repository, but Debian’s package manager. So, technically, I could write “sudo apt install (anything)” to get any piece of software from Debian’s repository indeed, but I could also use that command to get software from somewhere else also in the form of a Deb package but which would not have come from Debian itself.

    With apt (and discover which uses apt/dpkg at the background) you can install anything from repositories configured on your system. So, if you want to use apt to install packages not built by Debian team you’ll need to add those repositories in your system, so they don’t just appear out of nothing.

    Some software vendors offers .deb packages you can install which then add their own repository on your system and then you can ‘apt install’ their product just like you would on native Debian software and the same upgrade process which keeps your system up to date will include that ‘3rd party’ software as well. Also some offer instructions on how to add their repository manually, but with a downloaded .deb it might be a bit easier to add repository without really paying attention to it.

    Spotify is one of the big vendors who have their own repository for Debian and Ubuntu and with Ubuntu there’s “ppa” repositories, which are basically just random individuals offering their packages for everyone to use and they are generally not going trough the same scrutiny than official repositories.








  • “installing apps from outside the Google Play Store”

    To me that implies it’s somehow different than just installing software. You could say ‘install from play store’ or ‘install from f-droid’ if you need to specify which app repository you should use, as that what it is. Sideloading might be an appropriate term if you need to upload apk to your device via USB-cable from your PC, which the term originally meant.

    to make it sound somehow dangerous or complicated in order to justify

    From the article:

    This “advanced flow” is for power users and enthusiasts who “want to take educated risks to install software from unverified developers.” Google says it was “designed carefully to prevent those in the midst of a scam attempt from being coerced by high pressure tactics to install malicious software.”

    Sure, the term itself comes from 1990s, but lately specially Google tries to twist that to mean something only ‘power users’ do and it comes with a ‘educated risk’.
