  • Standalone cameras

    Jump

  • I'm running Dahua cameras. They can pull new firmware straight over the internet, but they don't rely on any cloud services. All kinds of flavours available and they do run on POE.

  • LG TV shown scanning LAN for third-party phones and other devices

    Jump

  • https://thecybersecguru.com/news/lg-smart-tv-spying-investigation/

    There are roughly 216 million LG smart TVs in homes, hospitals, offices, and hotels worldwide. Each one maps its local network, fingerprints its content, and logs audio, on or off, whether you’re talking to it or to someone else, whether you’re online or not, and feeds that into an ad engine that sells access to your living room.

    They do a lot more than just scan the network.

  • Your LG TV Might Be Spying on Your Entire Network While You Think It's Turned Off

    Jump

  • Mine is several years old by now, I doubt that the firmware on that has all the options enabled. And also I live in a pretty rural area, there's no open networks around.

    But something LG has achieved with this, I'm going to look for other brands when I'm on a market for new TV. Which I hope will be many years in the future, maybe there's a change on products while waiting and something better is available by then.

  • Your LG TV Might Be Spying on Your Entire Network While You Think It's Turned Off

    Jump

  • My LG TV is blocked from my network and always has been. However, the andriod tv connected to it is a different thing, so it's more or less lost cause anyways and I haven't had enough incentive to block the android box from the rest of network since it'd need some tweaking so that casting and other occasionally used features still work. And even if I'd block the android tv box there's still our cellphones gathering all the data, so I'm pretty much just running things on hopium that EU offers at least some protection on my data.

  • Very interesting piece of history. Thank you!

  • Google Maps renames “Lake Ontario” to “Lake America” even faster than US government

  • You are obviously correct on that but we could also grab pitchforks about the term 'sideloading'. Everyone knows what 'installing' is and 'sideloading' (in this context) is just a bullshit term to make it feel like something mysterious and/or dangerous. Installing software from play store is no different than installing from f-droid.

  • What is your cloud backup solution?

    Jump

  • Another recommendation for storagebox from here. Cheapest option I've found and they are pretty reliable. I use proxmox backup server to sync my VMs there (encrypted of course).

  • Why homelab?

    Jump

  • There's plenty more reasons than filesystem corruption to use clean shutdown and even just plain UPS without any status information to the host. I haven't seen a full drive corruption due to power loss ever. Various levels of corruption, yes, but not 'all the data is gone' scenario due to filesystem being broken. But I have seen multiple hard drives which have died on host shutdown without any warning (no smart errors or such), after power loss they just refused to start again.

    Just today we had multiple short (~30 second) power outages and without UPS that would've put considerable strain on my hardware. Gladly those are pretty rare and those were well short enough that my UPS kept the system running, without one that would've meant that my hypervisor would've crashed and that would've resulted on several unclean reboots for the VMs.

    Also, back to filesystems, with selfhosting, some kind of hypervisor is often in the picture, so the drive activity is generally much higher than with single workstation and corruption on a single file or some part of filesystem is way more likely. Total data loss is pretty unlikely, but a corrupted VM image can be a pretty big deal, regardless if it's filesystem or single file which is the main issue.

    there’s no standardized mechanism for forcing applications to save

    On Linux (and I guess BSD and other *nix variants) there is. SIGTERM is exactly for that situation. Sure, programs can choose to ignore it, but I don't think I've ever seen at least any FOSS software which wouldn't respect that. Of course the program might crash and cause loss of data, but the mechanism is there.

    You're of course generally correct about modern filesystems being more resilient to power loss, but they're not immune to problems and also you've omitted a large chunk of other reasons why people like to have UPS on their system, with or without monitoring them.

    For me personally the hardware is least interesting part of running a homelab. I'd happily run everything on VPS if there was no constraints on money or bandwidth (among other things). But as the limitations are there running things on my hardware is a necessary evil and for that an UPS or two are practically must to have to prolong life span of hardware and prevent data losses. Of course that's just one box to check on the stack, but when planning for a home server setup for anything I'd say it's a pretty vital part for the whole setup.

  • Why homelab?

    Jump

  • But in the real world it doesn't really matter if it's the whole filesystem or an idividual file which is corrupted. Either way the data is compromised and nitpicking that the filesystem is actually just fine doesn't make any difference.

  • Why homelab?

    Jump

  • Modern filesystems can corrupt as well with unclean shutdown. They are just less likely to do so. My server stores photos of our life over couple of decades with other nearly irreplaceable data so having the UPS and clean shutdown on power loss gives at least some confidence that the files stay where they are.

    Of course I also run backups of the data, but it's another layer on data safety setup.

  • Data centers’ ‘oh s--t’ moment

    Jump

  • Heat exchangers and/or heat pumps to move energy to water and then pump that to district heating network which then takes care of heating of all kinds of buildings.

  • Data centers’ ‘oh s--t’ moment

    Jump

  • Just to add to your points, all of those are already a thing in colder climates. Google DC in Finland is one example. When it's heavily below zero half of the year it's just not possible to run open loop systems and there's plenty of use for the excess heat. Some DCs just donate the waste heat to municipal heating. PR obviously plays role in that, but that's easy way to get rid of the heat and datacenters don't need to manage the heating network and fluctuations on demand, so they also benefit from someone who'll just take the heat away from their 'hands'. Also sound is automatically better managed since you need decent insulation on the buildings to avoid condensation and other problems which come when temperature differences are pretty huge between inside and outside of the building.

  • Anti-AI fonts are useless and harmful

    Jump

  • My brain reads those as 'thee', or however that old English should be written (thee, thou, thy..), so the image is that someone pretty pompous Englishman from 1700s with a powdered wig found fediverse.

    Plus I tested those on duck.ai just for fun and it has absolutely no trouble of reading the thorns, so it only makes reading harder for other humans, specially for us whose native language isn't English.

  • Aaron Swartz was prosecuted for scraping, while Meta does it without consequence

    Jump

  • didn’t he break into a network closet and patch directly into their servers?

    No. He placed a computer in a unlocked network closet and used that to download a bunch of data from JSTOR (which he had acces to, and a lot of the data is public domain anyways) and kinda-sorta caused DDoS attack against the service. Prosecution then slapped him with a shitload of federal charges which (in my opinion) were largely at least massively exaggerated if not straight made up. Threat of 50 year jail sentence and million(s) in fines then pushed him to take his own life.

    Wikipedia has pretty detailed info about him and the whole case.

  • Is this a good first homeserver?

    Jump

  • Immich itself is running on docker, so it's the same than every other setup. For me it just makes more sense to run that on a separate VM than keeping all the docker containers in a same operating system due to backups, manageability, access control and so on, even if it costs a bit of memory to run a full operating system. Biggest consumers on the host process list are immich-api, postgres-processes and immich. Actual used memory is around 2,5GB for the whole system with ~5GB on buffers/cache.

    But I often import hundreds of raw photos at a time from DSLR and/or 4K video footage from my drone and processing those takes quite a lot of memory. With less memory and slower drives the whole thing crashed when importing bigger batches to out of memory erros, but I suppose it could run just fine with even less than 4GB of memory, if the usage pattern is just to upload photos from your cellphone in a relatively slow pace.

  • Is this a good first homeserver?

    Jump

  • It's a full VM, so OS and docker creates some overhead, but before I upgraded the server it ran on far less resources and specially big imports were painfully slow. Also that's just the number from proxmox console, so there's likely some cache included, but stats show that the VM pulls over 10G every now and then with shorter spikes over 20GB of consumed RAM.

    As I mentioned, it can run on way less, but it feels a lot more responsive when it has enough resources.

  • 16GB of ram is a bit low for the load you're planning. That can work, but Nextcloud and Immich are pretty hungry for memory. My immich instance right now is using 7GB of RAM and nextcloud uses a bit over 4. I have the hardware to give them pretty much all the memory they want, so those are not absolute minimum amounts, but I wouldn't try to run either with less than 6GB allocated memory on my load (few users, about a terabyte of data on both).

    With 16GB you can pretty much forget using ZFS, but that's not a big loss. LVM works just fine and with thin provisioning you can use snapshots too just fine. Bigger SSD/NVME for drive cache would be good. And of course all-SSD setup would be nice, but that gets expensive pretty fast. Second ethernet port might be nice to have, depends on how you're planning to build your setup. Otherwise that hardware looks pretty good, altough I'd search for something second hand. CPU is most likely a bit overkill for what you need, I have Xeon E5-2620 v3 @ 2.40GHz and it's running on around 10% load most of the time.

  • You're of course correct on that, but Mullvad the company gave (somewhat) clear news release that their company is against far right (or left or any 'far' direction) politics. I'm not a customer and I couldn't care less about Mullvad, but I think it's worthwhile to keep in mind that company isn't the same than one of it's founders.

    Of course if that is a breaking point to you, feel free to vote with your wallet and I can very much understand the decision, but there's very few fully reputable companies around so I can also understand if that's not a hill to die on.

  • I've try to set up my E-Mail server 📬. Dovecot + Postfix. I can sends, but I can't receives.

    Jump

  • Don't send spam, behave nicely, have proper configuration on postfix and dovecot, set up SPF and preferably DKIM, keep your domains reputation clean and so on. You'll likely still end up on some lists, so you need to manually dig them trough and ask nicely for removal.

    Self hosting email has a pretty bad reputation and many will strongly advice against it, but in reality it's really not that bad. But email as a whole is more complex beast to manage than simple website or running Jellyfin for your family and friends. You need to understand how the mail routing side of things work (SMTP itself, authentication for it encryption included and so on) and also you need to understand how DNS works and how various entries are related to mail transport. Then you'll likely want at least some kind of spam filtering and so on. And with email you'll need to have proper backup scenario too so that you don't lose the likely pretty important data. All of that is perfectly doable and it's not as difficult as many claim it to be, but there's a bunch of stuff you need to understand and implement all of them correctly.

  • I've try to set up my E-Mail server 📬. Dovecot + Postfix. I can sends, but I can't receives.

    Jump

  • There's various permission errors on the log file, I'd start from those. Also your dovecot configs seem a bit funny to me, usually mails are not stored to user home directories with dovecot, but instead somewhere under /var, likely you'll want /var/vmail. Logfiles are pretty good with these tools, so pay close attention to those.

    And take your time to understand what the config options actually do. Too permissive configurations will get your sever to every spamlist on the world pretty quickly.
