  • How do you cope with the amount of shit that goes on in the world?

    Jump

  • I read the news just to entertain myself. And then I ignore the content because most news are just depressing: Armed conflict here, murder there, capital offense, you get the gist.

    For several months I didn't read any news, that works too. You'll realize that most of the stuff in the tv and tabloids doesn't affect you.

    And for the third point I do whatever it takes to distract, lose in or occupy myself completely. That could be a book with a nice story or some outdoor activity. Yesterday I did some kind of mini-camping. I took my bicycle and brought a camping chair, gas stove, water and cocoa powder and rode a bit into the woods. And then I had some quiet relaxing time reading a book on my phone. The hot chocolate and a thick jacket kept me from freezing. It was only 10 °C/50 °F and a bit windy.I'll repeat that tomorrow but this time I'll switch the cocoa to tomato-soup-in-a-cup. The cocoa was too sweet for my taste.

  • According to Picard in the Movie First Contact money doesn't exist anymore. I guess those latinum bars are only used by Ferengies, in border systems and outside the Federation.

    That doesn't mean there's nothing that measures expense. The Federation might have a lot of available resources but they can't be infinite.

    1. Some episodes and movies show ships that are essentially flying holodecks. Energy doesn't seems to be a problem.
    2. That's the point: You don't need real-world things. The reason the holodeck is so large is to accommodate dozens of people at the same time.
    3. Some kind of multiplayer function across several holodecks should be possible.
    4. You either have a holodoctor for everyone who needs one or the few medical practitioners see a holo of their patient on which they operate. The holoroom the patient is in then replicates what the doctors are doing.

  • Proxmox setup - help needed

    Jump

  • Do I use BTRFS or ZFS? I tend to use ZFS because of its advantages when making backups. What would you do?

    Usually VMs are usually I/O starved therefore I would try to go as lightweight as possible and chose Ext4 or XFS (depending on what the VM is used for). The VMs can be backed up whole by Proxmox. You have more than enough space to do that and it's considerably easier to set up. And honestly how big could the containers and VMs be? I guess the containers are 50-200 MB and a VM a few GBs. That's almost nothing.

    Do I use QEMU/KVM virtual machines or LXC/LXD cointainers? Performance wise QEMU emulating the host architecture should be the way to go, right?

    LXC containers are way more lightweight than VMs. I depends on what you want to do. Docker and a file server work better in a VM so far but Pi-hole and Jellyfin run perfectly in a container.

    I shy away from running all services as Docker on the same machine for backup/restore purposes and rather have VMs per service. Is there anything wrong with this approach?

    I would go for LXC first. If that isn't possible or too cumbersome I would try docker (in a VM) next and one-VM-per-service last as they need the most resources.

    I’d love to keep NextcloudPi (because it’d make it easy to migrate settings and files) and there’s an LXD container for it. Would you recommend doing a switch to Nextcloud AIO instead?

    Sorry, no idea.

    I’ve equipped the Deskmeet X300 with a WiFi card and antennas. AFAIU trying to use WLAN instead of LAN will create some trouble. Has anyone running Proxmox on a machine with WLAN insteal of LAN access successfully?

    I would always try to connect it to LAN.

    I’m aware that Proxmox comes with a firewall, but I don’t feel very confortable using a software firewall running on the same machine that hosts the virtual machines. Is this just me being paranoid or would you recommend putting a hardware firewall between the internet access and the Proxmox server?

    No idea. I wouldn't mind a firewall container. If something breaks through you are fucked one way or the other. The firewall in your router isn't much different than any other.You should always go for Wireguard or another VPN to access your network from the outside.

    What else should I think of, but haven’t talked about/asked yet?

    Helper scripts for beginners: https://community-scripts.github.io/ProxmoxVE/Just give them a look.

    And it seems you are ignoring Proxmox' LXC. They are one of main reasons to pick that software.

    Edit: As an additional note: I ran about 6 or 7 VMs on a mini PC (Intel N100) with 16 GB RAM. RAM was almost used up and the cpu was at ~15 %.I then switched mostly to LXC and only one VM. The cpu was now at ~1% and RAM usage went down to 3 GB while still providing the same services as before.The power of containers, baby! :D

  • Why aren't all rooms holodecks?

    Jump

  • As for why all rooms aren’t holodecks/suites in the 24th century, probably due to power consumption.

    It's been a while and I might not remember correctly. Wasn't there an episode in Voy? with holographic lifeforms that rebelled against their creators and lived inside a flying holodeck ship? And there was that Insurrection movie in which a whole village was teleported into a giant holodeck ship.

    It seems possible.

  • They'll shut it down if you send more than a few megabytes down that tunnel. It's ok if you just need a connection (for ssh and stuff) but anything that generates a lot of traffic will be blocked.

  • IMO it depends on how much action is displayed in the movie. If there are a lot of dynamic scenes like car chases you'll need a high rate while 'simple' dialog scenes can get away with way less.

    That also means it depends on what movies you like to watch.

    Jump

  • I have a really hard time distinguishing between a good 4K webrip (15-20 Mbps) and remux (40-80 Mbps), so I have no issue keeping the majority of my library encoded at ~18Mbps

    That's because Netflix and the other common services usually only stream at 6-15 Mbps. You'll have to resort to Bravia Core or blu-ray discs to get anything in the 80 Mbps range.

  • What do people use for a shelf-stable backup

  • Is SSD really necessary? Everything I search up says SSDs have worse retention than HDD in cold storage. A couple TB of HDD is pretty cheap these days, and seems like a better cold storage option.

    SSDs are by design less susceptible and more robust. No moving parts and able to work in much harsher conditions than hdds will ever be able to. The standard set by JEDEC requires every consumer ssd to have a 1 year data retention while powered off at 30 °C (I think). That's the minimum it has to archieve but usually they are better than that. Do not buy the cheapest thumb drives because they contain the all the crap that wasn't good enough to make ssds from it.Btw you need to fire hdds up regularly too or the motor gets stuck. I think every 3-6 months was the recommendation.

    Yes, so now I’m thinking a rotation cycle. About every 5 years replace the drives with new ones, copy over all data.

    Don't make it flat every 5 years. Let a software monitor the SMART values of the drives and send notifications if the values indicate an increased change of a dying disc/ssd.

    Does this matter if I have a SATA->USB cable stored with it?

    Those are the first that fail, followed by the usb controller chip in the tray. Keep it as simple as possible. Removable trays are probably the best way but I'm not sure how much wear they can take.

    Do not buy 2.5" drives. This class will die out soon™. There were no new hdds introduced in years and ssds are often replaced by M.2 ones because of the faster connection.

  • Printing the photos won't help much. After 20 or so years they are all discolored. You can't prevent that.

    I think SSDs might be the best storage medium for you. Consumer-grade ssds have a 1 year data retention when powered off. That means at least once per year you have to turn it on and copy the data around one time to refresh the cells. This way it'll probably last several 100 years.

    You can't exactly make it fool-proof. Outside people will never know what you did to create your backup and what to do to access it. Who knows if the drives file system or file types are still readable after 20 years? Who knows if SATA and USB connectors are still around after that time?For example it is very likely that SATA will disappear within the next 10-15 years as hdds are becoming more and more an enterprise thing and consumers are switching to M.2 ssds.

  • Btrfs and zfs are self-healing.

    You can make a script to check for errors and autocorrection yourself but that needs at least a second hdd. On both drives are the same data and a file or database with the checksums of the data. The script then compares the actual checksums of the two copies and the db checksum. If they match -> perfect. If they don't match the file where there are two matching checksum is the good one and replaces the faulty one or corrects the db entry, whichever is defect. That's it. It doesn't have to be more complicated.

  • Any file systems Windows can read out-of-the-box are no good file systems. What Windows read? FAT and NTFS. Former is so basic it has no mechanisms to detect errors and bitrot and the later one is a mess.You should stick to ext4, btrfs and zfs.

    If you want to make if fool-proof then add a sticker with 'bring me to a computer shop to access my content'.

  • This will do nothing at all. Drives don't die by rust. They usually die because the motor somehow can't get the discs to spin. Very often dry lube is the reason. That can occur if you leave the drive off too long.

  • For local backups it depends on what you want to have:

    • The cheapest option is a usb or thumb drive. But you have to regularly plug it in and copy your backup on it.
    • The lazy option is to buy a NAS and configure a backup job that regularly creates a backup. Versioned, incremental, differentials and full backups are possible as is WORM to add a bit of extra security. You can configure a NAS to only turn on specified times, do a backup and then turn off again. This will increase protection against encrypting malware. WORM also helps in this case.Or just let it run 24/7, create backups every hour and install extra services on it like AI powered image analysis to identify people and objects and let it automatically tag your photos. Cool stuff! Check out QNAP and Synology or build a NAS yourself.A NAS can also be configured to present its content in a LAN by itself. Any computer will automatically connect to it if the access isn't secured by user/password or certificate.

    I recommend buying a NAS.

  • What about OpenMediaVault?Yes it focuses to be more of a NAS 'operating system' but the file sharing stuff is easy to set up. Any client can connect via nfs, smb or web to access any files.
