Nice, my HM90s have a really great cooling solution for the CPU (big silent fan, fine finned heat sink). But no cooling on the bottom side of the main board, which houses the RAM, a NVMe and two 2,5" SATA SSDs.

As usual, the arch wiki is super helpful also for non-arch distros https://wiki.archlinux.org/title/Lm_sensors#Adding_DIMM_temperature_sensors

Regarding mini PCs; Beware of RAM overheating!

I bought some Minisforum HM90 for Proxmox selfhosting, installed 64gb RAM (2x32gb DDR4 3200MHz sticks), ran memtest first to ensure the RAM was good, and all 3 mini PCs failed to various degrees.

The "best" would run for a couple of days and tens of passes before throwing multiple errors (tens of errors) then run for another few days without errors.

Turns out the RAM overheated. 85-95 C surface temperature. (There's almost no space or openings for air circulation on that side of the PC). Taking the lid off the PC, let 2/3 computers run memtest for a week with no errors, but one still gave the occasional error bursts. RAM surface temperature with the lid off was still 80-85 C.

Adding a small fan creating a small draft dropped the temperature to 55-60 C. I then left the computer running memtest for a few weeks while I was away, then another few weeks while busy with other stuff. It has now been 6 weeks of continuous memtest, so I'm fairly confident in the integrity of the RAM, as long as they're cold.

Turns out also some, but not all, RAM sticks have onboard temperature sensors. lm-sensors can read the RAM temperature, if the sticks have the sensor. So I'm making a Arduino solution to monitor the temperature with a IR sensor and also control an extra fan.

Lol, my tired brain thought for a moment EU was highlighting what it's doing for it's Lemmy-members 🤣

Game changing! I've never heard of Hoarder before, but will look in to it now.

LinkDing also has a REST API but I don't see the option to send attachment files

+1 for SingleFile

I recently tried LinkWarden, Linkding and Archivebox for making offline copies. They all had the same issue of running in to a Captcha or login wall for the sites I wanted to capture.
SingleFile to the rescue, as it uses your current browser session as a logged in and verified human.

Linkeding allows you to upload the singlefile html file attached to it link, but I didn't see such an option for Linkwarden.

How does this work? Where is additional space used for cache, server or client?

Or are you saying everything is on one host at the moment, and you use NFS from the host to the docker container (on the same host)?

This has been my thinking too.

Though after reading mbirth's comment I realised it's possible to use named volumes and explicitly tell it where on disk to store the volume:

    volumes:
      - my-named-volume:/data/
volumes:
  my-named-volume:
    driver: local
    driver_opts:
      type: none
      device: "./folder-next-to-compose-yml"
      # device: "/path/to/well/known/folder"
      o: bind

It's a bit verbose, but at least I know which folder and partition holds the data, while keeping the benefits of named volumes.

Yeah that's fair, permission issues can be a pain to deal with. Guess I've been lucky I haven't had any significant issues with permissions and docker-containers specifically yet.

[–] klangcola@reddthat.com 1 points 6 months ago

That makes sense. I've only ever used local storage on the docker-VM, but for sure it can make sense for using external storage

KDE Connect also works on Gnome, Windows and Android. I can't recommend it enough. Transfering a single image from phone to PC is instantaneous

Virtually all Norwegian oil and gas is exported.

95% of electricity in Norway is hydropower. During the last 10 years gridlines have been connected to central Europe, leading to hydropower being exported, and a subsequent 10x price hike for electricity in southern Norway.

Senterpartiet used to be called the "farmers party" , their policies are about supporting life in the districts, nature, environment and agriculture. And they are fiercely Eurosceptics

The Labour party tends to be more in favour of industry, as well as aligning with EU

As a Norwegian, yes this
