At the beginning of February I used a Sunday afternoon to make some space on my MacBook's internal drive to install #Asahi Linux as a daily driver. Apart from some minor annoyances it's working quite well.

Looking at the left side, I would have never guessed that those stones would be nearly white :O

Today I woke up to my LiveView app on fly.io being completely broken as any WebSocket connections were unable to get established. No deployment, no code change. Since it’s an colder codebase, longpoll fallback was not enabled. Works now with long polling, but websockets still don’t 🤷🏻♂️

A simple ZFS mirror is a RAID1. ZFS just has different terms it uses for many things. So you tell ZFS to replace the disk and it will rebuild (resilver in ZFS terms) the RAID (pool).

ZFS does both:
zpool create mypool mirror /dev/disk1 /dev/disk2
And then you can create separate datasets (like folders, but they can have different options like compression, automatic snapshots, etc.)
zfs create mypool/dataset1
zfs create mypool/dataset2
zpool create mypool mirror /dev/disk1 /dev/disk2

Nice! If you have a way to measure average power consumption, I’d be interested to know.
Note that with ZFS, you’ll still want a mirror aka RAID1.
I’m hearing lots of good things about Proxmox, but I never tried it. All my servers run plain Ubuntu right now :)

I‘d want to add two hard drives in a RAID for sure in that case, but that would then be another 10 watts.
So all I’m saying is don’t underestimate the impact of inefficient hardware :D

The Mac Mini I have runs at 5 watts idle power (up to ~40 watts when converting videos with immich), but averaged over the year that’s pretty much negligible (10W over ten years at 0.25€/kWh is 219€). And it could do all the things I currently have at Hetzner.

So even if a hard drive or memory module fails early, that’s plenty of headroom just from saved energy costs. My hetzner dedicated server runs on a consumer i7-8700. For all you’ve described you want to run, a recent i5 or AMD equivalent would cover it pretty much guaranteed.

Concerning the hardware: I’m probably lucky, but I never had a problem with consumer hardware, nor server hardware so far. So assuming that even consumer hardware achieves 10 years of runtime, a difference of 100W average accumulates to 8760 kWh (2190€ at 0.25€/kWh).

I mean sure, money might not be the problem here. For me it’s mostly just the absurdity of such a figure. 6.5kWh a day is nearly 2400kWh as year. Last year my whole flat (2 people) used 2500 kWh overall. So for me a server that needs more than 50W on average is just not reasonable for what it does.

Also, many people suggest to not use hardware RAID cards nowadays. I’d always choose a ZFS over a hardware RAID, but maybe that specific card in the server has a passthrough mode.

Personally, I‘d choose the Minisforum one. Here‘s someone reporting 6,5kWh a day with a T440 (forum.level1techs.com/t/power-effi...). Pretty sure your one here would be less, since fewer RAM modules and no GPU, but as mentioned servers are unnecessarily power hungry. Especially dual CPU ones.

I was thinking since Goatmire Elixir turned out pretty good I should maybe do another one. 30th of Sep - 2nd of Oct this year.
We have a list to notify you about the progress and when tickets drop, getting on that list also helps indicate interest.

Yep. I‘m pretty sure most stuff would stop working here. Germany has a national debit system called Girokarte, so some card payments might still work, but that’s out of my control. Many banks also fully rely on Visa or Mastercard 🤷🏻♂️

To access the stuff externally I use Tailscale (which is a US company…) but I also have a manually set up WireGuard VPN. I just stopped actively using that since Tailscale is more convenient. If I need it it’s still there though :)

I could have also used the iOS app, since it needs to download all iCloud Photos temporarily anyway to hash them for checking if they are already synced. To do that I needed to let my phone run the app with dimmed screen over night a couple of times… But now it syncs flawlessly.

For the initial photo sync to Immich (40000 photos + a couple thousand videos; 1TB) I used the Mac Mini and made it download the library locally. Then used github.com/RhetTbull/os... and Immich‘s CLI to sync the photos to Immich.
