  • Frankly I'd prefer 4 slots at 4.0 speeds than 1 at 6.0.

  • Well actually it is very easy to spin up in docker and most of the configuration happens through env variables.

    juicefs itself only exists on the client side, so you basically only have to install and configure the CSI driver with helm.

    as it took me a few days to come up with this solution I'd be happy to share my config files.

    Performance wise is quite fast on sequential reads (it saturates my 2.5G bandwidth) and slower than I expected on sequential writes (for me it caps at 60MB/s). Postgresql seems happy. I saw no visible performance degradation with Authentic, Immich and Opencloud. Nextcloud installation took ages. I've yet to try it with jellyfish and the *arr suite.

    A simple NFS share would be faster, but it doesn't support replication, failover and CSI snapshots.

  • I have two storage nodes and one is much faster than the other.

    I'm currently evaluating a juicefs deployment based on two minio instances (one per node, replicated with async bucket replication) through a load balancer (sidekick) in failover. Because juicefs also needs a db for metadata, I went with valkey + sentinel.

    Juicefs provides a CSI driver that supports ReadWriteMany volumes and CSI snapshots and manages both read and write cache. Performance is much much better than Ceph. In theory it should be riskier (because of the async replication) but in practice I haven't yet lost a bit.

  • Because Ads are usually recognizable as such in your doom scrolling. Sometimes you can even filter them out with ad blockers.

    Ads in AI response is more similar to influencers not disclosing their sponsored messages.

  • Even if you are not connected to a WiFi network (so the toggle is off) background WiFi scans can still be used to track you by triangulating your position from nearby networks. This service is provided by Google for your convenience of course, so you don't even need to wait for GPS to pick up and they can track you without draining your battery too much.

    When I used to run a degoogled phone I was able to swap that service with an equivalent one provided by Mozilla, but they stopped supporting it after a while.

    We need someone like the EU to forbid bank apps to require Google's integrity checks so we can make modded Android great again.

  • You can find an older wired VR headset for cheap in the used market. Or even a Q2 if you are feeling fancier. Apart from lenses and resolution they are functionally identical to newer ones.

    My first game was Superhot VR and I instantly fell in love.

  • when they asked permissions?

  • Immutable distro debian based with GNOME

  • Probably the fact that they have many ISOs tailored for each supported hardware configuration, and they point the user to the right ISO with a clear wizard in their download page.

    Also basically it is an unbreakable gaming focused OS very close to SteamOS, that you don't have to maintain, and it comes preconfigured with Steam and the right drivers for your setup. I'm not the target audience, but I see the appeal.

  • You should be fine. Linux and BSD systems have te ability to load microcode updates at boot even if you don't update your BIOS.

    I'd be more concerned about the noise and power consumption.

    Also the number and the max speed of your NIC is a factor if you have a fast internet connection If you run OPNSense make sure your NIC is well supported (I had problems with realtek and paravirtualized cards). Otherwise you can always add more NICs with pcie cards.

  • I've just bought a few pack of these 8x8x500 sticks. And yes I tried some wood glue from the hardware store and they simply stuck very well to the PETG prints.

  • From the top:

    • 3 Chinese 2.5Gbit managed switches branded Horaco
    • 3 Chinese N100 "NAS" ITX boards (the cheaper green ones). They are in a Proxmox hyperconverged cluster (HCI)... aka Proxmox + Ceph.
      • Each one has a Pico PSU
      • a PCIE card (mounted on an right angle PCIE extender) with 2 additional 2.5Gb realtek NICs
      • 2 NVMe drives (mirrored boot drives)
      • a SATA SSD for Ceph
    • an empty shelf for a ITX board (an AM4 with a bunch of NVMe drives I have yet to move from my previous rack)
    • the last shelf can accomodate:
      • an automotive power distribution that feeds 12V to the switches and the N100 boards
      • a couple of 12V to USB PD boards, that I use to power the type c devices on the Rack shelves on the back
      • a (missing) TFX PSU that will power the AM4 board
      • a second TFX PSU that feeds 12V into the distribution blocks and powers basically anything else.

    I also have some rack shelves on the back:

    Needless to say I bought everything before the DRAM craze and I feel very sad for who has to work with the current market.

    Everything is mounted on custom 2U or 3U 3D printed 10" rack shelves.
