    2. Opia: The ambiguous intensity of looking someone in the eye, which can feel simultaneously invasive and vulnerable.
    3. Monachopsis: The subtle but persistent feeling of being out of place.

  • Is it practically impossible for a newcomer selfhost without using centralised services, and get DDOSed or hacked?
  • You don't have to be successful to get hit by bots scanning for known vulnerabilities in common software (e.g. Wordpress), but OP won't have to worry about that if they keep everything up to date. However, this is also necessary when renting a VPN from said centralised services.

  • Is it practically impossible for a newcomer selfhost without using centralised services, and get DDOSed or hacked?
  • You can simply set up a VPN for your home network (e.g. Tailscale, Netbird, Headscale, etc.) and you won't have to worry about attacks. Public services require a little more work, you will need to rely on a service from a company, either a tunnel (e.g. Tailscale funnel) or a VPS.

  • Cloudflare is bad. Youre right.
  • Ip address doesn’t expose where you live.

    https://letmegooglethat.com/?q=geoip+lookup

    Tunnels stop you from opening a port so nothing is exposed openly to the internet1 but it does not keep your ip private2.

    This is also incorrect.

    1. The entire purpose of CF tunnels is to expose sites on the internet
    2. CF tunnels (and services like it e.g. ngrok) rely on shared proxy servers that forward traffic based on HTTP host headers (which is why you can't forward arbitrary TCP traffic). The IP of the site will therefore have the shared IP of the company's proxy server instead of your own.
  • Cloudflare is bad. Youre right.
  • This is false. Some ISP's change IP's often, but some don't and sometimes geoip lookups can be really accurate. My IP has remained the same since I moved in, and a geoip lookup results in a coordinate less than a kilometer away. It does matter.

    Using disc spanning for RAID array

    I'm planning on building a new home server and was thinking about the possibility to use disc spanning to create matching disk sizes for a RAID array. I have 2x2TB drives and 4x4TB drives.

    Comparison with RAID 5

    4 x 4 TB drives

    • 1 RAID array
    • 12 TB total !

    4 x 4 TB drives & 2 x 2 TB drives

    • 2 RAID arrays
    • 14 TB total ! !

    5 x 4* TB drives

    • Several 4TB disks and 2 smaller disks spanned to produce a 4 TB block device
    • 16 TB total !

    I'm not actually planning on actually doing this because this setup will probably have all kinds of problems, however I do wonder, what would those problems be?

    ASRock N100m vs BKHD 1264 motherboard for NAS

    I'm trying to build a DIY NAS, I already have some (6) 3.5" SATA disks, a Mini-ITX case, and power supply, but I'm still unsure on which motherboard & CPU to get. I think a motherboard + N100 combo is a good option because of the price and power consumption.

    I'm currently using a MiniPC with an i5-6500T (4784 passmark) and an external HDD enclosure connected with USB using RAID-1 (software) which uses about 35W. The USB enclosure is limited to 2 slots, and I've heard from here that it can be problematic in combination with RAID. The N100 (5551) boards have a slightly better passmark score but most importantly more expandability (SATA & PCIe) and supposedly a lower power consumption. The i5-6500T has a TDP of 65W, the N100 a TDP of 6W, that doesn't say much but it seems to a lot better when looking at info online. The N100 also apparently has Quicksync support while the i5's support is limited and struggles to encode 1080p (100% CPU usage).

    There are 2 main boards I'm considering. The BKHD 1264 and the ASRock N100M. ASRock is a better known brand, but their version only supports DDR4 and 2 SATA ports while the BKHD board supports DDR5, has 6 SATA ports, and has 4 × 2.5G network ports. I've also heard complaints about high temps (90c) with the N100m because it only has passive cooling, while the BKHD board has active cooling and a large heat sink. However, the BKHD board is a bit more expensive (~€150 vs ~€130), but it seems worth it because I won't have to add an external HBA.

    What do you think would be the better option?

    EDIT 2024-05-26: I ended up getting the ASUS Prime N100I-D D4 because it's significantly cheaper (€95). It does have less SATA ports (1), but I accidentally bought a SATA card so that actually works out pretty well.

    non-Euclidean filesystem

    I noticed that I only had 5 GiB of free space left today. After quickly deleting some cached files, I tried to figure out what was causing this, but a lot was missing. Every tool gives a different amount of remaining storage space. System Monitor says I'm using 892.2 GiB/2.8 TiB (I don't even have 2.8 TiB of storage though???). Filelight shows 32.4 GiB in total when scanning root, but 594.9 GiB when scanning my home folder.

    !

    Meanwhile, ncdu (another tool to view disk usage) shows 2.1 TiB with an apparent size of 130 TiB of disk space! 1.3 TiB [#############################################] /.snapshots 578.8 GiB [#################### ] /home 204.0 GiB [####### ] /var 42.5 GiB [# ] /usr 14.1 GiB [ ] /nix 1.3 GiB [ ] /opt . 434.6 MiB [ ] /tmp 350.4 MiB [ ] /boot 80.8 MiB [ ] /root 23.3 MiB [ ] /etc . 5.5 MiB [ ] /run 88.0 KiB [ ] /dev @ 4.0 KiB [ ] lib64 @ 4.0 KiB [ ] sbin @ 4.0 KiB [ ] lib @ 4.0 KiB [ ] bin . 0.0 B [ ] /proc 0.0 B [ ] /sys 0.0 B [ ] /srv 0.0 B [ ] /mnt

    I assume the /.snapshots folder isn't really that big, and it's just counting it wrong. However, I'm wondering whether this could cause issues with other programs thinking they don't have enough storage space. Steam also seems to follow the inflated amount and refuses to install any games.

    I haven't encountered this issue before, I still had about 100 GiB of free space last time I booted my system. Does anyone know what could cause this issue and how to resolve it?

    EDIT 2024-04-06:

    snapper ls only shows 12 snapshots, 10 of them taken in the past 2 days before and after zypper transactions. There aren't any older snapshots, so I assume they get cleaned up automatically. It seems like snapshots aren't the culprit.

    I also ran btrfs balance start --full-balance --bg / and that netted me an additional 30 GiB's of free space, and it's only at 25% yet.

    EDIT 2024-04-07: It seems like Docker is the problem. !

    I ran the docker system prune command and it reclaimed 167 GB! !

    The Authy Flatpak worked by running the Snap inside

    snapcraft API called when updating flatpak

    I just tried to update all my flatpaks on my system using sudo flatpak update and got the following error: Error: While downloading https://api.snapcraft.io/api/v1/snaps/download/H8ZpNgIoPyvmkgxOWw5MSzsXK1wRZiHn_23.snap: Server returned status 404 It seems very strange to me. snapd isn't installed, so nothing should be making calls to the snap API as far as I'm aware.

    The download attempt seems to be coming from the com.authy.Authy app. sudo flatpak update com.authy.Authy makes the error appear. This is not the case for the other flatpak apps.

    It also shows the following EOL warning: ```

    Info: app com.authy.Authy branch stable is end-of-life, with reason: The Authy Desktop app have their End-of-Life. It is recommended to switch to use their mobile apps instead or other equivalent desktop apps. ```

    I suspect the app attempts to somehow install the snap package as a replacement (although that's a bit strange considering that one is also deprecated).

    Does anyone have an idea what might be going on?

    Here are the syscalls from during the update process mentioning snap. statx(AT_FDCWD, "/root/.local/share/flatpak/extra-data/26e56aeca2aa53c5983fbbcb115f72456cd28093171323b3144e280dac91135a/authy.snap", AT_STATX_SYNC_AS_STAT|AT_SYMLINK_NOFOLLOW|AT_NO_AUTOMOUNT, STATX_ALL, 0x7ffc09fb0920) = -1 ENOENT (No such file or directory) write(2, "Error: While downloading https:/"..., 141Error: While downloading https://api.snapcraft.io/api/v1/snaps/download/H8ZpNgIoPyvmkgxOWw5MSzsXK1wRZiHn_23.snap: Server returned status 404
