  • OS: NixOS (high learning curve but its been worth it). Nix (the config language) is a functional programming language, so it can be difficult to grok. Documentation is shit as its evolved while maintaining backwards compatibility. If you use the new stuff (Nix Flakes) you have to figure what’s old and likely not applicable (channels or w/e).

    BYOD: Just using LVM. All volumes are mirrored across several drives of different sizes. Some HDD volumes have an SSD cache layer on top (e.g., monero node). Some are just on an SSD (e.g., main system). No drive failures yet so can’t speak to how complex restoring is. All managed through NixOS with https://github.com/nix-community/disko.

    I run stuff on a mix of OCI containers (podman or docker, default is podman which is what I use) and native NixOS containers which use systemd-nspawn.

    The OS itself I don’t back up outside of mirroring. I run an immutable OS (every reboot is like a fresh install). I can redeploy from git so no need to backup. I have some persistent BTRFS volumes mounted where logs, caches, and state go. Don’t backup, but I swap the volume every boot and keep the last 30 days of volumes or a min of at least 10 for debugging.

    I just use rclone for backups with some bash scripts. Devices back up to home lab which backs up to cloud (encrypted with my keys) all using rclone (RoundSync for phone).

    Runs Arrs, Jellyfin, Monero node, Tor entry node, wireguard VPN (to get into network from remote), I2C, Mullvad VPN (default), Proton VPN (torrents with port forwarding use this), DNS (forced over VPN using DoT), PiHole in front of that, three of my WiFi vlans route through either Mulvad, I2C, or Tor. I’ll use TailsOS for anything sensitive. WiFi is just to get to I2C or Onion sites where I’m not worried about my device possibly leaking identity.

    Its pretty low level. Everything is configured in NixOS. No GUIs. If its not configured in nix its wiped next reboot since the OS is immutable. All tracked in git including secrets using SOPS. Every device has its own master key setup on first install. I have a personal master key should I need to reinstall which is tracked outside of git in a password manager.

    Took a solid month to get the initial setup done while learning NixOS. I had a very specific setup of LVM > LUKS encryption /w Secure Boot and Hardware Key > BTRFS. Overkill on security but I geek out on that stuff. Been stable but still tinkering with it a year later.


  • I’ve been screaming its just wage theft. My city provides tax breaks for occupancy (employees prop up the local economy buying lunch). They are making me pay for gas, time, and car maintenance (and lunch but fuck them, I’ll just not eat) for this tax break which goes to C-level bonuses/shareholders. Its just another way of skimming off the top of employee wages.

    We worked fully remote for nearly 2 years and the hybrid policy just keeps getting worse and worse. Coupled with quarterly riffs, I also suspect this is to avoid severance pay/unemployment while accelerating the down sizing. Yet our CEO bonus keeps going up and up despite our stock plummeting since the end of COVID lock downs.








  • Immutable Nixos. My entire server deployment from partitioning to config is stored in git on all my machines.

    Every time I boot all runtime changes are “wiped”, which is really just BTRFS subvolume swapping.

    Persistence is possible, but I’m forced to deal with it otherwise it will get wiped on boot.

    I use LVM for mirrored volumes for local redundancy.

    My persisted volumes are backed up automatically to B2 Backblaze using rclone. I don’t backup everything. Stuff I can download again are skipped for example. I don’t have anything currently that requires putting a process in “maint mode” like a database getting corrupt if I backup while its being written to. When I did, I’d either script gracefully shutting down the process or use any export functionality if the process supported it.




  • I’m on Graphene. Mullvad is only 1% for me with 16h30min since last on a charge. I’m at 56% with 1h30m screen time.

    I used GPS as I did some driving with maps and my music app accounting for 29% of my battery usage.

    I throw my phone on the charger at night figuring battery tech and software management is good enough.

    Are you WiFi or mobile? I get shitty mobile service so if I’m off WiFi my battery tends to go to shit. The VPN usually accounts for more as I assume it keeps reconnecting.



  • Ok. So a device didn’t get a dhcp address? No problem… It creates it’s open IP address and starts talking and try to get out on internet on its own…

    Its not that different from a conceptual point of view. Your router is still the gate keeper.

    Home router to ISP will usually use DHCPv6 to get a prefix. Sizes vary by ISP but its usually like a /64. This is done with Prefix Delegation.

    Client to Home Router will use either SLACC, DHCPv6, or both.

    SLACC uses ICMPv6 where the client asks for the prefix (Router Solicitation) and the router advertises the prefix (Router Advertisement) and the client picks an address in it. There is some duplication protection for clients picking the same IP, but its nothing you have to configure. Conceptually its not that different from DHCP Request/Offer. The clients cannot just get to the internet on their own.

    SLACC doesn’t support sending stuff like DNS servers. So DHCPv6 may still be used to get that information, but not an assigned IP.

    Just DHCPv6 can also be used, but SLACC has the feature of being stateless. No leases or anything.

    The only other nuance worth calling out is interfaces will pick a link local address so it can talk to the devices its directly connected to over layer 3 instead of just layer 2. This is no different than configuring 169.254.1.10/31 on one side and 169.254.1.11/31 on the other. These are not routed, its just for two connected devices to send packets to each other. This with Neighbor Discovery fills the role of ARP.

    There is a whole bunch more to IPv6, but for a typical home network these analogies pretty much cover what you’d use.


  • I don’t know about Nvidia specifically, but I mostly only see RSUs offered to Staff/Principal level engineers or Director and above on the management track. Many times with a multi year vestment period to act as a retention tool. You can make out good at the exiting end of the deal.

    IMHO its a shitty practice. There is risk if the C-level pulls some stupid shit tanking the stock. The reward could just as easily be distributed to employees with a profit sharing bonus that eliminates the risk of my options tanking while vesting. Let the employees convert to options if they want to stake on future company performance.

    At least in the US, I could have used the value of my options earlier in life to help with student loans, buying a house, medical issues, having kids, etc. I grew up poor. I “pulled myself up from bootstraps” and am doing well now. I still think the whole system is a dumb gimmick.


  • I haven’t tested in Windows, but this is my setup Linux to Linux using rclone which the docs say works with Windows.

    Server

    • LUKS
    • LVM
    • Volgroup with a mishmash of drives in a mirror configuration
    • Cache volume with SSD
    • BTRFS /w Snapshots (or ZFS or any other snapshotting FS)
    • (optional) Rclone local “remote” with Crypt if you want runtime encryption at rest and the ability to decrypt files on the server. You can skip this and do client side only if you don’t want the decryption key on the server.
    • SFTP (or any other self-hosted protocol from https://rclone.org/docs/)

    Client

    • Rclone Config /w SFTP (or chosen protocol)
    • (optional) Rclone Config /w Crypt
    • Rclone mount with VFS.

    I use this setup for my local files and a similar setup to my Backblaze B2 off site backups.

    The VFS implementation has been pretty good. You can also manually sync. Their bisync I don’t fully trust though.

    I can access everything through android using https://github.com/newhinton/Round-Sync. Not great for photos though as thumbnails weren’t loading without pulling the whole file last I tested a year ago.


  • Follow the money. Israel is an R&D hub with large investments from American companies. We also don’t want their tech going to an unfriendly nation.

    I work in R&D and we occasionally acquire startups from Israel. We literally have someone employed in/from Israel scouting the startup scene for acquisitions and joint ventures.

    Biden is unsuccessfully trying to make everyone happy in a situation where that is impossible. Its very clear its profits over people when forced into choice.
