  • Something like vim-table-mode work as an improvement? You got me there though, tables can be a real pain in a terminal.

    For the second, I setup an on save hook or watch script to build a PDF and open it. Its been a minute, but I think I had to find a PDF viewer that would refresh if already open and keep the current position on subsequent opens.

    Best of luck finding something that works for you!

    Most startups I’ve applied to are Linux friendly.

    I currently work for a fortune 100 and managed to get a Linux machine purchased as a “lab” machine.

    I’m fully in control. IT doesn’t even know it exists. I’m not allowed on the corporate network, but I managed to get some internal corporate access through another department’s lab network (IT sanctioned) that has a VPN with a few routes to things like ticketing, time cards, and our internal wiki. Most of the stuff I need to do my job is in AWS and we are allowed to add home IPs to the security groups.

    IT still gives me a MacBook. I use it like once every 6 months.

    nixos-unstable is the only thing I will use currently.

    I’m running bleeding edge stuff like the latest kernel, Hyprland nightly, my own “shell” built from Gnome components and lots of custom stuff using GJS (Gnome JavaScript).

    If you get one, and you are free to do whatever on it, encrypt your drives like your job depends on it. I have a memorized passphrase, pin protected hardware key, and a key in TPM. No biometrics.

    As far as other nice things to have:

    • VPN: https://www.infradead.org/openconnect/ supports some common enterprise VPNs.
    • Communication tools (Teams, WebEx, Zoom, Slack, etc.). I tend to have access to 90% of what I need. My team is thankfully accommodating for the couple features I have issues with. Make sure you test things like Screen Sharing especially in Wayland if you use it.
    • VM: If you can get a corporate licensed image to run a corporate licensed version of Office, I recommend it. Office365 for web is missing a few features and often renders differently from native.
    • Password Manager and encrypt everything. System is encrypted as previously stated. My home volume (BTRFS) is encrypted with a different key/passphrase. My work’s sensitive files are encrypted yet again using rclone with different keys. I try to minimize attack surfaces by unlocking only what I need when I need it.
    • Backups. I use rclone to backup to our corporate OneDrive. Nixos is immutable and I have it setup with impermanence where every reboot is like a fresh install if I didn’t codify it my nixos-config which is tracked in git. I persist a few cache and setting directories in my home directory, but not much. I can restore my setup in like 20 minutes if I ever lost my machine.
    • Virtual mic and camera for noise suppression and blurring for communication tools that don’t have it built in.
    • Evolution EWS works okay as an Exchange email client. I had to hunt some weird settings like tenant ID to get it to work. I’ve been using Webmail or Outlook in a VM more often though as of late.

    I work in software dev as FYI. For the few issues I have, my team has more issues getting stuff working consistently on macOS for our project. I used that as a justification when requesting the laptop: my dev environment should closely match our runtime environment. Most of that is moot now since we use Nix flakes in our repos for local dev envs.



  • 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 use rclone and the Round Sync Android client.

    Supports a ton of back ends, self hosted, and commercial options. You can transparently encrypt with private keys you control.

    I personally use B2 Backblaze for storage.

    My phone backs up every night and Round Sync pushes them to B2. On my desktop I can mount as a volume. I can also access my storage from my phone going the other direction.

    I’ve done the same using SFTP if I don’t want the overhead of persistent file storage.

    It does not support indexing or previews for searching or finding say a photo. You can put whatever you want for data. So I have caches, indexes, and thumbnails that work in Linux. I can’t really make use of those on my phone though.

    Rclones bisync feature is also a bit dangerous when I tried to use it a year ago. I more than once “deleted” everything. B2 doesn’t delete by default, just hides, so I was able to recover. I now do unidirectional syncs from my machines to different buckets until I’m motivated to investigate a proper 3-way merge solution.




  • 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 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.



  • Some of this is a bit soft. Like, the 50% / 0% employment split says something about business’s ability to command labor. If we had an amazing economy with 50% unemployment, this would imply a large population that businesses either didn’t want or couldn’t access. And the former says something very different than the latter.

    The worry for me is the “didn’t want” part. Automation is increasing throughput. The ultra wealthy are netting most of the value instead of humanity as a whole. Workers are getting laid off to keep profits increasing. Greed blocks mass access to surplus while the available job pool shrinks. Culture warfare is used as a distraction to vilify those who aren’t staying afloat as immoral leaches.

    I doubt we could get to 50% without something like UBI. The unemployed would either die off due to lack of resources or a revolution happens to extract the horded wealth by force for another cycle of history. Doesn’t mean employers won’t try to min/max how much they can take.
