  • IME, beyond the install, it’s all distro- and desktop-specific.

    • How to find and install apps varies from distro to distro. IIRC, the Mint menu item is something obvious, like “Install software”, but on Arch (you’d have to hate your newbie to throw them into Arch), it requires a chicken/egg finding and installing a graphical installer. If you know the distro, this would be good information - or if you’re helping with the install, create a desktop launcher.
    • Showing them where settings are. Surprising to me, this has been super-not-obvious to my newbs. Even though the KDE Settings app is called “settings”, I think Windows and Mac folks are used to looking for settings in a specific place, rather than an app name - and in Windows, there’s can be several ways to get up different settings, like changing display stuff is always in a weird place. Again, maybe a desktop or panel shortcut would help.
    • One of my newbs used Mint for two years without opening a shell, so I don’t think that’s an issue. He even found and installed a piece of software he wanted, but I can’t remember if I originally showed him how to the first time. But that’s Mint. He did, however, need help setting up a printer, but that’s because he couldn’t find the settings program; he came from Windows originally.
    • Edge cases, like printers and other peripherals, can be hard, and I don’t think any amount of extra documentation is going to help, because almost every difficulty is practically unique. There’s a ton of online help for stuff like that already. And then, if they want to, eg, attach a game controller… well, that’s very specific and again varies by controller. I don’t think you can cover all of these edge cases.
    • Games can be hard only because of the indirection of having to install some other software, like Proton or Steam, creating an account, knowing how to check for compatability - there’s a lot of moving parts. It’s not just: go to the game’s web site, buy, download, and install something and run it, like I imagine it is on Windows. So maybe that would be useful - or - again - pre-installing one of the game stores and (surprise) making a shortcut would eliminate that.
    • Network connections. Again, I always find figuring out how to get to network configuration in Windows to be hard, and bizarrely having multiple ways of accomplishing the same task, so I’d guess going the other direction would be confusing. Having a note about how to get to the configuration would be handy.

    As I think about it, I realize that configuration under KDE of way more encapsulated and clear than on Windows, and people having learned the byzantine and myriad ways of Windows, KDE’s relative simplicity is confusing. Windows people look for configurations in places they’ve learned to look, which aren’t always where they are under KDE (I can’t speak much about Gnome - I don’t use it or set people up with it). MacOS isn’t as bad, having a similar configure-everything-through-a-single-settings-program approach.

    Anyway, that’s my experience.







  • My recommendation is to put all of the variables in an environment file, and use systemd’s EnvironmentFile (in [Service] to point to it.

    One of my backup service files (I back up to disks and cloud) looks like this:

    [Unit]
    Description=Backup to MyUsbDrive
    Requires=media-MyUsbDrive.mount
    After=media-MyUsbDrive.mount
    
    [Service]
    EnvironmentFile=/etc/backup/environment
    Type=simple
    ExecStart=/usr/bin/restic backup --tag=prefailure-2 --files-from ${FILES} --exclude-file ${EXCLUDES} --one-file-system
    
    [Install]
    WantedBy=multi-user.timer
    

    FILES is a file containing files and directories to be backed up, and is defined in the environment file; so is EXCLUDES, but you could simply point restic at the directory you want to back up instead.

    My environment file looks essentially like

    RESTIC_REPOSITORY=/mnt/MyUsbDrive/backup
    RESTIC_PASSWORD=blahblahblah
    KEEP_DAILY=7
    KEEP_MONTHLY=3
    KEEP_YEARLY=2
    EXCLUDES=/etc/backup/excludes
    FILES=/etc/backup/files
    

    If you’re having trouble, start by looking at how you’re passing in the password, and whether it’s quoted properly. It’s been a couple of years since I had this issue, but at one point I know I had spaces in a passphrase and had quoted the variable, and the quotes were getting passed in verbatim.

    My VPS backups are more complex and get their passwords from a keystore, but for my desktop I keep it simple.









  • You just need to wait for the proof of work to complete

    I will never find the irony in this anything other than pathetic.

    The one legitimate grievance against Bitcoin and other POW cryptocurrencies - the wasteful burning of energy to do throw-away calculations simply to prove the work has been done… the environmental cost of distributed scale meaningless CPU cycle waste purely for the purpose of wasting CPU cycles, has been so eagerly grasped by people who are largely doing it to foil another energy wasteful infotech invention.

    It really is astonishing.



  • E2E usually suffers from the same thing HTTP does: the MITM might not be able to read what you’re saying, but they know who you’re saying it to, and they may know in what context. This is a lot of information that can be used in profiling.

    So you end up with systems like SimpleX, where everyone has a different UID for every contact, but that has its own problems, as anyone who’s used systems like that are aware. We haven’t really solved making that a good user experience for messaging; I don’t see it translating to broader social media any time soon.

    Nostr has some really good specs and tooling that neatly addresses these topics, including great cryptography support, signing, ad-hoc IDs, and an entirely voluntary simple naming lookup; it doesn’t exactly solve zooko’s triangle, but it provides a toolset sufficient to mix and match characteristics for whatever your threat model is. Sadly, Nostr is utterly dominated by the crypto crowd (and is associated with some controversial personalities), and even if you’re not cryptocurrency-hostile, it’s a really dull echo chamber with little other content that has prevented people who might otherwise build interesting platforms in it from doing so.

    Mastodon was around for ages before (the in practice centralized) Bluesky; why did it take Bluesky to open a mass exodus from X?

    This is a hard problem to solve. Throwing E2E at it doesn’t make it easier; it’s just tossing a buzzword in.
