I think you can mount an ISO image under your running system and make changes. I found a couple of guides that might be helpful:

How to Mount an ISO File on Linux

Edit and repack .iso bootable image

I haven’t done this before, but I think you can chroot into the mount directory, and run package manager commands in the mounted image to install another package.

Or I have an alternative suggestion that might or might not be easier. I’ve been hearing a lot about immutable/atomic distros, and people designing their own images. You could make your own ublue image, for example, with whatever you want on it.

A promising looking starting point is github:ublue-os/startingpoint. Ignore the “Installation” instructions, and follow the “ISO” instructions instead.

Or I saw recently an announcement of a new way to build atomic images that is supposed to be easier than ever, BlueBuild

Oh is that where all the memes went? My instance isn’t federated with lemmy.world so it just looked like the star trek energy vanished.

While I’m here… I finally finished season 4 of Discovery. That show has been getting much stronger as it goes on IMO. I especially enjoyed the last ~3 episodes! I also like the take on the “villains” of the late season (the two humanoid ones). It’s a refreshing departure from unsympathetic, plain evil antagonists.

LEDs should last for tens of thousands of hours. There may have been a manufacturing defect in OP’s case.

It scrolls smoothly, it doesn’t snap line by line. Although once the scroll animation is complete the final positions of lines and columns do end up aligned to a grid.

Neovim (as opposed to Vim) is not limited to terminal rendering. It’s designed to be a UI-agnostic backend. It happens that the default frontend runs in a terminal.

I don’t know if it’s your cup of tea, but Neovide provides smooth scrolling at arbitrary refresh rates. (It’s a graphical frontend for Neovim, my IDE of choice.)

A credit system is an essential piece of a robust economy

(This is probably explained in the article, but I don’t have a subscription.) The National Ignition Facility (NIF) creates fusion by bombarding a fuel capsule with lasers. The laser beams are reflected many times to build up energy, and to converge on the capsule. There is energy loss during that process so the laser energy that goes into the capsule is a small fraction of the electricity used to fire the lasers. When they say they got twice the energy out, that’s compared to the laser energy going into the capsule, not the energy required to fire the lasers. So its a long way off from a practical power plant, but still important progress.

The purpose of the NIF is to study what goes on inside the capsule - for better understanding, and to figure out how to get the most possibly energy out of a fusion reaction. Once they have figured that out a possible next step is to design a system that delivers laser beams with less input energy. It’s easier to do that after you know the ideal way for beams to interact with the capsule. Or maybe we never build a power plant based on the NIF design, but the findings help to make other reactor designs work.

If I’m doing more than one cracking two together is best. For the last one, countertop.

I get the flat, inside-the-sink idea. But I’d want to clean either way, and I clean the counters more often than I clean the sides of the sink.

Well you’re really feeding my Nix confirmation bias here. I used to use Ansible with my dot files to configure my personal computers to make it easy to get set up on a new machine or server shell account. But it wasn’t great because I would have to remember to update my Ansible config whenever I installed stuff with my OS package manager (and usually I did not remember). Then along came Nix and Home Manager which combined package management and configuration management in exactly the way I wanted. Now my config stays in sync because editing it is how I install stuff.

Nix with either Home Manager or NixOps checks all of the benefits you listed, except arguably using a “known” programming language. What are you waiting for?

For the PaperWM fans, this is a dedicated WM based on the same idea

This is basically the plot of Loki

AFAIK the best thing you can do to improve your coffee-freezing process is to prevent moisture from getting into the beans when you thaw. If you let it, moisture from the air will condense on the cold beans. So keep the beans in a closed, airtight container until they come to room temperature. (Airtight because water vapor is air.) So yeah, jars are good for this. Or sealed freezer bags should work too.

I haven’t used Krita. But I can tell you that those wrappers are “options” defined by NixOS modules. There is documentation for writing them in the NixOS Manual.

Built-in NixOS options are documented in the Configuration Options Appendix with links to implementations which provide helpful examples when writing your own options.

Hmm, good point. But it was Ursula Le Guin who coined the word. Maybe there’s a workable reference in Left Hand of Darkness, or The Dispossessed.

Well ok, they both use symlinks but in different ways. I think what I was trying to say is that in NixOS it’s symlinks all the way down.

IIUC on Fedora Atomic you have an ostree image, and some directories in the image are actually symlinks to the mutable filesystem on /var. Files that are not symlinks to /var (and that are not inside those symlinked directories), are hard links to files in the ostree object store. (Basically like checked-out files in a git repository?)

On NixOS this is what happens if examine what’s in my path:

$ which curl
/run/current-system/sw/bin/curl

$ ls -l /run | grep current-system
/run/current-system -> /nix/store/p92xzjwwykjj1ak0q6lcq7pr9psjzf6w-nixos-system-yu-23.11.20231231.32f6357

$ ls -l /run/current-system/sw/bin/curl
/run/current-system/sw/bin/curl -> /nix/store/r304lglsa9i2jy5hpbdz48z3j3x2n4a6-curl-8.4.0-bin/bin/curl

If I select a previous configuration when I boot I would get a different symlink target for /run/current-system. And what makes updates atomic is the last step is to switch the /run/current-system symlink which switches over all installed packages at once.

I can temporarily load up the version of curl from NixOS Unstable in a shell and see a different result,

$ nix shell nixpkgs-unstable#curl  # this works because I added nixpkgs-unstable to my flake registry
$ which curl
/nix/store/0mjq6w6cx1k9907vxm0k5pk7pm1ifib3-curl-8.4.0-bin/bin/curl  # note the hash is different

I could have a different version curl installed in my user profile than the one installed system-wide. In that case I’d see this:

$ which curl
/home/jesse/.nix-profile/bin/curl

$ ls -la /home/jesse | grep .nix-profile
.nix-profile -> /nix/var/nix/profiles/per-user/jesse/profile

$ ls -l /nix/var/nix/profiles/per-user/jesse
profile -> profile-133-link
profile-130-link -> /nix/store/ylysfs90018zc9k0p0dg7x6wvzqcq68j-user-environment
profile-131-link -> /nix/store/9hjiznbaii7a8aa36i8zah4c0xcd8w6d-user-environment
profile-132-link -> /nix/store/h4kkw1m5q6zdhr6mlwr26n638vdbbm2c-user-environment
profile-133-link -> /nix/store/jgxhrhqiagvhd6g42d17h4jhfpgxsk3n-user-environment

Basically symlinks upon symlinks everywhere you look. (And environment variables.)

So I guess at the end everything is symlinks on NixOS, and everything is hard links plus a set of mount paths on Fedora Atomic.

If you put an FHS on the actual system you wouldn’t be able to install multiple versions of the same package, updates wouldn’t be atomic - you wouldn’t get the big selling points of Nix.

When science kills the mystery, semantics keeps the debate alive!

To answer your other question, yes there are still single-cell organisms evolving into new species all the time, in the ocean and elsewhere. That includes new multi-cellular species evolving from single cells all the time. But it takes a long time to develop from cell, to clump of slime, to something with legs. So you might not notice the changes if you aren’t super patient.

Or were those separate questions? Are you asking if chickens descended from single-cell organisms? Yes they did. With a lot of steps in between.

“Atomic” is a catchy descriptor! Atomic distros for the Atomic Age! It could be an umbrella term since NixOS and Guix are atomic, but instead of images and partitions they use symlinks, and patch binaries to use full paths for libraries and programs that they reference. So there are image-based distros, and I guess expression-derived distros which are both atomic.

I haven’t tried image-based distros. This post fills in some gaps for me. Thanks for the write-up!
