I literally just made a bootable live cd for nixos to boot into a browser on a whim for a test. I had 0 knowledge of this 10 minutes ago and 5 of those minutes was writing the iso to the usb stick. Nix surprises me again. And you can make any type of image you want... digitalocean, ec2, hyperv, vmware, etc. Its nuts:

NixOS
Nix is a tool that takes a unique approach to package management and system configuration. Use it to build reproducible, declarative and reliable systems.

Developing #Java with #Gradle on #NixOS and needing multiple or different specific #JDK(s) (toolchain versions) might be a tricky with NixOS, as it's not following FHS and installed JDK(s) aren't placed in standard Linux locations.
Sharing a configuration to be added/imported into `configuration.nix`, that makes multiple JDK(s) available in /opt/java, and therefore Gradle's JDK auto-detection picks them.

If you are using #NixOS, just use this configuration
```nix
{ pkgs, ... }:
{
services.orca.enable = true; # for screen reader
environment.systemPackages = [
pkgs.pied # only available on unstable at time of writing
]
}
```

Thanks to the awesome @leftpaddotpy and 9999years (I don't have their fedi?!), we now have #Lix 2.93.0: https://lix.systems/blog/2025-05-06-lix-2.93-release/.
The release notes contain a lot of goodies, nevertheless, another cool thing about it is that it contains a tremendous effort from eldritch horrors to rewrite the I/O and threading model to KJ: the Cap'n'Proto asynchronous runtime.
This unveiled a massive amount of hidden ordering constraints in the codebase, very hard to debug.

The video from my FOSDEM 2025 talk on "How reproducible is NixOS?" has finally been published! (it had sound issues before).
You can find it here: https://fosdem.org/2025/schedule/event/fosdem-2025-4430-how-reproducible-is-nixos-/
If you are interested, it is also based on a blog post: https://luj.fr/blog/is-nixos-truly-reproducible.html

I saw a post that Ubuntu 25.10 is switching to sudo-rs, which is a rust-based alternative to regular sudo. So I decided to do the same for my #NixOS install. All it took was:
```
security.sudo-rs = {
enable = true;
execWheelOnly = true;
wheelNeedsPassword = true;
};
```

Polish below / Polski poniżej, boosts appreciated!
I’m very glad to announce we have an official date for the next Nix User Group Poland Meetup! If you happen to be around Gdańsk, Warsaw, or Poznan on the 23rd of May, please come to either HS3, HSWaw, or HSPoz and join us for some great talks, great people, and great Nix. We’ll be starting at 17.00.
We coordinated between the three hackerspaces to connect them through streams, so any talk in any place will be appreciated from all 3.
We’re still open for more talks, so be sure to use the submission form or contact me directly if you want to share anything nix-related with our community.

I really like the easy way that NixOS enables you to get rid of all cruft through one config file. Discover, kwallet and elisa are part of the Plasma metapackage. Removing them in other distros gets you the warning that you, by removing them, are actually removing Plasma. Not so in NixOS. a clean working Plasma session remains, without those unnecessary addons. Re-adding them is one simple edit away.

Great fun I just had with Nixbook, a project by Mike @codemonkeymike , turning your computer in a Nix-powered Chromebook. Restarted 8 years ago with Linux Mint and have been on a great Linux journey since. and yes, I've done them all (except LFS and some other curiosa). Nice to be on Cinnamon again. Did Nix as well, and still had those configuration.nix files lying around. Don't really need them, all just works. Only switched a channel of course ;-) Check it out, it's a great one!
