I watched this talk (by Rafal Dittwald) a few years ago, but it still holds up really well. 😍
It does an excellent job of illustrating the differences between procedural, object-oriented, and functional programming.
A great and simple game example to clearly explain the concepts.

Tuple instead of Lists in Python:
Use a tuple instead of a list in Python when you need an immutable, hash able, and faster collection of fixed items.

I've asked this before, and I'm pretty sure I already know the answer, but is there anywhere on the #fedora build servers to monitor when a new #ostree #compose has completed? something like #koji or #openqa ? maybe with a diff list?

I just read https://lwn.net/Articles/1020571/ in which is

One thing that has been a bit of a pain point, Wick said, is that nested sandboxing does not work in Flatpak. For instance, an application cannot use Bubblewrap inside Flatpak. Many applications, such as web browsers, make heavy use of sandboxing.
.
They really like to put their tabs into their own sandboxes because it turns out that if one of those tabs is running some code that manages to exploit and break out of the process there, at least it's contained and doesn't spread to the rest of the browser.
.
What Flatpak does instead, currently, is to have a kind of side sandbox that applications can call to and spawn another Flatpak instance that can be restricted even further. ""So, in that sense, that is a solution to the problem, but it is also kind of fragile"." There have been issues with this approach for quite a while, he said, but no one knows quite how to solve them.

Notwithstanding the rise & rise of numerous #atomic / #immutable distros, which thus rely heavily on flatpak usage by users, i still substantially prefer "traditional" mutable distros, & native pkgs.

After reading this article, & attempting to understand it [not my area of expertise at all], i feel even more motivated to keep avoiding running any browser as a flatpak version.

Thoughts pls, from others who would certainly have a better understanding than i?

OK, what application do people use for #SDR with #HackRF on an #immutable container-based distro like #UniversalBlue?

I've tried the SDRAngel flatpak (can't get it to see my HackRF device) and the CubicSDR AppImage (doesn't include its dependencies in the image; won't launch). Went to build a couple of others from source and zomg the dependency hell. If there are other flatpaks or appimages that work, I'm all ears, but I didn't see too many on flathub.

Gonna try a VM next, though the HackRF docs suggest it won't work. Maybe that advice is stale.

I finally started building my own container image for #Fedora #Kinoite 42 with a `/nix` directory (only an empty directory).

Works. Only had to remove the dependency on the `nix-directory.service` from the nix.mount unit and now I have a populated /nix directory and everything is available again.

Question to the #fedora #immutable #silverblue #kinoite folks:

Since version 42 the root filesystem seems to be composefs. What would be the proper way to create a directory in this filesystem?

Asking for a nix systemd unit that now fails to create this, so there is no Nix store on my machine anymore... :-)
