No, it is not a proxy for another search index/engine.

Yes, you can add Brave search to your other browsers.

Operating systems can function very different. When creating software (like video games) the developer has to understand or use software dependencies which interact with the OS in a number of specific (OS dependent) ways. Stuff like where is app/user data stored, how to connect to the internet, how to display stuff on the screen (2D), how to display complex 3D geometry on the screen fast (3D graphics acceleration), where the host OS stores shared libraries (and what kind of libraries can the software expect to always be available), what security restrictions the host OS has, what filesystem the host OS uses, how to access the keyboard and mouse, how to interact with the kernel (very important).

Since Windows and Linux are so very different, built for different purposes by different developers, it is impossible to take a Windows exe and run it on Linux.

These days, the WINE project, with help from Valve’s fork Proton, is able to run basically any Windows game on Linux with similar performance (if not better because Linux is lighter to run than Windows). It does this by creating a environment for the software/game that provides all of the OS stuff Windows software expects and translating it to Linux specific things.

TLDR: Linux is very different from Windows. Software meant for Windows won’t work natively on Linux (since everything is different). For Windows software to work on Linux, the WINE translates all the Linux specific OS stuff and creates an environment for the Windows software that feels like Windows. Most things work with WINE except exceedingly complex stuff, like browsers which have native Linux versions anyways.

Thanks for some updated context.

What do you mean secure by design? What part of it is secure. Compare it to actually security focused Linux operating systems like QubesOS, Kicksecure, or Secureblue. Literally any OS that supports the Brace tool (made by the creator of DivestOS) is much more secure than Kali Linux. Kali is purpose built for red team work, not being secure (aka reducing attack surface or designing around a threat model).

You mention “sane defaults”. That might mislead someone because it is ambiguous. The terminal defaults used to default to a root prompt, exemplifying that it isn’t a distro focused on sane defaults for a desktop distro.

Kali is a tool for a specific job. Its meant mostly for hacking or troubleshooting/analysis, being an OS for executing a collection CLI/TUI and GUI utils.

-Edited everything to make myself more intelligible.

It isn’t a secure operating system. It is a toolkit for pen testing and red team hackers. Definitely not a daily driver kind of OS.

Basically, its a customization of Fedora Workstation with Steam, Proton GE, and some system tweaks for better gaming support.

I wouldn’t stress much. It would take a targeted attack to have actually compromised your phone. It is alright.

For good out-of-the-box nvidia support, I recommend Bazzite.

For nvidia hardware, use nvidia images of Aurora/Bluefin (or Bazzite if you want gaming out of the box). All the OSes I mentioned are based on Fedora Atomic and offer image options for nvidia proprietary drivers. They even signing the kernel drivers, so you can use Secure Boot.

Docker is good when combined with gVisor runtime for better isolation.

Sydbox OCI runtime is also cool and faster than gVisor (both are quick)

Really fun/interesting read.

Nyarch honestly looks like a joke distro and most of its features are not worth IMO.

I used Tumbleweed for a long time as a daily driver and then as my admin workstation. Worked really well, GUI admin panels are nice, and I didnt find anything too difficult.

The weakest link of any secured system is the user. I know that will never change, especially as computers/software become more complicated over time. But I don’t understand why many people argue that “since the user is the weakest link, we don’t need more secure systems, we need better users.” We need both.

X.Org server has been largely abandoned by maintainers and developers.

I would agree but it still heavily relies/requires X11 for many of the core components and apps. Wayland support on the horizon. For now though I wouldn’t recommend anyone use any DE that doesnt support Wayland, since X.Org is has been unmaintained for many years, it is a bloated protocol, and is insecure by design. This is because it was designed 40+ years ago in a time before security was a big concern to developers.

I recommend GNOME from a purely security perspective. Currently, “GNOME is the only desktop that secures privileged wayland protocols like screencopy.” It also has a nice permission system for (dis)allowing microphone, camera, and location access. I wish the developers were more open to encouraging customization of the certain GUI elements, like KDE. KDE Plasma does not protect against screen capture, though it is on their radar.

Canonical, the owners of Ubuntu, love to steal open source projects. They’ll help a project with development power, then force the contributors to sign a CLA (for an example see the fork of LXD called Incus). Canonical also uses and forces proprietary systems onto the user’s, e.g. Snap uses the proprietary and hardcoded Canonical repository, which Ubuntu now defaults to using Snap for installing packages.

Side note, if it wasnt for Snap using a proprietary backend and also depending on AppArmor (generally regarded as a weaker MAC than SELinux), I would prefer Snap over Flatpak. It creates a better sandbox (aka the actually Security of the software), avoids sandbox escapes, blacklists against broad permissions (e.g. $HOME access), and Snap packages generally have stricter permissions (which determines the real-world security of Snap). Sandboxing is very important for Desktop (and server) security. Android is does the best job of this, but it would be nice if projects like Sydbox, Crablock, or Bubblejail were adopted and built-in to the package manager.

But even without any of the previously mentioned problems, I just think Fedora is a better OS. Fedora comes preconfigured with SELinux policies to confine system services they are quicker to adopt new technologies. Fedora is also a semi-rolling distro, meaning packages are quicker to get updated than on Ubuntu. Fedora stays FOSS, where as Ubuntu becomes more locked down. Also, the package Brace made by the developer of DivestOS is great for quickly hardening a Fedora system.
