If you are not talking about Steam, which comes with Proton out of the box, I'd recommend to give Legendary a try. It's basically the same thing, but with non-Steam games. And it's very user-friendly, like Steam.
VM startup time can be skipped by saving state instead of shutting it down every time.
I would say the worst issue using a VM is with programs that need the GPU (e.g. CAD softwares or games), and software with aggressive DRM.
I use DDG for the privacy as well, but personally I think it works better than Google in my field (software development). The only issue I personally have with DDG is that it lags behind Google in terms of updates, I notice when searching for something that came out or happened only recently.
None, I use Docker for Linux, and Proton (Heroic) for Windows.
But if I had to pick a virtual machine: libvirt with virt-manager as a frontend, which uses KVM for virtualization.
For what it's worth, I always prefer being redundant if it makes the meaning clearer to a non-native speaker audience.
For instance I didn't know "pandemic" implicitly meant "global". In my ignorance I thought you could have a localized pandemic. But by saying "global pandemic" it makes it more obvious to everyone, including those who, like me, didn't know.
Also I'll personally keep saying "my phone had an LCD display" because it feels smoother than "my phone has a LCD".
Yes, you can develop in .NET on VSCode and the debugger works on Linux too.
There is a Docker version of SQL Server which funnily enough is equivalent to the enterprise version (rather than limited like SQL Express). You can use it for free as long as it's for development purposes only.
There is no SQL Management Studio though.
One option would be to use PostgreSQL instead. Entity Framework makes it almost free to replace the database anyways (unless you are doing some db-specific things).
There are some other minor annoyances or missing features, it might bother you; but depending on how you are used to work, you might not even notice. But, hey! you are on Linux now, you get all the benefits of a UNIX operating system, it will be worth it for sure, right? (Yes, imho)
As for gaming, I only do light gaming so I probably don't count. I use Heroic Launcher and it works wonderfully out of the box 50% of the time, the remaining 50% you can probably make it work as good as on Windows if you are persistent enough.
Oh, and sometimes some games run better on Linux than on Windows, but I would say most of the time they run a bit worse.
Signal desktop client is actually Electron based. And AFAIK, Electron doesn't run on Android, only on the desktop.
I work professionally from Windows, and as a hobby from Linux. My tool of choice for coding in .NET is Visual Studio Code (not FOSS, but there is a FOSS version which is just a bit more limited). It's not as complete as Visual Studio, but it's much faster, it has all the basic tools including a debugger, and it's much more customizable.
Also if you have never done it before, you might love dotnet watch which works with any IDE and lets you make realtime changes to your code while the application is already running.
As for UI, my personal choice is deploying a static website on localhost through Kestrel (it's less than 100 lines of code for a fully configured one), and then let the user's browser take care of showing the UI. You could use Blazor if you really want to use C# all the way, but my personal recommendation is to stick to web technologies such as TypeScript and React (using either Parcel or Vite to build your project). Making your UI web-friendly also makes your app cloud-ready, in case tomorrow you will decide that's something you need.
Finally, you can now deploy .NET apps as a single self-contained executable on all major platforms. But as already recommended by other users, I would keep adopting a web-first approach and go for Docker, and eventually Kubernetes. It's a lot of work to understand it properly though, so perhaps you can start studying this topic another day in the future.
Feel free to ask me anything if you have questions.
A less salty way to put it would be that the chart is missing two labels: "Original prompt" and "Poisoned prompt".
Apologies, but why would one prefer the fork over the original? Aren't they both FOSS anyways?
That being said, I never released a full Godot game in my life nor I did with Unity or Unreal Engine.
In my experience, a great portion of competitive multiplayer games work. Although I have to admit that I mostly play games meant to be played among friends rather than against strangers.
