Current Issues With The Qt Project - From The Outside Looking In
Qt mono repo : .. you could check out all submodules and simply use CMake to exactly achieve this. A mono repo also means that if I only use qtbase and declarative, I would need to have all submodules in there? - No

Why is building a UI in Rust so hard?
For e.g. if you’re writing a framework, you need to interface with Cocoa on MacOS to draw windows, which only provides an Objective C or Swift interface. You can look at the Qt source code and see how they do it: https://github.com/qt/qtbase/tree/067b53864112c084587fa9a507eb4bde3d50a6e1/src/plugins/platforms/cocoa

Fish (shell) porting to Rust from C++
That's because Qt 6 wholeheartedly converted to CMake for you. (At least it is better than qmake.) In order to support this Qt has this large battery of CMake files [1]. Qt is of course a clear outlier, but you can't expect the same level of support from every other library you want. My points about "anything exotic" still stand.

A GTK4 Firefox with Libwaita is the next step into the right direction (Please click on the link and upvote my proposal).
What are you talking about? Qt has GTK theme support built-in: https://github.com/qt/qtbase/tree/dev/src/plugins/platformthemes/gtk3

What is this "Portal" which keeps sending notifications when opening the Choose a diskfile window? Is it safe to disable the notifications of it, or will I miss important notifications?
This looks like the Qt bug solved by this commit: https://github.com/qt/qtbase/commit/acaabc9108dfe75530960cf8e3ec4f3602cd82e0

member function definitions should have been like this
Yeah, I'm sure it's completely unheard of. Oh except that it took me all of a couple minutes to find an example of that exact thing in one of the largest, most commonly used C++ frameworks out there.

Post-mortem of a long-standing bug in video Game Path Of Exile, which was caused by a stale pointer
I don't see any connect in https://github.com/qt/qtbase/blob/dev/src/corelib/tools/qsharedpointer_impl.h, and QPointer isn't a QObject (though I don't know if the latter is actually necessary for signal-slots). One (unreliable) way to test is to see if a QPointer fails to be nulled out when the QObject is blocked by a QSignalBlocker. Alternatively I'd set a data breakpoint on a QPointer and try it out. But I don't have the time right now.

Why is remote desktop slow when host monitor is off unless HDMI cable is used?
FWIW I had decent success with Xpra on Linux, and it's still being actively developed, e.g. the HTML5 client is considered stable now: https://github.com/Xpra-org/xpra/

Apache Guacamole: a clientless remote desktop gateway
I use xpra for similar purposes (https://github.com/Xpra-org/xpra/)
> Xpra is known as "screen for X" : its seamless mode allows you to run X11 programs, usually on a remote host, direct their display to your local machine, and then to disconnect from these programs and reconnect from the same or another machine(s), without losing any state. Effectively giving you remote access to individual graphical applications. It can also be used to access existing desktop sessions and start remote desktop sessions.

Firefox 121 defaults to Wayland on Linux
I want to move to the "future", but I use several firefox profiles via xpra in combination with xdotool based hotkeys. The fluidity with which I can control my different profile windows without a mouse and with which I can switch between computers with no lag with this setup is a big reason why I have stuck with a Linux desktop, so I am sad to see those super powers go away for no perceived benefit. I have tried Wayland several times now and don't notice any performance differences, just more bugs in Wayland.
`xdotool search` seems like it has been deemed a security issue for reasons I can't understand (if someone has hacked in to the point that they can even run such query commands, surely I'm already pwn'd). Maybe I'm oversimplifying it, but to me it's like being upset that someone who broke into your house can see the color of your curtains. The powerful feature set of X far outweighs these minor security concerns.
And it looks like xpra is facing huge issues switching over https://github.com/Xpra-org/xpra/issues/387 :(, I have yet to be as satisfied with any other free remote desktop software (paid nomachine is close but less scriptable).
I hope these aren't fundamental limitations of wayland, but the challenges seem steep.

Advice on getting a 16GB Nvidia card..
They all operate(d) their GPUs just fine. I'm a heavy user of VirtualGL + XPRA for remote graphics usage, which is a constant factor in my life and work. When they're not doing graphics of some sort, they're hunting pulsars in a GPU-centric compute mode.

FreeRDP: A Remote Desktop Protocol Implementation
I've long been a huge fan of Xpra https://github.com/Xpra-org/xpra , both because of its "screen for X" original focus (though now it supports shadowing an existing session).
There was NoMachine / nx / freenx but it always seemed to be a weird animal to me, requiring installation as a separate unix user, at least at the time.

Cool but Obscure X11 Apps
One of my favorite bits of software is Xpra [0], "screen for X". You'd run it and it would start another X server (start apps in it with `DISPLAY=:1 xterm` or whatever), and you would "attach" it to your running X server with `xpra attach`.
You can attach to e.g. `ssh://hostname/:1`, so I ran a firefox instance on a homelab server and attached to it from my laptop and my desktop to not have to bother keeping bookmarks, tabs etc in sync.

Alternatives To X2go?
I’ve used Xpra in the past to connect to a remote system for GUI stuff, but I almost exclusively use ssh because most of the time I don’t need to run a remote windowing system.

I want to (securely) remotely access my Pop!_OS desktop from my Pop!_OS laptop - what’s the best way to do this in 2023?
To add to this if you need to access graphical applications of an entire desktop environment you can use Xpra or MOONLIGHT (I suggest the second one if you want to game on the remote desktop or need very low latency in general), you can use both of these through a ssh tunnel (you need to enable this and X forwarding in the config) so if you setup and allow access to ssh correctly you can also use these without too much of a hassle.
