As per https://blog.gtk.org/2024/01/28/new-renderers-for-gtk/ and https://www.phoronix.com/news/GTK-4.16-Released :

You can still use either a new OpenGL renderer or the old OpenGL renderer. This can be set with the GSK_RENDERER environment variable (e.g. GSK_RENDERER=gl)

I would assume it will also probably detect unsupported hardware and switch to OpenGL automatically but I don't have any source to back this up.

TLDR: /usr stands for user

/srv stands probably for serve. (Source)

I'd just like to interject for a moment. What you're refering to as Taste, is in fact, Nutrition/Taste, or as I've recently taken to calling it, Nutrition plus Taste. Taste is not an operating system unto itself, but rather another free component of a fully functioning Nutrition system.

The extension is probably not broken because of Firefox but because Flatpak's sandboxing prevents it from talking to KeePassXC.

Nice

I believe this is Steve Huffman (aka u/spez) the co-founder and CEO of Reddit. (wikipedia)

This controversy is what this post is most likely referring to.

The title is perhaps a bit misleading. It's not a version of ChatGPT. At least not in the sense that it's a version of OpenAI's ChatGPT.

According to their GitHub:

gpt4all: an ecosystem of open-source chatbots trained on a massive collections of clean assistant data including code, stories and dialogue

It's an ecosystem. They seem to have GPT LLMs (Generative Pre-trained Transformer Large Language Models) and a chat app to interact with those models. Also they say that the models can be run on consumer grade CPUs (this is where the locally hosted part comes in to play).

I suggest you read the original review the article is refering to. It's more detailed and very well.l written.

I don't know about DLSS specifically as I don't have a Nvidia GPU but AMD FSR works fine as long as you use a somewhat new version of Proton. (And FSR isn't limited to AMD GPUs)
