Looks like I’ve replied to you a few times, and sorry for the accusatory tone! Didn’t mean it! You did get me worried since I’m going to be used “bare metal” in my embedded class later this semester, and felt like I had gone insane not being able to find it anywhere. I was mostly just trying to convince myself this morning I wasn’t insane. I had thought it was the standard terminology. I do also need to caveat this that I am not familiar with whatever law OOP was referencing. I’m assuming it was one of the either baked-in surveillance or age verification things. Yeah, I’m with you and don’t really see a way out, unless we just step way back in time when we had less standardization and do bespoke everything. Cheers, and sorry for the tone!

I was use the pre-virtual machine usage of bare metal to actually mean “No OS.” You are just raw-dog running code on the machine.

That’s a good point about what the OS provides. I come from an embedded context, so often RTOS are not much more than a kernel that’s handling some basic threads and processor access. There was a really interesting talk at USENIX a few years ago (Usenix 21 keynote with Timothy Roscoe, I just looked it up) that was basically saying that a modern OS like linux, isn’t even accessing hardware and is just an OS in a system of OSs on a computer.

So you are not wrong about what you are calling bare metal, but that usage is more popular at the moment, but the older meaning of bare metal actually just means “no OS.” It’s still very common in embedded world. They are the same words, but do have different meanings.

I cannot find it at the moment, but about 10 years ago I had found a guy at Tufts (I think) who was publishing about actual bare metal (no os) single process machines that would run a server with nothing else. It was supposed to be helpful for security reasons. It was definitely whacky. I cannot find it because the server-farm usage of bare metal has taken over :(

I do now see that “bare metal server” is not going to be the right search term. Perhaps bare metal computing? I’m not sure. But what I am talking about pre-dates virtualization.

Edit: For servers, it seems the papers are calling it “Bare PC” Example: https://doi.org/10.1109/HPCC.2009.34

What you’re talking about would be called running a browser on “bare metal.” The OS is typically on charge of resource management between the various tasks. Access to the processor, storage, screen, input devices, sound, network. The os is a layer that mediates these devices. On bare metal you have to do ALL of that.

I’ve seen some interest in bare metal web servers in the past which some believe to be more secure. But I don’t think I’ve seen browsers on bare metal. There’s so much browsers need to do anymore. But anyways, bare metal would be the search terms you want to start using.

Edit: “bare metal” seems to have a newer usage for servers, so the papers I found were calling it “Bare PC.” Example: https://doi.org/10.1109/HPCC.2009.34
