They’re referring (I believe) to the screenshot right at the top of the article, which includes this absurd calculation:

border-radius: max (0px, min(8px, calc( (100vw - 4px - 100%) * 9999)) );

My guess (hope!) is that this is not ‘serious’ code, but padding for the sake of a screenshot to demonstrate that it’s possible to use each of these different features (not that you should!).

Don’t even need to remote in to anything, just store your working code on a network share

Not sure why people here are all arguing about why you would want to use discs, rather than the fact that the Steam Deck is a PC, of course you can absolutely used discs. All you need to do is plug in a USB disc drive, and it’s ready to go. I’ve installed a bunch of my older PC games from CD/DVD that way, and it works great. Even under Linux, applications like Lutris make installing Windows game discs pretty easy, and once they’re installed, you’re ready to go.

I use it as my only personal (i.e. not work or shared) machine, and it is absolutely great. I expected to be installing a ‘proper’ linux distro on an external drive for the docked use-case, and it has turned out to be completely unnecessary. For those things not available as flatpak, distrobox/podman has been great. (The only thing that slightly irks me that is missing is support for a printing service, but I haven’t tried that hard to fiddle with that, since I can do it from my phone on those rare occasions I need to.)

That shouldn’t be happening. I use mine as a desktop all the time, Firefox is pretty snappy, with a whole bunch of tabs open and extensions. Sorry I can’t give much more insight into what’s happening, but it’s definitely not right.
