Something like this:

Like I said, just make sure the latch hardware has enough clearance from the wall and you should be able to fit a 34" door in there. If you needed a 36" door, you’d probably have to either tear up the existing walls, or otherwise have something that looks a lot more weird.

You need the knob side to stick out enough for the latch to not hit the wall, but putting the jamb against the (finished) wall surface should be enough. Then use something like quarter-round as trim to hide any gap left from shimming the door.

You might want to bring a long level and see how plumb and even that opening is. The trim work will look worse if there’s a lot of variation in that wall, or if it’s not vertical. In that case, depending on how much you care about the appearance, you could tear off the drywall and adjust or shim the studs to have a better wall to work from.

If you end up with the trim looking uneven because of variation in the wall, you can paint the wall, trim, and jamb all the same color to make it less noticeable. It doesn’t look the best when you do that, but it might be preferable to seeing wobbly trim. And for a basement unit, it’s probably fine.

Might have the same issues as the barn door, but something like a pocket door might help maximize the width (assuming you don’t need access to that door under the other stairs). It would at least be a little better for noise.

For a more “standard” door, you could basically just install the door jamb right up to the existing wall. It would be tricky to trim it nicely, but you’d only need about an inch of space on each side that way. And if you’re careful, you can make it so the door can open almost a full 180 degrees into the basement to make it easier to move furniture.

Your other option for gaining space is removing the drywall/plaster from the wall of the stairs and replace it with paneling or something else thinner. Could get an extra half or three-quarter inch maybe?

It’s possible, but there are plenty of reasons an SD card can be slow. Not necessarily going bad.

If you can find a microSD adapter, you have plenty of options. The “server” version of raspberry pi OS is a CLI OS based on Debian. If you use the raspberry pi flash tool, you can even set up the SSH login details before you flash it so you don’t need to hook up a monitor or keyboard to the pi.

Is this the cast of Ocean’s 7 or something?

The lower six carry the team for most of the film. At the crucial moment, they’re all straining to crack the highest security system known to man, and just as the team is about to get locked out, the first guy walks in and types in the password. “Oh yeah, I sent a phishing email to the CEO before we started. Execs are pretty stupid.”

Nah, it’s just HTML and CSS, no scripting

Dang, you right

I got fancy and set mine to monospace
