I don't think the burial matters. It's not random atoms that are turned into C14. It's specifically nitrogen. And I think those interactions mainly happen in the mid atmosphere with cosmic rays. So it's the atmosphere providing the shielding.

The Wikipedia page for this explains it pretty well, especially the Physical and Chemical Details section.

    I don't think it's that the plants are controlling the ratio. I think it's that more C14 is being made all the time. And it only gets mixed into plants when they are living. Specifically it looks like C14 based CO2 is made in the atmosphere and then consumed by plants.

    I do perceive it as negative. I've curated my feed to be free of this kind of meme, and so it was surprising to me when it showed up on the poems community, and then even more so when it didn't seem related to the poem that was posted.

    I understand that it's helpful algorithmically to post something attention grabbing, but part of why I'm here and not on reddit is to try and be part of a community small enough that it's not entirely built on attention.

    I appreciate the (original?) poems that you are posting to this community!, but it's a bit frustrating when they are accompanied by an unrelated meme.

    Also, if these are your poems, please tag them with [OC] like the community rules require

    As a separate note, you definitely want to do testing/tuning with ironing disabled. It will hide a lot of the features/defects that you are trying to observe/tune away.

    Once things are working you can then tune the ironing

    Okay my new guess is moisture in the filament causing inconsistent extrusion, leading to the bubble on the surface. And also causing over extrusion.

    For the walls, your picture is a bit too blurry/low res to really see, but I get the vibe of over extrusion with the small part that's sticking up in the center of the perimeters in the lower right. Also the top of the anchors for the supports looked over extruded, with plastic kinda curling up at the top.

    Your new print is now definitely under extruded with those gaps on the top surface.

    I think flow rate is not the culprit here. Your bridges on the first print are also extremely suspicious. They should be solid lines, not the blobs you're getting. Something is wrong with the flow of filament out of the nozzle. Could be moisture or temperature or issues with the extruder. It's hard to tell.

    Your non-infill regions also look very over extruded. I'd try printing 20mm cubes with a variety of flow rates and see what happens. If you're using their profile, is it possible that the filament you have is larger than specified?

    edit: looking a bit more, things seem really blobby too. Something is not right. Is it possible the temp is wrong for this filament? What is it?

    To alkylate is to attach an alkyl group, which basically means attaching a saturated hydrocarbon chain to them, which is shown with the bendy things attached to the people in the image.

    I think you're thinking of alkal in the sense of alkaline, which is basic/high pH

    If you want to create a space that propogates permissions, then you there isn't a way to do that built into the spec. Because like the other person said, spaces are collections of rooms. They don't control those rooms.

    However, there are multiple bots written that can do something like what you want. Here for example. Essentially you make the bot the admin, and then only create rooms, etc, through it. And it will create things with the right permissions

    Edit: This flexibility in space vs room permissions can also be seen as a cool thing in some ways. It allows you to do some things that wouldn't be possible under Discord's model. For example, maybe one room of a different community is really relevant to your community. You can directly include that room in your space and then all of the space members can see it and chat in it without joining the other community. Or you can even include their entire space inside your space.
