  • Like you said, there’s a metric ton of steps involved in the overall process, and our understanding of each of these ‘levels’ of organization varies quite a bit. Closest to my personal expertise is the sub-cellular and cellular level, for which I would refer you books or papers in developmental biology, developmental genetics, and epigenetics. I can give you a couple bloopers to get you excited though:

    When it comes to deciding where different organs will form (again, from a sub-cellular level), it essentially starts from a concentration gradient of certain proteins/chemicals inside the zygotic cell. This gradient then determines the level of activation of other proteins, each level then leading to different biochemical cascades which, once more cells have formed from the zygote, determine which organ systems will come from them. Messing around with this concentration gradient can, thus, dramatically affect an organism’s development, leading to, for example, a body with just ‘left’ organs on both halves, just ‘top’ organs on both halves, missing an entire organ system (like circulatory system and heart) and so on.

    A more or less similar process occurs to determine the shape of organs. As a simple example, when some animals with regenerative capabilities (like axolotls) lose a limb, they are able to regrow the limb to the exact same length as before. Turns out, each cell on the periphery of their limb has a certain concentration of receptor proteins on its surface, which acts as a molecular ‘signature’ of that cell’s position in the limb. These signatures provide information on how far to grow the limb for regeneration, and some chemicals, lile retinol, can even override these signatures and fool the organism’s body into regrowing the limb from scratch on top of the place of regeneration.

    I hope these examples give you an introduction to the mechanisms involved. There’s obviously a lot more involved, so I would again highly recommend textbooks and research papers if you’re interested.









  • It’ll get more complex than that. I’m no expert, but I’m guessing you have to consider the depth of the crust at your location, type of soil and the distance from (and time since) the last closest volcanic eruption, possibly distance from the nearest tectonic boundary, maybe even tidal forces (assuming they have a considerable impact on magma being pushed out, but this may be a bit too far)



  • A flair-like implementation would be nice for certain communities. From past experience on reddit, I can see how it could be beneficial to filter a community’s posts through tags, say, to check latest announcements or new support questions. I’d personally prefer community-specific tags as opposed to global post tags (which is what I inferred from this post’s content, I haven’t read the RFC yet though) edit: the RFC talks about both instance-based tags and community-based tags, which is even better



  • I’ve been using it for a couple weeks but haven’t used RCS, so I can’t say specifically about that. Overall though, it’s still a work in progress and is not as polished but it gets the job done (more or less). If you’re really concerned about privacy using their closed source app, you can just host your own bridges in your Matrix server (the app is the only proprietary part of Beeper, the protocol is just Matrix). The app doesn’t support logging in from another Matrix account, so you’ll have to stick with Element (I think Element derivatives would work too) when using your own bridges. But that’s probably a better option given that their own app lacks a few features.
