  • Posteo is mostly just a deployment of RoundCube.

    Mind you, I do assume they have deployment scripts and code for handling payments and such, which aren’t open-source.

    I also have to say, though, a hosted service using open-source is *nice*, because they will hopeful contribute back to that, but it’s not much beyond that.
    You cannot know, whether they actually run the software that they publish in their repository, so auditing the open-source code hardly tells you anything about the trustworthiness of the actual service.



  • Yeah, I feel like Christians make a big deal out of life vs. death. Life is declared this super great thing that was gifted to them by their god. And death is described like an eternal departure into the unknown.

    Meanwhile, if you view things in a much more mundane way, life is just your atoms jiggling about. It’s not particularly bad, when they stop jiggling together.
    But even if you do prefer them being part of a pile that’s deemed ‘alive’, your left toe is probably gonna get eaten by a worm and brought into a field, where a plant will pick up the atoms and grow some seeds, which get carried by a bird into the next forest and so on. Your atoms will almost certainly be part of many alive piles of atoms going forward.




  • I mean, not everyone has to train their voice to sing low notes. If it’s just your natural range, you won’t have much choice but to sing bass.

    Anecdotal, but I’ve also had to be called back the one time I was singing in a choir, because I was too loud compared to the rest.
    To some degree, I imagine that’s a physics thing, due to having a larger (resonance) body and being able to push more air through the longer vocal cords. But of course, you also simply don’t need to be as present as the melody on top.






  • I’m not aware of any such example. I’m not an expert, so could be wrong and the terminology in the following could wrong, but just to give you an idea:

    • If the species are genetically too different, it can already be a problem that the reproduction organs don’t match. For example, human sperm can’t even try to inseminate a chicken egg, because the egg shell simply blocks it.
      This is a fairly obvious example, but even at microscopic scale, the sperm may not be compatible with the egg cell.

    • Then you’ve got the problem that the DNA needs to be combined in some fashion. If you’ve got a different number of chromosomes, that will cause problems.

    • But even if a successful insemination were to take place and a fetus develops, there’s a very high chance that the gene combination of e.g. a human and a chicken just does not develop into something that can survive. It might have a chicken heart in a human-sized body and just can’t pump enough blood to survive. All kinds of things like that can go wrong.

    In general, nature is messy. It does not care about our definition of a species. But yeah, the chance of inter-species offspring is just very low when the species are very different.
