  • Everyone is talking about dominant and recessive genes, so I just want to clarify a couple things.

    The way your body directly uses genes is as a blueprint to construct proteins. Your cells are always producing proteins from the genes in all your chromosomes. It has complex ways of regulating how much of each it produces, but your body doesn’t care what chromosome it’s coming from. Once an embryo is fertilized, there’s really no distinction between “mom” chromosomes or “dad” chromosomes, as far as the embryo and its protein machinery are concerned.

    “Dominant” and “recessive” characterization is about how those proteins affect your body at the macro scale, not whether your body actually uses the gene and produces its proteins – it always does that. For example, brown hair is a dominant trait, and blonde is recessive. But this is because producing any amount of brown pigment will make your hair brown, regardless of what other pigments you’re making, simply because it’s darker. Literally the same as combining blonde and brown paint. It has nothing to do with whether the genes are actually being expressed – the brown hair gene doesn’t stop the blonde hair gene from making its pigments.









  • Now you’ll have a zillion users trying to install software in ways that violate all the assumptions that NixOS operates on, but which are still tightly coupled to your NixOS config. Now updates to your system, or even seemingly unrelated config changes (through some transitive dependency chain) can easily break that software.

    So now we’ve basically removed half the advantages that motivate Nix/OS in the first place, and when stuff breaks it will look like it’s Nix’s fault, even if it isn’t.

    On the other hand, nixpkgs is already the most comprehensive repository of system software out there, and for 99% of packages Nixifying it is pretty trivial. Hell, my NixOS config does that for 3 different GitHub repos right inline in my config.nix

    Not sure about 1, but 2 and 3 both have the same answer. Both TSInstall and Mason are just trying to install other software packages on your system, and you’re on NixOS, so of course they can’t do that. You don’t install your software, you declare it. Add the Treesitter parsers you need right next to your plugins (there is a sub collection under the vimPlugins collection just for Treesitter parsers), and put whatever Mason would be installing into your user packages instead.

    That said, I agree with the other commenter. Even though the community has done a lot of work on rich config options for Neovim, they’re just too far away from the normal way of doing things in the Neovim world, and plenty of plugins are written in ways that assume it’s configured in “normal” ways. Plus configuring Neovim is already kinda like assembling your own car from parts in any case, so it’s honestly better to just use nix to install Lazyvim or whatever flavor of choice and let it handle the plugin management/config. And believe me, I really tried to do it all in Nix, I wanted to do it that way. But it’s just not worth the headache at this point






  • So, let’s put aside for a moment the rather shocking number of people casually advocating for murder in this thread.

    I want to talk instead about how everyone here is just talking for granted the notion that removing the billionaires, Republican politicians, or whatever “they” you care to think of, would be a solution, or even a positive step, for modern social ills.

    There’s a big undercurrent in almost any political discussion online, this implication that every one of the world’s problems actually has a super simple solution, that The Powerful could just snap their fingers and make it happen if they wanted to, and it’s only because of their greed etc that we have any problems that all. Obviously we live in a time of huge inequity and we’d be a lot better off if we found a good way to improve it.

    But many (most?) of our biggest problems are inherent to the challenge of keeping 8 billion people alive and happy in a hostile universe, and in fact nobody has ever had a perfect solution. Throwing the entire planet into chaos by causally throwing away human beings’ rights and leaving an enormous portion of the world’s capital in uncertain hands, ready to be seized by some other set of psychopathic opportunists who happen to be in a position to do so, certainly ain’t it.
