  • > I think the propulsion system will be the easy part.

    Really? I think rocket science is still not easy. Just look at how much nation states are spending on maintaining their liquid and/or solid fuel rocket programs. If they even have one, let alone both.

    This book might give some insights into the why https://library.sciencemadness.org/library/books/ignition.pd...

    Quote: "All this sounds fairly academic and innocuous, but when it is translated into the problem of handling the stuff, the results are horrendous. It is, of course, extremely toxic, but that's the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water —with which it reacts explosively. It can be It has recently been shown that an argon fluoride, probably ArF2, does exist, but it is unstable except at cryogenic temperatures.

    [...] kept in some of the ordinary structural metals — steel, copper, aluminum, etc. —because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminum keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes."

    Granted this is about a fuel that is AFAIK not used for MANPADs, but the joke about the running shoes could be made about most aspects of rocket propulsion.

  • Not saying you are wrong or the option shouldn't exist, but what specifically makes 8 GB too little but 12 GB sufficient? Planned obsolescence and software that is written with the idea that "8 GB is borderline in 2026" seems to be blame. But perhaps there are genuine limitations that 8GB RAM runs into. Certain AI models, rendering at certain resolutions maybe?

    My 8GB M1 Air is my daily driver for over 5 years now and so far it has worked out well. Sometimes, I have to replace badly optimised software for good alternatives. I hope that by the time that MacOS becomes unusable, Asahi Linux is mature enough to replace the OS rather than the hardware. I'm still on Sequoia and from what I've heard going to Tahoe would be terrible for the usability of my Air. So, no idea how much longer I will be able to hold out and if Asahi is ready now. It looks ok on first glance.

    Edit: On second glance it seems not ready at all https://asahilinux.org/docs/platform/feature-support/m1/ "Video Decoder: WIP"
