With all do respect I think your over complicating the problem. It’s not rocket science (no pun intended). It’s essentially a hobby rocket that can be weaponized and it’s all DIY. That’s the point simple and off the shelf. Not meant to travel towards the stratosphere or even long range. Quick and dirty way to cause havoc in a localized area.

Ok. Maybe you are right. I don't know.

And also the attacker can send 100 drones without any real targeting at all and 10 proper expensive drones and you need to send up 110 defenders which need to be able to track flying drones. Being the attacker will always be easier.

Regardless, he made a prototype rocket enclosure and he seems to have the software down… I think the propulsion system will be the easy part. Hardest part will be tuning the PID so that the rocket goes where he wants it to. Then incorporating his tracking system will be another challenge of itself but that’s because of the form factor. As long as his calculus and linear algebra is good I see than being successful. Either way I’d hire simply to be a prototype engineer. Either Anduril or CIA would hire him in a heartbeat for prototyping.

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.

Literally the only thing wrong with these is the RAM is so borderline in 2026. 12GB would have been right on the money for an upgrade options.
FrojoS · 12 hours ago
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"

Why accept PR's in this case, if the maintainers themselves can ask their favorite LLM to implement a feature/fix an issue?
FrojoS · 6 days ago
Because it might require time consuming testing, iterations, documentation etc.

If everything the maintainer wants can (hypothetically) be one-shotted, then there is no need to accept PR's at all. Just allow forks in case of open source.

Dont listen to Söder, he ate too many sausages which makes him spout nonsense constantly.
FrojoS · 6 days ago
Söder merely repeated what Bavarians have been thinking and saying since when he still hadn't left Franken.

I realise my post was unnecessary inflammatory and I'm sorry for that. Enough Internet for today.

What gaga show? Bavarian industry is being subsidized via cheap electricity from the north, who in turn is paying higher prices than they would otherwise.
FrojoS · 6 days ago
Bavaria has been subsidizing the north for decades and yet you think you can betitle us? This is not just about electricity. We are talking about billions of EUR in transfers. The money is flowing one direction only. So called “solidarity” is a hard ask given this arrogance.

That does not seem to be a long term problem. Wind and solar can be down regulated with ease (and within fractions of a second), a negative prices only happen because producers got a flat-fee per kWh which is pretty much phase-out now. The problem is rather that Germany (plus Luxembourg) is still a single price zone, i.e when wind is blowing in Hamburg, the per-kWh price in Passau is also nill. While this is nice for Bavaria (the main culprit, as usual), there is an enormous cost for this in the form of re-dispatch fees as long as the grid is not strengthened a lot.

The main culprit as usual? They have been financing the whole gaga show for years.
