  • I would say “debunked” in the sense that quantum mechanics correctly predicts phenomena that don’t exist in classical physics, and relies on the idea that quantum particles obey a probability distribution, rather than deterministic mechanics.

    Quantum mechanics appears to work so well for these phenomena compared to deterministic mechanics that it’s tempting to say that the actual universe is in fact governed by probabilities rather than determinism.

    I would argue that all physical models of the universe are just that: Models. We can get asymptotically closer to a perfect description of the universe, but no model can ever tell us the true nature of the underlying system it is describing, just be an arbitrarily good description of it.





  • Just do a quick search for “mushroom cloud”, and you’ll find that all this combined is nowhere near what a nuke would look like.

    The mushroom cloud formed from a small nuke like little boy (small by modern standards) reaches up to about 8 km. that’s close to cruising altitude for an airliner. The reason the cloud from a nuke “mushrooms” in a different way than conventional munitions is that the intense heat is causing enough hot air to rise to form a literal cloud when it reaches high enough that the humidity condenses. This can even cause radiative rain shortly after the bomb has gone off.

    The fireball of Little Boy is estimated to have been almost 400 m in diameter with a surface temperature approximately equal to that of the sun, and every building within about 1.6 km was instantly completely destroyed.

    It is difficult to comprehend just how much more powerful even a small “tactical” nuke is than any conventional weapon. There’s a reason soldiers that were shown blast tests of them during the Cold War have told stories of breaking down crying at the sight, because they just couldn’t fathom what they were seeing.

    There was no nuke blowing up here.

    At this point I really can’t understand what is driving Orban anymore. He obviously must have known this would happen, and is likely doing it on purpose so that he can point at the EU as the “bad guy” back home, but like… what does he gain from this? Isn’t it better to just get a shitload of free money from the EU that you can funnel to your friends and family than to not do that? If he legitimately dislikes the EU he can just leave.

    Maybe he’s just sticking around as long as he can grab cash? It kind of seems like he’s going for the “see how far you can push it before you’re kicked out” play. Essentially trying to find out how much of an obstructing, law-breaking, corrupt asshole he has to be before the rest of the EU finally has enough and kicks him out, at which point he can peace out to some safe-haven (I’ve heard there are spare rooms in some of Putins palaces).


  • Awesome to see the effectiveness og the Gepard like this. It seems perfectly suited for these kinds of slow-moving low-cost targets that you really don’t to send expensive interceptors at.

    Especially when the leading drone tactic seems to mostly be “send enough to saturate the air defences”, having stuff like this that can rapidly burst down a bunch of drones at low cost, using ammunition that’s quick and easy to produce, seems perfect.




  • For someone starting out, I would say that a major advantage of Python over any compiled language is that you can just create a file and start writing/running code. With C++ (which I’m also a heavy user of) you need to get over the hurdle of setting up a build system, which is simple enough when you know it, but can quickly be a high bar for an absolute beginner. That’s before you start looking at things like including/linking other libraries, which in Python is done with a simple import, but where you have to set up your build system properly to get things working in C++.

    Honestly, I’m still kind of confused that the beginner course at my old university still insists on giving out a pre-written makefile and vscode config files for everyone instead of spending the first week just showing people how to actually write and compile hello world using cmake. I remember my major hurdle when leaving that course was that I knew how to write basic C++, I just had no idea how to compile and link it when I could no longer use the makefile that we were explicitly told to never touch…


  • it would seem crazy to sacrifice it if it wasn’t damaged

    To be fair, the best kit you’ll ever get is the right kit at the right time. If what you need is a tandem warhead that can track, hit and destroy pretty much any vehicle, or punch through a bunker, at anything from a couple hundred meters to a couple kilometres, and you have a Javelin… you’re in luck! On the other hand, if what you need is a tandem warhead to destroy a static armoured target that you can’t get line-of-sight to, and you have a Javelin… You’re carrying a very expensive but useless rocket and tracking system that just happens to also contain the exact warhead you need.

    Once a piece of equipment like a Javelin is in the field, it’s only real value is in whether it can help you achieve your objective. Its dollar value seizes to be of relevance. The only relevant questions are “Do I have a large enough supply of this munition to prioritise using it for that target?” and “Do I have another munition that I can and should use instead?” If the answer is “yes” to the first and “no” to the second, you use the munition in whatever way is most practical.
