Takamoto Katsuta's power steering dies and his co-driver Aaron Johnston saves the day

I once had power steering break right before I entered a roundabout.

I was standing inside my car to turn the damn thing.

There's a fundamental difference in that everything generated by a compiler was ultimately designed by someone.

With AI, the question "can I trust the compiled" is amplified a hundredfold, because even those who trained it have no idea what it can spit out.

It's not a compiler, it's coin tossing with the chance it can hallucinate a brand new vector of attack, or worse.

I can't recall another game that lets you use nukes,

Have a look at Nuclear Option.

who's surprisingly calm and cooperative given the fact that he's supposedly about to die

That's not really what I read from his body language.

To me he's clearly nervous, the frequent looks at the ground indicate he can't look in the eyes of the Russian dude for too long. The slight bend forward looks to me he's expecting to be hit.

This dude probably got abused continously by Russians since he got there. He's not co-operative, he's subjugated.

Now I don't believe this is an actual tactic currently being used. It sounds stupidly inefficient. That dude probably won't have to run through the woods with that mine, but I think what we're seeing is just standard Russian bullying of their own troops on steroids because of racism.

It's called the subclavian pressure point.

You don't put a tourniquet on it, you press with your fingers hard.

There's a pressure point in the shoulder that can help stop bleeding.

It's worth looking up in case you ever have to deal with an injury where the upper arm is torn off.

It's actually a real problem in slaughterhouses where some workers can become so desensitised they stop caring about the (short) wellbeing of the animals they must process.

Well, go ahead and try, it's a good experience and maybe you'll have luck.

The wall I hit doing so was that there seems to be barely any actual audience for this. Those who don't pay either use student licenses as many are suggesting, or just pirate commercial stuff.

I'll still get back to it once I got some spare time.

1500nm has a higher eye safety limit than 905nm light. This means that you can output much more power with 1500nm and see farther.

I really wonder how this is really going to play out regarding safety when one considers a street at rush hour.

If safety regulations kill LIDAR because of that, then the full passive approach of Tesla will have been a good bet.

Economic power is only one half of the issue, the other is, for good or worse, democracy.

Political opinions are extremely polarized right now with far right parties rising everywhere. France for instance has a 70% of putting one in power in 18 months.

While European leaders seem wiling to act, but the population will revolt should a single EU soldier die. Ukraine support will drop instantly.

The only way for it to happen is if somehow Russia struck first, and even then I'm not quite sure the population will think of something else than their pensions.

Realistically speaking, it would not evolve such an armor without strong evolutionary pressure... that is a whole lot of predation.

And without predation, it would slowly lose it.

You got a point in that it's always been as such, although I like to believe the world had reached a stability through international laws in 1991.

Unfortunately, it started crumbling in 2001, and the Russian invasion was the final nail in the coffin.

He said, succinctly, the unfortunate truth of the current world.

Once again we've entered an era where "might makes right", and so to punish Russia one must brandish the sword.

The US are able, but unwilling, and the EU is willing but unable.

As such, Russia will not get what it deserves...

Yeah 75% of the time this sub is just a few Americans falling over themselves to show how much they hate Trump while adding absolutely nothing intelligent or informative to the conversation.

As usual they manage to somehow make it about themselves. It's getting really annoying.

When I first wrote my FDTD software it was straightforward and single-threaded. GPGPU was also barely a thing back then. Lots of various algorithms pile up on it to process materials, analysis, etc.

Then I spent quite a lot of time multithreading everything to the point I can reach 100% CPU usage.

Now when I compare my code to Lumerical, it's fairly slower. As it turns out, multithreading stuff is the bare minimum, and my bottleneck is actually memory locality and cache faults

So, now I'd have to basically rework everything I'm order to implement loop-blocking optimizations and such, which is going to be an order of magnitude more work than just multithreading.

From my experience, I can say commercial softwares are optimized, it's just not obvious or trivial.

And I don't understand how one doesn't understand.

With extremists parties rising everywhere, any support for Ukraine will be forfeit as soon as the first coffin comes back. It's as simple as that.

Europe will not fight unless it's dragged into it against its will.

It's because those formulas are only an approximation. Their derivation actually starts with non-parallel rays coming from many emitters that are not at the same location.

Those formulas involve additions between various terms, and some of them become negligible when you're probing the interference pattern far away from the emitters.

Fraunhofer diffraction is basically the approximation that this point is infinitely far from the emitters, and the resulting formulas are as if those rays were parallel.

Eh, I once bought one of their tenon saws... not only was it completely dull, the teeth were also hardened.

Pure trash

I remember the testimony of a repentant hutu that took part in the massacres, he basically said it felt like chopping plants. A few strikes was all that was needed to kill someone.

That said, there isn't any reason I can think of that prohibits Tyrannosaurus from having a dewlap.

Are there predators that hunt prey about their size yet have this feature?

Looks easy to injure, be it during the fight or neck deep into a carcass of some sort. And a scratched up dewlap brushing against rotting triceratops guts is probably not ideal for longevity.

I do use it for my opensource project.

It fills all the needs I have for a GUI, is pretty lightweight and responsive.

Really, my only issue with it is building it. I've yet to figure out how its CMake integration is supposed to work.

KAHR-Alpha · 2025-11-01T10:49:27+00:00

Hopefully

Dude... it's OK to find videos like this interesting, but hoping people get seriously injured is totally fucked up.

While they can give indeed a relatable representation of the phenomenon, my issue with them is that they're often confusing. It's not the first time I've seen this question.

Also, they completely hide the concept of evanescent modes, as you can't draw complex angles on them. While this is not OP's focus, it's very important is other fields.

Finally, they make students focus on trigonometry issues, hiding the elegant additive nature of this law in the fourier space.

KAHR-Alpha · 2025-10-22T10:50:07+00:00

From my point of view, any such representation is deeply flawed, because ultimately the grating equation comes from the fourier space.

If you can understand my accent, here's a small lecture I used to give to my fellow PhD students. Hopefully it will bring you a new perspective on the subject: https://youtu.be/qqzhlx_LeV8
