They're the same thing: de Broglie wavelength would be the closest thing if you want to assign an effective "size" to a particle.

If that cap didn't spreading the heat as well, what you'd be seeing on the thermal camera would be something that glows around 60C-70C (because clearly, the camera's software can more or less resolve the room temperature refl

CPU is at 23C? Are we looking at the same image? The CPU is the heat generator there, and is in contact with metallic regions around 60C (the red ring, if you compare to the real picture and follow the metallic bevels), where heat conductiv

Let me try again. Assistant Professor of Physics here (not a grad student). Yes, reflectance of room temperature aluminum at those wavelengths is pretty good (not true for all metals BTW). Yes, this usually makes it hard to distinguish ther

Except they're not, they're man-made laws. (I don't believe in any deity or religion but arguing on delusions is beyond the point.)

Ugh. So much noise. I was going to avoid this but I'll bite once. I'm a professor in condensed matter physics, doing research actively, quite well aware of Lagrangian mechanics and relativistic QFT, path integrals, and I also taug

Gitlab didn't have those extra features at early stages either (Gitea does have CI API BTW, if not a built-in CI). And Gitea doesn't have Gitlab's financial resources. But the point being made is orthogonal to the feature set

You're presenting a false dichotomy. There are CCTV cameras everywhere in Japan too (most of them are not operated by the government, but the government asks for footage when necessary), which is one of the safest countries in the worl

"long long" is proof that it falls apart. Short/long were descriptive, meaningful adjectives, and in the context of 3 integers of different sizes, it made sense. "long long" isn't a descriptive or meaningful

Yes, FOSS in GNU/Linux distros are still written mostly C/C++. And I don't think C/C++ is going anywhere soon. What I'm saying is, Go and Rust are very new, but gaining traction fast for new projects, despite their

I know what you mean, but one can say "which register", though. Intel CPUs have registers ranging from 8 to 512 bits these days.

I'd rather say having such ambiguous adjectives for types was a bad idea to begin with. And it falls apart when something longer than the original long comes out. I'm not blaming them for not being explicit about the # of bits bac

I don't have to know C# to run a Unity game on Linux, though. The fact that Unity has an "Export to Linux" button doesn't tell anything about the penetration of C#, as a programming language , in GNU/Linux communit

I'm not saying there are zero C# programs in GNU/Linux distro repos. I'm saying compared to its status in Windows world, it's a niche language with very low penetration. C# never got popular in Linux or BSD environments

It isn't redundant because that's the only type in Go which does that. There is no issue because int is explicitly defined to mean the CPU word. As I already mentioned above, due to how its meaning mutated and got distorted over t

x265 never removed film grain; you need to enable it via --tune grain option (or -tune when using it via ffmpeg). There's a new --tune animation option in 3.0 if you're encoding anime/cartoon.
