Free electrons also emit blackbody radiation. Photon quantization has nothing to do with the energy levels of atoms. It is a very fundamental property of the universe - you can tell because the only relevant constant is planck's consta

It may not be possible to meaningfully answer this question in this case. If we're talking about something like fluorescence, there's a fairy clear point where one photon disappears and another appears. In a linear process like t

Haskell is sort of the base model option if you want real full-power FP, and not just support for some FP techniques.

Because they don't actually have "deterministic finality" in any meaningful sense. It's not possible. PoS is, as usual, vulnerable to attacks like grinding, and you can only paper over this.

When you eliminate all "archive nodes" (i.e. actual full nodes), it becomes impossible to trustlessly determine the longest PoW chain.

Ego is why some people feel the need to come up with narratives where the reason other people drive better cars than them is due to some moral failure, and not due to rational decision-making.

Not everyone's vehicular requirements are satisfied by a vehicle which is optimized for transporting human bodies to and from town. Many of us have professional or personal requirements which require e.g. the ability to move heavy equi

I looked into this in detail one time and my fermi estimate was that, if we banned trucks entirely, it might optimistically save like 40 pedestrians a year. It's clearly not worth bothering, just on the grounds that it would be polit

Last mile subsidies are super weird. I was looking at a property in montana in the middle of nowhere that had no electricity nearby, but had gigabit fiber. I called the ISP and it was cheaper to get phone+Gb than just Gb due to subsidy rule

You said "this is false" and then said a bunch of stuff that's entirely consistent with my (true) statement.

ICE cars are way lighter than EV cars with a reasonable range. It's not a cliche, it's a true constraint of reality, which EV enthusiasts decoupled from reality frequently seem to forget.

Should work fine. I personally avoided using a reverse proxy like nginx or apache because they tend to have a ton of vulnerabilities (check out the CVE database results for "nginx"), making them a security management headache.
