I think you may have misunderstood what I was saying. I was outlining an example where the outcome is favorable by all parties, but the principles used to arrive at the outcome differ. If I understand you correctly, you seem to be describing an outcome that wouldn’t be favorable for all parties.

I think the implications here is that the reasons it gets legalized can have an impact on the specifics of the policy.
Could you elaborate on what you mean?

And parents are held responsible if they give it to kids
Imo, only if it can be proven that the parent is being willfully negligent regarding the safety the child.
Also, if a product that claimed to be safe, but actually wasn’t, was purchased and given to the child, then this responsibility should fall on the producer only.
- Comment on BACK IT UP 5 weeks ago:
Yes, but it shouldn’t be legalized for the wrong reasons.
This is kind of an interesting thought, imo. If one agrees with the resultant policy, does the rationale used to get there matter? Perhaps it does in principle, but I wonder if it matters in practice. The end result is the same.

[…] ivermectin, hydroxychloroquine
I’ll be honest, I don’t really understand this one. I’d guess that this is likely some hold over grudge from COVID, but I don’t really understand why it’s still a concern to get, presumably, more open access to those drugs. Aren’t we long past that conversation? Feels like beating a dead horse.
- Comment on BACK IT UP 5 weeks ago:
[…] raw milk […]
I’d support this so long as the manufacturers of said raw milk could be held to account for harm caused to a consumer who purchased it under the belief that it was safe — likely, this would also mean that, if it isn’t safe, the product containing raw milk must otherwise display explicit warnings. I think a person should be allowed to take take their own risks.

I’m glad that it seems like the war on drugs is showing cracks. I completely support a move to legalize psychedelics.

Hypholoma fasciculare
Hmm. I at least don’t think that it’s fasciculare. The stipe should have a collar [1.1] (though, I question this as none of the images I see seem to shop a collar), which this doesn’t. The caps should be convex [1.1], which they aren’t — the babies are somewhat, but the mature one’s are wavy. From the picture’s that I’ve seen, the color is also off — they’re shown as more yellow [1.2][2], where this one is not yellow — the color of the specimens that I’ve observed is, in general, very different.

Are there softwares to simulate enough electronics and microcontrollers to learn?
It depends on what you are looking for. For a quick simulation to get a very rough, and more ideal, visual, you can use something like Falstad. But for anything more practical and useful, I’d recommend using SPICE. There’s lot’s of software out there that implements SPICE [2]. KiCAD offers SPICE simulation [1].

I want to try learning microcontrollers afterwards but I can’t afford to buy any IRL atm
The perceived expensiveness of things is certainly relative, but I would still argue that the hardware for microcontrollers really doesn’t have to be that expensive [1][2][3][4].

Yep! I’ve found that the case is possibly a little too cramped for my liking — I’m not overly fond of the placement of the drive bay hangars — but overall it’s been alright. It’s definitely a nice form factor.

It wasn’t a deliberate choice. It was simply hardware that I already had available at the time. I have had no performance issues of note as a result of the hardware’s age, so I’ve seen no reason to upgrade it just yet.

I don’t have any fundamental issue with emojis when they’re used to expand meaning or provide clarity. Eg you could use an emotive emoji to show/clarify the intent/emotion of something. Imo, using emojis in this way is no different than the practice of adding a “/s” to denote sarcasm. When they get annoying is when they’re used superfluously. If they serve no purpose, then it’s just clutter.

The Higgs mechanism gives mass to elementary particles. That is not to say that the total of inertial mass of a non-elementary massive object is due to the Higgs.
- Comment on Higgs Field 4 months ago:
To make it as simple as possible
Too simple, imo. It simplifies to the point of becoming incorrect.
Higgs makes it hard to push something.
One is called inertial mass (what we feel due to the Higgs mechanism)
The Higgs mechanism has been found to give mass to elementary particles only (short of neutrinos) [3]. This is important to note, as the mass of hadrons is far larger than the sum of their constituent elementary particles [4]. The rest, and vast majority, is found in the bound energy (eg the Strong Interaction) of the elementary particles (eg quarks) [1][2].
Regarding “Inertial mass”, I want to note the following definition for clarity:
Inertial mass is a measure of an object’s resistance to acceleration when a force is applied. [5]

Higgs makes it hard to push something. Gravity makes it hard to lift something.
The Higgs interaction contributes to both. Mass due to the Higgs interaction is a component of inertial mass, given that the Higgs boson gives mass the elementary particles contained within [3]. Inertial mass is a measure of an objects inertia (ie its resistance to acceleration when a force is applied) [1][2].
Note that the concept of “lifting” only applies in a gravitational field when a force is able to be created by pushing off of a surface — the resistance to the “lift” being created by the objects weight. If one is in free-fall, for example, the effects of gravity are no longer apparent given that one has no reference to the fact that they are falling.

the other is called gravitational mass (what we feel due to gravitational attraction between two masses).
I’m not sure exactly what you are trying to say here, but I suspect you are perhaps referring to the following excerpt(s) from Wikipedia:
Active gravitational mass is a measure of the strength of an object’s gravitational flux [1]
Passive gravitational mass is a measure of the strength of an object’s interaction with a gravitational field. [1]
I’ve personally never heard the term “gravitational mass” before, but it could be found from the above two statements, or more succinctly stated:
Gravitational mass is the “m” in F = GmM/r2 (Newton’s law of universal gravitation) [2]

They are usually the same so the distinction is usually ignored.
This statement is rather dubious. Simply put, there has simply not been found any empirical difference between inertial mass and gravitational mass. [1]

These terms get a little convoluted for me as my knowledge of them is far from well established. I don’t really want to get into what the actual “Higgs field” is, but, for the sake of the meme, the following excerpt from Wikipedia should suffice:
via the Higgs mechanism, [the Higgs boson] gives a rest mass to all massive elementary particles of the Standard Model, including the Higgs boson itself. [source]
- Comment on Higgs Field 4 months ago:
I was assuming that the image was confusing the term “weight” with “mass” (as both are equal on earth — give or take the variance in Earth’s gravitational field)). If weight was intended to be a separate term, then it’s just incorrect. Weight is the term given to the force that objects in a gravitational field impart on others when they are not accelerating (I mean not accelerating to mean the object is still with reference to the surface of the Earth) [1.1]. In SI, weight is measured in Newton’s [1.2] and mass is measured in kilograms [2].

- Comment on Higgs Field 4 months ago:
As far as my current understanding goes, the majority of mass derives from the binding energy between particles, and only a small amount is due to the higgs interaction.
