Well I upvoted the post so that people will see the comments!

You managed to get your money back?! How?

I think that’s an american thing. Besides, that money is long gone since I made the purchase several years ago.

I asked for a refund when they kept delaying shipment of my Librem 5. I was simply denied and that was it. They told me I could still choose to receive the phone, but I don’t want it since it’s a bad, practically useless product now.

I reported them in my country for it.

I don’t remember encountering the particular bug they’re describing. I was hoping it was about the behaviour of drag-and-dropping something into the browser, such as with those “drop a file here to upload”. I am often simply unable to make that work because instead of the thing being dropped into the webpage’s element, it opens the file in the browser instead, which is not really something I ever want to do.

Not to mention the problem of what life is even supposed to do beyond a certain point of development. The depressing fact is that there is a finite amount of knowledge to be gained, a finite amount of resources to harvest, a finite diversity of life to contend or thrive alongside with. Once a pocket of life in this massive universe begins to run out of things to do and stagnates, then what? What is there to think about; to feel; to experience?

There’s little point in exploring space if one know how this universe works. One knows the rules, knows all the ways it can play out, and there’s no surprise waiting on the other end of any venture one can imagine embarking on.

That’s my theory. The Great Filter is just depressive boredom. We don’t see other life because by the time a civilisation is able and ready to spend thousands of years travelling through deep space, they’ll have already lost any motivation they might have had to do so.

I suspect that there’s at best a very short window wherein a species is both knowledgeable enough to dream of space exploration and technologically capable of sending any significant amount of artificial constructions out there.

Not to mention that anything an alien species might send into interstellar space is unimaginably unlikely to be recorded exactly at precisely the moment they pass another lump of matter - especially if the window is as short as I fear.

This comment tells me that you do not fully understand reversible computing, thermodynamics, nor what I am trying to say. The snark does not motivate me to be patient or pedagogical, but I’ll still give it a shot.

By interfering with a closed system as an entity outside of that system (for example by extracting information by performing a measurement on any of its component subsystems such as the position or momentum of a particle), you are introducing a dependency of that formerly closed system’s state on your state and that of your environment. Now, by state I mean quantum state, and by interfering I mean entangling yourself (and your environment) with the system, because our reality is fundamentally quantum.

Entanglement between an observer and a system is what makes it appear to the observer as if the wave function of the system collapsed to a (more) definite state, because the observer never experiences the branching out of its own quantum state as the wave function of the now combined system describes a superposition of all possible state combinations (their (and their environment’s) preceding state × the system’s preceding state × the state of whatever catalyst joined them together). The reason an observer doesn’t ever experience “branching out” is because the branches are causally disconnected, and so each branch describes a separate reality with all other realities becoming forever inaccessible. This inaccessibility entails a loss of information, and this loss of information is irreversible.

So there you have it. You can never extract useful work from a closed system without losing something in the process. This something is usually called “heat”, but what is lost is not merely “heat”: it is the potential usefulness of the thing of interest. But it really all boils down to information. Entropy increases as information is lost, and this is all relative to an observer. Heat dissipation represents “useless information” or “loss of useful/extractable energy” as it concerns an entity embedded in a quantum wave function.

Reversible computing can not work around it because one simply can not extract information without irreversibly affecting the system. This is a fundamental constraint due to how, in quantum mechanics, once an observer entangles themselves with a system they can never unentangle themselves. I believe that from that single fact one can derive the impossibility of reversible existence.

A partial answer to your question is that there’s a minimum amount of heat necessarily radiated when doing computation, given by the Landauer principle.

Furthermore, I also do not think that we will detect dyson spheres, because if a civilisation wishes to hide, they won’t radiate heat uncontrollably by extracting all possible energy, but rather send that energy elsewhere, for example by dumping it into a black hole. But I could be wrong and such a civilisation might care more about energy than remaining undiscovered.

As I understand it, they are making measurements of an otherwise single isolated particle as it moves about in a controlled space, and the measurements confirm (yet again) that the measurement outcomes match the probabilities given by the Schrödinger equation, which means that it interferes with itself.

The language used may lead some to think that we now have images showing a wave-like particle, but again, that’s not something that can ever happen. What we have are boring old images of a single classical-looking particle, but the patterns they display tells us that quantum mechanics is very much at play in between the takes.

tl;dr:

Peter Schauss at the University of Virginia says the wave packet is such a well-understood component of quantum theory that the findings of the new experiment are not surprising – but they do show that the researchers had a high degree of control over the processes used to cool and then precisely image the atoms.

I’m not entirely sure what they mean by having images of their waviness, because that is not how it works. You can not measure a quantum wave, because it isn’t a “particle” wave but a wave-like distribution of mutually exclusive measurement outcomes. Taking a picture is the same as entangling yourself, which embeds you in the quantum wave function such that it describes all possible combinations of you ending up with every possible outcome.

Same problem, 1070, NixOS Plasma

While it’s possible that this is the case, we don’t actually know that because the people with the right skills aren’t spending a lot of time and resources on experimenting with new ideas and concepts unless there’s profit to be made from it.

Chances of coming up with an idea for a new kind of OS that will bring great return on investment in terms of profit and market share are very low, so entrepreneurs are spending their time thinking about more lucrative ventures.

If we lived in a post-scarcity Communist society where everyone is free to do what they feel is important and fulfilling to them, we’d be more likely to see new and novel ways of interfacing with computers (and technology in general).

But we don’t.

Edit: Also, operating systems are a lot of work.

There’s another thread just like this one posted 2 hours earlier in this same community, fyi.

Just gonna copy my comment from there:

The Isle is honestly pretty bad in many respects. In fact, it’s such a mess that I need to clarify which version I’m even talking about, because there is an OG version and an on-going complete rewrite, prompted by them having fired their only coder and no longer being able to understand their own codebase.

The OG version was special. It was very simple, quite buggy and in a constant, obvious state of plans-and-hopes (being EA), but it had a unique atmosphere - the only true survival-horror to date, as far as I’m concerned/aware (only rivalled by some of my experiences playing DayZ, back when it was still an Arma 2 mod).

Playing a herbivore, resting/hiding in a bush in the pitch-black darkness of night with only limited night-vision letting me see my immediate surroundings and footprints on the ground, the sound of a massive, rumbling carnivore sniffing for traces of food was quite a thrill. Not to mention the moments after when a pair of jaws around my size suddenly emerge out of the darkness.

That kept me playing.

Then they stopped working on that and began their rework from the ground up. The rework (which they call EVRIMA) has (or had) no day-night cycle (always daytime), went from being set in an arboreal environment to tropical jungle, and had two playable dinosaurs (one herb- and one carnivore) of about equal size. No creepy nights, no asymmetric gameplay, no horror elements, different feeling in both how it feels to play and how it looks, and it also ran like crap on any device.

They’re slowly working on it; it has some more dinosaurs now etc, but last I played, it still didn’t feel the same and it was still buggy and severely incomplete. What emergent horror elements one might get out of the reworked version I feel are but shadows of what could have been.

And yet there’s none other like it.

Edit: I believe the current version does have night-time, but it doesn’t (or didn’t until recently) have night-vision and IIRC the nights are not as horrifying.

I don’t mind being able to see stats, either. I don’t mean to complain about this project; I fully support the author in modifying it to their preference. Just that I wouldn’t expect a “minimalist fork” out of this particular app. Regardless, it’s not unwelcome in any way!

I saw that but that just seems like their preference. I don’t feel anything in particular about the home page. It’s customizable too IIRC. I don’t know what the echo page is.

Cool if this is more efficient, but is AntennaPod considered bloated? It’s one of very few apps I feel give me precisely what I need and doesn’t annoy me with fluff.

Because they have no basis on which to decide where to go. It’s like buying toothpaste but there are hundreds of options, none of which you know anything about, so you get whichever seems most popular. It minimises the risk of ending up with something which is unpopular for good reasons.

While all of it is doable, be aware that it takes time and effort to learn Nix and NixOS. It can be difficult to figure out how to get a particular environment set up properly. There is a lot of documentation, but it doesn’t always give easy answers if you have specific requirements for a particular dev environment and such.

It’s been a few years since I worked with Unity3D professionally, but I did so in NixOS with very little trouble. Rust has very good Nix infrastructure and so do many other languages. I can’t tell you anything about UE5 or the other proprietary tools, but there are FHS-compatibility helpers (steam-run usually works fine when I need to run arbitrary binaries made for ‘normal’ distros).

If you’re willing to figure things out sometimes (and especially in the beginning) and are motivated to take your OS to the next level, NixOS is definitely worth it. Been using it for many years and I can’t imagine ever using a mutable OS again as a daily driver (unless the way I use my computer drastically changes). I configured everything just the way I want it; it’s magical to have almost everything in one place and being able to try different things without fear of breaking something.
