coremoff··on Dark pattern: how YouTube makes sure you don’t always “skip ad”
I think it only show "any random video with music" if you've liked the video and it appears to be a legitimate music video (i.e. without dialog/non-musical noises etc.). I use YtM a lot and the only questionable videos are ones that I've hit like on (beat saber being a prime example - I've learned not to like anything like that, these days).

coremoff··on I have no capslock and I must scream
I had a similar experience when I tried to learn Polish; my friends, who knew I was trying to learn, simply couldn't understand what I was saying, and couldn't guess either (and my ear found it very difficult to hear the difference between the expected pronunciation and what I was saying).

My heart wasn't really in it, but I was also very discouraged by this.

coremoff··on Ultrahigh-energy photons up to 1.4 PeV from 12 γ-ray Galactic sources (2021)
ah, thank you; I will correct above
coremoff··on Ultrahigh-energy photons up to 1.4 PeV from 12 γ-ray Galactic sources (2021)
Photons are massless and hence always travel at the speed of light.

Photons have a wavelength, and that determins their energy; photons of a same wavelength will all have the same energy; the photons discussed in this article have very short wavelength and very high energy (this energy is proportional to their frequency and inversely proprotional to their wavelength).

Regarding electrons; electrons have mass, and they all have the same mass. They have energy associated with this mass, and they also have energy associated with their momentum, thus they don't all have the same energy.

coremoff··on Google is wrong. Apple’s iMessage is a failure
this is my own experience too. Also in the UK

coremoff··on Is old music killing new music?
I have a subscription to YtM; I think it's great (though I think the user interface isn't as good as GpM was). Playing a radio based on a track I like is very good for discovering new music and bands - it has consistently given me an essentially endless stream of music that is different, but similar, to the chosen track; my subscriptions have increased dramatically in the last couple of years based on that.

Anecodtally, YtM seems to be better for EDM these days; my friends, who are mostly spotify, complain that they're not presented with the same quality and variety of music as I am via YtM. (EDM is just a portion of my tastes, but it's where I have noted a difference in perception between YtM and Spotify).

Sounds like Spotify works for you; if you're finding that "albums you might like" is giving you sufficient good new picks, then why change. If you feel that it's not giving you enough, it might be worth trying YtM (I've been using it for years, and don't know how much that impacts its ability to offer me new music I like, so obviously YMMV).

coremoff··on Astronomers discover a strange galaxy without dark matter
Not an expert; please correct me if anything is wrong.

My understanding is:

1. there needs to be somewhere to escape to, for the schwarzschild radius to make sense, and there's no "outside" to the universe

2. we don't know how big the universe is or what it looks like; if it's infinite and uniform then there won't be any central point for a singularity

3. as others have mentioned, inflation is a get-out-of-black-hole card

4. the physics of the early universe aren't necessarily the same as physics now

coremoff··on Busy Simulator: Feign importance with repeating app sounds
yes, it works for whatsapp; note that it does bypass Do Not Disturb, but won't make any noises if you've turned the phone to silent or vibrate.
coremoff··on Reality has a surprising amount of detail (2017)
the thing that I don't understand is why people think that there would be a simulation of a universe; surely it would be more likely that this is a simulation of "you" (well me as obviously you lot aren't real) - vastly simpler and more plausible
coremoff··on Reality has a surprising amount of detail (2017)
I've only watched the the first five minutes of that video; I think he has some fundamental misconceptions that make it difficult to take much from what he's saying.

e.g. for #2 wave/partical duality (which isn't necessarilly even a thing, depending on what foundation of QM you subscribe to) he says that everything is energy and that energy is light; this is not correct (the 2nd part)

for #3 energy is not necessarily conserved over long time frames in our universe

#4 depends on which foundation of QM you subscribe to, but doesn't necessarily require non-locality (AIUI, if your foundation results in this problem, then you must chose between locality or reality to explain things - reality in this context not really meaning what it might mean in common parlance)

#5 singularities appear in black holes because the maths breaks down because we don't have a unified theory of QM+gravity; they aren't magical. Also the big bang wasn't a singularity in the way he seems to be implying, again AIUI

I'm no expert, but I would suggest you review some more technical videos before reading too much into the link you posted (I suggest PBS Space Time / FermiLab / Sabine Hossenfelder)

coremoff··on Mysteries the Standard Model can’t explain
I don't know that it's a problem, and I'm no expert; my understanding is that differences like that can sometimes indicate that there's something else at play
coremoff··on Mysteries the Standard Model can’t explain
somewhat related, I think, is the enormous disparity between the strength of the strong/week/electromagnetic forces and gravity (30 or 40 orders of magnitude); possible indication that there's something missing
coremoff··on 1632 by Eric Flint (2000)
> if anyone else has any other recommendations in same genre of time travel and re-booting up civilisation

There's a couple that I know of:

https://www.goodreads.com/series/40821-belisarius https://www.goodreads.com/search?q=safehold&qid=

Flint was involved in the Belisarius series (along with David Drake), and Safehold is basically Weber's "reboot" of one of the books in his "Armageddon Moon" series.

If you liked 1632 you will probably like these as they're in a similar vein

coremoff··on Why salt was so important throughout history (2018)
For anyone interested, they do tours in several languages.

Additionally, the tours have two sections - the first half that everyone does, and then they offer you the choice of going back up, or going to the museum area; definitely worth spending the extra time (particularly as it seems few people actually do it, so you'll have a chance to actually speak with the guide in more depth).

I've been twice and would happily go again - couple years ago now, so maybe things have changed.

I really should curate my photos - I took hundreds :)

coremoff··on Superintelligence Cannot Be Contained: Lessons from Computability Theory
The lesswrong community has discussed this at length, though I think that the value is reduced somewhat by them refusing to release any transcripts of their simulated attempts (where a human pretends to the the AI and someone else is tasked with maintaining containment).

coremoff··on Watermelons
Without meaning to defend it too much, as I believe it's mostly a marketting/lobying thing...

As I understand it, the issue was whether or not you could count a pizza towards your vegetable quota. The argument came down to the nutritional content of the tomato sauce on the pizza; nutritionally, this was very similar to the requirements for other things that can be classified as vegetables, and so one portion of pizza was deemed to also count as one portion of vegetables.

coremoff··on Astronomers witnessed the death of a star as it happened
it's a big "if"; it's not possible for objects with mass to accelerate to light speed.

If you were able to do so, yes you could "get" anywhere in zero subjective time - as mentioned earlier, since no time passes for you, there would be no way for you to decide that you wanted to stop travelling at light speed - you would end your existence by impacting something.

> that certainly makes no sense to me

Humans, as a species, aren't experienced with relavitistic effects; we have no useful inherent intuition as to how things behave at these sorts of speeds. Most of us have to accept the maths and the experiements that demonstrate that our understanding of this behaviour is accurate.

coremoff··on Astronomers witnessed the death of a star as it happened
That is correct.

Obviously, given that, you would have no way of stopping, so your arrival would be abrupt (ignoring whatever magical affects would be necessary to accelerate a massive object to light speed).

coremoff··on Writer Liu Cixin on How His Visions of the Future Collide with Reality
> What could happen if the speed of light dropped to 16km/s?

I've not read the books, but I have read the synopsis, and when I read this bit I was somewhat surprised as there are so many things that break that new limit - would our electrical minds work at that speed? What would happen to electron orbitals? What happens to the stars orbiting the galaxy at ~200km/s ?

coremoff··on Tether is under undisclosed SEC investigation, FOIA blocked
Gary Gensler thinks crypto is part of their remit:

> The SEC has a three-part mission — to protect investors, facilitate capital formation, and maintain fair, orderly, and efficient markets in between them. We focus on financial stability as well. But at our core, we’re about investor protection.

> If you want to invest in a digital, scarce, speculative store of value, that’s fine. Good-faith actors have been speculating on the value of gold and silver for thousands of years.

> Right now, we just don’t have enough investor protection in crypto. Frankly, at this time, it’s more like the Wild West.

>This asset class is rife with fraud, scams, and abuse in certain applications. There’s a great deal of hype and spin about how crypto assets work. In many cases, investors aren’t able to get rigorous, balanced, and complete information.

>If we don’t address these issues, I worry a lot of people will be hurt.

coremoff··on An ultimate guide to memory palaces
thanks again.

> photographically document

I have aphantasia, so it's a little more abstract for me, but I can still walk around spaces and pin concepts to them :)

coremoff··on An ultimate guide to memory palaces
one more question, if you'll indulge me: do you keep a number of empty palaces ready for when you'll next need one, or do you create them on demand?
coremoff··on An ultimate guide to memory palaces
many thanks, that's really useful - I've been wanting/trying to sort out my memory for a while (I did use PAO for a while before it fell out of use, and I've used a small palace for trivial things like shopping lists), and this will really help, particularly:

> Later, I store "memories within the memories"

This is such a good idea - I had been thinking about many many different points in a single palace, which is a lot of work; this would make everything much more manageable.

thanks again

coremoff··on An ultimate guide to memory palaces
so many questions :)

> So I memorized books. Convert a book into 100-250 bullet points, memorize them in a memory palace

do you have one palace per book? Many bullet points per location? Very big memory palaces?

do you memorise as you read, or do you take notes and learn those?

any guides that you found particularly useful?

coremoff··on 2006: Dwarf Fortress
I haven't played much 5E, but they probably removed a lot of that when they simplified everything
coremoff··on 2006: Dwarf Fortress
don't know how it was fixed in DF, however that feels like a problem that was "solved" in DND; if you try and move via a medium for which you don't have a natural speed, you make a check - if you have a natural speed you don't need to make the check. Thus characters don't need to make "walking" checks, but they do have to make "climb" checks. Similarly fish have a swim speed, so they never have to make swim checks. In the event that your ability is impeded in some way (e.g. grease on a ladder) then you might have to make a check against your (normally not-tested) skill, which would be high for your natural movement modes.
