qsdf38100··on The brain simulates actions and their consequences during REM sleep
It reminds me of some talk I had the chance to come across, I can’t remember which one. Sleep could be a training phase. Discerning whether inputs come from the real world or from the trained neural network itself would be the reward function. When it’s no longer possible to discerne reality from "fiction", the training is complete. And this could be somehow linked to the ability of training while simultaneously operating the network. I wish I remembered where I heard about it.

Edit: I think this was it: https://www.youtube.com/watch?v=FBkhbqrFyo4

qsdf38100··on Tensors, the geometric tool that solved Einstein's relativity problem
In your cube example you are using the word "vector" to refer to faces of the cube. Did you mean matrix?

My understanding is that the cube is a rank 3 tensor, the faces (or rather slices) of the cube are rank 2 tensors (aka matrices), and the edges (slices) of the matrices are rank 1 tensors (aka vectors).

qsdf38100··on SpaceX accused of dumping mercury into Texas waters for years
SpaceX saying that SpaceX did nothing wrong is a start, but it would be nice to get the same kind of refutation from more independent sources.
qsdf38100··on Captain Disillusion debunks David Beckham beach kicks [video]
I was very happy to see a new video from him. It has been ages. I highly recommend the one debunking the magic trick with the card, the glass and the monkey. As you said, it’s much more than a debunk, he even went to the place where it was filmed.

> If the mind was purely matter, these fundamental building blocks for knowledge itself would be inaccessible.

The potential implications of this take on consciousness are fascinating.

This implies that a perfect computer simulation of a conscious brain would not be conscious, but only appear/pretend to be?

Where does your consciousness come from then? Was it hanging around and jumped onboard your brain when it developed? Will there be enough consciousness units available if we reach 15 billion world population? Or maybe those can reproduce or come into existence from nothing? Hmmm, so they can be created but never destroyed? So are there actually trillions of consciousness units wandering somewhere, like a memory leak for minds? Or maybe it's all about reincarnation, but, what if the earth is vaporized by colliding with another planet? In what beings would all these consciousness units reincarnate into? And what part of you comes from your consciousness in the first place? Is it some vague perception/awareness of existing? Or is it your full mind, with memories, logic, langage and emotions? But then what is the brain doing if it's not the processing supporting these features of the mind? Is it some kind of antenna for beyond-physical communication with the actual non-physical mind? But then what makes the matter in our brain able to perform this communication, special? Could we figure this out and get beyond-physical communication in the lab?

Sorry for this wall of questions, it's just... much more fascinating than the usual boring explanation, where the brain, neurones, axiomes and impulses allow information to flow and be processed so that you can form thoughts and reason about the world and yourself, and where all that processing stops with death and that's it, what was emerging from it can't go on without it.

It is not only a boring description of what happens when you die, it is also very disappointing. I would love for some grand cosmic resolution to my life. But I have troubles believing that it's actually real, as nice as it sounds to me. Wishes of reality, reality of wishes.

> If it's really all that dull, people will just take up extreme sports such as juggling honey badgers or naked skydiving over active volcanoes.

That, or... I know that'll sound crazy but... not everything has to be an adrenalin rush. Just let go, stop taking your keep-me-alive-forever medication, have a peaceful death during your sleep, contemplating the fact that you'll make room for new humans to have the chance to discover all the things you also had the chance to discover during the last 231 years?

What is it you suggest we can change with chemistry? Is it boredom? Are you suggesting we can keep enjoying the things we are bored with thanks to LSD or something? So, a childless world with centuries-old people drowning there boredom in drugs?

Please tell me that's not it.

Being old is not limited to how you look. It’s also how your world views change, how your personality evolves, etc.

Also you didn’t address my almost-no-children point. That one I think is the stronger point. Looking at my children grow older day after day is the thing that bring me the most joy and sens of meaning in my life.

qsdf38100··on In ‘The Book Against Death,’ Elias Canetti rants against mortality
Do you know about exponential growth? If birth and death rates are not about the same, it means the population will double every X years. You’ll need a major breakthrough in food production every X years. For ever.

Even if we achieve that, at some point there just won’t be enough square meters on earth. But I guess it’s okay to you since we’ll have solved space travel and we’ll just send billions of people to Mars? Then other planetary systems? Then other galaxies?

In any case, as I don’t buy we’ll ever be able to send billions of people to other planets, let alone make them habitable, this is exponential growth with finite ressources. Doesn’t sound sustainable to me.

qsdf38100··on In ‘The Book Against Death,’ Elias Canetti rants against mortality
Well we know that the physical brain is the support of mental abilities, because brain damage causes loss of abilities. It’s very reasonable to assume that you can’t be conscious without your brain.

Still mean living in a world of mostly very old people, and almost no children. Sounds depressing to me.
qsdf38100··on In ‘The Book Against Death,’ Elias Canetti rants against mortality
"Solving death" won’t help humanity. Isn’t that obvious to you??

For a starter, birth rates and death rates should be about the same otherwise it’s not sustainable. If you "solve death", birth rates will need to drop a lot.

Do you want to live in a world with almost no children? Just very old people all over the place. Sounds like a nightmare to me.

You need to let go, accept your mortality and leave some room for new humans to live. At some point you’ll have had your time, death is part of life.

Regardless of whether German energy policies were influenced by the Kremlin, they sure benefit the Kremlin an awful lot.

A problem for who? For X? For society? For Elon?
qsdf38100··on Launch HN: Airhart Aeronautics (YC S22) – A modern personal airplane
Note that one of Elon's goal with the whole hyperloop nonsense was precisely to divert investment from high-speed rail so that it wouldn't compete with "full self driving" cars.
qsdf38100··on Meta has run hundreds of ads for cocaine, opioids and other drugs
For me it was ads from a shady guy that was telling me that schools are how the "elites" make sure the masses don’t now the truth. Then he explained how his online reeducation courses would open a new world to me (and get rich).

I reported it and YT said the ad wasn’t violating any TOS. Meanwhile I was getting this exact ad like 20% of the time.

When corporations are complicit with the spread of conspiracy theories, we’re headed for a dystopian and fascist future.

qsdf38100··on French fiber optic cables cut in latest Olympics sabotage
Being weak vs Putin is what will start ww3. Same with Hitler, no amount of appeasing could have prevented ww2.

Not letting Hitler build up his military (which wasn’t allowed by ww1 peace treaties) and annexe foreign land is what could have prevented ww2.

qsdf38100··on Microsoft technical breakdown of CrowdStrike incident
> Yep. You just have to pretend that everyone who deployed Windows had an actual competitive choice available to them.

Could you elaborate? How is that related to security and availability being non negotiable?

qsdf38100··on Are people too flawed, ignorant, and tribal for open societies?
Are you saying the two parties are equally to blame? It seems to me that one party is trying to turn the US into a dictatorship while the other is trying to prevent that to happen, and failing.
qsdf38100··on Are people too flawed, ignorant, and tribal for open societies?
You seem to define right and wrong in terms of winners and loosers at the game of life. If you survive, you’re right? No matter what you do, the end justify the means? Is that what you’re saying?

I assume you were living in the US. How hard was it to adapt to the culture differences ? In what country are you living now ?
qsdf38100··on US and Germany foiled Russian plot to assassinate CEO of arms manufacturer
Yes, they are at war, they are all-in, while we are not. Maybe it’s time to consider we are at war too? How long are we going to let them wage information war, sabotage, political interference and corruption against us? They talk on state sponsored TV about nuking London, invading Europe, while we carefully consider whether Ukraine should be allowed to retaliate against Russian air bases that target civilians in purpose?

Not to mention they are about to get a Russian asset elected POTUS.

qsdf38100··on Compile-time JSON deserialization in C++
This reminds me of some coworkers I had that moaned anytime they saw 'template' in some code. They were convinced that templates were just bad, and that they should stay in the STL. Some of these people would then proceed to use void* and enums to perform the same computations (the C++ haters kind), or use virtual functions all over the place (the java-background kind). Not only was the result much more fragile (compile errors are now runtime errors), but it would also prevent inlining, not to mention the dynamic memory allocation fest.
qsdf38100··on Starcraft (A History in Two Acts)
I’ve recently started watching StarCraft games again. Lee young ho aka Flash aka the GOAT returned from the military, and it’s been fantastic to watch. Artosis is a great commenter as well.

There’s something really unique with this game, I feel no other RTS has the same depth. I plan on returning to this game when I retire, in 20 years. See you then.
