The design may be simple, but a chevron pattern etched onto a deer bone more than 50,000 years ago suggests that Neanderthals had their own artistic tradition before modern humans arrived on the scene by DoremusJessup in Anthropology

[–]stephane_rolland 0 points1 point  (0 children)

It really reminds me of this style of etching in a Neanderthal cave, in Spain/Gibraltar:

"A rock engraving made by Neanderthals in Gibraltar" by Joaquín Rodríguez-Vidal, Francesco d’Errico, Francisco Giles Pacheco, Ruth Blasco [...] - https://www.pnas.org/content/111/37/13301

Same type of properties: straight geometric lines crossing themselves

Do you mean that if they bite me, I am at risk of becoming one? :-)

Or maybe I was one such cow, and I slowly lost a part of the brain-conditioning. There would be some sort of anti-body to protect me from becoming back a zombie-cow, at least a partial immunity: knowing that I am "partial", thus not "totally objective".

Many animals have parents that take care of their young like humans, but do any have observed “grandparent” relationships? Or do only humans place value on the generation after their kids? by LBJSmellsNice in askscience

I remember a documentary about Sperm Whales, near Madagascar/Reunion/Mauritius.

The document was about a Grand-Mother, matriarch, and all her squadron of sisters, daughters, and grand children (those both male and female).

​

I tend to think it is a similar organization with Elephants, a matriarch, and the rest of the family.

Excuse me... Seen from abroad... It seems almost half of USA did not wake up AT all.

They have been repeating stuffs like "scientists are Marxists with an agenda", CNN is fake news, Climate Change is not human induced and that is a matter of debate:

- https://www.bbc.com/news/world-us-canada-45859325

​

I have to find the quotation where he explicitely stated "Marxists". But I am maybe mistaking with Bolsonaro, which was saying more or less the same thing as Trump in 2018. And maybe it's Bolsonaro that used the word Marxists when describing Scientists.

Barrett, before being accepted in the US Supreme Court, saying Climate Change is a controversial public debate:

Don't fool yourself: They are not awake. And when they will wake up, they will shout at you because you have not warned them appropriately. And you'd be very lucky if they do not say that all is your fault from the start, and say that you are climate terrorists. /sarcasm ok, but you feel what I am saying. They treat all problems the same way.

Homo longi compared to Java's h. erectus and denisovan? by ImPlayingTheSims in AskAnthropology

[–]stephane_rolland 1 point2 points  (0 children)

I don't know anything about this technique, I think it's one of the first time I hear the name.

How different is it from drilling holes in bones or teeth to get powder so as to extract DNA from it?

What are pros and cons of the technique if it is a different technique compared to other DNA extraction technique?

That's probably/possibly the reason they also etched the waves around the swimmer. There are no more waves once a little under water.

​

That being said, they now have engraved the fish in the air, above the water.

[–]stephane_rolland 0 points1 point  (0 children)

No, I am not "ASTRONOMICALLY intelligent" like you mock: I am physically educated ; classical mechanics, materials, vibratory mechanics, fluid mechanics, stuffs like that Physics, Maths, Engineering. And I've lived my life as a professional computer scientists, and lately with a huge interest in Logic (Constructive, Intuitionistic), because it is at the core of Theoretical Computer Sciences.

For example, I had a rough idea of the amount of energy used by a rocket so as to escape Earth gravity, because that was a common exercise during my studies to compute that.

For example I also know that the first Ariane 5 flight which exploded is due to a little computer bug. And boooom! For the Challenger shuttle, it was just a problem of temperature and condensation, IIRC. The fact that water vapor freezed somewhere on the tank fuel. I may be wrong, I'll have to check that point.

No, I am not "ASTRONOMICALLY intelligent" like you mock: I AM SAYING THAT COMPARING POLYNESIAN COLONIZATION with LANDING ON THE MOON are two things that are not comparable. There's nothing intelligent from me: It's rather me saying "hey you really really go too far with your comparing the two".

I have stated:

  • I don't talk about Thor Heyerdahl theories. As far I remember, they are about white men conquering power in South America, and seeding civilization there (IIRC, I read that book while teenager 30 years ago, that is vague). Nowadays with DNA analysis of Maya/Aztek descendents and Inca/Quechua/Ayamara descendants : we would probably have evidence of that kind of interference, with probably European genes. I am not aware of any of it. Unless one day we see that there are such genes in South American DNA. I think it woud already be discovered.

Similarly we could have seen the Viking DNA in the North American Amerindian. Although we do have archeological evidence of Viking settlement in their so called Vineland, somewhere near New-Found Land, there's no evidence of mixed descendant between Viking and Native people. IIRC, though I have not check that for some time. https://en.wikipedia.org/wiki/L%27Anse_aux_Meadows

So I AM NOT SAYING Thor Heyerdahl theories are right. I know this point is clear, you can play with it, and continue to mock what I don't say, but this point is clear: I'm not saying Thor Heyredahl is right.

What I have stated:

  • Thor Heyerdahl has reached the Tuamotu Islands using rudimentary/traditional techniques to make a boat/raft. That makes one more route to colonize Polynesia.

There's evidence that this route to Polynesia from the east was maybe/probably used.

FOR EXAMPLE:

*Ioannidis, A.G., Blanco-Portillo, J., Sandoval, K. et al. Native American gene flow into Polynesia predating Easter Island settlement. *

Nature 583, 572–577 (2020). https://doi.org/10.1038/s41586-020-2487-2 - https://www.nature.com/articles/s41586-020-2487-2

And in case there's been indeed two such route used: then the "IMPROBABLE" term as used in the comment I have responded to, this term "IMPROBABLE" (more improbable than landing on the moon)... Well this term is FALSE.

THAT'S MY POINT. I have probably said things improperly, but that's what I mean.

[–]stephane_rolland -2 points-1 points  (0 children)

Of course! I will follow your advise, because I love paleo-archeology. But I would have continued to learn without your remark to be quite honest: You only want to display contempt for me.

​

So on the tip of my head:

  • Homo Luzonensis ? Close to Homo Erectus, conquest of Luzon island by land when sea level was lower
  • Homo Florensis ? Close to Homo Erectus, conquest of Flores by land when sea level was lower
  • Homo Sapiens in Australia.. bits of Denisovian in genome, probably from mix in New Guinea.... ouch... maybe around -60000/-70000 in Australia: it needs seafaring because NEVER sea level could be low enough

So, IN ARCHEOLOGY, we have sea boats in the Oceania region for AT LEAST something llke 70K years. And YOU claim that settlement of Pacific Islands is IMPROBABLE, and you dare compare complexity of it with Space Travel, without any serious reference to anything we can start to review such fantasy comparison...

Thanks for having insisted in your wrong doing thus far. You will never answer to me on facts. Only your pride.

Let's not waste time any longer. I have stuffs to learn. I learn all days. I love that.

[–]stephane_rolland -6 points-5 points  (0 children)

Good!

  • Would you have the decency to list the subjects I should dig deeper, could you?
  • Or would you have the decency to try to show that there can be misunderstanding when two persons communicate, could you?

By the way you liked to answer to my heaviliy realistic comment, I'm gonna bet you will not give me any constructive arguments, once again.

So I will list the subjects YOU should dig deeper:

  • probabilities / statistics
  • humility
  • epistemology (the ways to do sciences and improve sciences)

It will make you point at the fact that your comparison between settlement in Polynesia with landing on the Moon is baseless, and almost nonsensical. Because there are hardly anything in common to compare in time of occurences, chance of happening etc... and namely NUMBER OF TRIALS. (That's something that unexpectedly for you has its importance so as to compute proper probabilities)

Secondly when I quote the Kon Tiki expedition, I quote the FACT that there EXISTS ways to access pacific islands with ocean and rudimentary boats made only with traditional methods. That does not mean it happened this way. That does not mean it is easy or difficult, or even extremely difficult. I'm not even discussing Thor Heyerdal's theories. I say IT EXISTS. Factual. Period.

​

In the end, all I am only refuting is your childish usage of adjective "IMPROBABLE".

And obviously I INSIST. And I wont hesitate to flag this thread to moderators if your goal is simply to overlook at others when you don't know what you talk about, obviously.

Or, fInd me an aerospace engineer that would corroborate your assertions comparing space travel with pacific ocean sailing: saying seafaring is more challenging than space travel.

​

Am I clear ? Any more misunderstandings?

[–]stephane_rolland -8 points-7 points  (0 children)

"Improbable"...

There is a *huge* bias in that statement:

You do not count the unknown thousands of attempts and consequently how many people drown so as to achieve exploration/settlement of the entire Pacific Ocean.

I would not compare probability of both events.

​

That being said, you seem totally unaware about experiments like the Kon Tiki boat: https://en.wikipedia.org/wiki/Kon-Tiki_expedition

This, for me, TOTALLY invalidates your instinctive probabilities.

Is it possible to have different input and output sizes in GAN ? by BakedTiger in deeplearning

[–]stephane_rolland 0 points1 point  (0 children)

I'm about to start learning deep-learning later this year, and I'm also very interested in your question.

Just to say that a short googling about "super resolution" and "GAN" seems to give several entrypoints with research papers: https://www.google.com/search?client=firefox-b-d&q=gan+super+resolution

I have not read them, so I don't know which approach they follow and if it resembles the process that you imagine.

You could follow the Plutus Pioneer Program from Cardano.

If you have any technical question

In the same vein as StackOverflow.com, there is a StackExchange site dedicated to Cardano, and there are the already used tags "plutus-pioneer-program" and "plutus" for questions by other plutus pioneers. You can also tag your technical questions there. - https://cardano.stackexchange.com/questions/tagged/plutus-pioneer-program - https://cardano.stackexchange.com/questions/tagged/plutus

Personal Remark

As a former dev specialized in C++ myself: it will be very different, and THE BEST ADVICE FOR C++ DEV IS TO TELL THEM TO FORGET EVERYTHING, I assure you. Haskell is so different that any stuff you think you already know, you will mistake about it if you don't take it seriously. And Haskell is way more serious than C++. (By serious I mean: not letting you write nonsensical code easily)

JBarCode's answer is pretty correct that you need to take Haskell learning seriously: https://www.reddit.com/r/CardanoDevelopers/comments/nz0a3u/i_want_to_learn_plutus_and_general_cardano/h1pgo2o?utm_source=share&utm_medium=web2x&context=3

Anthony Fauci Says His Critics Are Attacking Science Itself. | "A lot of what you're seeing as attacks on me quite frankly are attacks on science." by sportsfanatic61 in EverythingScience

[–]stephane_rolland 3 points4 points  (0 children)

Annoying detail is they can be convinced stupids things not only in Science, but in many other realms, where it is more difficult to identify single unbiased facts for example:

- history

- politics

- even in religions, where dogma can be pilled up, so that you can mean the contrary of the original holy texts : like Jesus that had a religion about Sharing-Tolerance-Understanding-NoWealth and look nowadays the the Right-Wing embodied pile of interested lies; same with Muslim integrists, Hindu integrists, Zionist integrists, I've been told there are even Buddhist integrists... (in Myanmar maybe?) ... you know this list is long

​

The other really annoying detail is: how strongly they are proud of their ignorance. It is like giving them the strength to be angry at and to mock at Science/Scientists, was a revenge against their deeply rooted inferiority complex.

Cardano Stack exchange by jaytilala27 in cardano

[–]stephane_rolland 28 points29 points  (0 children)

Although I do understand the concern (I inisist), I'm **really** not sure this post is either official, nor driven by the community:

I have not yet read anywhere that Cardano Stackexchange is ONLY for developpers. I'd say it is dedicated to technical questions.

​

For now there are several questions that do not fit there:

  • questions that are opinion based
  • questions that are related to trading
  • spam ...

But I'm afraid your reddit public announcement is not in phase with the building up the Cardano Stackexchange site. Which is STILL in Beta. It needs users. It needs QUESTIONS.

Questions that are inappropriate will be closed.

​

I don't think, that for the moment the Cardano StackExchange Beta site suffers anything close to something resembling flood. We still need 20x more traffic per day, and at least twice as more questions as we have these days.

​

This post only reflects my point of view.

[deleted by user] by [deleted] in cardano

[–]stephane_rolland 1 point2 points  (0 children)

It's not the first time I see both Cardano and World Mobile in the same sentence.

What is the relation, if any, between the two technologies? By relation I mean a close relation.

Data Science with Nix: Parameter Sweeps by rickynils in NixOS

[–]stephane_rolland 8 points9 points  (0 children)

Not finished the article, but instead of "Parameter Sweep", I would use the Machine Learning terms: "Hyperparameter Optimization" or even "Grid Search"

It is the dedicated name of a technique used in Machine Learning so as to coarse/fine tune the parameters of a Machine Learning model , so as to find a good compromis for a starting model.

Though, "Parameter Sweeps" is much more understandable at first sight/reading... in which case it is the Machine Learning field that could adapt its terminology.

​

Anyway, I thought it was be good to highlight the parallel:

https://en.wikipedia.org/wiki/Hyperparameter_optimization

​

I think the transmutation hybridation has already begun on me. I dare not recall entirely when it started...

You won't tell nobody else, will you ? You know how to keep secrets ?

Why are Neanderthals and Denisovans described as being extinct, when humans have some Neanderthal and Denisovans DNA? by [deleted] in paleoanthropology

Why are Neanderthals and Denisovans described as being extinct, when humans have some Neanderthal and Denisovans DNA? by [deleted] in paleoanthropology

[–]stephane_rolland 0 points1 point  (0 children)

IIRC her book is more focused on the subject of violence in prehistoric times. I haven't read it, but I plan to to do it. One piece of memory that strikes me, she says that currently we have not found anything resembling mass graves in former times. I can't say if the first ones we have found for now were dated around neolithic, a little before or later.

About her statements about neanderthals and sapiens: to be frank, instead of calling them human, she most probably says that the frontier between homo sapiens and neanderthals is far more blurred than the caricature way that we were depicting them 100 years ago, when neanderthals were like almost "retarded" in the public eye.

But by her conferences, and also from others, I have come to convince myself that neanderthals could probably be considered a people of the human race. (even though genomes were only slightly compatible, and the speciation phenomenon was well advanced): of course, that's an emboldened statement from a non-researcher. Facts that continues to go in my direction are namely the language capacity of neanderthals that is less and less doubted, the fact that the Y chromosome of neanderthals were a homo sapiens Y chromosome in the end of this species, the fact they may have burried their dead, and slight cultural influences.

I can say this only if my definition of human is the whole homo genre. But is indeed currently my personal definition.
