I Can't Show You How Pink This Pink Is

vil says...

It does not have to be about fitting into gamut, pink is a combination of blue and red light, which monitors are good at.

The problem with real world materials is that perception is not as simple as that. The combination of reflected, refracted, and even radiated (transformed wavelength) and polarized light, the micro-structure of the surface and possibly other properties can influence perception.

Like your favourite washing powder makes your whites whiter, this stuff makes pinks look pinker somehow. Its about fooling your eyes in specific conditions. You can simulate the difference between a known pink - a standard colour sample - and this awesome new pink by putting them side by side and calibrating the camera and monitor to show the new pink as pink and the reference pink as less pink, like at the end of the video, but that cant beat walking into an art gallery and seeing it with your own eyes. I mean probably, I havent seen this particular pink, but I have seen modern paintings which look nothing like their RGB or CMYK reproductions.

Games that think more gameplay mechanics equals more fun

shagen454 says...

Agree. Can't stand all the superfluous fetch quests - at this point I'm even sick of inventory management. In games like Fallout, or Elder Scrolls, Witcher - these days I hardly even loot the corpses because I'm so sick of it after 25+ years.

One of the best games I've played recently was - What Remains of Edith Finch - a linear, "walking simulator" which implements innovative/interesting design solutions to drive the story forward, very detailed and very tightly designed - kind of on the opposite spectrum of open-world RPGs - but very awesome.

Climate Change: What Do Scientists Say?

newtboy says...

What do real scientists say?
...the one's he worked with all said Lindzen is totally wrong, and his views are not held by the vast, VAST majority of other scientists that actually work in climatology. He's a political shill now, working for 'conservative think tanks' to deny climate change.

https://insideclimatenews.org/news/06032017/climate-change-denial-scientists-richard-lindzen-mit-donald-trump

Note, his graph at the beginning that appears to show no significant rise because as usual they start in late 97-98, a super hot El Nino year (the hottest on record) typically used as a starting point to pretend that temperatures aren't rising as fast as they are. Start at any other time to see how different the results are. This graph contains the hottest 15 years in recorded history over a period of the last 19 years. That's pretty telling by itself.

1)the climate is always changing-but according to natural cycles, we should be in a cooling period, not a warming period.
2)so at least in his mind, everyone agrees CO2 is a greenhouse gas that causes warming...that's better than most deniers.
3)"little ice age"-During the period 1645–1715, in the middle of the Little Ice Age, there was a period of low solar activity known as the Maunder Minimum. The Spörer Minimum has also been identified with a significant cooling period between 1460 and 1550 (it was not caused by low CO2 levels), and CO2 is produced more in warmer temperatures than cold, so starting shortly after then you can claim the CO2 levels have been rising since well before the industrial revolution...which cherry picked like that may be technically true but is again misleading by starting at an unusually low level following a low level solar period, but the level of that rise has consistently risen since the industrial revolution, and is incredibly higher than any natural mass releases besides rare massive super volcano eruptions that caused mass extinction events.
4) just plain not true, and not agreed on by scientists.
5)What they actually said-
Improve methods to quantify uncertainties of climate projections and scenarios, including development and exploration of long-term ensemble simulations using complex models. The climate system is a coupled non-linear chaotic system, and therefore the long-term prediction of future climate states is not possible. Rather the focus must be upon the prediction of the probability distribution of the system�s future possible states by the generation of ensembles of model solutions. Addressing adequately the statistical nature of climate is computationally intensive and requires the application of new methods of model diagnosis, but such statistical information is essential.

Confident prediction of future weather is not possible, weather predictions are based on statistical probabilities too. Because they aren't perfect doesn't mean they're wrong, useless, or should be ignored until they're 100% right every time. More funding for more study will improve the predictions consistently, but we are intentionally defunding them instead.

Religion channel? As in the religion of climate change denial? That's not what that channel is.
Philosophy channel? What?
Learn channel, only if the viewer looks into his BS elsewhere to learn the truth.
Lies, yep...controversy, yep....politics, yep....conspiracy,OK. His ilk are steeped in those, but you left out money, the driving force for all the deniers controversial, political lies and crazy conspiracy theories. ;-)

Star Trek: Discovery - First Look Trailer

THE DARK TOWER - Official Trailer

moonsammy says...

I don't know that Carlin's voice would be the right one, but doing so wouldn't necessarily be an issue for the character of Blaine. Seems reasonable to have a computer simulation of a particular voice rather than a voice actor specifically acting out each line. I'd argue however that if we're going to resurrect someone to voice Blaine, let's go with Alan Rickman. Just the right blend of civilized / polite and deadly serious / menacing.

Edit:
I've been a fan of the books from sometime between 3 and 4, and love most of the story. The last three books lost me some, as they felt quite different in tone. Even Wizard and Glass felt a bit of a miss, though it was a solid story in its own right. I frequently avoid watching trailers for films I know I'll see, so as to avoid spoilers and being mislead if the trailer happened to be poorly made. I plan to see this movie, and originally came here for the comments exclusively; having read them, I chose to watch it. I get the impression that the actors treat the characters well, and they feel like good interpretations. McConaughey's Walter is hard to read with what little we see here, but I've generally liked him in other things.

My biggest worry is that visuals all seem too clean, and the more sci-fi direction bothers me some. To me Mid-World always seemed like a character itself. An ancient thing, being stretched thin, fighting to hold itself together and losing. High tech doesn't feel right there, like the extreme entropy would have rendered it all non-operative. There was some tech here and there in the books, but most of it was broken or breaking down.

00Scud00 said:

Blaine is a pain. But if we resurrect George Carlin to voice act him that could be fun.
I'm cautiously optimistic about this, they've clearly taken liberties, but then most of what I have seen could still fit into the lore of the books.

Neuroscientist Explains 1 Concept in 5 Levels of Difficulty

dannym3141 says...

Great video, great explanation technique.

If we created a brain from a map (even a perfect one), put it in an android and set it going, how would we know that it would behave the same way as the person who was mapped? I'm not sure there is a way to really know. Is it alive when it's good enough to trick someone? Is it alive when it's smart enough to turn to you and say, "If you switch me off, will i die?" Is it fair to "kill" that one but not the ever-so-slightly less advanced one who didn't ask the same question?!

Let's say we create a simulation of someone's brain and run a particular scenario by it. Could we predict possible outcomes and their probabilities? That's kinda close to minority report. If our justice system is right 95% of the time but the brain simulation was right 98% of the time, less people would be wrongfully judged so we should act on thought-crime.

Neuroscientist Explains 1 Concept in 5 Levels of Difficulty

dubious says...

I'm a bit surprised the grad student or expert didn't discuss neuromodulators more. The fact is we already have the full connectome of a much simpler system, a worm (C Elegans). And this full mapping is considered insufficient to fully understand the simplified worm behavior because it doesn't fully capture the diversity of different neuromodulators and how they effect processing in neurons. It matters if the neuron is releasing dopamine, serotonin, glutamate, etc. There are ways to approximate these from EM images by analyzing the synapse properties, but ultimately it leads to a much larger problem in understanding neural processing.

In a similar light, the connectome project does not do a good job capturing synaptic strength. We don't really know just from the electron microscopy how strong the connections are. We can try and approximate it by looking at the size/formation of the synapse but ultimately this falls short.

For instance, my memory is that thalamocortical projections (thalamic nuclei to L4 of the cortex) do not make up the primary inputs to L4 on a structural connectivity level, but the strength of those connections are much stronger then the more numerous cortico cortical connections. I don't think the connectome from EM images will be able to pull that out.

The connectome is important, the same way knowing the human genome is important. However, it's really not going to tell us how to simulate a person. It's an important step to be sure, one we are still a good ways away from finishing last I checked (which was three years ago ...)

Women Drivers in GTA V

MilkmanDan says...

No "apology" necessary -- I can definitely see how it would look like bad AI in a one-off context like this, I just wasn't sure if you were making a sarcastic dig at them or not (and it would be fine if you were, also).

There's actually an amazing level of depth in subtle details that get put into the GTA games. Some of them are immersion-enhancing things that you tend to only notice on a subconscious level, like "tick tick tick" sounds of car engines cooling after you shut them down. And some are little in-joke tropes like this.

Honestly, it seems like it would take a LOT of work to coordinate all of those details and references and keep them fairly internally consistent. On top of that effort, the payoff is arguably somewhat dubious in cost-benefit terms -- a few people with notice these things and find them a little bit funny, a few will notice them and be offended to varying degrees, and a bunch either won't notice at all or will chalk them up to AI / simulation glitches.

But I still think it is cool that Rockstar doesn't shy away from including this kind of stuff, and/or stuff that more blatantly pushes the limits.

Apologies. I have never played the GTA series games for very long. It just looked like bad AI and it was weird to go with the old trope of "women drivers".

Ghost In The Shell - Trailer #2

RedSky says...

I'm more relating it to the Stand Alone Complex series, particularly the second season which is what the adaptation seems to be based on from the trailers.

It is clearly impossible for them to cram the content of that 26 episode series into a movie and I'm frankly not sure why they decided to adapt it rather than the original movie.

That had plenty of discussion about simulations, emergent phenomena and group think. Definitely bordered on pretentiousness (there was an episode which adapted Taxi Driver) but still very enjoyable.

entr0py said:

My memory of the original movie is that it was that there was about 5 minutes of the characters philosophizing on the difficulty of self-identity in a cyber world amid an hour and a half of sexy sci-fi robot murder sprees. I think they can match that.

Ricky Gervais And Colbert Go Head-To-Head On Religion

dannym3141 says...

I think there are aspects of this that fall into the realm of philosophy.

I personally don't think we can ever have "The Truth" in that ultimate sense. Pretend for a minute that the SUVAT equations (the equations of motion) are completely accurate. I can drop a ball from a certain height and you can time it and we'll find to some degree of accuracy that the equations were right.

The ball and the floor didn't need to calculate anything. Whilst me and you sit there with a stopwatch technical manual, assorted tape measures to find the distance, expensive cameras to figure out when i dropped the ball..... Whilst we are tying down an uncertainty, the ball and floor have already done it.

When you get right down to it, we simply cannot know an exact time. We can never know an 'exact' anything, because now we need to discuss where the "ball" ends and where the "floor" begins on a molecular level. And no matter how much we agree, the uncertainty principle gets us in the end - we don't and can't know the exact location of fundamental particles. An "exact" anything ends up being a conceptual thing that we can't ever test.

But where i'm going with this is that we're kind of talking about the nature of understanding. We know the volume of a sphere if we know its radius, but how do we create the same sphere accurately? Our brains don't have a resolution, but the tools we use in reality do - reality itself quite possibly has a resolution. We think of minecraft as a blocky, low resolution simulation of an analogue reality. Similarly, i think maths is an 'analogue' (in that it can be "exact") simulation of a limited resolution reality - reality only looks analogue when you don't look very closely.

All that is to say, we DO understand the ball dropping and hitting the floor, but "exactness" is a thing that only exists in the act itself. The only thing left for us to decide is what we consider accurate enough.

Perhaps "god" wanted to know what would happen if he set off a big bang. He sat down, calculated it all out in the language of the gods (the language of perfection; maths) and realised that due to uncertainty, the only way to know exactly what would happen was for it to actually happen. (Douglas Adams?)

It doesn't make a difference to your ability to make a statement per se, but speaking to a friend of mine who is a physicist his answers are somewhat different. He's suggested that reading more about it will make it more confusing and that we are invariably wrong and don't know shit. I happen to agree with him. That's not to say one shouldn't attempt to gain as much knowledge as possible, but that it's not always as easy as "go read a text book and it should be nice and clear", because reading it should hopefully generate more questions than it answers. Hopefully I've worded that so it makes sense.

Anyway, the sum of human knowledge is dynamic steaming pile of shit. Yes, it's gotten us a long way. But we're still like dung beetles tending to it and it will be a long time until we can transform it into something close to the truth.

Maybe when we can integrate AIs into us we'll accelerate things a little.

King David

Mordhaus says...

Funny, but flawed it's own way.

Let me preface this commentary by saying I am not in any organized religion. I go back and forth in believing in God and also not being able to find proof he exists, basically an agnostic theist. So this is not in any way an attempt to 'prove' anything other than that I disagree with the way the video is portraying the biblical tale. I also know there are far more egregious examples than this story of God as an uncaring, flawed being with an uncertain temperament.

First, this story is one of the 'go to' stories that most atheists or anti-religion people look to for a clear example of the 'wrongness' of the bible or God. The reason is, if you don't take anything else into context, this story is massively damning! What god would call for a mass genocide out of the blue, right? Certainly not one people consider to be good!

But, if we look at the context of the bible in the Old Testament, we see that this is not wholly out of line for the character shown of God. If we take the statements of the bible as literal, then God has already shown he will destroy any threat to those he considers his 'chosen people'; even those who are/were part of that group.

In this case, the Amalekites were descendants of Esau. Esau was the brother of Jacob (later named Israel) and was supposed to inherit the blessing of his father, as well as command over the 'chosen people' of God. Esau was of rough nature and was a hunter. Once he was starving and went to Jacob, who tended the fields (sort of the Cain and Abel bit all over again), begging him for a bowl of lentil soup. Jacob told him that he would give him the bowl if Esau would pass his birthright (blessing and command) over to Jacob, since obviously Jacob was more able to care for his people than a solitary hunter. Esau agreed, but never really meant it, he was just hungry and was willing to say whatever he needed to so as to get that soup.

Jacob was dead serious though, so he took the birthright and became Israel, the leader of God's chosen. Esau was livid and swore to murder Jacob, who fled. Esau never got the birthright back, but he did sire the people who became the Amalekites, who in turn swore vengeance on Israel-ites.

This becomes important as time goes on, because basically every single time the groups encountered one another, the Israelites tried to be peaceful but the Amalekites always attacked.

By the time Saul was king, God chose to have him go and destroy the Amalekites, deeming them beyond saving. As he had told Moses during the first Amalekite attacks, he had Samuel tell Saul to blot their memory from history, wiping them out completely. Saul chose not to do this, sparing their king and some animals. Because of this, God replaced Saul with David.

So, now we come to the main part of the discussion. Like I said, this story is used quite often to show the capricious nature of God. However, like I said, it uses the story out of context. Now that we have the 'historical' description of the origin and ongoing nature of the conflict, we can put it into context.

If you are going to dissect the nature of 'God' as shown in the Old Testament, you have to look at the information given to show that nature. The bible says he is all-knowing, but it also says that he gave mankind free will. If you look on God as more of a creature running a simulation, he hopes that humanity will come to follow his rules of their own accord, even though he knows many will not. He chooses Israel and his descendants to be his 'messengers' to the other people that have chosen not to follow his rules, basically they are his missionaries that he hopes will lead his simulation to the proper conclusion.

Any group or race that tries to eradicate his messengers is a threat to his simulation, so he eventually will deal with them harshly. Sodom and Gomorrah, The Great Flood, and other examples of God deciding that he needs to protect his 'messengers' and clear off the playing board. In the case of the Amalekites, by this time period mentioned in the story, we are talking about generations of them trying to destroy the Israelites. So, God tells Samuel to tell Saul that they must be wiped from the playing board. Saul exercises his free will, therefore David enters the picture.

If you look at free will and God's choice of his messengers, as well as his protection of them, you get this story situation. By telling Saul to wipe them out, God is saying that he has tried to look the other way, but the Amalekites will never stop as long as they exist. Therefore they must be dealt with in a manner that will prevent them from rising as a people in the future and attempting harm to his messengers again.

It still doesn't paint God in a perfect light, but makes him more of a tinkerer. He keeps creating flawed inventions that choose to follow their own path and not his. The sad thing is, if you assume that he is all knowing, he knows this is going to be the end result. He creates angels and they turn on him. He creates humans and they turn on him. Then he creates Jesus, a combination of god and human, who doesn't turn on him. It is almost like he decides to create a Hero unit that can show the other simulations an easier path to winning.

Realistically and analytically, I know it doesn't make perfect sense. That is why I have my struggles with wanting to believe and then not being able to logically. If you choose to look at God as being a flawed creature (again, assuming that you believe he exists), the whole thing sort of makes more sense. In any case, we all have our own opinions and beliefs. I hope that my wordy post has explained how I try to work through mine.

"The Political News Media Lost Its Mind"

Published on Apr 14, 2016

The aerobatics skills of Russian pilots over the US destroyer Donald Cook in the Baltic Sea left the Pentagon and other US official running for cover in Washington over “aggressive close interactions” with Russian fighters jets.
Trends
Russia-NATO relations
Releasing the footage of Russian jet flybys in the vicinity of the destroyer, the US Navy said that its vessel has encountered multiple “aggressive flight maneuvers ...within close proximity of the ship,” some as close as 30 feet (10 meters) on Monday and Tuesday.

The set of incidents took place as the US ship, which had sailed from the Polish port of Gdynia, was conducting exercises with its NATO ally Poland in the Baltic Sea. The Navy announced that the SU-24 first flew over Donald Cook on Monday as US sailors were rehearsing “deck landing drills with an allied [Polish] military helicopter”. The numerous close-range, low altitude encounters were witnessed at 3:00pm local time, forcing the commander of the ship to suspend helicopter refueling on the deck until the Russian jets departed the area.

The next day, the Navy said, Russia caused concern among US sailors when a Russian KA-27 Helix helicopter flew seven times over the ship at low altitude in international waters at around 5:00pm. Some 40 minutes later, two Russian SU-24 jets allegedly made a further 11 “close-range and low altitude passes”.

“The Russian aircraft flew in a simulated attack profile and failed to respond to repeated safety advisories in both English and Russian. USS Donald Cook’s commanding officer deemed several of these maneuvers as unsafe and unprofessional,” the Navy said.

Judging by the videos released by the US Navy, the sailors were nonplussed by the Russian aerobatic skills. They gathered on the top deck of the destroyer to watch the Russian pilots.

“He is on the deck below the bridge lane...It looks like he’ll be coming in across the flight deck, coming in low, bridge wing level...Over the bow, right turn, over the bow...” the voiceover on the footage states in what looks more like an instructor’s advice on how to maneuver in open waters, rather than the panic that the central command presented it to be. At least on the video no one can be seen running for cover.

According to a US defense official who spoke with Defense News, sailors aboard the Donald Cook claimed that the Russian jets’ low altitude stirred waters and created wake underneath the ship. US personnel on the American vessels, also claimed that Su-24 was “wings clean,” meaning no armaments were present on the Russian jets that could have posed a threat to US operations in the Baltic.

Yet at the same time, the official noted, that this week's incidents are “more aggressive than anything we’ve seen in some time,” as the SU-24 appeared to be flying in a “simulated attack profile.”

The Russian overflights have caused panic over in Washington, with White House spokesman Josh Earnest calling the actions of the Russian pilots “provocative” and “inconsistent with professional norms of militaries.”

“I hear the Russians are up to their old tricks again in the EUCOM [US European Command] AOR [area of responsibility],” Operation Inherent Resolve spokesman Col. Steve Warren said during a briefing on Wednesday, adding that the US is “concerned with this behavior.”

“We have deep concerns about the unsafe and unprofessional Russian flight maneuvers. These actions have the potential to unnecessarily escalate tensions between countries, and could result in a miscalculation or accident that could cause serious injury or death,” the US European Command said in a statement.

In the meantime Adm. John Richardson, the chief of naval operations, thanked the US crew for keeping their cool during the stressful situation.

“Bravo Zulu to the crew of USS Donald Cook for their initiative and toughness in how they handled themselves during this incident,” the admiral said on Facebook.

Russia has yet to comment on the incidents but most likely the Russian air craft flew from the Kaliningrad region, bordering Poland. Kaliningrad is the headquarters of the Russian Baltic Fleet, which also includes the Chernyakhovsk, Donskoye, and Kaliningrad Chkalovsk air bases.

Ultra Spiritual Life - Flat Earth Theory

ForgedReality says...

I'm not joking. I've gotten into heated debates on multiple occasions with people on Google+ who honestly believe there is no way the Earth is not flat. At first, I couldn't believe they weren't fucking with me, but they were SERIOUS. Terrifyingly so.

You go and look at their other posts, and there are whole communities filled with certifiably crazy people talking about some seriously demented theories. NASA photos from ISS are simulated; the round earth theory is a sophisticated psy-op meant to enslave our minds; the entire universe is flat, rotates around the Earth, and gravity is somehow a lie, and every photo and video showing a round Earth is a fake.

These people are breeding, dude. In 2016. I'm terrified.

Ask them how a sundial works. It's one of those things that's simple to think about or even draw. Get them to tell you how the sun rises and sets, and then ask about sundials - and why do 2 sundials separated by a significant distance read how they do.

If you make them 1000 ft tall sundials, you can use the horizon line of sight argument on them too.
