Any good advice for long-lasting brain fog after weed? I had a brownie on saturday and I still have a few problems with time and space, and short term memory. I've posted here about a similar issue, but that time, the overdose was much more severe and I had serious brain fog for a week straight. I must have had around half the dose this time, and it comes and goes. I started out this morning thinking it was over, though after watching some procedings on TV for a couple of hours, I started getting a bit foggy again. I'm drinking a ton of water, eating nutritious food, and trying my best, but it usually gets worse when I get to work. This is where it's the most problematic. Any and all advice taken.

I don't think it's fundamentally different from any other neurotransmitter depletion. Sleep, exercise, nutrition. Drink some coffee for a bit of a kick. I can't think of anything else that won't land you right back after it wears off. If there's a shortcut for when it's induced by weed specifically, I don't know it.

Indeed, time seems to be the only thing that helps. I still had the odd "space-out" today, six days later, so it's another week lost to this junk. It's not worth it at all, I'd rather just steer clear.

Is there any reason why Europe has so few skyscraper cities compared to Asia and North America? Or did it just happen to be that way?

I don't really know enough about European cities to say why they are different, but I can mention some of the factors that influenced development of skyscrapers in the U.S. First, there is geology. If ground's too soft, it's just not worth it. Manhattan is practically a solid rock. Bad for subways, great for skyscrapers. There are cities in U.S. where that skyscraper growth doesn't happen because ground is not suitable. Also, historically, cheap, high quality steel was huge. I don't think it's that much of a factor now, but it's part of why U.S. got into the skyscraper game early. And finally the way the markets work. Again, not quite as much of a factor now, but in the late 20th century people certainly tried to get offices closer to the trading floor, because the delay along the wire was making a difference in how efficiently you can trade. So in places like New York and Chicago that was a big part of why it made sense to build so close together.

Well for one large European cities have already been "established" so you couldn't really build a skyscraper in the city center. European houses in the center of cities were built to accommodate about 5-15 families or even more and if that wasn't enough then expanding the city wasn't an issue because there was plenty of space. A lot of European towns strictly regulate their image by introducing limits on how high a building can be and preventing modification or destruction of certain houses to preserve the historical look and charm. High rise buildings do exist in Europe but they are usually in the outer parts where new business districts are established.

Appreciate the answers guys, anyways I'm back with two questions haha

 

What is ray tracing in video games and why is it made to be such a game changer? (Could I ask to explain like I'm age ten or something since whatever I've tried to read on the subject leaves me confused lol) 

 

How did humans transition from communicating through grunts and random noises to having proper structured languages understood not just by a small elite group but by huge societies? Language in general is perhaps the most amazing thing to me

Start from there and make up your mind.

 

Some early ass human able to make up complex grunts probably dropped a mix tape and hence Proto-Indo-European was born.

Ray tracing isn't a new concept. What makes the nVidia RTX (and upcoming AMD equivalent) special is that it brings techniques that have been used, for example, by Pixar for making Toy Story 4 to your PC or console to work in real time.

 

The basic idea is very simple. Light ravels in straight lines (rays) unless it interacts with something. So to figure out what image an eye/camera would see, we work the problem backwards and trace all possible paths from eye/camera to light sources. Hence, ray tracing. In practice, to get a good image you have to either simulate an absurd number of rays or get clever about how you use the ones you have. Naturally, for real time rendering, we go with the later. And nobody really uses pure ray tracing for mainstream games right now. It's all about building a hybrid of traditional rendering with ray tracing.

 

Details get super technical very fast, so instead of getting into how, it's better to focus on what you get with it. There are three main categories of improvements that you get with ray tracing. (Yes, I'm generalizing a bit, but it'll do for keeping it simple.)

  1. Shadows. Without ray tracing, shadows come out pretty high contrast with sharp edges, and little or no coloration. With ray tracing, you can simulate shadows from real objects, like torch flame, a neon sign, or the sun in the sky, producing soft shadows with realistic color gradients. See Shadow of Tomb Raider RTX demos for some great examples.
  2. Global Illumination. If an object is in a shadow, it's not completely dark. You still get a lot of light scattered from other objects around. Without ray tracing, you either have that faked by artists or you do a lot of simulation in advance. Either way, the results can't change dynamically with changes in the scene. Ray tracing will help you get lights in the room just right as the door is opening from letting just a sliver of light in to fully open, lighting all but most distant corners. A good example is RTX demos for Metro Exodus.
  3. Reflections. Without ray tracing reflections tend to be pretty low quality and miss a lot of details. Ray tracing lets you get beautiful reflections off curved or even dynamic surfaces, like waves on the lake, even when the reflected objects aren't in the frame. There are some good examples of ray traced reflections in RTX demos for Battlefield V and Atomic Heart.

There are some other cool uses. PS5 should have a close enough integration of its audio and graphics hardware that it would let you use ray tracing for figuring how sound is reflected, producing very realistic audio in complex scenes. But I'm not aware of anyone taking this beyond tech demos. You also have a lot of opportunities for rendering sky, weather effects, and foliage (grass, leaves) using ray tracing, but I haven't seen any examples yet.

 

P.S. I should add, almost everything you can do with ray tracing you can do without and you can get very similar quality. The biggest advantage is that instead of spending a lot of developer time on faking realistic lights for particular situations, you instead just simulate realistic lights. This means that an indy game with good art team can produce something that's visually just as stunning as games by AAA companies with thousands of people working on them. So it really makes a bigger difference for developers, but the hope is, less effort spent on visual detail means more effort spent on making a better game.

Fascinating answers

 

@K^2 thanks for explaining it so well, even my dumb self understood for the most part haha. I don't mean to undermine ray tracing at all by asking this, just want to know for sure but it purely is a graphical thing right? Any similar concepts exist for other parts of gaming like regarding physics and simulating huge open words; do similar revolutionary concepts exist for those aspects too

 

Sorry if this sounds like a noob question, I don't have much knowledge in these things (or on a lot of things tbf lol) 

 

 

@paperbagdude fascinating article, will definitely read it in a more in depth manner once my sleepiness shakes off a bit. Its a shame experts don't consider it worthy for further studies, though I get that only assumptions can be made and acquiring solid evidence for these things is nigh impossible, but still it's quite a fascinating mystery

Ray tracing itself is pretty much just for pretty graphics and maybe some audio improvements. However, nVidia/AMD had to add a lot of nifty new hardware into the GPUs to make it happen, and that has uses beyond ray tracing.

 

First, there are tensor cores for machine learning. Part of the problem with ray tracing is that raw images you get are very, very noisy. The best approaches for fixing this involve artificial neural networks. (Example from animation of what raw ray tracer output looks like on the right vs de-noised image on the left.) To help with that, ray tracing GPUs have tensor cores designed to evaluate neural networks really fast. They aren't great for learning, from what I've read, but there are still all kinds of uses for this in gaming in theory. I haven't seen anyone push this yet, but it is an opportunity. Best uses would bein in animation and character behavior.

 

The other is volume hierarchies. This is even more technical, but the general idea is that if you have to see if things overlap in your scene by just trying every possible pair of objects it takes too long. So scenes suitable for ray tracing are organized into hierarchies that are much faster to search. Same kind of hierarchies are used, for example, in collision tests in physics engines. So in theory, there is a lot of FX and simulation code that can be done very cheaply on GPU with RT capabilities by utilizing these hierarchies. Again, I've never seen the hardware used this way.

 

Outside of these two key components, though, a ray tracing graphics card isn't that different from what we had before. It's just a piece of hardware designed to do A LOT of math in parallel. There are all kinds of uses for that in games and research, but we've been exploiting that potential pretty well already. It's not unusual at all for a game engine to include a compute pass in its graphics routine that uses GPU for general computations. The most common uses are for FX and cloth.

 

Unfortunately, most of the interesting things we care about in games have more to do with logic than algebra, and CPU is a lot better at that. So there isn't anything fundamentally new that ray tracing cards bring to the table. It's really just a quality upgrade.

I feel just liking your post isn't enough, I must also say I really appreciate you putting the effort to give an in depth yet clear explanation, admittedly some of this still goes over my head but it's got me a bit curious to do my own learning. Thanks

I would like to do that too but I'm too much of a wuss lol

 

Anyway I got a couple of questions

 

I find myself too addicted to my devices whether it be my mobile or PC and recently I'm finding it a bit hard to spend time without being hooked onto them. So I thought why not try some meditation and so I've been using my internet addiction to do random guided meditations on YouTube just to spend time without always viewing my device screens. The problem is I almost always fall asleep lol (not necessarily a bad thing but then I don't get sleep at night + I'd like to focus properly), that or I just start thinking of other things automatically/get restless to check the forums/other YouTube videos, that sort of thing. Any tips on how I can concentrate properly while meditating, or could it be that some people just aren't cut out for it? 

 

There's this classic question that goes- A train is about to run over five people tied on a track. You are in control of a lever that causes the train to switch tracks, but there is one person tied onto that track who will then get run over. Do you pull the lever or not? My question is how is this even a dilemma? Maybe I'm dumb but isn't the obvious choice to pull the lever and save more people? If the dilemma is you are causing the death of one person, not pulling the lever when you could would still mean you are responsible for the death of five, so is there something I'm missing here or is it not an obvious choice to make ie pull the lever?

@Secura that's one crazy video and a half. Thanks for sharing

 

Yeah, it's one thing to say from outside that it's a very simple decision to make, I didn't actually consider how it would be when put in such a situation. After seeing how the participants behaved, if I were in that place I don't know what I would do, I probably would have ran out of the room for help ignoring the command to remain inside so I can absolve myself of responsibility haha. 

 

Maybe another way to look at it is instead of 5 v 1 what if it was 5 v 3 or 4, would it be so easy to pull the lever then? But I kind of think the dilemma here is not what is the "better" choice to make, but rather whether one is bold enough to make a choice in the first place, if that makes sense

Do you put a full stop/period before or after an emoticon? 

Grammatically correct would be this, I think :dozing:.

But that looks awkward, I think. :sarcasm:

Anyway, I would prefer this variant (with correct use of capitals!) :p Or the second variant :inlove:

Is that what you ment? :monocle: (in this case I think you can't do it without a necessary q-mark)

The worst thing I can imagine is one endless sentence, full of emojis, without any capitals and without any puntuaction marks at all. You can read that, of course, but it takes longer to gather the information within the text 🥵

Additionally, I like to avoid the emos completely, I'm an old fart. Text is about information, not emotion. I try to separate this as best as I can, depending on the context, it's not always that easy. But I use them aswell, usually when it's simply funny.

Personally I put fullstops after the emoji like this sentence of yours-

Even I think this is grammatically correct 

 

But I've seen many use fullstops before the emoji like this-

Perhaps this second variant is the more clean looking one but then if you have to start a new sentence following the emoji it looks a bit awkward unless you put the sentence below and not after the previous sentence, if I am making sense. 

 

For sure, emojis kind of mess up the sentence structure for me at least in terms of punctuation, but I still like to use them haha so I was wondering what's the right way to put the fullstop. I guess you are saying to put the fullstop before the emoji?

You're confused? I'm sitting at home for four months now, my own coroni "information collecting/de-socialize process". But, it's comming close to jail, with this small appartment. *eyesrollemoji <<< another way, yay!

Yeah, beeing confused seems the normal process this year. Don't wonder! Namaste. If above comment made you laugh, that's half the prize. 😊

 

On the matter: No matter how you do it, in small (often funny) comments or 'punchlines', emojis seem totally appropriate and acceptable. In a personal discussion or debate (much more text) I think it's different. In a dissertation they're inacceptable.

I also never used an emoji, when writing an email to the boss like 'You're a piece of sh*t, I've alread done sixty hrs this week!' The circumstances affect the appearance and interpretation a lot. Psychology, like always. *stonedsmileey lol

Emojis/emoticons (delete as applicable) always go after a sentence. They punctuate a statement. Having a face before a period looks unnatural and wrong. Having a face afterwards makes sense, even if your choice of icon does not. 🗿

But what if you want to follow up that emoticon sentence with another sentence? :blink: Like this? Doesn't it look more awkward? Or is it still correct?

 

I guess when you use an emoticon you have to put the next sentence below and not after. :/

 

Like this perhaps?

That depends on whether emoji is part of a sentence or a sentence. For example, in the sentence, "I'm home, darling," there can be a substitution resulting in a complete sentence, "I'm home, 💗." In this case, the heart emoji is a vocative expression and is delimited by commas, same way the word "darling" was in the first example. And because it is a part of the sentence, a full stop follows. In contrast, "I'm home. 💗" is also grammatically valid. Here, the heart emoji is a standalone expression of a thought and may be considered a separate sentence. A sentence consisting only of emojis would not, usually, end in a full stop. Or, in this case, since it's being quoted, the punctuation omitted is a comma.

 

Also, I'm making this all up as I go, but I hope it sounds convincing.
