I know a couple reasons to mill pavement. It’s done to obliterate old markings or prepare a weathered surface so paint will adhere strongly to it. Neither of those seem applicable here. Cichlidae in the traffic engineering thread would know.

Pavement markings placed on fresh asphalt tend to soak up oil from the bitumen, and thus turn yellow. The solution used here is to put down temporary markings (or leave the road unpainted) until a couple weeks have passed. While ideally the temporary markings would meet the same standard that permanent markings do, it's common practice to just put down spraypaint marks or little squares of reflective tape every hundred feet or so. As for the scoring, that's a recessed groove that protects the final markings from road wear, especially plows. It's not particular deep, only about as deep as a US quarter, but that's plenty to keep the markings fresh for about twice their normal lifetime. You'll see the final pavement markings laid down in the scored areas.

Maybe some science goon can answer a question about indoor humidity The AC went out at my house and I have to wait a while for a new HVAC system to be installed. It's murderous hot out so I got a couple of window unit air conditioners to keep the place bearable in the meantime. The units work okay, but for some reason this has made the inside of my house unreasonably humid. Like 80% humidity, even when it's 50% outside. What in the world would cause such a thing?

What do you think Bill Cosby's legacy will be, say in 20-30 years? It should go without saying that he's a despicable person and I in no way support him. It's also undeniable that he's one of the most important comics of all time. I ask because if we look at other terrible but talented people, the talent seems to win out sooner or later. Richard Wagner was a huge anti-semite and all around terrible human being. He's also one of the "big 3" opera composers and every major opera house will perform his operas regularly. Louis CK is probably the best stand up of his generation. His show Louie was one of my all time favorite shows. And he's releasing new material, but it's very uncomfortable for me to listen to and I can't imagine going back and watching his show again. John Lennon definitely cheated on his wife and allegedly beat women, and never really took a hit to his reputation. Any classic hits radio station has no problem playing Imagine. Roman Polanski might be the closest parallel -- he, like Cosby, raped a woman (in his case an underage girl) and from what I can tell his current reputation is "well, he's a garbage person but his films are still of value and worth watching". So, will that happen to Bill Cosby eventually? I find it hard to imagine. I can't imagine watching Himself ever again even though watching it in 2008 with my then gf, who had never seen it and only knew Cosby from his tv show, is a great memory. She was laughing so hard she almost threw up. So, given another couple of decades, will people say "eh, he's a terrible person but the work still has value"? Seems hard to imagine. This might be a better topic for GBD or D&D but thought I'd ask here first.

I can't speak for the internal culture of stand-up comics, but I don't think Cosby is relevant even now as a comic, only for the Cosby Show, and actually watching the Cosby Show with his behavior in mind is pretty uncomfortable for a lot of people, and probably should be. I think in a class about the development of TV and sitcoms and the influence of culture in the 80s into the 90s, the Cosby Show is going to be pretty relevant, and will still be shown, but I really doubt it'll be watched or binged as entertainment in the future.

Do you really think so? My memory is that prior to everything that happened he was considered one of the giants, in the pantheon with Carlin, Lenny Bruce, Pryor, maybe one or two others. Young comics would talk about playing his records over and over again when they were kids, things like that.

Again, I can't speak for the internal culture of comics, but I think Pryor or Carlin are much more relevant currently. I don't want to use the word "influential," because Cosby's certainly still influential now, but I think it's in a more indirect way. People who are young right now can find Pryor or Carlin and have it resonate with them, but I don't think people currently resonate with Cosby's own stand-up material itself. There's definitely going to be exceptions. Maybe I should say "I don't think many people currently resonate" or something, or that significantly fewer will than with Pryor or Carlin.

I get what you're saying and you're right that the current state of comedy is more in line with Carlin and Pryor. My line of thinking was more along the lines of, Bob Hope, Jerry Lewis, and George Burns are not culturally relevant the way George Carlin is but are still respected and probably to some degree studied. I can't imagine that being the case now with Cosby, even though his comedy chops were at least on their level. And if it were possible to watch neutrally, Himself is still (in a vacuum) one of the funniest standup sets of all time. I wonder if it will be forever tarnished despite any technical merits, ala Birth of a Nation or the works of Leni Riefenstahl, or if it will be appreciated with the caveat of what a terrible person he was, more akin to Rosemary's Baby. It's interesting, Robert Blake in Lost Highway doesn't bother me too much but I can't watch the Naked Gun movies. Maybe because OJ has a bigger role than Blake?

Manager Hoyden posted:Maybe some science goon can answer a question about indoor humidity This is why relative humidity is generally not helpful. Dew point is the temperature-independent measure of moisture in the air. For example, 90 F with 50% relative humidity has a dew point 5 degrees higher (and thus, more moisture in the air) than 70 degrees with 80% relative humidity. You can Google "dew point calculator" to play around with the numbers.

Thanks for humidity chat y'all. One of the ac units was a portable (the kind that sit on casters in the room and vent through a hose out a window slat) and apparently those don't work as a rule. I replaced it with a regular window unit of the same ashrae rating and the temp dropped five degrees and the humidity in the room dropped twenty points.

So, long story short, I do a lot of Chinese-English translation on the Google Translate app and vice versa. This morning, there was some kind of notification I skipped over in my rush to translate something and now I can't find out what it was and it's really annoying me. It was a yellow-ish box below the main translation entry box with I think a cartoon loaf of bread character trying to remind me of something. Maybe something I did previously? I only saw it for a brief second and I swear I'm not hallucinating or making this up. I've never seen this kind of notification like this before on the app and I'd like to find out what it was. It'd be even better if someone could get a screen capture of it. Teriyaki Koinku fucked around with this message at 04:04 on Aug 14, 2021 |

Re: the Cosby question, I recently watched a retrospective on The Cosby Show that goes into his past and influence that I thought was pretty well done. It's more about the show than anything else but as somebody who grew up watching and enjoying it I found it kind of cathartic: https://www.youtube.com/watch?v=khIS98DltT8 Frankly I had no idea how huge he actually was prior to the show getting made--my frame of reference was entirely the syndicated run on Nick at Nite as a child--so I appreciated gaining a greater context. I think it's far more likely he will be remembered and regarded in the same way as Polanski instead of Lennon, if he is remembered for his artistry by future generations at all. This would also be an interesting topic for the Sexual Assault/Culture of Hollywood thread in CD (you can find that here)

Do you want to set up a home planetarium or what? Try the free software Stellarium for an accurate view of the night sky at any place or time on Earth (and places not on Earth). It’s easy to project that onto a flat wall, somewhat more involved to build a dome to make a real planetarium. You could also try VR goggles.

This question might not be small or stupid: I've always been taught that insects are limited in size because they use surface tension and other related laws of fluid dynamics to transport fluids through their bodies rather than peristalsis like vertebrates. If that's true (I guess it might be a simplification), how was it possible that three foot long dragonflies existed in the carboniferous period? I know the air was different, but as far as I know that was only the composition of the gasses, not basic things like air pressure that would change how fluids behave. Wikipedia kind of touches on this, describing it as an open question with one outdated explanation, but then switches over to 'how where they able to fly' and what evolutionary niche they filled, conflating all those issues and leaving me still wondering how their physiology worked. Is there something online that goes over the debate and some theories in more detail that I could maybe read?

I was always lead to believe insect size is limited by oxygen concentration, since they rely on simple diffusion of oxygen into their hemolymph instead of using any sort of ventilation. Higher atmospheric O2 concentrations meant higher blood O2 concentrations for insects, which allowed them to maintain larger body sizes.

So is that a thing where you could put existing insects in a high oxygen environment and they (or their offspring) would just grow bigger, like how goldfish get huge if they have enough space, or is it limited by their genetic blueprint?

Coconut crabs don't breathe through trachae like insects do so there's no reason they can't get huge. From what I remember, you do get bigger insects in higher O2 environments, but they don't get to be as big as the 3 foot long dragonflies of old so I think it's both genetic and environmental.

The more I read about this, the more I think it has to be a combination of everything: 1. More oxygen means less energy used for the tracheae, leaving more energy for growth; 2. Size isn't risky (particularly during molting) if there are no predators (birds) yet; 3. More oxygen means it's easier to fly, making it less useful to stay small. Maybe that 3ft dragonfly was pushing right up against the bounds of size based on hemolymph flow, and then the oxygen levels dropped and birds and lizards started eating the biggest insects and because of those two things size became a disadvantage. It's too bad we can never breed enough generations of dragonflies (or any kind of insect) in an oxygen rich environment without predators to find out how big they would get again.
