I watched a documentary on this awhile back. The municipality asked the public if it would be enough for them to dump treated water into a lake and then draw from that lake? And then someone with expertise in the matter commented that this would necessitate another treatment phase, since any wild animal could take a dump in the lake. So he seemed to think closing the loop made the most sense from a practical standpoint.

I think people here tend to question and fact-check posts and comments a lot, which is a healthy thing. Now some say reality skews left, in which case could it be that the right have left because the left is right?

literally good for you

I actually asked my family doctor at one point about the health effects of masturbation. She said that as a guy, if you are not otherwise sexually active, it’s good for the prostate to keep the plumbing working down there.

I started in C and switch to C++. It’s easy to think that the latter sort of picked up where the former left off, and that since the advent of C++11, it’s unfathomably further ahead. But C continues to develop and occasionally gets some new feature of its own. One example I can think of is the restrict key word that allows for certain optimizations. Afaik it’s not included in the C++ standard to date, though most compilers support it some non-standard way because of its usefulness. (With Rust, the language design itself obviates the need for such a key word, which is pretty cool.)

Another feature added to C was the ability to initialize a struct with something like FooBar fb = {.foo=1, .bar=2};. I’ve seen modern C code that gives you something close to key word args like in Python using structs. As of C++20, they sort of added this but with the restriction that the named fields have to come in the same order as they were originally defined in the struct, which is a bit annoying.

Over all though, C++ is way ahead of C in almost every respect.

If you want to see something really trippy, though, have a look at all the crazy stuff that’s happened to FORTRAN. Yes, it’s still around and had a major revision in 2018.

I think I could get very nervous coding for the military, depending on what sort of application I was working on. If it were some sort of administrative database, that doesn’t sound so bad. If it were a missile guidance system, on man! A single bug and there goes a village full of civilians. Even something without direct human casualties could be nerve-wracking. Like if it were your code which bricked a billion-dollar military satellite.

Speaking of missile guidance systems, I once met someone who worked a stint for a military contractor. He told me a story about a junior dev who discovered an egregious memory leak in a cruise missile’s software. The senior dev then told him “Yeah, I know about that one. But the memory leak would take an hour before it brings the system down and the missile’s maximum flight time is less than that, so no problem!” I think coding like that would just drive me into some OCD hell.

I have only written potentially life-threatening code once in my life. It had to do with voltage/current regulation in the firmware of a high-powered instrument used by field workers at the company where I work. It was a white-knuckled week I spent on just a single page of code, checking and re-checking it countless times and unit testing it in every conceivable way I could imagine.

Fair enough. I’m just looking for some independent confirmation as this is pretty big news.

Is this official though, or wishful thinking on the part of Cameron?

I remember ads claiming it was cutting edge nanotechnology! And I thought oh cool, you mean like there are tiny robots running around in the shampoo? But no, it was microplastics.

This happens naturally in the form of meteors streaking through the sky. Each one of those is adding a tiny amount of mass to the planet.

But you’ve got me wondering about something now. When a large asteroid hits the planet, it obviously adds its own mass, but it also kicks up a lot of debris into space. Some percentage of that will reach orbital escape velocity and never come back. But I honestly don’t know if there is a net mass increase or decrease after such an event? We’re generally concerned about other more pressing matters in such a scenario!

From what other posters are saying, it may be the other way around? That is, most mammals cannot see green, so it doesn’t matter from a camouflage perspective among mammals. Humans (and primates in general) are an outlier in this repect.

Bird of prey can, though, so there’s that.

Wow, that is fascinating!

Makes me wonder about the other direction, going into the near infrared as opposed to UV. I remember from a class in remote sensing that many plants are actually most reflective in that band (more so than in green, even). NIR air photos are often used by biologists to get an indication of the health of a forest. But I have no idea whether animals also reflect NIR? It may be that most animals cannot see in that band in the first place, so it would not offer any camouflage advantage.

Great read! That explains a lot.

I’ve been deep diving a bit myself and found this article that explains another thing that’s puzzled me over the years. Some birds have crazy vibrant coloration that almost glistens, like peacock feathers. Outside of the zoo, I’ve noticed it a bit in common grackles. They look black on first glance, but when you study them closely, they have this kind of purple sheen around their heads. Apparently, it’s still melanin at work here, but it’s structured in a very special way.

Right? I guess that’s what puzzles me the most about it. It must be really hard for mammals to become green since you would think it would confer an advantage in many environments you find them in.

I guess there are a lot of mammal species that kind of make themselves scarce during the broad daylight hours, so maybe green camouflage is less relevant if you’re only out between dusk and dawn?

Yeah fair. I had painted glass fish in my aquarium at one point and discovered the “paint” came from feeding them dyed food and eventually faded away when I gave them normal food back at home. They are naturally transparent for the most part which, frankly, I thought was cooler. I did have a gourami that was legit green though, as far as I could tell.

Ha!! You really had to go down the “rabbit hole” for that one I bet! Awesome.

Yeah, I’m a big believer in shade trees! The one in our front yard has grown tall enough to provide blessed relief from a blazing afternoon sun. The only problem is the dude next door, who’s heavy into solar, is worried it’ll block his panels. And I’m a believer in solar too, so I don’t know what to say. Maybe we can come to some sort of compromise…

The Internet needs to be capitalized.

That’s why we need passive daytime radiative cooling. In theory, it could completely eliminate the urban heat island, but it still seems to be mostly at the pilot project stage so far. I did read somewhere that you can DIY with some packaging tape (which somehow has the right properties?) over a reflective backing. Maybe I’ll experiment a bit this summer.

Yeah, one context in which a subject is not required even with proper English grammar is in imperatives, which makes sense given the implied urgency. If “Watch out!” had to be something more long-winded like “You must watch out!” you’d probably be dead.
