Copper is used as bottom-coat on sailboats, it's also used as a non-hormonal contraceptive IUD material.

I don't think it's terribly harmful for humans if it's safe for a women's uterus. California tends to be exceptionally concerned for the environment in general. All that copper dust making it into the coastal marine environments isn't going to be good for it, considering the same stuff is used to keep marine life off boats.

edit:

"The issue has been under consideration since the 1990s, when cities south of San Francisco were having trouble meeting Clean Water Act requirements to reduce copper in urban run-off flowing into San Francisco Bay. Preliminary studies indicated that brake pads were a significant source of copper in that runoff. Tiny amounts of copper fall onto the streets and parking lots every time drivers step on their brakes."

As I suspected, it doesn't appear to be primarily a human toxicity concern. It's to protect the marine environment.
I saw something similar recently when reading JSON data from postgres via Rails, which was unbelievably slow. I found the reason to be that Rails would automatically parse the JSON value into a in-memory ruby object. Since this was for a API-like backend, the solution was simple: just read the column as a string ("SELECT payload::varchar..")

I don't know if dkango is doing the same, but using an ORM might just do that to you.
People care about both.

Getting money without a promotion is obviously welcome, and so is getting a promotion without salary increase.

Of course a promotion is marketable on one's CV so it helps people getting a fair salary elsewhere if needed... An ambitious person might therefore give priority to increased responsibility and higher title than to immediate financial gain.

Sure, I see where you're going with that. Miami, a fully-furnished house that is expensive for the sake of being expensive, filled with items that can be converted to clean, legal cash with minimum overhead once the home is purchased. The irony is that a home intended for money laundering was bought by a guy that got boatloads of clean cash dumped on his head, wondering what to do with it all.
Dick Swaab of the Netherlands Institute for Neuroscience is a pioneer in the neuroscience underlying gender identity. In the mid-1990s, his group examined the postmortem brains of six transgender women and reported that the size of the central subdivision of the bed nucleus of the stria terminalis (BSTc or BNSTc), a sexually dimorphic area in the forebrain known to be important to sexual behavior, was closer to that of cisgender women than cisgender men.[1] A follow-up study of autopsied brains also found similarities in the number of a certain class of neurons in the BSTc between transgender women and their cisgender counterparts—and between a transgender man and cisgender men.[2] These differences did not appear to be attributable to the influence of endogenous sex hormone fluctuations or hormone treatment in adulthood. In another study published in 2008, Swaab and a coauthor examined the postmortem volume of the INAH3 subnucleus, an area of the hypothalamus previously linked to sexual orientation. The researchers found that this region was about twice as big in cisgender men as in women, whether trans- or cisgender.[3]

> Having watched a control group lose 70% of the people while the people getting the real drug survived is just inhuman.

Again, at this stage you're just assessing if the treatment even works. The point isn't to fix one group and screw over another, the whole point is that you don't know if the drug is going to do anything. It's much easier to tell if a treatment is worth giving to everyone if you first do the correctly controlled trials.

It seems like you're coming at this from a place of assuming the treatment is going to work from the get go, which is not true for the majority of treatments that undergo this kind of trial. Moreover, many treatments have side effects that, again, are much easier to look at if you can compared them to a group that went through the exact same handling. Even small, seemingly innocuous things like going to a hospital to talk to an interested person about how you're doing can have an effect on health readouts that may be relevant to a study. Or maybe the stress of sitting down having this weird hat put on your head affects something. Or maybe some much less obvious aspect of the study. The point of the control is that you cancel out all of these kinds of effects, obvious or otherwise, so that the ONLY difference is the treatment.

Controls also help with allowing double blinded studies. If the researchers know who is receiving treatment and who is receiving placebo, they can unconsciously influence the results, especially for things like behavioral surveys that aren't as objective as, say, taking blood and seeing if you have more or less cancer cells. Obviously you can't have this kind of blinding if the researchers know every single person is getting the real treatment.

There is an expedited review process for this kind of thing. It’s impossible to tell who is to blame here. It could be that they abused the expedited review process before and are excluded, or they never requested it, or perhaps they were late in sending in the new version.

Vultures play a critical role in disease control and waste removal. They are actually one of the most important scavengers in Africa and are believed to consume even more carrion than mammalian scavengers like hyenas. Vultures also eat rapidly and feed in large groups which allows them to consume carrion quickly. This reduces the risk of disease spread from flies or bacteria. Vultures are resistant to many diseases so they don’t contract or spread diseases like tuberculosis or brucellosis even if the animals they are consuming died from those causes.

My impression (based on having interacted with a lot of teachers, including friends and family members) has been that teachers' unions are "those mean ol' ones who get teachers way more than they deserve", but only for those teachers with a substantial amount of tenure (on the scale of multiple decades).

they were. But they used asbestos in a lot of things back in the day. I worked in a building with asbestos in the floor tiles. When they did constructions that involved removing the tiles, it became a big deal.

Asbestos isn't that harmful, until it goes airborne. My understanding from research (I worked expanding a landfill that took asbestos at one point). is that the particles are too small to be caught by our bodies defenses and when it ends up in your lungs its cancerous. Asbestos in brakes seems like a bad idea.

Game Theory on the “Second Civil War”
>Tend to resemble that of the gender that they identify as

I hear this claim a lot but I've never actually understood what "resembles" actually means. The brain structures that transgender people have don't match typical male or female brains but how do you determine which brain transgender brains resemble the most? What is the criteria? To me to determine which brain trans brains were more similar to you would have to study a LOT of dimorphic brain structures.

Some structures in transgender brains do resemble their sex or are sort of androgynous and inbetween. So I don't know how accurate trans woman = "resembles" a woman's brain actually is as a sweeping statement. In my experience trans women have rarely acted completely like either gender. I've seen trans women disperportionately engaging in masculine hobbies like computers compared to the average cis woman.
What on earth is about marketing to women now and using the promise of finding ones 'tribe'? It's really cringey and fake to me.

How is this not a caricature of HN readership and geeks in general? Some/most people might even tell you that the purpose of life is to socialize--and all the games/power plays around that.

To add more information, FB doesn't actually connect you to 200-2000 people literally. When you think of RSS, you think of seeing every single article that you subscribed to, but FB doesn't do that. It shows you only some of the what others publish, and it uses its dark algorithms to make sure those are the most engaging and addictive stories (reposts of click-bait titles, trending gossip, politically divisive arguments, etc.). And then it pads the feed with ads and more click-bait.

Actually the "genius" of FB is to tap into the social-reward centers of the brain by letting you inflate the number of friends, the number of followers, number of notifications, while still trimming down the firehose of pictures of your second cousin's roommate's tacos. Conversely, it lets you post your food pictures into the void and feel that others care about it, without actually bothering too many people.

To answer your question directly, yes these people spend inordinate amount of time doing this, but I believe they feel it is a good thing, to have a big social circle and feel connected to all those people--without always seeing how they were manipulated into being addicted to something that is not real socialization.

Well given than in Spain vultures are feeded by the remains of butchers, while in Portugal those remains are burned down(I believe), it is not a big surprise.

I have seen them being feeded in mountains at the north of Spain called Picos de Europa:
https://en.wikipedia.org/wiki/Picos_de_Europa

Laws change abruptly across boundaries, so it is not a surprise that vultures know when they are feeded or not.

Birds or animals are not stupid. Animals that are hunted know exactly when the hunting season starts and ends. I have seen deer separate in sexes when the hunting ban expires(because the law forbids females to be hunted down), so you will see females with offspring completely relaxed in front of people.
There is a word/name for that phenomenon though it escapes me right now. That said, in this case I think many/most people assumed the correct answer (or something close to it) prior to the grand reveal.

> Certainly there are many ways you could talk to someone about a menu: what kinds of dishes are there? Appetizers, grilled entrees, pasta, salads, desserts. What kind of entrees? Vegetarian, pork, beef, seafood. OK, but what styles of cuisine? Jamaican, Italian, Szechuan. There's probably an analog to the 5 Why's for figuring out what someone wants to eat!

To me this is the core of why voice interfaces will always be inferior. In the time it would take that voice conversation to happen I would have been able to scan a menu a dozen times over. Our brains are incredibly adept at picking out visual details - identifying the headers that note each section of the menu, picking out key words that may interest us and so on. There is no technological improvement that will help a voice interface rival that.
