Water entering your body with a trace mineral deficit will dilute the mineral content of your body, and you'll excrete these minerals every day in your urine.

One day or one week doing this is no big deal, but if it's your main water source and you do it all the time, you will start demineralizing your body and you'll be short of electrolytes which is known as hyponatremia.

Went to the opthamologist this year cause I could tell my vision was worsening.

After all was said and done they ushered me into their eyeglasses store which was physically connected to their office. A nice friendly man told me the frames start at 299 and go up from there.

I said thanks man with this eye exam I can barely open my eyes so I’ll come back.

Got two pairs of awesome glasses from Zenni for $55 total.

I’ve read this is online movement is destroying the career of optometrists. Also the eyeglasses scam also seems to be connected to Luxottica which is a well known sunglasses scam also. I will continue to buy from Zenni
I was curious what kind of scam this guy was going to move onto next.

Take your anecdote and replace "water" with "electromagnetic waves."
People tend to get a lot of sodium from their diets making the sodium content in their water a non issue. The same is generally true of most other minerals, unless your diet is horrid the water you drink is not going to make a meaningful difference.

"Answer+comments"(Quora,Stack*) vs "comments tree"(HN,Reddit)
It seems like what the UK government is saying is:

A. Either we outsource security-related tasks onto you, as companies (which I think has huge ramifications), or:

B. We shake you down as a penalty (arguments about whether the tax should be paid already notwithstanding).

The consequences of A, alone, are worth an entire discussion. It means compromising everyone's security to some extent, and having these companies as active participants in the security state (or perhaps, more than they already are...).
Wouldn't treble fix the Android fragmentation problem ? Why is this needed/better ?
This just seems plain stupid to me. How can a government not provide one of the most basic, most essential services that we even see as the first thing to provide to third world drought-ridden places? There are a ton of NGO's in the USA that (so they say) make wells and clean water available in Africa, but when it comes to tap water at home it is so bad that people turn away from it and away from the scientific backing on how tap water should be.

It always amazes me that in some countries (or areas within those) you still can't expect safe tap water, and still have a large 'bottled water' industry and consumption. It doesn't help anyone and it doesn't align with the idea of setting up a specialised entity and supply them with resources to do it (a.k.a. water supply company and governing instances).

We expect normal, clean water that is just water and not added with anything for 'our benefit' out of the tap, and that's what we get. It's tested, and there are multiple different grids with individual sources and individual filters. It's not hard to do, it's what we have here; it costs almost nothing, and doesn't fail. Strangely enough, one neighbouring country (France) doesn't have this uniformly (don't drink water in Paris...) but in another (Germany) the water is just fine again.

You'd think that a civilised country that sets up organisations and systems to deal with basic needs at scale would be able to accomplish their designated tasks.

I'm not really a fan of your "best practices". Java often has unique problems where this generic advice breaks down (I do a lot of low latency and high performance work), and sometimes you need mechanism sympathy instead of relying on tools so much.

1- The author does tell you to understand your hot path. However in Java it is often difficult to pin down GC related issues and just easier to prevent them in the first place. I've tried to go through code bases others have written top clean up allocation problems and they become so embedded in the code that it is easier to just rewrite. Or some issues like finalizer/weak ref issues are very difficult to find in your measurements.

2 and 3- I've never seen this work. This is a great way to get a bunch of faulty analysis or not even know you're going off track to begin with.

This article and many of the tips are written when you are trying to be "as fast as possible" and where each microsecond counts. I've seen a lot of projects go down in flames where they treated performance as something secondary the can be written into the code in a second pass. When you ate having to deal with issues like the article describes you should take a more first principles approach and keep your eye on the proper idioms inn the first place.
quote from the article:
"Even using precise measurements, which we’ll get to in a second, your new virtually-bought glasses can turn out to be uncomfortably tight, annoyingly loose or simply ill-fitting, regardless of the stated measurements"

Which was my experience. Apparently I have an extra wide head, so even the widest frames didn't fit right. Since I only need the glasses for seeing details, it is not that big of a problem, but I spent a lot of time measuring my head and eyes to get a bad result.

Maybe Apple will build a 3D head modeling software into the IphoneX and revolutionize glasses! a new app idea!

In the meantime, I just increased font size on my monitor!
In 1832, there was a cholera epidemic. Thousands of new cases each week and hundreds of deaths. When it hit Paris alone, tens of thousands of people died. To quote a former mayor of New York at the time:

> Our visitation is severe but thus far it falls much short of other places. St. Louis on the Mississippi is likely to be depopulated, and Cincinnati on the Ohio is awfully scourged.

Over a hundred thousand people fled urban areas to live in the countryside to escape cholera. Hundreds of thousands of Europeans died of the disease. Our former president, James Polk, succumbed to the disease. Almost a quarter million Mexicans died. Millions of people contracted cholera around the world and hundreds of thousands of them died.

We don't really have cholera anymore. Fewer than forty cases have been reported in the US each year for the last fifty years or so. This is largely due to our ability to treat water.

You know who doesn't have treated water? The Democratic Republic of Congo. Ever hear about the water crisis in Africa? Tens of thousands of people contract cholera there (among other other diseases) each year, and a good chunk of them die.

> Transparency drives technological evolution, if the tradeoff is known and can be argued to be problematic there is an incentive to come up with a better solution.

Drinking untreated groundwater is not the answer, and not innovative in any way. It's regressionist. Encouraging other people to do it with promises of potential health benefits is ignoring our relatively recent past, where literally millions of people died because we didn't have clean tap water. Perhaps we've lulled ourselves into a false sense of security, not having to worry about dying from terrible waterborne diseases.

Also, fluoridated water doesn't decrease your IQ [0], and claiming it does is irresponsible.

I'm sick of hearing about white males. Just because they dominate leadership roles doesn't mean that all, or even most white males have power. It's gotta be less than 1% of white males who have a position of influence. It's not a collective group.
> If I were to speculate, I would say that we are overwhelmingly better in our general mental health.

By what measure? Because I just posted a bunch of studies that show the opposite, and they actually address a lot of the issues you brought up.
There is a "Report incorrect product information" link on each product page, and someone does read what you post there. I've reported a few products where the name didn't match the picture or description, and they were fixed within a few days. Whether they would care about a less obvious problem, I don't know.
I recognized the fact that humans are the lying species a long time ago, and I've tried to counteract that in the workplace. I find opportunities where I can naturally push the boundary a bit, which isn't too hard for a young male with nothing to lose. I do it both for myself and to create room for others to rightfully express themselves and be able to get away with it.

It works a little bit. People are still very protective of their position, but I'd like to think people on my team are a little more open about things than when I started. I don't have a way to measure that, though. I can say for sure that we're much more trust-based than when I joined.

The truth is a funny thing, literally. I'm not a naturally funny person, and the jokes that I make are often one that only I seem to understand. But it's when I'm honest about things that I get the most laughs. I remember one time when the conversation I was having lead me to say "Some of Charles Manson's music is pretty good" to this one woman, and she laughed at that but I don't think she realized that I meant what I said.

Given that kidneys are responsible for filtering excess electrolytes out of the bloodstream it makes sense to me. A person with compromised kidney function may need to limit intake to a level that the kidneys can handle. This doesn't necessarily mean that a person with healthy kidneys needs to limit intake.
My first paragraph wasn't describing what ought, but what is.

> stop and frisk statistics in NYC indicate the opposite. Besides, why does that even matter? Even if most alleged perps are guilty of something, that "something" isn't usually a violent crime, it's a traffic violation or public drinking or selling pot or a minor domestic disturbance

Without refuting either of these points, I stand by the intuition of my comment. Stop and frisk seems more like an exception that proves the rule, showing just how bad the narrative of "good guys" "inspecting subjects" has gotten.

> That comes from the attitude that asserting control over the situation is more important than protecting and serving the citizenry as the cop was hired to do

I totally agree - focusing on their desire for control, and the injustice committed when they demand that control over an innocent person, is a good way of analyzing it.

> the case of this SWAT call, the cops had plenty of time to secure their own safety and to wait out the hostage taker. First and foremost they did not even confirm

IMHO, the "in-situation" framing is heading down the wrong path. Primarily worrying about what the police department policy is, how much of a paid staycation a murderer will get, etc is buying into the corrupt idea that cops aren't subject to the laws themselves. Under the actual rule of law, murderers go to prison no matter what costume they wore. And if policy department policy encouraged/defended the murder, we call that conspiracy.
Is this really a consideration outside of cases where someone is tuning their system so that it never does garbage collection?

Dunno, I can't imagine most men actually preferring masturbation over sex when given the choice. Most men would consider themselves in a spot of sexual destitution if all they were doing was wanking.

I think more likely the modern male is barraged by messages like "approaching women is 'rapey'/creepy." And it's easier for people to get by without developing social skills. If men aren't approaching women, then nobody gets laid.

I reckon there's a gradual collapse in the confidence and self-identity of the modern western male that can be tied to some sort of Everyone Loves Raymond emasculation slash feminization going on in our culture.

For example, along with these positive women's rights messages that most men support, there also are messages that look a lot like women-can-do-no-wrong which end up alienating men. Or something I can only describe as male-shaming. https://www.wsj.com/articles/SB10001424052748703779704576073...
Do these online places include prescription lenses in their low quotes, because that's where the bulk of the cost is in most cases.

I picked up glasses at Costo in 2016 and the cost was $237 which included an exam. Here's the break down:

- $49 eye exam

- $39 for the frames

- $149 for the prescription lenses

- $0 hard case and a microfiber cloth (it comes as a bonus)

I paid a premium for the lenses because they are of the light weight material that's also scratch resistent and turn into sunglasses when exposed to UV light. The transition lens coating alone was like $49 but since I go outside a lot it's totally worth it.

I don't know the details of your experiences, but I've learned to not consider that kind of rejection to be a bad thing. Rather than try to please everyone and be mediocre(and unmemorable), I would polarize people so I can know which people might become real friends and weed out those who wouldn't accept me for who I am. A lot of people don't like me because I refuse to act out a personality, and I don't mind that. Most people are a waste of time.

That's not to say that I never lie, but I keep my lies relatively harmless. 90% of the few lies I tell are really lies by omission, and the remaining are just exaggerations around true stories. People just enjoy a good story, and it's my job to make those stories entertaining.
> In fact, it conferred a resistance against malaria.

I think this is one of my main points: if such a large percentage of the population has something that we think of as a large negative, it's probably a good time to take a step back and wonder if we aren't understanding the whole picture because evolution tends to take care of such low hanging fruit.

That's insane! Jail-time for talking to a girl?

How did society get this fucked up, so that a guy should be scared of talking to a girl? I know you said "hitting on a girl", but you have no way to know if the girl will misunderstand you trying to have a friendly conversation with you coming on to her. Best advice is to stay far away from women in all aspects of life.

Kay makes a distinction between invention and innovation. Invention is the creation of qualitatively new things and innovation is the betterment of pre-existing things. The AI research that’s happening now sounds more like innovation. Innovation is fine, but civilization-changing things (like the constitution or Internet) are the result of invention, not incremental improvement (to paraphrase Kay’s argument).
Here's one such (meta) study: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3491930/#!po=58...

Note that it focuses on child development and several of the included studies have populations which rely on water sources contaminated way beyond typical fluorodation (up to 10mg/l vs 1mg/l).

Also we're talking about a small difference in IQ (-0.5 point, still very costly in personal and societal terms); nothing about making populations docile.

> less than 1% who have a position of influence

A big part of “We are the 99%” is, surely, the realization that less than 1% of all people have those coveted positions of power. If they followed the same distribution as the population as a whole, which they don’t, something like 61.3% of that 1% would be white, 13% would be black etc.

The distribution is heavily skewed towards white because for historic and cultural reasons it’s much easier for white people to get into that group.

> it’s not a collective group

Welcome to *ism 101. That’s when the properties of a minority are expanded to the whole group based on a trait. All white men are terrible, all black people wear saggy sweatpants, all hispanics clean toilets, and all white women want to speak to the manager Etc

He also follows these things up with canned strategies to make your life antifragile, without making any attempt to demonstrate how or why these strategies are actually so.

Example: he does not recommend the standard investment strategy of purchasing stock funds and bond funds at a ratio that approximates your tolerance for risk. This is, for some reason, fragile. He recommends putting most of your money into the safest investments available on the market, with the rest of your money going into the riskiest moonshots you can find. This is, for some reason, antifragile. "Unimportant" questions like why and how these strategies are classified as fragile/antifragile and what kinds of investments he considers appropriately safe are left as an exercise to the reader.
