Good questions and I'm curious on the actual science too.

We're using liquid pool chlorine diluted with water -- pool chlorine is just higher-concentration bleach.

Although not scientific by any stretch, I know that the general guidance (and my experience from chlorinating & testing pools) is that you want to check the dates on the chlorine when purchasing because the strength can be substantially lower than stated if it's been sitting on the shelf for a long time. My understanding is that the effect is worse if the product has been sitting outside in direct sunlight / high heat (ie outdoors at a home improvement store), which I believe causes concentration to drop faster.

If you're having trouble finding bleach though, likely can get some at a pool store or a big-box home improvement store in the pool chemicals area. We just mix it down to suitably diluted concentrations in a spray bottle -- readily available & much cheaper than off-the-shelf spray products. I wasn't aware it might be 50% lower concentration in 30-days though, will have to re-mix ours here soon. But that's still small potatoes overall, a gallon of bleach goes a long way and has lots of uses. :)

What I wonder is whether they are aware of it or do they operate under a sort of doublethink.

Doesn't someone realize that hey wait, what I am doing to them now is what others did to us/our ancestors. Shouldn't that stay your hand instead of justifying it.
I think you summed it up perfectly. I was an early adopter, but the iPad never worked for me. I'm more likely to crave a MacBook Pro I could put in my pocket than a constrained oversized iPhone with a big screen and a keyboard.

He means Milton Friedman. The "theory" itself is called

> Distrusting social skills, linguistic ability, and emotional intelligence doesn't sound like a recipe for success.

It's not a matter of "trusting" vs. "distrusting" them. It's a matter of what universities (and other exclusive institutions, for that matter) select for. If you select for "social skills, linguistic ability, and emotional intelligence" without also having any objective way of measuring actual productive potential, not to mention evaluating a person's actual willingness to use their talents in support of a cooperative civil society, you're going to get a lot of people who will be very good at preying on others and using the system they are gaining entrance to as a tool to that end.

> It's not like there aren't plenty of engineers, scientists, math folks, i.e. those "honest", quantitative folks, who aren't also crappy or deceptive people

Yes, that's true, but without those social skills they do a lot less damage, because they can't get very many people to interact with them.

I don't have a direct lead for you, but this sounds like it's tracker music (music written on Modtracker, Screamtracker, Impulse Tracker, Fasttracker, etc.) - I'd hazard a guess that it was recorded in the mid-to-late 90s.

Unfortunately, the only clue you have to its origin - "candyman" - is the name of a film being actively promoted right now, so it's going to be even more difficult to chase down than it was even just a few months ago.

It's possible that the name of the MP3 is a reference to the person who wrote the music, or it could be the name of the song they wrote. I've found at least five different "candyman" musicians doing tracker music, demoscene music, cracktro music, etc., the actual files are hard to come by, and the music I do find is techno, but not the same genre.

I could see the tune you linked being played over the end credits of some demoscene disk.

Anyway - I'm pretty sure that what you're listening to is an MP3 of a tracker file.

Every little bit of information helps :)

The OP mentioned in another reply that their submitted title did include a (in Haskell) at the end, and it was dropped (automatically?)
I'm going to take inspiration from @lexi-lambda and respond in mini-composition form. Note that great writers write essays. I, write compositions.

It's just like Haskell for the crucial difference between two functions to be denoted by prime. For half of the essay I thought that this was a deep philosophical treatise about the degenerate case equality of lazy and strict languages. But, in reality, fold and fold-prime (can you inline code in HN?) are totally different functions.

And like with all pairs of things in Haskell once you learn the fundamental difference between them, the fact of that difference becomes obvious. So obvious that you don't know how anyone could possibly confuse the two. And so you call the method everyone should use foldl-prime even though a casual programmer doesn't even know that "single-quotes" are an acceptable value name. When you could have just called it foldl and moved the old one to the deprecated module.
> Rust has a lot of things that C doesn't, like classes, lifetimes, and the borrow checker, which can be jarring to deal with for programmers used to other languages.

If you are a competent C programmer - the kind that "doesn't make" memory errors, you have to be manually keeping track of lifetimes and borrows.

Rust takes that mental effort and offloads it to the compiler.

Lifetimes and the borrow checker will likely be jarring for people coming from languages where you don't need to worry about memory allocation and ownership, but if you are coming from C or C++, you will likely find the borrow checker a relief (I did).

> the compiler won't let you do the "bad" things, so you have to get everything write from the word go.

And it's wonderful! Finding and fixing problems at compile time is the fastest and cheapest way to do it, and is also a productive way to refine your abilities.

Which argument are your referring to? Do you mean the Münchhausen Trilemma or the comment to which you replied?
No, the Stark Law prevents that (self referral, referring to another business the physician has a stake in) https://en.wikipedia.org/wiki/Stark_Law . Physicians are paid according to a fee schedule that decides how much each thing they do is worth. Each procedure or office visit is assigned a work Relative Value Unit, which is multiplied by a conversion factor ($36.0391 for Medicare) to determine how much a physician gets paid. Private insurance generally follows the Medicare RVU scale, and has an adjustment ~120-150% for the conversion factor (just a guess, only a student). This conversion factor was $36.6873 in 1998, so, adjusting for inflation, Medicare values each thing a physician does at 62% of what it did in 1998. I hate that most of my posts on this site are about this topic, but so many people on this site get it so wrong when it comes to how physicians are paid.
Lawsuit Accuses Facebook of Knowing Ad Audiences Were Inflated
Well... there's a lot to unpack there, no pun intended.

The two things I'll say:

- First, it is very possible to use React without all of those dependencies, although it does mean skipping `create-react-app`. That could be a longer conversation in and of itself and going that direction comes with its own set of benefits and tradeoffs.

- Second, 307MB for a node_modules folder isn't actually so big that Git can't handle it. People get very frightened about this, but Git's performance on text files is pretty good. Obviously 307MB isn't ideal, but I strongly suspect in most cases you could commit those files in a single `initial commit` at the start of your project, and it would be fine -- you would not notice a major performance difference from Git.

The bigger concern is whether there are dependencies in creat-react-app that require node-gyp. Last time I checked, it wasn't bundling `node-sass` by default, but maybe that's changed. So there's a little bit of digging into your dependencies that you need to worry about to figure out what's going on.

I'm not going to say that `create-react-app` shouldn't be used. But I don't think `create-react-app` absolves you from needing to look at your dependencies and understand them. If you're in a position where you feel like you can't do that, then Git's performance probably shouldn't be your first concern.

What seperates psychological warfare from marketing?

If you pay attention to advertising for a week, you will be marginally educated on what the advertiser wants you to know about their products and services; this has some economic utility as you cannot buy what you don't know exists.

If you pay attention to psychological warfare for a week, first off you at bare minimum will not be happy or content as you are not buying if you are content or happy; they must torture you through mechanisms of persuation and manipulation in order to manufacture a desire. Once that is done, then they try to train you to have desirable habits to them; as a famous example McDonalds happy meals for kids creating obese adult customers 30 years later. If the food didn't have a serious downside (didn't literally injure you and make you depressed) you wouldn't come back to the restaraunt later for your momentary allevation of that depression\for a fix.

Now, Go try to find reliable information on Coronavirus. Which one of those is going on 99% of the time? The sales funnel is really training you to be the product for them.

The web is funded by marketers who engage in pyschological warfare for profit, no feature they will ever impliment is designed to make you happy, and technologists have tremendous profit motive to make up all sorts of excuses as to why this behaivour is acceptable when clearly it is destructive to both themselves and the web.

Browsers today are trying to become an operarting system so they have absolute conrtrol over the user experience and as they do that they are on a slow march towards building an unbelievably bloated application who's philosophy is to confuse, distract, and screw you at every turn all while managing your perception.

Case in point, it would take hours for me to research how to turn off all of those features as I don't need them and there's no mechanism in Firefox or Chrome to backup settings which those browsers reset randomly and intentionally.

So call these things what they are; at best, bloat, at worst, a stock pump and dump scheme combined with a tremendous waste of time.
They cannot practice, as in they cannot stamp drawings, or in other words take responsibility for things that require an engineer to take responsibility for. What it means in practice is that either they work in a sector that does not require stamping drawings, or a P.Eng. has to review their work and stamp their drawings.
Companies should be most definitely punished for not being robust to black swans. You can't predict a particular black swan, but you can definitely predict that black swans happen regularly. There is a reason why options have the "volatility smile" -- the risk tails are fat!

Triage isn’t a cure
Providers don't bill Medicare rates to normal patients, so none of that is valid.

Providers in fact make a point that they lose a significant amount of money at Medicare rates and have to limit the number of Medicare/Medicaid patients they see as a result.

I can confirm that a "45 minute" (5 minutes with nurse taking vitals, 25 minutes waiting in office exam room, 15 minutes with doctor) specialist "new" office visit was just billed to me for $246. They didn't charge me half the rate they charge a heart attack, they charge the heart attack patient 100x as much.

I don't think you understand how US billing works. Probably not from the US, or probably not subject to the system due to age (child or senior) or privilege (an engineer on a cadillac PPO plan perhaps).

Anyone who has ever experienced the US system knows that's absolutely normal.

Absolutely not. I gues I'm one of those weirdos that want privacy and to be able to pay the money that I earned for things without being tracked.

They re-coup this by overcharging businesses as well as having some VERY valuable data. I don't want to play the stupid credit card game either and try to guess which card I should get to get the most "deals".

All I want is a convenient way to pay that doesn't invade privacy. The only two payment methods that satisfy this that I know of are cash and cryptocurrency. I'm not a fan of cryptocurrency for many reasons so cash is my only option.

I can accept viewpoint only if we ALSO allow all unprepared companies to fail. This will then inform the next generation of CEOs to prepare more. If we socialize losses while privatizing gains we create wrong incentives.

I think the general sentiment is that we cannot just organically let most companies fail, so we are forced to bail out. But if we are breaking capitalism by bailing companies out, we should at least try to incetivize them to learn from mistakes rather than learn that they can do whatever when the times are good and get bailed out when the times are bad.
All the loyalty programs here (California) will let you provide a phone number rather than carrying a card. You should be able to use e.g. 867-5309 if you're really looking for anonymity.

There's something here with respect to chip / wafer fabrication, and the nature of holograms...

In the future, I am hoping that there will be a scientific theory which links completed (and functional) silicon wafers / chips / IC's -- with holograms.

In other words, don't look at the completed silicon IC as a series of masks, etchings, and deposition and removal chemical processes, but rather as something which could be formed holographically, where the results of the above processes create what is, in effect, a hologram, and this hologram is conversely a fully functional IC...

It sounds crazy...

But that's what my intuition tells me...

In the future (perhaps the far future), I'm hoping that there will be a way to generate IC's via a single holographic process, rather than multiple lithographic/mask/etch/deposition/removal chemical ones...

In a hyperconnected world, people with certain psychological Traits and Needs are going to keep causing a lot of unintended consequences.

Their behavior gets amplified. Especially if they have a lot of energy and are well networked.

And its not just the rich. You can find certain combos up and down the social food chain. Its like watching radioactive material going critical and starting chain reactions.

Where this is useful to society and where its dangerous, can these days be mapped out with much more sophistication, since we have everyones behavior history and psyc profile.

Maybe like in sports, where we understand what trait combos are needed for offense, defense etc and when things need to change up, we seriously need something like that. Right now its just mass madness with bad combos getting deployed at the 'wrong' time, in the 'wrong' situations etc...

Please elaborate.
It's worth to take a look at Karl Marx again. I'm not referring to any existed entities, but the model of pure capitalism is so problematic as he pointed out.

The usual reason against shutdown is because people have mouths to feed, mortgages to pay. But seriously, most of the products and services people are selling not really important or even any useful - that's why people have to advertise them so hard - it's not as straightforward as advertising cars, houses, and Coke. But those jobs are very important to those individual employees because it's their only source of income if their business were shut down, they wouldn't have roofs over their heads.

So the capital is the way to let people claim their part of the economy. It's so vulnerable that it's not even doomsday yet and people start to lose their source of income, and even without shutting down things. If we're going to shut down non-mandatory industries, people from those industries would get broke immediately - it's so deeply coupled so effective measures could not be taken.

In a perfect world, less than 10% of people working, or everyone working one day per week could feed everyone effectively. As automation goes on, the percent could keep shrinking. As a comparison, at the end of the day of a capitalist world, most of the "meaningful" jobs would done by very few persons because of the automation, and the rest of the world can only earn money at their mercy by doing "barely meaningful" jobs. Other than that, those who can't even get "barely meaningful" jobs have to working hard on futuristic versions of TikTok trying to become superstars - it's their only way of claiming their part of the economy.

Furthermore, the well-connected people get tested first as Trump suggested (or naturally happens in the US) is also a capitalist way of doing things. If we take Asian countries as an example, the testing kit is soon promoted as strategic resource mostly instructed by the government, which should eventually come from health care institutions, they have ideas to allocate those test kits in order to make maximum use of it, instead of blindly testing people back and forth.

If Karl Marx is not for you, it's always worth taking a look at Singapore where they did most things correctly most of the time. It's perfectly balanced in economics, politics and many, many other aspects (Though usually bashed by Western media as an authoritarian country). People can afford to buy houses, education is excellent and at a reasonable price, eating outside is cheap and easy, health care is affordable, and people are relatively free. Everything is carefully planned and designed by the government.

As a comparison, at a first glance, Hong Kong seems to be similar to Singapore to those people who haven't been there, but Hong Kong is a more western-style democratic society compared to its neighbors (at before 97 if you protest). But the rent is out of control, things are messier, there's no specific plan for things.

Again, I'm not evangelizing communism but those problems Karl pointed out have been overlooked largely nowadays.
To me, forgoing your own CEO pay exudes privilege. Instead, fight tooth and nail for your workers first and foremost.
