At least with flossing, regardless of whether there are double-blinded controlled studies for it, it makes my mouth feel much cleaner when I do it, I can see a lot of plaque coming out when I floss, and there certainly doesn't seem to be any evidence against it.

With twice yearly dental X-rays, though, even though the doses are really small, all X-rays carry a risk of cancer, so it seems close to malpractice to request these X-rays without evidence to back it up. Try refusing X-rays at your dentist's office because you've done your own research, though, and they look at you with the "Oh I bet you don't vaccinate your kids either" look.

While obviously some are mentally unstable, and that's what drives them to the streets, what's being ignored in this conversation is that being on the streets drives many to mental instability.

Being homeless makes it difficult to find safely and sleep. Even a few days of that condition is extremely mentally taxing. Months or years? It's no surprise that so many of the homeless we see have mental issues. No surprise at all.
Nice job, this would have been nice to read through when i first started OpenCV.
I've been programming since I was a teenager, and for a long time I found myself struggling with my syntax and edge cases. Once I started using python, about 10 years ago, programming quickly turned into "what's the best way to solve this problem", instead of "wtf do you mean null pointer".

In Eastern Europe it's often the case. Worth mentioning however that plumbing services are much cheaper then in States, and there are usually no legal/insurance nuances which reapairing may bring in the US. So it's simply easier to call a plumber and have trouble solved then include a landlord into equation. Broken washing machine, or expensive furniture in most cases are on landlord, though.

I wish Qualcomm took all that legal revenue and converted it into a fab. They are basically limiting their upside now. Patent licensing for wireless standards has to be "fair". If the LTE/5g patents were open, they could charge the max possible amount for a fully integrated arm + modem core optimized down to the material science.
> It seems like despite a lack of evidence, it would be very hard to ethically approve a randomised trial of teeth brushing over a long period.

This is the exact same argument that was used to evade studying the effects of low doses of aspirin on heart disease. Everyone “knew” it worked, so it was thought to be unethical to put people at risk of heart disease into a control group. Many millions of people spent money for years to consume a constant supply of aspirin.

When the question was finally studied, it all turned out to be nonsense. In fact, it turned out to increase death rates from higher cancer risk. All that money could have been spent on actually improving health.

I think he means to say that the descriptions are automatically taken from wikipedia and unsurprisingly the two descriptions have not been written in exactly the same way. Shame on wikipedia, shame!

No because I would ask myself “Is this a description of why the end state of the code needs to be this way?” to which the answer would be “no.”

I don’t think you’d add a comment like

Either. Its just too small a detail that it isn’t worth directing your reader’s attention to that.

My proposal isn’t a rule, but rather a question to ask yourself and then to exercise your best technical-communication judgement about.

I think it's easy to understand that even though you enjoy responding to calls about fixing a leak at 10pm on a Tuesday that not everyone would. And for many it would be a significant drawback to owning property.
anecdotal but i’ve visited third world countries where they don’t brush at all and some people had great teeth (others... nkt so much). not sure if it’s genetics or lack of sugary and acidic foods

I mean, it isn’t bad. Government policies are pushing people this way, even if most of the, still lack actual parking spots for their cars where they could charge at home. Honestly, I don’t know how they do it, 70% of the parking in Beijing is on street (usually illegally). Perhaps the Model S crowd can afford parking spots, which is why you don’t see a lot of BYD EVs that aren’t fleet.
That was my biggest concern as well. I am sure you do not do that, it it would have been so easy to funnel my data (or metadata) to your servers.

A measurement is an interaction that crosses the Heisenberg cut separating the quantum from the classical world. Eg you prepare an atom in a superposition of states relative to some 'quantization axis' determined by a Stern-Gerlach apparatus. The state will randomly 'collapse' into one of the available final states, resulting in a macroscopic dot on some screen. You and all your physicist buddies will agree on the placement of the dot.

There is no agreement on how this happens, complicated by the fact that there is no such thing as a classical world I alluded to above, ie any interactions with the apparatus and the conscious observers supposedly obey the laws of quantum mechanics.

Ask HN: Does legal team object if manager wants to send feedback for contractors
Hi HNer’s,

I work as a consultant/ contractor for a company. I asked my manager to provide feedback since appraisal cycle is going on. She said she needs to correspond with the legal team first since they keep on changing the rules all the time. Her response quite surprised me coz last year itself she had send kind words about me.

So my question to HNer’s is - is there really a system wherein legal team of the company decides if managers should send feedback/ testimonials for contractors?

Thanks in advance for any suggestion you could extend

I had dental insurance a couple years back and went to the dentist for a cleaning after probably 10 years and the dentist and the cleaning tech both said my teeth looked about like I skipped my last 6month visit (before I told them it had been a decade)

So how would do that with routers, which in the UK conveniently pass a copy to NSA of all communication, with phone baseband devices (qualcomm), with PC CPU's which all have mandatory "lawful" backdoors?

Arguably too much of a compromise. This is just Guido doing a "because I say so" and imposing his bias against functional programming. Give me a properly-designed language like Ruby any day over Python's bag of compromises.

Surely the twice-a-year teeth cleanings matter? In 2005, Evidence-Based Dentistry highlighted a systematic review on the effects of routine scaling and polishing (you call it teeth cleaning).

It very obviously works aesthetically, especially if you drink a lot of tea. I had no idea it was even supposed to have any health benefits besides the free check-up which some (my) dentists throw in.
Anecdotal evidence doesn’t have to have any of those qualities but I do think that’s exactly right, yet most decisions just won’t have a basis in controlled trials due to the variation in the patient group and because you just can’t have controlled trials for most things .

For example, implant placement at a 45 degree angle are totally weird mechanically speaking given that the biting force runs down but dentists may do them to recruit better quality bone because they know that implanting into low density bone or calcious mass will likely lead to an implant failing but they just don’t see much failure due to weird angles ... this particular case happens so often actually that some companies now recommend placement at 45 degrees.

Personally experience, conferences, etc . It’s not how the world ought to work but it is how it mostly does.
It's too bad there's not a company with enough funding and incentive to make equivalents that don't need to phone home. Ones that are competitive in price, functionality, etc.

Underwater Cities Boardgame
Bogus headline, article confirms basic beliefs are true:

> brushing with fluoride toothpaste that matters, not the brushing alone. Doing that doesn’t just prevent gingivitis and plaque formation; it also prevents cavities, which is the outcome that we care most about.

> powered toothbrushes reduce both plaque and gingivitis more than regular toothbrushes

> toothbrushing with flossing versus toothbrushing alone most likely reduced gingivitis, or inflammation of the gums

Article seems to miss that gingivitis is a bigger concern than cavities for adults
Wait, is that all? The safe limit is likely quite conservative, so 5x the annual safe limit in a year doesn't seem like a big deal.

> Reformers who seek to abolish tribalism usually find that they've simply redrawn the boundary lines and replaced one set of tribes with another.

Spot on. It's not always (or generally) under their control either; all it takes for someone else to start calling followers of a revolutionary by some name, and a group is born.

> group boundaries based upon choices or values are more useful than group boundaries based on origins or genetics

They're also much less likely to stay as groups for long. Immutable characteristics like skin color, origin (class and nation), culture, religion or even education (which is immutable in practice for most people past the point they need to become self-sufficient in life) make your membership in a group easy to verify, and out of your control. This makes these characteristics easier targets for people to wrap their identities around. You have to accept that you're $country-of-birth-an, but you don't have to accept being anti-vaxxer - you can leave that group the minute you don't feel like being in it.
Why would you want to "mediate conflict" with a group who isn't strong enough to be a significant threat to you? There are more than one way to resolve disagreements.
Slavoj Zizek vs. Jordan Peterson Debate
There are two walls. One wall has two slits, the other wall is where the particles/waves/balls/whatever colide and form the interference pattern (or not).

You don't need someone observing the second wall to get the interference patters. You can replace the person with a photographic plate, a CCD sensor of a camera, or other equipment. All off them are more precise, reliable and even cheaper than a graduate student with paper and pencil.

The problem is if you try to add some type of equipment to first wall to collect information about how the particles/waves/balls/whatever passed thru it. Whatever equipment you add it will disturb the flow and it will kill the interference pattern.

This is not a technological problem. It is how the universe work. If you propose to use some particular method (like using light to detect the balls) you will sooner or later find that there is something that gets broken (see the former comment).

An important detail is that if you use a macroscopic object like a basketball, the slits size and the slits separation must be tiny (less than a millionth of the size of the nucleus of an atom, probably much less). So you intuition about how thinks work in the macroscopic level is not a good guide to how thinks work in the microscopic level. In the macroscopic level you can approximate the basketball as a perfect classic solid. It's just an approximation, a very good approximation.
I like the black bar, it shows both mourning and respect.

Occasionally I'll see the black bar and the notice and not even know who the person was - at which point I get to find out about someone amazing I didn't know existed and to appreciate their contribution.

Obviously I'd prefer that there not need to be a black bar though.
In many cases, the cause of the problem may not be contractors.

There are lots of clients that clearly set their expectations for contractors who they see as expensive necessary evil: they want you to deliver fast and now, they do not want to hear that bubble that it will take longer to deliver a robust system.

One other possible dotcom connection, to the alleged decline in empathy...

Before the initial IPO gold rush, there seemed to be relatively more thoughtfulness and altruisim among CS people, about futures of this technology.

Then the norm became CS students (and sometimes professors) talking like MBA students (who, previously, were very different, and complementary). Talk of futures became simplistic, self-focused, and self-promoting, and often seemed disingenuous.

If we look at the way social media works today, one interpretation is that some dotcom founders have remade the world in their image.

("The Prophylactic Extraction of Third Molars: A Public Health Hazard")

I'm lucky like the author. 47. Zero cavities. Gums are healthy. Brushed infrequently as a kid and never flossed. Teeth were treated with fluoride by a dentist as a kid. Didn't start brushing daily till high school. Didn't start flossing daily till my thirties. Skipped going to the dentist at all for maybe 5 years in my mid-twenties. Typical western diet. Never had braces. Straight teeth.

Both parents, both sisters, and my brother all have several to many fillings.

No smokers.

I see my dentist twice a year but they only take x-rays every 18 months.
I agree. I’ve struggled with my teeth for years. Always hearing twice a day. But what I’ve learned is it does no good to wake up and brush your teeth and then have a coffee with sugar that sits on your teeth for several hours. I think one may need to brush many times a day depending on what you’re eating habits are. But I’ve also heard too much brushing can hurt as well so I still do a main brush morning and night but if I have something sugary or acidic I do a real quick brush. I truly believe for the best results you need to consider your teeth for the entire day and rinse them accordingly.
I do that, so I dont end up in SensorVault.

i live in shanghai and have ridden in many byd's, basically the compact car model is very popular for didi drivers which is the equivalent of uber/lyft here. I'm not 100% certain if that compact byd is 100% electric, but it seems to drive quiet. There are government incentives to buy electric cars, less tax, lower price, the license plate is also a lot cheaper. In shanghai a license plate costs 100k rmb (15k usd) and you have to compete with tens of thousands others in a lottery system to get the right to buy one in the first place, for electric cars it's less than 100 usd. Some workarounds are to purchase a license plate from out of shanghai, but that means you can't drive on the highways and expressways during rush hour traffic (7:00-10:30 and 15:00-20:00 mon-fri), if you're caught by any of the millions of cameras, that's a 3 point fine and 200 rmb (you get 11 points per year which means you need to retake drivers ed. And re-test).

The byd's i've ridden in seem ok, quite underpowered, but good for city driving, i don't know how good the mileage is for one charge, but it's comfortable to sit in for a small compact, never had an issues with it as a passenger. Then again, i would never buy one of these myself, it's about 280k rmb, this is for a domestic car, there are a lot of other choices at that cost point for foreign cars even.

I just test-drove a model x tesla today, much nicer, but not the same price point, about 790k rmb.

I think warren buffet or someone invested a lot in byd, they have an suv version, too.

Agree with much of the commentary here. Investment returns on real estate ownership (whether as primary residence or as income property) often ignore externalities and the time investment by the owner. Having the freedom to not worry about or arrange resolution of leaking toilets, gophers in the lawn, broken fences, etc is a great return on non-ownership!
In string theory, they use quantum (super)strings, not classic strings that somehow simulate quantum particles. It's quantum all the way down.

Accepting the results of mediating instructions doesn’t require empathy, it requires a deference to rules-based process and a commitment to be bound. To use the US as an example, our social empathy has never been higher, whereas our commitment to mediating institutions is at historic lows. (Especially to the highly empathetic left, our mediating institutions have become mere means to ends.)
