As mentioned in the paragraph above it, the chapter is a review, i.e. it's trying to quickly refresh the reader's memory on things they're already supposed to know; it's not trying to teach something new. So the sentence (“The set R of real numbers has two operations +: R × R → R (addition) and ∗: R × R → R (multiplication) satisfying properties that make R into an abelian group under +, and R − {0} = R∗ into an abelian group under ∗”) seems fine for that purpose.

If you look at any of the later chapters that are trying to teach something new, they are much more gentle and motivate the topic of that chapter: see e.g. “24.1 Affine Spaces” on page 759, or “26.1 Why Projective Spaces?” on page 823, etc.

Other chapters that are meant as a review are similarly terse and quick to the point (like Chapter 2), e.g. Chapter 37 “Topology” on page 1287.

I think it's good when books make conscious choices about what they're teaching versus assuming as a prerequisite (and communicate it to the reader, by using terms like “reviewed” — presumably the yet-to-be-written Introduction chapter will also mention this more explicitly).
> it's a enantiomer of ketamine, it's literally 50% of the molecules in ketamine

I’m not a biologist or a chemist. Why does this imply the chemical is as safe? What is the benefit? It seems like a blatant patent grab to bypass the low profit margins of ketamine. Is there evidence otherwise?

These are not the only ones doing stuff like this: I've met a guy with a huge, blue Van (older Mercedes Sprinter?), charging his car at an IKEA in Germany. The ICE was removed and he could go 200km on battery; this was done by a shop/company which do this on a bigger scale for that specific car model (hence he did not have to get a custom certificate for the car, which costs easily as much as a new car).
This comment (not my comment) on the verge says it all:

> Alternatively you could spend these THOUSANDS of dollars on a REAL BIKE. A real bike even allows you to get to places too!

> As a cycling fan, I cannot personally understand why ANYBODY would buy this product. You could buy a very decent road bike PLUS a basic turbo trainer (for indoor training if you’re really so bothered about that) for less than the cost of this dumb exercise bike. Or you could buy a very decent road bike plus a basic exercise bike, if you’d rather do that. Either of those two combinations is less than the cost of this dumb overpriced live-streaming exercise bike.

> You could even get a gym membership and take spin classes if you really want an instructor. My gym membership costs $27 a month and spin classes are free. So that means I could pay for the gym for SEVEN YEARS for the cost of this bike. Oh wait, and you’ve got to pay the subscription for this exercise bike too, at $39 a month. The bike plus two years of the subscription costs the same amount as nearly TEN YEARS of my gym membership. And the gym has weights too. And all the free spin classes I could want.

> Why do people spend money on overpriced gimmicks? I guess I’ll never know. Personally I would recommend getting a real bike. Cycling is great, you get to see the outdoors, you can ride with your buddies which is sociable (rather than being cooped up in your home, staring at some stranger who is paid to fake happiness), you get to visit new places, etc. And you cannot recreate proper cycling on any form of exercise bike. Bike handling, moving the bike side to side when you’re climbing up a hill, etc. If you really want to take part in classes though, get a gym membership and go do spin classes there. You’ll meet real life people! Yes, real people! And for significantly less money!

And this way you won't know if your page is AMP, or just a webpage (since amp follows www in things they are hiding).

I strongly suspect that this (and the eventual goal of making the whole web hosted by Google) is actually the rationale behind the decision.

Previous discussion: https://news.ycombinator.com/item?id=17927972

Also, training the user to treat the URL as text, so that you search for domains (type "amazon" instead of "amazon.com"), is better for them. The "URL" bar is for Chrome also a search bar (and every domain you enter is sent to Google "for search suggestions").
Having your ear wax not removed quickly will not cause permanent tinnitus, that's ridiculous. If tinnitus is caused by ear wax it will be gone after removal.

It is the removal process that can cause permanent tinnitus[1], like ear irrigation done incorrectly, which would be your doctor's fault.

I have 2 different permanent tinnitus caused by improper ear irrigation (one by a nurse and one by myself), one is low freq thumping and one is like crickets. I use some kind of ear wax softener daily hoping I won't develop blockages again and risk more tinnitus.

I think the trouble is that the devices are getting too good and there is really only incremental improvement every year so the upgrade cycle is getting longer.

I typically get the latest phone every year (but it starts to feel unnecessary) - iPad's and Mac's, however, last a lot longer (several years) for me these days.

I wonder where the real innovation is going to come from? AI, AR?

> Uses only modern cryptography, with formally verified implementations.

That's a bit light on details. Does it have hardware acceleration? Replay attack protection? Perfect forward secrecy? What are the underlying algorithms? Implementation verified by whom?

> Small (~25 KB), with an equally small and readable code base. No external dependencies.

This looks cool, however I don't like the fact that it doesn't use a trusted crypto library such as libsodium. It is likely to get less review and if weaknesses are detected in the algorithms, it is less likely to be improved.
I chose to study mathematics in university precisely because of the second reason: logical thinking. By extension that includes the ability to write proofs. Even if you aren't actually writing proofs on the job, getting into proof-writing mode will make your technical exposition much better.

Isn’t this how things usually work?

* New stuff comes out -> niche

* Some smart people want to simplify it, but theres too “magic”, and fades away

* General public learns about the underlying tech or at least structure

* Big adoption happens as people trust it

* Some people want to make it “magic”/simple again, but therefore creating a black box
Forward a few years, and the industry seems inaccessible for a long time

* people figure out again how things work

Medical, construction, tech, space, movies.. almost everything has this pattern
If you have to do make clean in a monorepo you are pretty much toast. Tooling for impact detection and reliable makefiles that always succeed incremental builds is absolutely crucial.

In a way this is one of the hallmarks of a monorepo - Interfaces and dependencies changing so quickly it becomes too troublesome for humans to categorize (and re-categorize) them into repositories, so you let a machine (makefiles) do the work instead. And even without a monorepo you still have the same problem, eventually you will have to integrate all your mini repos into one final product, which you want to have tested. This is something you want to do as frequently as possible, ideally on every commit, not by doing major version-steps of sub-projects.
"get out of you don't like it"

Nobody saying this has actually researched it. Too many people in the states are under the impression you can just up and move to a European country, no problem. One friendly-but-clueless acquaintance got flown back from Heathrow for asking the immigration officer about where to find jobs when she landed.

If you don't/can't:

* work in tech or medicine

* go to university in Europe in a high-demand field

* woo a European to marry you (a favoured option among women I knew in college, I notice - wonder why the gender disparity?)

your options are pretty limited. There's the Dutch American Friendship Treaty and digging through the family bible for the birth cert of some Irish or Italian grandparent and that's about it.
Yes these "improvements" in Chrome are meant to make google the defacto interface for using the web.

Imagine a world where 99% of users do not have any concept of URLs or any other fundamental WWW concepts. Instead, they open Chrome type whatever they want and get the results. It is not difficult to imagine a world where the non-tech users do not think of google as search engine but as internet in itself.

Netflix tests tracking your ‘physical activity’ to improve video quality
Yes, I thought about possible reasons why it might be meaningless to ask the question. (Maybe gonational already has billions invested in green tech, or maybe they consider Apple a more responsible GHG emitter than any of the other phone manufacturers even if he/she buys a phone for $400 and plants trees for $600.)

But I was interested in his/her reasons.
The short answer is it can be both (ie safe, beneficial and effectively a patent grab). It is also unlikely that an enantiopure chemical is less safe then it’s racemic counterpart and not unlikely that it is beneficial (this is not without precedent... this is also chemistry 101 and I don’t feel this is the forum for it)...

The doubt is not so much the safety but is the benefit of the enantiopure version worth the cost.
There's also udp2raw-tunnel: https://github.com/wangyu-/udp2raw-tunnel

It allows you to tunnel UDP over a fake, non-lossless TCP connection. That is, it wraps packets in TCP headers to make them look like TCP to firewalls, but it doesn't actually implement TCP; instead, each "TCP" packet corresponds to one UDP packet, and it makes no attempt to resend dropped packets. This way you avoid the problems with TCP-over-TCP.
The whistle noise started two days before cleaning it. After cleaning it started getting worse. Nowadays, it's variable. It goes up and down irregularly.
There's definitely a readjustment period where your brain tries to reach homeostasis again, which can lead to depressive episodes. But it's important to remember these people were likely morbidly depressed to begin with, and taking ketamine trials was an act of desperation.
Natural Vitiligo Treatment System Review
Most people do not suffer from oily skin until puberty. Why. Our endocrine system usually does not start to manufacture the hormones responsible increased sebum production until puberty. Even after puberty, hormone fluctuation affects our sebaceous glands. Women may notice that their skin will fluctuate during their cycle because of the changing hormone levels. Birth control pills or pregnancy also affect hormonal levels for similar reasons.

Genetics influences almost every aspect of our lives. Nearly all of our physical traits, from stature, to intellect, and even our skin are partially controlled by our genes. It is an unfortunate truth that some of us will just be more likely to have oily skin due to genetics. So, if you find that your mother or father has shiny skin in old family photos, you are probably also predisposed to oily skin.

The certificate itself tells you nothing about who paid for it - it doesn't even tell you which email account was used to confirm some level of association with the unrelatedcompany.TLD domain.

My biological grandfather (long story) is considered poor in the US, and is at the very bottom of the social hierarchy (you know, early 70 hippies that got stuck in the past?).

Yet he lives way better than at least half the US population imo, and would never trade his place with the other half. He live in a cabin in West Virginia, share 100 acres with two other people, have access to a natural gaz well for 100$ a year (shared with 4 other people). Free food, almost free gaz, free beer, and he make 20 to 50 bucks a month from playing banjo at local jam/bars. Well, winter sucks up there in the hills, but still. I think that the most he have worked in a year was 3 month doing odd construction jobs (I think the town name was Akron).

Being poor doesn't suck because you're poor, it sucks because you don't live well enough and you can't really enjoy life. If you're poor but live well enough, it doesn't really matter.

A lot of chemicals are "50%" of each other but completely different. That's not how chemistry works.

Water is H₂0. Hydrogen peroxide is H₂0₂. I wouldn't substitute one for the other.
What your casual elitism disregards is that people who actually do the work can have different ideas, especially related to the work they are doing. Put another way, since they have a different perspective than the higher-ups, they are sometimes able to find potential efficiencies and product improvements that wouldn't occur to others.

Additionally, front-line workers can see real problems with how customers experience the product that may not be reflected in the metrics used to evaluate the product, since metrics
are inevitably gamed.

The ratio of good to bad ideas doesn't matter if you miss the one good idea you really needed. A company that invests in ways to effectively use the ideas of 'untrained people', as you so delicately put it, can derive a lot of value from those ideas.

I'm not that optimistic. Technical literacy tends to peak with literate/interested users who saw the rise of a technical medium. (E.g., I guess, my grandfather knew more about the intrinsics of a radio, even if I try to educate myself watching tube radio repair videos. High frequency stuff was generally sorted out, before I was born. I'm a high frequency native, but not necessarily an expert.) As things start to become more complex and tend to be more tightly integrated at the same time, the underlying technology somewhat vanishes. If you are faced with this as a fait accompli, it isn't natural anymore to investigate what is ultimately an opaque module.
However, this opaque module is our universal means of production, communication and creativity. We may have to counteract what may be a tendency towards simplification and taking things for granted.

I'm no supporter of the current federal government, leader or cabinet.

But these points have little relevance.

Public drunkenness laws are a state matter, nothing to do with the federal government, have been in place effectively forever, and these days are only ever enforced against people who are being violent or damaging property. They're hardly controversial.

(If you're talking about recent NSW lockout laws, I can agree these are stupid, but they have been implemented and applied as they were designed).

Your attack on the prime minister is grounded in religion, which is not cool.

The robo-debt collection scheme was obviously poorly implemented, but was part of an effort that began several years ago to use technology to make government more efficient. It has since been reviewed and reformed, a process that continues.

Regardless of which political party you prefer, or even which system of governance you prefer, governing is always a case of managing trade-offs and competing virtues, and can only ever be an effort to achieve the least-worst outcome, never an outcome that pleases everyone.

Throughout the world and throughout history, seeking efficiency and fairness in the taxation and welfare systems is about the most difficult thing governments have to do.

None of this means the tax laws under discussion can't be drafted in such a way that they accommodate the thing you're talking about.
