It's really hard to say what the carrying capacity is, because unlike other species, humans keep modifying their environment. Without clothing, the answer is probably a few million. Without agriculture, the number is south of half a billion. With mechanized agriculture, large-scale land use changes, and artificial fertilizer, we can probably still double our current population. But at the cost of stressing the rest of the environment. I'd guess the "safe" level is somewhere in the low billions, i.e. 1-5 billion.

I was mainly talking about the SF case, where lower global population should make it more affordable rather than causing things to be abandoned. This is what is playing out in Tokyo, which is still growing while the countryside is abandoned. As for the small towns, it sucks, but dying small towns has been a thing for quite a while now as agriculture has become more mechanized. Detroit's kind of the odd man out being a depopulating metropolis, so I'd actually argue that it's a terrible example, at least for the next 100 years.
When you say your children are the reason you stay on treatment, would you go off treatment if you didn't have kids? What about treatment makes you want to get off of it?
Pros: for even the worst startup there are fewer useless people, bureaucrats and insane witch hunt types than there are in a large business. You learn more if you're a go-getter and your work can really make a difference.

Cons: your returns are way more volatile -CAPM adjusted, I'm pretty sure it's not worth it, and if you're trying to learn things and need formal mentoring rather than 'self serve' you won't get it.

I can't stand bureaucracy and non-contributors with power over my life, so I prefer small startups.

Your proposed enumeration of decimals (counter-intuitively) would miss an uncountably infinite number of values. This enumeration is not possible in any fashion, which you can prove fairly easily with Cantor's Diagonal Argument[1].

The punch-line is that there are more real numbers between 0 and 1 than there are whole numbers greater than 0. The proof basically shows that even if you imagine that you had a countably-infinitely-long list of all the real numbers between 0 and 1, you can construct a number that must be missing from the list -- which is a contradiction, and thus no such list can exist (implying that there are more numbers between 0 and 1 than numbers greater than 0).

For instance, your enumeration is missing every irrational (or even recurring decimal) number. That set of numbers is uncountably infinite.

And yet don't many European countries deny other genocides (or refuse to call them genocides) for political reasons? At the very least the law should be fairly applied to genocides.
It may have been less oppressing but it was still oppression. Also I'd argue that they _thought_ it would be better, not that it was. We don't have perfect information to make rational choices and they certainly didn't have it back before a global communications system existed. The factory owners routinely lied and changed the deal on employees.

Regardless you stated that none of the opression that happened in Europe to workers happened in the US and that is probably false. If you had a source for that quote from Marx, I would like to see it
Where do people get this from? Their filings clearly state they spend millions a quarter on marketing.

Not necessarily. Could be a function of the need to scale very quickly, which invariably allows some mediocre people to slip in. A 9% cut sounds reasonable given how fast and how much Tesla needed to scale up in the first place.
> We don't actually have school lunches

And this is the real kicker. Norway is a relatively affluent country with a comprehensive social safety net and a relatively homogenous culture.

Here in the US, we have too many children living in poverty, often with single parents and broken families, who would never bring their own lunchbox in the first place. School lunch is a necessity, otherwise a lot of kids would go hungry and not be able to learn anything.

Norway also doesn't have a huge domestic agriculture sector with outsized political power, and school lunch is a really nice subsidy for them as well.

Responding solely to the 'moat' question: think railroad price wars in the late 1800s in the US.

Industries with capital expenses relatively large compared to contribution margin tend towards local monopolies. When faced with a potential new entrant the incumbent can lower prices to where the entrant's assets can't return their cost of capital. The incumbent's capital is already sunk so they can afford to bring prices close to the marginal cost of providing the service. This threat of a price war is usually enough to deter entry.

This also leads to agglomeration in local markets both to avoid duplicative assets and to add credence to the price war threat.
In the white paper it's literally called the "timestamp server" and that is its sole function. Timestamping transactions in a decentralized environment.
Yeah that's an interesting perspective. There are a lot of security issues that come into play when we start toying with how the Web platform works, and I'm somewhat curious whether all Websites should have a sort of "uninstalled" versus "installed" mode, where the uninstalled mode is basically able to do nothing. Then users have to go through an "install" flow to enable the riskier APIs.

I think one other area that the Web hasn't tapped into enough is using protocol/scheme identifiers to introduce strong guarantees to URLs. You can compose schemes with a '+', so I think if you wanted an "on click guarantee" that a site is going to have certain security properties, you might try something like:

http+safe://.../
dat+safe://.../

And then the site would load in a "safe mode" which, like the "uninstalled" mode, is extremely limited in what it can do.
That's definitely true. I hike pretty regularly, I went hiking here just a few days ago:

https://tinyurl.com/yd58grex

However, you can really only do that between april and november here. There's four months of the year where going on any meaningful hike is absolutely only for people who are totally dedicated and have thousands of dollars of gear, plenty of experience and have been guided on that specific track during winter at least once. Those are the same four months when there's no sunlight and the seasonal depression sets in. I'm not in that league and I'm not embarrassed about it.

The whole "just exercise, it's great and easy" shtick is kinda naive and TBH vaguely annoying. Lots of people, even quite wealthy people, live in circumstances where it's actually just not easy, at least not all the time, and exercise kinda only works for mental health if it's regular. You should see the tires on the bikes that the cyclists who try to keep form during the winter here have to use just on city pavements.
Yea, I just abandoned the thread altogether at this point. Might even be Tesla shills - don't know

>What happens when someone riding one of these gets killed by a driver?

Probably the same way they normally are. It depends on the circumstances. Generally speaking the rules that govern traffic flow have a bunch of redundancy and whoever violated more of them is at fault regardless of mode of transportation, liability depends on state law, human factors (how "sympathetic" is the victim is the big one), etc.

Generally speaking the system works fine unless you consider the normal bickering over who's at fault to be not fine (the same bickering you get when both parties have the same mode of transportation).
I think it's a cargo cult problem. We see massive companies showing off their solutions to gigantic engineering problems that can only be solved in a certain way, and we think that we also must solve problems that way. Or that we'll get promoted if we solve problems "like <insert-big-name-tech-company>" in our architecture.

Chances are, all you need is to properly use a relational database or another similar, proven, highly flexible and optimized tools, and you'll be fine until you have the time and money to solve the scale issues.
I'm the same as you (one or two meals a day) but I don't think we can generalize our experiences to a recommendation (especially across gender lines).

My partner gets impossible really quickly if she doesn't eat about four times daily, and I've met enough hangry-type people to believe that some people really do have to snack. Although I guess I'd encourage everyone to try not-snacking given how much more convenient and healthy it is if your metabolism can manage it.

Couple of trivial ones with good results:

Noted down the websites that I visit when I am waiting for something to finish, selected the ones I don't really need and blocked them. That reduced the context switching significantly.

Yes a thousand times. I use Blender in a professional setting, and the way it works is you set your software up and you do not touch it in the middle of a production if you can help it at all. No upgrades to newer versions, and certainly you don't use webapps. The risk of something breaking to new bugs, backward incompatiblity or hosting unavailability is unacceptable.

Hi everyone! I made this site in my spare time between job interviews, and it's grown into a community of ~50 people, many of whom are talented pixel artists. Since it's kind of novel and weird, I thought you guys would want to know about it!
Certain contexts DO allow Laymen authority to determine the legality of things. Juries and voting come immediately to mind.

Conversationally, saying "I think this is illegal" instead of "this is illegal" freely surrenders to those who disagree with you to use appeals to authority to bypass conversation without addressing what you said. I think this is a bad strategy if you're levying a case in the e-court of e-opinions.

Just reading the first few comments.... I really don't get the Tesla hate. Is it hacker-ish contrarianism? Have they done something? What's the deal HN, why are we cheering against the home team?

Overall Musk has been pretty straightforward and explicit with what he's doing.

Tesla (and spacex) set extremely ambitious goals, like none of their competitors do. They take big risks. They're not interested in reducing risk. They're interested in a business plan that leads to a mass migration of icbs to electric (or humans to mars). The nature of ambitious goals is that sometimes you don't hit your marks. The nature of risk taking is that you might fail, and have to do fast paced adjustments to recover.

Riskiness also means (literally) that Tesla comes with some chance of total failure. If they lose two or three big bets in a row, it could be game over. There are no cash cows or guaranteed income streams. Tesla is not Toyota or Microsoft. If you own Tesla, you need to be ok with that risk. Don't like it? Perfectly reasonable. Sell.

Personally (not an investor or customer), I think these companies are awesome. If GM disappeared tomorrow, nothing that I care about changes. If Tesla disappears, this could set back electric cars by 5yrs. If McDonald Douglass rocketry disappears, someone else will launch rockets for the US military. SpaceX... that hurts our chances of landing people on the other worlds anytime soon.

None of this risk profile stuff would even be controversial if Tesla was a fund. A fund manager can be as risky as she likes, provided that's the stated investment goal. Why doesn't Elon get this amount of rope? .. at least on hacker news?

Seriously, what has he done to deserve this negativity?

Hey I’m right there with you, and sorry if I misread your comment. I strongly advocate for a voluntary solution to the missing social floor through the use of collectives and total automation of basic human needs. I don’t think taxation is a good long term solution because it’s inherently not voluntary and thus will always cause tension.
A clinic, concert, or house party are all terrible settings for taking LSD. They are confined, crowded spaces. You want something wide open, in nature. Try the mountains, or the desert.
In general, "at will" employees don't have anything to negotiate. It's strictly take it or leave it. There are no contracts unless the CEO gets involved, and the CEO won't be getting involved just for you. The hiring manager will just pass on you and move to the next-best candidate.

You negotiate your starting salary, and that's it. So make sure you account for the likelihood that you will get zero notice and zero severance when you get fired. Which is to say you need to ask for more money, and save some of it in high-liquidity, low-risk form.

People wonder about salary inflation, but when you look at total compensation, it isn't quite so extreme. Companies cut or eliminate benefits, and employees have to demand higher salary to compensate. The salaries are going up at a higher than usual rate, because companies are slashing benefits packages faster than usual.

Those companies are figuring out the hard way that employees are not clueless about the value of their benefits. New employee candidates coming in will see the crap benefits and ask for more money. Existing employees will leave for either benefits more similar to what they once had, or for more money. In general, cutting the benefits results in being less competitive overall as an employer, because it usually costs less for a company to buy the benefits in bulk, than for employees to buy them piecemeal.

In the case of severance, the major advantage for the company doing it is that you absolutely cannot spend that money on anything else until you are fired. You could get that by buying a special insurance policy for unplanned unemployment, or you can discipline yourself to never touch your "severance fund" except in dire emergency. Also, you are taxed on a severance payment in a year when you otherwise have less income, because you got fired, whereas a personal "severance fund" is taxed as you earn the principal, and again when you liquidate, if you realized gains. Make sure the company will be paying for all that before you start work, because once you start, most of your leverage disappears. They no longer need to convince you to quit your previous job, and only need to do just enough to keep you from quitting your new one.

The last severance I got was in 2002. No company since has ever been willing to pay it out or even negotiate the possibility. Severance is dead. Long live the personal "oh shit" fund. Make your employer pay you enough to have one, along with a personal retirement fund, a personal vacation fund, a personal health care fund, a personal commuting budget, and personal equivalents of all those other things that many companies once paid for, but no longer do.

We don't need a union, if everybody can individually commit to asking for more money.
This is partly YCs fault because they basically groom startups and usher them into the maw of VCs while glorifying the exploitative VC model

I believe this is a part of culture that VCs are creating. I've been interviewing lately and I've noticed certain personality traits among YC founders that I'll call "Business Sheldon." I saw it a bit 5 years ago when I went to Startup School, but it's pretty pervasive now, so much so that I see it as a red flag. If you've seen the latest season of Silicon Valley, the character that Dan Mintz played touches upon this: https://www.youtube.com/watch?v=fzbwLktN60c
That's reflection not generics. It's mostly the same denotational semantics, but much less efficient performance.

That our brains are more complex that hydrogen atom is a fact, but that does not invalidate scientific method. It simply means that we need much more time, more research, more data and more complex theories to understand brain than we need for an atom.

No? Generics are type-checked at compile time.
Well, then why does it even matter that it's hosted on GitHub? If GitHub is being used as little more than a public hosting page that people will directly link to, then what benefit is there from being on GitLab?

To be more specific about what I was saying earlier: the differences in form factor, features, layout, etc. are all going to be unfamiliar to those who don't know GitLab--so, presenting them a migration guide to GitLab from GitHub that's also already hosted on GitHub, with the layout and all the features they're already familiar with, is going to have a higher conversion factor than otherwise. It's not necessary that they randomly browse to this guide. Guides work because there's a smooth transition between the easy/familiar and the objective. By starting on the familiar, the guide is more inviting to follow.
And yet here we are discussing a blockchain start up putting almost zero effort into verifying the provenance of a piece of art despite verifying the provenance of art being its entire business model. Or are we just going to Scotsman them into non-technical shouting?

a hypertext driven way of fetching the data.
It good to see a focus on weightlifting, and I'm glad to see that research like this is proving the same sort of benefit. It seems as though it's kind of faux pas to focus on strength when other options like cardio are available. The standard for physical excellence these days has become the marathon, triathlon, or iron man, where I think that a long term focus on strength training is it's own unique reward, and it's own unique challenge, taking years and years of hard work and focused dedication to achieve peak performance, as opposed to a marathon where (a quick google says) one can achieve with 20 weeks of training.
It's a PR fluff piece.
Not smoking doesn't mean you won't get lung cancer. Eating enough fiber doesn't mean you won't get heart disease. Are you seriously suggesting that the intent of this article was to say that lifting weights will make all your problems go away?
Can you deploy a email or dns server/client on this or is it only for http servers !?
No, you have to use reflection to determine the type at runtime. Generics use the compiler to prove the type at compile time so that the runtime can forego the much-slower reflective code paths.
AdBlue is usually made from natural gas, so one has to figure the CO2 it takes into it. It should be able to use less diesel fuel, but I don't know if the reduction there is worth the increase in AdBlue use. The hotter the engine burns, which in this case should mean the higher the compression/inlet pressure is, the higher the efficiency, as well as the NOx levels generated. The impact of particle filters on engine efficiency is not know to me.
i'm of the opinion that the psychotic breaks risk would be an engineering problem to overcome in the context of using psychedelics therapeutically.

besides, in a clinical context, it's highly unlikely any kind of psychotic break could get too far out of hand; an astute clinician would recognize the patient spiraling out of their control and administer a correcting dose of an anxiolytic, or, failing that, a trip-ender like an antipsychotic.

Exactly this. This is really one gigantic wealth transfer from the USA to a few semi-Chinese entities, btw.

The 27 year old American accountant who desires to quit his desk job will send $4,000 of his salary (or more) to buy some Chinese-made machines. The 200 or so major shareholders of Bitmain profit instantly.

The accountant barely profits on his transaction. [1]

[1] some will profit more than others depending on length of time holding assets, but statistically someone ultimately holds the bag.
I would be skeptical of new entrants to scooter / bike sharing. In China, ofo and mobike together captured about 95% of the market. If it were possible to challenge the companies that have reached scale, one would think one of the many dozens of failing competitors in China would have figured out it by now.
