A climate scientist should be able to pretty simply explain why CO2 emissions are bad. They trap heat, which warms the planet. Unlike climate science, urban planning doesn't get much attention, so you'll have to forgive me for being ignorant of things which experts consider obvious.

For your divorce rate statistic, is that for any commute over 45 minutes, or is it specifically for car commutes? Because lots of dense cities with good public transportation still have long commutes.

This is why I asked what the reasons were. If they're things that don't apply to an autonomous car future, then we should welcome them. If they still apply, then autonomous cars won't solve the problem. When I see people complaining about sprawl, it's usually because of things that will go away in an autonomous car future. But that's not necessarily a comprehensive listing of the problems.

For some reason that effect was much more pronounced during this flight (at least in the video) than in previous launches that I watched. Maybe it was because of the camera angle looking more at the side of the rocket when usually you are looking more at the bottom.

This makes a lot of sense and it should really be more common procedure, regardless of whether immigrants are refugees or those just trying to start a new life in a different country.

Every country has its own set of cultural norms and these can be thought of as a protocol. When individuals don't perform on the same protocol, you get a tragedy of the commons effect. This is why I think multicultural societies often breed mistrust[0]. That's not to say that multiculturalism is at fault, only that individuals joining a new society may not be aware of the protocol (i.e. individuals can have more than one protocol).

An open society should embrace helping newcomers speak this new protocol, as it would benefit their society as a whole for all citizens and soon-to-be-citizens to understand what cultural norms unite that society and move it forward. Instead of isolating immigrants in ghettos and enclaves, it seems it would be beneficial to everyone if these new immigrants are sponsored by others citizens to help them assimilate faster rather than left alienated and neglected.

I understand this may not be a natural thing for us, since it seems we have a very tribal instinct. I think teaching integration and embracing/helping immigrants should be something taught at a very early age so its an accepted part of society.

> Does SpaceX have any real competitors in the private sector?

They do, such as Jeff Bezos' Blue Origin, United Launch Alliance, and others I can't think of off the top of my head.

However, Musk appears to have a major advantage: At least two major investment banks [0][1][2] and many other observers and investors [3][4] believe a major advantage Musk has over competitors is his relationship with President Trump. They claim it has greatly increased investment in Tesla (and investment indeed has greatly increased since Musk embraced Trump after the election, but of course the cause is impossible to prove and U.S. stocks in general have rallied). If you doubt this is an issue, not only see the cites but search a news index for "musk trump" - it is widespread outside HN.

I don't know about the effect on SpaceX (are they public?), but the space business is highly dependent on government contracts, project funding, and regulation; you can imagine what the appearances are. Compare that with competitor Jeff Bezos, for example, who owns a major newspaper that regularly criticizes Trump; will the competition for government contracts and other benefits be free and fair?

It would be bad for the space industry, the economy, the U.S. as a nation, and the fight for the free market and against corruption if that relationship decided or even appeared to decide the winner in this competition. Appearances are reality on the public stage; if people merely perceive corruption helped him, the (many) unscrupulous people will try to use that tactics themselves and many others will doubt Musk's legitimacy.

I think he has what it takes to win on his own; the other stuff could undermine him unnecessarily, and be bad for everyone else.

Honestly, in my experience that would be consulting.

I've personally always failed building anything that people would like to use enough to pay for it, and I've seen many people waste (or invest) about 10x what they would put into consulting to make less than minimum wage (or even 0).

Yet, I'm still trying.
If you think about it, rapidly reusable suborbital rockets are like a physical version of the communication you describe here. It's plausible to physically be anywhere in the world (if you burn enough fuel) within 30 minutes. Ditto up to 10 tonnes of cargo.
> Does anybody have that?

No. Because it's never been done before. We'll just have to wait and see.

But: for this particular flight, SpaceX claims to have spent 4 months in refurb, and it seems to have been very thorough. Inside information suggests that a lot of this was in upgrading things to current spec. Four months is already a significant time savings on production, which is currently said to be about a year.

I find it hard to believe that reflying hardware won't be economical. But NASA's failure to do so with Shuttle seems to have broken people's brains in this area.
Well, if you go to the extreme case (the entire rocket is reusable with _no_ refurbishment) the cost of rocket fuel is $200,000 while the approximate cost of the hardware is in the range of $60M. So, in the extreme case it would be _massively_ cheaper. On the order of 99% savings.

At the moment, SpaceX is only reusing a portion of the rocket (the first stage, not the second stage or the fairings). And that re-used portion requires some refurbishment. SpaceX estimates it's 30% cheaper per launch right now.

Over the next few years SpaceX will probably bring that cost down (though they won't necessarily pass that cost on to the consumer — they could very well just enjoy the extra margins). I'm guessing they can realistically get to 50-70% cost savings per launch over the next few years.

though they are working on recovering the fairing, and attempting something related to that today.
Yup, I was raised Methodist.. I'm not practicing but I receive their email blasts[0] and quite enjoy them. I never knew the fruitcake wing of Christianity either. I wouldn't even call it liberal, just sensible or normal honestly. Almost everything has gotten that way.

I'm not even sure how I got on that mailing list but I believe it's the Faith in Action list if any Methodists out there are interested in reconnecting or at least hearing what's going on in the community.[1]

> I'm as excited about this as anyone, but this kind of content just doesn't belong on HN.

Agreed, but do you know of a high-quality forum for political/current news discussion online?

Seems like a difficult problem to solve, but it's understandable that people may want to talk about this on HN given the general level of commentary available elsewhere online.
This article resonates with me in so many ways. I barely managed to get into any university in my home country, but once I was accepted to one, I set up a strict and timed schedule of 5 hours of concentrated work each day, outside of classes and other mandatory requirements, and left each evening for recovery. A few years later the structured work payed off and I am now completing grad school at Stanford. I honestly thought I would be working in a video rental store in my tiny hometown for the rest of my life. Let's home the structured approach continues to help into the future.
The amount of these companies that are popping up leads me to believe there is a desire for this type of service. I've always been surprised that the supermarkets around me don't put together Blue Apron style meal kits that one can pick up and make. For awhile I used a local service that did that, and it was incredible.
For all Spaceflight of getting to Space is huge, no matter what you are trying to do.

I'm not sure why it is conflicting for you. Even if they are delusional, you profit from cheaper access to Space no matter why they are going there.
Sounds right to me. Other launchers are probably living on borrowed time at this point. ULA and others should have many more years to capitalize on their advantages, but it won't last forever. They'll either sit there, reap short-term profits, then fade away, or innovate. I'm hopeful it'll be the latter. Tory Bruno, ULA's CEO, occasionally comments on SpaceX discussions and seems to be quite with it.
Arianespace is their biggest competitor, they are the de facto rulers of the commercial launch market, with SpaceX hot on their heels. The Ariane 5 launches twin payloads about 7 times a year, for a total of about 14 total spacecraft launches per year. SpaceX is about at a similar cadence but has yet to hit the overall schedule and mission reliability figures that Arianespace has achieved so it's still a bit of a race. Launching on Ariane is the easy, safe choice. Launching on the Falcon 9 is still considered to be a little bit risky, more so from a schedule perspective (which is still a big deal in the industry).

SpaceX is increasing its launch cadence and reducing its prices substantially (through reusability) so they are becoming more competitive by leaps and bounds every moment. If they can follow through on their cadence increases (right now they are around an average of 3 weeks between launches and a minimum of 2 weeks) and cost reductions (see recent flight) no one else will be able to keep up with them. Their internal cost reductions on reuse are unknown but their current price reductions are around 30%, which is off of their already incredibly aggressive low launch prices. If SpaceX can provide launches at around $45 mil and can launch often enough to satisfy demand reasonably then they'll end up with the majority of the commercial launch business eventually. If you can put your satellite in orbit reliably and save on the order of $50 million then you'd be insane not to do so. There's a bit of an insurance premium with launching on SpaceX currently but that should even out after a while and the huge cost reductions swamp that difference regardless (even if, for example, SpaceX were to blow up another rocket tomorrow).

The only realistic competitor for SpaceX in the near term is Blue Origin, once they develop their orbital launcher which will also have VTVL first stage reusability. The timeline on that is sometime before 2020, but that's likely to be the soonest any real competition for SpaceX's business model shows up. Once it becomes commonplace for launches to involve first stage reuse (which will probably happen over the next 5 years or so) I'd expect a lot of the other rocket companies (like Boeing and LockMart) to come out with similar designs (or go out of business or be relegated to national payloads only). It's a lot easier to put forward some hypothetical "better" design for your next generation rocket when everything is on paper, it's a lot harder to pretend your rocket is still better when you're getting your face pushed in by the competition on price by huge margins on a regular basis.

Once SpaceX has the Falcon Heavy running (which will be even more reusable since the upper stage is a smaller proportion of the rocket) they'll be able to launch nearly anything anyone else can, and at dramatically lower costs. Once they're able to launch GPS satellites (which they've already got orders for) as well as the big national security birds (on the FH) for tens or hundreds of millions of dollars less than ULA then almost all of that business is going to flow to them and LockMart/Boeing are going to have some tough times.
> America starts a similar program to make amends for the awful effects of Trump's executive orders on immigrants, americans, and travellers stuck in limbo.

America, as a nation, is under no obligation to 'make amends' for anything -- least of all executive orders which place the interest of American citizens first.
This article gave me cancer and also did something shitty to my browser history.
Canada is a large and diverse country. It also lives with the imposing cultural presence of the US. Growing up in Canada, I never got the impression of a defined Canadian identity except for one thing: We are not Americans.

For me, nothing demonstrates that more than Canadian rejection of the "cultural melting pot" of the US in favour of "multiculturalism". I went to school in the age where we still sang God Save the Queen and recited the Lord's Prayer every morning, so it's going a fair ways back, but I remember actually being taught multiculturalism in school (which, as the perversity of this sentence shows, was perhaps an academic exercise). I distinctly remember being told over and over again: We are not American. We do not value a society with a single culture that absorbs other cultures. We value a society of many cultures that live together in harmony.

I think you will see a lot of variation wrt things like individualism in Canadian culture. For example, it is probably a strongly held belief in places like Alberta. But maybe in the small cities in Quebec or on the east coast, you're going to get a lot more responsibility for community. The string that holds it together, though, is the acceptance for a variety of insular cultures.

As other posters have mention, Canada limits immigration. I suspect that it would run into very similar issues to what the Australians have had to deal with in the past 30 years if it didn't. I always find it strange that my adopted home of Japan is probably one of the easiest countries in the world to emigrate to, but because of it's very strong mono-culture, immigrants generally do not stay. In spite of my upbringing, I enjoy living in a mono-culture -- a very embarrassing admission, and I invite all true Canadians to come and spit on me ;-)

My understanding is that they are now producing and flying Block 5 Falcon 9's which means no more changes to the hardware.

Falcon heavy is obviously a different kettle of fish but the chat around SpaceX on Reddit has been that things are settling/reaching maturity with Falcon 9
My high school senior English class research paper was on VR ... in 1993. Lanier featured heavily as he was one of the "public faces" of the technology back then, with all of the high-dollar stuff coming out of JPL.

I can't say on Google certs, but I passed the AWS ones - I wouldn't go for developer and sys ops both - they are the same level certs in the same certification path, so it seems like a waste of money to get them both really :)

Quick note, it's "solutions architect" not "system architect".

AWS certs are very focused on AWS products, so may not be helpful for Google Cloud. The developer/sysops -> devops path may be a bit better of the two, as it focuses on how to get stuff done, while solutions architect is a bit more higher level knowledge of putting AWS products together.
> Your neighbor could start woodworking as a hobby [...] and shouldn't expect compensation for inconveniences especially in the case of leasing.

If by doing so causes noise, and the circumstances are unreasonable (e.g. woodworking through the night), a claim could certainly be made under nuisance. An injunction to cease the unreasonable behaviour (e.g. only allowing noise to be made during certain hours) would be the primary remedy, but monetary damages for, e.g., loss of sleep are also possible.
Nadir and Qaynuqa were evicted , not massacred. Qurayza was killed after they betrayed the Muslims in the middle of a seige that Nadir (which had resettled in Khaybar) helped instigate. Khaybar was attacked as a result of that same seige, and after the Muslim victory, they were allowed to keep to their lands in exchange for tribute.

So yeah, not a kumbaya story, but it's sure better than your one-line, sarcastic comment.
It's totally sad, but the ignoring of client responses and repeated redundant requests for information already provided, is a standard psychological domination tactic used by interrogators and ( hey, whaddaya know ) compliance people.

The reality is that an annuity comes with lower volitility and risk.

When you look at the risks for a retirement payout, you need to think carefully. How long will you live? How long will you retain your faculties to manageme investments? What protections do you have against dishonest or incompetent advisors?

Unless you're unlikely to live long, or have trustworthy children or other advisors, the annuity is probably the best scenario.
This is actually caused by the use of the x87 80 bit floating point registers. (Infamous GCC bug #323)

When the float is first inserted into the set/map it has 80 bit precision, but that gets truncated to float or double precision during the store. This breaks the ordering as you are saying, but it's not an inherent flaw with floats as such.

The problem goes away if you compile with -mfpmath=sse because then the math will be performed in the same precision as the storage format.

Bug #323 is responsible for a huge amount of mistrust of floats that they don't deserve. Other compilers don't have this problem because they truncate the floats before any comparison.
