I don't think SpaceX would break Earth satellites. Isn't it trivial to remove a light streak from a picture? Satellites were a problem before SpaceX and I'm sure it's 1 click in some software astronomers use. The surface area of a streak of light must be less than 1% of the total surface area so virtually no information is lost. If you use multiple exposures it's even less. Seriously, an astronomer who can't deal with this problem should just give back their PhD. The idea that humanity should be prevented from extending internet access to the entire planet because an astronomer finds it too inconvenient to click a button is example of entitled behaviour on a scale I've never encountered in my life.
If this provides unfiltered internet to regimes which dislike it, will we see them blowing satellites out of orbit?
Instead of using the "How" title, it'll be better to use the answer as the title.

So instead of "How satellite ‘megaconstellations’ will photobomb astronomy images" it would be better with "Starlink satellites might interfere with space observations from Earth" or similar
Your link describes a failure of SpaceX's internal ticketing system which resulted in ESA thinking that SpaceX were ignoring them.

It seems unfair to paint SpaceX as anti-space telescope on that basis.
This is already better than anything I can get (rural NZ). Any info on service tiers and pricing?
The words "macho" and "machismo" come from Portuguese. I've been told that Latino South and Central American machismo culture is very toxic compared "even" to US standards.

But then again, I didn't really put much stock in vague generalizations like this, or yours.
If only there were some existing available technology designed to make satellites hard to see or otherwise detect.

Oh well. Too bad nobody’s ever researched that.

The issue of updates not installing may have saved you from worse issues.

Here is a description of updates from June which caused me significant trouble:
https://www.windowslatest.com/2020/04/06/windows-10-update-k...
https://www.windowslatest.com/2020/03/17/windows-10-kb455176... (other patch)

From the first article: "Another user also told us that the KB4541335 update crashes the system and later causes 100% disk/CPU usage."

That is pretty much what happened to me, especially the hard drive grinding. Also discovering that I couldn't use F8 to boot to safe mode any more. I discovered I had to wait a very long time to get to the login screen all the time with the HDD grinding and then shift click something to get the menus to be able to do a system restore without loading a user profile.

Note to anyone using Windows, always have a Windows PE environment ready to boot to, even if you are a home user, it may save a lot of trouble.
Yes, but it should be noted that average delivery times may hide the severity of the problem. At least from anecdotal information, it sounds like some letters are arriving as usual and a smaller subset are severity delayed.

I think the median and mode delivery times would be helpful numbers rather than just mean.

Awesome!
That is incredible
This is a good question, I see three main reasons but I may miss something:

1. Hop count is not one on the ground to go same distance.

2. Speed of light is significantly faster in vacuum.

3. The path is potentially straighter for longer distances.
I recently moved out of the city after many years and looked up at night for the first time in a while and was surprised to see so much stuff moving around. The first time I saw something I thought I was really lucky to catch the ISS but after seeing the "ISS" many more times in the following minutes I quickly realised it was SpaceX and friends' satellites.

I also recall last year looking up and seeing a string of about 20 bright lights moving quickly across the sky and wondering if it was the start of WW3. Turns out it was a SpaceX launch.

I disagree. 80s home computers camev with an interpreted language built in, and you were 5 seconds from power on to writing code. In addition, everything was accessible easily via comprehensible commands, directly. I don't think that's the case today, and in addition the bar is immensely higher than it was in the past. Commercial games in the early 80s looked like the kind of things you programmed yourself, whereas I think any title my kids play now looks like a cgi movie, and is the product of hundreds or thousands of people.
I don’t get this argument.

If you have to rely on companies’ good conscience long term you will be lost and abandoned. As such individual acts of ethical behavior are maybe nice but not really very important or meaningful.

It’s much better if companies are structured in such a way that their own self-interest aligns closely with the self-interest of society at large.

Such a match will never be perfect, but if it works it’s quite nice.

I would argue that Apple is at least in some ways structured so that its own self-interest regarding privacy results in positive privacy conscious outcomes for everyone.

It’s of course good to know that generally speaking companies will always act in self-interest but if self-interest leads to positive outcomes then that’s much more stable and longer-lasting than some CEO acting out of the goodness of their heart. That’s fickle and can just disappear any second.
This social issue is tied with IT, HN and communities/companies alike. It shouldn’t be flagged because it’s hard for many, it should be talked about. Women in tech are treated like second class citizens.

But maybe i spent too much time in tech social media and I see those patterns regularly. Eg. Abuse woman online, if she starts talking about it, discredit her skills, and try to humiliate as much as possible, presenting it as a snowflake kind of attitude.

All of this is typical “nice guy” kind of shit.

Hard question. We will see. Take GDPR, only applicable, though extraterritorial, to EU residents. So if on a yaught or extra-EU for 183+ days? Plus multiple other territories doing GDPR similar.

Interesting to watch. And most of the world does not live on yaughts. I think the answer will be a lot of deals. I'm in China and Elon is putting in a lot of energy here, and with Starlink a big potential conflict of interest with Starlink vs Tesla. Not sure how fickle that is. We will see.
Depends on where on the +100ms range we're on. Once you start hitting 1s latency, lots of applications (or rather, their servers) have a hard limit on 1s for every request. So when loading data from the backend, you have to continue to retry the request until it gets below 1s and then you will finally get the data.

I think Adobe been one of the worst companies I've dealt with personally, as many of the endpoints have ridiculously low timeouts (for someone with really shitty latency).
>China is a poor, third-world country.

No. It's a very dangerous economic and military juggernaut that abuses its population as well as the environment. Let's be real.

I would also be glad, if you could just look at the sky and don't be disturbed by satellites and air and light pollution. I think, SpaceX and others will eventually manage to make the satellites less or mostly not disturbing. But lets face it, SpaceX actually enables better professional astronomy because launching a telescope into space is now much more affordable. Also all those remote locations, where normal earth based astronomy still kind of works will have a usable internet connection to transfer the results e.g. for computation and further instructions. Also scientists will be able to e.g. video-talk home which should make these long trips into nowhere more socially acceptable in their respective families. I can imagine, that would make some of that research more surmountable.
Isn't the solution more satellites for astronomy? In fact, couldn't the constellation of commercial satellites be used to make a massive distributed hubble telescope?
Ask HN: I'm building an easy-to-use video editor, tell me your pain points
Pretty much, what's in the title. My focus is to be extremely easy to use, and I want to cut video editing time at least 5 fold.

My target audience is beginning youtubers, youtubers wanting to grow their channel.

With that in mind, what are your biggest editing pain points? Those that drain you out, and take most time? Thanks for sharing!
I do this and it has downsides:

* muting yourself is not clearly visible to the conference app (Your face doesn't get a mic with a strikethrough on the screen).
Apps that warn you that your audio device is receiving audio but you are muted on the application level no longer work correctly.

* some apps (Looking at you, Teams) will actually complain that you seem to have deactivated your audio device (of course you did - that's the whole point).
Currently:

ground <--> satellite <--> ground <------------> ground

With satellite links:

ground <--> satellite <--> satellite <--> ground

i.e. the sat-to-sat link should be faster than the ground-to-ground link, on the basis that light transmitted in vacuum goes faster than light transmitted in glass. That's the theory at least.
Is there a way to use this on the go, battery powered? I wonder if it would be a good alternative to using 4g or 5g networks. How does it work indoors? Does the antenna/receiver need line of sight?
Infringement.
> there is so much more demand for global, low-latency wireless internet than for astronomical observations.

This is very much not true and a remarkably narrow utilitarian view.

I understand US folks are poorly served in terms of ISP infrastructure and competition but please don't try to project those issues as a 'global' problem.

Internet service is a solved problem, you have transoceanic cables and distribution networks which garantee reliable, high bandwith, _wired_ internet service.

Wireless service is a solved problem in densely populated areas, again the issue in the US is the ludicrious pricing of mobile data plans.

The only use-cases that this serves are high-income people that want to go off-grid but are unwilling to sacrifice high-bandwith, and military deployments (Which SpaceX does not hide as an objective). To me these are very poor gains for all the negative impact it brings to science and the 'global' public.
Yep. That was intentionally put at song start :)
Living in a city, I didn't understand how big a deal this was until I got a view of the clear night sky in a less populated area recently. The satellites are already visible by eye everywhere, and there are only 655 Starlink satellites. There's approval for 12000, and SpaceX is seeking approval for 30000!

If they're all going to be this reflective, satellites will be the main thing we see in the night sky a few years from now. Forget about astronomy; 10 years from now you'd be telling your kids "when I was your age we used to be able to see constellations of stars in the sky". By eye, only about ~5000 stars are visible in the night sky.
Good work !
PS is NFS still a thing ? I thought Gluster(FS) or S3 sorta replaced it in most shops ? I could be mistaken of course.
Is your point that her politics are bad enough that she deserves this harassment, and is wrong to complain about it?
There is so much unwarranted alarmism about this. This is not the end of astronomy, nor is it even super serious. The "unavoidable impact" they're talking about is that astronomers will have to care about when and where satellites will appear, rather than not bothering and just throwing away the rare image with a satellite in it. A small percentage of their pixels will be affected by satellite trails and they will need to implement better algorithms to avoid them, remove them, or use different sensor technologies that can reject them better.

Sure, if you're an astronomer this is annoying, and will cost you some effort and money and time. But you'll still be able to do astronomy. Meanwhile, if you're not an astronomer, the satellites will not be visible to the naked eye in their final orbits. The entire surface of the Earth will gain low latency broadband internet access for the first time, and new launch systems will drastically reduce the cost of access to space, enabling more space-based astronomy.

> A negative externality is any difference between the private cost of an action or decision to an economic agent and the social cost.

Like pollution, I think this is another perfect example of a negative externality. A few companies stand to benefit quite a lot by incurring costs and risks onto others. Maybe these its possible for astronomy and other endeavours to work around this but it doesn't seem fair that they should have to be the ones to pay for it. If it isn't possible to work around then I think we have a bigger problem here.

Personally, I'd like to see these orbits like realestate which are commomly owned and democratically managed by all of humanity. Then companies could, if people are willing, temporarily rent them with proceeds equally distributed. Like in pollution, I don't think market demand for wireless Internet really suffices as a vote here and we need to make it more explicit to really gather consent.

Wouldn't it be neat if the net result is that capturing the negative externality actually funded the launching of better space based telescopes?
More like this:

Currently:

ground <--> satellite <--> ground <--> ground farther away via legacy infrastructure

With satellite links:

ground <--> satellite <--> satellite <--> ground farther away directly
Last time I mentioned latency all the fanboys squealed about how latency isn’t a problem any more with low orbit satellites.

Whatever.

Light travels through glass (fiber optics) at 2/3 of the speed in vacuum. So as long as you are skipping some ground links by doing similar length links in space it is faster.

Low altitude orbits mean that the hops up and down can be compensated by faster hops across.

That all of course is not there yet and depends on Starlink implementing the cross sattelite links.
Voice chat is obnoxious with more than a few tens of ms latency.

Are you seriously proposing totalitarian internet? So let's think who would adopt it first. My guess: China, Russia, Belarus, maybe even North Koreans would finally join internet.
I don't think you'd need a separate internet for that. You can have some kind of ID system where you can authenticate to a site with your ID. Some sites essentially use small credit card payments to do this already. This commonly helps prevent ban evasions in online games that cost money.

Correct. Torvalds built his PC himself and his words are quoted in the ZdNet's article to which the video author refers to as he builds a "copy" for his youtube channel.

First and foremost democracy needs government which is funded by the people, not other way around. In today's Belarus, this is not the case; in the near future, it will not be the case in most or all large Western societies simply due to technological reasons: automation will make most people unemployable and dependent on government handouts - either direct, in form of basic income guarantee, on concealed, through public of private "bullshit jobs", that create no economic value but exists just so these people can consume and keep the wheels of economy rolling.

Have that, and democratic society with freedom of speech, and you get a self-eating monster machine that will destroy itself in less than a generation. Why does someone who has no chances to be self-reliant, vote responsibly? Especially if he is well-educated and well-informed, so he realises it.

I personally believe that pervasive high speed internet even in remote locations will do more for humanity than the scientific cost of these satellites.

However, this conversation has basically been skipped over. Maybe you're right and I'm wrong.

The constellations are being launched, and there's zero chance of shutting them down once they're serving a commercial role. Considering the abundant red tape in the modern world, it does seem like it was a little thin on the ground here.

I'm sure you do, Chief.
> will cost you some effort and money and time.

This externality needs to be captured for it to be fair.
Actually it's not. There are objective benefits to society that you simply ignore.
I'm not entirely confident in answering that directly, so perhaps you can check my reasoning here.

If F is completely unknown, perhaps you start training with a 10 dimensional polynomial basis. What is the (computational) cost of obtaining your solution? Once you have it, will this polynomial accurately represent your system in any real world manner? Perhaps higher order parameters are needed to approximate trigonometric functions - are you able to easily add such functions to your training basis? If not - then your basis could be too restrictive to provide you with a minimal implementation of your control variable.

It looks like you work with this stuff far more than I have, so perhaps that's not an adequate answer.

Another way to look at this though: If you only wanted to characterise your system with polynomials, UODEs + SINDy can do this for you - the NN is simply the optimisation method that's in place of any other optimisation algorithm.
Just as a heads up, you'll be downvoted, not because you're mentioning latency, but because your comment is low effort and basically complaining about discussions in a place where discussions are kind of the point.

Is there any new information about latency since before that you want to expand on?
I think the premise was that such investments are wasteful if it's only for a trading arms race.
It's not as big a deal as you think. The satellites are only visible to the naked eye for a few weeks after launch as they travel to their final orbits; after that they are too dim to see. The sky will not appear different than it does now to the naked eye; you will never see thousands of satellites. Most of the bright satellites you see now have been there for many years already; Starlink will not be visible like those.
For example: https://www.kinguin.net/category/19429/windows-10-profession...
Will those american billionaires pay say for more European satellites to compensate? What if this were Chinese satellites would you have the same opinion?

It would be great if this billionaires would also launch scientific satellites payed from their pocket to compensate, then I would change my mind.
If you're talking about boolean satisfiability, all you have as "memory locations" are bits and you describe their relationships. I guess the result you want is "unsat".

Say you want location 1 not equal location 2, then you have

(1 or 2) and (not 1 and not 2) in the expected normal form. This blows up fast if multiple variables are involved. There are tricks like Tseitin transformation that can reduce the size of the clauses but introduces additional variables.

Also, if you want to use 8-bit-numbers, you'd need 8 variables each. Addition would need more clauses.
