Dabir posted:Starlink is a money-sink scam to get money out of the government. It uses a ridiculous number of satellites to provide coverage that other providers are managing with a handful. These satellites are short-lived junk that are clogging up the sky and ruining ground-based astronomy. The ground dish is a non-repairable unit that even professionals can't tear down without outright destroying them - you can't even replace the cable without getting a new dish. It also fails in high temperatures (like what big swathes of the US are currently experiencing) and low temperatures (so Svalbard is right out, sorry). i hate elon as much as the next right thinking person but this is horseshit sorry Inmarsat will give you similar data rates but charge you 10x for the privilege and the coverage isn’t as good. Intelsat and iridium data rates are orders of magnitude slower. Oneweb has burnt through the full gen1 constellation without providing a consumer service (including sucking down a huge wedge of taxpayer cash in the process). Telesat are still talking on paper after ten years. Starlink works and at a price point which competes with the terrestrial market. They are nearly a generation ahead the competition and not slowing down. They’re about to be the first to get intersatelite links working and beam hopping wont be far behind The impact on ground-based astronomy is poo poo tho :/

That is actually a problem as I believe the satellites obstruct telescopes, and depending on where you launch satellites it creates a problem whereby the orbit around earth gets increasingly filled with fast moving objects, which if they collide will destroy anything else we want to put in space. The big threat is the possibility of this becoming a runaway problem, as one collision could shatter the objects into thousands of smaller pieces, each of which could go on to impact more objects and create more fragments, resulting in a deadly belt of debris encircling the planet. The more impacts, the more fragments, which means more frequent impacts, creating a runaway effect. Lower orbits are safer because the earth's atmospheric edge will slowly decelerate anything close enough to the planet, causing it to crash, but higher orbits could take geological timescales to clear, rendering them much harder to use for future satellites. https://en.wikipedia.org/wiki/Kessler_syndrome OwlFancier fucked around with this message at 22:39 on Jul 29, 2023 |

Leo has a high density of debris but it decays quickly and (to a certain extent) self regulates; meo is the guilty party for long term debris pollution They might mean spectrum congestion tho idk, still shouldnt be a concern to anyone who isn’t a specialist being paid to manage it

I'm not losing sleep over it, just pointing out that the sky actually can get clogged up with satellites and elon musk is exactly the kind of moron to start firing cluster bombs into space for a joke and cause a lot of problems for everybody. Him causing problems that far more intelligent people then have to clean up, is basically his entire life. OwlFancier fucked around with this message at 22:51 on Jul 29, 2023 |

Not 3,000, 3. He needs that many because he wants them in low orbit for lower ping, because pro gamers are totally going to use satellite internet.

From what I remember, Starling shouldn't cause a Keppler situation as their satellites are at a considerably lower orbit than anything else up there. They do screw up stellar photography though as such photography requires long exposures for which these satellites then leave long streaks on the image. As a side note, I have a friend that works in space journalism. They say they are very wary about what they say about SpaceX in case Elon decides to throw a major wobbler and kick them off Twitter if they say anything negative.

Dabir posted:Space isn't a series of solid shells that objects can neither enter nor leave without our aid. If a Starlink satellite collides with another one, its debris will go in all directions. Sort of, depends what it collides with. If they were all operating mostly in the same direction, then the debris would still go mostly in the same direction. The biggest risk for satellite colisions is if they're in a high inclination orbit because that necessarily crosses all other possible orbits at that altitude. Not familiar with how starlink works but presumably if they're trying to do communications from low altitude they would need to do some fairly high inclinations to reach the northern hemisphere. So that would certainly be a concern. But even then, the debris should struggle to gain significant altitude for the most part, and a lot of it would likely become eccentric and re-enter the atmosphere immediately. The bigger concern for me personally would be if he decided to start launching them at higher altitudes to prolong their lifespan, because that also puts them further from the area that is affected by atmospheric drag.

It kinda is, that's what Gravity wells are? if you have satellites a certain height from Earth, they aren't going any higher unless you boost them with rocket fuel. Because you need to fight against gravity. And LEO is low enough that stuff burns up in the high atmosphere fairly quickly anyways - hence the having to replace the satellites every 5 years.

Sigh...don't you just love learning lessons? Well, I've learned a big one this month. Sharing here so you don't have it happen to you. I'm privileged enough to have the best job I've ever had at the moment, Product Manager at a hotel tech company. Once a year our payroll/accounting team tells us to check our HMRC accounts and inform them if we've had a change of tax code. Every other year I've ignored this, as normally at the end of the year it just gets taken care of when they see my real salary, job done. But for some reason this year, I checked. Thought it was good I did, because I DID have a new tax code this year, something like K331. Told payroll, didn't think much of it. Got this month's payslip: dramatically lower than last month. I've had little glitches before where I just contact payroll & they sort it so wasn't TOO worried. Checked the fine print, saw the big change was due to a large increase in PAYE. Looked online, said to call HMRC. Called, 1.5 hours on hold. Spoke to admittedly a very nice woman, who explained: in April, I was lucky enough to receive a large bonus. When my work submitted my wages YTD, someone (either our payroll software provider or HMRC themselves) decided: that one month outlier over the past 12 months? Yeah, better extrapolate his yearly income off of that (their fuckup #1). By doing that, they estimated my salary would be over the limit for the tax-free threshold, so my allowance would be £0. Which meant I'd underpaid taxes so far this year, so they'd better deduct ALL the underpaid taxes for the year, from my July paycheque in one go, instead of their usual method of spreading it out through the year (their fuckup #2). Which meant an additional ~£1800 off this month's cheque, on top of the normal income tax 🙃 Told them ok, it's obviously a mistake, how do we fix it? Oh, don't worry, we'll tell your work to put it back on your next cheque. This was going to be a bit of a tight month anyway, but now we'll have to dip into savings to cover bills. Thankfully we're not living cheque-to-cheque, but still a very unwelcome surprise. Annoyed at myself because if I'd been lazy and not told work about the change, nothing would have happened (as they would have seen at the end of the year that the salary estimate for me was overstated). And if I'd been diligent when I saw the change (researched online what it meant, checked the estimated salary they had for me on file, etc), nothing would have happened as they would have changed the estimated salary & fixed my code. But because I fell into that sweet spot of sharing the code change, but not looking at what it meant: now I'm out of pocket for a month with no recourse but to wait. Infuriating! Maybe everyone in the UK already knows that just like not talking to the police, you shouldn't talk to HMRC, but I'm not from here so I didn't realise. An unwelcome kick in the dick!

I unfortunately have to deal with HMRC a lot as a freelancer and the key things to bear in mind when brown envelopes come through the door or you’re on the phone are They are wildly understaffed They are hilariously incompetent Their computer systems are absolute dogshit What one person says to you will 99% be contrary to whatever the next letter says Much like those old dodgy Wonga loan lenders they have their own in house “pretend” debt collection agency who they will sometimes pretend their letters are from And, bear in mind, I have a good accountant who I pay money to deal with these Cunts and this poo poo still goes on non stop

Yes if you're paye it's never worth talking to hmrc unless you're being massively overtaxed. I would suggest you talk to your work and explain the situation, and instead of them in effect double paying you in Augusts pay slip they might be able to advance if not all, at least some of it to you straight away. We've done that for similar mistakes before.

I’m a bit late to the Starlink chat, but the real reason it’s bad is because it is completely unnecessary and uses vast amounts of resources to do something that no-one really needs. Super fast low-latency internet is an absolute luxury and laggy (600ms, holy loving poo poo) satellite internet that only uses three satellites and currently costs a lot of money is a much better use of finite resources than launching 42,000 bits of short-lived junk into the sky. Starlink is not a long term solution to anything, it’s a way to make a quick buck, gently caress the consequences. The money and resources being used to get Starlink up and running, much like everything Musk does, could be a far better employed elsewhere and make a material difference to people’s lives. Elon Musk is a complete piece of poo poo who has somehow PRed his way into making people think he’s one of the good guys. No billionaire is one of the good guys, and if you make an exception for Elon Musk, you probably need to critically evaluate why that is. Edit: I am old enough to remember a time before the internet, so I am still impressed when my computer starts up in less than 10 minutes and I don’t need to wait for a phone line to be free to get online.
