> I have given Starlink very optimistic numbers

Your revenue figures are consumer only. And while you're generous on utilization factor, we capitalised the TCO up front while amortising revenue, and then reduced asset tenure to worst case observed during development.

Flex up to 4 years, let $1mm TCO be paid up front and the rest amortised, and reduce utilisation to 80% ($80k/month revenue) and IRR shoots up to 73%. Take TCO to $3mm ($1mm up front, $2mm amortised), reduce utilisation to 75% and we're still over 20%.

> while "7 million subscribers" might sound impressive on first sight: This is the number of DSL connections subscribed to in the tiny country of Belgium. But for magical reasons Starlink is valuated at a price higher than if you would buy all of Belgium

Well, yes. Starlink connections are more profitable and you can't scale selling internet to Belgium into a Starshield defence contract. Or selling to airlines and cruise ships and yachts and mining operations, all of which pay more than a Belgian.

> some countries in the EU for example years ago created laws that say that whoever opens the street for any reasons has to put in empty tubes for someone to later put in fiber before closing the street again

Starlink doesn't sense in densely-populated areas of the EU or Asia. (And the equivalent for SpaceX would be ridesharing Starlink on someone else's flight.)

> Fiber is dirt cheap if you are allowed to use existing power poles for example

If you have the scale. You're underestimating the risk that comes from having to place infrastructure up front.

Your analysis is pretty solid. But I don't think it's taking into account the fact that you can build multibillion-dollar telecoms business on a few tens of millions of high-paying customers.

For your first example, wouldn't the friction be reduced just by telling patients the business hours of the pharmacies nearby? I hate how this question is always posed, as if I'm supposed to come up with a name and address out of a hat. If it's the middle of the night or Christmas Eve and I'm trying to get medicine for the baby, the provider probably has a better intuition than myself as to which pharmacy will actually serve me. If I ask explicitly, the provider is usually happy to suggest some options. Even a simple web interface listing hours of operation would be better than the current method, where the patient is expected to pick a pharmacy from memory before they even know what medicine they need or how long it will be before they are discharged.

> that's a worldview I have very little time for

Only people who already live in a position of privilege get to have "little time" and settle for worldviews which advocate for a sort of bland tolerance of extremism. I can assure you, for people who are being actively harmed by hateful rhetoric and political policies, "those who are not with us are against us" is absolutely a reality.

I'm developing a web app that makes it easier to view Google sheets (and forms) on mobile. My solution is:

- Expandable rows

- Optional custom row summary

- By default, the row summary is just as much of the row that fits.

- Some data in the row summary is shortened (like a timestamp is reduced to just a date or relative date)

- Sticky header row (with the column titles)

Live demos:

- Custom summary rows: https://veneer.leftium.com/base/g.chwbD7sLmAoLe65Z8/list

The number of humanities graduates ballooned and there were no jobs for it. Also, generally the humanities turned in a direction that the wider population doesn't approve of. Just one example is ugly architecture, ugly paintings, unstructured poems, messy novels etc. Deconstruct everything. Ok, that's a nice hobby but scarcely a job. Engineering keeps the lights on. It gives opportunities to anyone who is willing to learn it. A smart working class kid can more easily learn C++ than all the cultural elite signifiers that get you well-paying jobs in things like law. STEM is an equalizer as opposed to fashion-based, taste-based fields. Even during a difficult job market time, you still have better chances with technical and engineering skills than with expertise in literary criticism or some obscure historical period or art form.

JP is firmly coming from academia (got famous with his lecture videos taught at Harvard and U of Toronto), "the institutions created" him. You just disagree with him, but that's not the same. He's not some outsider to academia.

Academia became very dishonest and people noticed. Maybe the replacements are even worse, but the trust will be very hard to gain back. It's very easy to destroy prestige and consensus and takes long to build it up. Of course self-reflection cannot be expected at all. I don't expect it.

Network connection, lobby, matchmaking, leaderboards or even chats, yes. But the actual simulation, probably not for fast paced twitchy shooter.

Also not just for performance reasons, I wouldn’t call BeamVM hard realtime, but also for code. Your game server would usually be the client but headless (without rendering). Helps with reuse and architecture.

My son almost died in the first 24 hours of life. I said, "There's something wrong. There's something wrong." multiple times and the nurses finally told me, "YOU NEED TO CHILL OUT." I did chill out....

Next morning the pediatrician did his rounds, checked on my son, and immediately started speaking Latin, to go over our heads while rushing around and getting equipment to clear his lungs of amniotic fluid.

Reminds me of what my first engineering boss told me -- "When the people on the line say there is a problem. There is a problem."

Understood. Not my startup, but I would have started the other way round.

Businesses that would be willing to pay (a lot) for such a benefit often will be very conservative. In Germany the majority of medium sized businesses using SAP for example still refuse to be moved to SAP's cloud instead of on-premise.

C-Level types typically are not worried putting their email credentials etc into Outlook cloud and getting hacked this way. They are used to "everything is in the cloud". However, as soon as you mention, depending on the type of business "patents", "sales contacts", "production plans" C's will change their mind.

In Germany, where I am originally come from, all of these businesses are worried about their trade secrets to end up in China, and rightly so.

As self-hosting is very complex you could either make good money with consulting (but this means setting up tech teams in all target markets around the globe, using actual competent humans), or by selling it as a plug&play appliance. With that appliance simply being a rack server with a suitable GPU installed.

And again, for your business strategy the long-term risk of pretty much everyone trying to hack you on a daily basis appears too high to me. You might not have on your radar how serious industry spionage is. You will definitely have a fake utility company worker coming into your offices, trying to plug in a USB keylogger into some PC while nobody is looking.

As an example, proven strategy: Find targets internet uplink. Cut it. Customer calls ISP for help. You then send a fake ISP technician that arrives before the real one does. You put a data exfiltration dongle between the modem and the LAN. You then fix the cut outdoor line. Customer is happy that you have fixed it. Later the actual ISP guy arrives. Everyone will be a bit confused that the problem was already fixed, but then agree that it's probably just the ISP once again having screwed up their resource management. Works pretty much every time.

I don‘t follow how that is the conclusion, nor do I understand your analogy.

Broadband internet via cables, fiber optics, and radio towers is state of the art in telecommunication infrastructure. Satellite is both slower, more limited, and more prone to various disruptions. The capabilities of the wires and the radio towers is also improving. 5 years ago we didn’t have 5G towers, and 20 years ago fiber optics seemed a distant dream. The only thing freezing traditional telecommunication infrastructure in place are dreams of low earth orbit satellites which will never materialize.

If I understand your analogy correctly (which I‘m not sure I do) this is like looking at the new technology of pneumatic tubes and stipulating that all postal delivery will be done using this new technology in the future, and we may as well stop funding the national postal service, remove mail-rooms from our ships and trains, because somebody will build a pneumatic tube that will deliver mail door to door between New York and Chicago.

Because providing infrastructure to remote regions is incredibly difficult through other mechanisms. I don't believe it's hyperbole to say that -- for the goal of improving infrastructure access in some of the most remote and challenging places in the world -- Starlink in particular is one of the most successful pro-humanitarian engineering projects that I can think of in maybe the last 20 years.

Starlink is easily one of my favorite engineering projects. I don't believe anybody has done it cheaper, better, or at wider scale than Starlink has.

It does sound like each server is its own process. I think you're correct that it would be a little faster if all games shared a single process. That said, then if one crashed it'd bring the rest down.

This is one of those things that might take weeks just to _test_. Personally I suspect the speedup by merging them would be pretty minor, so I think they've made the right choice just keeping them separate.

I've found context switching to be surprisingly cheap when you only have a few hundred threads. But ultimately, no way to know for sure without testing it. A lot of optimization is just vibes and hypothesize.

> Every story I've ever heard about "Starship" is how it is going to Mars to take humans there to build a colony

Could this reflect your media diet?

> never once heard that "Starship" will be used to launch even more starlink satellites

That's kind of wild. I understand getting the PR stuff first, but every newspaper I read mentions Starlink whenever SpaceX comes up, unless it's about a launch explosion or Artemis.

> pretty wasteful to blow up starship after starship after starship when they could have spent that money launching normal rockets for their satellite deployments

V3 doesn't fit on smaller rockets. And Starship's launch costs promise to be much lower than the Falcons.

> why name it "starship" if it's just meant for LEO? Because it wasn't intended for LEO, that's why

Starship isn't an interstellar platform...

Congratulations on the launch.

I was recently trying to tackle the same problem (@howie.systems). The hardest 2 problems we had to face were ACL and large files (and large volumes).

How did you solve the ACL part? I worked with a customer that had 200k pdf/images/dwg files on SharePoint and other 1M on samba. It took like a week to sync it all and keep tabs on the access rights of each employee.

How did you solve unpredictable large files: a pdf 2000pages, maybe some A0 in the mix. Or some 4GB power point presentations?

PS: great fan of gather. PPS: say hi to Clinton from me (amy.app) if he is still around. He was our mentor back in New Zealand at the flux accelerator (2016)

It's a mass problem. Instead of imagining the gravity well as something moving away from earth out into the vacuum of space, think of it as a ball that needs to be rolled uphill - even if you give it a huge burst of energy, it's not going to go as far as you think from that one big push, and it's still going to roll back downhill. In order to make it out of the gravity well, you need a lot of focused, continuous energy over huge distances.

There are other factors, too - imagine you're trying to send a penny around the entire equator of the earth, and think of the largest possible explosion you could subject it to without vaporizing it. A stick of dynamite could launch a penny only around a half mile's distance around the equator, assuming ideal conditions, which is about .0025% of the circumference of the earth, which is 10% of the distance between the earth and the moon, and the moon is about 25% of the distance from which earth's gravity stops being a significant factor.

If you carefully deployed a large number of well timed series of dynamite sticks precisely located so that each blew up perfectly beneath the penny at its apex following each previous explosion - you'd need 150-300 sticks to get the penny out past the edge of the effective gravitational well, the point at which other factors in the solar system have the dominant influence - it'd effectively leave earth and start falling toward the sun. At any point closer to earth than that, it will slowly and inexorably return back to earth, reaching up to 25,000 mph before vaporizing itself in the atmosphere (if it fell from the outer edge). If you had no atmosphere, a clear shot, and the "ideal" penny cannon to launch it, you could hypothetically reach escape velocity with only a quarter stick of dynamite.

Incidental bursts of gas, or even outright exploding objects in space are not going to launch a bunch of stuff into much deeper orbit. There's a constant downward pull, and gas and dust creating drag and downward acceleration the closer in you get, and just vast, incomprehensible distances to travel under the influences of gravity. Getting things to go faster than 25,000mph, or reaching escape velocity, without vaporizing the thing you're trying to make go fast, requires as big a continuous explosion as you can make over as long a time period as possible.

I love that AI can whip up an xkcd style "What-If?" type scenario for these questions.

I think it depends on how you're travelling. If you're staying in hostels and moving locations frequently (v common for solo travel), walking/busing instead of uber/taxi, using just one bag is peak. But if you're staying longer or you have your own room, getting rides places etc, then it might be worth having more clothes and dealing with lugging your suitcase around occasionally.

Doesn't even need to be a suitcase, a big duffel bag can hold just as much clothing and be more convenient for carrying around, although you still need to check it at the airport.

Yes it could and they're also mostly just reflecting what the media riles them up with. People don't work out their concerns themselves, they copy the popular beliefs.

Nuclear war is still a risk, as are meteor strikes, but somehow they aren't in fashion at the moment. There are yet other risks that people don't want to think about or which protecting ourselves against would be very painful so we also mostly refuse to think about.

I understood it as, OpenAI is giving AMD money, by buying 6GW of GPUs from them.

But if it results in their stock reaching 600$, then AMD will give back the money that OpenAI spent on GPUs as 10% stock options into AMD.

Which sounds like, no one is really investing in each other, they're both like exchanging money back and forth, where both hope to gain some extra money by propping up the AMD stock with the announcement, hoping it helps make AMD more competitive on the GPU landscape.

Did I get it right?

What's are your metrics of "failure"?

Fremont factory has produced 3 million cars, in a manufacturing hostile/barren California (and thus Nevada gigafactory), covering ~50% cars produced yearly. [1]

> Tesla turned things around by building a factory in Shanghai

~50% are made in China, with ~50% of those being sold in China (well until this year), avoiding significant Chinese tariffs. [2]

Show HN: I made Satlo.io – See all companies engaging with your LinkedIn ads
by hristoff | 2025-10-06 21:38:57+00:00
Hi HN

I built Satlo.io, a LinkedIn analytics platform that helps B2B marketers and sales teams get full visibility into their ad engagement data.

LinkedIn’s native Campaign Manager only shows the top 25 companies interacting with your ads. If 1,000 companies see or click your ads, you’ll only ever see 25 — which means missed pipeline and no way to prioritize outreach.

Satlo fixes that by using the LinkedIn Ads API to surface all engaged companies, calculate intent scores, and sync everything to your CRM (HubSpot/Apollo).

Features:

Unlimited company visibility from LinkedIn ads

AI assistant for campaign insights

CRM syncs and CSV/PDF exports

Multi-workspace team support

We’re bootstrapped, early-stage, and just launched our open beta.

Try it free for 30 days: https://satlo.io

Would love feedback from anyone running B2B campaigns or building marketing analytics tools. What would make this 10x more useful for you?

Nah. That's not how it works. I could retire, but choose to keep working. The idea that you can simply step out is based on the idea that you don't need work.cbut in my case I need it for its social aspects and to stay motivated to do things. I still have the same issues as other people where in the mornings I just want to stay in bed. But I still go to work. Because I know it's ultimately a better choice.

You say it's "not moral or right"; so, what would you suggest? I agree applying the lowest common denominator is not necessarily the best (nor fair) way to do it; but, how do you handle it?

Do we agree that there is some level that effects everyone, even if that level is different? Do we require all THC users -- smoking, edibles, vaping, topicals, etc -- be tested to determine the level where they become impaired?

Consider their situation:

Multiply the number of diseases/conditions by the average number of environmental factors multiplied by the number of genetic conditions which change how they present. The cross product is a MASSIVE search space and the ER doctors need to search it about 1-3 hours (on average).

Sometimes patients lie or mischaracterize their symptoms, leading to uncertainty about the data they get.

The emergency room is a triage center. For every bed that is full, there is back pressure into the lobby and out the door. Their job is to create a priority queue (or occasionally to turn into a triage center) based on patient volume keeping the highest average treatment quality possible, not to maximize treatment for any one patient.

Symptoms alone aren’t always determinative. Many flu-like viruses present with almost the exact symptoms, despite being different viruses and having different impact on the body. The ER may discharge you before the labs come back with a positive identification of the exact virus strain, meaning it may be way more dangerous than the seasonal flu, but they play the odds unless you have known comorbidities.

Even if the doctors make a mistake in the ER and discharges you, there’s a decent chance that will live. The body can fight off many diseases by itself (without doctor’s intervention) and if not, there’s a chance you can make it back to the ER for a second attempt. An ER’s job is to keep you alive during your visit to the best of their knowledge, not to see you through the entire course of your disease. As discussed in the article, there are a shortage of hospital beds in other departments, so Ears end up being a poor stopgap for those.

Chronic diseases became more common as doctors and medicine increased our lifetimes. ERs are not the right place to manage chronic diseases, but it’s de facto where the indigent go for their only health care access and where acute issues related to chronic conditions are managed.

People need massively more hospital care during their last year of life and boomers are going through that time of their life. Hospitals are businesses, so they are min-maxing their capital outlays (how many beds they can support) with equipment and staff. If they overspend, they have to charge more than the already outrageous prices they have. If they underspend, some people will get undertreated and hospital staff will get overworked, but that seems to be acceptable to American society, so that’s what we get.

Medical science isn’t perfect. It doesn’t have infinite resources to investigate every possible condition. You couldn’t afford it if they decided to do every diagnostic test possible.

This kind of service could be very useful since documents can be output in different formats or reformatted simply. I'm searching for a replacement for Word that can handle custom header levels/paragraph numberings in a really simple way. I write a lot of municipal code and would really like to find a tool that provides Word-level headings/numberings and can handle collaborative work in a simpler format. This might be the ticket.

Rivians software is quite good. The number of times I've wished it had carplay was low and is now zero that they moved to Google maps instead of their own in the past 6 months (the maps themselves and the interface were totally fine, but traffic prediction and were bad at times). They are fairly good at changing when change is needed.

The latter suggestion is IMHO a really bad idea for companies the size of rivian. it would cost a lot of time and energy to integrate carplay and android auto very very well. Most cars are already a mishmash of software pieces, so replacing 60% of that with a simple carplay integration might buy them a lot. My wife's car is the first model year from that manufacturer with carplay and it's just horribly done. Duplicate voice assistants, and carplay only uses 75% of the screen (this is not fixed by the software changes in ios26 around this. This is the manufacturer not giving a shit) just to start. Despite all that it is still better than the smorgasbord of shit that it is without carplay. That is not true of rivian. It is already good software that is well integrated. if they moved, the same has to remain true. The upfront cost of moving would be large, not provide tons of benefit to existing customers (it's not in the top 5 for most owners), and they aren't large enough to have parallel software teams, so it would slow down development on things owners and near-purchasers care more about.

In the end good product development is at least as much about saying no as it is about saying yes.

saying yes to everything and making them all options does not actually make for good products (or softwaare)

in the end, they seem pretty good about holding themselves accountable to whether they’re succeeding in their various bets or not. and doing something reasonable with that info. As long as they continur that I'm not too worried, because it’ll lead to the CarPlay if it needs to.
