I don't see how replacing mobile carriers with space based infrastructure is physically possible.

It's not meant to replace terrestrial networks, it's a space-based alternative that serves areas carriers have no financial incentive to cover. Terrestrial cellular towers cost between $150k to $500k per tower, and are not economically feasible in less populated areas. There are also many dead-zones in mountainous regions, since cell signals are blocked by mountains.

Starlink Mobile supplements this, it's simply cheaper for mobile providers to partner with them than do their own buildout. Currently only 5% of the earth's surface is covered by cellular signals. Starlink will push that up to 85+%, and is backward compatible with existing cellphones.


> it's a space-based alternative that serves areas carriers have no financial incentive to cover

In a nutshell: they're serving a market that has less money to spend using more expensive tech than the current industry leaders. Maybe I'm wrong but it doesn't scream "massive profit".


I think Airplanes are going to be pretty profitable. They are sort of running a market cornering operation there. But, there will be competition eventually. Starlink is way faster than the alternatives so most airlines have switched and Starlink has rapidly increased their prices for aviation. Idk if it's enough though, they are definitely running lots of promos for home customers.

That sounds pretty niche. And airlines have already extremely thin margin (that have been eaten by fuel price increase). I wouldn’t be surprised if they drop that type of luxury

It’s another product for airlines to sell and make money off. It also serves to keep passengers entertained and content. It’s going to be a very strong market for Starlink IMHO.

  > I think Airplanes are going to be pretty profitable.
Anything at sea, too. Going on a cruise? The cruise ship can offer you Wifi backed by Starlink for another few bucks. Or even your cell provider could get you hooked right up to Starlink for some phones.

Container ships, military vessels, even fishing expeditions could enjoy an internet connection and cell service.


It's big in the recreational boating community, as those folks generally have the disposable income to support a SpaceX ISP subscription.

Worldwide there's roughly 30 million recreational boats, whereas for commercial aircraft carrying people (not cargo) is more like 30k, so different orders if magnitude. It's highly likely boating would be a more profitable industry to satisfy demand for than airlines in the long term. That is unless they're charging exorbitantly more for airline contracts than personal boat use, which is totally possible.


Amazon Leo just signed delta as a customer so competition is indeed close behind.

I think SpaceX is an incredible company but at this valuation I’d expect it to have something as pervasive as the iPhone or Nvidia chips. It seems to have only small niches.


But you're just looking at internet.

SpaceX has the lion's share of the world's launch market, if you include Starlink.

Delta’s ViaSat based Wireless is fine. The latency is hire. But it really isn’t a competitive disadvantage.

If Starlink becomes common enough on flights, I absolutely believe it will be a competitive disadvantage.

I have been flying a lot post Covid between it being a hobby of ours and consulting - I’m currently Platinum Medallion on Delta.

Frequent flyers choose their airlines for a lot of reasons - which airline has the most direct flights from their city, who has the best frequent flyer program, etc. The latency of the Internet is seldom a factor or the difference between 10Mbps and 50Mbps.

Non frequent flyers just buy the cheapest flights. The major three airlines make money off of business travelers, business and first class flights and credit cards.


would you choose a flight that's $200 more expensive because it has starlink?

If I’m flying for work and Starlink is that much better, quite possibly. My wife’s experience with other in-flight WiFi providers has been quite poor, often to the point that it barely works. Having said that, neither of us has been on a flight with Starlink yet.

Which airline? Airlines have been moving away from land based WiFi to much faster satellite WiFi for years

In this case, it was United, almost all transpacific flights. I've read that United has started to move to Starlink, but only on a few flights so far.

No but the airline might choose starlink. I think a gogo business install is on the hundreds of thousands and annual costs in the tens of thousand for their Eutelesat based system.

Maybe not $200, but $20-$50 for a cross country flight for sure.

I wouldn’t. I have literally never bought WiFi on a flight in the course of probably hundreds of flights. Good opportunity to unplug.

If a flight had in-flight Wi-Fi that cost $50 you'd pay for it? Most people I know balk at $10 even on an intercontinental flight

$10/hr for high speed internet on a flight doesn't seem that bad if you have a good use for it. A single drink can be more

There's enough vast terrestrial areas that have had no other options, so those areas may have pent up demand at least in the short term. However, I think they'll need to figure out how to further lower costs to target those poorer underserved communities that tend to come up in these discussions. That is, unless some sort of subsidy is put in place by governments that know that internet connected communities boost economic values, etc. Some such programs likely already exist in some form in the US, but are largely regional so may take some effort to integrate into those systems.

AFAICT, popular tech companies owned by cult of personalities tend to get overinflated evaluations. I agree that the promise of returns tends to be rosier than reality, but at least SpaceX makes a tangible product and isn't the average AI shilling company with no hope of returns. Here at least they have first mover advantage along with lower scaling costs than their competitors thanks to the rocketry side of the biz. I have enormous respect for what SpaceX has accomplished (even if I'm not a fan of the company's owner, etc.)


It’s already profitable

Profitable-profitable or EBITDA-profitable? https://www.reuters.com/business/finance/spacex-generated-ab...

I don't mean this as a gotcha or anything. I imagine rockets are a capital-intensive business. So are datacenters.


Some very rough math. $16 billion in EBITDA with 9million customers. This translates to about $1800 average annual subscription. Per month this is $150.

Starlink for Land 500GB subscription is $165 per month. https://starlink.com/business/maritime.

That is I think Starlink's target customers are ISP deprived. I asked Gemini estimate the size of that market. It said about 10 million in the US and over a 1 billion worldwide. I assume the Elon is pushing the 1 billion number. The problem I see is that outside the US, not everyone can pay $165 per month for internet.


> Terrestrial cellular towers cost between $150k to $500k per tower

I'd be interested to find out exactly where this cost exists. I would expect the majority of the cost (especially in rural/mountainous areas) to be more with power and backhaul, rather than the physical radio gear. Because it's rural, you should be able to easily just use coverage bands (ie 850 MHz or 900 MHz) with relatively high transmission power. This would easily be able to cover 300 km2.

Because of the higher transmission power, and the fact that the tower would be in the middle of nowhere, wouldn't the OPEX be higher, with smaller numbers for CAPEX?


A lot of the cost is regulatory. I used to work at a mobile provider, and it took months to get permission from all the various government agencies before we could actually start building. Even if the tower is in BFE, you still have to get all your plots to the FCC, you need EPA signoff for batteries and fuel tanks and such. Plus there's always state and local permits of various kinds. We had a custom workflow application just to track all of that and there were dozens of steps.

Cell towers aren't very expensive on an ongoing basis, but every few years you're rolling out the next big technology (we went from analog to 1x to 3g to LTE while I was there) and it's a headache.


Every city has phone lines. A phone line allows you to replace it with fiber. A fiber and a tower has long loves.

A star link server has 5 years.

Setting up a terrestrial network is already done and it was relativly easy because you build it up from most profitable to lowest profitable.

Star link only serves 9/10 Million people right now with already 10k satelites whith only a lifetime of 5 years and if this market is profitable, the margins will go down sign due to other competitors. Which are already working on it.


Well if you make the argument that it will replace terrestrial networks and that's why its worth X trillion $ then yes, you do actually need to cover the 1% of earth surface where the waste majority of people actually spend most of their time.

The question is not if its a good business, the question if its a 2 trillion $ business, and if you only cover the 95% of earth without coverage. That more like a couple 100 billion $ business at best.


I never said it would replace terrestrial networks... you invented that claim yourself and are responding to a strawman.

Starlink mobile is for rural areas, and the other 90% of the planet that's not well served by traditional terrestrial networks.

And 40% of earth's population live in rural areas, so there is a large market for this kind of service.


If its a big market, SpaceX will have to share this sooner than later as plenty of others are working on this.

Nonetheless even in rural areas there is A LOT of coverage.

And starlink has one sig issue: its bandwidth.

For them to increase bandwdith they need to scale which is expensive and they have to reinvest every 5 years in replacing these satelites.

A fiber layed down can work for a lot longer and can be replaced a lot easier.


In regions like Nigeria or the Philippines, Starlink costs over 100% of the average monthly income. The individual addressable rural market really is closer to 1% than 40%.

Starlink Mobile != Starlink

You're talking about the wrong product.

I am talking about Starlink mobile, their direct-to-cellphone mobile data offering, not Starlink internet...


Starlink Mobile actually reinforces my point. Most don't have phones capable of using it. And even at that, it’s a low-bandwidth designed for SMS and emergency data, not a primary ISP replacement. Of course, you can believe what it could be... Much like all of Elons products, they are always coming

5G Non-Terrestrial Networks (NTN) is already part of the 5G standard. It's not a replacement for terrestrial carriers, it's an expansion that enables devices to be always connected and select the appropriate terrestrial vs satellite connection transparently. ~75% of the land mass on Earth has no cell coverage, ~90% if you include the oceans. It's the same transition in theory that we had from landlines to cell towers.

Great, but the overwhelming majority of money is made from the place people actually live. Those places are called cities. Only about a few % of earth are built on, and even among those the top 1% is where most people live.

Don't get me wrong, that fucking great business, but its not 'replacing terrestrial ISP' level great.


They said the same thing about cell phones vs landlines back in the day. Based on Starlink's revenue doubling year on year, and a six fold increase since 2022, I don't think anyone really knows what the upper bounds for global access is yet. And traditional telcos are usually limited to a region whereas Starlink is global. Just the top 20 global telcos alone are almost $2 trillion in market cap and $1.35 trillion in revenue. Starlink has captured less than 1% of that revenue to date.

>They said the same thing about cell phones vs landlines

Did they? I don't really remember that tbh.


McKinsey estimated the global market for cellphones would be 900,000 units in 2000.

They were off by 100 million.

Even until the 90s some telcos believed that cell usage would never eclipse landlines which would remain the base of their business. It sounds ridiculous today because cell numbers outnumber landlines almost ten to one and have been dominant for over two decades.


They did. I worked in telecommunications from the late 90s until 2016. The death of the landline and dominance of mobile was a genuine surprise to the industry. The iPhone was the knockout blow.

my most altruistic view : they said it through actions.

Rural areas were the last areas to join the mobile networks.

This is just a practical thing though; why would you build a tower for a community of 900 people when there are still gaps in the major metropolitan areas? It can't all happen simultaneously regardless of how badly we wish it could.


Absolutely no one said that.

There were a lot of people back in the early '90s who thought cell service would never be widely adopted because of the cost. It was clear you didn't need a mobile phone -- we'd all gotten long just fine without one.

I worked at Radio Shack in 1995 shortly after carriers started subsidizing phones aggressively and you could “buy one for penny”. They were selling like crazy.

Just some quick Googling says that cellphone penetration went from 1% in 1990 to 50% by 1999.

The Motorola Startec was introduced in 1996 and clones came quickly thereafter and were all the rage


Although it’s also the case that people like me owned cell phones for quite a while but didn’t use them to any material degree especially for personal uses for a while.

Per minute costs were expensive, roaming from your local city took a lot of work, they were bulky bag phones and you still had to pay separate long distance charges, I’m not surprised.

Sprint changed that in the late 90s where all calls were 10 cents a minute anywhere you were calling from and too and you stayed on their network.


Exactly. I eventually bought one and then an other and chose a calling area that was most likely to correspond with people I might communicate with on trips and the like but it was backup/emergency use. Not something you used personally day to day or even maybe week to week.

I think that's the point. Nobody in the 80s or early 90s understood how quickly it would grow by 1995.

It doesn't not seem like anything approaching a lucrative business.

TAM: How big is the market for high speed internet that can pay $1200+/year and isn't already well-served by comcast/at&t/etc? And of course, this is all with finite spectrum too. So you can't serve the major cities.

No doubt there exist buyers. But rural Montana doesn't have that many households. Add that 5 year replacement cycle and Musk's Trump alignment that has Europe building their own for security reasons.


> well-served by comcast/at&t/etc

These are US telecoms, the satellites blanket the entire Earth at all times. Lower ARPU, but still. Also, it seems like they're swallowing a large percentage of flight/cruise/military internet. And direct-to-cell data coverage of the entire Earth.


How can this be true? Should I not worry about margin compression at Google due to heavy cap-ex requirements anymore? Is this temporary because Kagi got a good deal for tokens? Are they paying through their noses for the Google search API calls? I don't get it.


Because they pay API costs to send the search to SerpApi. I forget exactly what the cost was for them per-search and I'm having little luck finding it, but I know they've published that cost before and I know it's more than a whole cent. By comparison, running a good but not top-tier model to answer the same question might run a small fraction of a cent. Cheaper than a follow up query by the user.


Then you are kicking full-time streamers like Stodeh, tanking your chances your game has any kind of success.


”Your game”? It’s a publisher making a game. If I’m kicking someone off my server I’m not asking EA/Ubisoft etc.

I’m talking about normal old fashioned server administration now, I.e people hosting/renting their game infra and doing the administration: making rules, enforcing the rules by kicking and banning, charging fees either for vip status meaning no queuing etc, or even to play at all.


Meanwhile Linus argued against Debuggers in 2000: https://lwn.net/2000/0914/a/lt-debugger.php3

But then he changed his tune? Even on LLMs...


Compared to painting, software allows you to solve the problem once, then distribute the solution to the problem basically for free.

Market frictions cause the problem to be solved multiple times.

LLMs learn the solution patterns and apply it devaluing coming up with solutions in the first place.


Well, slightly different take: it's like telling an artist the world doesn't need another song about love, these already exist and can be re-heard as needed. Sharper formulated: a CRM or TODO-list is a solved problem in theory, right? tons of solutions even free ones to use out there. still look at what people are doing and selling - CRMs and TODO-list variations. because, in fact, its not solved, and always has certain tradeoffs that doesn't fit some people.


LGPL means "gift to the world". The license ensures that any modification/improvements stay a gift to the world.

People not being okay with having to share their improvements not being able to use the software is by design.

I don't get how you get from there to some sinister hostage taking situation.

Also everyone that contributes to the previous LGPL verison probably contributed under LGPL only, so it is now just one guy...


LGPL applies to the LGPL’d code, not to every piece of code someone might add to the repository or under the same name implicitly.

The claim being made is that because some prior implementation was licensed one way, all other implementations must also be licensed as such.

AIUI the code has provenance in Netscape, prior to the chardet library, and the Netscape code has provenance in academic literature.

Now the question of what constitutes a rewrite is complex, and maybe somewhat more complex with the AI involvement, but if we take the current maintainers story as honest they almost certainly passed the bar of independence for the code.


This is how opinions differ. IMO plastic is better than aluminium. It is robust (if done right), lighter and doesn't have good thermal conductivity (which makes laptop usage possible, MacBooks can be uncomfortable for lap usage if too hot).

The metal is more "luxury", though.


> MacBooks can be uncomfortable for lap usage if too hot

This was definitely the case in the Intel era, but I can't say I've had this problem since the move to Apple silicon


I have an Air. Maybe active cooling prevents it from getting too hot. With the Air, the metal body is kind of the heatsink.

I can configure my Snapdragon plastic laptop such that the fan doesn't turn on, so the body being metal isn't a requirement for not turning on the fan...


If the body was a heatsink, it would be extremely hot to the touch.

https://hothardware.com/news/make-your-m1-macbook-air-perfor...


From your link:

Essentially the bottom cover of the MacBook Air becomes one large heatsink

Anyway, the author claims:

you are the type that likes to work with the MacBook Air on your lap it will be quite a bit more toasty than before.

Does toasty mean extremely hot?

The Apple M4 CPU is, if I recall correctly, capable of converting 20 watts of electrical energy in to heat, at full throttle.

Is that likely to bring the back plate or a MBA above 45 degrees?

You’re probably right, with sustained workloads it could.

Everything’s a trade off.


In a Notebookcheck test, they got the bottom plate up to 43C, and top plate near the screen up to 45C: https://www.notebookcheck.net/The-passively-cooled-M4-SoC-ma...


hence the Neo and the iPhone chip!


YOU GUYS IT HAS A HEADPHONE JACK


Don't all macbooks have one?


Makes me wonder if this is an ADA requirement for education devices. (assistive listening devices)


Not even ADA - kids all get headphones to listen to education materials. Wired headphones are way, way easier to manage.


It's almost as if they weren't lying when they said dropping it in the phone was a waterproofing measure. I guess people aren't dropping their laptops in pools all the time.


There’s also plenty of room for it which is why it continues to appear on all MacBooks.


This isn't news, all MacBooks have one.


> MacBooks can be uncomfortable for lap usage if too hot).

My body is the heatsink


Also for males it is natural birth control. Can be a plus depending on your situation


I think the 14" and Air might get a little warmer, but I can't recall a time I've felt heat from my 16" M4 Pro, fan sound is rare. On my 13" Intel, it was comically easy to cook my balls and the fans were at max constantly


Plastic is better if done right. I do not know a single manufacturer today which does plastic right.


> plastic is better than aluminium. It is robust (if done right), lighter and doesn't have good thermal conductivity (which makes laptop usage possible

Yep. I miss my plastic phones too.


I'd go further and suggest that metal is a lousy substance for laptop enclosures.


Idea for using the betting/data or other statistics about potential train delay:

One gets back 50% if reaching the destination is delayed by more than 2h. Schedule the journey such that this is probable, making the journey 50% cheaper. Potentially with being able to define where one should be stuck waiting for the next train connected with sight seeing opportunities (such as the nice quarter near the Frankfurt main train station -- old ECB building!).


In 2019 there was a talk about data mining the DB arrival data [1] (yes, this problem is nothing new). One of the takeaways was that on some connections you can actually buy a "Sparticket" (cheaper, but only valid for a specific train), but get it upgraded to a "Flexticket" (more expensive, can take any train on the route) for free. This works because a delay of more than X minutes removes the specific train requirement and some routes are nearly always delayed by at least that threshold.

[1] https://media.ccc.de/v/36c3-10652-bahnmining_-_punktlichkeit... (German)


For international through Germany we used to get 100% back after four hour delays but they stopped doing that ... For obvious reasons. I traveled for free multiple times in the (long) past. Also fun of you wanted to get more back: if you had a first class ticket and reserved seat and had to switch trains and re-reserved you would get a free ticket with a stamp price for about 5 euro. Which you could ask back. So you got at least a coffee for free.


Maybe review your media consumption for if they are reliable


Anthropic giving away Claude if you get 5000 stars doesn't help either


I'm pretty sure it's not "if 5000 stars then free Claude". It's just an initial limit before they bother a human to check if your open source project is valid.

Just like Jetbrains gives away IDEA licenses for open source projects, you need to have some metrics go up before they even consider you.
