Under GDPR if a company processes European user data they're obligated to make a "Record of Processing Activities" available on demand (umbrella term for a whole bunch of user-data / identity related stuff). They don't necessarily need to store them onsite but they need to be able to produce them. Saying you're an internet company doesn't mean you can just put the stuff on a server in the Caribbean and shrug when the regulators come knocking on your door

That's aside from the fact that they're a publicly traded company under obligation to keep a gazillion records anyway like in any other jurisdiction.

So, most of the power that Starlink satellites use go into the comms, right? Blasting out electromagnetic radiation to receiver stations on earth, and also the laser(?) backhaul between satellites.

Modulo some efficiency losses, most of the electricity it generates is leaving the satellite. Contrast with a datacenter, where most of the energy is spent heating up the chips, and the rest is spent moving the heat away from those chips.

Thanks for the response :)

I think I get it. If we could convert 100% of the waste heat into useful power, then all good. And that would get interesting because it would effectively become "free" compute - you'd put enough power into the system to start it, and then it could continue running on its own waste heat. A perpetual motion machine but for computing.

But we can't do that, because physics. Everything we could do to generate useful energy from waste heat also generates some waste heat that cannot be captured by that same process. So there will always be some waste heat that can't be converted to useful energy, which needs to be ejected or it accumulates and everything melts.

Why does publishing papers require the latest and greatest GPUs? My understanding is that the paper talks about very general principles.

> So I guess I'm wondering if I should buy a GPU myself or should I just rent on the cloud if I wanted to start getting some experience in this field. How do you even get experience in this normally anyways, do you get into really good schools and into their AI labs which have a lot of funding?

Unless you have money to throw around, you'd better start working on something, write some code and get them running on a leased GPU, before deciding on a long term plan

I've been programming for 60 years. I started working with LLM in mid-2025 and have created a number of useful tools in my consulting business. For the programming part, and actually the planning part, I estimate that it increases my productivity by a factor of 5.

Additionally, I always am looking closely at the code and I think I am an incrementally better programmer.

I think people's intuition is generally reliable, though. What food has the term "UPF" helped you learn is 'unhealthy', which you otherwise would have thought of as healthy?

For losing fat, "fried chicken", "chocolate cake", and "sugary drinks" are intuitively unhelpful, and "vegetables", "lean meat", "water" is more "healthy".

Heat travels when there is a thermal gradient. What thermally superconducting material are you going to make your cube out of that the surface temperature is exactly the same as the core temperature? If you don't have one, then to keep the h100 at 70c, the radiators have to be colder. How much more radiator area do you need then?

Have you considered the effects of insolation? Sunlight heats things too.

How efficient is your power supply and how much waste heat is generated delivering 1kW you your h100?

How do you move data between the ground and your satellite? How much power does that take?

If it's in LEO, how many thermal cycles can your h100 survive? If it's not in LEO, go back to the previous question and add an order of magnitude.

I could go on, but honestly those details - while individually solvable - don't matter because there is no world where you would not be better off taking the exact same h100 and installing it somewhere on the ground instead

My heat pump dryer does not blow cold air into the room. (My heat pump water heater does.)

The air inside the dryer is cycled through a dehumidifier and then the water is pumped out into a drain. This is in contrast to a typical US dryer that just blows hot air into the drum and then out a tube outside. Apparently most of the world doesn't do it like we do.

I just checked, Puluni does have a good track record of keeping up with AWS. But using a non industry standard framework (Stevio) just doesn’t make any sense from a long term portable career perspective.

While I’m not a fanatic about which one I use out of the major ones. My last three projects were CDK/Typescript, Terraform and CloudFormation with my own collection of utility scripts I’ve used over 5 years to make it act more like TF. But the CFTs are standard.

With regards to a community, I once heard someone say that it takes 10 "atta boy"'s to counteract 1 "you suck".

I also remember, roughly 10 years ago, people saying that the amount of effort to discredit bullshit is wildly out of whack. Which makes bullshit basically asymmetric warfare.

So here we are, in this thread, actually spending time attempting to discredit bullshit.

Terms like left and right only have meaning in one place at one time. So just because European conservatives 100 years ago believed something doesn't mean American conservatives today believe in that thing. That's why political scientists have terms like socialist, fascists, libertarian, etc. That's how US right (libertarian) is basically nothing like the right in Europe (conservative). That's because the basic axis of differences in the US is larger vs smaller government and in Europe it is completely different as both sides like larger government. I have tried to explain this to many Europeans over the years; somehow you are all allergic to understanding it. Its probably the only thing you all have in common.

If you rejected economic orthodoxy and bought Bitcoin/Gold over the last.... decade or so... you won over the economic orthodox believers.

I don't really care about short term gold gambling with ~1-2 year market spans or altcoins if you want to disagree.

The biggest threat to bitcoin and gold is something breaking their scarcity. Gold, nuclear chemistry. Bitcoin... quantum computing or something(ignoring rollback).

Nah, hedging war is a meme, but I labeled it as such.

Startups that wanted to treasury in BTC or GLD, were told no, and were vindicated in hindsight are not a meme. Startups that were force-fed 10% inflation and a collapsing bank aren't a meme. That happened.

You can complain that it's irrational to hedge against these things which have been happening an awful lot lately, but you aren't the one who gets to decide. If an enterprising alternative VC is peeling away good founders by being flexible on this point, YC's option is to compete or let the deals go.

> I'm not Christian.

Apologies, I assumed such from the way you described architecture. Few western religions have influence on architecture as much as Christianity.

>Scientology's "highest teachings" are kept private. Its primary purpose seems to be raising money by abusing people's naivety. Compare that to the Christ's « love thy neighbor as thyself. » Very distinct essences.

That's your assumption. I can easily assume that Catholicism primary purpose is to hide a ring of people who engage in rape and pedophilia. There are different angles to every religion, you're just indoctrinated with the most populist angle. In the same way much of the west doesn't realize the religions of tibet and falun gong have cult like aspects FAR worse then scientology.

>Which one promotes social stability?

Both. Morality is not required for stability.

>I think you've essentially said « I don't care whether people around me get slaughtered, because I'm not the target audience. » Allow me to find this self-centered. And still to find it okay-ish.

You're just twisting and manipulating the logic so you can maintain the moral high ground when in actuality you're twisting everything.

The first problem is I'm not talking about mass slaughter. When the fuck did that become the topic? Are you saying I promote mass slaughter because China promotes mass slaughter? You're under this western propaganda where you seem to think China is some futuristic cyberpunk city on top but underneath the system is bathed in blood, torture slaughter and evisceration. Nothing is further from the truth.

When China tortures, when china executes someone, it is for crimes that fit punishment. They won't execute you if you're in a cult. They will execute you if you stole millions of dollars. The debate is about degree but the overall severity is reasonable.

I'm sick of talking to people with a misguided view of China. It's like talking to a clown. Somehow people like you are convinced that it's just blood and evil underneath.

>Not what I was hinting at.

Speak in english please, don't speak in hints. I said religions were not true, you countered with architecture. Now you claim it was a hint. Hint: don't speak with hints.

>They actually are, but I haven't articulated the reasoning fully. Nor do I feel encouraged to articulate it. If you're truly in good faith, enough has been already said for you to do your own research

No they aren't. I don't need to do research for a country I'm highly familiar with and even lived there for quite some time. I'm going to be utterly clear: You are ignorant and you are illogical and you need to do research. I'm Chinese. And I was born in the states. I know both cultures intimately, you only know one through the lens of US propaganda.

Good faith my ass. If you were talking to me in good faith you'd concede your lack of knowledge.

I don't get it - afaik you can get every single part of a gun except for the lower receiver/pistol frame without any restriction - as those parts are legally defined as the 'gun' - the rest are just replacement parts.

Even for those, you can get 80% finished parts for those - just drill a few holes, and file off some tidbits, and you get an almost factory-spec gun.

I'm no expert on US gun law, but afaik, some states even allow you to make your own guns without registration, as the law defines gun manufacturing as manufacturing with the intent of selling them.

So there's plenty of options, many of them better than making a gun with a printer.

But even all this is typically overkill, I dont think criminals go to these lengths to make their own guns, they just get them from somewhere.

It is well known that Musk primary reason to push Hyperloop was because he didn’t want them to build a high speed rail for some reason:

> Musk admitted to his biographer Ashlee Vance that Hyperloop was all about trying to get legislators to cancel plans for high-speed rail in California—even though he had no plans to build it.

The really crazy thing is you don't need to know more then basic (non Hollywood) physics to know how dump this is

1. every gram you need to send to space is costly, a issue you don't have at ground level

2. cooling is a catastrophe, sure space is cold, but also a vacuum, so the cooling rate is roughly the infrared radiation rate. This means if you are not careful with the surface of a satellite it can end up being very slowly cooked by sunlight alone not including running any higher heat producing component (as it absorbs more heat from sunlight then it emits, there is a reason satellites are mostly white, silver or reflective gold in color). Sure better surface materials fix that, but not to a point where you would want to run any heavy compute on it.

3. zero repair-ability, most long running satellites have a lot of redundancy. Also at least if you are bulk buying Nvidea GPGPUs on single digit Million Euro basis it's not rare that 30% have some level of defect. Not necessary "fully broken" but "performs less good then it should/compared to other units" kind of broken.

4. radiation/solar wind protections are a huge problem. Heck even if you run things on earth it's a problem as long as your operations scale is large enough. In space things are magnitudes worse.

5. every rocket lunch causes atmospheric damage, so does every satellite evaporating on re-entry. That wasn't that relevant in the past, but might become a problem just for keeping stuff like Starlink running. We don't need to make it worse by putting datacenters into space.

6. Kessler Syndrom is real and could seriously hurt humanity as a whole, no reason to make it much more likely by putting things into space which don't need to go there.

Last but not least, wtf would you even want to do it?

There is zero benefit, non nada.

> Why are they doing any better than any other firm then?

Any other firm, you mean like the bloated and bureaucratic NASA/JPL/defense contractor madhouse? That's not much competition.

> Why has Tesla been successful? Why is xAI pretty similar in terms of approach?
My idea has less variables than yours. It also doesn't fly with his tendency to fire people.

Your "idea" (statement) is that his companies are successful due to his micromanagement. In reality, they're successful in spite of it. Like all impactful engineering institutions, there are incredibly talented people working at the "bottom" levels of these companies that hold the whole thing together.

There's a good bit of irony here in your thought that he'd fire people that didn't agree with him or disobeyed him. From what I've heard, he lacks the technical rigor to even understand how what was implemented differs from his totally awesome and cool, off the cuff, reality adjacent ideas.

The myth of the supergenius CEO has real potential to influence investors, beyond that, the hard engineering is up to the engineers. Period. SpaceX wouldn't have gotten past o-ring selection with Elon at the engineering helm.

> Sure it might be on the device, but they would need a password to decrypt the laptop's storage to get any of the data.

In these situations, refusing to provide those keys or passwords is an offense.

The employees who just want to do their job and collect a paycheck aren’t going to prison to protect their employer by refusing to give the password to their laptop.

The teams that do this know how to isolate devices to avoid remote kill switches. If someone did throw a remote kill switch, that’s destruction of evidence and a serious crime by itself. Again, the IT guy isn’t going to risk prison to wipe company secrets.

Remember what the Luddites actually did? They sabotaged the machines that were disrupting their livelihoods. If AI is as disruptive to large numbers of workers as some people think it will be, keep in mind it's a lot easier to destroy a GPU that's stored on earth than one in space.

Anyone planning expenditures as large as a modern data center thinks about all kinds of risks (earthquakes, climate, power, etc), and so perhaps there is a premium for GPUs that are out of the reach of your median angry unemployed guy.

(yes, this is nuts, but I can easily imagine some fever-dream pitch meeting where Musk is talking about it)

> aka fancy air conditioning pumps

Yeah, pumps, tubes, and fluids are some of the worst things to add to a satellite. It's probably cheaper to use more radiators.

Maybe it's possible to make something economical with Peltier elements. But it's still not even a budget problem yet, it's not plainly not viable.

Small features and fractal surfaces are useless here.

Look for the CRI rating of bulbs that you buy. It's a measurement of how close to a blackbody spectrum the bulb is putting out, the highest fidelity being 100. Note that this is not the temperature measurement, and you can have e.g. 2700K or 5000K bulbs with high CRI.

Newer LED phosphors are typically 90+ CRI, and I commonly find 93 CRI bulbs available off the shelf.

To be fair, Trump seems to be doing more for software freedom and against rent-seeking US monopolies than any previous president. Not saying he's doing it intentionally, but he is doing it. Heck, maybe he applies that policy domestically and US software companies flourish once again without the grip of big tech and unfair business practices that starve their competition. Right to repair, reverse-engineering and modding coming very soon...

> what do you think a local manufacturer shop in the US would do better?

The post documents issues like some assembly workers stuffing so much wire into the post that not enough protruded to make a connection. I will hope that in the US the workers are paid enough that they notice/care that the result can be connected. Or the managers.

Do you want documented experiences of Chinese manufacturing repeatedly attempting to cut corners? Like substituting inferior goods to increase their profit margin even after the initial product line is running smoothly.

I ended up documenting what I found while testing different CV layouts and parsing behavior across ATS.

It’s not a tool and it doesn’t generate CVs — it’s a technical, text-first system explaining what tends to break parsing, what survives reliably, and how to make structural decisions that don’t depend on folklore or guesswork.

Sharing it here in case it’s useful for others looking into ATS behavior:

I have one of these - it's awesome, I love it and I think it's an incredible success for a first hardware product. My takeaway from reading this is that caring about building a great product made a huge difference in how your first 500 units landed. Now the next batch gets to come with all those learnings.

I'm sure there will be more challenges as well but as long as you keep focusing on the experience you're delivering, I'm sure you'll continue to get past them

I mean, the idea kinda makes sense.

But, first of all, do you really HAVE to make your admins to set this up? https://learn.microsoft.com/en-us/microsoftteams/rooms/third... It requires Exchange re-configuring, URL re-writes and client setups.

But both teams and meet can be launched from a browser. And truth to be said I'm very happy about it. I don't want Teams client hanging around on my PC. So what is the exact problem that is being solved here?

I'm actually asking. Probably there will be some use for highly restrictive networks where all of the computers are managed and software lists are approved by admins. That kinda makes sense.

Not AI but I've heard car thieves operate like this - as a loose network of individuals, who do just a part of the process, which on their own are either legal, or less punishable by law than stealing the car.

One guy scouts the vechicle and observes it, another guy is called to unlock it, and bypass the ignition lock, yet another guy picks it up and drives away, with each given a veneer of deniability about what they're doing.

So story time. About 8 years ago, most of corporate America tried to do this. It was called the ad-pocalypse. They came crawling back to SV in less than 2 months. Turns out, the correct response to an organized (politically based) pressure campaign is to tell them to pound sand.

When your customers see the dev bill (what it costs to make software that actually works and doesn't get its secrets stolen), they will do the same. But not after some LLM based disasters cause some chaos. Should make your life more interesting, no?

> The counter extermination was only 5% of Athens total population, or so historians say, so it seems like a lot of nuance was shown.

That fact alone doesn't demonstrate nuance. It's possible that 5% of the population was innocent and treated as scapegoats, or chosen randomly, or that anyone high profile regardless of guilt was chosen to die.

Unless there's data on who was actually innocent or guilty, the mere fact that extermination was selective doesn't mean it was in any way accurate.

Jews that became Muslim are not a good counter-example.

Jews who haven’t converted to Islam have been ethnically cleansed from the West Bank by Jordan when they occupied it, and this apartheid is maintained by the Palestinian Authority. Anyone visibly Jewish who enters areas under total PA control gets arrested (or lynched).

Why can’t Jews live under Palestinian authority the same way Muslims live in Israel? This racism has led to a situation where the only way the Jews of the West Bank can be safe is by having an IDF presence.

Your “fears” of Jews turning into sellers are no different to the Islamophobes who say Muslims who come to live in western countries will turn them into caliphates.
