youarentrightjr··on Data centers in space makes no sense
> What do you and them know that the countless extremely successful engineers who actually worked with Elon do not?

Did you read my comment?

"I have multiple friends in the industry, who have taken a trip through the company."

I am literally referring to extremely successful engineers who have worked directly with Elon.

I'm going to need more than a puff piece on some random Elon stan's medium page to outweigh what I've heard from my friends.

youarentrightjr··on Data centers in space makes no sense
> 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.

youarentrightjr··on Data centers in space makes no sense
> Yeah he only micromanages (look at his old blog) every detail he has time for at an extremely successful aerospace engineering company, just an ideas guy.

Have you ever spoken to someone who works at SpaceX? I have multiple friends in the industry, who have taken a trip through the company.

The overwhelming consensus is that - in meetings, you nod along and tell Elon "great idea". Immediately after you get back to real engineering and design things such that they make sense.

The folks working there are under no delusion that he has any business being involved in rocket science, it's fascinating that the general public doesn't see it that way.

> I think OP was saying hotter part -> hotter radiator attached to the part, not that the part itself will radiate significantly.

Hmm, surely the radiator can run at arbitrary temperatures w.r.t. the objects being cooled? I'm assuming heat pump etc is already part of the design.

> [1]Robotaxi. Someone just drove coast to coast USA fully on autopilot.

Where's the source for this?

youarentrightjr··on xAI joins SpaceX
Lasers, space, super geniuses, and most importantly money. You're worrying too much about the details and not enough about the awesomeness.

But seriously, why are all the stans in these comments as unknowledgeable as Elon himself? Is that just what is required to stan for this type of garbage?

youarentrightjr··on xAI joins SpaceX
> I see what you’re saying - higher design temp radiates better despite more energy overall to dissipate.

Yes, running hotter will cause more energy to be radiated.

but

These parts are not at all designed to radiate heat - just look at the surface area of the package with respect to the amount of power they consume.

youarentrightjr··on xAI joins SpaceX
> You do not radiate all the heat away from a GPU, a modern GPU can run pretty hot.

Fascinating. Tell me more.

Where does the heat energy that isn't radiated away go?

youarentrightjr··on xAI joins SpaceX
On the off chance you're sincere and not just heavily over indexed into Elon stocks:

It's trivial to understand why this is all hype if you pay attention to physics, as another commenter suggested earlier.

https://en.wikipedia.org/wiki/Stefan%E2%80%93Boltzmann_law

Assume you're radiating away the heat for a single B200 (~1kW), and the max radiator temp is 100C, you find A = ~3m^2.

So that's 3 square meters per GPU. Now if you take into account that the largest planar structure deployed into space is ~3k m^2 (https://investors.lockheedmartin.com/news-releases/news-rele...), you're looking at 1000 GPUs.

That's a single aisle in a terrestrial data center.

Cost to deploy on earth vs satellite is left as an exercise to the reader.

> Yep, definitely being scammed by not dismissing things outside my area of expertise out of hand. I wish I had your confidence about everything!

Instead you put your confidence in Elon, who has zero expertise in this area?

youarentrightjr··on xAI joins SpaceX
> Have you considered that people smarter than you think it is plausible?

I know many people smarter than me, plenty of them who have spent careers building data centers, and not one of them think this is plausible.

You should consider whether people smarter than the average investor are pulling a fast one.

youarentrightjr··on Apple's MacBook Pro DFU port documentation is wrong
> Doesn't that linked webarchive page say specifically that the ACE is a "Apple/TI co-designed USB Type-C Port Controller" If that isn't a "USB Controller" what do you mean when you say "USB Controller"? "USB controller" in common parlance means a USB host controller, the hardware that actually controls the USB signals and interfaces with the host CPU(s). They are required no matter if the physical port is type A, B, C, ... A "port controller" is something completely different, but still related to the "USB type C port" specification. It's a piece of logic (in this case in a separate IC) that handles things like negotiating PD, as well as which protocol(s) will be used over the high speed lanes etc. See the section about pin usage in different modes: https://en.wikipedia.org/wiki/USB-C comex's comment is inaccurate with respect to the commonly understood meaning of "USB controller" - while that port does have the CC lines going to ACE, the actual USB data lines go to the Apple SoC directly. This is contrasted with a different design where the USB data lines could go to a standalone IC, and that IC is connected to the Apple SoC via PCIe for example. DFU is significantly more complicated in this type of design because it requires bootstrapping and interaction with this external component.
youarentrightjr··on Apple's MacBook Pro DFU port documentation is wrong
See my response to tpmoney - not all signals in the DFU port go to the port controller.

> ChatGPT is wrong. The DFU port does go through a USB controller with firmware. [1]

> [1] https://asahilinux.org/docs/hw/soc/usb-pd/

What in your linked page made you conclude this? Your link references https://web.archive.org/web/20211023034503/https://blog.t801..., which clearly states that ACE is a port controller - this is not the same as a "USB controller".

youarentrightjr··on FBI is investigating Minnesota Signal chats tracking ICE
> The second amendment as a serious option for a regime reset button was always a fantasy. This federal government would happily take a lesson from the Chechen wars and use ballistic missiles against a rebelling city if the chips were down. Any 2A fans have their own Patriot missile defense systems? No?

If it's that easy, why did we spend 20 years in Afghanistan only to suffer defeat by goat herders holding AK-47s?

A quick review of the last 100 years will educate you on the viability of asymmetric warfare.

youarentrightjr··on FBI is investigating Minnesota Signal chats tracking ICE
> ... Did you watch the videos from multiple people filming?

Yeah, did you? Any more substantive discourse you'd like to add to the conversation?

To be clear about the word "reasonable" in my comment, it's similar to the usage of the very same word in the phrase "beyond a reasonable doubt".

The agents involved in the shootings aren't claiming that:

- the driver telepathically communicated their ill intent

- they saw Pretti transform into a Satan spawn and knew they had to put him down

They claim (unsurprisingly, to protect themselves) that they feared for their life because either a car was driving at them or they thought Pretti had another firearm. These are reasonable fears, that a reasonable person has.

That doesn't mean the agents involved are without blame. In fact, especially in Pretti's case, they constructed a pretext to began engagement with him (given that he was simply exercising his 1st amendment right just prior).

But once in the situation, a reasonable person could have feared for their lives.

> It's like designing new kinds of nerve gas, "quite sure" that it will only ever be in the hands of good guys who aren't going to hurt people with it. That's powerful naïveté. Once you make it, you can't control who has it and what they use it for. There's no take-backsies, that's why it should never be created in the first place.

Interesting choice of analogy, to compare something with the singular purpose to destroy biological entities, to a computing technology that enforces what code is run.

Can you not see there might be positive, non-destructive applications of the latter? Are you the type of person that argues cars shouldn't exist due to their negative impacts while ignoring all the positives?

youarentrightjr··on FBI is investigating Minnesota Signal chats tracking ICE
> but to think that ICE agents are going around and reenacting the opening scene from Inglorious Bastards shows that your worldview can't handle more nuance than "fascism? true/false".

Precisely.

There's no question that ICE is daily trampling civil liberties (esp 4th amendment).

But in both killings there is a reasonable interpretation that they feared for their lives.

Now should they have is another question. With better training, a 6v1 < 5ft engagement can easily disarm anyone with anything less than a suicide vest.

But still, we aren't at the "run around and headshot dissenters" phase.

youarentrightjr··on Lennart Poettering, Christian Brauner founded a new company
> This company is explicitly all about implementing remote attestation (which is a form of DRM):

Is there a HN full moon out?

Again, this is wrong.

DRM is a policy.

Remote attestation is a technology.

You can use remote attestation to implement DRM.

You can also use remote attestation to implement other things.

youarentrightjr··on Lennart Poettering, Christian Brauner founded a new company
> So your device had no user freedom. You're not doing much to refute the notion that these technologies are only useful to severely restrict user freedom for money.

Would love to hear more of your thoughts on how the users of the device I worked on had their freedom restricted!

I guess my company, the user of the device that I worked on, was being harmed by my company, the creator of the device that I worked on. It's too bad that my company chose to restrict the user's freedom in this way.

Who cares if the application of the device was an industrial control scenario where errors are practically guaranteed to result in the loss of human life, and as a result are incredibly high value targets ala Stuxnet.

No, the users rights to run any code trumps everything! Commercial device or not, ever sold outside of the company or not, terrorist firmware update or not - this right shall not be infringed.

I now recognize I have committed a great sin, and hope you will forgive me.

youarentrightjr··on Lennart Poettering, Christian Brauner founded a new company
> Trusted boot is literally a form of DRM. A different one than remote attestation.

No, it's not. (And for that matter, neither is remote attestation)

You're conflating the technology with the use.

I believe that you have only thought about these technologies as they pertain to DRM, now I'm here to tell you there are other valid use cases.

Or maybe your definition of "DRM" is so broad that it includes me setting up my own trusted boot chain on my own hardware? I don't really think that's a productive definition.

youarentrightjr··on Lennart Poettering, Christian Brauner founded a new company
> Interesting. So what did the attestation say once I (random Internet user) updated the firmware to something I wrote or compiled from another source?

The update is predicated on a valid signature.

youarentrightjr··on Lennart Poettering, Christian Brauner founded a new company
> Secure boot and attestation both generally require a form of DRM.

They literally don't.

For a decade, I worked on secure boot & attestation for a device that was both:

- firmware updatable - had zero concept or hardware that connected it to anything that could remotely be called a network

youarentrightjr··on Lennart Poettering, Christian Brauner founded a new company
> Remote attestation is literally a form of DRM

Let's say I accept this statement.

What makes you think trusted boot == remote attestation?

youarentrightjr··on Lennart Poettering, Christian Brauner founded a new company
> Sounds like kernel mode DRM or some similarly unwanted bullshit.

Look, I hate systemd just as much as the next guy - but how are you getting "DRM" out of this?

No offense, but you're simply ignorant on this topic.

https://scispace.com/pdf/a-guide-to-time-of-death-in-selecte...

This is just one of literally thousands of resources answering this exact question. There are other resources to help evaluate other potential consumption risks. There's no need to pretend that the only animals people can eat are the ones they witnessed being killed; people do otherwise, and have for millennia.

youarentrightjr··on Sugar industry influenced researchers and blamed fat for CVD (2016)
> For RFK that includes a roadkill bear.

> No, we're discussing a bear that was dead by the road.

https://www.merriam-webster.com/dictionary/roadkill

Your interpretation is wrong, and potentially disingenuous.

Animals killed by vehicles on the road are pretty easy to distinguish from animals that coincidentally died on the road.

> He found the bear long after whatever occurred did. Also, he then dumped it in central park, so even he thought it wasn't "good meat"

So your argument is that there's something wrong with roadkill because it might be afflicted with something that would make it detrimental for human consumption; now you admit that he was able to evaluate its fitness for consumption, and avoided consuming something that wasn't "good meat"?

What point are you making exactly?

Yours is the same argument as right wingers screaming "ewwww insect derived protein is gross, don't you know insects can cause ____".

youarentrightjr··on Sugar industry influenced researchers and blamed fat for CVD (2016)
> If it died due to disease

We're discussing roadkill bear. Meaning a bear that was killed on the road (by a vehicle).

It's technically true that it still could have any of the scary afflictions you mention, but that's no different than any hunted game, or any industrially farmed animal.

Barring prions or poisoning (incredibly and quite rare, respectively), all of those issues can and would be evaluated by someone who intended to consume the animal.

I'm curious if you consume meat, and if you've ever been involved in the slaughter or processing of animals.

youarentrightjr··on Sugar industry influenced researchers and blamed fat for CVD (2016)
> This is the sort of misdirection that requires the follow up question "what is real food?". For RFK that includes a roadkill bear.

What is wrong with roadkill bear? Genuinely asking.
