It's just memory mapping the peripheral.

For historic reasons (e.g. 32 bit address spaces, plus the need to reserve the space for multiple pci peripherals) it has been a narrow, movable aperture.

Resizable BAR lets the size of the aperture be chosen (which is usually chosen to allow all of VRAM to fit in and be directly accessible).

Moving 1000W of heat generation takes way less than 1000W.

Hyperscaler PUE (which includes cooling, power conversion, etc) is typically 1.10-1.15, so multiply 1.5% by 1.1.

The person you replied to already mentioned cooling and multiplied by 1.67 to cover ancillary uses.

I think mechanical / electronic intuition are important, and they come from tinkering (especially at younger ages).

Sure, being able to do math and detailed analysis are important. But having a good guess on step 1 is important, too, to narrow the search of huge design spaces.

I think we've all experienced different kinds of engineers. The one you trust to do a month-long trade study with deep mathematical reasoning is usually not the one you trust to just know a plausible path forward. And we need both.

I operate a small fleet at my school:

* 1x Prusa XL Gen 1 with 5 toolheads * 1x Prusa Mk4IS * 1x Bambu Labs X1C with multi-material * 2x Voron 0.2 * 1x Sovol Zero

My experience: the typical higher-end printer runs out of the box and runs hundreds of hours (or more) between maintenance beyond wiping the plate down, occasionally greasing the rails, and blowing little plastic bits out of the enclosure. Every year I end up doing a few hour significant maintenance job on about one of the six printers.

But then there's lemons. That Sovol Zero is terrible and has been down more than it's been up, because of something in the extruder assembly. It also came with a defective camera and needed it replaced. I need to decide whether to rebuild all that with many hours of labor or just get rid of it.

I mean, on the one hand, manufacturing has grown near-continually for those 70 years, and its demand for labor has reduced. So, it's not like you're wrong.

At the same time, our production of lower value, commodity-ish things has indeed shrunk rather than grown with population of demand. That manufacturing expertise is more concentrated more on higher value (aerospace, information technology, etc) things and less on fasteners, bulk materials, or extrusions.

We are not vertically integrated in the way that China is.

Is this really true? Or are we counting like the games kids made in a computer lab somewhere.

Or there's this 87% number, but it's based on "no longer a legal way to buy it," not that it's not archived/preserved: https://gamehistory.org/87percent/

> Or are we counting like the games kids made in a computer lab somewhere.

We don't have to count amateur projects but the commercial releases in the US is not the entirety of the gaming history. There are other countries with their own rich gaming histories and other platforms (e.g. browser, mobile) that don't get the same attention as American releases for PC or popular consoles.

I cannot play a single game from my childhood, they were early flash games "for girls" and they were not in English. Nobody archived those.

I don't think anyone expects nvidia to "sink". We're concerned that competitive pressures and possible reductions from sky-high demand could make it really hard for nv to justify or maintain their current valuation.

That is, revenues may be unusually cyclically high.

It's going to be hard for frontier labs to keep spending at this rate without starting to make money. And even if they do, lower cost alternatives will likely impact at least to -some- extent how much of that revenue nv gets.

Have you ever checked out the beta on Nvidia stock? Not to mention its surprisingly sane P/E ratio?

Compare and contrast with Tesla.

I know the P/E isn't completely nuts.

It still prices in revenue growth.

It is possible that nv maintains an absolutely dominant market position and total amount spent on GPUs continues to rise.

It's also possible that either of these things doesn't happen.

That doesn't really have anything to do with what I said.

It's not like you can allow kids to shoot pellet guns out of a car indefinitely in a metro without substantial risk of something going wrong.

We need to (be able to) trust the police to not escalate irresponsibly and to deal with situations with nuance. Declining to escalate to authorities because we're scared of what they may do is not great.

Believe me, without the internet we can still teach.

We'll be pretty annoyed that we can't project the video that we think scaffolds today's science lesson best or show the approved choreography for the school play.

And our office staff will be annoyed that we suddenly are all running attendance to the main office old-school.

And students will take a few days to adjust to writing down homework in their planners again.

There are offline wireless hdmi adapters, this is a solved problem. Just have to have the videos pre downloaded or offline available

Sure. 99% of teachers don't know yt-dlp or use things like that, though, so you can expect minor disruptions in a lot of rooms.

But, c'mon, we have complete power outages and still address our curriculum.

We just dont have the technology

There's an infinite number of possible math problems, but the things that make these open problems worthwhile is they're interesting to people who have worked in related areas.

They're good to give to new mathematicians, and they're good to help humans understand the shape of the problem space and relative difficulty with the tools we have.

Cheesing these problems with LLMs gets rid of both the training benefit and our ability to create good related problems. There's an aesthetic part of this, too, that LLMs do not capture.

This kinda reminds me of the guys who decided to industrialize digging up dinosaur fossils, in order to feed the dinosaur fossil collector market. They were amazed that paleontologists were so "inefficient" at finding and digging up dinosaur fossils.

But from paleontologists' perspective, they go out looking for dinosaur fossils when they have questions that digging up a fossil may answer. The metric they're focusing on isn't tons of fossil mined out of the ground, it's a developing understanding of extinct life.

These open problem solutions often reveal tighter bounds on prior conjectures. Even if the solutions produced are far from elegant and only machine verifiable, we do learn new information. But I agree that just like writing prose and code, brainstorming frontier math proofs is a perishable skill
