Parallelism with the computing units in GPU permeates the entire computing model. For the longest time I don't get how partial derivative instructions like dFdx/dFdy/ddx/ddy work. None of the doc helps. These instructions take in a number and return its partial derivative, just a generic number, nothing to do with graphic, geometry or function. The number could have been the dollar amount of a mortgage and its partial derivative is returned.

It turns out these functions tied to how the GPU architecture runs the computing units in parallel. The computing units are arranged to run in parallel in a geometric grid according to the input data model. The computing units run the same program in LOCK STEP in parallel (well at least in lock step upon arriving at the dFdx/dFdy instructions). They also know their neighbors in the grid. When a computing unit encounters a dFdx instruction, it reaches across and grabs its neighbors' input value to their dFdx instructions. All the neighbors arrive at dFdx at the same time with their input value ready. With the neighbors' numbers and its own number as the mid point, it can compute the partial derivative using gradient slope.
Tesla was founded in 2003, Rivian in 2009. So Tesla took five years to start Roadster production, while Rivian has taken 12 years until first customer deliveries. Maybe Rivian will ramp faster. Sam Korus tracks the numbers and so far Tesla is ramping faster than Ford, making it the fastest ramping car manufacturer in American history. I wouldn't be surprised if some Chinese companies could go faster. It is much faster than what Toyota did. They are very methodical, which is why they have almost zero pure EV sales.

Not sure how is this possible. Automatic cars almost always require You to push brake constantly if you not driving. You can't turn car on without pressing brake, can't change to drive mode from parking state without pressing brake. There should be something very broken in Toyota case.

Yes, but if their profits stayed consistent at current rates the stock price would be quite high compared to other companies. It's price-to-earnings ratio is 408, meaning it would take 408 years for it to buy all its outstanding stock just from earnings. By contrast Ford's is 16 and Alphabet's (Google's) is 29.

The 408 ratio is justified by the assumption that earnings will be a lot higher in coming decades.
TFV says that key metric is ratio of output energy over input, Q. Q> 1 and you have generated energy.

TFV picks apart reported successes by fusion experiments that say they have Q ~= 0.7 when in fact they are reporting the ratio of energy delivered to plasma (laser cost only) over heat measured (not electricity).

TFV says actual Q values are closer to 0.1 or 0.01.

Yes, that's silly of them to hype. The question is who is fooled. Do policy makers know? General public? The community? Sometimes context matters when reading tech papers but at any rate honesty and clarity matters.

Indeed, and by far most of the world doesn't even have any "local zero-waste shops"... in much of the developing world the amount of plastic waste the average consumer produces is still rising and nowhere near peaking, and the consumers there are still seeing this as a sign of their increasing prosperity rather than a fundamental problem.

As a somewhat traditionalist physicist, and having grown up around university campuses, I love university libraries, and probably use them more than most scientists.

It was a bit of a revelation to me when my partner, a historian, casually complained about the limits on simultaneously checked out items being a nuisance. Until that point, I had always assumed that the usual limits for scholars at university libraries, often over 100 books, were just there to prevent extreme abuse, not with the expectation that anyone would regularly reach them.

Aaand we're back to terrible incentives. You can't force people to do things that don't have incentives. Even the Soviet Union had incentives. The more you mandate regulation, the more people will find ways around it, either by finding creative ways around your regulations or just moving to other nations with more friendly policies (e.g. China, Europe). The only regulations that work are the ones where peoples' incentives are aligned with what government wants to achieve.
You could nearly double your range by buying two model Y’s it would give you around 600 miles — a much better price, and theoretically you could tow charge one and charge it, so it’s not out of the realm of possible.

Except that in some cases, the automakers are not using a CPU with external interface hardware, they are using microcontrollers similar to the PIC series, example here: https://ww1.microchip.com/downloads/en/DeviceDoc/40300C.pdf (Note, I'm not suggesting they use these exact chips, this is just an example of the level of onboard integration that is available for micro-controller chips).

Single chip system, with built in analog comparators, timers, signal capture and PWM generation module, serial UART, etc. I.e., a whole "system on a chip" with the external world interfaces already built into the chip. Changing one of these for an ARM CPU with external analog comparators, timers, PWM modules, serial UART's, etc., is a redesign effort, not just a "change the chip" effort. If the clock speed possible via the internal clock oscillator is sufficient, then this chip needs only +5V and ground (plus programming) to be able to interface to and control some external analog or digital equipment.

Here's a nice article [1] on underwater sound in extreme storms, note in the referenced paper [2] they managed to deploy a hydrophone under 10 m waves and 40 m/s winds! This type of research is largely military funded, not for its direct applications but more because sound is so fundamental to everything a navy does. There are also civilian applications for measuring waves, wind and rain, either in extreme conditions like [2] or where a surface buoy is impractical (e.g. in locations where surface buoys tend to get stolen or broken). It's definitely a case where one person's "noise" is another person's "signal". I too am a bit surprised saildrone didn't have a hydrophone on their rig, maybe they did but the sound is not so interesting for the press release.

The solar system is mostly empty space, which is neither warm nor icy. The Sun warms things; but it doesn't warm objects at Saturn distance that much.

I think Rivian will take the startup approach and pack as much density into their battery, even if it means sacrificing a large chunk of their margin.

All of that is fine for somebody designing for a million-unit SSD, who doesn't need to read any of this, and for chip vendors selling to that person.

But for each such somebody, literally thousands are stuck with whatever chip purchasing says they can get cheap enough off the shelf. Those chips will be exactly the ones that somebody else ordered 100M of without considering for even a second what the thousands of others whose experience they dictate need.

And, it remains a fact that none of the RISC-V MCU chips I can buy off the shelf have any of the B extension instructions implemented.

Unless and until we come up with a different economic model for social media, we'll always have Facebook (or Twitter, or whatever successor toxic social media site comes next).

Plenty of people here on HN have argued that the real problem is centralization, and I agree. Take whatever specific issue one might have with FB -- let's say disinformation, for instance. We have all these debates about censorship vs free speech vs accountability etc. But in fact, if FB wasn't the behemoth it is, much of this would be moot. In a world where there were _only_ smaller, more niche social media sites, fears around things like online radicalization would be much less, and any well-founded suspicions of actual criminal conspiracies would lend themselves to much more targeted warrant-backed investigations rather than privacy-destroying giant electronic dragnets. And if this example doesn't work for you, pick another one and think through how a world of smaller, less influential sites would change what you see as the problem with social media.

But you can't brute force your way to that world -- that's pushing against a very strong current. So long as the economic model is to create a large, targetable advertising market, you're going to have very strong incentives for centralization and invasion of privacy.

Contrast this with non-digital social hubs -- say, a pub. People come for the socialization, but the actual product being sold is food and drink. Social space becomes a side effect, one that complements and enhances the business model (a pub with a reputation as a good place to meet friends gets more business), but the business model isn't data-mining your audience.

I think a social media network that focused on extending offline hubs into social spaces, where the economic model is attracting an audience to gather and chat and then _selling them something_, would mitigate the incentives to centralization and invasion of privacy. We need to tie social media to the selling of actual products; users need to be customers, not the actual product.

The talk of 'red-pilling' and 'those women knew what they were getting into' in the comments give me heebie-jeebies.

Care to summarize the main points for me?
I think it's because the founders were engineers, but more than that, engineers who actually worked for someone else first and also had another company before Netflix. So unlike say Facebook or Microsoft, the company culture was created by someone who has actually been an employee before.

Also unlike a lot of the other tech companies, the salaries of the engineers aren't their biggest cost -- content is. So they don't take as big a hit on their stock price or profitability when their engineering costs go up because they are dwarfed by content costs.

And lastly because they believe that overpaying for talent makes sense in the long run because then a lot of the best talent wants to work there, so they can get paid a lot and be surrounded by other people who like a culture where poor performance is rewarded with a big severance.

I won't lie, the culture isn't for everyone. I personally enjoyed the pressure of having to constantly perform, I felt it made me do better work, but not everyone is like that.

It's incredible how acceptable seems the idea to ingest all kind of unusual stuff just because "if there's no research against it then it's fine".

The food chain is an abstraction that describes the natural world, not a moral agent any more than the water cycle is. Wild animals predate in the wild, yes, but they aren't moral agents. Humans are able to reason about our own actions and more importantly we can live and indeed thrive on a plant-based diet. So since there are ways to get our food other than killing other thinking, feeling, suffering individuals, we aren't forced to do so. We just choose to inflict incomprehensible amounts of suffering on animals not out of necessity but because we like the taste of cow milk slightly more than we like the taste of oat milk, or we love the way their flesh tastes, and would rather eat it than cook a plant-based meal.

We inflict billions of lifetimes of misery and torture on creatures with their own desires and will to live, who feel suffering and pain just as much as we do, in service of an utterly unnecessary and trivial benefit, that while we could live incredibly well, even healthier and with less impact on the environment on a plant-based diet, we like the taste of their flesh and excretions too much to choose oat milk and tofu at the grocery store.

Yes it is wrong! Future generations will look back at our time as with disbelief that we behave like this.
Wow. That was a really long wait for some really lame popups.
> Consciousness belongs to the mystics today, by default, because science can not claim it.

Science doesn't yet have an answer, but that doesn't grant the mystics any credibility. There is no 'by default' when we don't know. I'm reminded of a Dawkins quote:

Lecturer: Scientists answer questions of 'how'. If your question is 'why', I refer you to the theologians.

Dawkins: Why the theologians? Why not the gardeners?

(Trivia: If I recall correctly, Dawkins didn't actually give this response, he thought it up far too late.)

> There isn’t something we can hold and point to saying “this, this is what the mystics call a soul.”

That isn't a game-over, though.

The same goes for information processing, but we're fairly confident in what we call a 'computer'.

You can't hold a center-of-gravity, but we're able to reason about those pretty clearly.
Not OP, but I probably wouldn't either. Mainly because I shop on Amazon, and don't want that data harvested and shoved in my face.

AMZ already does "helpful" things like recommend pants extenders when you buy a size down then a size up.

You were talking about why Electron/Javascript/Node.js rules all. I'm not aware of any web browser implemented in those technologies. I know Electron is based on chromium, meaning they used a browser to implement it, but I am talking about the other way around ie implementing a browser in Electron.
"This wouldn’t be needed if they weren’t mandated to pre-fund their retirement accounts"

Retirement account funding is a cost of employing today's employees. It should be paid out of today's revenues.

If not, you could easily end up in a situation where your retirement benefit expenses exceed your revenues (let alone profits) and you have no way to pay.

This has been a fumble of communication by the fusion science community. The window for fusion power being a saving grace from climate change passed decades ago yet it has been the claimed raison d'etre for the research.

The important thing to note is that even though all climate projections end after 2050, the world does not. Better late than never. A carbon-neutral, virtually-limitless fuel, on-demand baseload energy source will still be handy even if it's "too late to reverse climate change". It will likely have a longer term of being handy than than the internal combustion engine will.

The argument this video makes at the end about "needing to spend research dollars wisely" is the exact thing the fusion researchers fear when overselling the state of the art to the public. They've been continually defunded and in spite of that still make progress. If they didn't tell the politicians what they wanted to hear do you think any fusion program wouldn't be mothballed by this point? The reality of the long-term value of the research should be enough.

We, as a society, can and should afford fusion energy research. We can also afford solar panel research, energy storage research, scaling up of carbon-neutral energy sources, and still have plenty left over to address aging infrastructure and wealth inequality. The issue is how the effort of society is actually being spent is not really beneficial to society. Whether we fund fusion research or not will not change that. Fund the research.
