> What I do know about ARM sucking is that the whole board design makes each product need a customer kernel more or less. Which is why we still don't have a "Linux for your phones". What I've read about RISC is that it's going to be roughly the same: encourage a lot of co-processors which mean custom boards to me and probably custom kernels.

FWIW, this has nothing to do with the ISA per se, and particularly absolutely nothing to do with whether the ISA is RISC, CISC, or something else.

The problem is that like so many other embedded systems, ARM systems don't have peripherals which are discoverable at boot, hence all that has to be hardcoded (or specified at boot via devicetree) into the kernel (e.g. the interrupt controller is model XYZZY and is accessible at address 0xBEEF). So you end up with a kernel binary that works only on a specific board.

The "server-class" ARM systems adhere to something called SBSA which is a specification incorporating things like UEFI, ACPI, PCIe etc. The end result being that SBSA systems can use a common distro kernel just like x86 systems can.
Reminds me of seadragon images circa 2006, which was, among other things, rolled into silverlight as 'Deep Zoom' images. There isn't much to show for it these days, but for an older opensource js implementation [1].

>He is not a neutral actor

Given that we're talking about something that's practically harming the entire population of this planet there are only two groups of people. The one's that get sick from it and get rich, and the one's that just get sick, so I think it's fair to say the number of people who have any reason to be neutral actors is 0.

x86 and ARM is what RISC-V designers frequently compare to in their own documentation. Likely because those are well known architectures.

But your argument doesn't really make any sense as ARM is a frequent choice for this kind of things. In fact is one of the main competing CPUs considered by Nvidia. ARM is widely used in embedded system. That it became a desktop CPU is a fairly recent phenomenon.

Esperanto Technologies use RISC-V both for general purpose processor and specialized coprocessors.

Anyway the whole point of RISC-V is to be able to span from small embedded systems to super computers.

> I did include the microWatts link in the post above.

I cannot find any quote on number of transistors it uses or comparison to other designs. Given that it is supposed to implement the IBM POWER ISA v3.0 which is quite huge I don't see how you can get the transistor count below that of RISC-V while still having decent performance.
The actual study is here [0] and the abstract and introduction do a much better job of describing what the study is actually about.

I encourage you to read at least those before you dismiss the research and its real-world applications.

TL;DR: The purpose of the research is to try out a new way of figuring out which sound is going into the user's ears, so that it can be cancelled out. Current methods work for lower frequencies but not for higher frequencies.

They "cheated" because they're testing one component of the system and the "cheating" component is immaterial to the research they're doing.

> Just like Tesla, a farmer can't promise to produce vegetables for less than the cost of fertilizer. Based on the foods that the world prefers to eat, it's just not feasible.

Actually, they do: subsidies distort the hell of out the price discovery mechanisms in Markets. At no point in time can a farmer sell a 1lb(~1/2Kg) of tomatoes at the hieght of season for for $1 or less, much less in the off-season. And yet they do because of the distortions in correctly pricing the inputs, transport and labour as a result of wanting to remain on the crop insurance and subsidy program.

This is seen the World over in various ways too, in the EU farmers are paid to let their fields go fallow and orchids entirely neglected for seasons; it's one of the biggest reason why Farming as a profession has an average age of 60+ World wide as any younger person not born into the Lifestyle or from a Legacy Farming family will quickly see how impractical it is to operate with this system in what amounts to near subsistence levels of poverty. As an outsider going into the Industry for culinary and ecological activist reasons it's incredibly daunting when you realize that in 100 years we created a system in which less than ~2% of the World's population feeds the ~98% and how fragile this system is and how much of a miracle it hasn't blown up in our faces long ago.

It's maintained by fanciful economic machinations and make-believe accounting created by Nation-states to essentially keep a slave labour class in place and avoid peasant revolts due to mass hunger to the detriment of everyone--and that often breaks down, see EU dairy farmer protests in 2012/13/20, and the widespread Indian suicides in the early 2000s and now the farmer revolts happening in New Dehli. Not to mention the amount of subsidies there are for multinationals to sell processed junk into the Market and sold to children school programs at an inflated prices that have resulted in lots of disease and have actually made the average population shorter: a possible inference and consequence of undernourishment due to consuming nutrient deficient food.

The Tesla model, while only slightly relevant due to State and Federal subsidies for EVs, is not painting as good as a picture as an analogy for the reasons you think if you have an understanding of either or both Industries: I happen to have worked in both.

But suffice it to say that up until recently (Federal subsidy of $7500 expired in 2019) in the US where most Tesla deliveries take place--specifically CA-- and where most of the fruit in the US is grown in (Central Valley) it is safe to say that EXACTLY both of those things happened to a certain degree.

"And the Roman Empire - which was a very effective nationalist war machine, but utterly barbaric ethically - was very consciously echoed by the British Empire."

Actually, I would say that the closest thing you have to R.E. today is the European Union, sans the military might, of course. For all the glory of the Roman legions, it is often forgotten that the Roman empire was a common market first and foremost. Without the economic ties, the empire would have been much more fragile from within.

And the EU of today resembles that ancient structure quite a bit. A huge amalgamation of a babel of nations with a shared citizenship, unification of various laws, regulations and standards so that Portuguese butter is not that different from Finnish, a lot of internal trade reaching even the most outlying extremes of the continent, a conscious building of a pan-European road network, even the original treaty establishing the European communities was signed in Rome.

Interestingly, having semi-hostile Asia Minor (Erdogan) and having almost no control over North Africa is an obvious kind of security problem for the EU, which any Roman general would immediately point out. A secure southern border would be the almost impassable Sahara, not the Mediterranean Sea.

Shameless plug, here's a "30 random good HN posts from the past"-reader I made just yesterday: https://thn.rakhim.org/
Coming from the VFX field, I think that point is pretty far off still. Even with current gen offline renderers running on renderfarms, we're left doing cost-benefit analysis on rendertime vs. quality issues. (Noise being the big one). Real-time, fully generic, photorealistic rendering is decidedly not here yet, and I seriously doubt it's around the corner, either.
Same thing on Android, it was removed from the play store. Luckily I had a copy of the .apk on my old phone and could copy it over. It's my main source of consuming and interacting with HN (including writing this comment).

Yep, this was what 2020 felt like, mostly.
In countries like India we don't really have too many consumer protections. Apple tends to operate similar to a criminal enterprise - they sell defective products / products which become defective after barely any use.

I bought the 2015 Macbook Pro which developed the "staingate" issue. In first world countries, I hear that Apple replaced the screens for customers for free (I'm not sure if this is true or whether it's astroturfing). There is no such system here. Both speakers in this Macbook developed tearing and are no longer audible. Other laptops - Samsung, Lenovo, etc. in my household have worked perfectly. One laptop developed an issue with the keyboard, which was replaced for $50.

I received Airpods as a gift this year in February. One earphone stopped working within 8 months. Apple told me they weren't going to do anything about it. I must have used them about 20 times total. I also own knock-off Airpods. They work perfectly.

I follow Louis Rossman's YouTube channel where he opens up the devices and showcases the various corners that have been cut in the manufacturing process. He also exposes the unethical behaviour of the Apple "Genius" employees who overcharge customers for simple repairs. In one case he just plugged a loose connection back in and charged the customer for 20 minutes of labour whereas Apple said it would require a screen replacement for roughly ~30% of the cost of the device.

Repairability is becoming near impossible with these products now. At one point in time you could salvage together parts from dead devices to gather spares, but now Apple is working on technology to ensure that parts from different devices will not be compatible with each other.

Without legislation they will continue to operate like this with impunity. If enough key markets push for something like "right to repair" there is a small possibility that something will be done about this, otherwise the way things are headed, there will essentially be no accountability for cases like this.

I would not be surprised if there will come a point where they make devices stop working if you open them, and only they can restore the device back to a working state.

I seen many indie games made with Unreal Engine or Unity that have terrible performance in rendering a simple level where a AAA game like Tomb Raider will use less resources and have 10x more details. So when the hardware gets so popular that indie developers can deliver similar graphics as AAA games today the AAA games will still do it 10x better by having engineers optimizing things.

VR/AR will continue past 8K to 16K and beyond. 240+ Hz will be desirable there too. We're going to need to keep squeezing the hardware for all it's worth for the foreseeable future. I doubt there will be "sufficiently powerful" hardware to drive that kind of workload without heroic optimization work within my lifetime.
Can be is not is. One can rewrite that in a functional not implace style. Less so for a language with a c like call stack. Which is why the op wrote it like that instead of using tail call recursion.
I was a big fan of the original zoomquilt. This one is even more incredible. It gives me the same vibes as The Garden of Earthly Delights, by Hieronymus Bosch.
IMHO the privileged point of view is yours, we are not the only inhabitants of earth looking up to the sky in the night, many animals rely on it to navigate/migrate. Many humans still don't know what is the internet and enjoy to look at the sky for pleasure and necessity. For sure when someone thinks it is ok to change the earth's night sky, just to be able to work from home, avoid to go to the bank, to see cat videos, memes and fake news, is by definition a privileged lazy guy.
Unless you live in a totally closed eco-system, you share the same water, air, fauna and flora as anybody. So you should be concerned as well.

> There will come a time in which hardware is sufficiently powerful that one no longer needs these tricks to create top graphics.

I deeply wish this were true. But it doesn't seem likely to me.

Games are real-time. And frame rate expectations are getting higher (60, 90, and even 120Hz) which means frame times are getting shorter (16ms, 11ms, 8ms). Rasterization is likely to always be faster than raytracing so the tradeoff will always be there.

Pixar movies look better and better ever year. The more compute they can throw at the problem the better pixels they can render. Their offline rendering only gets more complex and higher quality every year. It's so complex and expensive I'm genuinely afraid that small animation studios simply won't be able to compete soon.

Maybe raytracing will be "fast enough" that most gamedevs can use the default Unity/Unreal raytracer and call it a day. But imho the author is spot on that AAA will continue to deeply invest in highly complex, bespoke solutions to squeeze every last drop and provide competitive advantage.

They may be just didn't find a way to make ads better with payments APIs but seriously, I think the only reason why google didn't get into payments is the customer service burden also, why would the company which depends on ADs wouldn't want to see the result(purchases).

There's nothing pulling so much power at startup that both the adapter and battery are required.

Even older MacBooks would boot with the battery disconnected (in some sort of safe mode).

https://osxdaily.com/2019/06/14/how-boot-macbook-pro-without...

Newer ones likely wait to check the battery properly.

I've not come across any laptop or Android smartphone that wouldn't power up without a battery.

However, I do not have any experience with USB-C powered laptops, those might be different seeing as they need to negotiate power first.
This is a great idea, I always struggle getting Bezier points to look natural. Will definitely play more with this, looking forward to the future posts!

This won't change until companies are fined sufficiently to prevent this. More importantly, those responsible must retrospectively face prosecution and jail time.

They "cheated" because they did the easy part, and the "other component" has no known solution.

What they're handwaving away is the real problem. The reason why current methods work for lower frequencies and not for higher frequencies is that your microphone, emitter, and ear all need to be enclosed within a volume << the minimum wavelength you can handle, to eliminate sound field and propagation time effects and let you treat the noise cancellation problem as a point problem in space.

Once you put the ears in open air and the emitters away from them, the problem isn't figuring out the sound that's going into the users' ears, it's figuring it out in advance. The ANC speakers have to send the complement signal before the original signal arrives at the ears, so they both arrive coincidentally.

In other words, the "missing part" to make this research work is time travel (if you use their sensing technology as the only input). Or maybe full-volume sound field sampling and characterization technology (if you don't). Neither of which exist, and which are orders of magnitude more difficult than this research.

The handwave part is "The constraint of the possible locations [of microphones] would affect the control performance and this remains a topic to be further studied in the ANC community."

Yes, it would completely destroy high frequency performance, which is what they were trying to achieve, in anything but lab scenarios (such as the sound sources still being loudspeakers and the microphones being directly in line between them and the user). Real world noise doesn't come from loudspeakers, it comes from all around you. Good luck using distant microphones to compute the expected sound at a user's ear in advance, with any kind of accuracy in the high frequencies.

At best I imagine they could achieve adaptive cancellation for a set of slowly moving pointlike sources in an otherwise simple room, with a number of microphones greater than the number of sources. It's like RF MIMO systems. But again, this is orders of magnitude more work to implement, and real world constraints are going to kill your high frequency response. And for larger sources - forget it. You just can't characterize the transform for that. Not enough dimensions in your input data to solve for it. So anything mechanical, stuff where the noise isn't coming from a literal speaker with a 1-dimensional input signal - nope. As the uncertainty and source size grows, your high frequency response goes down the drain.
I don't get the joke.
Multiple is not the same as all. Once a civilization colonizes a handful of solar systems, it is essentially impervious to any disaster. Further expansion produces diminishing returns. There is no resource which can justify the cost of interstellar travel, and any civilization capable of making technology on that scale will have to be social enough that a latency of years to centuries in communication with the civilization's core would be a major disincentive. Even if there were a brief exploration phase when everything was new and uncharted, there would be no reason to maintain all those colonies indefinitely. A civilization inhabiting a dozen star systems all within a few lightyears of eachother would not be significantly more detectable than a single planet civilization.

How long does it take to render a frame from a Disney's newest CGI movie release? 12 hours? So yeah, once the hardware improvements bring down that 12 hours to 16 milliseconds, then we won't need the hacks...
