>For operating conditions of the reduction at 1500 °C

Unfortunately, this figure is fatal to any solar-thermal project. While the color temperature (hence theoretical limit) of sunlight is a blistering 5000 K, real concentrators achieve much less. For practical purposes they are divided into two categories:

- single-stage concentrators, which employ a single heliostat (array of mirrors) or parabolic trough to focus sunlight onto a collector;

- double-stage concentrators, which use a second mirror to achieve very high temperatures.

The largest double-stage concentrator ever built is the Odellio solar furnace operating at just one megawatt:

https://en.wikipedia.org/wiki/Odeillo_solar_furnace

For practical purposes in the foreseeable future, single-stage concentrators are the technology of interest, currently representing around 7 GWp of installed capacity around the world and growing rapidly. These reach a maximum temperature of about 550 C, which is just barely enough to run the copper-chlorine cycle, but not many of the more fanciful solar fuel cycles. Some single-stage "dish" systems reach 750 C at much smaller sizes (the startup that was selling this pivoted to batteries [1]). Some research has proposed ways to boost power tower temperatures to as high as 800 C [2].

But 1500 C? In a single-stage system? It would require a level of accuracy that just isn't available. Such a system requires a solar concentration ratio of around 2500 suns [3]. This is extraordinarily difficult, because the sun subtends a finite angle for an Earth observer and hence reflects off a mirror with a significant divergence; furthermore an ideal reflector is not planar but slightly curved, and every mirror on a flat field would be curved slightly differently, creating impossibly difficult manufacturing issues. Real-world systems hover around 500 suns, with 1000 suns being a commonly stated practical limit [4].

I doubt it's beeper. After all they contribute a LOT, they employ tulir who maintains most of the bridges which are all offered as FOSS. Even though they compete with Element One a bit (not really because they're twice the price and offer way more bridges) they can't be considered freeloaders. Perhaps they don't contribute much to the core service but the bridges are really important to the ecosystem.

The governments? Perhaps. But they're high-profile clients that give matrix a lot of validity. Also I doubt they write much code they don't open source.

It's a form of limited voting, with both approval and disapproval votes. In a unit, maybe there are 20-40 "candidates" and you are given four votes, two up and two down.

Completely agree. Personal information should be a liability to corporations. It should actively cost them money to know anything at all about us. They should be scrambling to forget all they can the second we're done transacting with them.
None of what you’re saying changes anything or conflicts with what I’m saying, near as I can tell?

Of course the rules are there to maintain the status quo?

Do you think they don’t know that?

The rules won’t change until long after it’s started to be unsustainable either. That’s normal.

The only people who are going to pre-emptively change the rules to make things better are the folks who are competing to be the next ‘big thing’, not the already big thing.

The already big thing is trying to not lose what they already somehow got. They’re going to be fundamentally conservative unless they’re very risk tolerant, which is rare.

>Western countries do not have blasphemy laws

That's arguable and the West's oppression can be subtle but real.

Look at the people who suffered trying to expose the Catholic church's history of protecting pedophiles. Look at the people who suffered exposing things like Scientology or other cults. Look at people who have lost their jobs for speaking out against certain religions or religious groups or religious practices. Losing a job in the USA can be a death sentence if one can't afford health insurance. At least Thailand has socialized medicine.

The state doesnt protect you from this, they tell you that under civil charges or firing if you cant afford an expensive lawyer to fight these wealthy organizations, then too bad.

These laws and practices are defacto anti-blasphemy laws and just as oppressive, if not more so, than what is allowed in Thailand.
OpenAI showed it in 2017 with the sentiment neuron (https://openai.com/research/unsupervised-sentiment-neuron). Basically, the model learned to classify the sentiment of a text which I would agree is a general principle, so the model learned a generalized representation based on the data.

Having said that, the real question is what percentage of the learned representations do generalize. For a perfect model, it would learn only representations that generalize and none that overfit. But, that's unreasonable to expect for a machine *and* even for a human.

Maybe we just don't know. We are staring at a black box and doing some statistical tests, but actually don't know whether the current AI architecture is capable enough to get to some kind of human intelligence equivalent.

From my experience in automotive, the ISO standard is against dynamic allocation if your system is classified high enough in terms of their safety levels.

As an example, we weren't allowed to use the C++ string class, and had to find a "safer" string class for C++.

(Not sure about MISRA - most of my experience is with the ISO standard, and MISRA is not mandated by it).
Treating this as an example of a question we'll have to deal with more...

In this example, I initially thought that the 2 fake images of monks I saw were cool and humorous. But then I learned that the portrayal actually bothered those people, which took much of the fun out of it. So probably I either wouldn't make images like those of monks, or if I did for some private amusement, I wouldn't distribute them.

Other people, once they're aware that it's upsetting, might also decide not to do it.

We collectively already have various values about rudeness and being considerate.

These values will come into play more with AI-generated fake images/videos/audio/etc. and with the Internet to distribute them globally.

What I think is going to complicate this is both:

1. Being widely connected by Internet, across many cultural groups, means that behaving with goodwill is harder, because there's a lot more things to know about, than just the conventions of our city.

2. Recent "Internet culture" has had a lot of sociopathic behavior in general (e.g., many Twitter behaviors), plus the relative minority of influencers often get status through sociopathic behavior. So we aren't surrounded by conspicuous examples of good behavior that would help intuition for what's good and bad. Relative to how we see ourselves, or how we aspire to be.

(Though we do have fashionable mimicking and posturing, which right now is used as weapons in toxic behavior, and often without much apparent thinking. So, for example, we might see ourselves as helping those in need of help, which I think is very admirable. But the Twitter behavior we see as examples is mostly about scorched-earth attacking any peep from anyone that sounds like an idea we've been told is one of the officially bad talking points. Without individually thinking about it beyond that -- neither about what is good or bad, nor about how we respond to it, mostly just mimicking fashion we observe. This not only makes for a toxic environment that's vulnerable to manipulation/co-opting, but can make it harder to respond according to our believed values when presented with a new situation. Like the many implications of what will happen when every schoolchild can make and distribute deepfakes of anyone.)

On the other hand, maybe if they are efficient with their ads, perhaps they have more budget to put into the product instead of the marketing.

I would rather buy a product that put 90% of the budget into the product and 10% to ads as opposed to 50%/50%.

But I'm sure, they will first A/B test this with real actors to see what the results are before they decide on the course.

The roots of all this stretch back decades. Whereas the US allowed unhealthy foods and cigarettes to advertise using cartoon characters, and still do, other countries introduced strict prohibitions on such activities. While Joe Camel is a thing of the past, Ronald McDonald is happily sheparding a pediatric obesity crisis.

Which is all to say none of this is the result of a “broken” system, it’s the result of a well designed evil system.

Technologists weren’t “trying” to build these systems, but happily devoted their lives to advertising without knowing jack shit about the industry or its effects on society.

Any solution will require targeting multiple sources of cost. As you point out elsewhere, R&D is a big cost driver, but profit seems comparable [1]. Moreover one does have to wonder about the various sources of that R&D cost, I'm not an expert but it would seem to me that issues like "evergreening" would inflate development costs unnecessarily.

I think reviews in general suffer a lot from the commodification that's happened as the gatekeepers have conglomerated.

There are no spoilers in the article. It's less revealing than the trailer.
In practice the arbitrary sizing of basic C integer types (int, long, etc.) has proven to be extremely error prone. Basically it's virtually impossible to use them correctly (except in small examples). You don't get any portability benefits because it's too difficult to write code that is actually portable across word sizes, and you get extra bugs when things don't behave like you expect. There's basically no upside.

It's much less error prone to use fixed size types, especially since approximately all computers are now 32 or 64 bit.

I once lost hours on an Arduino project exactly because of this. I was using the SD card library, and there was an infinite loop bug. Turned out to be because most Arduinos (at the time) are 16 bit, but I was using a 32 bit one. The code had been written using `int` but also assumed that int was 16 bits!

The code was less portable because of the "portable" int sizing system. It didn't work at all with other sizes, whereas if it had been written using uint16_t it would have worked fine.

You can say "well they made a mistake", but remember we're talking about MISRA. Avoiding mistakes is the whole point.
Whisper v3
I need to clarify. I was using "the EU thinks" as shorthand for "the strong consensus view of the people running the EU". I thought (obviously wrongly) that this was obvious because an organisation cannot think.

I think it is safe to assume that the majority of people running the EU share the aim of "ever closer union" enshrined in EU treaties, which implies aiming to put the interests of the EU above national interests, which I took to be what the comment I was replying to meant by being "one big happy family"
