Good answer, thank you. Like I said, it all boils down to the cost of H2 production for a given process. If you have a path to get to $1/kg H2, that is truly awesome!

Working very peripherally in this sector, I applaud your efforts, not only for the ingenuity, but also for the guts to consider environmental impact as opposed to stock-holder happiness from a profit margins perspective.

Honestly, it would be cool if on your site you showed a side-by-side comparison on your profit model compared to a competing natural gas reforming competitor's profit structure to demonstrate to customers how you are sacrificing some profit for environmental benefit, whereas the competition simply pockets the profit and turns a blind eye to the environment. For me, that would help me decide to buy potentially higher cost H2 from you, just like I choose to pay a higher premium for energy I know is renewable sourced.

The world needs more innovators like you folks. Good luck!
I wasn't able to find any working examples from the homepage, even with the updated link. Can you link directly to a demo page or two that uses the library, rather than a Github repo with code that uses the library?
Yeah but it gives people a warm and fuzzy. Just like companies hiring “senior software engineers with at least three years of experience”.
But it has not the newest security fixes for putty :(

In addition to this. About Python and typing, have you tried mypy (statically typed Python)? I find the typing story quite decent since Python 3.6. I use it on every project that goes above ~1000 LOC.

I love RTX, but it's so hard to demonstrate it. It doesn't give presence of any "wow!" effect (apart from demos that overdo reflections), it only gives absence of incorrect shadows, and humans are bad at noticing absence of things.

Instead of "wow" you get "well, duh, that's how things should look".

If you are leaning more towards contracting than consultancy then I did write up some practical starter tips [1]. Note it is biased towards my situation at the time, IT related contractor based in London, but I think it holds up as general advice elsewhere as well.

I think smith's early take on "division of labour" unfortunately conflated two different things, either of which could be called division of labour.

One is what he described in the pin factory, some basic precurser to a factory/assembly line. One person draws wire, another cuts it, another sharpens..

This is not about specialized skills, or even labour. It's industrial engineering. Break a process down to components and optimize individually. In simple cases like this, just breaking down the proccess is 90% of the way. Give 3 people the job of sharpenning an endless pile of pins and the improved tools/methods will follow.

This bleeds into industrial labour (Smith's example for this is pin packaging) in a few ways. Once you have small, efficient, tooled compnent processes... you don't need skilled labour. Pinmaking might be a specialized craft, but anyone can be taught to sharpen.

This is the opposite of the other kind of division of labour.

When historians (especially british ones from the same period) theorized about early civilisation, specialized division of labour featured often. Early cities had enough people that not everyone had to farm. You could have specialist priests, soldiers, artisans, stonworkers, smiths, boatbuilders..

This is where specialized skills and depth of knowledge comes in.

So... data science & pins... The first kind of division of labour is the "organization as a machine" kind. People do a consistent reptitive process. This works very well, but only if you need a cvonsisten, repetitive result.

I think what this article is mostly argueing is that data science (like programming, engineering and a lot of "information economy" jobs) is but shouldn't be organized this way. You don't need a consistent, repetitive result. If you do, that's what computer programs are for.

I agree, I think. Like with a lot of software domains, there's a stark differenc ebetween small projects where requirements, design, architecture & implementation can be done in one head and big projects that can get bogged down in bureucracy, misunderstandings and the inability to move back-and-forward between elements. I think data science has the extra problem of datasecurity and other things that require controls and rigidity.

I expect a lot of these problems will lessen with time. The field is still in growth phase, and both tools and skill levels will improve.

Circa 2005, a problem I cam across all the time was impractical designs for web apps. You'd have a designer who had been designing posters and liveries. They'd make a picture. Then you had a html guy, who would try very hard to make it happen in html. Then it'd go to a JS or server-side specialist, who discovers that and arbitrary amount of text needs to fit neatly into a box that fits exactly 416 charachters of lorem ipsum.

Nice work. Thanks, for making it available. I'm teaching compilers in the upcoming academic year. I'm
thinking of using this tool. I have two questions.

1. How mature/stable is it? I know that's a bit difficult a question to answer for the creator. But I'll have > 200 students, and if the tools I give
them are buggy I'll have to deal with a complaint avalanche. (MARS
is very stable.)

2. I want to build a test suite for automatic evaluation of student
code generators, such that student RISC-V code is automatically run in the simulator
and the result of the evaluation is compared with the expected result (I supply the latter). The whole thing needs to be scriped, since my test cases are numerous, and I don't want to cut/paste student code into a window. Is there any
facility that allows me to use your simulator as a linkable library,
rather than calling it from the command line? This would be
extremely convenient. (MARS can be run from the command line and can be scripted into a test suite but it's a bit inconvenient.)
> At the very least, rehabilitation doesn't work very well.

WHAT!

> Rehabilitation sounds societally useful, but the failures have been overwhelming. Justice? Deterrence?

WHAT! Mind sharing some sources?

IMHO you have it completely backwards.

I can point to plenty of European countries (Norway, Germany, Netherlands, etc.) that focus on rehabilitation, not punishment.

Their recidivism and overall crime-rates rates are significantly lower than in the US and their prisons don't look like 3rd world shitholes.

They blow the US out of the water on every metric. If anything has failed (and spectacularly so), it's the idea that focusing your prison system on punishment works.

I can't fathom what gave you a different idea.
Such defeatism is why we have to put up with clunky 50 year old abstractions and the over-complicated "ecosystem" of webshit we built on top of them.
Indeed, it has a strong connotation, I guess I should have used unfair discrimination or bigoted discrimination or something... Although to avoid confusion, I prefer to use a different word for "legitimate differences", such as distinguish or differentiate.
> The difference from RT Quake to Quake it’s only that the lights are not precompiled

In the linked demo video they also use new high resolution textures. Which include not only color data as in the original Quake, but also normal maps and maps with PBR parameters (metalness, roughness).
I think this is more romantic “grass is greener” thinking. It’s pretty hard to compare effectiveness of prisons for rehabilitations across countries. There is some research [0], and there is a lot of limitations in data, but it seems like Europe isn’t doing so well on recidivism. Or at least France and Germany seem to also struggle with people leaving and then reentering prison.

If I had to guess, I would say that prisons, in general, don’t rehabilitate. They just isolate for society’s protection because no one has a good idea of how to fix people that has effectiveness efficacy.

The reality of tipping culture is that these workers are vastly overpaid for their skill and effort level.

That's why they're fine with their salary being less than federal minimum.
How much did their education cost? At least in the US, doctors don't make that much after student loan payments, insurance, etc.
Most open-source software being the exception
Take a break, honestly. A lot of people seem to be of the opinion that if you don't work your life will start to implode around you.

I've just started my first consulting job via a friend I used to work with. I was 10 months unemployed, living in an exotic country, enjoying myself and building out my own projects. I only ended up taking the job because the pay was good.

Whilst I've been doing my own thing I've met a lot of 'digital nomads.' They all do interesting things and the stories of how they got there are all different. And if they don't like it anymore, they can stop at any time.

In short, there's other options than diving from a job that's burnt you out straight into a consulting gig.
But there isn’t a limited supply of insulin or a sudden spike in demand that would drive a normal market price rise.

If anything the larger market, which is stable over time, with a product that is known and doesn’t require a lot of development & research, should be driving the price down as competitors should be pricing to gain more market share. But that’s not what’s happening, the companies are engaged in anticompetitive pricing.
I was meaning in principle.

very much this.

It's like playing in a lottery that you win almost every month, and if at some point you lose, you get a lot of money.
In Russia this costs 180 RUB ~= 3$, and it is not subsidized, but is sold over the counter, so already includes markup of distributors and pharmacy.

I bet manufacturer (pharma company) receives only $2 or less of these money.
Window 7 Ultimate Crack Plus Product Key for 32/64-Bit 100% Working
The whole society pays for everything that is shared. Like roads. Or White House. Expensive cars and plane tickets subsidize cheap ones.

The reason costs go up is because in some countries someone sees health insurance more as an opportunity to line their pockets since there is less transparency on how the money is spent and the pool is so big it offers temptation. But this is a problem of implementation, not the system’s concept. This is corruption where “negotiations” with healthcare providers and pharma are more about commissions and bribes so the actual costs don’t matter.

Same as with the road building I mentioned above. Is rod building soacialist?
Because there has never been any positive effect from deriding others?

From social change (e.g. "look at these backwards bigots"), to running a tight crew ("wtf Kowalski, you stupid! You nearly got us all killed"), deriding others can just as well have positive effects.

Then there's the fact that some things naturally and inevitable deserve derision.

Not all ideas are derision proof.

Let's have Theranos or Fyre festival or non-vaccination as an example that we all agree on.

A healthy society should include a healthy dose of derision for derision worthy ideas.

(And if you think my argument above is stupid and deserves derision, then you've just made my point!)
Yes. There is this question of 'what is art'? and we can assume that old cave paintings are 'art' but is it really? Is that just us assuming this is 'art'?

Art as we know it really is a capitalist contrivance. Sure the communists had art too but do native people outside of regular capitalism have 'art'?

In Canada they tried to get an art exhibition together of native people's art. It didn't really happen. They tried teaching them how to make art but they didn't get it. This was not because the native folk were primitive and backward, far from it. They had plenty of beautiful things they made as part of their daily existence. However, they did not see the world mediated through images and capitalism. They weren't worshipping icons either.

Before capitalism as we know it took over the church had all the power and art was invariably made on some Bible oriented theme. Nobody painted scenes of rural peasant life, it was always the baby Jesus.

I am sure that everyone puts some art into what they do. Writing code is an art. The medium just isn't brown pots or watercolours. Code is a creative medium though.

Music is an interesting one as we all grew up at a time when we partied for fun. The guy sorting out the music was just contributing to it. Then we grow up and meet musician friends. And yes, all of them are out to make money, it isn't just about the music any more. It probably had more to do with sex first time around so even then it wasn't entirely just about the music.

This is why music is not at all useful for revolutionary or activist causes. There aren't many John Lennon's in the world willing to stay in bed for peace.

Sometimes I hear of musicians I listened to many aeons ago and wonder when it is they will get a proper job. Years ago it was about the music, now it is about paying for the kids to go to private schools.

Most of what we know of as art because it commands price tags is 'art business'. This is just a game and the likes of Damien Hirst know how it is played.
Is this ray tracing or path tracing? I'd think that real-time path tracing would still be hard/impossible in real-time considering the number of samples, but I'm not sure. People throw around these terms interchangeably which complicates the discussion, though the algorithms have notable departures from each other.
I'd do it right before releasing the product if you don't need to do it earlier.

You should track money in/out now, don't wait until the company it setup. You can claim expenses on the company even if those expenses were incurred before the company was formed.
You could apply this argument to almost literally anything that people do or have done for money.

Yes, there is a reason nobody is making money selling NPM modules and that is the marginal cost is zero and there is no constraint on supply, people like to do it for free.

Doctors and Lawyers have professional guilds that legislate to constrain supply. Hence the price is high.

Competence doesn't really come into it, even in the high art world it's more about who you know than what you know. No amount of wishful thinking will change this.

... which will balloon to 600, 800 Euro/month, as you get older. And if don't maintain the same level of income as you retire, you might have another thing coming - the public insurance will not welcome you back.
A situation that happens in Europe too (though not to the point of bankruptcy). Then there are private insurers, sometimes mandatory. And there are situations where even public + private healthcare do not cover all expenses.

Can algorithms be patented in Europe?
Unofficially, it's very comparable to the MIPS architecture, but (much like e.g. the Alpha) it avoids some of the issues in MIPS that make it less usable for "high-performance" implementations. The extensibility is a fairly novel feature, as is the approach it uses for compressed, 16-bit instructions (a "clean" alternate-encoding for a subset of the same 32-bit instructions, not a new instruction set). Furthermore the instruction format uses some tricks that simplify decoding in hardware, although they do make a pure software implementation a bit harder.

The upcoming V (vector processing) extension also chooses an approach that (while far from novel) hasn't seen much use recently, but will probably work better than the usual sort of SIMD for most use cases.

It's worth mentioning the "privileged" architecture as well, as it benefits hugely from being a from-scratch design; it's a lot simpler than its equivalent in most other architectures, and it will probably support things like virtualization in a rather straightforward way.
I really don't use Windows all that often but when I do I now really prefer to use WSL and a proper OpenSSH or mosh. Even running in the default Terminal it's still nicer than PuTTY, if I have the choice though (and when the next version fixes input of AltGr (does not apply to US keyboards)) I prefer to use the Windows version of alacritty.
Isn’t it a security feature linked to a max load or a category of cargo? It could be a good reason: “Mixing cargo and luggage is only allowed on planes with a secondary extinguisher” => We sell the secondary, not because security is optional, but because we sell the ability to do something more with the plane.
To clarify, a limit after which you no longer have to pay. Not that that's all you can get :)
Apologies, I keep trying to quash this one but it keeps reappearing. The reason MCAS is needed is because the engine nacelle generates lift at high angles of attack. This meant that there was a lack of positive control required to increase angle of attack.

I understand this as if you need to pull with 10KG of force to get a 10 degree angle of attack, then you need to pull with at least 20kg to get to a 20 degree angle of attack. I'm not going to claim that's 100% accurate but I believe it's close enough.

This is a generic requirement of part 25. So had the 737 Max been a clean sheet design it would have been a requirement. It's not just a compatibility layer to make it behave the same as old aircraft. It's a fix to make it meet the requirements of certification.

Training only came into it at the point that Boeing declined to add it to the difference training, charitably, because they felt the system was covered by existing procedures or, less charitably, because they wanted to downplay any differences to make the aircraft more appealing.
Then it's an inefficient method to do so, because along with discouraging these particular people, it may also discourage many other productive and competent developers who don't wish to condone this sort of abusive leadership.

Pick you poison. :)

Violence is a consequence of many factors, and in a decent democracy having it monopolized with the governement we have elected is probably a good thing.

The great thing is that we have history as a reference and I think we should use it.

I’m not aiming for the extremes here, but rather life and living standard in the world and perhaps west specifically, post WW2.

The numbers are there, we can see the trajectories.

The numbers seem to say, pretty clearly — having a great standard of life seems to gain everyone (except for perhaps the ultra wealthy).

Think about this, and give me you view:

Why is the worlds most happy nations also the ones taxed the highest, and as such have the biggest government influences?
Path tracing has huge wow factor. The problem with RTX is that on current gen hardware it runs at laughably low sample rates and the result is very noisy even after DLDN.

Games are handling this by dialling the amplitude of RTX effects way down and having a smoothing pass. After all that is done, the wow effect is gone and you're just left with a more dynamic version of the same or worse aesthetics that we're already used to.

I expect it'll truly take off on next gen hardware, whenever that rolls out.

Here's what RTX+DLDN actually looks like if not dialled down and smoothed: https://youtu.be/CuoER1DwYLY?t=553

My takeaway is yes that quake 2 demo looks really cool, but you just know that they used every black magic hack in the book to get there, and most of it can't be replicated in a modern high fidelity game. It's definitely not a case of flicking an 'RTX on' switch.
The point is that library doesn't have to be Flutter or written in Dart at all.
Fair point. Most of us here on HN don't require smartphones for that, but I take your point. Everything you list as a key benefit for poor people doesn't require an expensive smartphone, or at least, wouldn't if adverts weren't sucking up the compute and battery power when using a web browser ;) More seriously, though, beyond those basic capabilities, which we (ie not poor people) have had as long as I've been using the internet and while crappy adverts have always existed (punch the monkey and win a prize!) online, the amount of low quality content we consume has increased substantially, largely due to social media imho, which is supported by ads and is what I'm arguing against. I don't disagree with what you said here at all.
You're right. Advertising is just a symptom of the root problem, capitalism.

"Attention is currency in the marketplace of ideas" as they say. If everyone is supposed to vote with their dollar, you need to make them vote for you. The easiest way to do that is by fighting for your attention.
And once you get older, your private insurance premiums rise, which you may not be able to afford. Public insurers won't let you back in.
