Think of it as the amount of energy you can store in a superconductor.

This is talked about in terms of the ‘phase diagram for superconductors’

http://www.supraconductivite.fr/en/index.php?p=supra-levitat...

As you put more current in the supercondutor, eventually you break it and it leaves the mode, as it gets hotter, likewise, as the magnetic field gets stronger, likewise.

You want the largest ‘area under the curve(s)’ to handle more and more ‘superconductivity’

New materials are enabling this which has the cubic effect mentioned for reducing confinement volume and making things more affordable and increasing energy densities that can be contained, etc.
The actual fusion in the sun happens in only a small part At the middle. The rest is just there to provide mass :)

> Also, something else I never grokked, how do you get the power out? The plasma heats up, but how do you turn that into useful electrical energy?

Steam turbines; same as fission or coal. Or gas turbines, if you want to get fancy.
That’s not actually true. Compute cycles would be the best proxy for deployed hardware. Just delivering bits doesn’t actually take much hardware. (And not even sure why the amount of deployed hardware is a great metric.)

We specifically aren’t interested in pure bit delivery. It’s a commodity business that will have its margins squeezed to zero over time. We provide CDN services because caching is a useful tool in computer science when you want to deliver performance for other applications. If you measured our revenue per bit delivered, it would be far more attractive than any of the traditional CDN providers because we aren’t primarily selling bit delivery where they primarily are.

The f18 Fortran compiler has a novel algorithm (calculating in base 10^16) for conversions that is fast and doesn't require big look-up tables.

i think most people would just use TF/PyTorch and ignore the specific technology on the backend. not much GPU specific stuff to learn -- very, very few deep learning people write their own CUDA code.

so the question is just -- when will it be very simple to install these packages for AMD GPUs, with enough mathematical operations implemented and optimized to let you do the things you want to do.

right now things sort of work, but it's definitely in a bleeding edge early adopter state. it's seemed like AMD is on the cusp of catching up for a couple years now, but it's taken longer than I expected.
You're right, I had Western Europe in mind, as well as the USA where more people have experienced war through Call of Duty than in real life.
Does this mean something more than "all software is either generic (scale) or specific (consulting)?"
It’s important to keep in mind that MIT is working hard to monetize HTS coil production. There are some unseen hush hush politics at play here.
Yes similar to planes its an energy density and cost issue for the batteries although weight is less of a concern. I would imagine you could do some interesting things too like have the train run through an electrified section to charge itself and then run through a non-electrified section on batteries.
When I started working on standardizing ActivityPub in the W3C Social Working Group, the main thing I heard from everyone (including here on Hacker News was): "You're wasting your time. There's no way you're going to get all these projects to talk to each other, everyone building distributed social software is too stubborn to do that."

Now ActivityPub is the most widely adopted federated social network standard on the web ever, with dozens of projects using it, thousands of servers, and millions of users.

I did sometimes feel like giving up when I heard that kind of feedback then, but I'm glad I didn't. I'm not going to give up here either.

The project is ambitious. It's broken into many subprojects so that even if the larger goal doesn't succeed, we might still get a number of useful pieces out of it.

But I've learned not to let comments like this dissuade me. If I had, ActivityPub wouldn't have happened. We might fail, but more likely, we'll have a partial success, which is still useful. And it's worth trying.
What if I don’t think Mr. Marketer has a god given right to help me receive more relevant emails, and I would like a way to indicate that preference to my mail client which downloads emails on my behalf from a mail server I pay good money for? How does the current email tracking infrastructure facilitate this preference? What actual choice do users have in this matter today?

Until we actually figure out these questions outside of layering hacks (i.e. “block image subresources entirely”), it seems like we should definitely put a pause on the whole effort.
Whataboutism. A company behaving poorly doesn't excuse another company from behaving poorly.

Horrible - to use your word - is horrible, no matter how many people are doing it.
>On average a college graduate will have one million dollars more of lifetime earnings than a high school graduate.

Does that statistic account for greater starting wealth of college entrants?

Society is still largely bound by the human intellect. So, I don’t think overall complexity is actually increasing significantly. It’s more a question of how obvious the complexity is.
You can have Atkinson cycle with diesel, so 1) do they, and 2) how much does that offset the transmission losses?
I worked on a very popular free desktop product (BitTorrent/uTorrent) when a major revenue stream was the bundling of crapware in the install path, depending on people clicking the dialogs without reading them. I remember an executive announcing in a meeting that "search engine replacement" (reconfiguring your browser and/or system to a shadier alternative that made us money) was viable because the telemetry data showed that not very many people uninstalled in the 2-3 weeks after this was done to them, so, yay! another revenue stream people don't seem to totally hate! But they had read the tea leaves wrong and the backlash eventually caught up with them. It shows that reading mountains of data (100 million+ active monthly users) and reaching solid conclusions about user sentiment is a black art and numbers can be presented to show whatever point of view you want.
The guesses it makes when it doesn't know a recipe are hilarious. I've never used head cheese in a chocolate mousse, but hey, who knows.
> "they typically use Atkinson cycle engines"

Only the early-model Toyota Prius used Atkinson cycle engines, up until 2003 or so. You'd be hard pressed to find a modern hybrid using Atkinson cycle. Any modern Prius uses conventional engines with variable valve timing.
How is the cost per MWh in construction and ops?
I'll second this. Great resource.
I use this on my invoicing app. I implemented it after years of the app's users telling me that some of their customers/clients would consistently deny getting their invoices. This required me to sift through my email server logs to see if it was successfully delivered and that's a pita that was costing me time and my app's users a lot of frustration.

The app also allows users to create estimates, proposals, receipts, etc. I don't implement tracking on any of those documents, only invoices. An invoice is a "legal instrument" and I consider the documenting of it being opened a tool my users can offer a court of law as evidence their invoice was successfully delivered and viewed by the recipient. A court can certainly reject it, but they may also accept it.

I see it as little different than paying the Post Office for "Tracking" something you've mailed with their services.
its an early stage co it seems. more info here if you care https://www.startupsfortherestofus.com/episodes/episode-516-...
This is a great template! I have a personal theory about extending what you wrote above:

Async verbal meetings > Async Google Docs > async Slack > meetings

...and I'm writing an MVP for a tool to do it[1]! I hope that a lot of people will run async verbal meetings and do team-wide chats via asynchronous audio in the near future, because it's much more convenient and comfortable than long, synchronous video chats or laboriously editing text messages for technical content and tone.

In most ways, my MVP is just like IRC or slack, but it lets you also send audio, and it auto-transcribes the audio as a chat message, with a play button beside it.

I think meetings are one of the biggest use cases for a tool like this, so building some default structures like the above and publishing them out as artifacts is certainly in the milieu of ideas I'm trying out.

yes thats true. ITER is obsolete already because it actually cannot use these high-temp-high-Tesla superconductors. at the moment ITERs best hope is that it 'proves' that fusion is viable & then do a full redesign for DEMO to do proper scaled operation.

Show HN: Hammer – Golang's Fluent Rest API Client
Well I grew up in the Northeast ('80s). One thing I can assert that these missionaries treated the population a lot more respect than the (for the lack of a better word) folks from mainland India. The common attitude towards Northeast people by my fellow countrymen was that of utter contempt to the point of treating them as inferior beings.

Sure the missionaries had an agenda. But given my options as an hypothetical person of northeastern ethnicity, given the education that I would get from the missionary organizations (they run many primary schools and high schools and vocational training schools) I would have made a wise choice and bettered my life.
You aren't free unless you can say and do things without consequence? What?
I very much know my comment history is public.

Except for two comments, I'm replying to other people comments or adding more resources to my previous comments.

I'm a developer, I'm don't belong to BJP IT-cell, like the other guy is mentioning.

I have just seen that, my country is being depicted badly for wrong reasons, despite evidence against Amnesty.

As a citizen of this country, I felt responsible to educate and put forward, whatever I know.

I have started commenting from around 4:30PM IST, while traveling.

I didn't provide any sources for claims I have made previously, so I was indeed visiting each and every comment of my own and adding references, and replying to others.

Edit:

If you want proof, except for two comments, which I have copy pasted.

All other were responses to other comments.

I can share a screenshot, on telegram or gmail, my username is same across all platforms.
Right; the person saying "I literally wrote the book - hire me" is saying it matters most, and I think that approach is likely to backfire.

There are multiple problems with that attitude, including: 1) You probably aren't hired to write books, so what matters most is other things you'll be doing. 2) There are really good books and really bad books, so saying you wrote _a_ book doesn't carry the weight you may think. Was it good?

I can see how censoring yourself to the point of silence is bad, however, as someone who spent a great deal of time expressing my sometimes offensive POV's with very little consideration for others, the forced filter and permanence of the internet has benefited me. I am more careful and thoughtful about how I express myself now.

After a couple months of nothing but ads for bodice-ripper romance novels with semi-clothed, entwined bodies on the cover

There was a time that the Kindle ads were actually appropriate. I've even purchased the odd sci-fi book that showed up on the wake screen. But that's been a couple of years. Now I get the same bodice-rippers you're seeing. What a waste; Amazon has my book purchase history going back 20 years, and that is what you're showing me? Do your advertising customers know this? Because, shallow guy that I am, I read sci-fi, philosophy, and books on distance running. That's pretty much it. I did read part of a Danielle Steele book (imagine GPT-3 wrote a romance novel...) 35 years ago when I was married to a woman who read those, but I doubt Amazon knows that.
Because the laws and treaties that enable it were enacted by the US government.
Fair enough - I personally recall seeing a lot of titles at the $49.99 price point, but the Nintendo store itself is infinitely more accurate.

It doesn't change the underlying point, however.
Please could you explain this bit a little further?

> The shifting attitude towards offense isn't so much the result of technology as the article suggests, or changing culture in the upper strata of society, it's democratisation of discourse to people for whom discourse actually matters in the real world. I think this is why the change has been so pronounced in the US in particular. In the US, average people for the longest amount of time had no ability to speak at all

Why did people in the US have no ability to speak? Or have less ability than those in some other country?

Or are you saying that social media took off because those in the US already felt free to speak and then a platform appeared?
The amount of false negatives (users received the invoice but disabled tracking pixels) must be large enough soon to cause issues for you on its own.

Paying the post office is very much different, for obvious reasons.
Often, you're too late and the cake is baked when innovation is reactive.
> is that that means the state has power over you

This is a recurring theme that I despise. People need to start to talk about the government in a democracy as "we". You are the government, the state is a collective you are part off and have power over. You are in fact dependent on others, that is the point of a society.

So when someone says, hey, when I joined this society, I was told its people upheld the right for all its members to equal opportunity? But my parents did not have the money that yours did? And that affected my opportunity? So what gives?

When you have the attitude of the government as a seperate entity, it becomes reality. The more you see the government as such, the more it is allowed to become a ruler over others, since that's how you depict it. When it should be the CEO that you, a member of the board, elected, and can booth out when you don't like what they're doing no more, and you also can join the government if you want to contribute more, etc.

Sorry to hijike your discussion about handling the homelessness crisis , but that's a sore point for me. I find it really weak of people to look for someone else to govern them, and I wish people took responsability for their government (in democracies), because they are its owner and fundamentally have power over it. But too many prefer to delegate and pretend they're powerless against the faceless man.
That twitter handle is far from an unbiased source.

Again, my question here is -
Who decides that the reason someone has chosen for their conversion is “wrong”, for what is essentially an individual’s choice. I for one trust nobody but myself to make those judgements, within the framework of the law. I do not want the state to infringe on my personal freedom. Anti-conversion laws are a dangerous step in the direction of the state telling people what to believe and what not to.
Are there any open networks in range? How do you know it's not jumping on those?
I was born in the late 1980s and thus was too young to experience NeXT in its heyday, but sometime in high school was when I learned Mac OS X and its NeXT heritage. I was enamored by a highly usable Unix GUI, and since then I've been a fan of Mac OS X and NeXTSTEP. I even own a non-working NeXTstation Turbo Color that I bought on eBay with the intention of restoring it.

However, I was so intrigued with NeXTSTEP as Unix with a polished GUI that I didn't realize or appreciate its Smalltalk influences until roughly a year or so ago. In a way, NeXTSTEP could be thought of as the realization of a polished Smalltalk desktop, albeit with Objective-C and Unix rather than actual Smalltalk. On one hand, NeXT lacks Smalltalk's image-based, live-object environment, which I think is something that would still be revolutionary if a desktop operating system environment offered this today. (My dream is a desktop based on live objects, but the substrate I'd personally pick would be the Common Lisp Object System with its support for multiple dispatch.) On the other hand, Objective-C brought the benefits of Smalltalk-style message-passing object-oriented programming to NeXTSTEP programmers while being compatible with C, which was important for supporting an ever-growing base of software written in C. NeXTSTEP also sweetened GUI programming through its Interface Builder, which was originally for Lisp.

On a somewhat related note, there were attempts by Apple to catch up to NeXT or to even leapfrog them. The Pink/Taligent project would have created a modern operating system (e.g., one with preemptive multitasking and memory protection) with an object-oriented API, though that API was in C++ instead of something more dynamic such as Smalltalk, CLOS, or Dylan (Apple's own internal language that was heavily Lisp-influenced but had an Algol-like syntax). Unfortunately this project failed, which led to a scaled-down effort called Copland (the original plans for Mac OS 8) which also failed, which ultimately led to the purchase of NeXT and the return of Steve Jobs.
it is criminal. if you did it, you would be thrown in a cell for 30 years for wire fraud. remember that in america, the rules are different for corporations as there is plausible deniability for the board... as such, only fines are ever enforced which are taken into consideration when making such moves. jpmorgon might have to pay a 1B fine, but they might have made more than 5B in the transaction.
One of the reasons I avoided as hard as I could getting a "SmartTV" and went for a standard LED display. Those are getting harder and harder to come by though.
Either that, or the custom search was impossible to remove for non-technical crowd - AKA "the conduit business model"
Take the printed money and:

keep it in the bank to shore up fractional reserved deposits

buy bonds that no one wants because you are paying to lend

pay interest on debt, often within the same entity

pay fees to hold deposits or buy bonds

All that takes dollars out of the world. The few dollars that get through stay at the top, paying the people who messed up in the first place. They keep on making things no one wants, so you have a glut of that. Few dollars chasing an abundance means price really should be zero or "just take it" or even "I'll pay you to salvage junk."

Add in the people who mess up take that free money and do things like stock buybacks. The price of their stuff skyrockets. Or lowering cost which means not hiring anyone. The barrier to access increases. You have to be a computer programmer to land a secretary job, or unify physics to be in sales.

Why is this done?

Generational: A lot of teenagers. A lot of seniors. Few people in their prime earning years. If you let the Fortune 500 collapse, you get all that above. Also the people who have access go back on the soup line with you. They share knowledge. They collaborate. Doing it now will kill the young and old.

Diplomacy: Money will go somewhere else. Mercantile dictatorships. Piracy. Not too big of an ask if what we really are buying is not another world war.
You're thinking about scale in a different sense.

> You can do things that don't scale to accelerate a good idea, but by definition you actually can't do that if the idea itself requires scale. The idea has to work on day 1, for customer 1.

He's talking about ideas that only work if the company has scaled to some non-trivial size of users or some other relevant factor. Uber would be an example. How could Uber work if there was only 1 customer? There would be no drivers.

If you need to "do things that don't scale" to launch your idea, your idea probably also needs to work with low scale of users/revenue/investment or you will be dead in the water.
How much work is actually done here? Looks like it uses gg-editor to do everything from a glance
Without harsh government rules to prevent this kind of insidious behavior, this sort of thing is... inevitable.

so you get the plasma spinning and you have two problems: containment and instability. better magnets and faster control systems are the two big things that (in my layman's-bad-at-physics understanding) have really advanced in the last decade.
Unfortunately, the BJP's notorious troll army (also known as the "IT cell") has invaded HN also, and pop up whenever our government's misdeeds are discussed.

Remember that this is the same govt that has restricted the speech of the state of Jammu and Kashmir by cutting off their Internet access completely and later, restricting them to a mere 2G connection and to "approved" websites. [1]

It modified the UAPA law to basically designate any Indian citizen a "terrorist" and hold them indefinitely without bail. And used the law to arrest and detain people protesting against a controversial law. [2]

The same government that set up a "donation fund" called "PM Cares", ostensibly to help people affected by Covid-19 and lockdown, but then refused to divulge details under our RTI - Right to Information Act - claiming it was not a public authority. [3]

But then exempted this fund from the same draconian FCRA rules [4]

Oh, if that's not enough, this government also passed a law exempting political parties from scrutiny in foreign funding under the FCRA. Want to guess which is the richest political party in India now? Google it. [5]

Did I mention they also introduced "electoral bonds" to allow anonymous corporate funding for political parties? [6]

Amnesty International was drawing too much attention to the human rights abuses of the government, so the state has come down with all its might on it.

I don't think that line of thinking will get you very far. You can pick up the ball and run with it in American football but not soccer. You can insider trade in US commodity markets but not US equity markets. Spoofing is illegal in US equity markets because that was the result of the rule-making process. I'd argue that banning spoofing is a good rule for equity markets, but it's not necessarily a good rule in other contexts.
Yeah all very bad. Dunking in cow urine and bullshit for protection from Covid that's golden and kosher though.
