There wouldn't be much to add. In a one-mass system, the speed of a satellite at any point is a function solely of the radial distance r: v^2 = 2/r - 1/a. The semimajor axis a characterizes the orbit; is positive for an elliptical orbit; and is the the arithmetic mean of the closest and farthest points on that ellipse—i.e. the periapsis and apoapsis.

If you're at one of either the closest- or farthest- points, at distance r, and the opposite one is s, this reduces to

(defun speed-at (r s)
(sqrt
(- (/ 2.0 r)
(/ 2.0 (+ r s)))))

And; if you have an orbit burn at one of these points that's co-linear with your direction of motion—something that simply expands or contracts the periapsis or apopasis, as is the question here—then velocity addition is a one-dimensional scalar sum. Concretely: if you're in an orbit defined by the peri- and apo- distances (r,s), and you want an orbital maneuver, at r, that either increases or decreases the opposite distance from s to s*, the Δv you need is

(defun Δv (r s s*)
(abs (- (speed-at r s)
(speed-at r s*))))

That's all the math needed for calculating delta-v's for the maneuvuers in the OP post. I.e., the Hohmann transfer between two circular orbits, of radius r1 and r2, is

(defun Δv-hohmann (r1 r2)
(+ (Δv r1 r1 r2) ;; at r1, raise apoapsis r1 -> r2
(Δv r2 r1 r2))) ;; at r2, raise periapsis r1 -> r2

And the bielliptic transfer is a sequence of three of these. I think it's

(defun Δv-bielliptic (r1 r2 r-inter)
(+ (Δv r1 r1 r-inter)
(Δv r-inter r1 r2)
(Δv r2 r-inter r2)))

(I've left out the dimension-ful scaling factors; if you want a concrete calculation for a real object, you can scale everything throughout (inside the roots) by G*M, which is i.e. 398600 [km^3/s^2] for Earth).
The problem there is discovery. When someone local to you made a low budget film or documentary and released it on DVD, you would see that for sale in your local stores and gas stations. Now if people put that stuff on youtube it just gets lost in the noise and rarely will get the local exposure it once would have.
I'm reading Carrie, good book so far, reminds me of high school (in Maine) but more the stories recounted by teachers. It reads basically as historical fiction in the little details (jocks and seamstresses and such), while also seeming sadly in line with some recent events. In the early '70s it seems like it was cool to conform, as King explicitly asserts in the book. In the early '00s it was cool to be different. Now it seems like conformity is (was?) cool again, pretty disturbing. I'd consider making the book required reading if I were a high school English teacher.

I saw the movie in high school in the '00s, very faithful to the novel and the casting was even more amazing reading the book (which is 90% of directing, according to Scorsese (who was introduced to De Niro by De Palma)), and to me surpasses the source material. Hits harder as a linear narrative.

Supply chain for liquid and gas materials in the USA is quite robust. The western hemisphere's largest industrial complex (the Gulf Coast refining industry) can or does supply plenty of anything you can think of - including everything you mentioned at whatever purity you can imagine.

Well, Intel had a strategy and a CEO. The CEO was forced out by the board, but we don't know why. All we've heard is the board wasn't happy with the direction Intel was taking. How long have they been unhappy? How much infighting has there been on the board? What happens to Intel's CHIPS award? What happens to the foundries whose construction was already underway? Is Intel really in a complete disarray?

There are a lot of questions!
Sealed auctions are a competitive manner and the sandy hook families are in all practical reality the only creditors of note. Their damages absolutely dwarf his other creditors to the point where they were already in line to effectively receive nothing. Going against the will of the families is absurd to begin with.

> But clearly restitution is not the objective.

Sure. And damages can be punitive in nature.
Yes! It's fully real time. This was a challenge, but something we decided not to compromise on.

Imagine a pen that was only showing you words at the end of a paragraph — that'd be crazy! But this is how most people use voice today because real time is so hard. Latency is 800ms-2000ms from speech.

"Auction closed. Reserve not met. Try again."
I am not disagreeing with anything you have said here. Sealed-bid is common. Sometimes it works well, sometimes it doesn't. It is debatable if it is better or not.
Even if they weren't able to talk to anyone at this particular event, they could write much more on the subject. I'm disappointed that the article "The PayPal Mafia is taking over America’s government" is just "there was some Trump event, right-wing tech bros that raised money for Trump were there, they don't like OpenAI, legacy media and the Economist, and they threw us out" and then it ends. I feel like I was baited into reading this, expecting some deeper analysis of the relationship between Trump and his new tech friends and it's consequences. Even the hate for "legacy media" is a thing that they could write much about, and that short article could be a nice introduction for a deep dive about that. But as it stands, this article has little value.

> dollars voted are less important than outcome value to the creditors. It is their asset, no?

Sure. I’m trying to approximate a metric that gives their weighted interest. My point is the owners of the asset are selling it, and it seems their interests are obviously maximised by one bid.
The people instituting policies are not the same as the ones constructing and passing those policies. So the smartness of the policy is irrelevant. Obviously well-meaning is better than bad intentioned. Also the PayPal mafia is disturbingly bad-intentioned. And they have propaganda platforms that reach hundreds of millions of people.

There's general publicly traded shittery, and then there's WITCH (for reference, WiPro, Infosys, Tata, Cognizant, HCL).

I've seen shitty expense cutting in many publicly traded companies, but there's like this chasm between the norm and industrial grade bullshit.

Usually outside of WITCH or directly WITCH-influenced places (because let's be honest, nobody works in isolation, so the same managerial styles percolate as people move through companies), you don't see being sent people that leave you with feeling that the only qualification they had was that they should speak english according to census data. Even the one polish company that is infamous for trying to repeat similar "success" at least churns and burns mostly CS students (its late founder had a saying that you can replace any specialist with bounded count of undergrads, and that the number is usually 1).

And I don't say it to be mean about the people - they might be highly skilled in other areas, it's that the company has policy of not training them nor supporting them while they churn through them at lowest possible cost, below what I'd call the thermocline of disbelief and shame - disbelief that other company sent someone so unprepared, and shame of the managers who run operations like that.

It's one thing for your typical consulting public company to promise the stars then non deliver, hell I have heard first hand from Accenture exec about problems at intersection of sales, being able to tell customer no, and what is actually deliverable.

But there's a definite difference in degree when the "team" that you supposedly paid for is swapped the instant the ink is dry, only when contract is at risk of dissolution for bad performane slipping in someone who does not require being sent a document that has every mouse click one after another documented in screenshots.

Unfortunately that article is confused nonsense.

It suggests that making an ICE car is roughly equal to the running in terms of carbon.

In reality manufacturing is about 10%, disposal 5% and the other 85% from running it e.g. fuel and maintenance.

It then suggests that keeping an old car is better because if you keep the car for twice as long then the emissions are half per mile, but you don't scrap functional cars you sell them onto someone else. This causes a cascade with the oldest and most polluting cars being scrapped.
The first auction was illegal and this article should be seen as the mea culpa. The families bid the theoretical future earnings of jones instead of actual money. The trustee secretly accepted, but had to walk it back when it was exposed.

Canada doesn't accept refugees, they accept highly educated immigrants. That is very different. A very large fraction of immigrants to Sweden can't even read in any language, it is very hard to employ such people or educate them as you have to start with the basics for adults, but it is hard to learn such fundamental things that late in life.
>It seems to me that the Andrew Carnegies of the world had a sense of noblesse oblige which led them to try to use their wealth to make the world better. Then we had more modern businessmen who were just focused on making money. However, now with people like Musk we have billionaires who are proactively making the world worse.

1. I feel like you're giving too much credit to Andrew Carnegies, who was literally a "robber baron"[1]. He might have engaged in some philanthropy, but to suggest he wasn't "just focused on making money" is viewing the past with rose tinted glasses.

2. Define "use their wealth to make the world better". Does bill gates count? What about george soros or charles koch? Elon musk ostensibly wants humans to colonize mars. Why doesn't that count as "use their wealth to make the world better"?

I often see this with non-native English speakers, for better or worse, when looking at other comments from folks who write like that. With that in mind, issues like these bother me less.
Honestly, I'm skeptical that this even demonstrates quantum supremacy. Like I said in a different comment in this thread, all they did was let the device run for some time on whatever nonsense was in its memory and let it reach some meaningless state. Since it would take a classical computer a long time to simulate the qubits at the physical level to reach the same result, that shows that the quantum computer is much better at executing itself. But that's stupid. By that same logic, electronic computers are faster than themselves, because it would take a long to simulate a computer at the physical level on another, identical computer.

If the QC isn't doing any meaningful computation, if it's not actually executing an algorithm, then it's not possible to compare their respective efficiencies. Or rather it is possible, but the answer you get is meaningless. Let's make it fair. How long would it take a ~100 qubit quantum computer to simulate at the physical level a smartphone's SoC running for 1 second?
Someone with a bit of practice with the Munsell system can remember the difference between, say, 2.5 BG 4/8 and 5 BG 6/6 (the latter is slightly more blue, a bit lighter, and not as saturated), and can both accurately judge the color coordinates on sight and imagine what color some coordinates will represent. But both are just going to be called "teal" or "blue–green" if you have to reduce it to a single category (or maybe even just "green").

Unfortunately paint companies and others don't just tell consumers meaningful, easy to learn, and easy to compare coordinates like this, but instead make up thousands of arbitrary names so you need to describe this color to the paint store as "faded peacock" or some similar nonsense, and there's no way to tell without looking at the swatch book what the relation might be between "faded peacock", "cracked robin egg", "Aztec turquoise", and "vibrant iceberg".
Welcome to Hacker News Gil! I’m a big fan of your work in complexity theory and have thought long and hard on the entropy-influence conjecture revisiting it again recently after Hao Huang’s marvelous proof of the sensitivity conjecture.

To answer your question on why the hyped fantastic claim, as you must know, the people who provide the funds for quantum computing research almost certainly do not understand the research they are funding, and need as feedback a steady stream of fantastic “breakthroughs” to justify writing the checks.

This has made QC research ripe for applied physicists who are skilled in the art of bullshitting about Hilbert Spaces. While I don’t doubt the integrity of a plurality of the scientists involved, I can say with certainty that approximately all of the people working on Quantum Computing Research would not take me up on my bet of $2048 that RSA2048 will not be factored by 2048 —- and would happily accept $204,800,000 to make arrays of quantum-related artifacts. Investors require breakthroughs or the physicists will lose their budget for liquid gases — certainly exceeding $2048.

While there might be interesting science discovered along the way, I think of QC a little like alchemy: the promise of unlimited gold attracted both bullshitters and serious physicists (Newton included) for centuries, but the physical laws eventually emerged that it is not scalable to turn lead into gold. Similarly it would be useful to determine the scaling laws for Quantum Computers. How big of an RSA key is needed before even a QC exceeds the total number of particles in the universe to factor it in reasonable time? Is 2048 good enough that we can shelf all the peripheral number-theory research in post-quantum-cryptography? Let’s not forget the mathematicians too!

Yeah, I'm not referring to drawing which is copying.

> There's very little that can be taught about drawing.

While drawing from the imagination is largely about using the intuition. The intuition can be trained just like the more analytical side of the brain. I can teach you a few properties of rotation/space, etc, and then give you the right exercises, and then you won't need to use construction to draw.

KJG does have some innate ability, and he was clearly obsessed, but it's not actually the bulk of his method. He has a video about drawing scissors. He can articulate nearly everything he is drawing, specifically the function which guides the design. There are others who can draw like him. Look up Tom Fox.
Even the other companies basically just do his bidding. Remember when he 'shared' engineers around between different companies?

My comment has nothing to do with moral righteousness, merely legal correctness.

However, the idea that the InfoWars brand is worth less than $10 million is a bit silly to me given its reach among crazy (and highly manipulable) people, and the low size of both bids (and the fact that only people intimately involved in bankruptcy procedures knew when and how to put in bids) suggests that the auction process was probably not run correctly.
It's also true that this forum and the startup ecosystem in general doesn't represent the reality of global software development. Saying "PHP is dead" is accurate if your entire world is silicon valley.
I haven’t been following closely - I wonder if the people who made the death threats were charged? I haven’t heard anything about that.
> It is debatable if it is better or not

No, it really isn’t. Not with two bidders. The moment the first party announces their bid you have perfect collusion (if the second party, rationally, runs out the clock) or a stalled auction (if running out the clock is impossible, thereby always allowing someone to always claim they’ll bid better).

For me, it’s using backslash as a namespace operator. You know how in Rust you’d write somepackage::foo? In PHP that’s somepackage\foo. I can’t stand looking at it. It sets my teeth on edge.

(I’m sure they had valid reasons for picking \. I don’t think they’re dumb. But seriously, I’d rather use an emoji or something instead. At least then code wouldn’t look like it’s full of escape sequences.)

> They earn a non-negligible cut, yes, but stating that they're "taking 1-3 pennies" is simply not true (or rather, you'd have to expand your statement to "the card payments industry in collaboration with consumers").

That's the range of fees that the merchants have to pay [1], subtract about 1% for "cashback" programs, and that leaves 1-2% to Mastercard, the payment processor service and the banks of the consumer and the store. It's a hefty amount of money, no matter what - and MC has a very healthy profit margin [2].

> Girocard does not have a viable story for online payments (no actual processing capabilities beyond some Apple Pay only pilots, importantly no dispute resolution mechanism, which is critical for online payments, etc).

I'm talking about physical presence payments primarily. But for online, SEPA Instant Transfer works out just fine - 10 seconds processing time from payment initiation to confirmation for the merchant, and dispute/chargeback has been a thing in SEPA Direct Debit and SEPA transfers from the start. Only thing is quite a few banks don't support it because their core IT is decades old.
