Not the person you were replying to, but broadly, Market makers delta hedge in the future. What this means is you take your option, you figure out how much the price depends on the future, and that's your delta.

An at the money option will have a delta close to 1 - ie, if the future moves $1, the option price will basically move $1 too. So I can hedge my exposure to the option I just bought or sold by just buying or selling the same amount of the future in the opposite direction.

A far out of the money option will have a delta close to 0, it's price isn't going to move much when the future moves since it's still incredibly unlikely to come into the money and actually be worth exercising. So in order to hedge an option, the market maker only has to buy a tiny tiny amont of future to hedge the delta (or may not even hedge because they're willing to take some exposure to delta for some period of time, or their net delta position due to other options they've bought or sold cancels it out).

So the plan of "I'll buy these super out of the money options to force market makers to hedge" doesn't make a lot of sense - since for each option you buy the market maker only has to buy a tiny tiny amount of futures, and you could be buying 100 call options and find that all your purchases have been cancelled out by the market maker buying a single call at the money - not even touching the future. Now if the out of the money call options are cheap enough it could be more effective against the price that just buying the future, but that's incredibly unlikely, market makers aren't stupid and for these extremely out of the money options they're probably already charging a premium since they're difficult to accurately price.

Meanwhile, is the price of the underlying the only thing that causes the price to change? No. Gamma (or the value of the time between when you bought and the time to expiry) is a compenent, that's going to collapse coming into the last days of the option so you're paying for that. Volatility also effects the price, and you're probably paying a premium for protection against volatility that you're actually hoping against.

Sorry, I am not sure I completely understand your argument. You expect the energy used for Tesla cars to more easily migrate to greener energy? Bitcoin mining is completely location independent and is able to migrate to cheaper (which as renewable energy tech improves will equal greener) energy much easier than an individual tesla owner can.

But burning silicon is even more dangerous than burning coal!

https://en.wikipedia.org/wiki/Silicon-burning_process

>When a star has completed the silicon-burning phase, no further fusion is possible. The star catastrophically collapses and may explode in what is known as a Type II supernova.

>The central portion of the star is now crushed into either a neutron star or, if the star is massive enough, a black hole. The outer layers of the star are blown off in an explosion known as a Type II supernova that lasts days to months.
I'm sorry to hear that you witness a mid-air collision -- I hope it wasn't completely fatal. In the UK, all glider pilots wear parachutes and the overwhelming majority have standardised on a collision avoidance system known as FLARM that is "glider friendly" (unlike GNSS) and can differentiate thermalling from colliding.

It's just an internal 16 channel GPS receiver with an external antenna and an altimeter that predicts the flight path and then transmits it - including a unique identifier - as low-power digital burst signals at one-second intervals. Other aircraft also equipped with FLARM receive that, compare it with their own flight path prediction, and also check for collision information with known data on obstacles, including electric power lines, radio masts and cable cars, etc. If a proximity warning is generated to one or more aircraft or obstacles, it bleeps like anything and generates bright LEDs that point in the direction of the threat. The display also gives indication of the threat level, plus the horizontal and vertical bearing to the threat -- and there are three warnings (iirc ~30s, ~15s, ~6s) -- it warns by time and not distance.

Is there anything legally wrong with manipulating crypto courses? Or even ethically?

The supposed main advantage of cryptos is that they are independent of governments and institutions, and their rules. And in this case, that's exactly what they get.

And besides that, without 'manipulation' (which I'd say includes any kind of marketing), cryptos would inherently be worth exactly nothing.

For the exact same reasons that Jim Cramer is not in jail, CNBC staff is not in jail, Marketwatch staff is not in jail, Motley fool staff is not in jail, Ken Griffin is not in jail, etc etc.

For the same reasons the people who tried to short and manipulate Tesla (and GameStop) into bankruptcy for gains didn't go to jail.

Also for the same reasons market makers and hedge funds like Citadel can still exist while blatantly manipulating the market every second of every day and deliberately shorting healthy companies into bankruptcy for gains.

All of the above parties are doing way way way worse than Musk in broad daylight. All Musk does is arguably pump and dump. The above parties pump and dump and are constantly wash trading, influencing/buying the SEC, buying media (CNBC "Tesla is almost bankrupt, sell now", etc) for pump and dumps, pump & dumping on Twitter (Cramer), naked shorting illegally, messing with order executions, HFT DDoS attacks on exchanges for profit and so on and so forth. All at the attractive cost of meaningless tiny fines (assuming they get fined at all) and 0 jail time.

Yes. The US financial markets are completely rotten.

Ironically, I feel that the crypto markets are much fairer. At least you can buy a real token directly and sell that real token for money on an exchange of your chosing. At least it's clear that Musk is pumping and dumping (as opposed to Jim Cramer on CNBC, who does exactly the same for hedge funds under the veil of "trustworthy media").

As a comparison: ever tried to get your hands on stock certificates for stock you own? Good luck with that. Can you point me to a broker where you can directly own a share? You can't. They don't exist. Can you point me to a broker that doesn't lend out the shares which YOU "own" to hedge funds? I know of some in Europe, but they are very rare. Can you point me to a broker that allows you to route your orders to the exchange of your choice? I can only name 1: IBKR. The vast majority of brokers get paid to route your orders to the exchange that is worst for you and best for whoever is paying off your broker. And then there's "cheap" brokers who offer "payment for order flow" where traders essentially pay a "trade fee" to whoever is paying for order flow (to give you worse execution than themselves).

I could go on and on and on.

PS: to be sure, I don't mean to turn this into whataboutism and to argue that Musk's pump & dumps are ethically OK because others are doing worse. The point I'm trying to make is that the US markets are essentially rigged and unfair. And claiming that Musk should be in jail for pump-n-dumping is fine, but then many others should be jail too. Preferably for longer and with way higher priority.

People uploading to the web are subject to standard laws - graphic content is already illegal in many cases, as well as against the terms of service of many websites. "You are uploading graphic content to the web? We call the police, nice and simple. And let the judiciary deal with it" is already what moderators do.

The problem here isn't that there aren't enough laws, it's that the scale of illegal content being uploaded is vast and moderators are unprepared, untrained and underpaid because their jobs are considered unskilled, low value labor. that is what needs to change.

"greaseproof pizza boxes, carryout containers, fast-food wrappers, and paperboard packaging"

So basically everything used to wrap fast-food is toxic. Buying yourself some glass tupperware containers and cooking at home, or eating-in at a restaurant with ceramic plates, seem like the only solutions.

The longer-term solution is for Governments to create a 'whitelist' of chemicals allowed for domestic use. We cannot keep playing whack-a-mole with endless chemical varieties which all turn out to eventually be toxic.
The ability for planes to follow these highly accurate common flight paths was a contributing factor in the Gol flight 1907 mid-air collision in Brazil [0]. (That, plus ATC clearing the two planes at the same altitude _and_ both having TCAS (Traffic Collision Avoidance System) switched off). William Langewiesche published a great long-form article about the disaster called "The Devil at 37,0000ft" that's well worth reading if that's your sort of thing [1].

Is it bad to not want to do something only because public opinion says not to?

I think if you think it is bad, then that implies a certain world view about absolute good and evil. The implication is that this is an evil thing, and only an evil person would want to do it, and so if the only reason they won’t do it is because of public opinion then that doesn’t change their inherent evilness.

But the other possibility is that the person making the decision believes it’s a good thing, or at worst a neutral thing, but are not willing to pay the cost once they find out how badly everyone reacted to it.

Maybe Musk thinks decentralised money is more important than the setback to climate change? Maybe musk thinks that crypto will become green over time and it won’t matter? Or maybe he just wanted to do a pump and dump. There are all sorts of things musk can think, who knows.

But either way, people got what they wanted.

I bet it's a feeling of, "I used to be able to right click -> view source on any web page and see source code I could understand and learn from. I can't do that anymore, which makes it less open."

I think you can and should assume good faith. However, the explanation about the environment seems dubious for reasons people have pointed out here. They didn't know about bitcoin's environmental impact? The people at Tesla didn't think about negative environmental impact being counter to their brand? Giving the benefit of the doubt and assuming good faith does not mean you have to be gullible.

> When you ask questions in-context, both you and your colleagues waste less time.

I wholeheartedly agree with this. If you can save an hour of frustration by having a 5 minute chat in Slack, why wouldn't you do that? Your team will be infinitely more productive. Yet I've worked with managers who prefer their team to figure everything out on their own, and perceive questions as laziness or incompetence. There is a balance with the threshold for asking questions, and it helps if the manager and their team either have the same balance, or some flexibility. If not, the working relationship is often doomed.

> some [cultures] are high-context communicators and read in-between the lines (like people from Germany) while other cultures are low-context communicators and require explicit and redundant communication

As an American who also studied communication, and has lived abroad for years, I'm definitely a low-context communicator, both in how I communicate to others, and how I expect them to communicate to me. While I understand high-context communication culturally speaking, I don't see how it can work in software engineering, unless your whole team had the same education, works with the same stack, and has worked on the same apps for their entire careers.

Tesla didn't dump bitcoin. They only sold 10% of their holding, so any negative impact of their decision to cease acceptance of bitcoin for vehicle purchases, on the value of their bitcoin holdings, would outweigh the gains they made from pumping bitcoin and selling a portion of it.

People have successfully implemented proof of stake cryptos. Solana, cardano, avax,algorand just to name a few are all faster and cheaper than BTC or ETH (some vastly so), and don’t have the horrifying resource usage that comes with proof of work.

As far as I can tell, the fact that bitcoin/eth weren’t phased out for better alternatives tells me that:
* a significant usage of crypto is pure speculation/investment
* peoples identity gets tied to particular coins
* people care more about existing network than usability (eth vs solana, for example)

I have respect for the people in this space who are trying to do meaningfully new or interesting things, although its overshadowed by the wealth of blatant Ponzi schemes, memecoins, or copycats/scams just trying to make a quick buck.

If you are going to submit your thesis to HN as a story, you should be obligated to post a summary of it in a comment.

But people are really desperate to get others to read their thesis, and perhaps they thought they had done enough writing about it. I remember in grad school a friend I used to discuss some algorithms with finally submitted their thesis and gave it to me to read, which of course I didn't. Later on, I found out they put a foot/endnote it in offering me $100 as a check to see if I read it. It's hard, to work so many years on something, and then not have it read.
The Bitcoin mining farms in China are not rented out to western customers. They do not sell the raw processing power. They sell the finished product: mined blocks.

Only because it's not used.

This is like arguing we should switch from using cars currently on the road because they use energy, to cars currently standing in a garage, because we measured and clearly the parked cars use less energy than the cars on the road.

It's not even hyperbole, it's precisely equivalent and just as boneheaded as it sounds.

> A good mask will filter some aerosols when inhaling: but a cloth mask won't.

There's an issue with statements like that. "Cloth mask" is not well defined - are we talking literal layer of cloth, or the cloth-synthetic-cloth design recommended in some countries. Either way there's some gradient between 100% protection and nothing - cloth masks will still be better than nothing, but purpose-designed masks will outperform them.

This is not a trivial scenario to talk about, so the more specific we are the better.

The reactions on Twitter are crazy, the Bitcoin fanatics who never cared about other cryptocurrencies are loudy.

It's not sci fi. Hominids have evolved radiation adaptations here on earth already through natural selection alone: dark skin.

> The evolution of dark skin is believed to have begun around 1.2 million years ago,[9] in light-skinned early hominid species after they moved from the equatorial rainforest to the sunny savannas. In the heat of the savannas, better cooling mechanisms were required, which were achieved through the loss of body hair and development of more efficient perspiration. The loss of body hair led to the development of dark skin pigmentation, which acted as a mechanism of natural selection against folate depletion, and to a lesser extent, DNA damage. The primary factor contributing to the evolution of dark skin pigmentation was the breakdown of folate in reaction to ultraviolet radiation; the relationship between folate breakdown induced by ultraviolet radiation and reduced fitness as a failure of normal embryogenesis and spermatogenesis led to the selection of dark skin pigmentation. By the time modern Homo sapiens evolved, all humans were dark-skinned.

Why would you buy a $180 toothbrush when you can get a $20 Oral-B/Braun one? They're not even the cheapest because they are brand, and they're amazing, with no app and a simple design.

Don't you realize more expansive toothbrushes are the same, but with stupid apps and tracking sensors? Why would you want that?

Edit: Philips seems to be more prevalent than Oral-B in the US but the price ranges are the same. If you want the best tooth brushing experience, a 20 bucks electric toothbrush brush is fine. Any additional dollar goes to gadgety stuff
