The screenshots demonstrate the trader purchased only $1,040 worth of options, not "$22,000" as claimed in the tweet. So the trader turned $1k into $475k. See the first photo in the tweet, the top left chart (45-day volume on the

It doesn't matter. The error is 0.03% only with one of the most simplistic approximations of 1 Bézier curve per quarter circle. Bump this to 2 or 4 curves, and the error drops to 4.0e-6 or 6.2e-8 ( https://pomax.github.io&#x2

I was not thinking of some highly advanced AI, just something ultra simple like: after ejection, attempt to pitch the plane to nosedive as vertically as possible. The intent being to to crash the airplane as badly as possible to prevent the

Actually my example assumed being in enemy territory. Nosedive the airplane for maximum destruction, to prevent the enemy from recovering anything useful from the crash site.

What Scoundreller meant is that if most of the controls are lost, then the few controls remaining could still be used to intentionally destroy the plane as much as possible. For example, the elevator (to control the pitch) might be the last

Sure, but that's not what parent said. He said it only runs on "intel macOS", which is false. It works on non-Apple computers as well. But I understand the miscommunication, parent meant to say "of the Apple computers, i

"It is unfortunate that it only runs on Intel macOS." Tails runs on most computers. It doesn't have to be a "macOS" (you mean Apple?). macOS is an OS, tails replaces the OS.

How much RAM do the devices have ? Why is Apple still mum on that basic hardware spec ? Weird.

In my usage, GNU units appears to be more featureful than qalc. For example I noticed that qalc lacks many definitions that I often use, such as energy density (eg. "gasoline"), mass density (eg. "golddensity"), energy u

For reference, the OLED LG G3 55-inch TV is rated for a power consumption of 375 W, but that rating typically indicates a worst case scenario (eg. maximum brightness, all-white screen, loudest volume, etc). So your 100 W figure is probably

Actually, your reference [1] states the opposite: Florida's "annual electricity expenditures are 40% more than the U.S. average"... which is caused by air conditioning. I think you meant to state that Florida's energy (n

I can answer 2 of your questions: - What is the probability that this asteroid will hit us? It's listed in the article: Impact probability 0.034, meaning 3.4% chance of impact. - What is the time interval where that probabil

Some slots machines may have a poorly designed RNG. For example it may have too little entropy, and its state may be calculated from multiple rounds of watching the symbols it displays. In one of Kevin Mitnick's books—can't recall

"That GDP does not increase my quality of life. " I agree. As I said in my first post: "prices of goods [eg. healthcare] are inflated in the US compared to similar goods in the EU". So concretely, if healthcare prices i

" GDP PPP can increase whilst your economy contracts. " Still, if PPP GDP increases, with all else being equal (eg. stable population) it would imply the standard of living is increasing. That is why PPP GDP captures a more accura

Note this chart shows nominal dollars, not PPP-adjusted. The EU has certainly kept up with the US when looking at PPP GDP from 2008 to 2022: US grew from $14.8T to $25.5T EU grew from $14.3T to $24.3T What that means is that the prices of g

It's about convenience. Refraining from taking certain car rides to reduce the risk is inconvenient. But for a wealthy customer, there is no difference between buying car seat A or B, but if A is $900 more and slightly safer, it's

A hypothetical HDMI-to-IP converter would certainly ignore hblank/vblank, and 8b10b encoding is only used on the HDMI link, not Ethernet. So parent's point stands: 1080p60 could be done in 3 Gbit/s.

I downvoted both you and the parent. While I agree with your argument, HN is not a place for disrespectful language as used by you and the parent.

"Should we pay outrageous amounts of money for stuff like this? It keeps people employed, which generates other positive economic effects, like buying houses and groceries. " Nonsense. You fell into the Broken Window Fallacy.

Tectonic plates are nearly permanently in a "sensitive arrangement", as you say. Compressive, shear, and tensional stress is the normal. Plates accumulate more and more stress over time, until a small trigger causes the plates t

Here is another way to think about these numbers: Antarctica was predicted to lose 140 cm of ice, but instead gained 4 cm. (This assumes the change of mass of ice would have been spread over the entire 14.2 million km² of the continent.)

You probably don't brush correctly: you need to apply sufficient pressure on your teeth so the bristles can scrub the enamel well enough. Or else there is no way your head has no visible deterioration after 5 months at 5 min per brushi
