A constant pressure isn't enough to produce power. You'd need a changing pressure.

Epic did intentionally break the rules here, but I definitely have seen stories on HN before where Apple would refuse to let an app pass review without providing a proper reason why, and some more shadier things. If they do decide they don't like a developer, that developer really has little recourse.

The difference is, now, thanks to humans, there are 1.4 billion cows. And a lot of the cows are fed things like corn, which makes them produce a lot more methane than a more natural diet would. A million years ago, you wouldn't have anywhere near this many ruminants.

What kind of flour has sugar in it? Most flours are a mixture of starches and protein from grinding up a grain. Starches take more work to digest than sugars, so they don't spike blood sugar levels as quickly.

I'm not sure there is any guarantee that a function that completes successfully hasn't changed the value of errno anyway.

It's a carryover from the MS-DOS days. One unfortunate part is that each program has to implement globs and any similar feature itself.

Rust's .len() on string does not give you the length in characters, it gives you the length in bytes. If you want the length in unicode codepoints, you need to do .chars().count(), but given things like combining characters, that might not be quite what you want either.

That seems unlikely. Parasites are pretty good at infecting their hosts, and for a long time, there wasn't really a good way of getting rid of them once they were inside you.

The gut has its own nervous system: https://en.wikipedia.org/wiki/Enteric_nervous_system . Usually the effects of antidepressants on the gut are considered an unwanted side-effect, but in your case it was the intended effect.

Fun fact: The latest Linux kernel will still run fine on a 486, and give you a somewhat useable experience. You just need to make sure to pick a distro that hasn't built its packages targetting newer instructions than what a 486 offers.

Except that with a black hole this small, you'll be pulled apart by the tidal forces long before you even reach the event horizon. If you want to make it across the event horizon intact, you need a much larger black hole, like the one in the centre of our galaxy.

It's easy to give something up when you don't understand the danger of losing it. And we live in times where it's easier to give up your privacy than ever before.

My guess is that the hacksaw wouldn't work particularly well, but the bolt cutters or anything else that just exerts a strong, steady force without much motion should work. At that point, it shouldn't be any stronger than just regular aluminium.

For comparison, you could have someone who isn't colourblind wear the glasses for a bit, and ask them if the reds appear orange to them.

Even if we completely stop all manmade CO2 emissions right now, there still is too much CO2 in the atmosphere already. Actually removing the CO2 from the air in some way will be necessary if we want to stop global warming from getting even worse.

Thank you for writing this book! I'm currently working on a music creation program based on modular synthesis, and I expect the filters chapter of your book will really come in handy.

The second email address uses the Cyrillic small letter O, which renders the same as the Latin small O in almost all fonts. You can see this in your hex dump, too: Instead of a single o, your hex dump shows two bytes for the second character in the second email address.

I used the subscript 2 unicode character (U+2082). As far as I know, HN's formatting doesn't include anything to do subscripts. (At least, https://news.ycombinator.com/formatdoc does not mention it.)

One thing that comes to mind is https://en.wikipedia.org/wiki/Kinetic_isotope_effect , although this seems to mostly affect elements that only have a few protons, like hydrogen or oxygen. Still, it adds up enough so that replacing most of the water in your body with heavy water (D₂O) would be fatal.. But, you'd have to drink exclusively heavy water for a long time to actually reach a toxic dose.

Bach's work is in the public domain, which means anyone can make their own recording. But, any recording of Bach's works will still automatically have its own copyright, unless it's intentionally dedicated to the public domain too. The great thing about a public domain recording is that anyone can take it and use in any sort of artistic or even non-artistic endeavour, without having to worry about the usual "Contact the copyright owner, hope they will grant you a license that's not too expensive."

The thing is, without some sort of barrier, they would be completely swamped by the public trying to get them to record these, and then would be practically forced to stop doing it.

That's 28 years on-ship time, but about 2.5 million years for an external observer in Andromeda or the Milky Way. If you want to make a return journey, then 5 million years would have passed on Earth by the time you get back.

I think it's because the wave propagation speed through the strings is much faster for compression waves, compared to the standard transverse waves.

Eventually, the hardware will break, so it's a good idea to plan for that. There are ways to interface with old hardware using new hardware, including special modern motherboards that have ISA slots, or USB2ISA converters

Of course, the price in the title is assuming you already have an oscilloscope :)

Are you ready to take responsibility for all the people that would either die or have their health damaged by the virus? Including probably a significant number of teachers, parents, and even a few children?

It's because the whole graph is a single canvas element, there's no selectable/searchable text.

I'm not sure how using an unsigned number would help, given that when it overflows you're still going to have some code do unexpected stuff anyway.

I'd say having special features is ok, as long as these criteria are met:

1) It's obvious the feature is being used.

2) The feature is easy to look up without knowing what it's called, just based on how it's been used.

3) It's easy to understand what the feature actually does, with the appropriate context.

There's no reason why ray-tracing can't work with bent normals. That's how Blender's "smooth shading" works, and Blender uses raytracing for rendering.
