What is everyone's favorite function / formula? Mine is n/(n+x) It has a bunch of interesting aspects: As n gets bigger, it goes from 0 to 1. When n equals x, it is 0.5 As n gets bigger, the diffe

Van Gogh wrote that with The Night Café he tried "to express the idea that the café is a place where one can ruin oneself, go mad, or commit a crime". Were cafés different back then?

the net effect of AC is more heat Hmm... I don't think so. Yes, operating a fridge in your kitchen will heat up the kitchen. And yes, if that fridge is powered by burning coal somewhere, then it heats up the planet too. But s

Over time, will we cover all the roofs of the world with solar panels? I would guess that a solar roof generates enough energy to cool the rooms below it, no matter how high the temperature rises on the outside. So with climate change conti

I wouldn't expect C to just select one of the answers A and B have given. But rather to take in information from both answers and come up with a third one which is more than the sum of its parts.

How would that work then? How can they achieve the goals stated in the introduction like ensuring that users who play a game don't cheat? How would this technology prevent one kind of automation but not the other? The site also gives a

As I understand it, this would mean I cannot customize my reading experience anymore. As I could not run my own code on websites. For example, this is how I read HN: https://twitter.com/marekgibney/status/155148356

Chess. So many stories around it. So many interesting openings I tried. So many metaphors for real life. So many interesting characters in the history of chess. So many interesting books about it. Coincidentally my favorite is "My 60 M

I wish there was a competition to find out which paper plane stays in the air the longest. It would have to be an indoor competition where a machine throws the paper planes. I would be super curious which design wins.

For some reason, I never liked that all the code playgrounds have separate windows for HTML, CSS and Javascript. It makes it hard to grok what is going on. Does the CSS and JS get injected into the HTML? Is it loaded via injected <script

What you describe is similar to what beagle3 described. A world where patterns exist and slowly fade out. But that is not the reality of the stock market. See my reply to beagle3 for two ways to counter this view. Specifically to your point

You describe a world where you can watch the pattern slowly fade out and stop when it is gone. But in reality, there is noise. Say you start exploiting the pattern. You buy on Tuesday and sell on Friday. After 3 weeks of doing so, you lost

You don't know if "anyone else" already noticed the pattern. That does not reflect in the historical prices you can see. It will reflect in future prices which you can't see. And waiting for those does not help either. Y

The unintuitive thing about the stock market is that you are not trying to predict a system unrelated to yourself. But you are trying to predict other people's behavior. People who are just like you. So when you notice a pattern - say

Which post? I think this is a misunderstanding. Booking Holdings and Expedia Group are two different, publicly listed companies.

Existing appstores like the ones on iOS and Android mostly target casual use cases, mobile devices and on-device software. Not "buy once" experiences for work via software as a service. They also do not offer a unified experience.

When I up the loop size by a factor of 10, Python takes 10x longer. So I don't think the compile time plays a role here. Similar for the PHP version. python3 loop.py 3.450s time php loop.php 0.469s So PHP is 7x fa

Is Python's "values don't change, they get replaced by new ones stored elsewhere" approach what makes it slow? I would like to see some micro-benchmarks which pin down the bottlenecks. For example, this minimal benchmark

Depends on who does the comparison. And what is important to them. The Microsoft investor might say "I'm fine with the price going up and down a bit in the short term. Reducing that is not worth it for me to miss out on 50% of the

My first question would be: Do "best investors" actually exist? The title implies that some investors are better than others. But I have not yet seen any data driven argument in favor of this theory. There are so many investors on
