Is a "write if not exists" atomic operation enouhg as a concurrency primitive for database locks?

Terms evolve and now filesytem and "system of files" mean different things, I would argue that not supporting folders or many other file operations make something not a filesystem today.

by this logic the file "foo/bar/" correspond to the filename "f:o:o:/:b:a:r:/" (using a different caracter as separator)

I think it is fair to say that S3 (as named files) is not a filesystem and it is inefficient to use it directly as such for common filesystem use cases; the same way that you could say it for a tarball[0]. This does not make S3 a bad storag

One of our clients handles non-trivial usage with a setup that is not much more complicated. They use hosted db (like AWS RDS or MongoDB Atlas), an external service for some user data (sorta like Firebase to handle user accounts, paid/

Rice cookers are designed to reach a certain humidity level, you can choose how much under/over cooked you can make the rice by putting less/more water

maybe you could pre heat the water pour the rice for 5 minutes and then start fresh with new water.

I agree that they too often chose to be petty and have a strong negative bias. They also sometimes seems to believe that insults are arguments. My personal opinion of Musk is quite different[0], but I do believe that they are not factually

As far as I understand SpaceX plan requires dozens of launches in close succession with never-tested in orbit refill, while Blue Origin does not. For another view of some considerations: https://www.youtube.com/watch?v=OoJsP

Function names are scoped to the current namespace. This means that for local closures it is usually better to define functions as variables $closure = function(){}; instead of function closure(){}

I believe that for almost all rationals trig functions never return a rational so you must have some kind of rounding tecnique. An advantage of rationals is that you have much more freedom in handling how the rounding works, for example you

I feel like at some point the performance hit of using actual rationals (pairs of bignums) makes sense

Almost every "escaping the sandbox" is due to some kind of bug. Sure if the PDF standard exposed a "globalThis.runBlobAsNativeExecutable" function it would be worse, but it is still escaping the sandbox.

No, they are not executable by the OS (generally). Formats are on a gradient between "completely code" and "completely data" and PDFs are quite close to the "completely code" extreme'; I guess this is what

Honestly I would be more in favour of limiting car speed to 5mph

so phones would be unresponsive on all public transport, boats, ferries, for all car passengers, and maybe even in places with shitty GPS?

for any random trip it is far more likely that the car will be a better choice, but likely trip choice is a power law with most trips focusing on few routes. This to say that the purpose of trains is not to be better than cars at what car d

I am talking about what is a reasonable price for something vs its market price. As far as I know a stock has three useful uses: - you can sell it to someone - you can collect dividends - if the company is sold you get a fraction of the sal

I am not talking about the valutatio of the company but about the price of the stock. The valutation of a company is meaningful for loans and investments, but not directly for retail trading. If the stock pays 0 dividends then the only valu

I am not sure about the other companies, but Tesla has no plan to ever pay dividends to stock holders so (buyout aside) the only "rational" value for the stock is 0 independently of its valutation.
