I don't think this is true. Archimedes screw is a similarly shaped helix but contained or partially contained in a tube so that it can move substances by rotary action. Using a helix as a simple machine is an old concept and probably p

The C abstract machine requires reversible transformations from pointer to integral types (7.18.1.4 in C99, 3.3.4 in C90, the first ISO standard). Practically speaking modern devices are in fact mostly flat, so you can of course do this, al

Even in cases of segmented memory architectures there is still a requirement that a void pointer be able to cast (reversably) into an integral type (7.18.1.4 in C99, 3.3.4 in C90, the first ISO standard).

> pointers by definition do not alias and it is impossible to make them alias This is equivalent to saying that pointer arithmetic is disallowed. Pointers are by their nature in the C virtual machine offsets into a linear memory space, s

For the life of me I can't get invested in these semantic games. The author even acknowledges Wittgenstein! This question only matters as regarding whether it has operational significance, and it's really hard to imagine a situati

I don't necessarily see where "customer consent" really enters the picture. Even if installing updates were optional, at some point you almost certainly want to install the updates, as it will contain bug fixes and enhancemen

No, there could still be inflation or deflation. Those terms refer to price levels denominated in a currency. If wages increase, then the "buying power" of the wages might not change, but the nature of savings and credit can be dr

This is pretty much meaningless. An N95, in order to be N95, must filter out 95% of 2.5um particles. For larger particles, this is almost certainly an lower bound as well, but for smaller particles manufacturing techniques and tolerances ca

I get where you're going, but unfortunately this is not apt -- the fungibility of coins was specific design point for Bitcoin (and for money in general, which is where the analogy surfaces). NFTs are by design and intention not fungibl

Sure; you want to accuse Tether of being a Ponzi Scheme? I think it fits the plain definition to some degree. The points that have to be dealt with are: 1. How much tether is held by Tether itself (and thus is a self-cancelling asset) vs. h

Gold I think is a good benchmark. But really any forex asset is just as good or better for a comparison. Gold has some portion of its value derived from decorative uses and numismatic purposes. People don't put 100 dollar bills on neck
