Of course no sane person would spend ten years writing "All work and no play makes Jack a dull boy" over and over again". That wasn't the point. The labor theory of value says that the value of something is determined by

"Copyright demands that everyone pretend the value of someone's work is the product of that work, not the labor." Isn't it? If you spend ten years writing the Great American Novel, and I spend ten years writing "All

Strictly speaking it's the ISO C standard. ISO issues each new edition of the standard, and ANSI adopts it. This was reversed for the first standard, which ANSI published in 1989; ISO adopted it, with editorial changes, in 1990. The te

I wonder if the book itself is actually any good. My understanding is that authors often have little or not control over the covers chosen by their publishers. It's at least possible that the book itself is excellent, but I'm not

No, the behavior is undefined. That means, quoting the ISO C standard, "behavior, upon use of a nonportable or erroneous program construct or of erroneous data, for which this document imposes no requirements". A conforming implem

If the behavior is undefined, there is no wrong result.

Your code: int a = 5; int b = a++; has well defined behavior. The first line initializes a to 5. The second initializes b to 5 and sets a to 6. (The language doesn't specify the order of the two operations of assigning a v

What can be optimized out depends on the context. If you write: int i = 0; i = i++; and never use the value of i, the declaration and assignment are likely to be optimized out. (The behavior of the assignment is undefined, so t

Agreed. As a programmer, the solution to "int a = 5; a = a++ + ++a;" is to decide what you result you wanted, and write code that will produce that result, and probably to pass options to the compiler that tell it to detect this k

UUID v7 relies on knowing what time it is. Speculation: The most likely scenario for a UUID v7 collision is if UUIDs are generated during a system boot sequence, before the system clock is set to the current time. It's always 1970 some

It's not even possible to pass too few arguments to a function in C unless you go out of your way to write bad code. You can write a function declaration that's inconsistent with its definition in another translation unit. Declari

That doesn't do much good if you set `EscapeChar` to `none` in `.ssh/config`. I find it convenient not to have to worry about accidentally entering escape characters. YMMV.

I see a huge semantic gap between assembly language and C. An assembly language program specifies a sequence of CPU instructions. The mapping between lines of code and generated instructions is one-to-one, or nearly so. A C program specifie
