but you can't pass functions in C, you can only pass pointers-to-functions... and you can return them too.
the piles of stuff that C contains are the stuff of 20th century von Neumann architectures, the stuff that defines the undefined behaviors, and that's what has made C indispensible.
I'm not saying C's perfect, but you can't swap it out without replacing what it did and does.
"if a 0.0.0.0 packet falls in a forest, will it make a sound a 0.0.0.0 listener can hear?"
your link was to an informative but still sloppily written article and in this context, your summary of the article isn't clarifying.
to write clearly, people gotta stop throwing around the word localhost because at the level of n.n.n.n there are no names, only numerical addresses and localhost is a name, one defined in a text file: 127.0.0.1 points to, not localhost, but to the local host, always; localhost (the name) points to 127.0.0.1 iff it is defined to (which should be all the time).
what I learned from the article is that a local host server listening on 0.0.0.0 will listen to everthing it can hear. But the question context here is, where will a packet sent to 0.0.0.0 go?
The point that 0.0.0.0 is not routable does not answer the question because 127.0.0.1 is also not routable; however, 127.0.0.1 will arrive someplace, at the local host. The question is whether 0.0.0.0 will also arrive into "the pool o' packets", that place that packets arrive on the local host prior to their disposition being determined (a. routed out of the local tcp/ip pool o' packets, b. listened to within the local tcp/ip pool o' packets, or c. dropped on the floor) because routing isn't only what Routers do, it's what tcp/ip does within a local host. (and btw, the article also describes that 0.0.0.0 means the default routing of last resort address in the context of a route address, also not the same as a packet destination address)
if they had raised money by telling a story that they didn't believe to the VC's to raise money from the VC's, then they would have been guilty of something by their own words: but they didn't, and their point in saying that was they did not do that. Instead, they pivoted...
The money they raised in the ICO has the SEC upset, but not for the reason your example refers to, but simply for lack of registration.
the original question contained an unsupported assertion that the 90s were simpler: it's not a cop-out to challenge the assertion and to try to explain it.
the Veneti (ancestors to modern Slavs) lived around Veneto while the Etruscans lived in Tuscany. Not that there was not a lot more mixing and migrating over the years, but still.
