Furthermore, two structure, union, or enumerated types declared in separate translation units are compatible in the following cases: — both are declared without tags and they fulfill the preceding requirements; the pre

Wait, seriously? They are unique, sure, but the 6.2.7.1 quite explicitly states they are compatible as long as they're in separate files: Moreover, two structure, union, or enumerated types declared in separate translation un

Nah, you won't sell the cow like that. You need to add more reliance on the public CA infrastructure and third-party code signing. Also, "ask user"? Ask the TPM instead — I mean, why would the computer's owner trust the

Well, what else can it do, really? It has to boot with pretty much zero knowledge about the external world (maybe except asking the user for the current date and time). Sure, you can hardcode an outdated list of CAs (it's always outd

Ah, detached "while" as a replacement for if-guarded "break". A concept that, syntactically, can very easily be fitted onto ALGOL/Pascal-like languages but not onto the C-likes: loop stmt1; while condA; stmt2;

No, I understand that. I just find it deeply ironic that when an interrupt/signal arrives, pretty much the only thing you can do to handle it, is to raise some flag, then leave the handler and continue doing whatever you were doing i

There is also a charming statement in POSIX standard that If the signal occurs other than as the result of calling abort(), raise(), [CX] [Option Start] kill(), pthread_kill(), or sigqueue(), [Option End] the behavior is undef

Well, there is apparently no evidence that he was "far right" either. So far, investigators haven't found any evidence on social media or other writings by Crooks that might help identify his motive for the attempte

Yeah... I've recently had a chance to compare how fgets is implemented in both GNU libc and musl, and, well. With glibc, it was a challenge to even find where the fgets's code actually is.

Most files aren't contiguous on a disk either, you know. Which makes inability to punch wholes in the middle of the files without having to read/write huge chunks of data quite annoying, especially when you write a linker or an ar

Y'know, makes me wonder why Democrates didn't disband ICE and CBP when they had control over the Congress and the government. I mean, they knew those agencies would be used in precisely this way, yet did nothing anyhow.

There is a book "The People's Republic of Walmart: How the World's Biggest Corporations are Laying the Foundation for Socialism" describing how e.g. Walmart (there is also Amazon now) does its own large-scale planning. I

Of course you can. E.g. the steel production in the US has been government-planned (well, DoD-planned) since the WW2, and it's not even that big of a secret, just not something that's mentioned often.

Well, maybe sometimes you need to format lots and lots of RFC 822 timestamps, or some other format that explicitly includes day-of-week.

So you propose to replace the nation states with corporate governments. Okay, two questions: who gets to make the laws, including the property laws? and who gets to enforce those laws?
