If you're writing your own compiler, I don't think the Ferrocene specification will help you. It's basically an old version of the Rust Reference written out in a more bureaucratic manner. (I see a little new material, such a

Better documentation for method resolution than the Reference has would be nice. But at the moment the Ferrocene spec just says > 6.12:3 A method call expression is subject to method resolution with "method resolution" marked a

I think "Boundaryless Security" is decent. The first big step that systems people are calling "Zero Trust" have in common is that they don't trust devices based on the (physical or virtual) network they're conn

No, it's not as bad as that. The thing that's implementation defined is what happens if you don't explictly select either option.

Many (most?) combinations of a terminal emulator and a shell nowadays won't run pasted content without a further press of the return key. This is a consequence of "bracketed-paste mode".

I don't have any great objection to a database that lets you store a value of any type in any column. And if they want to say '3' + 5 = 8, I could imagine why that might be fine. But I don't think that's a good reas

I had a look at SQLite around the time sqlite3 appeared, and my notes say I decided I didn't like it because of the lax and sometimes inconsistent way it can treat its input. I thought I'd have another go at it today (sqlite 3.34)

That's true, but in most of those cases you don't need to be able to use numeric character-count-based indexes into the string (which is what the article is arguing that you don't need). You'd typically be happy if the p

Functions that index into the string-considered-as-a-sequence-of-characters can be meaningful, and sometimes useful, in cases where you know that the string contains only characters from some simple restricted subset. (You might know that &

This variant seems worse than the dataxis one. It's already a weakness of this "theory" that it leaves only the reference for documentation that's intended to be complete and correct, while also recommending that the ref

But it's hard to know whether or not this is true. There's no obvious reason to suppose that journalism is doing equally badly in all fields. I can ask someone who's an expert in a different field, and they might say "ye

One of the followups says: « unfortunately aiui the rust foundation cannot due to its nature as a 501(c)(6); you can't exclude people from a trade organization. » If that's true, maybe making a 501(c)(6) wasn't a bright idea.

There are some aspects of 'systems' programming languages that don't have a good history of being properly documented. Pointer provenance, as you mention, is one of them. The semantics of concurrent access to memory is anothe

The obvious reason is that the people with decision-making power actively wanted people to be locked in to Internet Explorer (and so Windows), so Tasman's improved standards-compliance was a negative.

I don't think Git "won" principally on technical merits. I think it won because VCS transitions are very painful so people wanted to use the system that they expected to end up being most widely adopted. Certainly that's
