They propose a major language change: all functions would be noexcept by default, and only those explicitly marked with "throws" would be allowed to throw exceptions. Interesting paper, but it's not gonna fly in practice.

I tried quickly to find the list of supported systems, but the main documentation pages don't mention them. That said, pipe() is not "portable" either, so whether to use platform-dependent code for pipes or semaphores... no b

Actually I find this a very practical behavior. It allows me to have NULLs in columns participating in UNIQUE indexes. At least with indexes, it's very intuitive and useful.

You're right. But I've given up "language lawyering" a long time ago: I have a set of "rules of thumb" (like the one I just wrote) that exclude some technically valid programs, (but so be it) and that let me wr

This does not conflict with what I or the OP wrote; you're mixing up the vector and its contents. Moving from a vector can invalidate `data()`, yet references and iterators to its previous contents remain valid.

> when you std::move a string, the data() buffer would remain unchanged You cannot assume anything about the state of a moved-from object. AFAIK, the only valid operations are destruction and assigning something else to it.

The implementation is allowed to define UB to have a defined behaviour.

So which package manager is NOT horrible when it comes to handling conflicting dependencies? Esp. when combined with developers specifying wrong constraints for dependencies, either out of cluelessness or carelesness?

Yes, choosing EF Core is one of my biggest, if not THE biggest, regrets on the project I'm working on. Not because of the way it's packaged but because.. it's a heavy-weight ORM that stands in the way of using the database as

I'm surprised nobody in the thread mentioned using a TPM device when available. My 5-year old MB comes with one builtin, and probably all new ones have one. TPM also provides a limited amount of persistent storage.
