The file may have been renamed or deleted since the fd was opened, and it might have been legitimate and on purpose, but there’s no way to tell what trying to resolve the fd back to a path will give you. And you need to do that because noth

To the extent that locking exists in posix it is various degrees of useless and broken. And as far as I know while BSDs have extensions which make some use cases workable Linux is completely hopeless.

> For example, Unix's `rename` syscall takes two paths as arguments; you can't rename a file by handle And then there’s renameat(2) which takes two dirfd… and two paths from there, which mostly has all the same issues rename(2)

The European green belt is an even starker example, it’s thousands of miles long but just a few tens to hundreds meters wide in most locations, yet its stability and continuity have made it a huge wildlife conservation area.

The question is why one idiom won over the other, which happened a long time ago. Because as the article notes on "any modern x86 processor" both xor r, r and sub r, r are handled by the frontend and have essentially no cost.

Given the claims relate to path traversal I assume it’s from (some) software treating http path trailers as FS paths, where a leading / would be an absolute path.

In my understanding of the Manley video, the materials change will only occur for Artemis 3, for which it will be irrelevant as that will not be leaving LEO.

Unions can be used as a somewhat safer (not safe by any means but safer), more flexible, and less error-prone form of transmute. Notably you can use unions to transmute between a large type and a smaller type. That is essentially the motiva

50 years of computing have proved pretty conclusively that less than that is wishful thinking at best. Large C++ programs, even with massive amounts of resources and tooling, can’t even get memory management correct.

I assume it’s either Antirez’s sds or a variant / ancestor thereof, yes. It stores a control block at the head of the string, but the pointer points past that block, so it has metadata but “is” a C string.
