I had the pleasure of living with one -- my dad ran The Bailey Information Exchange in Colorado. We had a satellite feed and a few lines for folks to dial into. I would get on a local terminal to play Legend of the Red Dragon and TradeWars,

It's not actually shifting a char, because integer promotion happens first. https://github.com/glfw/glfw/pull/1986#issuecomment-95578417...

That change came from the GCC steering committee, not the FSF.

The implementation of `fs::copy` uses `copy_file_range` on Linux, which does allow reflink optimizations.

You can't directly re-assign those developers, but you can try to influence their decisions. It's not only about the current developers either, but also potential new contributors that may be considering either project.

That's a funny example, because Rust's `String` does implement `Add` as concatenation! Many think this was a mistake though. https://doc.rust-lang.org/std/string/struct.String.html#impl...

It would be kind of amusing if this shortened code by re-rolling an unrolled loop.

On the range, the surrogates are actually 10 bits, 1024 possible values. The high surrogate is encoded in 0xD800-0xDBFF, and low in 0xDC00-0xDFFF.

Glibc malloc also limits the maximum according to ptrdiff_t, which is effectively the same as Rust isize.

I do it with a renamed `.git` and a bash alias `githome` that points `git` to the right place. This way it doesn't look like my home is a repo in normal use.

You can also use "cmake --build <dir>" to build regardless of which generator was used.

The dependency goes hyper -> h2 -> indexmap -> hashbrown, and indexmap is built on hashbrown::raw::RawTable.

For discovery, you could readdir, verify no case-sensitive overlaps, then stat a filename with changed case. Maybe compare inodes and number of hard links too if the changed name does succeed.

Perl 6 may be a contender, now so different that it's renamed to Raku.

Even that `ud2` is only there because rustc sets the `TrapUnreachable` flag for LLVM. In older versions you would get nothing at all, so calling main would fall through to whatever was next in memory.

You might need to cover openat too. I think newer glibc uses the openat(AT_FDCWD,...) syscall for all open calls.

Doesn't each wasm module get its own isolated memory? If so, then you could only shoot your own sensitive foot.

If Rayon were in the standard library, we would never be able to make breaking changes, whereas in a crate we can possibly release a Rayon 2.0. For instance, we might want to make some low-level changes in the way iterators split their work

In other languages, nothing ensures that those safe abstractions are actually used in safe ways. You can keep a dangling reference to a C++ vector, but Rust will make sure your references are valid, and you can only escape that with raw poi

FWIW Roland McGrath, the original glibc author, also works at Google. But of course not every possible person will be involved here, no matter how relevant.

Where do you draw the line on answering questions as a witness, versus refusing to answer as a potential accused person?

You can make wrapping writes look contiguous by mapping the same memory twice, one after the other. This is done in slice-deque such that the entire buffer can be viewed as a contiguous slice, regardless of the start/end positions. ht
