"rust is memory safe" mfers when i show them my disgustingly unsafe code that hooks several libc functions and transmutes like its nobody's business

i *urgently* need a blog post on how Microsoft managed not only to break libc `pow()`, but actually ship a build with a broken libc `pow()` to the Windows Insider canary channel

Microsoft solving the unsafe interop debacle by introducing a "safe" keyword is the funniest shit I've ever seen dude devblogs.microsoft.com/dotnet/impro...
![Every LibraryImport partial method must be marked safe or unsafe:
[LibraryImport("libc")]
internal static safe partial int getpid();
[LibraryImport("libc", StringMarshalling = StringMarshalling.Utf8)]
internal static unsafe partial nint strlen(byte* str);](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:ra3gxl2udc22odfbvcfslcn3/bafkreifgofhuoiiygup7lk6p72qc2sjatyfd5dfjeptkrmrfdam32mhpfe)

Really excited about what the team has accomplished here! Also, the post shares some really fun details of hardened libc++, huge credit to the #Clang, #LLVM, and libc++ community!
Excited to share our latest blog post on memory safety! We’re tackling spatial safety in our massing C++ codebase by hardening live++ by default. It adds bounds checks to things like std::vector, preventing a fair bit of out-of-bounds vulnerabilities: security.googleblog.com/2024/11/retr...

You can save a lot of disk space by removing *checks notes* libc.

Linux is pretty unique though in having a stable syscall interface. On other platforms Fil-C would have to provide a shim (possibly a second libc) which translates app-level libc calls to system libc calls

is @postmarketos.org the only distro that does Musl Libc + Systemd?
Does upstream systemd even support Musl Libc?

TIL libc provides a weird useless function called "index". I discovered it by renaming a local variable "index" (reasonable name for a variable) and having my code successfully compile but with a warnings saying "dude, you are comparing int to a function". And I was like wtf.

char32_t* cannot be compared and used against libc++'s __wrap_iter<char32_t*>.

I think its crazy that every application that uses GNU's libc library memory leaks. Its been an issue for 20 years.

systemd Lands Experimental Support For musl libc
Systemd today finally merged support for building against and using the musl libc library. This is a win for Linux distributions like postmarketOS, Alpine Linux, and others that use musl by default as their standard C library or offer it as an option...

i've modified wasi-libc and wasi-sdk (PRs pending) so that you always have the concurrency APIs (pthread_*, thrd_*, <thread>, <mutex>, <atomic>) available to you, even in single-threaded targets. this makes porting applications (especially C++ ones) much, _much_ easier!
Refactor stub pthread library and enable unconditionally by whitequark · Pull Request #602 · WebAssembly/wasi-libc
This PR changes the layout of the stub pthread library to match that of libc-top-half: splits it into (mostly) one file per function, and ensures the same API is exposed from both libraries, adding...
