  Reducing undefined behavior in C

  Martin Uecker discussed how C's undefined behavior arose from the language's historical need to support diverse hardware and an abstract machine model. He argued that while undefined behavior helps compilers optimize and preserve portability, it also creates ambiguity and debate over what programs are actually allowed to do.

  A retrospective on Project Xanadu’s failures

  This retrospective argues that Project Xanadu’s vision for hypertext and transclusion was undermined by poor design iteration, limited practical use cases, and insufficient focus on usability. It also contrasts those historical constraints with modern development conditions, including faster tooling and much larger storage and compute resources.

  Canonical tests AI-assisted C-to-Rust translation on security-critical code

  Canonical is funding researchers at the University of Bristol to evaluate whether automated tools can translate large C codebases into Rust without changing behavior. The project focuses on security-sensitive components such as AppArmor and snap-confine, and combines language-model code generation with fuzzing, formal analysis, and symbolic repair to verify equivalence and reduce unsafe usage.

  Tail-call optimization in C is now practical in GCC and Clang

  The post argues that tail-call optimization in C was historically limited by calling-convention constraints and was not broadly available in older compilers. It notes that modern GCC and Clang can now perform the kind of tail calls needed for interpreter dispatch, enabling techniques such as direct-threaded code and large-scale snippet generation. The discussion cites Gforth and WebAssembly interpreter implementations as examples of why this matters.
