HAIL Researcher Marc shows up for the undefined problems. Next week at @icmlconf, he’ll explore them live at his talk, "Foundation Models for Automated Trading," Monday 7/14, 8 AM PDT. We'll be at booth 401 all week. Come say hi! #ICML2025

The Standard: upscale fine dining Undefined: elevated casual HAMBRGR: laid-back and fun!

Love yourself 🌹

Luxeed, the EV brand co-developed by @Huawei and @CheryAutoCo, unveiled its new car logo yesterday. The X symbolizes the unknown and the undefined, reflecting Luxeed's aim to break convention with a pioneering spirit, it said on Weibo.

Undefined Behavior (UB) Can Time Travel Fact: In C, undefined behavior doesn’t just mean "crash" or "weird output"—it can retroactively invalidate your entire program. The C standard allows compilers to assume UB never happens, so they can optimize assuming it won’t occur. This can lead to bizarre effects where UB in one part of the code changes behavior earlier in execution. If x + 1 overflows, the compiler can assume the condition is impossible (since overflow is UB) and optimize away the entire if block or even unrelated code before it! Why It’s Hardcore: Compilers like GCC or Clang can reorder or eliminate code based on UB assumptions, making debugging a nightmare. Tools like UBSan help, but catching all UB is nearly impossible in large programs. Deep Dive into this: Read about "time travel UB" in the LLVM blog or C11 standard (Annex J.2). It’s a consequence of the compiler’s freedom to optimize across the entire program.
