ROCm Core SDK 7.9.0 is a technology preview release built by TheRock. The Core SDK is a slimmed down version of the traditional ROCm release, focusing on foundational components for running high performance AI workloads on AMD GPUs.

TheRock manages dependencies between packages, so changes affecting several ROCm components can be coordinated automatically. Python releases built using TheRock can be...| AMD ROCm Blogs
/*Occasionally somebody will suggest that statically typed language X (Java, C#, Scala, F#, whatever) would be better off with C++'s "const", a type qualifer that supposedly makes objects immutable in certain contexts[1].

I learned about the new range API of std::optional from Steve Downey at CppCon 2025 during his talk about std::optional. To be honest, I found the idea quite strange at first. I wanted to dig deeper to understand the motivation and the implications. The first example I encountered was this: 1 2 3 4 5 6 7 void doSomething(std::string const& data, std::optional logger = {}) { for (auto l : logger) { l.log(data); } return; } This shows that you can iterate over an optional.
