C++26 pack indexing lets you grab the Nth type from a pack without recursion. no more std::tuple trickery.

If you are using Neovim to write/review C or C++ this plugin could be really handy: github.com/J-Cowsert/clas… Just hover over a type or variable, press a key and see exactly how Clang lays it out in memory: offsets, padding, alignment etc. in a floating window.

The Pimpl pattern: heap allocate your implementation, write a copy constructor, write a move constructor, write a destructor, write copy assignment, write move assignment C++26: std::indirect<Impl> impl_; Done. The compiler generates everything 🧵👇

@SbastienLevy1 @ChShersh Unfortunately. If the rank is less than the rank of int, there’s a promotion to either int or unsigned int. It’s a real mess.

This is Algebrica. A mathematical knowledge base I’ve been building for 2.5 years. 215+ entries, carefully written and structured. 400k+ views over this time. Not much in absolute terms, but meaningful to me. No ads. No courses to sell. No gamification. No distractions. Just essential pages, aiming to explain mathematics as clearly as possible, for a university-level audience. Built simply for the pleasure of sharing knowledge. Content licensed under Creative Commons (BY-NC). Best experienced on desktop. If it helps even a few people understand something better, it’s worth it.

Posted a new video about std::chrono which provides an overview of what functionality was added in C++11, C++17, and C++20. Watch to find out how much of chrono your compiler supports. We were pretty surprised at what we discovered. #cplusplus youtube.com/watch?v=63GKRV…

@lefticus functions pointers classes/objects (encapsulation+invariants) inheritance+OO patterns STL design philosophy monads other functional patterns Pretty much in that order. Each of these concepts unlocked a new way of thinking for me.

@DefenceForceOrg @bowsamic @MittringMartin Precisely - My point was just that the better (safer) equivalent to the “by value“-version would be the “const&” version. No need to take something by non-const ref if it’s not absolutely necessary.
