If you are using Neovim to write/review C or C++ this plugin could be really handy: github.com/J-Cowsert/classla… 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 🧵👇

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.

Been playing a lot with CPM lately, and I must say, I'm VERY happy with how it's working out. youtu.be/dZMU3iAPhtI Mostly it comes down to there being no question at all about how dependencies were compiled, because they are all just Right There. Watch the video for cons

I finally managed to write a blog post again: | Configuring algorithms in Modern C++ | hannes.hauswedell.net/post/2… | #cplusplus #cpp @meetingcpp
When designing library code, one often wonders: “Are these all the parameters this function will ever need?” and “How can a user conveniently change one parameter without specifying the rest?” This post introduces some Modern C++ techniques you can use to make passing configuration options easy for your users, while allowing you to add more options later on.
