Renaming a pile of files in Flea is now a single edit. Change every selected name at once, in the card or in your terminal editor. Swaps just work, bad lines are caught before anything moves, and one undo puts it all back. Thanks muellan for #183!

You know that if you keep implementing all my suggestions within days I'll take that as encouragement to push for even more😉 Keep up the great work!

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/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 🧵👇

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.

I'm getting very close to publication of my latest book: The Programming Puzzles Big Book (Fun for ages 7-99)! leanpub.com/programming_puzz… This is your last chance to get it for the pre-release price of only $4.99 and help me find any remaining bugs. This is 400 pages of puzzles!

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=63GKRVb8…

What main learning curve do you remember in your journey to programming? For me it was "functions" when moving from C64 BASIC to QBasic. Next was "how to correctly iterate over a std::list" in C++98

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.

Understanding Ranges Views and View Adaptors Objects in C++20/C++23

In this article, we’d shed some light on the implementation of ranges::reverse_view and std::views::reverse. We’ll compare them to understand the differences between views and their adaptor objects....

For those interested, I made a graphical overview sheet of the range views a while back:
