unique_ptr

Chandler Carruth argues in a CppCon 2019 talk that C++ has no truly zero-cost abstractions. Using examples like unique_ptr, ABI constraints and compile-time costs, he shows that abstractions cost runtime, compile time or human effort.

Louis Brandy presents the most common and infamous recurring C++ bugs seen in Facebook's huge codebase, including shared_ptr data races and operator[] pitfalls. He explains the surprising complexity behind seemingly simple code.

Herb Sutter revisits basic C++ questions in light of C++11 and C++14: how to declare and initialize variables, pass values to functions, write loops, and use smart pointers. It covers auto, rvalue references, range-for, uniform initialization, lambdas, unique_ptr and shared_ptr.

Tom Scott explains YouTube's 11-character video IDs, which are base-64 encoded 64-bit numbers, and whether YouTube could ever run out of them. It covers counting systems and base 64 briefly.

Frans de Waal's TED talk shows videos of behavioral experiments on primates and other mammals that reveal empathy, cooperation, fairness and reciprocity. He argues these moral traits are not uniquely human.

Markus Triska tours Prolog's most distinctive features, including its use as a database and query language, rule processing, constraint solving and compile-time rewriting. It also covers concise meta-interpreters.

Edward Kmett speaks at the Boston Haskell meetup about type classes and the design tradeoffs of global coherence compared with other approaches to implicit instances. It covers why uniqueness of instances matters for reasoning and refactoring.

Carol Nichols' Philly ETE 2019 talk on what makes Rust unique. It covers memory safety, how editions let the language evolve without breaking code, and who relies on Rust in production.
