Latches in C++20
Latches and barriers are coordination types that enable some threads to wait until a counter becomes zero. You can use a std::latch only once, but you can use a std::barrier more than once. Today, I have a closer look at latches.

Emacs Lisp Readable Closures (2013)
I’ve stated before that one of the unique features of Emacs Lisp is that its closures are readable . Closures can be serialized by the printer and read back in with the reader. I am unaware of any other programming language that has this feature. In fact it’s essential for Elisp byte-code compilation because…

Methods for Array Initialization in Rust (2018)
Arrays in Rust are fixed size, and Rust requires that every element in an array is initialized to a valid value when the array is initialized. The result of these requirements is array initialization in Rust is a much deeper topic than it would seem.

Rust is not a company
Last year, as an occasional contributor to the Rust project, I did not think much about the organisational structure of the team behind the project. I saw a hierarchy of teams and groups, team leaders, etc. Just like any other organisation. This year, after getting more involved, becoming a library team member and…

Constexpr is a Platform (2020)
Let me share a useful insight with you: constexpr is a platform. Just like you write code that targets Windows or a microcontroller, you write code that targets compile-time execution. In both cases you restrict yourself to the subset of C++ that works on your target platform, use conditional compilation if your code…
