Go's Concurrency Examples in Java 19
There is no way for your operating system to know exactly how much stack space a thread will need so it allocates an amount on the order of around a kilobyte initially and then around a megabyte once the thread starts to be used. You only have around a bakers dozen gigabytes of RAM, so you can only have give or take…

Crafting Interpreters
We’ll spend the rest of this book illuminating every dark and sundry corner of the Lox language, but it seems cruel to have you immediately start grinding out code for the interpreter without at least a glimpse of what we’re going to end up with.

Compile time evaluation in Nim, Zig, Rust and C++
Evaluating code at compile time is a capability that most, if not all, compiled programming languages possess, even if it can't be directly used by the programmer, but rather applied as an optimization. In this post, we'll explore a bit how to execute code at compile time in Nim, Zig, Rust and C++.

The Hare programming language
Hare is a systems programming language designed to be simple, stable, and robust. Hare uses a static type system, manual memory management, and a minimal runtime. It is well-suited to writing operating systems, system tools, compilers, networking software, and other low-level, high performance tasks.
