What's New in POSIX 2024

In the 1950s, computers did not really interoperate. ARPANET has not yet happened (that would become a thing in the 60s), and every operating system was typically tied to the hardware that was meant to run on. Most communication actually happened over telephone, and no company was more present in that space than the…

Forsp: A Forth+Lisp Hybrid Lambda Calculus Language

Recently I've discovered a very interesting language / realization of the Lambda Calculus. I was unable to find any other language like it, which I find quite surprising.

C23: A Slightly Better C

One of the established and most popular programming languages is the C programming language. It is relatively easy to learn, and highly practical. Maybe surprisingly, the C programming language keeps evolving, slowly and carefully. If you have GCC 13 or LLVM (Clang) 16, you already have a compiler with some of the…

These changes are meant to help Rust become a better version of itself, enabling patterns of code which feel like they fit within Rust’s spirit , but run afoul of the letter of its law . I feel fairly comfortable with…

Four limitations of Rust's borrow checker

I’ve been using Rust for hobby projects since 2016 and have been working professionally in Rust since 2021, so I tend to consider myself pretty knowledgeable about Rust. I’m already familiar with all the common limitations of Rust’s type system and how to work around them, so it’s pretty rare that I have to “fight the…
