Embracing Modern C++ Safely, Book Review
C++11 has been around for around 11 years and C++14 for 8. From my experience, I see that even today, many companies struggle to use those standards in production in the most efficient way. As always, with new stuff came benefits, risks, and increased learning effort. Fortunately, with a new book written by top C++…

What is a programmable programming language? (2019)
When I was still researching this fabled obscure language called Lisp one thing people kept saying about it is that “Lisp is a programmable programming language”, but I could never figure out what they meant by that. It sounds like a smug buzzword or like a gimmick from an academic toy language. Lisp programmers have…

Formally Verifying Rust's Opaque Types
Introduction The other day I was reading this blog post covering existential types in Rust (also known as impl Trait or opaque types). In that blog post, the author makes the following claim. We’re going to have to take a slight diversion into type theory here because it motivates a result that is perhaps intuitive…

Const all the things?
Last week someone posted a /r/cpp thread titled “Declaring all variables local to a function as const”: Ok, so I’m an old-school C++ programmer using the language now since the early ’90s. I’m a fan of const-correctness for function and member declarations, parameters, and the like. Where, I believe, it actually…

Julia Macros for Beginners
Macros are a powerful and interesting feature of the Julia programming language, but they can also be confusing. Users coming from Python, Matlab or R have not come in contact with similar constructs before, and they require a different way of thinking about code.
