Rust Cryptography Should Be Written in Rust
Rust should be improved to provide the necessary building blocks that are needed to write cryptography code that is free from timing side channels and similar hazards. These facilities should not be restricted to code within Rust -provided or -endorsed libraries; anybody should be able to use them to publish a crate…

C++ at the End of 2022
I must admit that some previous years for C++ might feel a bit “boring” and “stable”. New features, new standard every three years, meetings, conferences… life as usual (apart from some additional World/Economy/public Health events…). This year seems different as it looks like a “breakpoint” in the history of C++… and…

JavaScript private class fields considered harmful
Today I mourn. What am I mourning? Encapsulation. At least in my projects. As a library author, I’ve decided to avoid private class fields from now on and gradually refactor them out of my existing libraries. Why did I make such a drastic decision? It all started a few days ago, when I was building a Vue 3 app that…

Using enums to represent state in Rust
Many Rust beginners with a background in systems programming tend to use bool (or even u8 – an 8-bit unsigned integer type) to represent “state”. For example, how about a bool to indicate whether a user is active or not? struct User { // ... …

Calling Rust from Python
I recently watched GOTO conferences' talk Calling Functions Across Languages by Richard Feldman. I’m afraid I have to disagree with using the term 'language' in this context. It’s a no-brainer to call Java from Kotlin or Scala or to call Java from Kotlin. Hence, in the rest, I’ll use 'stack'.

Interview about Austral, a systems programming language with linear types
Austral is a new systems programming language. It uses linear types to provide memory safety and capability-secure code, and is designed to be simple enough to be understood by a single person, with a focus on readability, maintainability, and modularity.

Ruby's private keyword is weird
Ruby's `private` keyword means something different compared to basically all other object-oriented languages. Most other languages don't even have a feature matching what Ruby calls `private`, but incredibly, Scala does, which it calls `protected[this]` (meaning
