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…

I Built a Ruby Parser
Sorry, this post will read like a “dear diary” entry rather than some life-changing HN-worthy guidance. Back in November 2020, almost on a whim I started work on a new parser for the Ruby programming language. It was almost exactly a year after I had started working on my compiler project (I hope to write a longer…

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 German School of Lisp (2011)
The German school of Lisp is described by Kazimir Majorinc as a Spartan movement 1 in Lisp implementation. But let me be clear, the Lisps in question are not toys like the one’s littering the Lisp landscape (including my own ). Likewise, these Lisps are not libraries nor are they full-blown development ecosystems.

Zero Feet: a proposal for a systems-free Lisp
Some make the claim that "all languages depend on C"; 1 not only is this statement ill-typed, as implementations perhaps depend on other languages, and languages rarely do, but the statement would still be wrong if we correct it. Some will retort by writing parts of an implementation in another "system language"; more…

Golang Diaries: Generics
My coding time this year has been invested in Quamina , an event-filtering library implemented in Go. Just in the last couple of weeks I spotted an opportunity to bring Go’s shiny new generics to bear, and not just anywhere, but for a central data structure. I got good results, but the process was sort of painful; I…

Delimiter-first code
A new top-level syntax for programming languages is proposed to show advantages of this method. New syntax is arguably as simple, but more consistent, better preserves visual structure and solves some issues in code formatting.

What Is Rust's Unsafe? (2019)
I’ve seen a lot of misconceptions around what the unsafe keyword means for the utility and validity of Rust and its marketing as a “safe systems language”. The truth is a lot more complicated than a single pithy tweet can possibly sum up, unfortunately; here it is as I see it.

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…
