From Julia to Rust
I've been more serious about learning Rust recently, after dragging on with passive learning for a while. My first real programming language was Julia, and I know other Julians interested in Rust. I've written this article for those people in mind, because Rust and Julia are good performance sparring partners, but…

Implementing a LLVM Micro C compiler in Haskell
In this series, we will explore how to write a compiler for a small subset of C to LLVM in Haskell. Our language, Micro C, is basically a small subset of real C. We'll have basic numeric types, a real bool type, pointers, and structs. At the end of the series, we'll have a beautiful executable, mcc (Micro C…

An Intuition for Lisp Syntax
Every lisp hacker I ever met, myself included, thought that all those brackets in Lisp were off-putting and weird. At first, of course. Soon after we all came to the same epiphany: lisp’s power lies in those brackets ! In this essay, we’ll go on a journey to that epiphany.

Functional Programming in Go with Generics
Functional programming is an increasing popular programming paradigm with many languages building or already supporting it. Go already supports some of these features such as first-class and higher order functions and enabling functional programming.

Methods for Array Initialization in Rust (2018)
Arrays in Rust are fixed size, and Rust requires that every element in an array is initialized to a valid value when the array is initialized. The result of these requirements is array initialization in Rust is a much deeper topic than it would seem.

Ruby 3 JIT can make Rails faster
I’ve wondered Why Rails becomes slow with JIT for a long time. Today, I’m pleased to share my answer to the question in this article, which…

Undefined behavior in C is a reading error
Considering how important “undefined behavior” has become to C semantics and the ISO/IEC JTC1/SC22/WG14 Committee, the lack of any reference to it in the K&R ANSI book is notable and the description in the 1999 C Rationale was quite modest.

“I Could Rewrite Curl”
Collected quotes and snippets from people publicly sneezing off or belittling what curl is, explaining how easy it would be to make a replacement in no time with no effort or generally not being very helpful. These are statements made seriously. For all I know, they were not ironic. If you find others to add ……

A brief introduction to esoteric programming languages
This is the companion reference for A Brief Introduction to Esoteric Languages, my lecture for a friend’s college class. The video should be legible to other viewers, and the material here should be (mostly) understandable without watching the video. The Esolangs Listed roughly in order of appearance in the talk, with…

Teeing, a hidden gem in the Java API
Last week, I described a use-case for a custom Stream Collector. I received a intriguing comment on Twitter: There was a 'Moved Permanently' error fetching URL: 'https://twitter.com/Miguucm/status/1389258245886390292' Hats off to you, Miguel! Your comment revealed a method I didn’t know! So I decided to investigate…

Java's records, Lombok's data, and Kotlin's data classes
While all three remove boilerplate, the similarities don't go much further. Records have stronger semantics with important downstream benefits, which makes them better*. (* not always; depends on circumstances; excuse the clickbait)

Python vs Common Lisp, workflow and ecosystem (2019)
I learned Java and C at school, I learned Python by myself and it was a relief. After 8 years working and doing side projects in Python and JavaScript (mostly web dev, Django/Flask/AngularJS/Vuejs), I am not satisfied anymore by the overall experience so I’m making Common Lisp my language of choice.I am not here…

Why Rust strings seem hard
Lately I’ve been seeing lots of anecdotes from people trying to get into Rust who get really hung up on strings (&str, String, and their relationship). Beyond Rust’s usual challenges around ownership, there can be an added layer of frustration because strings are so easy in the great majority of languages. You just…

Rust is for Professionals
A professional programmer delivers value through the authoring and maintaining of software that solves problems. (There are other important ways for professional programmers to deliver value but this post is about programming.)
