I love Ruby! I’ve used it every day for years and I’m not sick of it yet. It’s an easy language to love: it’s expressive, flexible and syntactically beautiful ; it has a unique combination of useful features like mixins , metaclasses and blocks ; it comes with a useful core library and comprehensive standard library …
Fortran is a language that is specialized for high-performance computing. Believe it or not, it's still alive and evolving.
When writing concurrent Rust you will encounter Arc and Mutex types sooner or later. And although Mutex might already sound familiar as it's a concept known in many languages, chances are you haven't heard about Arc before Rust. What's more, you can't fully understand these concepts without tying them to the ownership…
Dave MacQueen (with Robert Harper and John Reppy) has written a 100-page History of Standard ML . Here I offer my brief, personal and utterly subjective impressions of its early days, up to the deeply unfortunate schism that created what was then called Caml . Standard ML was a tragic missed opportunity. But even…
A few years ago I've written in some detail about the Y combinator, including implementations in Clojure and Python.
This is a poorly structured list of common questions and answers about OCaml I had to ask myself or have been asked often.
How I've eased into a new language, Go, as a Senior Software Engineer, and some initial thoughts on the language.
Recently, a new set of sorting functions has landed in Go's golang.org/x/exp/slices package [1] . These functions leverage Go generics to provide a more ergonomic API for sorting (without requiring users to implement sort.Interface ), and also deliver a nice performance improvement, as the CL demonstrates.
Lists play an important role in Lisp--for reasons both historical and practical. Historically, lists were Lisp's original composite data type, though it has been decades since they were its only such data type. These days, a Common Lisp programmer is as likely to use a vector, a hash table, or a user-defined class or…
I write a lot of reductions: loops that combine every element from a collection in some way. For example, summing a vector of integers:
Dmitri's blog about programming, Clojure, and software development
I've been using Elm since about one year back now. At the start of 2021 I began working with a client that had an existing Elm frontend code base and an early stage backend built in Elixir and Phoenix. This post will be about my experiences running face first into Elm. I'll be vague on some details as I can't share…
Binary lambda calculus ( BLC ) is a minimal, pure functional programming language invented by John Tromp in 2004, 1 based on a binary encoding of the untyped lambda calculus in De Bruijn index notation.
Go 1.20, which is expected to be released in February 2023, comes with a small change that can possibly improve error handling in applications which heavily use …
Memory safety is a hot topic, but what do we mean by it?
I’ve encountered Object-Oriented Programming when I was learning Python (which is my first language). I’ve struggled with it because the paradigm is not as o...
The upcomming standard C23 has a lot of additions to the C library clause. Most of them are small, some of them are big but optional.
A while ago I was working on a Common Lisp library that makes use of the Metaobject Protocol . I ran into a few edge cases around dependencies between classes and it took a while for me to figure out how to solve them, so I wanted to write down what I learned in case anyone else might find it useful. This post is an…
How does set theory help to understand type assignability and resolution in TypeScript?
A Python Extension is generally some code written in language other than python to extend the python ecosystem by exposing an interface compatible with Python API.Such extensions are generally in form of compiled code and loaded dynamically by the Python runtime ...
How the 46 kana letters map onto 80 Unicode code points and how katakana and hiragana compare.
Virtual Threads are an excellent addition to Java platform and here's how Clojure is going to benefit from it.
A book review of my journey through dependent typing.
Ruby can work asynchronously with just a Fiber Scheduler and a couple built-in methods - no frameworks are required! It's easy to use, scales well, and has amazing performance benefits.

Lisp REPLs are on the collective lips of the WWW lately and so I thought I’d add my little bit of chatter to the mix as well. 1
Why unsafe Rust is a complex and user unfriendly experience.
Out of all Lisps the ones I’ve come to appreciate the most are Scheme and Common Lisp.
