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. This article is supposed to be a simple introduction…

LogJ4 Security Inquiry – Response Required
On Friday January 21, 2022 I received this email. I tweeted about it and it took off like crazy. The email comes from a fortune-500 multi-billion dollar company that apparently might be using a product that contains my code, or maybe they have customers who do. Who knows? My guess is that they do this … Continue…

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…

Strict Python function parameters
What do you think about when writing a new function in Python? The function name, parameter names, optional/required parameters, and default arguments are all on the list. Here is a simple Python f...

I'm making a Typescript type-checker in Rust
TLDR; I'm making a Typescript type-checker in Rust. Right now it supports a smaller subset of the type-system and exists as a fun side-project, but the end goal is a compilation tool we can use to make Typescript compilation go brrrr...

My Elm Experience
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…

Ten years against division of labor in software
"Software libraries suck. Here's why, in a sentence: they promise to be abstractions, but they end up becoming services. An abstraction frees you from thinking about its internals every time you use it. A service allows you to never learn its internals. A service is not an abstraction. It isn't 'abstracting' away the…

Bad Emacs Advice

Starting with microservices
Starting a greenfield project with microservices is easy. The promises are wonderful but often they are far from reality. This time I’ll share my experience on the truth about microservices when starting a project from scratch.

Are We Really Engineers? (2021)
This is part one of the Crossover Project. Part two is here and part three is here. A conference talk based on this work is now available here. I sat in front of Mat, idly chatting about tech and cuisine. Before now, I had known him mostly for his cooking pictures on Twitter, the kind that made me envious of…

Why static languages suffer from complexity
People in the programming language design community strive to make their languages more expressive, with a strong type system, mainly to increase ergonomics by avoiding code duplication in final software; however, the more expressive their languages become, the more abruptly duplication penetrates the language itself.

How do you visualize code?
The other day I was reading about the development of personal computers and the desktop GUI, and I was thinking about how comfortable we all have become with the analogy of the “desktop” for our personal computers. We place files in folders and keep them on our desktops. There’s a lot of physical action going on…

Who Watches Watchmen? – Integrating Elixir Applications with Systemd
A lot of application use systems like Kubernetes for their deployment. In my humble opinion it is often overkill as system, that offers most of the stuff such thing provide, is already present in your OS. In this article I will try to present how to utilise the most popular system supervisor from Elixir applications.
