MutexProtected: A C++ Pattern for Easier Concurrency
In this post, we will discuss the challenges of programming with locks and how the C++ language offers some useful tools to make it easier. We will start with an example in C and then use C++ to improve upon it in steps. The example APIs are based on real-life APIs from the SerenityOS kernel.

A case against currying
Curried functions are probably one of the first new things you come across if you go from an imperative language to a functional language. In purely functional languages, the convention is to define an n-parameter function inductively by staggering the parameters: applying the function to argument #1 returns a…

Reflecting on a Year of Gamedev in Zig
One year ago, I started programming a puzzle game from scratch in Zig. While it’s too early to announce the game (more on this later in the year), I want to share some of the insights I’ve gained about gamedev in Zig so far.

The C++ Killers (Not You, Rust)
All the “C++ killers”, even these which I wholeheartedly love and respect like Rust, Julia, and D, help you write more features with fewer bugs, but they don't much help when you need to squeeze the very last FLOPS from the hardware you rent. As such, they don’t have a competitive advantage over C++. Or, for that…

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.

Functional Programming Self-Affirmations
Dmitrii Kovanikov writes posts about enterprise software development and functional programming, both entertaining and serious. I never used a functional programming language (such as Haskell or OCaml) at work, but several ideas from functional programming have become popular in mainstream general-purpose programming…

How necessary are the programming fundamentals?
I feel like there's a lot of misinformation around this topic and I've been hoping I could address that in a way that could be convincing even for those who can't stand hearing the word

The challenges of teaching software engineering
I've just finished teaching a four-day course introducing software engineering for the first time. My plan is to refine the course (I'm teaching it again in October), and it will eventually become the basis for doctoral training programmes in research software engineering at Oxford, and part of a taught Masters. My…

Move on to ESM-Only
Three years ago, I wrote a post about shipping ESM & CJS in a single package , advocating for dual CJS/ESM formats to ease user migration and trying to make the best of both worlds. Back then, I didn’t fully agree with aggressively shipping ESM-only , as I considered the ecosystem wasn’t ready, especially since the…

Strategic Scala Style: Principle of Least Power
The Scala language is large and complex, and it provides a variety of tools that a developer can use to do the same thing in a variety of ways. Given the range of possible solutions to every problem, how can a developer choose which one should be used? This is the first in a series of blog posts aiming to provide…

Switching from Common Lisp to Julia (2017)
I have written this post for developers in the Common Lisp community who asked why I am switching to Julia. It may only be relevant for the small set of people who use Common Lisp for scientific computing.

Log messages are mostly for the people operating your software
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…

Revisiting Prechelt’s paper comparing Java, Lisp, C/C++ and scripting languages
In 1999, Lutz Prechelt published a seminal article on the COMMUNICATIONS OF THE ACM (October 1999/Vol. 42, No. 10) called Comparing Java vs. C/C++ Efficiency Differences to Interpersonal Differences , henceforth Java VS C , which seems to have later (March 2000) been expanded into a full paper, An empirical comparison…

The costs of the i386 to x86-64 upgrade
If you read my previous article on DOS memory models, you may have dismissed everything I wrote as “legacy cruft from the 1990s that nobody cares about any longer”. It's time to see how any of that carried over through the 16-bit to 64-bit evolution.
