What is an Interface

Fri, 01 Aug 2025 06:26:18 -0300

Behavioral Polymorphism: The foundation of OOP.

The interface is the foundation of OOP (Object Oriented Programming).

It provides behavioral polymorphism: constraining a type by its behaviours - or more secifically, its method-set.

A “method” (as termed in OOP langauges) is nothing more than a procedure who’s first argument is a pointer to the object it is associated with. There is nothing special about a method.

Definitions

Poly: many
Mono: singular
Morphism: shape
Polymorphism: having many shapes
Monomorphism: having one shape

Polymorphic refers to the ability to represent many shapes.

Why People Love to Hate Go

Go is very idiosyncratic, approximating good ideas and relying heavily on data transposition.

In this opinion article I will higlight why I think people love to hate Go.

I’ll do so by contrasting Go to Odin. Odin serves as an excellent comparison because the syntax is similar in essence (both heavily inspired by Pascal and C).

Unlike Go, Odin actually gives you the good ideas in their completeness - without a complex type system or giving up any control, and without needing to fight the ideas for a decade only to finally concede.

Plato Desktop Client

Overview Link to heading

A cross-platform desktop game client built for Plato Team Inc., supporting Windows, macOS, and Linux. Though now discontinued, the project showcased a modern, multi-window architecture with a primary chat interface and independent game windows.

The application was built in Go, using the Gio immediate-mode GUI toolkit. It interfaced extensively with C and C++ libraries, including ANGLE (OpenGL ES), V8 (JavaScript engine), SQLite, and libwebp for image decoding.

Sprig Arbor Chat Client

Built by ~whereswaldon, Sprig is a client for Arbor, an open source federated chat platform.
Sprig is a cross-platform client supporting Windows, macOS, Linux, Android, and iOS.
It’s written in Go, using the Gio immediate-mode UI toolkit.

My Role Link to heading

When I joined, Sprig stored each chat message as an individual file on disk. This file-per-message model worked reasonably well on Linux, but resulted in severely degraded performance on Windows, where reading thousands of tiny files led to notably slow startup times.

Overview Link to heading

icnsify is a fast, lightweight utility for creating and previewing .icns files—the proprietary Apple Icon Image format—without relying on macOS.

I built the first version in a Swedish café in 2018 as my first serious open-source contribution. Since then, it has grown into a widely used tool among developers—especially those building cross-platform apps with Gio—to automate icon generation as part of their CI pipelines or local development.
