I grew up fascinated by projects like GNUStep, Haiku, Etoile, Wine, and ReactOS. Engineering feats, all of them. They reverse-engineer or reimplement entire operating system APIs so that software written for one platform can run on another. And they almost always end up in the same place: impressive technically, starved for contributors, forever chasing a moving target they can never quite catch.

I never liked the state of the Linux desktop either. Not because it’s bad per se, but because it’s fragmented. A KDE app on GNOME looks alien. Firefox rolls its own everything. GTK and Qt will never agree on anything. Every toolkit draws its own widgets, manages its own text rendering, handles its own accessibility story. The result is a desktop that feels like a coalition of independent projects rather than a coherent system.

Building a vector map renderer in Rust with wgpu. From “everything renders as points” to a full style-driven renderer running on desktop, iOS, and the browser.

Why

We built our maps stack on top of Mapbox GL: the JS SDK, then native SDKs on the C++ core.

For static maps we wrapped the C++ SDK in a Python library (maparazzo). It worked but the C++ renderer leaked memory. OpenGL contexts kept state around after objects were destroyed. We tried pooling Map instances, reusing GL contexts. It helped but never fully solved it.
