So! Now our asset processing pipeline is almost complete. But we’ve just traded dependencies against CLI tools, for dependencies against dynamic libraries:

From Inkscape to poppler

What’s next? Well… poppler is the library Inkscape uses to import PDFs.

Cool Bear's hot tip

Yes, the name comes from Futurama.

Turns out, poppler comes with a bunch of CLI tools, including pdftocairo!

Halfway through this article, I realized the “regular weight” on my system was in fact Iosevka SS01 (Andale Mono Style) (see Releases), but the “bold weight” was the default Iosevka.

I love diagrams. I love them so much!

In fact, I have fairly poor visualization skills, so making a diagram is extremely helpful to me: I’ll have some vague idea of how different things are connected, and then I’ll make a diagram, and suddenly there’s a tangible thing I can look at and talk about.

Of course the diagram only represents a fraction of what I had in mind in the first place, but that’s okay: the point is to be able to talk about some aspect of a concept, and so I have to make choices about what to include in the diagram. And maybe make several diagrams.

Don't shell out!

In this series, I change a critical component of this website’s asset pipeline from “just calling a bunch of external tools” to statically linking with everything I need to process assets. It involves autoconf, CMake, Meson, CI, pkg-config, and some code crimes.

A new website for 2020

Hi everyone. Has it been two months since I last posted something? Yes it has!

That seems like a nice round duration, so let’s break the silence with a few announcements.

I have a new website

If everything goes well, you’re on it right now.

Does it feel okay? Take a minute to accustom yourself to your new surroundings. Identify potential sources of fresh water. Gather some supplies with which to fashion a makeshift shelter.
