Hi, I’m Alex.

I’ve put a bunch of things on the Internet, including:

• My personal blog, which covers a range of topics, from programming to photography, from colour theory to Chinese dictionaries.

• Everything I do for Wellcome Collection, a museum and library where I’m part of a team working on digital preservation, the website, and the online catalogue.

• A bunch of open-source tools and utilities, including for managing my scanned files, finding the dominant colours in an image, and web scraping for AO3.

• Silly art projects, like measuring data in floppy disks, or controlling a rocket with the <marquee> tag.

• My Twitter feed, where I share work-in-progress and think out loud about new ideas.

This site is a one-stop shop for everything I’ve made – it’s either here, or linked to from here. If you’re new, you might want to start with my blog or my list of projects.

I’m trans, genderfluid, and my pronouns vary. If we’re strangers, “they/them” is a safe default.

I hope you enjoy the site.

Blog posts

I write about anything I find interesting or fun – there’s plenty of programming, but lots of other stuff too. Here are some posts I’ve written recently:
