I love my GPD Micro PC

I bought two computers this year: a beefy Macbook Pro with M1 Pro and a GPD Micro PC.

Things I wish Git had: Commit groups

Everyone 1 and their dog 2 loves Git. I know I do. It works, it’s efficient, it has a brilliant data model, and it sports every feature under the sun . In 13 years of using it, I’ve never found myself needing a feature it didn’t have. Until recently.

Lossy CSS compression for fun and loss (or profit)

Late last year, I had an idea that’s been steadily brewing in my head. I’ve found myself with some free time recently (it coincided with vacation, go figure), and I’ve hacked together some proof-of-concept code. Whether or not it is actually proving the concept I’m not sure, but the results are somewhat interesting…

Web of Documents (2019)

It was called Xanadu . It was a grand, holistic vision: of documents that, once published, are available basically forever; of bidirectional links that could glue together not just documents, but parts thereof; of managing copyright and royalties. It was complex. And it never really came to fruition.

Clojure as a dependency

I have a shameful confession to make: I have long neglected an open-source library that I maintain, clj-tagsoup .

My mental model of Clojure transducers

I’ve been programming in Clojure for a long time, but I haven’t been using transducers much. I learned to mechanically transform (into [] (map f coll)) to (into [] (map f) coll) for a slight performance gain, but not much beyond that. Recently, however, I’ve found myself refactoring transducers-based code at work…

You already use Lisp syntax

How can I keep from singing?

This is a story of a most unexpected journey — one that is just starting. If somebody had told me four years ago that I’d be writing this today, I would have stared at them in astonishment or laughed dismissedly. Yet here I am, writing about a late-found hobby that has somehow become a very important part of my life.
