Hi, I'm Dave Liepmann


Most of my code is closed-source, but here is some of my public work.

I collaborated with Matt Huebert and Jack Rusher to create a web-based literate-programming REPL optimized for beginners, maria.cloud (GitHub). Watch me introduce the tool at the ClojureD conference, or peruse the presentation slides.

I built and maintain Uruk, the Clojure library for MarkLogic.

I needed a workout app, so I made one for iOS.

I created Tufte CSS and now maintain it in collaboration with Ed Tufte.


Read my k-means clustering exploration, or watch the talk.

In the hopes of helping out a fellow Anglophone foreigner living in Turkey, I share some tidbits of knowledge about Izmir.

Enough people asked, so I wrote up my morning warm-up routine.

I have thoughts about hydraulic fracturing.


In the late 1940s my grandfather spoke about his experience as a German Jew fleeing Germany and then returning as a member of the Allied forces.

My 'Urgro├čvater` Hugo Liepmann has the distinction of his own Wikipedia page. For insight into his life I found Georg Goldenberg's paper Apraxia and beyond: life and work of Hugo Liepmann fascinating; I can assist with finding the full text if you're interested.

I visited some Liepmann family graves in Berlin.
