Listening to game three of the National League Divisional Series between the Washington Nationals and Los Angeles Dodgers today on the way to the airport, I heard a startingly weighty statistic: The team that wins game three of a five-game series wins 77% of series! That’s one pivotal game!

I’ve been experimenting with clojure.spec on a new web project, as a way of validating data coming in from the client. We’re using JSON API as the lingua franca between the server and client, which adds a not-insignificant amount of ceremony and overhead to the JSON payload. So once I got one namespace’s endpoints spec’ed correctly, the obvious next step was to generalize it with a function that looked like this (edited for brevity):

Tonight I gave a talk at Clojure PDX on building desktop apps with Electron and ClojureScript.

Building QT and capybara-webkit has always been at best an exercise in yak shaving and at worst an exercise in wizardry, prayer, and laptop damage. For the most part I have been free from problems with it for a while, but a new problem cropped up the most recent time I upgraded my Ruby version and bundled a project that included it:

Yesterday I described my experiences implementing multivariate Gaussian distributions in Julia. I’ve since repeated the exercise in Clojure, for any time you might need to do such a thing on the JVM. I’m using core.matrix for array operations.
