Pragmatach version 1.38 has been released
Here are the notable changes:
Commons Math is an Apache library which includes a variety of mathematical tools, including 1st and 2nd-order ODE solvers. In order to familiarize myself with the ODE solvers, I wrote a simple program to solve an RC charging circuit. The circuit has these parameters: R (ohms), the resistance of the resistor C (farads), the capacitance…
A couple projects I’ve been working on have a need for a REPL style console. I had written a simple framework for creating REPL’s, which is open-sourced here.
If you haven’t read this book, I highly recommend it. I discovered it in high school and finally purchased my first copy at the now-gone Duthie Books in Kitsilano. Without going into the details of the book, the author uses a simple Peano arithmetic called Typographical Number Theory (TNT) to illustrate some of his points. An example…
I recently found myself in a situation where mission-critical software was suffering from performance problems due to relying on a remote API which was both slow (as slow as 11sec / transaction), and unreliable. In this case, it turned out that there were multiple applications accessing this API, and every individual application was affected….

Recently, an OpenAPI spec has been published for it, so I decided to write a Java wrapper so I could control the spa myself, and monitor temperature with Prometheus and Grafana. The resulting code is here. The wrapper class “com.khubla.kspa.Spa” takes care of all…
