I’ve recently become very interested in blockchain, and that, naturally led me to Ethereum and Bitcoin. From there, I got a little interested in online trading, but since I prefer not to have to think about trading, I started thinking about a trading bot. Part of the work I needed to do was write a Java API for Qaudrigacx. The API is here and is free to use under the GPL v3 terms.
I’ve always had a fascination with compilers. As a Java geek, I’m also quite interested in the JVM. In order to learn a little more about both, and as a way to contribute to the open source world, I decided to implement a compiler for BASIC. So, jvmBasic consumes BASIC code and emits .class…
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….
I recently had a reason to parse a large data set, for another project. I decided that an ideal “large data set” would be my Outlook mail saved archives. Sadly, Outlook for Mac doesn’t output PST files, it outputs OLM archives, which are, essentially, giant zip files full of XML. I was coding this all…
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…
I’ve recently been quite interested in Graph languages, not for Graph Databases, but for representing information, in code that is essentially “things” and “relationships”. For example, one perspective on Organizations is that they are simply representable as people, systems and the information that flows between them. Those three building blocks are, in theory, enough to…
I was recently asked to release some of my code to Maven Central, and therefore had to figure out how to do it. I’ve now released these khubla.com libraries: cBean Pragmatach antlr4test-maven-plugin OLMReader simpleIOC ParadoxReader The maven coordinates for each are documented on the github pages.
