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 recently had a reason to need a TELNET server and couldn’t find a Java library that worked for me. After a weekend of hacking, I now have kTelnet, an Open-source, BSD-licensed, TELNET server.

Inside the genome data for any particular strain of a species, you’ll find various files with file extensions like “ffa”, “fna”, “ffn” and “frn”. These are FASTA files. If you’d like an example, here’s…
Jasper is the JSP compiler inside Tomcat. For reasons, mainly of curiosity, I wanted to build a Pragmatach plugin which exposes Jasper. Pragmatach supports some template engines such as FreeMarker, ThymeLeaf and Velocity, but I thought Jasper would be a good addition. I chose to use Tomcat 6, mainly because Tomcat 7 uses Servlet 3.0. Pragmatach…
I recently had reason to get to know OpenAPI at work, so I decided to become familiar with it. I have a HomeSeer home controller at home, which exposes a JSON API, so I decided to write a Java OpenAPI server to expose the JSON API over OpenAPI. The net result is hsOpenAPI. It exposes…
