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 in Java, so I needed a Java library to parse OLM files.
The resulting source code is here. Schema for OLM XML is here.
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.
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.
Back in the day, Paradox was a pretty amazing database. I recently had a reason to read some Paradox files for a friend, who had a client with a Paradox database. They needed their data out of the database to insert into something more modern. Googling for the file format of a Paradox DB didn’t…
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 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.
