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 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 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.
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 recently had a chance to learn a little about Bioinformatics, and ended up browsing the NIH’s database of genomes here. 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…
