My son and I built a wooden boat based on plans from The American Boy’s Handy Book, which are similar to the instructions in a Scientific American supplement from 1876

I wrote a children’s book about woodworking with hand tools.

I was querying a Postgres table with about 4 million rows and writing some of the fields to a CSV. I knew loading the rows into RAM was unacceptable, so I used the MyBatis class ResultHandler to process the records. The code ran fine locally, but in production we were having memory usage issues.

I was writing a WSDL-first SOAP 1.1 service (server) using Apache CXF. I needed to directly access the XML DOM of the SOAP Header and Body, so I did not want to use the standard JAXB data binding. My solution was to implement a Provider using message mode. However, retrieving the SOAPAction inside the Provider’s invoke(SOAPMessage msg) method was not intuitive to me.

I prefer to not run web applications as root. authbind allows you to run the application as a user other than root, but bind to ports 80 and 443.

Creating a Java-based service on Linux that will start when the operating system boots and run continuously doesn’t require any extra libraries, despite many internet posts to the contrary.
