A simple-looking piece of code which results in something other than a list of Integer values being stored in a List<Integer> object.

Some notes to self about inaccuracies in floating point values.

I recently needed to convert text files created by one application into a completely different format, to be processed by a different application. The source files did not have line terminators. In some cases, the files were too large to be read into memory (without causing resource problems). A small Python script to the rescue - during which I learned about callables and sentinels.

Parsing a CSV file is a simple task, with great library support. This short example uses Commons CSV, together with Java streaming techniques. It also uses an enum, a lambda, a static factory method, a method reference, and other techniques. In other words, a combination of different tools, with some notes to help me remember it all.

Quick note on the syntax for using control characters in bash commands…

Why is the data in one of my fields being truncated to 4,000 characters when I read from a data source or via a lookup?

Note to self about gathering statistics for a Linux process, with a bonus note on generating a large random data file as input.

Some basic notes on how to install Corretto onto a Linux 2 instance on AWS.

Thymeleaf uses the Apache Commons OGNL (Object Graph Navigation Library). But there is also SpEL (the Spring Expression Language). This is a quick note on the differences - and an example where different behaviors may trip you up.

Be wary of using hyphens (dashes) in Thymeleaf expression names, as these can lead to some surprising results.
