Show me your flowcharts and conceal your tables ...

By Alvin Alexander. Last updated: October 20 2017

“Show me your flowcharts (source code), and conceal your tables (domain model), and I shall continue to be mystified; show me your tables (domain model) and I won’t usually need your flowcharts (source code): they’ll be obvious.”

I don’t have any major conclusions to share in this blog post, but ... what I was curious about is how Scala implements lazy val fields. That is, when the Scala code I write is translated into a .class file and bytecode that a JVM can understand, what does that resulting code look like?

A Perl script to delete binary files

By Alvin Alexander. Last updated: July 23 2016

As a quick note and a little bit of source code sharing, I wrote the following Perl script to delete all of the binary files it finds in a list of files it’s given. I named this script deleteBinaryFiles.pl, and it should be called like this:

deleteBinaryFiles.pl listOfFilesToLookAt

where listOfFilesToLookAt is a file that contains a list of filenames, with one filename per line.

Given that brief introduction, here’s the source code:

A Java FIFO queue class

In my spare time lately I’ve been writing this Android football game, and for the game I needed a simple FIFO queue. I haven’t used Java much lately, and after a quick Google search showed things that were more complicated than what I had in mind, I wrote my own FIFO queue.
