Here is a list of projects I worked on while on the sabbatical.
I had myDVDs, a LAMP based web application., set up on a Linux box.
(myDVDs) – http://freshmeat.sourceforge.net/projects/mydvds
It uses hometheaterinfo.com source for DVD data.
Then one of the updates caused the data load to fail. I then tried to move the application to a new Linux box and found that the database credentials were tied to the previous box. I took the PHP code and put together my own version. There was a lot of functionality I really did not use. I ran this version for several years.
I decided I wanted to create my own version keeping it as simple as possible. My requirements were to be able to list out all my DVDs, easy data entry unless I had to manually type in the DVD details, search the list to see if I already owned a DVD.
tools : liteIDE and sqliteman
I have two linux boxes on my LAN. One is an old one running a 32bit Ubuntu version so I would not be able to run Docker. The other I created as the eventual successor, a 64bit Ubuntu. I started to set up the Docker container. The Go binary sits at about 15 MB. Now this is where the added library needed for SQLite rears its head. I cannot use the base Docker to run the application because the library needed is dynamically linked. I could create a Docker image using an existing Ubuntu Server image jumping the size from 15Mb to over 500MB. I then searched and found an option. BusyBox Ubuntu would have most of what I need. I copied the needed libraries to their own folders in the Docker project. I now had a Docker image that was only about 20MB. I then added a data mount. The data mount is where the SQLite file resides and where I stage the latest version of the hometheaterinfo.com DVD list. Once I moved the Docker image from my laptop to my server it came up without a hitch. The only problem I then discovered was that the load of the DVD list was going to take over two days to complete. I then opted to just run the import to SQLite from the command line, which completed in few minutes.

Android App – DVD list
I then wrote an Android App to consume the JSON from from the DVD list website. It includes a configuration setup so I could change what computer it points. It has search by title.
Android, Java, SQLite,JSON
Android App consuming the CodeMash JSON
Just after completing the website and Android App CodeMash made the session data available as an API. I wrote a simple app to consume the data and load a local db and display the session data.

I worked on an Alexa Skill. I had to think about how the Amazon Echo handles the skill request. Basically it communicates through JSON. It dawned on me that I was trying to think about it as a app but really you have to think about it as a webservice. Now it all clicked, I made progress in creating the skill and then in the process also figured out a different way of handling my data. I decided to write it in python. Python has the ability to take an array and slice it. Which is exactly what I need. Then I should be able to take the slice use the join and have a string to pass to Alexa to speak. I got the skill working on my own echo. Much later Amazon offered developers a new Echo Dot if they publish their first skill. I had not tried to publish my skill but after working through the process my skill is now published and I got a new Echo Dot. The skill is called “Stretch Count” Alexa will count for you while you hold a stretch. I had found that my mind would wander an I would forget my place. This skill keeps me on track. I am not sure how helpful it will be

I decided to try my hand at Langton’s Ant.
Years ago to get back into Java, I wrote a simple video game. I had found out about the Godot game engine and decide to port the game to it. Godot has a scripting language very similar to Python. I made several videos of showing the progress.
I followed along with a video course I got in a Humble Bundle. The course was called “Python Artificial Intelligence Projects for Beginners.” I set up my main computer with the required libraries. I tracked down the data sets and ran almost all the code. Some of the processing was going to take way too long. I found it all interesting but I think it would too easy for someone to claim they are an AI expert and apply some of the techniques to get an answer, but they might not have the knowledge and experience to understand if the answer is even near to correct. I think over the next few years as AI increases in popularity there will be a number of people who “do AI” but not really know it. T
I started looking into programming ChucK. Chuck is a strongly timed and concurrent language for music and audio. It is similar to C/Java with enough differences to make you question everything. I found that following along in a ChucK manual was better than trying to piece a coherent strategy from the website. The manual is systematic where the website would be better for reference.
Some other projects I have done include a Android Podcast player. Coding some in PICO-8 , which is a fantasy game console. I wrote a check in application for my family reunion. Setup nginx for web development.
