In addition to this, according to issue #179, there are a few other caveats
I was recently in need of a way to pick up the list of installed software on a windows computer from Java. It was shrouded in a veil a mystery. There did not seem to be a functional call that I could make, which makes sense since Java is cross-platform and there is not universal way to pick up all the installed packages on an OS.
In fact, picking up all the installed packages on Windows seems be a bit cryptic. There are API calls you can make and I considered JNI. I suspect this might be a superior solution, but I haven’t tried it and I read that it may be slow.
After much research, I came across ListPrograms. My initial thought was to link to it using JNI. However, it seemed simple enough to warrant a rewrite in Java if I could access the registry somehow.
It didn’t take me long to put together a quick replica of behaviour. I skipped out the part about user installed programs because it isn’t relevant for me (yet).
I also missed out issues which will be around when running it as part of a 32bit VM within a 64bit OS.

This is a collection of the things I learnt developing a simple JavaFX app over the last month or two. My background is very much in Java EE with decades of experience building high end, high-performance ticketing systems. This means that my expectation from a development environment is relatively high. There are many optional components in here that I find worthwhile setting up at the start, but are not necessary
One of the most useful tools I have found while working with Java is maven. If maven isn’t a part of your build, have a look at it and re-evaluate that. I have no doubt that maven has saved me hundreds, if not thousands of hours over the last few years.
JavaFX Scene Builder
While this one has a bunch of issues and serious limitations, it can still be a helpful tool. It helped me get a handle on the components available and placing items.
I use junit5, but there are other options like test-ng which are equally good. I use Mockito for mocking, but there are many other options like PowerMock, JMockit, EasyMock, etc.
For UI Testing, you can use TestFX. I don’t like UI work, so haven’t done much work with this.

I can’t live without logging in any application. It can make troubleshooting much easier, particularly when you’ve deployed your app. log4j2 is the main logging framework out there. You can choose another one if you like, but I strongly recommend having and using one.
org.apache.logging.log4j log4j-slf4j-impl 2.11.0 org.apache.logging.log4j log4j-api 2.11.0 org.apache.logging.log4j log4j-core 2.11.0
If you have working the Java EE Environment, you have almost certainly come across Inversion of Control, particularly in the form of Dependency Injection. I love dependency injection. It helps with decoupling components and with testing. I looked at various frameworks including Dagger 2, Spring, Guice.
The fully static (compile time) nature of Dagger 2 means that it doesn’t gel well with JavaFX which is very dynamic.
I had worked with Spring many years ago and didn’t want to tangle with a behemoth for a small project. There are many components and loads of functionality in spring and if you building a large and complex project, it might be worth it.
Google Guice is the framework that I ended up going with. It does have some dependencies like Guava, but as it turned out, I Guava comes in handy for JavaFX anyway. We don’t need an entry in the pom.xml for this because of the following dependency.
Gluon Ignite was released by gluon labs to integrate Dependency Injection frameworks with JavaFX. In other words, it ties in the DI framework with the FXMLLoader so that it will load the correct controller instances. Since I am using Guice, I needed the ignore-guice module. If you add this into your pom.xml, it will also pull in google guice. Easy eh? 😉
com.gluonhq ignite-guice 1.0.2
If you don’t want to add another dependency, you could take a look at the code in this module. It’s fairly straightforward to integrate that manually into your app. It’s just easier to add in the dependency and let it do the magic
Event / Publisher / Subscriber Framework
It is likely that you will need an event framework or a publisher/subscriber framework. The nature of GUI design and work is that it is an easy and simple solution for a number of problems you will come across. Fortunately, we already have an event framework in place within Guava which is a dependency of Google Guice.
Don’t you love adding in a getter and a setter for each field? When you change your fields, don’t you love going in and updating all the getters and setters? How about defining the long, pita to type types with generics of variables that you are assigning from a method call? I mean the compiler can’t possibly figure that out by itself, right? How about writing out the toString, equals and hashCode for each class? What do you mean no, you don’t? You don’t love these tedious repetitive tasks of development? Good! You will love Lombok. Unfortunately, with Lombok, it’s not as simple as adding it into your pom.xml. Check out the install instructions on their website for you IDE etc. You also need it in your pom.xml.
org.projectlombok lombok 1.18.0 provided
There is some controversy around Lombok. There is a good post on stackoverflow that covers some of these things in a reasonable fashion.
Last but certainly not least, we have apache commons. This is a collection of libraries rather than a single one. You know all those bits of code you write over and over. Chances are that there is something in here that does it better and in a simpler way.
I stumbled across this game on gamejolt.com and tried it out. It sucked me in and I was smitten. See what happened.
#01 – Shipwrecked
We find ourselves shipwrecked on an island we don’t recognise. Let’s explore
#02 – Heading East
What’s over there in the east of the island? I get stuck, and think it’s all over, but there is more.
I am involved in the beta testing for playne, a meditation game. While I had meditated many many times in my life, I had never done it consistently. That is, until Playne.
I got curious about doing it as a series, and here it is
This episodes talks about getting started with Playne
#01 – Getting Started
Let’s get started with Playne
#02 – Settling in
Settling into meditating daily
#03 – Time for meditation
Making time for meditation is important
#04 – Layers of the mind
The mind is like an onion – so many layers and it makes you cry.
#05 – Level 2
We get to level 2
#06 – Positive Changes
Have you started seeing positive changes?
#07 – One Week in
That’s one week of meditating daily. How do you feel?
#08 – Stick with it
There are definitely benefits to sticking to meditating daily
The other day I stumbled across Origin All Access and saw that it had a bunch of games I wanted to play. One of these was Epistory, which had been in my wishlist for a long time. When trying the game out, I fell in love with it. It is absolutely a treat, so I decided to go through it as part of a let’s play.
#01 – Signal Fires
A meteor falls from the sky, and everything changes.
#02 – Forgotten Forest
We find a dark forest, forgotten and resistant.
#03 – Cold Shoulder
We witness another calamity, which once again changes everything.
#04 – Drowning Halls
Ice and water in these halls. Do we learn another language?
#05 – Spark
We stumble across Chapter 3 and another language
#06 – Creation City
Explore the rest of Creation City
#07 – Ice Mausoleum
We come across the Ice Mausoleum while exploring and delve into it.
#08 – Winds of Change
We run across Chapter 4 while exploring.
#09 – Shattered Isles
We go into the shattered isles and discover the fourth language.
“100 years in the future, something happened on Mars. Once frequently visited, it is now abandoned with some left behind. Explore and Survive the Red Planet.”
~ Memories of Mars
When I saw the game description on steam, I was intrigued. When they were giving out Beta keys, I volunteered and got myself a key. Following are videos put together from maybe around 10 hours of gameplay. Hope you enjoy
#01 – Exploring Mars
Random wanderings, musings and exploration of Mars.
#02 – Building a base
This is mainly the highlights of me figuring out and building a base on Mars 🙂
#03 – Beta 1 Highlights
Highlights from around 6 hours of gameplay over the Beta 1 Weekend.
