Hello World Wildfly Swarm 1.0 Final!

Today Wlidfly Swarm became 1.0 Final was announced! In my opinion, this is one of the most exciting Red Hat projects at the moment.

To celebrate this release, I made this quick video to the Generator tool.

Requirements:

Java 8
Maven 3

How to use:

Enter the group, artifact id and the APIs(dependencies) you want to use in the generator web page and click in "Generate Project"
Unzip the downloaded file and cd into the project directory
Run mvn widlfly-swarm:run
Use a browser to navigate to http://localhost:8080/rest/hello OR use the command curl http://localhost:8080/rest/hello
You should see the message "Hello from WildFly Swarm!";

Video

That's it, an 1 minute hello world! Now you can select the dependencies you need in your project before generating it and create your more advanced application.

Dancing lights with Arduino - The idea

I have been having fun with Arduino these days! In this article I am going to show how did I use an electret mic with Arduino to create a Dancing Lights circuit. Dancing Lights I used to be an eletronician before starting the IT college. I had my own electronics maintenance office to fix television, radios, etc. In my free time I used to create electronic projects to sell and I made a few "reais" selling a version of Dancing lights, but it was too limited: it simply animated lamps using a relay in the output of a 4017 CMOS IC. The circuit was a decimal counter controlled by a 555. 4017 decimal counter. Source in the image When I met Arduino a few years ago, I was skeptical because I said: I can do this with IC, why should I use a microcontroller. I thought that Arduino was for kids. But now my pride is gone and I am having a lot of fun with Arduino :-) The implementation of Dancing Lights with Arduino uses an electret mic to capture the sound and light leds...

Simplest JavaFX ComboBox autocomplete

Based on this Brazilian community post , I've created a sample Combobox auto complete. What it basically does is: When user type with the combobox selected, it will work on a temporary string to store the typed text; Each key typed leads to the combobox to be showed and updated If backspace is type, we update the filter Each key typed shows the combo box items, when the combobox is hidden, the filter is cleaned and the tooltip is hidden: The class code and a sample application is below. I also added the source to my personal github , sent me PR to improve it and there are a lot of things to improve, like space and accents support.

Genetic algorithms with Java

One of the most fascinating topics in computer science world is Artificial Intelligence . A subset of Artificial intelligence are the algorithms that were created inspired in the nature. In this group, we have Genetic Algorithms (GA). Genetic Algorithms To find out more about this topic I recommend the following MIT lecture and the Nature of Code book and videos created by Daniel Shiffman. Genetic Algorithms using Java After I remembered the basics about it, I wanted to practice, so I tried my own implementation, but I would have to write a lot of code to do what certainly others already did. So I started looking for Genetic Algorithm libraries and found Jenetics , which is a modern library that uses Java 8 concepts and APIs, and there's also JGAP . I decided to use Jenetics because the User Guide was so clear and it has no other dependency, but Java 8. The only thing I missed for Jenetics are more small examples like the ones I will show i...
