If you already had to manage some degree of randomness on Java, chances are you got acquainted with the Math.random() methods. However, the previous method returns a double. Beyond very basic use-cases, another option has to be considered, in the form of the java.util.Random class. Random An instance of this class is used to generate a stream of pseudorandom numbers. — JavaDoc https://docs.oracle.com/javase/8/docs/api/java/util/Random.

Because of a course I prepared, I recently had a closer look at the java.util.function package in JDK 8, and discovered a couple of interesting design choices. A Callable and a Supplier are defined in the same way. But they are not equivalent.

Since I discovered Kotlin, I use it in all my personal projects. I’ve become quite fond of the language, and with good reason. However, there’s yet no integration with the Hybris platform - though there’s with Groovy and Scala. This post aims at achieving just that, to be able to use Kotlin on Hybris projects. Generate a new extension The first step on the journey is to create a new extension: ant extgen Choose the yempty packageChoose an adequate name, e.g.

IMHO, Kotlin is not about big killer features - although extension methods and properties could certainly be categorized as such, but about a bunch of small improvements that have deep impact. Most of them are not built-in into the language, but are functions offered as part of the Kotlin standard library. In this post, I’d like to go through a limited set of them, and describe how they can be used to improve the code.

This week was my last conference of 2017, Voxxed Day Thessaloniki organized by my good friend Patroklos. I started going to conferences some years ago. Going to a conference is an investment, whether in time or in money - or in both. You should me make sure to get the most out of that investment. In this post, I’d like to write down what I do to achieve that. Plan ahead The first thing to do is to get the list of available talks ahead.

Who is not aware that there’s a developer shortage? I mean, if you’re into the software industry, everybody is telling it every now and then - especially if you’re on the recruiting side. To handle that, companies come up with creative solutions - some are sponsoring education initiatives, or even creating their own. However, I think it’s not the right answer. Of course, there’s no doubt that there’s a shortage of good developers.
