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
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.
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 there̵
This week, during a workshop related to a Java course I give at a higher education school, I noticed the code produced by the students was mostly - ok, entirely, procedural. In fact, though the Java language touts itself as an Object-Oriented language, it’s not uncommon to find such code developed by professional developers in enterprises. For example,
I’m not Git expert and I regularly learn things in Git that changes my view of the tool. When I was showed git rebase -i, I stopped over-thinking about my commits. When I discovered git reflog, I became more confident in rebasing. But I think one of the most important command I was taught was git rebase --onto. IMHO, the documentation has room for improvement regarding the result of optio
Last week, I tried to make a Spring Boot app - the famous Pet Clinic, Java 9 compatible. It was not easy. I had to let go of a lot of features along the way. And all in all, the only benefit I got was improvement of String memory management. This week, I want to continue the migration by fully embracing the Java 9 module system.
With the coming of Java 9, there is a lot of buzz on how to migrate applications to use the module system. Unfortunately, most of the articles written focus on simple Hello world applications. Or worse, regarding Spring applications, the sample app uses legacy practices - like XML for example. This post aims to correct that by providing a step-to-step migration guide for a non-trivial modern Spring Boot application. The sample app chosen to do that is the
It sometimes happen that after a few years, an app is stable enough that it gets into hibernating mode. Though it’s used and useful, there are no changes to it and it happily runs its life. Then, after a while, someone decides to add some new features again. Apart from simple things such as locating the sources, one of the most important thing is to be able to build the app. Though it may seem trivial, there are some things to think about. Here are some a
