Scripting on the JVM?!? JBang and Kscript!
Wed Nov 10 2021Did you know that you can use Java and Kotlin for scripting? In this post I will introduce you to my favorite ways of doing scripting on the Java Virtual Machine (JVM), which is JBang and KScript. Some people may not enjoy Java projects as much because of all the verbosity (big project structures), so small scripts may make the languages more approachable and less intimidating. Being able to easily handle all external dependencies in the same file (no extra configuration files!) is also a big bonus. Lately I've heard from several people that they did not know about JBang, so I guess that might be true for KScript as well. Hope this post will provide you with some information on them, as well as good links to get started!
Read more..Programming Kotlin in Emacs (including KScript!)
Wed Nov 03 2021Some people, including myself, grudgingly used IntellIJ IDEA for Kotlin programming for a long time, maybe because we didn't think the Emacs tooling was up to speed. Well, it is, and we can finally use the best editor of all time (Emacs) to do Kotlin programming! Today I'm going to show you basic setup (and share some links), so you can also use Emacs for Kotlin programming! I made the switch this summer (reasons for waiting so long below), will you make the switch too?
Read more..The only book on classic JavaScript you'll ever neeed!
Tue Oct 26 2021Today JavaScript (JS) has evolved a lot and has many modern features we associate with other programming languages (according to the ECMAScript standards), like classes. In the beginning these features were transpiled (like compilation, but translated from one language to another) to classic JavaScript (due to browsers and other engines not having implemented the features). If you were like me, you wondered how this was done at the time (and you may even have had some ideas). Or you may be in the other camp, and think that it's not always necessary to use big transpilers and heavy features to solve simple problems. While JavaScript has evolved, I think there is a lot of fun and advantages to knowing more about the core language that started it all! JavaScript: The Good Parts by Douglas Crockford is the best book to learn about all that!
Read more..Spring Boot - Easy customizations for your applications!
Wed Oct 20 2021In this article I will show you two types of easy customizations you can do with your Spring Boot applications. One of them can be very useful, and one is mostly cosmetic for the benefit of those seeing the server logs. This article is language agnostic, so it can be used for all programming languages you might make Spring Boot applications in (probably Java or Kotlin).
Read more..Java ServiceLoader - What it is, and how to use
Sat Oct 16 2021ServiceLoader (aka Service Provider) is a feature that has been in Java since Java 1.3, but many people still don't know about it. The reason I think most people don't know about it, is that they use various dependency injection frameworks for the same kinds of problems. ServiceLoader can supplement these kinds of solutions, or be used as a replacement, you decide based upon the problem you are solving. Think of ServiceLoader as another tool in your toolbox. Some people like to think of it as a built in very simplistic dependency injection system.
