Have you been interested in trying out Apache JMeter? Nicolai Parlog presents a useful tutorial to help you load test your web app, create a test plan, execute it and benchmark your application.

Continuous integration techniques are useful not only for project development, but also for software infrastructures. In this video tutorial, we find out how to improve infrastructure quality, reproducibility and speed with an infrastructure-as-code approach.

Here we look at how to use the Java EE upgrade ADF to build a system of pop-ups that dynamically reacts according to the user’s interaction.

Using functional programming to generate an alphabetic sequence in Java 8 is a challenge. A challenge gladly accepted by Lukas Eder, who teaches us the ABCs of ordering with Java 8 – and not the lame way, duh.

REST APIs make our lives easier – but we’re still in the dark ages when it comes to making our APIs general purpose, portable and reusable. Ben Busse shows us the common pitfalls of hand-coding custom REST APIs and the architectural advantages and technical characteristics of reusable REST APIs.

If you haven’t yet grasped the basics of Python classes, here’s where you can learn about the purpose, the syntax and the characteristics of classes in Python in just five minutes.

No one wants to have to write a sonnet of code for every single time you need a piece of software to do a task for you. That’s why in Python you can use functions to get shit done faster.

If you’re thinking of taking a deeper look at Python, you’ll first need some answers. What’s it like to program with Python? What scenarios does it work best in? And where is it better than competitors like Ruby, Java and C++?

Any enterprise that can begin treating its infrastructure as code, opens itself up to major performance improvements with automated tests, code repositories and build servers. This excerpt from “Amazon Web Service in Action” introduces us to the basics of Infrastructure as Code.

After counter-ranting about NULL, Lukas Eder wants to look at another “special value” that might change everything for Java 8: Optional. Functional programmers love it, so its worth digging around to find out whether or not you should follow suit.

Java 8 streams are still new to some, but by comparing common constructs in SQL, you might be able to get your head around them. Lukas Eder explores common SQL constructs with their equivalent expressions written in Java 8 using Streams and jOOλ.
