In the modern western world, a watered down version of Haṭha yoga is becoming more and more populair. Many describe the focus on physical posture and breathing techniques to be both pleasant and calming. In everyday’s world of stress and deadlines, a moment to relax and release can come for some not often enough. If you would ask your common developer about ‘release’ though, chances are high they do not talk of relaxation but of stress and hard work. I was thinking about this when I wanted to release a Gradle based Java FP library I am writing for my specialization.

Outside the Java commmunity, Java is often regarded as an old and verbose language. Though I love writing Java code, I kind of have to agree with this. New features are implemented slowly and looked upon by the language designers with thorough suspicion. For example, support for multi-line strings has been tried multiple times before Java got official support^[1]. If we are talking about verbosity, the Java language needs quite some characters to write a simple function. As I am specializing in functional programming in Java this year, I struggled a lot with this. Read along how I tackled this a little.

A while ago I was working on a Spring REST project and had a special wish. I wanted for one endpoint an exception thrown when someone requested it with an object with unknown properties. All the other endpoints with their rest objects should continue to exhibit the same behaviour. Let me share how I did this.

Nowadays, we usually work with frameworks when we want to set up a frontend application. We enter the terminal and enter something like ng new my-app or npx create-react-app my-app. The cli works it’s magic and sets up an entire application with a whole lot of stuff included. We’re good to go. But what if you just want to build something simple? What if you want to build an app that simply doesn’t have a lot of logic, and doesn’t need a complete framework, like a portfolio website. Or, what if you want to challenge yourself and see if you can build something worthwhile without a framework?

One of the first topics you will encounter when studying functional programming will probably be currying. For an imperative programmer not used to mathematical notations, chances are you will find the concept hard to grasp. Then let this be the day you will remember as the day you completely understood currying!

The time is right. Your work is done. The last letter of your Java code has been written. You let the IDE compile the code and a new running version of your app is ready to be released. You’ve done this a thousands times, there’s nothing new on the horizon. The question what lies beneath, what happens under the hood, has never occurred to you. Until now!

Until recently I’ve found unsubscribing to be a confusing subject. Apparently, you have to unsubscribe if you want to avoid memory leaks. But NOT doing so doesn’t always result in a memory leak. So what causes these leaks and how can we avoid them?

Welcome back to the final blog in de series "How to hack a box"! In this blog we’ll cover the basics of Privilege Escalation and see it in practice on the Blocky box from Hack The Box.

Welcome back to the blog series about how to hack a box! In the past few blogs we’ve gone through a few steps which gives you an idea of how you can hack a box. We went from the Introduction, to Exploration, to Gaining Access. In this blog, we’ll cover the basics of Enumeration.
