Ngrok Spring Boot Starter - Tunneling The Easy Way

Ngrok Spring Boot Starter makes establishing a tunnel towards your developer machine as easy as adding a dependency to your Spring Boot project.

Ngrok is a tool for creating a secure tunnel from the public web to a machine behind a NAT or a firewall. It is considered the gold standard. Specifically it is used for exposing your local developer machine to the public net in order to test your projects or benchmark them. This is especially useful for quick prototypes, proof of concept or demonstration purposes. Also a type of tools, for instance Pingdom Website Testing, need to access your web project only over a public Internet addresses. So one such a way is to open a channel between your localhost and a public Internet address so that it can be accessed by all those services.

But since you are developer who is reading this, there's a very good chance that you own a VPS on Digital Ocean or Linode or elsewhere and can set up a reverse proxy on your local machine without needing ngrok at all. This setup is possible but you have to manually configure:

Making GraalVM Based Executables Easy with Liberica Native Image Kit

Liberica Native Image Kit is a utility for making native images for the JVM, letting you compile applications to executables using the GraalVM native-image compiler. As a refresher on what a native image is Native image is the executable binary file that contains your application, all its dependencies, and runtime components, allowing you to run your JVM based program on any supported configuration without the need for installing runtime or any setup. Native image is the easiest way to distribute your program and start it up faster. Native images have several advantages over JVM interpreted applications: Almost instant startup time Optimized resource consumption and smaller static footprint Does not require JVM for execution But why go for GraalVM over packaging your app with say Launch4J or javapackager? full article on i-programmer: https://www.i-programmer.info/news/80-java/15284-making-graalvm-based-executables-easy.html

Play The Flex Box Adventure

Coding Fantasy is a new platform for learning CSS, HTML and JavaScript by playing coding games. It already offers a free fun educational game for learning how to use the CSS Flex Box mode and here we look at what it entails. Coding Fantasy's creator Nick Bull has provided a well thought out gamified approach for learning about web development. The first game, Flex Box Adventure, uses three simple sprites - the Knight, Mage and Rogue- who must defeat the evil forces. Defeating them means placing your heroes at the same position as the evil ones by using flexbox's instructions like flex-direction,justify-content and align-items . Check the pictures below for an example of how it works: Challenge Solution #field { display: flex; flex-direction: column; justify-content: flex-end; } full article on i-programmer.info

Azul's Cloud Native Compiler - Why Share The JIT Compiler?

Azul's Cloud Native Compiler is targeted at organizations with multiple dev teams who share a common environment. Instead of compiling on their local machines, the process is offloaded to a cloud that shares a JIT compiler. Why is that beneficial? As we all know, when compiling code on the JVM there's a JIT compiler that turns the bytecode into machine code. Typically this happens locally at each dev's PC. What Azul offers is to offload this JIT compilation to a cloud-native Kubernetes-based compiler; this has distinct advantages over lone local compilation. Firstly the local resources are not stressed as much because they now engage less CPU and RAM resources. Another advantage is that as a lot of libraries and code is common amongst local dev machines, sharing their compilation in a common repository allows for caching, better dynamic resource optimization, faster compilation and less memory requirements. full article on i-programmer: https://www.i-programmer.info/news/
