With new JDK, when you compile a spring-boot application you get a big jar which cannot be included as utility jar anymore.

The reason are a lot but, simply put, the new packaging system introduced with JDK9 require a strong separation.

On the current project, I had the need to extract the cpu limits from the deployment descriptor, sum them to check resource usage and print a report.

I need to do it on a lot of microservices, and also it can change in respect of the target environment.

Today I have an hard time using the @Profile directive for enable feature toggle on Spring, so I decided to write a small guide on it.

Introduction

Feature toggle is a way to write your code to be able to 'turn' on/off specific modules of your (micro) service. Because Spring Autowiring can 'discover' the right service for the right need, you can easily introduce feature toggle in an Inversion of Control engine like Spring.
I am not a super fan of feature toggle, but it helped me on more than one project. Also sometimes on production delivery you have some legal constraints (like enable a service not before a specifica date) and so a dynamic, parametrized run become a must.

I have one shiny mechanical keyboard I use on my daily job, under Windoooze and Linux bash

When I switch to my super-powered Mac on weekend, my muscle memory gets hurt because I need to switch sequence for Copy/Past keybindings, and also other minor shortcuts.

In the last year I did a lot of job interviews for frontend developers. Normally I ask to write a some codes, using some site like https://codesandbox.io or site with limited functionalities like https://www.onlinegdb.com/online_java_compiler
Because I am a Java hard-core sw-architect, my ReactJS questions are rather easy.

Hi, it was a very pleasant surprise to find out my maze demo code on the Commander X16 Web emulator. As you can image it was done collecting example on a popular site called 10print.org and it is nice because you can run it on possibly all Commodore 8bit computers (from PET to C/128 and to CommanderX16 too!). By the way the emulator is worth a try: for more example take a look to the official GitHub demo repo

I am playing to Divinity: Original Sin II  (D:OS2) which is the game done before Baldur’s Gate 3 (BG3) by Larian Studios

BG3 is a success despite its launch was anticipated in August to avoid head-to-head competition Starfield. If we compare the success of  BG3 with CyberPunk2077 launch failure, I think we can learn something about software developing PLANNING.

Divinity games are a tactical game with a lot of freedom, you can take things, combine them, and solve quests with different approaches (brute forces, talks with different paths,  etc). For instance you can try to open a door with a key, with a burglar kit, or bashing it until it is destroyed (more long but feasible).

There is very handy feature of SpringBoot which is called Dev tools. Dev tools enable hot reloading of spring-boot- based application every time your IDE recompile the code.

Because Spring Boot is often used with Microservices in mind, the reload is quick, and quite seamless.
