Most Minecraft servers are run on x86_64 based hardware. Ampere AltraMax chips run AARCH64…which is the non-ARM specific way of saying ARM64 instruction set.

Dependency Injection in Java
You might be thinking that this is a long solved problem. I think I have something a little bit different.
This is very similar to the C++ based one that I wrote long ago.

Continuing my attempt to update what I know about modding minecraft from 1.8 to 1.15. Based on my experience from this book;
Updating a Minecraft Mod: Part One
I have not touched the mod code I wrote for a couple years now. When Arun and Aditya Gupta wrote their book, the current version of Minecraft was 1.8. That was five years ago, and the current version is 1.15. Some things have changed. I want to document what I need to do to get my old mods running again on the newer version.
My starting point is that I have a working version of Minecraft and the comparable version of forge. Lets take it from there.

Many years ago, when I first started working at Red Hat, I worked up a package management domain model diagram. I’ve referred to it many times over the years, but have never posted or explained it in detail. Recently, discussions over image building software caused me to refer to it a few times. Here it is, with annotations below.

If I want to run software collections code without enabling bash and running interactively, I have to pass the whole command on the command line like this:
scl enable rh-maven35 "mvn package" |
I’ll need to use this form to run from Ansible.
Maven With Software Collections
I’ve been interested in the intersection of Ansible and Java development. To test this out, I want to build a “Hello World” maven App and use Ansible to drive the process to build, test, and deploy it. I’m going to use the Software Collections way of installing and running Maven to build a simple Tomcat Web Application as the basis.
Java on Port 443
I’ve been working on setting up a Java based SAML provider. This means that the application needs to handle request and response over HTTPS. And, since often this is deployed in data centers where non-standard ports are blocked, it means that the HTTPS really needs to be supported on the proper port, which is 443. Here are the range of options.

Java and Certmonger Continued
Now that I know that I can do things like read the Keys from a Programmatic registered provider and properly set up SELinux to deal with it, I want to see if I can make this work for a pre-compiled application, using only environment variables.
Running GUI Applications in a container with SELinux
As I work more and more with containers, I find myself wanting to make more use of them to segregate running third party apps. Taking the lead of Jessie Frazelle I figured I would try to run the Minecraft client in a Container on Fedora 25. As expected, it was a learning experience, but I got it. Here’s the summary:
