How do I see the movie 12 Monkeys (1996)?

tl;dr: I see a totalitarian regime that controls humanity underground, similar to Silo, and they control space-time, and they spread a virus in 1996 to make that happen. Introduction This movie fascinated me since I saw it for the first time on TV in 1998 or 99, if I m not mistaken. For me, since I

Using Gemini for Application development

Introduction This article describes the usage of Gemini to help write code for an application like Python or JavaScript. That s a hands-on experience with Gemini for programming for the last few weeks, writing tools (small tools, not large tools). This approach here is purely empirical (disclaimer). Disclaimer Again, this approach is empirical. Issues: The following issues

Developer Blog Post articles

In the last couple of years, I have been publishing articles at Red Hat s Developer Blog rather than here. So here is a list of some of the articles I have published: Java Container Awareness Troubleshooting with fault tree analysis and PIOSEE How does cgroups v2 impact Java, .NET, and Node.js in OpenShift 4?

You are better citing sources than not citing – or why AI may not help

Sometimes I write blog posts here and for other blogs, like this one: https://developers.redhat.com/articles/2024/03/14/how-use-java-container-awareness-openshift-4 People will use that as reference, and that s great.

Conteudo, em anos vendo e pensando a respeito, eu tenho DUAS interpretacoes possiveis para a novela como peça fictional de entretenimento: a- trata-se de paradoxo temporal e, que o protagonista Esteban é o proprio pai dele.

OCP build is an asset

Being able to use OCP build configuration is a strong feature that improves the speed of deployment by a long margin. Building images via docker/podman can be an very streamlined process, but build config directly on OCP provides a fast deployment procedure straight to be able to deploy pods/containers in such a way that the

Cpu and memory resources in kubernetes from java perspective

I think I already discussed this topic a few times here but it is interesting that requests and limits are N/A for java (JVM) perspective OpenJDK will use limit as the mark for cpus. And naturally, given the container s cpu values are static (except on k8s 1.27) so then the limits will be inelastic.

DG/EAP beta 8 with Helm Charts

Back on DG/EAP 7 we used to use template for Source to image deployments at some point. In fact I liked template deployment of course you need to import the templates and such, but I don t think it is bad from a functional perspective. And the Operator is so simple, it gives much more time

Avatar and plot driven movies

I love Avatar, both of them, great movie. Made by a Canadian. Astonishing images. Back in year ago when I was released, but still have impressive images. Pandora is amazing. However, the second has one main problem: it is 100% plot driven not character driven. That s not a spoiler, but be aware that the

I don’t know why my pod is crashing – Investigating pod crashes

Working with Openshift in a daily basis, I come with several situations where the pod crashes. Given my background on java, I will talk about java here. Let me list a few situations and the next steps pods crash with OOME The java process uses more heap than it was suppose it would generate
