Disclaimers: I really tried to write this with AI, but the slop was too much.

Not too long ago, I upgraded my computer and got a new Lenovo ThinkPad X1 Carbon (a great machine so far!).

In this tutorial I want to consolidate some practical ideas regarding OpenTelemetry and how to use it with Spring Boot.

The purpose of this article is to consolidate all difficulties and solutions that I've encountered while updating Java EE projects from Java 8 to Java 11 (and beyond).

In this tutorial I will demonstrate how to create a "simple" (yet practical) token provider using Payara realms as users/groups store, with a couple of tweaks it's applicable to any MicroProfile implementation (since all implementations support JAX-RS).

From time to time it is necessary to distribute SPA applications using war files as containers, in my experience this is necessary when: You don't have control over deployment infrastructure You're dealing with rigid deployment standards IT people is relu…

From field experiences I must affirm that one of the greatest and stable combinations is Java Application Servers + Reverse Proxies, although some of the functionality is a clear overlap, I tend to put reverse proxies in front of application servers for t…

In this mini-tutorial we will demonstrate the configuration of a pristine development environment with Eclipse, JBoss Tools and Wildfly Application Server on MacOS.

This easter I had the opportunity to catch up with some R&D tasks in my main Job, in short I had to evaluate the feasibility of using Kotlin in regular Jakarta EE/MicroProfile projects including: Language benefits Jakarta EE/MicroProfile API support, spec…

Background At the end of 2000 decade, one of the main motivations for DevOps creation was the (relatively speaking) neglected interaction between development, QA and operations teams.

General information Pages: 95 Published by: Amazon Digital Services LLC Release date: july 2018 About the author I should start this review with a personal comment about the author, Bruno as many Java developers know is one of the most influential leaders…

Today one of my favourite open source projects got a major release, now under Apache Foundation, welcome back NetBeans!.

One of the most interesting concepts that made Java EE (and Java) appealing for the enterprise is its great backward compatibility, ensuring that years of investment in R&D could be reused in future developments.

Some days ago I had the opportunity/obligation to setup a brand new Linux(Gentoo) development box, hence to make it "enjoyable" I prepared a back to basics tutorial on how to setup a working environment.

. . . or why my report is half empty in Centos 7.

Yup it's the time of the year when everybody writes about yearly adventures.

Yey!

I'm not accustomed to do "trip reports" of conferences, but I think this conference deserves the report.

In this "back to basics tutorial" I'll try to explain how to install properly Payara 4.1 on Centos 7 (it should be fine for Red Hat, Oracle Unbreakable Linux and other *hat distributions).

After a routinary JVM update I had the idea of getting rid of old JVMs by simply removing the install directories.

Devnexus is probably (and according to this video) the second biggest Java Conference in United States, hence one of the top ten Java conferences in America.

Recently I'm in the need to do some reporting development.

The last quarter of the year is maybe my favorite period of time, since 2012 I try to attend at least to one "big" conference and this year won't be an exception.

A year ago I talked about GuateJUG's Java Day Tour in this blog, one year has passed (time flies!)

Although my first development box at this time is an Apple PC, I'm pretty comfortable with Open Source software due technical and security benefits.

One of the most annoying things of using JBoss Developer Studio on OSX is the default configuration, specially the font size.

For me 2015 hacktivism is officially closed, this year I had the opportunity to attend my first Java One and met some of my development heroes, folks from another JUGs, being trapped at Patricia's hurricane (no kidding), and bring a huge amount of Java t-…

As I described previously, GuateJUG held a conference circuit promoting its yearly conference Java Day Guatemala 2015.

In GuateJUG we arrived to our fifth year, consequently I must start this post with a "thanks to everybody that made this possible (developers, advocates, supporters, sponsors, friends, family, and other-UG)".

Hi, If you're reading this probably you are one of my few twitter followers, so thanks for your visit.
