The bookmarks on www.codever.dev are persisted in a MongoDB Server. Very often I find myself in the situation, where I need to modify or look for something in the mongo database. Experience has taught me that interacting with a system via shell commands helps me understand it better, and sort of brings me closer to it. Ok, so how to find the right mongo shell command?

In this post I will briefly describe the steps and issues encountered when migrating a Java EE REST API from JBoss EAP 6 to JBoss EAP 7 - this implies migrating from a Java EE 6/JAX RS 1.0 implementation to a Java EE 7/JAX RS.2.0 implementation. The trigger was the announcement from Red Hat regarding the general availability of their JBoss Enterprise Application Platform 7 (JBoss EAP) ¹. JBoss EAP 7 is based on Wildfly 10², so the code snippets showed along the post should work on Wildfly 10 too.

One of my main concern when I considered the migration from Wordpress to Jekyll was how would I be able to handle multiple authors, because this plays an important role in the website supporting our Coding Friend Program. Fear no more, I have found a satisfactory way to handle multiple authors with Jekyll¹ and in this short post I list the main points concerning that.

Not long time ago I have rediscovered an old friend - Bash¹ the Alias². We were never best friends until now. We got acquainted at the beginning of my computer science studies. I visited back then a course held by Cisco, “Linux Essentials” or something like that. The trainer mentioned at one point what were aliases and how handy they could be. Well 12 years later, and I still had not gotten that, until recently, when the alias presented himself in a new light to me. Since then we’ve been best friends. Read on to learn why.
