Mission-critical applications require high availability. The goal of high availability is to provide users with consistent access to services or resources, minimizing the chances of interruption.

SQL has a long and proven history. It has survived the fuss around NoSQL.

Slow query times in large datasets are a common headache in database management.

TL;DR: I’m writing a new book on MariaDB for developers, and it will be available in the next few months.

I’m happy to announce that now the whole website is available en Español!

Today I completed the second migration of my website from Blogger to Hugo (previously from a drag-and-drop platform to Blogger).

Docker allows you to create isolated environments. And not only in production.

Over the past almost two years, I’ve had the incredible opportunity to work with the Marketing team at MariaDB plc as a Developer Advocate.

MariaDB is an open-source relational database management system that uses the Structured Query Language (or SQL) to manage and manipulate data.

Last week, I had the pleasure of giving a talk at the open source event organized by our partner Imagunet in Colombia.

I recently had the opportunity to attend the Cloud Expo Europe in London with our team at MariaDB, where we promoted SkySQL, our cloud database solution.

Can you tell us a little bit about your database and what makes it unique?

ChatGPT is truly impressive. You can instruct it to do all sorts of things when they can be communicated in plain text.

A proxy is a server software, typically installed in a separate machine, that forwards requests to servers on behalf of clients.

Database replication is a process that copies data from one database (primary) to another (replica).

Some months ago, I was lucky enough to get a bunch of Raspberry Pi minicomputers from MariaDB Corporation.

Do you want to start a basic HTTP server to serve the files in a directory on your machine using Java?

JPA stands for Jakarta Persistence API (previously, Java Persistence API). It’s an API specification for database connectivity in Java applications.

A database connection pool stores ready-to-use database connections that threads can borrow when they need them, and return when they finish the work with the database.

To run SQL queries in Java, you need a Connection object.

To open and close database connections in Java, get a JDBC driver for your database.

Recently, I joined MariaDB Corporation as a Developer Advocate. My job is to help software developers by creating useful content and enabling them to succeed especially with Java and MariaDB databases.

Some weeks ago I decided to accept a position as a Developer Advocate at MariaDB Corporation.

MariaDB’s ColumnStore is an engine that stores data in a columnar fashion.

Vaadin is a development platform for building web applications in Java.

I’m glad to announce the availability of my most recent book, Practical Vaadin: Developing Web Applications in Java published by Apress, a division of Springer Nature.

I had the pleasure to announce the Vaadin Community Award during Vaadin Dev Day Spring 2021.

I like to think about open-source involvement in terms of levels.

Hey reader! A short entry to announce and document my blog’s rebrand.

A couple of days ago, a good friend of mine asked me how to make her kid more interested in programming.

Ever since I joined the team at Vaadin I had wanted to showcase our technologies at a local conference in my home country, Colombia.

Although this example application is simplistic and no one should ever use microservices to implement an application like this one, it shows you how it feels to run this kind of applications and how to implement it using Spring Cloud.

In this video I demonstrate how to call a Java method that runs in the server from a JavaScript function running in the web browser:

Here’s a short excerpt of Chapter 9 Lazy Loading of my book Data-Centric Applications with Vaadin 8.

Vaadin is a set of tools to create web applications tailored to both, client-side and server-side developers.

I recently got some hard copies of my last book about Vaadin.

I have to embed YouTube videos or playlists frequently, so I decided to implement this simple tool to generate the HTML code of an embedded responsive YouTube video or playlist:

Vaadin Flow is a free open-source web framework for Java developers.

I’m glad to announce that my second book about Vaadin has been published!

During the last months, I’ve been researching and experimenting with microservices and Vaadin applications.

As some of you may already know, I started writing a book about Vaadin 8 for Packt Publishing almost a year ago.

Some years ago I published the Enterprise-app add-on for Vaadin. The most awarded feature was the CrudComponent class that allowed you could add a CRUD-like interface to any Hibernate entity by writing one line of code.

Finally! After endless hours of rehearsal, screen recordings, audio recordings, film recordings, audio-image synchronization, editing work, and do it all over again, we have published the first 6 videos of the Vaadin Tutorial series.

This is about Mr., W. J. a nice and friendly developer working for an IT company in a cosmopolitan city.

Code Complete is one of those books every developer should read.

Willing to learn Vaadin 7 in a funny way? Here there is an excerpt of my book Vaadin 7 UI Design by Example: Beginner’s Guide.

Don’t get me wrong. Comments are useful and not all of them have the olfactory purpose of the famous analogy I’m using in this article’s title.

And the winners are: Iskael Diaz Marquez Camilo Gonzalez Packt Publishing has two copies of Vaadin 7 UI Design By Example to be given away to two lucky winners.

I have used this two or three times in my life but it’s one of those simple (and useful?

I remember a couple of years ago, while working with some developers, one of them seemed to be irritated by seeing empty lines in source code.

Finally! I’ve managed to write a Maven POM for Enterprise App.

Some months ago, I got involved in a project where I needed to generate quite big reports (more than 1 million rows) extracted mainly from an SQL table growing at a very fast pace.

A few days ago, an Enterprise App user asked me if lazy loading is better (particularly in a buisiness application) than pagination.

I have been a ProjectLocker and Assembla user for years. They both offer excellent tools for software projects management.

As some of you already know, I will be making a big noise about Enterprise App and InfoDoc Pro next month.
