InfoQ
My InfoQ articles are listed in my profile:
Baeldung
Baeldung Article: Common Shortcuts in IntelliJ IDEA
I wrote an article for Baeldung on the keyboard shortcuts that we need to edit, build, and run Java applications in JetBrains' Java IDE, IntelliJ IDEA. Keyboard shortcuts save us time because we can keep our hands on the keyboard and get things done faster.
Baeldung Article: Running Spring Boot with PostgreSQL in Docker Compose
I wrote an article for Baeldung on running a Spring Boot application with PostgreSQL in Docker Compose.
Baeldung Article: Reducing JSON Data Size
I wrote an article for Baeldung on various ways of reducing the size of JSON in our Java applications. Java applications often use JSON as a common format for sending and receiving data. Moreover, it's used as a serialization protocol for storing data. With smaller JSON data sizes, our applications become cheaper and faster.
Baeldung Article: Removing Docker Images
I wrote an article for Baeldung on various ways of removing Docker images. A Docker image is like a Java class, and containers are like Java objects.
Baeldung Article: Using xz Compression in Linux
I wrote an article for Baeldung on how to use xz for compressing and decompressing files from the Linux command line. It included using xz with tar and speeding up archiving with multithreading.
Baeldung Article: Using gzip and gunzip in Linux
I wrote an article for Baeldung on how to use gzip and gunzip for compressing and uncompressing files from the Linux command line. It included using gzip with tar and speeding up archiving with pigz, a parallel implementation of gzip.
Tutorial: Better Java Projects Faster with JHipster and Docker
Explore the JHipster code
In the third installment of the "Better Java Projects Faster with JHipster and Docker" tutorial, we install or configure either Eclipse or IntelliJ for Spring Boot and Angular. Then we import the project and inspect the code that JHipster created for us.
Create your first JHipster project
In the second installment of the "Better Java Projects Faster with JHipster and Docker" tutorial, we first install all the software we need. Then we generate and run the JHipster application and explore it.
How JHipster and Docker saved my first Angular Java project
In the first installment of the "Better Java Projects Faster with JHipster and Docker" tutorial, I tell you about the many challenges I faced on my first Angular project last year. But thanks to JHipster and Docker, I successfully led the project into production and saved a ton of time. Let me teach you how you can get better Java projects faster, too!
