Apache camel

Recently I had the opportunity to play with Apache Camel and Spring Boot. I found the result quite entertaining! If you haven’t heard the name before, it is an open source routing tool which can receive messages, process them and send them to other destinations. In my case, I was reading payment messages from one topic, storing them in a db and then scheduled request with a POST call to another server.

HTTP load balancing

When you hear the term load balancing, this can refer to many different things such as routers, TCP, UDP or http requests. Today we gonna discuss about the latter. Load balancing for http requests is the process of forwarding traffic as evenly as possible among instances of your server pool. Have in mind that your machines may vary in size, load or geographic region even so that’s not an easy task!

HUGO static site generator

I guess some of you have heard about HUGO and how it is a great tool for building static websites. Personally I have used it for creating this blog and also for my father’s company website ptaino.com. I don’t have any prior experience with other static generation tools so I am not in a position to compare it to other solutions like Jekyll. What I can share with you though is my personal experience after using it, why I love it and tips to get started.

JShell

For those who haven’t heard the news, Java has officially its own shell, named (obviously) JShell since Java 9. It is a REPL type of environment where you type your code in the command line interface and see the results immediately on your screen. This is a good way to test simple programming concepts and ideas without the inherited boilerplate verbosity, which JUnit or main function has. Also semicolons in the end are optional!

It was GeeCon Prague and the organization plus the quality of the talks was really good, I highly recommend it to everyone!

Java 10 + var = L.F.E.

New variable type named ‘var’ in Java 10? Have we started turning into JavaScript anarchists? Has its very substance been polluted by Kotlin enthusiasts? Should we all worry by this new “feature” (are we sure its not a bug?) or could there be any benefits from using ‘var’ in our code? Var is used for type inference in Java and helps reduce the verbosity of the language. This means you are able to omit variables’ type, as it will be inferred by the compiler by looking at the right hand part of the assignment.

'Don't Make Me Think' book review

After reading ‘Don’t Make Me Think’ from Steve Krug I felt like Daniel-San from the movie “Karate Kid”. One scene shows Daniel’s frustration, after painting mister Miyagi’s fence for four days straight without learning anything about Karate. His initial frustration goes away upon realizing his mastery of the fundamentals. So what does both the movie and book have in common? You guesses it right, its all about the fundamentals! Plus you get a bit of secret sauce…
