How to enable HTTPS in a Spring Boot Java application

how to enable HTTPS in Spring Boot - Thomas Vitale

Setting up HTTPS for Spring Boot is very easy, all you need to do is performing   the following operations:

  1. Generate a key-pair using the RSA algorithm;
  2. Generate an X.509 certificate using the keys from the previous step;
  3. Import the certificate inside the JRE archive for certificates;
  4. Set up Spring Boot to enable HTTPS.

To perform the previous operations I’ll use these technologies and tools:

  • Java JDK 8 (1.8.0_72)
  • Spring Boot 1.5.3.RELEASE
  • keytool

The last tool is provided together with the JDK, so if you have the JDK installed  you have keytoolalready available. To check it, try running the command keytool --versionfrom your Terminal prompt. Note that if you are on Windows, you might need to launch it from the \bin folder. For more information about it, you can read the official documentation.

Introduction to WordPress Plugins

49 472 WordPress Plugins available on the official repository. That’s a huge number! And they are just the Plugins available on wordpress.org. They are much more, for example think about vendors that sell their own Plugins on their platforms or the thousands of Plugins loaded on GitHub, but never submitted to the official repository.

For many people Plugins are surrounded by mystery. It seems that WordPress provides us with a powerful magic wand to get anything we want. To turn WordPress into whatever we want.

What is a Plugin?

The shortest answer is: a package of code. More specifically, a package of PHP code. That’s it.

The simplest Plugin is made up of a single unique PHP file. For example Hello Dolly, a Plugin that you’ve probably never used, but you have seen it at least once, since it is delivered together with WordPress.

It’s important to understand how Plugins are related to WordPress itself. There are three major components: Core, Themes and Plugins. The Core is the application itself. Themes allow to display some data to users and to choose the look and presentation of your website. Finally we have Plugins.

Plugins are used to extend WordPress functionalities or to add new ones. At this point you can ask why not to directly modify the WordPress Core. Continue reading “Introduction to WordPress Plugins”

How to setup gdb and Eclipse to debug C++ files on macOS Sierra

Using gdb debugger on macOS is no longer easy since Xcode stopped using it and replaced it with lldb. On macOS Sierra there are several steps to follow in order to make it work.

Install gdb

The easiest way to install gdb is by using Homebrew: “the missing package manager for macOS”. If you don’t have it installed, open your Terminal prompt and write this command:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Once you have Homebrew installed, you can simply run:

brew install gdb

Now check gdb installation by running:

gdb --version

Take note of the version: you’ll need it later. Continue reading “How to setup gdb and Eclipse to debug C++ files on macOS Sierra”

Il Web ci rende liberi? Gianni Riotta e la dialettica della rivoluzione digitale

La copertina del libro "Il Web ci rende liberi?" di Gianni Riotta, pubblicato da Einaudi
“Il Web ci rende liberi?” di Gianni Riotta, pubblicato da Einaudi

Il Web ci rende liberi? è l’ultimo saggio scritto dal professor Gianni Riotta, che s’interroga sulla domanda che dà il titolo al libro e prova a fornire una risposta soddisfacente. È un’analisi brillante e coinvolgente, in cui Riotta considera tutte le categorie della cosiddetta ‘Rivoluzione Digitale’ con rigore e lucidità intellettuale, senza pregiudizi o affrettate posizioni di parte. Solo nell’ultimo capitolo, infatti, l’autore rivela la sua posizione e spiega perché non si è schierato con le teorie analizzate nel corso della trattazione.

Pur non rivelando da subito la sua posizione, il saggio non è freddo o impersonale, ma è caratterizzato dalle esperienze autobiografiche dell’autore, che costituiscono la base degli argomenti trattati. Riotta, infatti, scrive spesso di come ha vissuto le novità nel campo delle tecnologie della comunicazione, rivela le prime impressioni, perplessità e sogni sul futuro di questi nuovi strumenti. In questo modo coinvolge emotivamente il lettore, che percepisce come la Rivoluzione Digitale abbia influito realmente sugli individui.

‘Individuo’ è una delle parole chiave del libro. Più volte l’autore sottolinea il passaggio dal secolo delle Masse, il Novecento, al secolo dell’Individuo, della Persona: il ‘secolo Personal’. Proprio dall’individuo bisogna partire per intraprendere il percorso di comprensione del Web. Scrive Riotta: “Dobbiamo guardare a noi, gli artefici e artigiani della tecnologia, prima che al software e all’hardware”. Continue reading “Il Web ci rende liberi?
