How to add redirects to your GitHub Pages website

Sun, 23 Mar 2025 00:00:00 +0000

GitHub Pages is a fantastic platform for hosting static websites directly from your GitHub repository. It’s simple, free, and perfect for personal portfolios, project documentation, and small business landing pages. However, as your projects evolve, you might find yourself needing to move content, or even switch to a new domain. This is where redirects become essential.

Without redirects, users who have bookmarked old pages or found links elsewhere will encounter frustrating 404 Not Found errors. This can lead to a poor user experience and lost traffic. In this blog post, we’ll delve into why you might need redirects on your GitHub Pages site and provide a detailed, step-by-step guide on how to implement them effectively.

Why I migrated my personal blog from GatsbyJS to Hugo

Mon, 26 Aug 2024 00:00:00 +0000

Over the years my personal blog has undergone several iterations, each using a different tech stack. When I adopted GatsbyJS, I believed I had found my long-term solution as I was initially very happy with it: React is a very good and easy to use library to develop frontends, the Gatsby community is big, and there are plenty of resources or examples about implementing common frontend features.

However, maintaining the blog proved challenging over time. My limited available time clashed with the significant effort required to keep the framework updated.

This is the journey that brought me to ditch GatsbyJS in favour of Hugo.

The Optional anti-patterns in Java

Fri, 27 Sep 2019 00:00:00 +0000

Traditionally, Java programs have returned null as a way to represent that a value isn’t present. The version 8 of the SDK includes a new class which was made specifically to manage missing values.

I won’t describe the details of the Optional class, but very briefly it’s a container object which may or may not contain a non-null value. Therefore, it is possible to manipulate null values as if they were normal instances without necessarily having to perform a null check at every step.

In this article, I’m going to talk about experiences I gathered while working with Java and describe some anti-patterns I’ve seen about such class.

Use Android SDK Manager with Java 11

Sun, 09 Jun 2019 00:00:00 +0000

Since with the release 11 some deprecated packages used by the Android SDK were removed, it’s not yet possible to run it with the latest Java versions. As a workaround it’s possible to download the required classes separately and add them to the classpath, or install the latest supported version, java 1.8. This latter approach is the recommended one.
