Blog de Dionysopoulos

I am Nicholas Dionysopoulos. I am a developer — mostly PHP but I occasionally dabble in Dart/Flutter and anything else I get my hands on. I hail from Greece.

I mostly known as the lead developer of award-winning backup and security solutions for PHP-powered sites and a frequent contributor to the Joomla! CMS.

1. Hibernation and Hybrid Sleep on Linux

   If you have a Linux laptop you probably wonder where's hibernation and hybrid sleep – especially if you're using an Ubuntu-based distribution such as Ubuntu Desktop, Kubuntu, TUXEDO OS, KDE Neon, etc. In this article we'll see what hibernation and hybrid sleep are, their caveats, and how to enable them on Linux with special instructions for Ubuntu-based distros. My test machine is a TUXEDO InfinityBook Pro 14" Gen 7, a rebranded Clevo laptop I purchased a couple of years ago. Without further ado, let's dive into it.

2. RTFM for Joomla and WordPress developers

   PHP, Joomla!, and WordPress keep changing. You're locked in a constant uphill battle to react to those changed. It's painful, and draining. There's a better way. You just need to… RTFM!

3. The grass isn't greener on the other side

   You're so frustrated with Joomla and having to rebuild your Joomla 3 site that you've made up your mind: you're going to WordPress! Been there, done that, got the t-shirt 👕

4. A simple question, isn't

   Today I got sidetracked by an article trying to answer a simple Joomla! question, and the incredibly wrong direction it took the answer to. I ended up writing the not-so-straightforward code to answer the question correctly, and had a lot of reflection on how changing, or omitting, the context of a question can be problematic.

5. The Joomla 4.2.8 security fix and why it's NOT the end of the world

   On Thursday, Friday 16th at 16:00 UTC Joomla released version 4.2.8 with a major security fix. The vulnerability, they warned, was a very serious one and you would all need to update. However, the necessary information gap which follows a security release —so as not to tip off miscreants— has let rumours spread in such a way that they make people risk unnecessary damage to their site, or at least give the false impression that all Joomla sites have been “magically” hacked like we're in some Hollywood movie. That's not how the world works, so please let us explain exactly what is going on and you should not freak out.
