Nicholas is a Mechanical Engineer turned web developer. He found Mambo — Joomla's precursor — in 2004 and his life was never the same.

He's the author of several popular extensions for Joomla and a frequent contributor to the Joomla core. He currently lives in the coast of Athens, Greece with his wife, daughter and two cats. He likes to credit the Joomla community for giving him a business and a family — he met his wife at a Joomla conference, after all!

When he's not writing code, documentation or articles for Joomla and his extensions he enjoys tinkering with mechanical keyboards, playing D&D and watching sci-fi series.

Joomla Performance Tuning III: Static Media Optimization

January-J4Performance

In the second part of this series I described how to unlock a base level of performance out of your Joomla site with a few, simple changes. Today we're diving deeper into static media: JavaScript, CSS and image files. These changes are more involved but can turn a junker of a slow site into a decently performing one. Arguably, not all of these changes make sense for all sites but the performance benefits you get are substantial.

Joomla! Bug Sprint in Manchester

Joomla! Bug Sprint in Manchester

On the weekend of July 26th and 27th nine developers from around the world gathered in Manchester, UK to clean up Joomla's bug tracker. The project's bug tracker had grown unkempt, with hundreds of issues that were stagnant for a long time. Some issues were there for over a year. Moreover, the JoomlaCode issue tracker wasn’t really fit for the amount of growth Joomla had experienced since 2005. It was necessary to put the number of issues under control and move to an improved bug tracker and that was the goal of the Joomla! Bug Sprint.

How off-line is Joomla!'s off-line mode?

How off-line is Joomla!'s off-line mode?

Joomla!’s temporary off-line mode is a very handy option to temporarily take your site down while performing maintenance —e.g. updating the Joomla! core or an extension— and is even suggested by the official documentation for the unfortunate time that your site has been compromised. However, is this really off-line, or are there any pitfalls you should be aware of?

Team EaSE Article: eCommerce - Will they pay...

Team EaSE Article: eCommerce - Will they pay...

With the abundance of e-commerce solutions for Joomla! it is very easy building a great looking on-line store, showcasing your products and effectively convincing your potential customers to add them to the cart. Beautiful images, obvious calls for action, unique selling points and a smooth online shopping experience are easy to setup and help you “seal the deal” with the customer. However, this is only half the story. One of the most overlooked business decisions when building any kind of e-commerce site is the payment method. It’s what affects the very last step of the online shopping experience and the single most frequent reason to lose a sale.

Only a Ninja can kill another Ninja

Only a Ninja can kill another Ninja

If you were to provide a short list of the threats against your site, which one would be the number one threat? For me, it's script kiddies. Those pesky individuals who don't have a programming bone inside them, but still can cause a great deal of harm to our sites by using pre-packaged attacks against them. Their success rate is amazingly high, mostly due to our fault. The purpose of this article is to demonstrate some trivial techniques to add a degree of stealth on your site so that script kiddies can't launch their attacks and even if they do, they will most likely be fended off successfully. Just like a ninja, you'll learn how to have your site lurk in plain sight without being spotted by those pesky attackers.

The Joomla! Developer's Bible

The Joomla! Developer's Bible

On quite a few occasions fellow developers ask me which is the best way to get started with Joomla! Development. Among other things, I always propose that they should have a complete reference of the Joomla! Framework API. The only book which was up to this task was "Mastering Joomla! 1.5 Extension and Framework Development", albeit a bit outdated since it was written when Joomla!1.5 was still in beta, some two and a half years ago. When Packt Publishing announced that they'd release the updated "Mastering Joomla! 1.5 Extension and Framework Development (Update)" I was ecstatic! So, here you go, I reviewed the new edition of the book and I'm willing to share my experience with you.
