Sneak peak to OOP - Pagination class

I would like to begin with a statement that page navigation or pagination was planned to have its own post but since it was necessary for the gallery at the time, I have decided that there will still be a post dedicated to pagination. However, to avoid duplicate content, the plan is to rewrite it in object-oriented programming(OOP) style which brings a whole different paradigm and mindset to the table which again makes me wonder whether or not I want to have an...

In this tutorial, I'll be showing you how to make a safe to use, yet simple, gallery with thumbnails, without database, using PHP only.

What is a Regular Expression? (Regex)

Sooner or later, anyone using programming language or languages on a regular basis will come across regular expressions, either out of necessity or out of interest.

How to survive against online cracking tools?

Today, I want to talk about why one needs to be careful when it comes to the login application, why to avoid using outdated hashing methods when authenticating and how to protect against online dictionary and brute force attacks. But sometimes, it's better to look at it from different perspective to get a better picture. So for this discussion, I have designed a python tool that attacks login apps to get the password of the username provided. To help you understand...

What are CSS sprites and how to create them?

Update: Please note that the layout has recently been changed and that the side navigation on desktop no longer uses images but what is said in the following article still remains true. Basically, in one sentence, CSS sprites are images that contain more than one image together as a single file. While this may seem counter productive at first, to put images together in your favourite image manipulation toolkit, it is actually easier to do and more beneficial for your...
