I have a very simple anti-bot spam technique that works extremely well. It requires no javascript, cookies or complicated server weirdness, is fully accessible, has no hidden fields, has negligible overhead and takes just a moment or two to implement.

Most programming languages would prefer to use 0.5 as opposed to 1/2 because the later conflicts with the syntax of the languages. In this article, I will discuss an approach to working with fractions in PHP and CSS in one of the projects that I have done.

Online calendars are often used in many web applications. Though popular, the logic behind creating a calendar can be scary especially for those who are new to programming. There are many web calendars in the market but some of them are quite complicated. If we are not able to understand the code, it becomes harder for us to customise the calendar to fit into our existing application. As such, we need to create a calendar that can plug itself into any system seamlessly without problems. Whether we are using wordpress, mambo or drupal, we should only need to insert one line into our code for the calendar to work.
