Programming a mobile app for different platforms can be now much easier with Apache Cordova. The reason is simple. Cordova is an open-source mobile development framework for developing mobile apps in more than one platform.

Twitter is a wonderful service, but, until now, you have to subscribe to some websites to be alerted when a selected word (maybe your trademark) is tweeted. We’ll try to develop a service that filters the tweeter api, stores the interesting ones in our database, and show them in the browser in real time. If […]

Writing CSS is good fun, but analyzing an html document to find how the page is structured us, at the very least, tiring. If you have ever had to write CSS for a blog or CMS template, you already know how time-consuming is to find every ID and CLASS in a large document. We’re going […]

But there is a technique that can imitate it until certain point. You can find where your users are clicking using just a bit of javascript and server side programming. Find out how…
