There was such a long time since I haven’t updated my blog. The reason is that I’ve been really busy with other projects. However, pretty soon I am starting to teach a very interesting course based on developing websites on the J2EE platform using the Framework SpringMVC 4, Maven 2 and Hibernate 4.x , trying […]
During the last years there was such a strong movement toward encouraging developers to test their apps. These tests were usually unit tests. However despite being an essential part of the development of every single application, does not seem to be enough to assure that it is free of bugs (yes, I know any amount […]
One of the main things that are key to keep the user experience on your website as higher as possible is the amount of time that your server takes to sent pages to the clients. There’re a number of good practices that can be done to keep this waiting time low. You can find on […]
When you’re dealing with files and your website makes it possible to users to upload photos, videos or any other kind of files, it can be useful to store them up in the Cloud instead of in your current Server Distributed File System. This is a good choice especially when you don’t own the specific […]

During this Christmas break I’m trying to improve the PHP contents I usually teach. I tend to structure the course in a way which gives me time enough to explain how an MVC Framework works and, for that purpose, last year I chose Symfony due to it’s one of the most widely used by companies […]
Web workers are a technology which allows us to delegate tasks in background using client-side programming. Until now with pure Javascript it was not possible to start or run multiple tasks at the same time. Web workers provide an easy way to split tasks in different contexts. How this works is rather simple. From your […]
When developing an application, traditionally we were used to mix HTML code with Javascript (jQuery) to render the data coming from an Ajax call. However the result of doing this is a bunch of code which is not very readable and maintainable. To try to overcome this situation several frameworks have come up. They’re the […]
So now a very good practice would be to go back to the first dummy app (MDPA4W) and do just a bit of refactoring. Basically, I’ll locate the statement of the Sleep method inside another one which signature is called takeARest. Then I’ll instantiate a thread that takes advantage of that, and just run it. […]
