Thymeleaf: create page templates for web and non-web environments

12/02/2013 1 comment

Most likely you have found yourself in the following situation: you’re at the start of new web application project and one thing you need to take care of is the layout. Problem is that you can build static HTML templates with dummy data, but then you have to (manually) convert these into JSP. When you don’t have a running system you don’t have any choice but to make static HTML, or model templates a different way. Because of this the main problem will be on how to update the system given this (updated) design. This post will described the Thymeleaf framework which addresses these issues and will allow static templates to run unchanged in a web application.

Debugging web pages on mobile devices

As a web developer I often use front-end debugging tools like Firebug (Firefox) or Webkit Inpector (Chrome) to inspect or edit html & css and to run JavaScript (for example JQuery). Regular web pages shown by the browser can be inspected using such tooling as soon as the page is loaded.
With mobile devices however this principle is not (directly) possible. Of course you can run debug tooling opening the html as a file on your pc, deploy the application to a mobile device keeping your fingers crossed hoping it will run ok. It will be frustrating to see that web pages show and act different on a mobile device compared to the content being shown in a web browser on a pc. In this case the device is a black box and most of the times you have no clue what is causing the layout and behavior problem.
Searching the internet I have found a way to actually debug web pages on the mobile device using the browser of the pc. This article will show you on how to set this up, so that you can debug mobile web apps.

Is MongoDB a good alternative to RDBMs databases (like Oracle and Mysql)?

25/11/2011 1 comment

During the 10th Devoxx at Antwerp a presentation was given about MongoDB by Brendan McAdams from 10Gen.
This was one of the presentations during this event which I attended. I have to say I was pleasantly surprised by the ease of use and the features of this product. MongoDB is a NoSQL (non-relational, next-generation operational datastore and databases) database which is a schema-less database having huge advantages over most current existing RDBM databases.

The main pros of MongoDB can be divided in the following three:

  • Flexibility
  • Performance
  • Scalability

The aim of this article is to give an idea of this product, by giving an overview of advantages and disadvantages. Next, I will give some pointers to take into consideration in order to determine if this type of database is suitable for a specific situation or not. At the end of this article I will provide the link to the presentation that was given, providing more details (like example models & queries). Read more…
