If like me you are using Django StaticGenerator to speed up your blog you should have noticed that your comments won't work anymore, since StaticGenerator will cache also the fields used by the django comment app to block spam and CSRF attacks.

In this post I'll share with you a quick and easy solution with jQuery.

Html purifier is a Joomla plugin based on the HTML Purifier library.

I developed the plugin in late 2007 with Matteo Maria Baccano, another PHP programmer I was working with at that time and now I just updated the plugin after a long time.

If you use Django you will surely know that its url routing is quite strict regarding the prettiness of its URLS but there are still cases in we need to handle query string parameters, like when dealing with external services that return a URL like: callback?verification_code=088145235648fs689sa56h&userid=854 .

Immagine that you need to add the possibility to upload a PDF or Zip file in the django admin, but you want to be sure your client will upload only these two filetypes and not other ones.

In this short post I'll share with you my simple solution.

While developing this web-site I encountered one of those little tipical annoying bugs that characterize Internet Explorer. Even if version 8 is a much better browser than versions 6 and 7, it still sucks under many points of view if compared to other modern browsers like Firefox, Safari, Chrome and Opera.

The issue I want to talk about in this post is the use of a repeated 1x1 pixel semi-transparent background. While this works just fine in all the other modern browsers, IE8 has a little issue that drove me mad.

It never took me so much time to build a web-site in my life.

I started to work on this web-site in the summer of 2008 but unfortunately, due to high amount of work and personal problems I've never had time to finish it. Recently I finally had the chance to finish it but unfortunately I didn't like the original design anymore, so I redesigned it again. 

Now I am almost close to launch it and I am very satisfied.
