I have been doing a little housekeeping on the site. There are a few changes that I think are worth mentioning. They are all related to some new content that you can access on the top of the webpage.
You have fast and easy access to a lot of very interesting links if you click on very useful as well as on Direcciones Interesantes related to search engines, web 2.0, GNU/Linux, free software, etc. Let me be clear, these resources are done for my students for academic purposes but I think it is very useful to have them freely available for everyone at anytime.
Please, let me know what you think about that, how you would improve it, etc. Your comments encourage me 
and help me to keep going. 
This post is realised by my pupils Kristian Orre, Miguel Muñoz Sánchez and Adam El Azrak Centeno. I hope you may enjoy it. It’s a collection of movies about free software and GNU/Linux.

I would like to talk about conceptual maps. I think it’s a wonderful tool to learn new ideas, concepts, facts, etc, as well as a extraordinary way to express yourself very plainly and visually. Conceptual maps help us to represent the concept and focus on the relationships between the main concepts and ideas rather than losing yourself in the details. No wonder they are used in so many areas, contexts and circumstances, they are used in schools, universities, business, corporations and organizations as useful tools for discussing, sharing and collaborating.

The Internet is evolving very fast. It is also changing the way that we think about computers and operating systems. It used to be that all the attention was focused in a powerful personal computer and a good operating system full of applications – not any more!
As time goes by, I find more and more web services that are free (or rather let’s say “no costs” that is more accurate), simple, multi-platform (you just need a web browser and you can get access on a PC, mobile device, e-book reader, etc.) and they are also very useful and easy to share with friends or partners 
. This post is about operating systems in the cloud. I covered eyeOs a few months ago but there are many alternatives out there that are worth mentioning. View Full Article »
There are many utilities in Ubuntu related to many purposes. Let me introduce you to some which are useful and interesting.
An ebook reader is a device which allows you to read ebooks. There are many types of ebook readers, but I will refer to those which have an electronic ink display. In other words, you have the same experience as with a real book. They are easy on your eyes and the environment because we don’t need to chop down any trees to have accessible books and information 
However, there are three main problems:
- There are a lack of choices and expensive ebook readers (Kindle DX, iRex Digital Reader, Sony, etc.).
- People are not as used to reading books as they used to be.
- And finally, it’s hard to find ebooks.
The first of these problems requires time, the second needs a different attitude about the importance of knowledge and education. As far as the last problem is concerned, I will show you some places where you can get free ebooks. View Full Article »
