Features of a desired system environment

Wow, these features are really cool, they are taken from the Data Warehousing book that I'm reading that I wrote in a previous post, so here they are:

  1. Database designed for analytical tasks
  2. Data from multiple applications
  3. Easy to use and conductive to long interactive session by users 
  4. Read-intensive data usage
  5. Direct interaction with the system by the users without IT assistance
  6. Content updated periodically and stable
  7. Content to include current and historical data
  8. Ability for users to run queries and get results online
  9. Ability for users to initiate reports
So guys never forget those one, in IT environment these kind of features are so helpful.

deactivate bluetooth service from terminal

At this date, chrubuntu is still in alpha stage, the community around it is still in development process, so last night I did some changes on it now this morning I can't deactivate my bluetooth service from graphical mode, so, let's do this from terminal.

1. first let see if it's running:
  service bluetooth status

I got something like this:
bluetooth start/running, process 341


2. now let's stop that process:
sudo service bluetooth stop

if you check it again  the process has been stopped.

and that's it

five principles of strategic information

Hey this is an interesting post, I'm reading a book called "Data Warehousing Fundamentals for IT Professionals 2nd Ed" from Paulraj Ponniah, I'm in the first part but I have found great topics, and I want to share one of them, the five principles of strategic information are:

-Integrated: must have a single, enterprise-wide view.
-Data integrity: information must be accurate and most conform to business rules.
-Accessible: easily accessible with intuitive access paths, and responsive analysis.
-Credible: every business factor must have one and only one value.
-Timely: information must be available within the stipulated time frame.

I know a couple of companies that should follow those characteristics, specially in the management of the information, but anyway.  Mr. Ponniah gave a hit write those characteristics, he's absolutely right, I'm exciting reading this book, it was a good decission.

Cheers

installing python in a debian based distro

So, for different reasons I need to install python in my chrubuntu, googling I found that several users have extremely different opinions related to the installation process, I think that the main reason is the OS, in some GNU/Linux I found that it would be a messy process but in others, specially the debian based, it's easier, so here they are the steps that I followed:

sudo apt-get install python-software-properties
sudo apt-add-repository ppa:brightbox/ruby-ng
sudo apt-get update
sudo apt-get install build-essential ruby rubygems ruby-switch
sudo apt-get install ruby1.9.1
sudo ruby-switch --set ruby1.9.1
sudo ruby-switch --set ruby1.8

as you can see, it's very simple, in fact, I don't have much to say because these are my first steps with ruby, I found a lot controversy in the versions, 1.8 and 1.9, but you know, in future posts I could have useful comments or info, specially related to IDE's.
