Mounting my Coby Kyros MID1045 Tablet in my Ubuntu Precise

Hi, well this is the first step in the journey of root the Coby Kyros MID1045 tablet, so I was reading how to mount it in Ubuntu and many webpages mentioned that most of android devices use the MTP filesystem, so I needed to install it, here it is the lines:

sudo add-apt-repository ppa:webupd8team/unstable
sudo apt-get update
sudo apt-get install mtpfs mtp-tools

then you need to create a directory under /media and type this line in terminal:

sudo mtpfs -o allow_other /media/AndroidDeviceDirectoryYouWant

then, in theory you just need to plug your USB cable to your laptop or PC, and then type this:

mtp-detect

But, oopss!!!, I got this:

Listing raw device(s)
   No raw devices found.

So, what happened??? I checked the screen in my tablet and I saw an icon like Android+USB, I tapped it and I found that this tablet in particular still use the USB storage as the method to connect to any PC, weird? why? yeah, it is, and I think the weirdest part that I have to say is just before install mtpfs I did not get this icon. Anyway, once I tapped it I can mount it and read the content from ubuntu.

If you have any other android device you should use the method of mtp to connect it to your ubuntu box.

I really newbie in this Android Field, if you have feedback of any kind, feel free to post it/comment/reply this; in fact I read about this tablet and it's weird, in fact it is not Google Play Ready, so I'll go for unlock this

Bye

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.

1. install it: apt-get install cpufrequtils

2. try it like this: cpufreq-info | grep 'current CPU'
