Caixa Mágica

Since I'm a fan of Debian, I could not test the new version of the Magic Box (CM16) based on this operating system (OS). There are about 2 months installed it on my desktop PC today and installed it on my laptop.
First impressions is that I have a full OS with office tool LibreOffice 3.3, EXT4 file system, Firefox 4.0, Shotwell Photo Manager, Banshee Music Player and automatic detection of proprietary drivers.
For instant messaging (IM) is built Empathy surprised me this new version the interface simple and friendly and the ability to connect to multiple IM systems. With Gwibber diffusion can add accounts like Twitter, Facebook and identi.ca, providing a common tool to interact with these social networks.
The Magic Box Software Center is very well played as a tool for package management. It is organized by categories and still have a dynamic part of recommendations.

What can I say more?! Try it and you will see will like it.

Video Editing on Linux - See OpenShot Editor

Just recently I needed to edit videos and I'm a layman in this field had some difficulties.Among various tools I tried, the simplest and quickest way to learn was the OpenShot.
The installation of this tool for Debian distributions can be done through Synaptic it is in the repositories. If you prefer to install "a la pata" is as follows: sudo apt-get installOpenShot.
The features available are not many, but for many users (like me) arrives perfectly.


features:
Cut pieces of the video;
Add tags in the video;
Multiple bands;
effects;
transitions;
Import video, images and sounds;
Undo changes;
Export to various video formats;

How to put a video on a track:
(1) Click on the icon + (plus) and choose the video;
(2) Move the video imported onto the track at the outset;
(3) can add other video, pictures and even music files / sounds;

How to cut pieces of video:
(1) pick-and functionality divide and clicking with the mouse at the beginning and end of the piece to remove;
(2) Clicking the right mouse button over the video piece and remove;

Add a picture:
(1) Click on the icon + (plus) and choose the image;
(2) Move the image to the track where if you want to place;

Add effects and transitions:
(1) Just select the transition and move up the track to the site, where you want the transition;
(2) In effect, it is the same thing, but this is all in the band, or piece of track if it is divided;



Export:
Although you can export to many different formats, I will present the simplest and Iworked flawlessly.
(1) File -> Export Video -> Tab: Simple -> Profile: DVD -> Destination: DVD-NTSC ->Video Profile: DV-NTSC -> Quality: High -> Export.

Linux - Screen Resolution in Portable 10 "

Today I had a problem installing Red Hat Enterprise Linux 16 (CM16) with a portable screen 10 "because the operating system can not detect the resolution and that it should use. The image was so poor he could not even read the text presented.

To overcome the problem follow these steps:

     I called a TFT monitor to the laptop and carried out the installation as usual;
     Once installed the CM16, I had to make the resolution setting the screen, manually in xorg.conf file:
         vi / etc/X11/xorg.conf (if no, it is created);
          Paste the following information:

                  Section "Device"

                  Identifier "Video Device Configured"

                  Driver "OpenChrome"

                  option "PanelSize" "1024x600"

                  option "ForcePanel"

                  EndSection


         Restart.

This problem happened to me on a laptop (type NetPC) brand Elonex Webbook. This solution resulted in CM16, but probably also work on Debian based distros (Ubuntu, etc).

To resolve, in my case resulted, can eliminate the Dropbox folder settings in your user,which should be / home /% user% /. dropbox.

Configure a network interface with ifconfig

May eventually need to configure a network interface in a very quick but not permanently.To do so can use the ifconfig command as follows:

ifconfig eth0 192.168.10.200 netmask 255.255.255.0

If you do not know what is the interface or if you want to check if the configuration iscorrect, they can simply run ifconfig.

After configuring the IP is to configure the gateway (gateway). In this case we will do isadd a route to route network packets to the gateway:

route add default gw 192.168.10.254
