Firefox: Search in the address bar

On some Linux distributions engine that comes by default may not be your favorite.
In my case I'm currently using Linux Mint comes DuckDuckGo! Therefore need to be questioned! that crappy search engine! Damn I do not know, but polls are by far the ones I would expect!

The worst is that I'm so attached to search through the address bar, I had to go to the fight! : P

They get to know that can change this default engine, putting in the address bar this: about: config -> confirm that it wants to move forward -> search for "keyword.URL" -> give 2 clicks -> put the text box " =" (without quotes). And thus stay with your favorite engine. In this example I used Google, but could be any other.

In practice, when you reconnect the monitor cable from the graphic does not come back, showing a screen in text mode, forcing the user to restart the computer to overcome the problem.  
Possible solution: 
If there is no xorg.conf file, run the command X-configure. This command will create the home user who is sitting in a model of the xorg.conf file. Then move that file to the right place, which should be in / etc/X11/xorg.conf (may vary with the distro used).

Configure network interface on FreeBSD

My contact with FreeBSD has been little, but today, I needed to configure a network interface with static IP address. The best I got was to do:  
  1. Run the command sysinstall 
  2. Go to configure -> Networking -> Interfaces 
  3. Select the interface (example le0). 
  4. Configure the network parameters: Name, Domain, IP Mask, Gateway and DNS.  
  5. Finally it is recorded and exits from the configuration tool.  
By now the setup should be working, if you still can not ping any host on the network and gives you the message "Permission denied" in all likelihood have the firewall active. You can stop the firewall with the command ipfw disable firewall.

In times of crisis, Linux may be the choice!

According to this news digital diary (DD), the "Linux advances on Windows andUnix in the Enterprise '! Needless to say that I read this news with great satisfaction. As the crisis global installed, there are already many administrators who intend to migrate servers to free platforms, says the second study that formed the basis of news dd. I hope you do not remain the intention! In Portugal, despite the crisis hit, I think this market (open source) will not grow, because mostmanagement applications (billing, accounting, etc.) work on Microsoft platforms(client and server) and not simply its migration to Linux based systems. One day,perhaps, this paradigm shift, that is, the technology is all over the market! Have you thought about buying a computer solution for your company and only pay for the hardware, service and little more? Well no! And antivirus? You do not need!And antispyware? You do not need! And format the PC and need to insert a dateserial numbers that the client already lost? You do not need! And being forced tobuy the new new version of Windows and Office M. to keep up? You do not need!Of course, the Windows operating system also has its advantages, but when the discussion is cost containment, there is not much to say.
