One of the things that annoyed me about using Fedora 11 is the way the default filesystem browser behaved whenever you decided to enter a folder – it would automatically open a new file browser window.
	This WILT shows you how to make Nautilus open the folder in the same window rather than spawning a new window.
	
		- Open a new Nautilus window by double clicking on any folder on your Desktop, or by clicking through Places -> Home Folder.
 
		- Select Edit -> Preferences.
 
		- Under the Behavior tab, enable the Always open in browser windows checkbox.
 
	
	That’s it. I blame it on a poorly labelled toggle that sounds more like Nautilus is going to open files in my web browser.
 
	When attempting to perform certain operations using the sudo command on my Fedora installation, I receive the error message saying
    isaac is not in the sudoers file. This incident will be reported.
	Here’s how you can fix it.
	
		- Log into the root account.
#su
  
		- Once in the root account, edit the 
sudoers file.
$pico /etc/sudoers
  
		- Look for the line that looks something like 
root  ALL=(ALL) ALL
  
		- Underneath that line, add your username (in my case, isaac).
isaac  ALL=(ALL) ALL
  
		- Ultimately, your 
sudoers file should look something like this 
	
       root    ALL=(ALL) ALL
       isaac   ALL=(ALL) ALL
	Note: The sudoers file is a security measure that prevents normal users from executing commands that may harm the system. Use this with great caution.
 
	I tried to set up a simple DHCP server on my brand new Fedora 11 installation via Webmin. I’d put in all the relevant information, but I kept getting a dhcpd start fail.
	When I tried starting the dhcpd
      $ sudo /usr/sbin/dhcpd
	it returned an error that looks something like:
      No subnet declaration for eth0
      ** Ignoring requests for eth0
	What I found out is that webmin looks for the dhcpd.conf file in /etc/dhcpd.conf while Fedora 11 places it in /etc/dhcp/dhcpd.conf.
	To fix this:
	
		- In webmin, click on the Module Config link on the top left corner of the DHCP Server webmin page.
 
		- In the DHCP server config file text box, change the value to /etc/dhcp/dhcpd.conf then save.
 
		- Reconfigure the DHCP Server configuration.
 
		- Click ‘Start Server’ when you’re done.
 
	
	It should work now.

	Blackberry makes really good devices for phone calls and SMS’s, but I haven’t found a good enough reason to shell out almost $30/month for the privilege of using their email service. 
	Till now, the only browser I get to use is Opera Mini, which is quite slow and heavy compared to the native blackberry browser.
	Recently, I’ve found a way to reenable my blackberry browser by installing some custom services books. These service books configures the browser to use a standard TCP/GPRS connection rather than the BIS/BES connection.
	This also means no more ‘Unable to open a PDP Context’ and ‘blackberry.wap’ errors.
 
	After ensuring that the folder actually exists and the permissions are set right, try looking up the php_safe value.
	Sometimes this error comes up because the php_safe value is turned on.
	Either turn it off yourself, or try and get your web hosting service to turn it off for you.
