Many people are unaware of fact that there are many freeware and open source tools and applications out there on internet which they can use for their day to day work without shelling out extra bucks.

Microsoft has introduced a new feature in Internet Explorer 8 called “Accelerators”. These accelerators help you quickly perform your everyday browsing tasks without navigating to other websites to get things done. Simply highlight text from any webpage, and then click on the blue Accelerator icon that appears above your selection to perform the respective task.

1
$ write username tty

Everyone knows that CPU utiization in windows can be found out from Windows Task Manager. But what about Linux? Well Linux has also got set of utilities to monitor CPU utilization. With these commands you can find out total CPU utilization, individual CPU utilization (for SMP machines), your system’s average CPU utilization since the last reboot, determine which process is eating up your CPU(s) etc.
