Why Linux is better then Windows: whoami

From this post I'm going to start a new series of posts in my blog. My intention is to spot some of non-obvios similarities and differences in this two OS. From a Linux user perspective of course.

Recently I've noticed that starting from Windows 7 this OS got the 'whoami' command which was taken from UNIX/Linux after about 20 or 30 years.

Not to mention 'Run as' option in Windows XP which was obviosly taken from the UNIX/Linux sudo example. At least a decade or two later I think.

Why Linux is ahead of Windows

It is known, that Windows 8 will get support for a new security feature called Intel SMEP. I'll omit the description what's that for because more important is Linux has had this feature since spring of the last year! And that is not all of it! Today one more technology that is to debut in next year's Intel Haswell line of processors got it's way into Linux kernel. Supervisor Mode Access Prevention.
