Whether working on a server or a low end machine, you don’t want to bog things down even more by running a GUI — plus you need to know how to use the power of Linux and the GUI is just not it.
It is possible to accomplish most any task while working from within the shell. Having the knowledge of what and how to use the applications that are available is the key to being a successful CLI expert.
The following is a guide for the command line applications needed to work freely from within the Linux terminal. Now get off of your GUI butt, get typing, and throw your mouse in the trash.
NOTE: Most of the applications listed should be available from the distribution’s repositories. Options and configurations of applications listed are not covered in detail. man [cmd] should be used to explore options not explained here.

Will Computers ever reach a state that they will be able to develop and improve themselves? Eliezer S. Yudkowsky thinks it will be as soon as 2021 by the terms of Moore’s Law.

The short version of the paper:
If computing speeds double every two years,
what happens when computer-based AIs are doing the research?
Computing speed doubles every two years.
Computing speed doubles every two years of work.
Computing speed doubles every two subjective years of work.
Two years after Artificial Intelligences reach human equivalence, their speed doubles. One year later, their speed doubles again.
Six months – three months – 1.5 months … Singularity.
Plug in the numbers for current computing speeds, the current doubling time, and an estimate for the raw processing power of the human brain, and the numbers match in: 2021.
But personally, I’d like to do it sooner.
I think the question is not if the computers can think in the same speeds as we do, but if we can program computers to ‘think’ anything like the dynamic power of the human mind. This will be much bigger task than producing yottahertz.
