Ultra-low-power transistors could function for years without a battery

Abstract of Subthreshold Schottky-barrier thin-film transistors with ultralow power and high intrinsic gain

“If we were to draw energy from a typical AA battery based on this design, it would last for a billion years." --- Sungsik Lee, PhD, in the journal Science

What's the best Technology Stack?

WE ARE bombarded daily with an endless flow of "cool stuff" that no web developer or programmer could even use in a lifetime.  So, what is the best technology stack to go with these days? 

Server? Classic virtualized Linux? A "cloud app" server? Heroku? AWS? Azure?Database? Use Hadoop clusters? MySQL? Redis? NoSQL? Relational?Primary programming stack? PHP/jscript? RoR? Python? Java?

Use any frameworks for the API or build from scratch? Phalcon? Django? Node.js?Frontend framework? ext.js? Angularjs? ionic? None/Bootstrap? 

If building a an app TODAY, what would you use and why?

How to recover the root password on Redhat Fedora and CentOS - My How To Articles

How to reset the root password:

1. Reboot the system.

2. When the boot loader menu appears use the arrow keys to select the distribution install you want to edit. Next press "A".

3. You will be given a grub prompt that looks like the following.

grub append> ro root=LABEL=/

4. Put the word "single" at the end of the grub append prompt and press enter. Note there is a space before the word single.

grub append> ro root=LABEL=/ single

5. The system will boot into single-user mode. At the prompt enter passwd root and enter the new root password.

sh-2.05# passwd root

6. Now reboot the server and you should be able to log back in as root.

What are kilobytes, megabytes, and gigabytes?

byte (B)
kilobyte (KB) - 1000^1
megabyte (MB) - 1000^2
gigabyte (GB) - 1000^3
terabyte (TB) - 1000^4
petabyte (PB) - 1000^5
exabyte (EB) - 1000^6
zettabyte (ZB) - 1000^7
yottabyte (YB) - 1000^8

it is estimated that all the printed material in the world only takes up about five exabytes.
