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 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.

Domain Name Protection, Email Marketing, and IP Addressing



Steps to avoid having email domains blocked:

  2.  Refrain from sending large images, attachments or creating messages that are composed solely of an image(s).
  3.  When employing tracking pixels (Web bugs or beacons), clearly state their presence in your public privacy or P3P policies.
  4.  Practice due diligence by being aware of the age of your email lists and refraining from sending to inactive accounts.

Google killing app format used only by The 1% • The Register

This one is sort of a yawner as hardly anyone knew about or used this service in the first place.

But, anyway, yeah, they are ending the so-called "Chrome Packaged App"

China's futuristic 'straddling bus' is actually a thing

They built it. They actually built it.
After years of waiting, what was once a crazy dream has apparently become reality as China's infamous "straddling bus" went on its inaugural test run in Qinhuangdao, Hebei province earlier today.
