We love the little C.H.I.P. Single-board computer. And it boasts some really powerful specs for only US$9. Yes, only US$9.

These somewhat really minuscule computers are even more powerful than the original Raspberry Pi that came out five years ago.

CHIP and Pi Zero W offer an opportunity for hobbyists to build even cooler gadgets with really cheap computers as compared to high end raspberry Pis. CHIP offers some wonderful products, including PocketCHIP, which is a fully portable computer in your pocket. It comes standard with battery, screen and a working keyboard for around US$70.

Howto Login to servers using SSH keys authentication

Using public key authentication is far more secure and smart way to manage server authentication. And it is quite easy to implement and use. Fortunately, unix/linux terminals allow users to create public/private SSH keys combination that can be used to authenticate and login to servers without any hassle.

The traditional SSH authentication using the combination of username/password is good but really not that secure anymore. The passwords can be guessed or even broken using brute force attack. At times even a compromised terminal can give away the passwords to hackers.
