Optimised authentication methods for Ubuntu Desktop

Still counting on passwords to protect your workstation? When set up properly, alternatives to passwords provide a streamlined user experience while significantly improving security. These alternative authentication methods can also easily be combined to create a custom and adaptive authentication profile. This whitepaper introduces three popular authentication methods that provide a solid alternative to passwords. Perhaps you’d like to configure your laptop for login using a YubiKey hardware token connected to a dock. Another option could be to login with a Duo push notification when not connected to the dock, but use a Google Authenticator one-time password when no network is available. Maybe you need a separate hardware token just for ssh authentication, and you always need to keep a long, complex password for emergency authentication should all other methods fail. All of these scenarios can be easily configured within Ubuntu.

Open Hardware: Arduino, RISC-V and 96Boards

• Arduino-controlled robot arm is ready to play you in a game of chess

  If you’re tired of playing chess on a screen, then perhaps you could create a robotic opponent like Instructables user Michalsky. The augmented board runs micro-Max source code, enabling chess logic to be executed on an Arduino Mega with room for control functions for a 6DOF robotic arm. The setup uses magnetic pieces, allowing it to pick up human moves via an array of 64 reed switches underneath, along with a couple shift registers. The Mega powers the robot arm accordingly, lifting the appropriate piece and placing it on the correct square.
