Modern GNU/Linux systems offer graphical desktop environments both simple and sophisticated, but at the heart of the Unix tradition is a more fundamental abstraction: Text. We'll sketch out the origins of the command line, and set the stage for an exploration of its unique abilities.
Running OpenGL-based Games & Emulators on Adafruit PiTFT Displays
More Games = More Fun!
by Phillip Burgess
Adafruit’s PiTFT displays link to the Raspberry Pi’s GPIO header instead of a video port, making them compact & ideal for portable projects. But this connection normally limits them to a subset of specially-compiled games and emulators — high-performance OpenGL-based games were previously incompatible. New software now makes gaming more practical on these tiny displays!
Node.js Embedded Development on the Raspberry Pi
Get you a Pi & write you some javascript!
by Todd Treece
JavaScript was designed to handle user interaction in a web browser, but what if you could use it to power your hardware projects?
