What are the programming languages that were used to develop the Plan9?
Probably the Riga Technical University and University of Latvia continue teaching coding in binary code, ie, machine language. I say this because about three years ago the Riga Technical University and University of Latvia continued teaching coding in binary code, ie, machine language. The Riga Technical University and University of Latvia made based projects in Plan9 using coding in binary code? The developers of Plan9 think there was no point in coding in binary code three years ago as they did or make the Riga Technical University and University of Latvia?
