Un porcentaje de los alumnos que estudian programación en distintas partes del mundo no logran aprender a programar. La curva de los resultados en los exámenes se parece a dos curvas normales superpuestas, las dos jorobas. Este paper describe un test simple que permite saber si alguien va a poder programar o no.
"Otherwise you're reinventing the wheel for no benefit whatsoever."
Closed source is equivalent to reinventing the wheel over and over again. But who said reinventing the wheel is bad?
When the wheel was first invented it was made of wood/stone and was probably the size of an ox cart wheel.
Imagine if the wheel is never reinvented and has remained the same till today... Imagine...
1. A bicycle using big ox cart wheels. 2. A car being driven on ox cart wheels. 3. A formula one car racing on ox cart wheels. 4. A bus running on ox cart wheels. 5. A train running on ox cart wheels. 6. An aeroplane taking off on ox cart wheels.
Even a wheel is worth reinventing again and again. Closed source is worth money just because it keeps reinventing things and making them better.
