Muchos ya sabemos escribir algunas líneas de código y también sabemos lo fácil y rápido que se pueden escribir scripts sencillos en python. Si quieres dar un paso más y no sólo saber tirar líneas de código, sino además saber como se mueven los datos por la memoria, los objetos que se crean, sus punteros, etc. entonces Online Python Tutor es para ti. Es una herramienta genial, online y gratuita en la que puedes escribir, probar y depurar tus programas. Además, lo que más me ha gustado de la misma, es que puedes ver de forma gráfica los objetos y marcos de memoria (frames) que va creando tu programa. Es ideal sobre todo para depurar tus programas.

La nebulosa se llama IC1396 y está a 2000 años luz de distancia, en la constelación de Cefeo. El fotógrafo es JP Metsävainio y realiza un supuesto 3D intercalando fotografías y realizando cálculos de movimientos con las estrellas principales, la brillante de arriba es mu Cephei, una gigante roja supermasiva. Sus gases son azules en el interior (Oxígeno) y rojos en el exterior (Hidrógeno) estas coloraciones indican también que tipos de estrellas coexisten en la nebulosa ya que algunas ionizan los gases y modifican su color.

Creación de una "cueva" usando un algoritmo explicado en el artículo llamado: The Cellular Automaton Method for Cave Generation

Math ∩ Programming

En él puedes encontrar artículos donde explican primero conceptos y algoritmos matemáticos y luego  su respectiva implementación en un lenguaje de programación.

Pero el que más me ha gustado es: The Cellular Automaton Method for Cave Generation. En él se explica cómo realizar cuevas para mazmorras de juegos de aventuras usando autómatas celulares. Genial.

Dos imágenes valen más que mil palabras ;)

Para aquellos que pasamos muchas horas delante del ordenador y del teléfono móvil, nunca viene mal recordar estos consejos para no dejarnos la vista ni el cuello.
