Según la wikipedia:

Aprendizaje profundo (en inglés, deep learning) es un conjunto de algoritmos en aprendizaje automático (en inglés, machine learning) que intenta modelar abstracciones de alto nivel en datos usando arquitecturas compuestas de transformaciones no-lineales múltiples.

En deeplearningbook.org podemos encontrar un libro (en proceso de publicación por MIT press) sobre este subcampo de la inteligencia artificial. En dicha web podemos además encontrar enlaces a tutoriales sobre deep learning, y pronto también publicarán presentaciones usada por sus autores para la enseñanza de esta materia.

Es un libro orientado a estudiantes universitarios y aquellos profesionales que no tengan una base en machine learning y más específicamente en deep learning.

The Little Go Book es un proyecto que nació hace un par de años, el cual nos introduce al lenguaje de programación Go.

El libro en sí lo puedes bajar en varios formatos: PDF, epub o mobi. El proyecto está alojado en Github y hace un par meses que se creó en Github también, con una traducción al español del mismo. Este versión la puedes descargar en formato PDF o acceder al fichero markdown.

 

Aquellos afortunados que pudimos disfrutar del mejor ordenador personal entre mediados de los 80s y los 90s, sí, me refiero al Commodore Amiga ;), en algún momento se ha sentado a ver alguna demo gráfica, más conocida como demoscene,  de las que ya hemos hablado alguna vez.

Para mi, programar una de estas demos, es ir al límite, es programación en arte puro, es sacarle el máximo partido al hardware.

Después de que se publicara el material de DeepSec 2015, ahora también tenemos los vídeos disponibles:

Allá por 1979 se lanzó un juego para Atari llamado Star Raiders, un juego de 8 bits en forma de cartucho, que para la época fue muy innovador, por varias de las técnicas usadas.

Éste era un simulador espacial en 3D. Hacía uso de lo que llamaban player-missile graphics, esto era la “versión sprites” de Atari, hacía uso de cálculo de puntos 3D, la pantalla se dividía en partes con distintas funcionalidades, usaba gráficos de fondo, etc. Bastantes cosas que no parecen fuera de lo común, pero que para la época eran bastante impresionantes.

Una de las conferencias sobre seguridad referente a nivel mundial, Black Hat, ya ha publicado el material de la edición Asia 2016.

Personalmente creo firmemente en la educación continua y la lectura es uno de los pilares fundamentales de la  misma. De hecho, la lectura en general debería ser parte de nuestra vida.

Leer libros, artículos, blogs, etc es algo que me gusta bastante, pero algo a lo que le tengo amor-odio son lo textos académicos. He leído muchos que he disfrutado y otros que son muy aburridos, quizás porque están llenos de teoría y anotaciones matemáticas que me superan.

ltrace y strace son dos herramientas comunes en sistemas *NIX que son súper útiles a la hora de ver las llamadas a librerías y sistema de un proceso o aplicación. Muy útiles a la hora de depurar un proceso o hacer ingeniería inversa.

En estas dos entradas:

• How does strace work?
• How does ltrace work?

El autor nos explica el funcionamiento interno de ambas y las diferencias entre las mismas. Son entradas muy cortas, pero muy educativas.
