Mangocast #PictureChallenge

Para probar las capacidades “sin precedentes” de la cámara del flamante iPhone Xs Max, lo sometimos a un #PictureChallenge que consistió en tomar la misma foto con 5 teléfonos y calificarlas a ciegas, es decir sin conocer cuál foto había sido tomada de qué teléfono. Los teléfonos que compitieron fueron:

La única foto que se tomó con  las diferentes cámaras fue esta:

Vos también podés participar de este desafío entrando con tu cuenta de Google a este formulario. Ponele notas a las fotos, de manera que cada foto tenga una nota distinta: la mejor foto debe llevar 5 y la peor 1. 

Las fotos publicadas no tienen otro retoque que ajuste de rotación y tamaño para que todas luzcan lo más similares posible para minimizar el efecto de que otros detalles afecten tu criterio. Por si acaso, incluimos links a las fotos originales a las cuales lo único que se les hizo fue remover los metadatos para que no puedas inferir la cámara a partir de estos.

A propósito de metadatos, extrajimos los EXIF para que compares lo que decidió cada cámara al tomar las fotos (ofuscamos la información del GPS por razones obvias).

Episodio #91 – El silencio de los nerds

Con un clima otoñal, el panel del Mangocast se reunió con el entusiasmo de siempre, alentado por la llegada del episodio #100 que marcará un hito en la historia de este grupo.

La pregunta del día: ¿Qué herramientas que vos usás es para vos fundamental y otros no ven su utilidad? y ¿Qué herramienta que otros usan no parecen ser tener tan útiles para vos?  demostró  tener una profundidad no anticipada e incluso sus ramificaciones podrían ser exploradas con aún mayor detalle en el futuro.

Uno de los temas que tratamos es la forma de hacer un sistema informático capaz de soportar un ecosistema de plugins, al estilo WordPress (parecería que Pablo aprovechó el episodio para lograr una consultoría gratuita 😅).

Con el advenimiento en puerta del Samsung Galaxy S8, discutimos las características, bondades, beneficios y defectos e inconvenientes del teléfono insignia de la némesis en hardware móvil de Apple.

Finalmente recordamos los eventos de 1991, entre los cuales resaltan: la presentación en sociedad del WWW, el lanzamiento de Linux por Linus Torvalds, los inicios de Windows NT y su relación con VMS y el lanzamiento de Sistema-7 y la PowerBook por parte de Apple.
