For sure:  "War without reflection is mechanical slaughter,” said Christof Heyns, the United Nations special rapporteur on extrajudicial, summary or arbitrary executions.

“A decision to allow machines to be deployed to kill human beings worldwide, whatever weapons they use, deserves a collective pause,” he told the Human Rights Council in Geneva."
Although no countries currently use such weapons, the technology is available and human rights groups are campaigning to pre-empt deployment.

Great reading for statisticians and data scientists. R^2 has many flaws: it is sensitive to outliers and size-sensitive:an R^2 of 0.65 does not have the same meaning for a data set with 20 observations, than for a dataset with 10,000 observations. How do you normalize this?
R squared, also known as coefficient of determination, is a popular measure of quality of fit in regression. However, it does not offer any significant insigh…

Join +Nick Butcher, +Adam Koch and +Roman Nurik as they discuss various elements of Android design. This week, we'll highlight some design touches in our very own Google I/O 2013 Android app and do quick deep dives on sharing content on Android and interacting with the system bars in fullscreen UI situations.

Un aerogenerador que produce un 600% más de energía (acelerando el viento)
http://www.medioambiente.org/2013/05/un-aerogenerador-que-produce-un-600-mas.html

La empresa norteamericana SheerWind acaba de presentar un nuevo tipo de generador eólico, de nombre INVELOX, capaz de producir un 600% más de energía que las turbinas actuales. 
El novedoso diseño utiliza embudos para capturar el viento y dirigirlo hasta una turbina situada en el suelo. 
El viento entra por un embudo y según se va estrechando éste aumenta su velocidad hasta el punto en que es turbinado.
Las pruebas han demostrado que un viento de velocidad de 16 kilómetros por hora llega a la turbina con una velocidad de 64 kilómetros por hora. Después de pasar por la turbina el viento regresa al exterior con una velocidad de 24 kilómetros por hora...

The first in what promises to be an interesting series of articles. This seems a common pattern: "How could we have drifted into the second decade of the 21st century with absolutely no commercial NLP products? I believe the answer lies in three initially unexpected developments having little to do with NLP. Each enabled a previously near-useless technology to become a useful substitute, reducing the need for the real thing."
