Docker ahora va a por los unikernels

Posted on by

unikernel

Docker es uno de los proyectos del software libre que más ha crecido en los últimos años, y su importancia ya comienza a verse reflejada en entornos empresariales de todos los niveles. Pero lejos de quedarse dormidos en los laureles, siguen buscando como avanzar y continuar siendo cada vez más competitivos, y en las últimas horas se produjo un importante anuncio al confirmarse la adquisición de Unikernel Systems.

Para quienes no sepan de que estamos hablando, decir que se trata de una compañía británica especializada en el desarrollo de unikernels, un enfoque diferente en lo que a sistemas operativos se refiere ya que se utiliza en sistemas embebidos y en dispositivos de bajo consumo energético como puede ser el caso de IoT (Internet of Things, el Internet de las cosas) cada vez más presente en la vida diaria.

Para entender mejor su alcance podemos pensar en el unikernel como un pequeño contenedor, un sistema operativo embebido basado en librerías (LibOS), una idea que ya tiene algunas décadas de existencia. Los unikernels son un enfoque nuevo en cuanto a las plataformas ya que permite a los desarrolladores crear apps livianas que se compilan utilizando únicamente aquéllos componentes del sistema operativo que le son necesarios, y ahora en Docker quieren universalizar está tecnología tal como hicieron con los contenedores, ofreciéndola a los desarrolladores y emprendedores.

Es que los unikernels prometen apps livianas y mucho menos código que escribir, pero fundamentalmente mucho menos código que mantener, algo que resultará muy atractivo ya que no solo implica menos recursos sino también menos posibilidades (estadísticamente al menos) de sufrir vulnerabilidades. En todo caso, se trata de una tecnología con muchísimas posibilidades innatas, las cuales desde luego seguramente se verán aumentadas a partir del hecho de formar parte de Docker.

‘Far Cry Primal’s’ Demo Was Fun For 20 Minutes… What About 20 Hours?

Posted on by

Far Cry Primal takes a bold step in a new direction and for them it is paying off. I played the demo at Sony’s PlayStation experience and before this demo I had my doubts, now… not so much. Ignoring the old argument that Far Cry Primal looks like another Far Cry game (the same argument could be made about every franchise game ever…), this takes us into a very well fleshed out world that we’ve almost never gotten to explore in video games before. You play as the first human being to ever tame beasts making you part of the very beginnings of civilization.

BlackRock’s First Israeli ETF ‘iShares TA25’ Listing On LSE Could Appeal

Posted on by

Does the iShares TA25 Israel UCITS ETF from BlackRock, which became the first Israeli exchange traded fund (ETF) to list on the London Stock Exchange (LSE) this Wednesday and offers institutional and retail investors access to the Tel Aviv Stock Exchange’s (TASE) flagship index, the Tel Aviv 25 Index (TA-25), merit investing in? It ticks certainly a few boxes.

Culture Wars: Star Wars Underperforms in China and the Differences Emerge

Posted on by

Globally, Star Wars: The Force Awakens has generated $1.8 billion (as of January 18, 2016) since it opened in North America throughout the month of December 2015. The movie opened in China on January 9th and was top of the box office for two weekends in a row. It ranked 2nd in opening day revenues, behind the 2015 launch of Fast and Furious 7, a movie that holds other revenue records as well. The Force Awakens did take the top ranking for a movie to have opened on a Saturday night, however. And, it surpassed $100 million in Chinese ticket sales this week (total non-US revenues have exceeded $1 billion thus far). Disney, the owner of Star Wars as of 2012, benefits from sales of movie tickets, Disney Interactive’s Infinity Star Wars line, licensed products, and digital games. In China, consumers appear to love the licensed products, moderately enjoy the movie, and are ho-hum about the digital games (though the official Electronic Arts console game Star Wars: Battlefront has yet to be approved or launched in China).

Apple’s Gamble Needs Samsung For New iPhone Technology

Posted on by

The latest report from Korea’s ET News is that Samsung’s display division has won the race to be the primary supplier for OLED display panels destined for a next-generation iPhone. Following Samsung’s weak guidance for Q4 2014 earnings, this advance order, likely to be in place for a number of years, will help stabilise the finances of the South Korean company.
