El Baúl Del ITPRO

Buenas tardes,

Ayer en la presentación de Windows Server 2012 me gusto bastante la demo que realizo Dani Matey en la que interactuaba con una máquina virtual desde twitter. Dani uso system center orchestrator para relizar la demo y la verdad es una gozada ver como es posible hacer un workflow en orchestrator sin tener ninguún conocimiento de desarrollo.

Pero como el orchestrator no es un programa que tiene todo el mundo me he decidido a investigar un poco sobre la manera de twittear desde Power shell y la verdad esque me ha sorprendido grantamente lo sencillo que es.

Esto nos da un pespectiva de la potencia que ha adquirido power shell en la versiones de windows server 2012 y windows 8 donde podemos realizar casi cualquier acción que nos imaginemos desde power shell.

Una vez hecho esta pequeño intro, os dejo el texto de un script supersencillo de power shell divido en varias funciones (dependiendo de la acción que queramos realizar. He preferido hacer un copy/paste del texto antes que subir un enlace el fichero porque entiendo que en muchos casos podéis usar solo una función y no todo el script.

Buen find de semana.

#lang: restricts tweets to the given language, given by an ISO 639-1 code
#rpp: Results per page, (max 100)
#page: the page number (starting at 1) to return, up to a max of roughly 1500 results (based on rpp * page)
#since_id: returns tweets with status ids greater than the given id.
#geocode: returns tweets by users located within a given radius of the given latitude/longitude, where the user’s location is taken from their Twitter profile. The parameter value is specified by «latitide,longitude,radius», where radius units must be specified as either «mi» (miles) or «km» (kilometers). Ex: http://search.twitter.com/search.atom?geocode=40.757929%2C-73.985506%2C25km. Note that you cannot use the near operator via the API to geocode arbitrary locations; however you can use this geocode parameter to search near geocodes directly.
#show_user: when «true», adds «:» to the beginning of the tweet. This is useful for readers that do not display Atom’s author field. The default is «false».
