Set (or change ) the hostname - Mac Os Lion

  • Open "System Preferences"
  • Click on "Sharing" icon

Como configurar el control de directv para que funcione con el Tv

Primer paso:
Si nuestro control ya fue utilizado en el decodificador a la vez, tenemos que
borrar el código ya guardado.
Para hacerlo tenemos que presionar los siguiente:
Movemos el interruptor a MODO TVPresionamos "MUTE" y "SELECT" juntos durante unos segundos hasta titile (parpadee) la luz verde del control remoto.De inmediato presionamos 9 8 1 La luz titilará 3 veces seguidas. ¡Perfecto! Ahora se habrá borrado la configuración del control remoto.
Segundo paso:
Dejamos el Interruptor en modo TV así tal cual estaba.Presionamos "MUTE" y "SELECT" juntos durante unos segundos hasta titile la luz verde del control remoto.De inmediato presionamos 9 9 1, titilará 2 veces.De inmediato presionamos 1 y vuelve a titilar.Apretamos ON y luego presionamos "CHANNEL +" (explico apretamos el de cambiar canales como si estuviésemos subiendo de canal), lo hacemos relativamente lento para que encuentre el código exacto.Cuando se apague presionamo…

Show all values in Numpy array

If an array is too large to be printed, (Scipy)NumPy automatically skips the central part of the array and only prints the corners:
>>> print arange(10000) [ 0 1 2 ..., 9997 9998 9999] >>> >>> print arange(10000).reshape(100,100) [[ 0 1 2 ..., 97 98 99] [ 100 101 102 ..., 197 198 199] [ 200 201 202 ..., 297 298 299] ..., [9700 9701 9702 ..., 9797 9798 9799] [9800 9801 9802 ..., 9897 9898 9899] [9900 9901 9902 ..., 9997 9998 9999]]
To disable this behaviour and force NumPy to print the entire array, you can change the printing options using
set_printoptions.

Dictionary of Methods/Functions (Python)

Construct a dictionary with String (or other) keys and unbound methods or functions as values. During execution, use the string keys to select which method or function to execute. Can be used for simple parsing of tokens from a file thru a kind of object-oriented case statement.

import string def function1(): print "called function 1" def function2(): print "called function 2" def function3(): print "called function 3" tokenDict = {"cat":function1, "dog":function2, "bear":function3} # simulate, say, lines read from a file lines = ["cat","bear","cat","dog"] for line in lines: # lookup the function to call for each line functionToCall = tokenDict[line] # and call it functionToCall()
It's embarrasingly simple really, but I use it a whole lot. Instead of functions, methods might also be used (self.method1), remember to follow the binding rules if you use methods dir…
