Resize images with Preview (Snow Leopard)

Alternative 1
A Quick way to resize images in batches could be find that Preview has that functionality. Open the whole batch of images in Preview; the images will all open in the same window with thumbnails visible in the sidebar.

Select all of the thumbnails in the sidebar (with Command-A, or click the first and then click the last while holding Shift). Next, from the Tools menu, choose Adjust Size. You’ll be presented with a dialog containing options to resize to all the common 4:3 and 16:9 screen sizes, as well as the option to define custom dimensions. Images are scaled proportionately and resampled by default.

Save the resized images, and you’re done!
Preview will prompt you to save any changes if you attempt to close the window.
Alternative 2
You can also use sips on the command line:
sips -Z 1024 *.jpg
will resample to a max of 1024 px for the long edge.
Note that sips rewrites images in place, so you should do this on a copy if you care.

Playing DVDs Ubuntu 10.04

Playing DVDs

In order to play DVDs you must install some additional software. Unfortunately, DVD support cannot be provided by default in Ubuntu due to legal restrictions in some countries.

Read about restricted formats before following the instructions below. There are some legal issues that you should be aware of.

Install the libdvdnav4, libdvdread4, gstreamer0.10-plugins-bad and gstreamer0.10-plugins-ugly packages.

If you would like to play encrypted DVDs, press Applications → Accessories → Terminal and type the following into the screen which appears, followed by the Enter key:

sudo /usr/share/doc/libdvdread4/install-css.sh

Enter your password if prompted. The libdvdcss2 package will be downloaded and installed from a website.

Insert a DVD into your drive. It should open automatically in the Movie Player.

borrar el código ya guardado.
Para hacerlo tenemos que presionar los siguiente:

  • De inmediato presionamos 9 8 1
  • La luz titilará 3 veces seguidas.
¡Perfecto! Ahora se habrá borrado la configuración del control remoto.

  • 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 presionamos "SELECT", de esta forma se guardará el código en el control remoto.
  • Ahora, si titila, se ha guardado correctamente. Para asegurarnos presionamos "ON", y el televisor deberá prenderse.
