LHS Episode #094: Arsenic and Old Pi

Introduction:

• No music this episode.

• It’s the night before Halloween and we’re off to another spooky episode of LHS with our hosts starting with a ramble about horror movies. It’s a trick AND a treat!

Topics:

• Creating a desktop wallpaper slideshow in GNOME:

It’s actually a built-in feature of GNOME. Briefly, here are the steps:

• As root, create a new directory in /usr/share/backgrounds (any name you want).

• In that directory, place your desired background images (or links to them).

• There’s already a directory in /usr/share/backgrounds called cosmos which you can use as a guide.

• Copy background-1.xml from the cosmos directory into your new directory and edit it to specify your images.

More information can be found in this askubuntu thread. Be sure to read through all the comments.

• Richard points us to one of many articles about ham radio operators helping out during and after Hurricane Sandy. Our sympathies to the victims of hurricane.

• More about EchoLink and Linux: Richard found the CQiNet project, which includes two applications, Echolinux (an EchoLink client for Linux) and The Bridge, an iLink/EchoLink compatable conference bridge. Of course, there is still the svxlink package, which includes the Qtel Echolink client.
