When I go out of the house for a walk, uncertain as yet whither I will bend my steps, and submit myself to my instinct to decide for me, I find, strange and whimsical as it may seem, that I finally and inevitably settle south-west, toward some particular wood or meadow or deserted pasture or hill in that direction. My needle is slow to settle—varies a few degrees, and does not always point due south-west, it is true, and it has good authority for this variation, but it always settles between west and south-south-west. The future lies that way to me, and the earth seems more unexhausted and richer on that side. The outline which would bound my walks, would be, not a circle, but a parabola, or rather like one of those cometary orbits, which have been thought to be non-returning curves, in this case opening westward, in which my house occupies the place of the sun. I turn round and round irresolute sometimes for a quarter of an hour, until I decide for the thousandth time, that I will walk into the south-west or west. Eastward I go only by force; but westward I go free.

I must walk toward Oregon, and not toward Europe. And that way the nation is moving, and I may say that mankind progress from east to west.

Although there are numerous professional podcasting software packages currently available ($100 - $1000+), beginning podcasters may want to start with a freeware program. One of the most widely used free podcasting software programs is Audacity (http://audacity.sourceforge.net/), an open source sound recording and editing program with versions available for PC, Mac, and Linux operating systems. For Mac users another free podcasting program is GarageBand, found within the iLife package that comes with all new Mac OS X computers. Although older versions of GarageBand do not have the podcasting function, upgrades to the new, podcasting-ready GarageBand 4.1 are available in the iLife08 package for $90 (educational discounts available; http://www.apple.com/ilife/garageband/). For specific instructions on using GarageBand, an online video tutorial is available from Apple at http://www.apple.com/ilife/garageband/.

However, if the objective, for example, is to create a database of reusable lecture materials, then synchronizing the slides with the audio portion of the lecture and adding special effects (e.g., sound, video) may be required and will likely take at least as long as the lecture itself.
