Although the introduction of this article is overly simplified in terms of the changes in library technology (I couldn’t help but laugh a little in a couple of places) , once you’re past that, the rest is a good little overview of some of the more popular opensource products. I’ve hotlinked and listed the products below, the article gives a more indepth overview.
The products are:
ubuntu (ms windows alternative based on linux)
firefox (web browser; ms internet explorer alternative)
openoffice (productivity suite with wordprocessing, presentation, and spreadsheets; ms office alternative)
thunderbird (e-mail + rss reader; ms outlook express alternative)
songbird ( media player; windows media player alternative?)
gimpshop (image editing; adobe photoshop alternative)
pdfcreator (pdf creator; adobe acrobat alternative)
Audacity (audio burning software)
avidemux (video creation)
I’ve talked a little about evergreen and vufind here. At home, I still run MS for the operating system and commercial stuff for my server; but then everything else is opensource or web based services (Firefox, gimp, ghostwriter+pdf, openoffice, etc.) Setting up these products on a small personal computer is fairly easy (really!). I’m not sure how that would translate to a large network, which could possibly be a hidden cost factor: installing these, configuring them as needed, and upgrading. Of course, admins already have to do that for any programs that they support. Training issues (oh the fun of trying to teach a group of web editors to use Drupal…) as well as potential security risks given the opensource nature would be other potential costs.
