I've finished repairing some minor corruption on my Wiki on a Stick. It took a total of about five or six hours, but I got to listen to one of my audio books as I worked.
What is a wiki on a stick? Well it is your own personal wikipedia on a thumb drive. It starts with no entries but can quickly be filled with information useful to the owner. I'm filling up mine with role-playing campaign notes, old blog entries, and other writings of mine. I've even added journal entries and plan to add research notes for my family tree.
Basically it is for personal information management. It is also great for note taking since you can link individual words in your notes to pages given more information and categories to organize various entries.
Sure there are online sites where you can set up your own wikia. However, those have the disadvantage of being online instead of hidden away on a thumb drive. A wiki on a thumb drive can be more secure and can be used on your laptop where no wireless is available.
As with anything else related to computers just be sure to make regular back-ups. that's what saved me countless hours fixing my file the last couple of days.
And which audio books have I been listening to? Harry Turtledove's After the Downfall as well as some episodes of the old radio show Dimension X.
