I have lost my Wiki for several times, but today I decided to reload it again.
From my opinion, I believe Wiki is the best tool for personal knowledge center in current days. I had built at least two wiki sites to record something, especially for the last one, I had a large plan and had already wrote some pages, while the Host vendor made a big mistake and caused my wiki site was dropped, and the worse was that they could not restore it!
Today I want to learn RAC within 20 days, at the same time, I think I need to take a note for the learning, so in the future I can find the necessary information in a short time.
It's sad to find that I almost forget all the statements or grammars of Wiki, so could not finish one page. Maybe I should review the Wiki help first.
