One of the things that I have observed over the years is that most organizations do not do a good job of preserving and disseminating technical expertise. Critical information is often only known by a few individuals and there is no way to share it with others — Tribal Knowledge. This blog is an attempt to share some of the tidbits that I have learned over the years covering a wide range of technical topics.
