In the interest of interesting quotes, a quote that I found in the “Oracle Tuning the Definitive Reference Second Edition” book on page 995:
“In the 1970s, Moore’s law was introduced, stating that processor costs were always falling while speed continued to improve. However, as Oracle professionals, we must understand that Moore’s law does not apply to RAM. While RAM costs continue to fall every year, the speed of RAM access is constrained by silicon technology and did not improve over at least three decades as shown in Figure 17.1.”
What, if anything, is wrong with the above quote? While my review of the book only provides an in-depth technical review of the first 200 pages of the book, this blog article series will dig into some of the pages that were not specifically included in the review.
The point of blog articles like this one is not to insult authors who have spent thousands of hours carefully constructing an accurate and helpful book, but instead to suggest that readers investigate when something stated does not exactly match what one believes to be true. It could be that the author “took a long walk down a short pier”, or that the author is revealing accurate information which simply cannot be found through other resources (and may in the process be directly contradicting information sources you have used in the past). If you do not investigate in such cases, you may lose an important opportunity to learn something that could prove to be extremely valuable.
