Author: Addy Osmani. Publisher: h4xww.This video is NOT the book. It is a rendition of the book for the visually impaired. If it’s easier to listen to a computerized voice rather than to read, then this is an excellent resource. Follow the links to parts 2 and 3. We can only hope that h4xww will post additional parts to complete the book.
Author: zhirayr. Publisher: Monitor.Us.This article describes ten tips for improving website performance. While points 5 and 7 appear to contradict each other, they are both true. This is a good example of the tradeoffs we face every day when we try to improve performance, which gives me an opportunity to harp on about one of my favourite points: Measure performance in your own production environment. See Our Site Matters in Performance Perspectives for more information. [Using the free tools at monitor.us can give you your measurements with minimum fuss and bother, and give you ongoing monitoring as a free byproduct.]
a = 6 + 9 vs. a = 9 + 6. This one raises a few questions: Why is one option 30% slower than the other? Why is one the winner with some browsers and the other one wins with other browsers? This just goes to show us that we should never run performance tests just once. The test results can (and do) vary widely from one minute to the next.
Warren wrote his first computer program in 1970 (yes, it was Fortran). He earned his Bachelor of Arts degree from the University of Waterloo and his Bachelor of Computer Science degree at the University of Windsor. After a few years at IBM, he worked on a Master of Mathematics (Computer Science) degree at the University of Waterloo. He decided to stay home to take care of his newborn son rather than complete that degree. That decision cost him his career, but he would gladly make the same decision again. Warren is now retired, but he finds it hard to do nothing, so he writes web performance articles for the Monitor.Us blog. Life is good!
