These are really interesting/useful for explaining how the code that executes isn’t the code you wrote as well as making you think about performance. A good example is the last one. As Mr Sutter explains, the swap from 80’s architectures such as the VAX to modern systems was accompanied by a real change in speed of processor but without a large change in memory latency. As a result “elegant” algorithms that were right for 70s and 80s hardware are totally wrong for modern cache laden systems.
I stumbled over them a while ago, and then spent ages trying to find them again for a colleague. For some reason my google-fu was sadly deficient at work, but once sat back at home I found them within 15 minutes of trying.
