Every once in a while, as the number of people following me grows (thank you, each and every one), I like to revisit something that is fundamental to the high-tech industry but is often overlooked or not given the attention it deserves. This is one of those times, and the many-faceted nature of any application infrastructure is the topic. While much has changed since I last touched on this topic, much has not, leaving us in an odd inflection point. When referring to movies that involve a lot of CGI, my oldest son called it “the valley...
The rate of change in a mathematical equation can vary immensely based upon the equation and the inputs to the equation. Certainly the rate of change for f(x) = x^2 is a far different picture than the rate of change for f(x)=2x, for example. The old adage “the only constant is change” is absolutely true in high tech. The definition of “high” in tech changes every time something becomes mainstream. You’re working with tools and systems that even ten years ago were hardly imaginable. You’re carrying a phone that Alexander Graham Bell would not recognize – or know...
I find it amazing how many ways we can find to slice a pizza, skin a cat, or solve a technology problem. Truly amazing. Thus far in my multi-core odyssey, I have run into driver-based solutions, library-based solutions, and shim-based solutions to how to maximize use of multi-core. That's not to mention the upcoming version of C++, which is supposed to include the solution in the compiler. Each of these approaches has its strengths, though I think the best option would be for the OS to resolve the problem directly. It already has a scheduler and mechanisms for semaphores and...
