Apologies that content is no longer regularly updated here. Time is precious, especially with a family. And my career has shifted focus to Security.
Over the last 15 years, I have received countless emails from people all over the world. I am grateful and humbled that this site has aided people in their studies and careers. I hope that continues.
I intend to keep this site online permanently, even without updates. And the material will remain free - always.
Take care, and don't forget to say hello.
