I learned yesterday that Alex Nichol passed away earlier this week. Alex was a Windows MVP and a prolific contributor to the Aumha.org site. Although Alex and I never met, I feel like I knew him through his writing, which was consistently well researched and easy to read. Just last week, in fact, I included a link to his article on Windows Product Activation in my post here, and every edition of Windows XP Inside Out includes a reference to his excellent explanation.of virtual memory in Windows XP.
The good folks at the Aumha forums have begun a thread in Alex’s memory. If you knew his work, stop by and add your thoughts.
Thank you, Alex, and farewell.

Alex, you are missed. There are few on the Inetrnet like you.
I was never more than a total stranger to you but you always helped me.
I never got to thank you properly.
We are all less well off now that you are not here.
