I was in an office next to Andy’s at Sun.  When I first came to Sun as a Program Manager he was so kind and helpful to me. I never kept a tidy desk, but it could not compare to Andy’s.  It never ceased to amaze me when I went to him for some advice, he could always give any information needed quickly even if it required reaching into the middle of a large stack.  He knew exactly where things were, even though his desk appeared chaotic. He was so intelligent, kind, and helpful.  He was a wonderful mentor and helped many engineers develop in the group.  He was not a political guy, and he always wanted things in the group to be right and fair.  Andy was a great guy, always looking out for others.

I had the pleasure of working with Andy for a number of years at SUN Microsystems. I personally learned so much from Andy, and not just the technical bits. His wry sense of humor was unique, and so were his sharp insights into technical design challenges and organizational malfunctions of all kinds. Above all, his utter lack of pretense and having the confidence and integrity to stand up and say what he really thinks, is what i found absolutely inspiring.

I did not have the privilege of knowing Andy at a personal level. However, he did mention his family and specially his daughter Fran, who he was very fond of. I wish his family strength and courage to deal with this loss.  I am saddened by his departure, but i am also grateful to know that he went in peace.

You will always live in our memories, Andy. Goodbye and Bon Voyage.

Andy was in the top 1% of humans.  At work he was a paragon, a consummate team player; the best co-worker a person could have.  Andy was open, honest, and direct, but always kind, patient, and respectful.  And funny!  He had an amazing talent for being pragmatic when it came to getting a product shipped.  Andy was also lovable and charming, a good friend who will be sorely missed.

Always smiling, approachable, and welcoming, Andy was my go-to architect with a messy desk and a twinkle in his eye. No technical problem was complex enough to withstand his ability to cut through noise to focus on the essential to solve complex, hairy problems elegantly. We will all miss you.

Andy was someone I really enjoyed working with. He would have these great suggestions for changes to code that I "owned", and he always explained them in a clear and friendly manner.

Andy was an enthusiastic mentor and superb teacher.  He taught me the truth about the true complexity of a well-implemented distributed system.  His instinct for managing details and foreseeing the blind spots and abstract inconsistencies that others missed was a singular talent that I doubt I’ll ever see matched. It was a great privilege to learn from and work with him.

Andy was a brilliant man who is gone much too soon. He was my mentor and role model in the Sun Cluster team. Working closely with Andy on the product design was a highlight of my career. Andy was always generous, funny, patient, and very insightful, and he inspired others to be their best.

I admired the courage and strength Andy had to fight his illness. This will be the example I will remember forever.

I was blessed to get to work with Andy.  He was one of the most talented engineers I ever met.  He also had a wonderful sense of humor.  He taught me many things about high availability and clustering and he also taught me to appreciate the Lazlo Letters.  I loved knowing him.

I worked with Andy in the Sun Cluster (SC) team for eight years, my entire tenure at Sun. He was one of the SC architects, and the technical expert on distributed storage which I did not know much about. My first project was on SCSI devices, and I was impressed by his vast knowledge in the area, and his ability to explain it succinctly! I learned a lot from him. May his soul rest in peace.

He is one of my favorite people and I feel blessed to have spent time with him.
