Just today I came to know about the sad news... Like many of us here, I did not know him personally. However, from his talks one can see that he was a very humane person. Hardworking and devoted to a cause that he truly believed in, to bring a grain of sand in this lonely world. Always with great humbleness. Many of us who struggle and struggled with many technology-related addictions will always be immensely grateful for his contribution... and willing for more like him to follow his path.
