His articles and columns in PCQuest and Dataquest magazines in 1993 and 1994 were among the first in the mainstream Indian computing press to inform thousands of readers about alternative operating systems, Unix, Linux, open-source software, Email, the Internet and the World Wide Web, years before Internet access was commercially available in India. These early articles  formed an important part of the PCQuest Linux Initiative that resulted in close to a million Linux CD-ROMs being distributed.
In pre-Internet India, Ashish created and operated the Primal Scream Bulletin Board System, and created the country's first inter-city Fidonet echo. Soon after the launch of Internet services in India, Ashish co-founded Sense/NET, a very popular ISP, with Vipul Ved Prakash. Prakash as of 2018 serves as a Director of Engineering at Apple.
