my first 10 years and habits learnt

              History and learnings about the developments of computer systems, Application software and IT in India during the period 1965 2005 Prof D K Subramanian, IISc(rtd.) Professor,IIT,Bombay Visiting Faculty, IIMB,AIT,Bangkok,University of Manchester,PSTI, and several universities. Ex member, TCS Research advisory board Advisor, Karnataka government, banks, IDRBT,Jindal steel plant, Dept. of space, Government of India                  1. Introduction While Indian research institutions got into computer development and computational research from 1960 onwards, the first wave of computer usage by industries started by mid 1970s. The second and a short wave led to development of large computer centres in the seventies providing access and opportunities to larger groups of users from various organizations. This was mostly a government effort. The third wave started in the early 1980s. It started slowly b...

 Accelerators and technologies for green economy- the progress over decades. Prof DK Subramanian, IISc Abstract This paper shows how technologies, commerce and manufacturing developed over the past 50 plus years to create a sizable green economy. Initially , even with great push , the green concept didn’t pick up despite government support and law. Two developments helped in bringing the green economy into a central stage. One was the impact of the climate crisis and the second was the arrival of cost effective digital computers and fast optical and mobile communications. The green economy was built with synergistic purposes for all sectors. All sectors grew at a good pace. It was a win-win situation for manufacturing, services,health ,education,banking and fintech, commerce and governance. The digital economy was advantageous in many ways - cost reduction, higher quality, scaleup, increased reliability, global reach,optimal use of resources like minerals, water, talent,energy etc....

 Learnings from what happened to rural technology activities in India  Prof D K Subramanian IISc "Are we really homo sapiens - wise humans? Nobody disputes that humans today have a lot more information and power than in the Stone Age, but it is far from certain that we understand ourselves and our role in the universe much better. Why are we so good at accumulating more information and power, but far less successful at acquiring wisdom?" Yuval Harari    Nexus Rural technologies, a fancy area in the seventies in India,disappeared. Why? Indian Institute of Science set up a centre for development of rural technologies called ASTRA in 1974 and a support mechanism called KSCST in 1975 with involvement from the state government. While ASTRA developed technologies, KSCST took it to people and got engineering colleges in Karnataka involved in the development of technologies suited to rural tasks. The focus was on  renewable energy, efficient cooking stoves, mechanised a...

 The society is transforming and technologies are being invented at exponential pace. We need a new look at engineering. This is an attempt. What is engineering? My reflections 1 I requested the views of many. I got about 25 responses. About 25 % responded. My thanks to all those who responded. It shows every responder is concerned about this. I am glad.  The poser was what is engineering? Most seem to agree with the aim of engineering. I am not giving the individual  responses here,but I am giving a unified version which includes the views of most persons.  The responses fall in one or more  of the following categories: Outcome based Quality based Process based Approach based. Inclusion based. Let us look at the components of the definition. Outcome based -  Engineering solves real world problems. It produces useful / beneficial applications for the people.. Utility aspect is important. It is not a basic abstract activity ,but application based. ...
