When we used to organise small get-to-gethers of the free and open source software (FOSS) community ( Goa engg college linux user group - GEC - LUG) he used to be an active volunteer and help in arranging the demo of interesting free and open source software, engineering related like QCAD, productivty and publishing related like Open Office, LaTeX etc.., help in organising install-fests on student laptops, free 24 hour demos in the studen thostel and so on.
Later on with the activities of thee Nature Club of GEC of which Santosh was a strong member, we had many treks to different locations in goa, scenic, at least five of them over two years and we enjoyed those treks very much. It also made our friendship grow stronger and long lasting.
Some students create such a lasting impression in college that they do not go out of your minds for many years .. Santosh is one of those students.. Lot of fond happy memories ..
