John C. McCallum
I was born in the house above. Since then, I have had a good life and a good career. Now I am retired as a permanent resident of Singapore. But, I spend a big portion of the year living in Bangkok, Thailand where my partner Vincent is working. I try to get to Canada to visit my family and friends each year - and sometimes I get to see the old house.
I notice that over the years everything seems to get renamed or relocated. London South Collegiate became London South Secondary School for a few decades, then was renamed back again. The University of Western Ontario became Western University. The UWO Physics Department became the Depatment of Physics and Astronomy. York's Experimental Space Science became Earth and Space Science. The College (later University) of Petroleum and Minerals became the King Fahd University of Petroleum and Minerals. Websites move around even faster! Keeping up to date with the world takes a little work.
I have loved computers since I tried designing a simple mecahnical relay computer as a young boy. I wrote my first computer program at the University of Waterloo in 1965 during one of their introductory days for high school students. When I decided that I would have my own computer one day, it seemed unreasonable. But, in 1975, I bought and soldered together an Altair 8800 with 256 bytes of memory. The Altair (Intel 8080 CPU) was programmed and entered bit by bit from switches on the front panel.
The tremendous changes in hardware technology have held my attention for many years. Prices have determined if I could buy, what I could buy, and what I should prepare to buy. I have collected data on prices over the years. The million dollar supercomputers of the 1980's are now outperformed by low cost smartphones which run more reliable operating systems, with much superior graphical capabilities.
And, now we get 4K flatscreen TVs to hook our computers to. I remember when we installed our first 21" black and white TV in 1955, and had access to one TV channel CFPL TV. Now, besides cable with uncountable channels, we have YouTube, and other download and streaming services letting us watch what we choose.
In the old farm house where I was born, we only had a radio for electronics
- no record
player, no TV, and a hand crank telephone, where our number was
two longs and a short. Technolgy has advanced quickly through the decades.
