April 20, 2005 Ask Tourang a technical question .... Save your eyes Many times when I walk by co-workers' computers I notice that the refresh rate on many people's monitors is set too low. My eyes have become kind of sensitive to the 60 Hz flickering. The easiest way to see this flickering is to turn your head away and watch the monitor with the corner of your eyes. For some reason, still unknown to me, low refresh rates and the flickering become more visible when you look at your monitor from the side. If you are still not convinced and if you are curious to find out, right click on your desktop and select "Properties". On the next screen, across the top click on "Settings" and then select "Advanced". Again across the top click on "Monitor" and select the "Screen Refresh Rate". If your video card and your monitor allow higher than 60 Hz refresh rates, select a higher rate (72 Hz should be good enough). If you happen to work long hours on your computer, this will help you save your eyes in the long run. April 6, 2005
When I was at school, having a book of maps with different parts of the Earth was interesting but I could not wait until I got my hands on a spherical Globe. It was when I finally bought a Globe that I realized how
the
continents, oceans and even mountain ranges were inter-connected.
Soon after, however, my Globe turned into a soccer ball, and was
kicked around the house until my brother's foot poked a hole in it I guess the problem was that I could not find our house or even our street on the Globe and certainly I could not see my neighbors. Now all of that is getting to be possible, although we are not quite there yet. One of the companies that has been collecting sattelite images from all over the world is called "Keyhole". Last year Google bought them out and they are now offering images from every corner of the world to the consumers. Once you download their application, you will have the power to zoom in as close as possible and even get down to seeing streets and buildings in Manhatan or Shanghai. Wouldn't it be nice if you could zoom into Isfahan, let's say, take a good look at Menar Jonban, zoom out, and again zoom into Shiraz's Takhte-Jamshid and watch it from all different angles? Not all this imagery is there yet but they are adding to the images everyday. This service is inexpensive but it's offered to subscribers only. There is also a 7-day free trial version of Keyhole: www.keyhole.com One word of caution: the sattelite imagery depending on the location might be 2 or 3 years old and not all locations on Earth are covered, yet! Try it. You might enjoy it. Email your computer questions (all kinds of questions are welcome -- even personal ones, not!) About Tourang Birangi * *
