Which is the oldest computer?? Well some would say ENIAC, others would say Colossus, what ever it is, im sure its not my computer :) because i just purchased it, didnt invent it :) The Answer is : " Antikythera " It is an ancient mechanical computer which was being in use around 200BC (around 2000 years ago!!!). This device has been recovered from Antikythera Wreck (near greek island called crete), hence it gets its name "Antikythera". It is figured out that it was being used for two purposes, Astronomical and Astrological purposes. This device was used by greek astronomers for their research works! Above is the picture of the recovered Antikythera. Scientists say, there are large number interconnected gears and is very complicated than a modern swiss watch!!. This device was recovered in 1900-1901. It took around 70 years to understand the complete inner workings of the Antikythera. In 1974, Price published a paper "Gears fr
Well his post will be regarding some tips on coding style. I googled about this topic, checked many sites, read many posts, finally made a list on them... Meaningful names to variables -- i.e., name them meaningfully so that it corresponds as closely as possible to verbal description of its usage. Maintain a labbook from the beginning of a project to the end. Code each variable so that it corresponds as closely as possible to a verbal description of the substantive hypothesis the variable will be used to test. Errors in code should be corrected where they occur and the code re-run. Separate tasks related to data-manipulation vs data-analysis into separate files. Each program should perform only one task. Do not try to be as clever as possible when coding. Try to write code that is as simple as possible. Each section of a program should perform only one task. Use a consistent style regarding lower and upper case letters. Use
