In this age of computers, how software is controlling the life of humans. Now a days, people rely on computer/softwares more than their own brain and while doing this they forget that a bug in the software can do a harm for lifetime. Unfortunately not only it can mess-up things but also it can't take a corrective actions. On the contrary, human brain can handle such situation very comfortably. Having softwares is good and eased one's life but can end up to a big disaster also.

Below is a presentation, which explains how software bugs can turn into disaster. It gives a visually appealing account of how software bugs have been the root cause behind many of the technology/scientific disasters (the context is US space exploration & other telecom /nuclear related mishaps).

I want to appeal to all my fellow software developers to try your best to make your code bug free especially when you are writing code for such big things.
