Universally Unique Identifier


Almost all the programming languages have a library function for generating a Universally Unique Identifier (UUID). These libraries are responsible for generating an identifier that is unique in the whole universe. How do these libraries go around the complete universe and generate a unique identifier in just a few milliseconds?

I am passionate about programming and feel amazing when I see people using the software I have contributed in. I believe it is essential to write high quality code, which is easy to understand and test. I am still a work in progress and decided to document and share some of my learnings with everyone. Apart from that, I like to read books, and so you might find a lot of book reviews on my blog. I am working as a Software Engineer at Oracle since post-graduation from IISc Bangalore, and happily married :)
