This is an old presentation of me. In my office every tech guy must choose a topic and should give a presentation on that topic. The topic can be anything related to software engineering or science. In August 2008 I took a seminar. My topic was Erlang. On that time very few people in my country heard about the language. I tried to give an introduction to that language. The presentation is just to introduce Erlang. I used many photographs and links just to make the seminar interesting. If anything objectionable is found please let me be known to it. Thanks for your co-operation.
