  • Welcome to Openhackindia
  • I am Pradeep BV. I work as an engineer in YDN. My talk is about making sense out of things on the web.
  • A lot of it since time immemorial
  • The world's earliest dated printed book, AD 868 - The intricate frontispiece of the Diamond Sutra from Tang Dynasty China, (British Museum) - http://en.wikipedia.org/wiki/Woodblock_printing
  • Printing press – enabled mass productionThis woodcut from 1568 shows the left printer removing a page from the press while the one at right inks the text-blocks. Such a duo could reach 14,000 hand movements per working day, printing around 3,600 pages in the process. Woodcut print dated 1423 of St. Christopher from Buxheim on the Upper Rhine- http://en.wikipedia.org/wiki/Printing_press
  • We then started printing musical notes – early signs of converting everything into data? The HarmoniceMusicesOdhecaton (also known simply as the Odhecaton) was an anthology of secular songs published by OttavianoPetrucci in 1501 in Venice. It was the first book of music ever to be printed using movable type, and was hugely influential both in publishing in general, and in dissemination of the Franco-Flemish musical style. - http://en.wikipedia.org/wiki/Odhecaton
  • And then we started transmitting dataOn 24 May 1844, after the line was completed, Morse made the first public demonstration of his telegraph by sending a message from the Supreme Court Chamber in the U.S. Capitol in Washington, D.C. to the B&O Railroad "outer depot" (now the B&O Railroad Museum) in Baltimore.
  • Across continents… the first internet?
  • And then we graduated into communicating…. 1876
  • And then came broadcasting Tesla demonstrating wireless transmissions during his high frequency and potential lecture of 1891. After continued research, Tesla presented the fundamentals of radio in 1893.http://en.wikipedia.org/wiki/Radio#History
  • And then the TV
  • The first group of networked computers communicated with each other in 1969, and ARPANET, or the Advanced Projects Research Agency Network became the start of the internet. Four U.S. universities were connected and became a research system by which computer scientists began solving problems and building the potential for worldwide, online connectivity. ARPANET had its first public demonstration in 1972 - http://www.elon.edu/e-web/predictions/150/1960.xhtml and http://personalpages.manchester.ac.uk/staff/m.dodge/cybergeography/atlas/historical.html
  • And the internet happened http://www.ddsmedia.net/blog/2009/10/40-anos-del-primer-mensaje-en-una-red-arpanet/
  • Closely followed by email… http://www.multicians.org/thvv/mail-history.html
  • In 1991, the World Wide Web was developed by Tim Berners-Lee (pictured at left) as a way for people to share information. The hyper-text format available through his Web made the internet much easier to use because all documents could be seen easily on-screen without downloading.
  • Mosaic was developed at the National Center for Supercomputing Applications (NCSA)[4] at the University of Illinois Urbana-Champaign beginning in late 1992. NCSA released the browser in 1993,[6] and officially discontinued development and support on January 7, 1997.[7] However, it can still be downloaded from NCSA -http://en.wikipedia.org/wiki/Mosaic_(web_browser)
  • It started gaining traction
  • And the venture capitalist's happened. 
  • So internet was no longer limited to just data
  • So internet was no longer limited to just data
  • And we become one tiny spec in the large information universe.http://electrokami.com/wp-content/uploads/2010/09/the-internet-in-real-life.jpg

  • “Reports that say that something hasnthappened are always interesting to me, becauseas we know, there are known knowns; there arethings we know we know. We also know thereare known unknowns; that is to say we knowthere are some things we do not know. Butthere are also unknown unknowns – the oneswe dont know we dont know.” Donald Rumsfeld, US Defense Secretary at a press conference at NATO Headquarters, Brussels, Belgium, June 6, 2002 Image: planetization.org 24
