Goals & Collaboration: Why are we here?

Skill swap...

• some of us are good with numbers and data

• some are good with visuals and interaction

• some of us with software or hardware

• there’s always more to learn

The Web is evolving fast, and now is a great time to share what we know...

me

• These slides prove I’m not a visuals guy

• Background in Web data standards (W3C)

• Before that, educational technology

• Here from mixed feelings: so much is becoming possible, so much still to learn

More proof

• Back in late ‘90s PCs and browsers were slow

• Open data was hard to find online

• Limited options for interactivity and ‘sharing’

• Building blocks were quite primitive

So much has changed even in last 3 years...

Web today: 3 trends

• Zero-installation browser-based apps

• New browser support for 2D & 3D graphics

• Open data, big data, social data, linked data...

Raw Materials

• modern browers can control your 3d card

• they can ask you where you are (and facing)

• play & process video, including from camera(s)

• negotiate access to Web-hosted data

• make use of 1000s of free software libraries

The data story

• It’s not just that your Web browser can make spinny shiny 3D skeletons

• ...but that it has access to all public medical resources in the world

• Not that it can make a 3D Twitter globe; but that Twitter ‘who follows who’ fits on a data stick.

• And that you can rent 100 servers at Amazon EC2 to process it, bought as easily as a book.

Big data, little data

• 6.5G: 1.47 ‘follows’ links from 41.7 million Twitter users (via an.kaist.ac.kr)

• 2.6G: English Wikipedia (2007 snapshot)

• Data access standards maturing (long list of acronyms go here)

• From e-Gov to Twitter, museums to maps, vast datasets are now available and increasingly interlinked...

Not just that LinkedIn make these great maps...

...but that gephi.org is free for anyone to try the sameSaturday, 7 May 2011

Contributing

• Just knowing that “Motion charts” are there in Google Spreadsheets

• Or about progress with WebGL + Javascript 3D

• Or how to access data from various sites

• Or that Gephi is the tool LinkedIn maps used

...can give us basics for collaboration and exploration(here today if you want to hack and try things, or later...)

Collaborating

• Looking for lightning talks, hands-on demos

• ‘Things that worked’ / ‘things that didn’t’

• Breakout groups - make use of the space

• Hack, chat, collaborate or listen

• If you figure something out later, please share what you learned in the Web...
