Social Media Playground

1. Draft Social Media Playground Dan Ryan Mills College Spring 2012

2. Today • Announcements (talk, summer, lab) • Glitches? • Servers and Clients and Feeds • One to many, many to one • Synchronous/Asynchronous • Push/Pull • Email • Wikipedia • Blogs • Twitter • Facebook • YouTube • Explore & Questions & Experience

3. Servers and Clients • Server = program/machine that accepts and fulfills requests over a network • Client = program (usually with UI) that translates user request into server request & displays received data • “conversation” follows a protocol (rules for how you ask for things and how you interpret what you get)

4. Examples • Safari, Firefox, Chrome are web clients • Apache is web server software • Mills has a web server machine that runs this software (or some other) • HTTP is the protocol they use to converse

5. Feeds -- RSS • RSS=really simple syndication • “syndicate” ~ distribute • “feed” = server that can be “followed” • User gives URI of feed to “reader” or “aggregator” • Reader checks regularly for updates
