BASICS. THE TECHNOLOGY

Each wave is an XML document. It can be rendered as html
Uses html 5
XMPP
Operational Transformation (OT). It defines a set of operations, transformations, and the documents they can be applied to

HTTP vs XMPP
REST
A mapping of CRUD operations on a RDBMS to:
GET
POST
PUT
DELETE
Web frameworks isolate us from seeing http at work

HTTP vs XMPP

HTTP vs XMPP
Decentralization
Presence
Presence data overhead
Real time possible. But this is not as big deal as it seems.

If we are doing web apps over HTTP, we are doing them wrong WRONG

The wave protocol is free and open source. You can run your own wave server
Alternatives (other real-time frameworks)
Tornado: extracted from friendfeed
Twister
Diesel

COMPONENTS

Robots - gadgets Robots are like participants

Waves are embeddable
In an application (example: desktop wave client)
Web page (example: substitute blog post and comments)

Sandbox vs standard wave
Standard ~ 100.000 users
You normally get invites
Quite a lot of activity
Sandbox: lucky few
- not that many people to test your extensions, but you can go to the standard wave for that

Wave Extension Design Principles
Make It Wave-y
Make It Easy to Use
Make It Easy to Install
Make It Look Good
Make It Useful — Or Fun!
(http://code.google.com/apis/wave/extensions/designprinciples.html)

Gotchas: Robot Wars
Problem: Because you can invite more than one robot into a wave, you can inadvertently end up building a new version of Robot Wars. For example, one robot could reply to another one's changes and vice versa.
Solution : give robots limited quota, so infinite loops will ultimately run out of steam.

SOCIAL ASPECT

Some A-list bloggers didn’t like it
Scoble:
Google Wave crashes on beach of overhype
Google Wave’s unproductive email metaphors
But, early adopters/geeks are not the audience.

User experience improvements will make great extensions
Pain points
You need to read through a lot of crap
It's hard to manage a long wave

Spam: Nobody can enter if they are not invited

Like twitter, it sits in an uncomfortable position

wavetiquette
proper wave etiquette is still forming
When is it ok to delete posts?
Should you edit your own response or respond to your response?
Starting new waves versus resurrecting old ones (and how to politely point people to older waves)

Hack away
2.5 hrs. Pair up
Let’s move to a place where we can walk around, see what others are doing, get back to coding
Come up with an idea. See blog post at rupy for step-by-step things to do
There’s a wave already started. Search for rupy
If you have no wave account, match up with someone who does

Scale to the entire web
Do reasoning with open word assumption
Retrieval in real-time
Go beyond logics
Use cases:
Real time city
Cancer monographs for WHO
Gene expression finding
