Federated Wiki by Ward Cunningham

Wiki(WikiWeb) creator is working on new idea,
that makes Wiki "distributed".
Conceptually this makes sense,
but its success will depend on implementation.

The challenge is not parallel editing, but "merging".
Interesting idea here is "side by side",
"drag-and-drop" view of multiple versions of same document.
So it is humans doing merge, not algorithms.

Netflix new API: post-REST, Functional, Reactive

At Netflix scale (that is at peaks 1/3 of internet traffic in USA),
even REST style of communication is not efficient and good enough.
So they have internally started implementing more optimized style of communication
that is more efficient on network traffic,
and more efficient on server side processing.

The first problem with REST is a need to send multiple requests
(and wait for responses) that is very dependent on specifics of
more than 800 types of supported devices.

The solution are custom, more high-level messages,
that are implemented for and by client team and running on severs
to prepare complete data and return in one optimized message.

Second issue is how to make this server-side processing efficient,
without creating too much additional load on servers.
For this they have implemented "Reactive Functional Programming",
that is first introduced by Microsoft Research's Eric Meyer as RX Framework
and added to .NET and other tools.

Netflix has adopted same style, and implemented for Java platform
but not Java language: instead they are using Grails in JavaVM.

All we need now is a clever catchy name for the new style protocols,
and a simplified portable open source implementation, i.e. for Node.js :)
If that can be a part of some PhD thesis (like REST was), even better :)

Would "web sockets" and "comet-style" connections be effective here?

JavaScript and Web Frameworks

A useful reference list (from a year ago):

The Big Glossary of Open Source JavaScript and Web Frameworks with Cool Names - Scott Hanselman:
"...JavaScript projects that are basically just hip sounding words with ".js" added to the end, it's a little overwhelming. Seriously, just pick a word out of the dictionary at random and that's the name of an up and coming JavaScript library..."
