Social Reputation Design Pattern Described by Yahoo

 

Reputation Design Pattern

“A person participating in a social structure expects to develop a reputation and hopes for insight into the reputations of others, but each designed model of participation and reputation embodies its own set of biases and incentive structures. Balancing these forces determines in large measure the success or failure of a social system.”

I love this “shell” interface to google.

ActionScript 3D (pv3d-like) Data Visualizations

Very interesting  3d visualizations here over at http://www.bestiario.org using their own 3D framework.

Visual Comparison of Sorting Algorithms

Love the visual representation (little applets) of the sorting and it’s a great sort reference:

Sorting Algorithms

Quoting, “We all know that Quicksort is one of the fastest algorithms for sorting. It’s not often, however, that we get a chance to see exactly how fast Quicksort really is. The following applets chart the progress of several common sorting algorithms while sorting an array of data using in-place algorithms…”

JavaScript Info Visualization Toolkit

The JIT is an advanced JavaScript infovis toolkit that was based on 5 papers regarding different information visualization techniques. The JIT implements advanced features of information visualization like Treemaps (with theslice and dice and squarified methods), an adapted visualization of trees based on theSpacetree, a focus+context technique to lay Hyperbolic Trees, and a radial layout of trees with advanced animations (RGraph).

Some very nifty tools here:http://blog.thejit.org/?page_id=14

In particular, check out the spacetree demo 

Also a nice bibliography.

Java FX

I generally hate java, but something to watch with the Java FX from Sun.  Here is a terrible marketing description(ugh)- note the screens of your life - idiotic , ”Java FX is a powerful client technology for creating rich Internet applications (RIAs) with immersive media and content across multiple the screens of your life.”

Here is a designy, and incredibly lame UI presentation by sun here: http://javafx.com

And don’t you lust love when they have to make quicktime movies of their technology? 

Unobtrusive JavaScript with jQuery

I’ve been in drupal world again, which happens to use the jQuery JS libraries. Simon Willison has some great resources and links here: Unobtrusive JavaScript with jQuery

The latest jQuery. jQuery is a fast, concise, JavaScript Library that simplifies how you traverse HTML documents, handle events, perform animations, and add Ajax interactions to your web pages.

EC2 Persistent Storage

This is the main issue I currently have with Amazon’s EC2: the lack of persistent storage. However, according to this press release,

“This new feature provides reliable, persistent storage volumes for use with Amazon EC2 instances. These volumes exist independently from any Amazon EC2 instances, and will behave like raw, unformatted hard drives or block devices, which may then be formatted and configured based on the needs of your application. The volumes will be significantly more durable than the local disks within an Amazon EC2 instance. Additionally, our persistent storage feature will enable you to automatically create snapshots of your volumes and back them up to Amazon S3 for even greater reliability.”

Here’s the thread

Papervision Typography

This is kinda(no really) buggy, and not ready for primetime… but… the potential.

The actual concept is weak as well - just check out the UI - angles/transitions/etc.
