I tried and really didn't like Netvibes, but I have already switch to Awesome New Tab Page, an extension for Chrome. Loads of plugins like a gmail client, weather, RSS readers, all in a grid you can lay out yourself.

Takes a bit of work to copy your setup across computers though - the layout comes across if you're signed in to sync your plugins, but not the RSS feeds themselves.


Can Machine Learning Replace Focus Groups? 93

itwbennett writes "In a blog post, Steve Hanov explains how 20 lines of code can outperform A/B testing. Using an example from one of his own sites, Hanov reports a green button outperformed orange and white buttons. Why don't people use this method? Because most don't understand or trust machine learning algorithms, mainstream tools don't support it, and maybe because bad design will sometimes win."

eBay Makes Huge Gains In Parallel Efficiency 47

CurtMonash writes "Parallel Efficiency is a simple metric that divides the actual work your parallel CPUs do by the sum of their total capacity. If you can get your parallel efficiency up, it's like getting free servers, free floor space, and some free power as well. eBay reports that it amazed even itself by increasing overall PE from 50% to 80% in about 6 months — across tens of thousands of servers. The secret sauce was data warehouse-based analytics. I.e., eBay instrumented its own network to do minute-by-minute status checks, then crunched the resulting data to find bottlenecks that needed removing. Obviously, savings are in the many millions of dollars. eBay has been offering some glimpses into its analytic efforts this year, and the PE savings are one of the most concrete examples they're offering to validate all this analytic cleverness."

Every program is a part of some other program, and rarely fits.
