An experimental matrix of Web 2.0 mashups.
Usage: Hover the cursor over any cell in the matrix. A small box gives details on mashups for that API combination. Top links in hover box bring you to that API's reference page. Links in body of hover box take you directly to the mashup. Not all combinations have mashups & only those with the 'º' indicator currently have entries. Cells at the intersection of same API (ex: Amazon+Amazon) list any other examples for that API.

Note that there are two views into the matrix: the default view shows only those APIs for which mashups have been added to the database. The second view shows all APIs regardless of whether there's currently a mashup registered. It's big. Definitions: What is a mashup anyway? As always, it's good to check Wikipedia's definition, but essentially a "mashup" is a web-based application built through (creative) combination of data from multiple sources. Often, but by no means always, this data is retrieved by using a vendor's API such as those listed here. (An API? Also at Wikipedia.) Some recent press may also help explain: BusinessWeek's "Mix, Match and Mutate", The Economist's "Mashing the Web". Background: This is an experiment. It is intended to be both a reference point and also a visualization. What you see here today will change both in content and form shortly. I am quite interested in seeing the 'space' in which mashups exist. Clearly, some APIs such as Google Maps, appear to be more widely used than others. UI Issues: Cross-browser support is good but not complete. Sometimes it can b

Hundreds of thousands of emails are sent every second, and yet, you wouldn't really know it because there aren't public-facing streams like that of Twitter. Outside your own inbox, how much email is there exactly? Yahoo, in collaboration with information visualization firm Periscopic, shows you how much email they process in real-time with this interactive feature. The initial view is a world map, and scaled bubbles represent how many emails were currently sent. Hover over continents for user geographic distribution and gigabytes sent. There's also trending topics from anonymized subject headers via streamgraph. The view is interesting as you can click on sections so that the surrounding streams split, so you get a sense of distribution along with details per keyword. The keyword data, however, isn't all that interesting for the most part. You'll see keywords such as online, free, and nights. Not too meaningful. There are a few exceptions though like Oprah and wars. There is also an option to include spam keywords with equally generic terms. Finally, if you go back to the map and keep on clicking, you eventually get to some fun facts about email, such as there are over sextillion ways to spell Viagra. All in all, it's a comprehensive view of how much email Yahoo handles that's fun to poke around.

After starting the test-suite it will automatically run a large number of small tests which will determine if your browser is compatible with a large number of CSS selectors. If it is not compatible with a particular selector it is marked as such. You can click on each CSS selector to see the results, including a small example and explanation for each of tests. Because it is technically not possible to simulate certain user interactions the test is limited to CSS selectors that are not dependent on user interactions. So this test-suite does not include tests for the following selectors: :hover, :active, :focus and :selection.

 hover above the R, G, and B bars and the colors (an even dozen, chosen to go well together) change, and you see a ghostly image of where the value will change to when you click.

Each bubble represents a single human-created tag describing an article. The size corresponds to the overall frequency that specific tag was used to describe articles about your query by labeling a related article. When you hover over a tag's bubble you will see the other tags it was used with. The thickness of that connection will imply how frequently that pairing occurred.
