Schemaball is a flexible schema visualizer for SQL databases. The purpose of Schemaball is to help visualize the relationships between tables. Tables are related by foreign keys, which are fields which store the value of a record field from another table. Figure | A MySQL schema of our sequencing LIMS database. Schemaball produces images called schema balls. Schemaball is free software, licensed under GPL. I am not longer actively working on Schemaball. Schemaball was published in SysAdmin Magazine (Krzywinski, M. I've since been using the circular composition form in my Circos project, which applies this layout to visualizing genomes (Circos is particularly popular in the field of comparative genomes, in which relationships between two or more genomes are analyzed and displayed). Ensembl balls!

Mapping the Internet The increased use of peer-to-peer communications could improve the overall capacity of the Internet and make it run much more smoothly. That’s the conclusion of a novel study mapping the structure of the Internet. It’s the first study to look at how the Internet is organized in terms of function, as well as how it’s connected, says Shai Carmi, a physicist who took part in the research at the Bar Ilan University, in Israel. “This gives the most complete picture of the Internet available today,” he says. While efforts have been made previously to plot the topological structure in terms of the connections between Internet nodes–computer networks or Internet Service Providers that act as relay stations for carrying information about the Net–none have taken into account the role that these connections play. “Some nodes may not be as important as other nodes,” says Carmi. With the core connected, any node is able to communicate with any other node within about four links.

Web Trend Map 4 by Oliver Reichenstein The has been featured all across the web from TechCrunch to BoingBoing, and Gawker. Now the latest version of our popular Web Trend Map is up for grabs.—The Web Trend Map plots the Internet’s leading names and domains onto the Tokyo Metro map. Domains and personalities are carefully selected through dialogue with map enthusiasts, and every domain is evaluated based on traffic, revenue, and character. Sold out – Sorry, the Web Trend Map 4 is no longer available. We grouped together closely associated websites, ensuring that every domain is on an appropriate line. The map has been printed by the same printer that prints Apple’s ads in Japan, so you can be sure its handled by the best.
