A better way to think of a manager is as a servant, like an editor or a personal assistant. Everyone wants to be effective; a manager’s job is to do everything they can to make that happen.

How to use ejabberd's pubsub module | ejabberd Community Site
by greut
Pubsub nodes are organized in a hierarchical tree, similar to a file system. mod_pubsub imposes a special structure on this tree. There is a special node, pubsub/nodes, that contains all other created nodes. Nodes of users have names like home/server/username/whatever. If you try to create a node whose name doesn't fit that pattern, you will get an error. If you don't specify a name (i.e. create an instant node), the server generates a name that fits this pattern
Some says that it's the future of feeds, at least server-to-server subscriptions.

Hypergraph - Hyperbolic graphs and trees : Home
by parmentierf
& 2 others
HyperGraph is an open source project which provides java code to work with hyperbolic geometry and especially with hyperbolic trees. It provides a very extensible api to visualize hyperbolic geometry, to handle graphs and to layout hyperbolic trees.
As soon as you want to look at large data volume that has a hierarchical structure, you will find hyperbolic trees very useful - they show more data than standard tree representations like your favorite explorer, and they have a great look and feel.

DBAzine.com: Trees in SQL: Nested Sets and Materialized Path
by ogrisel
& 1 other

Relational databases are universally conceived of as an advance over their predecessors network and hierarchical models. Superior in every querying respect, they turned out to be surprisingly incomplete when modeling transitive dependencies. Almost every couple of months a question about how to model a tree in the database pops up at the comp.database.theory newsgroup. In this article I'll investigate two out of four well known approaches to accomplishing this and show a connection between them. We'll discover a new method that could be considered as a "mix-in" between materialized path and nested sets.

What I would like to focus on in this article is a different approach, commonly referred to as the Nested Set Model. In the Nested Set Model, we can look at our hierarchy in a new way, not as nodes and lines, but as nested containers.
