It's like a spreadsheet, immediately familiar, but much more suitable for complex data because it's hierarchical. It's like a mind mapper, but more organized and compact. It's like an outliner, but in more than one dimension. It's like a text editor, but with structure
This is a hierarchical organiser for tasks, notes, lists, weblinks and RSS feeds. You can categorise items, drag and drop stuff, share branches of your tree and more.
I have a
no asshole rulewhich is really simple: I really don’t want to work with assholes. So if you’re an asshole and you work on my team, I’m going to fire you. Now, if the whole team saysgosh, that’s awful. We want to work with as many assholes as we can!then we have a simple solution. I’ll fire me!

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.
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 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.
Clive Thompson has been getting some well-deserved attention for his recent Fast Company piece, in which Columbia University sociologist Duncan Watts explodes the hierarchical theory of social influence and trend propagation popularized by Malcolm Gladwell in the bestselling book The Tipping Point.

A mind mapper, and at the same time an easy-to-operate hierarchical editor with strong emphasis on folding. These two are not really two different things, just two different descriptions of a single application. Often used for knowledge and content mgmt.
PyTables is a package for managing hierarchical datasets and designed to efficiently and easily cope with extremely large amounts of data. You can download PyTables and use it for free. You can access documentation, some online examples and presentations

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.
This document describes an approach for handling hierarchical data in a relational database.
Most users at one time or another have dealt with hierarchical data in a SQL database and no doubt learned that the management of hierarchical data is not what a relational database is intended for.
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.
GraphML is a comprehensive and easy-to-use file format for graphs. It consists of a language core to describe the structural properties of a graph and a flexible extension mechanism to add application-specific data. Its main features include support of * directed, undirected, and mixed graphs, * hypergraphs, * hierarchical graphs, * graphical representations, * references to external data, * application-specific attribute data, and * light-weight parsers.
Apache Jackrabbit is a fully conforming implementation of the Content Repository for Java Technology API (JCR). A content repository is a hierarchical content store with support for structured and unstructured content, full text search, versioning, transactions, observation, and more. Typical applications that use content repositories include content management, document management, and records management systems. Version 1.0 of the JCR API was specified by the Java Specification Request 170 (JSR 170) and work on the JCR version 2.0 has begun in JSR 283. Apache Jackrabbit is a project of the Apache Software Foundation.
