The igraph library for complex network research

igraph is a free software package for creating and manipulating undirected and directed graphs. It includes implementations for classic graph theory problems like minimum spanning trees and network flow, and also implements algorithms for some recent network analysis methods, like community structure search.

WordNet - About WordNet

WordNet® is a large lexical database of English, developed under the direction of George A. Miller. Nouns, verbs, adjectives and adverbs are grouped into sets of cognitive synonyms (synsets), each expressing a distinct concept. Synsets are interlinked by means of conceptual-semantic and lexical relations. The resulting network of meaningfully related words and concepts can be navigated with the browser. WordNet is also freely and publicly available for download. WordNet's structure makes it a useful tool for computational linguistics and natural language processing.

Unqualified Reservations: Wolfram Alpha and hubristic user interfaces

My guess is that if there is any "next thing" in search interfaces, it will come not from smarter UIs, but from dumber ones in which the user does more work - the Graffiti effect. If a small quantity of user effort can produce a substantial improvement in user experience (which is a big if), the user will accept the bargain. Hey, it made Jeff Hawkins rich.

L0phtCrack - Windows & Unix Password Auditing & Recovery

We made L0phtCrack available once again because hard core security professionals have found it to be the best and have yearned for up-to-date OS support. After 12 years, L0phtCrack is still a mainstay at many leading security consulting firms and the US military.

etalog: Psychology research with Mechanical Turk

With Mechanical Turk, it's possible to do in one shot a study that would otherwise require a meta-analysis of several studies across particular locations or demographics. With more consistent data and larger populations, data can be reusable.

CAIDA : tools : visualization : walrus

Walrus is a tool for interactively visualizing large directed graphs in three-dimensional space. It is technically possible to display graphs containing a million nodes or more, but visual clutter, occlusion, and other factors can diminish the effectiveness of Walrus as the number of nodes, or the degree of their connectivity, increases. Thus, in practice, Walrus is best suited to visualizing moderately sized graphs that are nearly trees. A graph with a few hundred thousand nodes and only a slightly greater number of links is likely to be comfortable to work with.
