The guinea pig (Cavia porcellus), also commonly called the cavy, is a species of rodent belonging to the family Caviidae and the genus Cavia. Despite their common name, these animals are not pigs, nor do they come from Guinea. They originated in the Andes, and studies based on biochemistry and hybridization suggest they are domesticated descendants of a closely related species of cavy such as Cavia aperea, C. fulgida, or C. tschudii, and therefore do not exist naturally in the wild. The guinea pig plays an important role in the folk culture of many Indigenous South American groups, espe...
42 (forty-two) is the natural number following 41 and preceding 43. The number has received considerable attention in popular culture because of its appearance in The Hitchhiker's Guide to the Galaxy, as the "Answer to the Ultimate Question of Life, the Universe, and Everything".
In mathematics
Forty-two is a pronic number and an abundant number; its prime factorization 2 · 3 · 7 makes it the second sphenic number and also the second of the form { 2 · 3 · r }. As with all sphenic numbers of this form, the aliquot sum is abundant by 12. 42 ...

In graph theory, a clustering coefficient is a measure of degree to which nodes in a graph tend to cluster together. Evidence suggests that in most real-world networks, and in particular social networks, nodes tend to create tightly knit groups characterised by a relatively high density of ties (Holland and Leinhardt, 1971; Watts and Strogatz, 1998). In real-world networks, this likelihood tends to be greater than the average probability of a tie randomly established between two nodes (Holland and Leinhardt, 1971; Watts and Strogatz, 1998).
Two versions of this measure exist: the global an...

Any queueing people need to do, they can do on their own machine.
I asked this over at stackoverflow, but was kicked to this site instead: -
What are some websites that are really bad (at performance, design, usability etc) that you would rather not use, but are compelled to because of necessity or lack of alternatives?
Post each example as a separate answer...
