What is Web: Definition and 216 Discussions

Web is a computer programming system created by Donald E. Knuth as the first implementation of what he called "literate programming": the idea that one could create software as works of literature, by embedding source code inside descriptive text, rather than the reverse (as is common practice in most programming languages), in an order that is convenient for exposition to human readers, rather than in the order demanded by the compiler.
Web consists of two secondary programs: TANGLE, which produces compilable Pascal code from the source texts, and WEAVE, which produces nicely-formatted, printable documentation using TeX.
CWEB is a version of Web for the C programming language, while noweb is a separate literate programming tool, which is inspired by Web (as reflected in the name) and which is language agnostic.
The most significant programs written in Web are TeX and Metafont. Modern TeX distributions use another program Web2C to convert Web source to C.

    Could anti-mass explain the missing anti-matter from the big bang?

    The rubber-sheet model of gravity pictures gravity as the effect of hollows in space-time due to the mass of an object. If the model included bumps in space-time as well, the effect would be to channel all the mass into the valleys between the bumps forming a network of matter across the sheet...

    Why is dark matter distributed in a web rather than falling into clumps ?

    Why is dark matter distributed in a web rather than falling into clumps ? Under the action of gravity normal matter falls into galaxies, stars, planets etc. How is it that DM doesn't do the same but instead is in web form ?

    Canadians surf web, watch YouTube, consult Wikipedia more than any other users

    Really? I would think US users use it more... http://ca.news.yahoo.com/canadians-surf-watch-youtube-consult-wikipedia-more-other-20101228-020009-784.html" continued How do they even get their data such as age demographics ? I hope they are not data-mining.
