This Q&A is part of a weekly series of posts highlighting common questions encountered by technophiles and answered by users at Stack Exchange, a free, community-powered network of 100+ Q&A sites.
What did digital pioneer Alan Kay mean by, “The Internet was done so well, but the Web, in comparison, is a joke. It was done by amateurs”? When Kay speaks, programmers listen. But like anyone who puts forward an opinion, he opens himself up to being misinterpreted. EXAMPLES - mechanize-2.7.0 Documentation.

Effet Kevin Bacon : n’importe quelle page web est à 19 clics d’une autre. En théorie, n’importe quel(le) acteur ou actrice sur la planète pourrait être relié(e) à Kevin Bacon en 6 étapes ou moins.
Et en théorie, selon le physicien hongrois Albert-László Barabási, n’importe quelle page tirée au hasard sur Internet peut être reliée à n’importe quelle autre page en cliquant 19 fois ou moins. C’est ce qu’il a découvert au cours de ses recherches, qui ont été publiées dans le journal Philosophical Transactions de la Royal Society. Barabási a découvert que, même si une page web a très peu d’hyperliens vers d’autres pages, il existe un groupe de pages qui rendent possibles cette règle des 19 degrés de connexion ou moins. Ces pages sont les Kevin Bacon du web, cela va des moteurs de recherche aux agrégateurs comme Reddit ou des sites comme Gizmodo, ce sont eux qui rendent possibles cette liaison rapide entre toutes les pages.

DownThemAll! README — Documentation for crack (0.3.1) The Bastards Book of Ruby. Parsing HTML with Nokogiri. Nokogiri The Nokogiri gem is a fantastic library that serves virtually all of our HTML scraping needs.

Installing Nokogiri Unfortunately, it can be a pain to install because it has various other dependences, libxml2 among them, that may or may not have been correctly installed on your system. Follow the official Nokogiri installation guide here. Hopefully, this step is as painless as typing gem install nokogiri. For the remainder of this section, assume that the first two lines of every script are:
The Bastards Book of Ruby. Every kind of website we've dealt so far involves pages with actual direct links (sometimes known as permalinks). – will always (or should always, unless the webmaster is changing things around) refer to this page of Department of Defense contracts for 10/28/2011 . If you wanted to email someone: "Hey, check out these Oct. 28, 2011 DoD contracts," you would send them that link. However, many websites require you to fill out and submit a form. The website then directs you to a URL for a page of results.
But the page at that URL depends on parameters set by that previous form.
