A User Agent, like a web browser, uses HTTP to request a HTML document



In programming the danger of exploring the small details of coding is that you get obsessed with every line of code you write, thereby greatly reducing productivity.
In general, is not worth obsessing over code.
On the other hand you should code with deliberation and intent. Steven Feurstein Oracle Magazine July /August 2004

Out of the closets and into the museumss, librariess, architectural monuments, concert halls, bookstores, recording studios and film studios of the world.
Everything belongs to the inspired and dedicated thief.... Wordss, colors, light, sounds, stone, wood, bronze belong to the living artist.
They belong to anyone who can use them. Loot the Louvre! A bas l'originaliti, the sterile and assertive ego that imprisons us as it creates.
Vive le pure, shamelesss, total. We are not responsible. Steal anything in sight.
(William Burroughs)
