A Short History of The Internet
THE WEB - html, http, url web page : html, javascript, css
MArch 1989, Tim Berners-Lee publishes 'information management: A proposal'. Could login to servers via physical terminals and ssh. He was working on improving terminal interactions with server environments. http://www.w3.org/History/1989/proposal.html hypertext -Ted Nelson "Computer lib / Dream Machines" defines computer lib championing creative use of technology and computers. He defines Hypermedia in his unstrcutured, loose writng format. Ted Nelson believed in central ownership and a network where users would license in a cut/copy format rather than a c opy paste format. Brings up the argument about the freedom of web2.0 where all the content is free,but access through telecomms costs. Another system would be free acess but pay for content , that way authors would get credited and payed.
HTTP protocol we no longer view the "original" html doc on the server, we request php,perl that access the html for updates , and caches the file so that it doesnt have to reload it to show it to the browser client every time.
Hosting & Databases The economics of hosting... Its only as stable as the next Bussiness plan. Which isnt wrong, its just bad for us to assume that this is unfair (that when a company changes its bussiness plan and deletes your account its not fair) If you did have an economic network where you became the purchaser or the license owner of content when you embedd, rather than being the customer, you become the buyer and therefore if the company/ server goes down than you can still have ownership.
Active archives When 1 person (or millions of people) loose their myspace or geocities page all you hear is complaints, but the scale is greater when cultral institutions and large bussiness (or their server hosting companies) sink and cant pay to recover their archives.

CGI Scripting
CGI lesson Networked prototyping cgi = Common Gateway Interface using the two simple server commands from a dir of your choice ("python -m simpleHTTPServer or python -m CGIHTTPServer")
write a hello world cgi script
- !/usr/bin/python #shebang
print "Content-type:text/html;charset=utf-8" #header print #must have blank return before body
print Hello World
or hello time
- !/usr/bin/python
print "Content-type:text/html;charset=utf-8" print import datetime now = datetime.datetime.now() print str(now)
if you point your browser to your cgi-bin/hello.cgi then you should run the clock python script successfully you must changer perms on the chmod file how to link to a cgi script and return results in your html.. project brief make a basic cgi run.... also use this line to specificy the python which you run on your local disk
- !/usr/bin/env python
Guestbook example & hitcounters make a counter textfile that updates everytime script is run. http://pzwart3.wdka.hro.nl/wiki/Python_CGI
checklist - PYthon and CGI
- 1.create a folder called cgi-bin name your python sketch with 'cgi' extension 2.add shebang line to python script
- !/usr/bin/python
- !/usr/bin/env python
Sailor's Dictionary
Sailor's Dictionary translates your words into the sailors dictionary via a speech search engine. (must use google chrome for speech enable) http://headroom.pzwart.wdka.hro.nl/~max/words2.html

q = form.getvalue("q", "").strip().lower()

Google Speech Recognition
Google have a pretty handy speech api that you can use with javascript here are some examples (must use chrome) -
