amazing photoComputing

I can remember designing a short computer program in 1967/8 in a language called Atlas Autocode. Then the program had to be compiled and converted to a set of punched cards which were sent to Manchester to be run on an Atlas mainframe computer in a pre-booked slot. The results were sent back the following day and eventually I would get see the results. Syntax was strict and the slightest typographic error rendered the whole thing meaningless.

Nowadays we can type simple programs on our own personal laptop computer, using nothing more than a word processor and run them instantly in a browser. Some errors are even forgiven, although most are still not. The scripting language used for basic web pages is known as HTML or XHTML and this is supported by style instructions known as cascading style sheets, which define how the content will look. Another script language is used to perform simple automatic actions initiated by viewers' actions and is known as javascript.

There are also programs which enable you to create images or touch up photos you have taken.

Of course, nowadays, there are programs availablewhich allow you to create a web site from a template and press a button to convert it to code and upload it to the web.

Anyone with a web site can upload pages in a matter of seconds and they are available immediately to anyone who browses the internet. Amazing.
