Summary

Historical and conceptual overview of informatics as a domain of business, science and engineering. Early history of the domain, scientific and technical development at the beginning of the last century, the rapid development during the mid-century and the even faster paved changes in the scientific-, business and technological aspects during the last decades.

Main programming paradigms (imperative, logical, functional, object-oriented) as well as paradigms in system architecture (mainframes, personal computers, client-server systems, distributed and multi-layer systems).

The birth and disappearance of technologies, companies; trends, principles, specific events.

If it all seems too easy, then:

• Read most of Paul Graham's essays.
• Read the book of Steven Raymondi (NB! difficult for beginners :-) The Art of Unix Programming
• Read through, very funny and educative book: Philip Greenspuni Guide to Web Publishing. If you feel like, find out what else Greenspun does (can read another book) and how this famous company was born and disappeared.

• Read carefully (not at all obligatory and doesn't suit beginners) and also do the exercises: Computer Systems: a programmers perspective draft version.
• Read essays by Daniel Dennett
• Try to install Gandalf,an automated theorem proving, artificial intelligence system Gandalf (Unix or Windows+cygwin) and play around with it. Try also Otter (easier, but more classic system). How, read from here and from here and from here.
