ACS event [Apr. 10th, 2008|10:49 am]

I attended an ACS event yesterday evening despite being extremely tired. The speaker was Ivar Jacobson (link reference to Wikipedia)

Ivar Hjalmar Jacobson (born in Ystad, Sweden, on September 2, 1939) is a Swedish computer scientist. He got his Master of Electrical Engineering degree at Chalmers Institute of Technology in Gothenburg in 1962 and a Ph.D. at the Royal Institute of Technology in Stockholm in 1985 on a thesis on Language Constructs for Large Real Time Systems.

In 1967 he proposed the use of software components in the new generation of software controlled telephone switches Ericsson was developing. In doing this he invented sequence diagrams, and developed collaboration diagrams. He also used state transition diagrams to describe the message flows between components.

Jacobson saw a need for blueprints for software development. He was one of the original developers of SDL (Specification and Description Language). In 1967, SDL became a standard in the telecoms industry.


This was a very well attended event and it was "informative" even though I'm not involved (nor likely to get involved) in the forms of software procedures and processes he was speaking about. He mentioned that he writes books but as with most books nobody reads them - which he argued is fine by people (such as himself) who like to write books.

I haven't seen an ACS event as popular as this since a speaker spoke on the (then) topical subect of patterns (link)
