Introduction to axiomatic semantics






I have released for general usage the chapter on axiomatic semantics of my book Introduction to the Theory of Programming Languages. It’s old but I think it is still a good introduction to the topic. It explains: The notion of theory (with a nice — I think — example borrowed from an article by Luca … Read more

A standard plan for modern requirements






Requirements documents for software projects in industry, agile or not, typically follow a plan defined in a 1998 IEEE standard (IEEE 830-1998 [1]),  “reaffirmed” in 2009. IEEE 830 has the merit of simplicity, as it fits in 37 pages of which just a few (competently) describe basic requirements concepts and less than 10 are devoted to … Read more
