May 08Statement Considered Harmful
I harbor no illusion about the effectiveness of airing this particular pet peeve; complaining about it has about the same chance of success as protesting against split infinitives or music in restaurants. Still, it is worth mentioning that the widespread use of the word “statement” to denote a programming language element, such as an assignment, that […]
Mar 24“Object Success” now available
A full, free online version of Object Success (1995) I am continuing the process of releasing some of my earlier books. Already available: Introduction to the Theory of Programming Languages (see here) and Object-Oriented Software Construction, 2nd edition (see here). The latest addition is Object Success, a book that introduced object technology to managers […]

We are pleased to announce the availability of EiffelStudio 22.12.
2022, Dec 12Logical beats sequential
Often, “we do this and then we do that” is just a lazy way of stating “to do that, we must have achieved this.” The second form is more general than the first, since there may be many things you can “do” to achieve a certain condition. The extra generality is welcome for software requirements, […]
2022, Oct 29New paper: optimization of test cases generated from failed proofs
Li Huang (PhD student at SIT) will be presenting at an ISSRE workshop the paper Improving Counterexample Quality from Failed Program Verification, written with Manuel Oriol and me. One can find the text on arXiv here. (I will update this reference with the official publication link when I have it.) The result being presented is […]

2022, Oct 28New book: the Requirements Handbook
I am happy to announce the publication of the Handbook of Requirements and Business Analysis (Springer, 2022). It is the result of many years of thinking about requirements and how to do them right, taking advantage of modern principles of software engineering. While programming, languages, design techniques, process models and other software engineering disciplines have […]
2022, Sep 28Introduction to the Theory of Programming Languages: full book now freely available
Short version: the full text of my Introduction to the Theory of Programming Languages book (second printing, 1991) is now available. This page has more details including the table of chapters, and a link to the PDF (3.3MB, 448 + xvi pages). The book is a survey of methods for language description, particularly semantics (operational, […]

2021, Mar 03Tomorrow (Thursday) noon EDT: ACM talk on requirements
In the software engineering family requirements engineering is in my experience the poor cousin, lagging behind the progress of other parts (such as design). I have been devoting attention to the topic in recent months and am completing a book on the topic. Tomorrow (Thursday), I will be covering some of the material in a […]

2021, Feb 26Some contributions
Science progresses through people taking advantage of others’ insights and inventions. One of the conditions that makes the game possible is that you acknowledge what you take. For the originator, it is rewarding to see one’s ideas reused, but frustrating when that happens without acknowledgment, especially when you are yourself punctilious about citing your own […]
