Bertrand Meyer Word Umlottery [ˈʊm.lɑːɾɚɹi] (fr. umloterie, f; ger. Umlotterie, f.; it. umlotteria, f.; rus. умлотерия , f.). Definition A spur-of-the-moment and generally random decision, by a hesitant speaker of German talking in front of a (typically large) native-speaker audience, to pronounce the next intended word with, or without, an umlaut on the decisive syllable. Example use … Read more
A couple of weeks ago I proposed a small quiz. (I also stated that the answer would come “on Wednesday” — please understand any such promise as “whenever I find the time”. Sorry.) Here is the answer. The quiz was: I have a function: For 0 it yields 0. For 1 it yields 1. For … Read more
Alexander Kogtenkov pointed out to me that precursor work to my papers on the Alias Calculus [1] [2] had been published by John Whaley and Martin Rinard [3]. There are some significant differences; in particular my rules are simpler, and their work is not explicitly presented as a calculus. But many of the basic ideas … Read more
For various reasons there have been no articles in recent weeks; now we are restarting on a regular basis! A the first topic for this new season, here is a little quiz. I have a function: For 0 it yields 0. For 1 it yields 1. For 2 it yields 4. For 3 it yields … Read more
If definitions are so hard, are requirements then impossible? The trick is that we often do not need a dictionary-style definition of what things are; we only need to know what they have, in other words what are their properties and operations. This is the abstract data type approach, also known as object technology. But it is still hard to convince the stakeholders to explain what they mean.
The fundamental idea behind EIS is to support the seamless form of software development promoted and permitted by Eiffel, where all phases of a project’s lifecycle are closely linked and the code provides the ultimate reference. Since other documents are often involved, in particular a requirements document (SRS, Software Requirements Specification), it is essential to record their precise associations with elements of the software text.
On Thursday, July 5 at 15 Saint Petersburg time (7 AM New York, noon London, 13 Paris/Brussels/Zurich/Milan), the Saint Petersburg software engineering seminar presents two talks, streamed over the Internet: Firat hour: Luciano Baresi, Politecnico di Milano: A-3: A Middleware for Self-organizing Pervasive Systems Second hour: Harald Gall, University of Zurich: Software Assessment with Software … Read more
We have positions open at both the PhD and Postdoc levels at the Chair of Software Engineering at ETH Zurich, the Chair of Software Engineering. As noted in an earlier article, I recently received an Advanced Investigator Grant from the European Research Council (5 years, 2.5 million euros) on the theme “Concurrency Made Easy”; see … Read more
