Bertrand Meyer's technology+ blog
Software engineering, programming methodology, languages, verification, general technology, publication culture, and more
Bertrand Meyer Many blogs including this one rely on the WordPress software. In previous states of the present page you may have noticed a small WordPress bug, which I find interesting. “Tags” are a nifty WordPress feature. When you post a message, you can specify one or more informative “tags”. The tags of all messages appear in the right sidebar, … Read more
In a few weeks I will be teaching again my Introductory Programming course at ETH, based for the first time on the published “Touch of Class” textbook [1]. For fun (mine if no one else’s) every lecture will conclude with a haiku summarizing the topic. I made up a few, given below, and am opening … Read more
Part of the experience of being a scientist, in the industrial age of publication, is the rejection letter; especially the damning review whose author, anonymous of course, does not appear particularly competent. I have my own treasured collection, which I will publish one day. For a fiction so artfully designed as to be almost as good as the real thing, … Read more
Last year I published in IEEE Computer a short paper entitled “Seven Principles of Software Testing” [1]. Although technical, it was an opinion piece and the points were provocative enough to cause a reader, Gerald Everett, to express strong disagreement. Robert Glass, editor of the “Point/Counterpoint” rubric of the sister publication, IEEE Software, invited both … Read more
My textbook Touch of Class: An Introduction to Programming Well Using Objects and Contracts [1] is now available from Springer Verlag [2]. I have been told of many bookstores in Europe that have it by now; for example Amazon Germany [3] offers immediate delivery. Amazon US still lists the book as not yet published [4], but … Read more
[Note: an updated version of this article (June 2011) appears in the Communications of the ACM blog.] The world of research funding, always a little strange, has of late been prey to a new craze: paradigm-shift mania. We will only fund twenty curly-haired cranky-sounding visionaries in the hope that one of them will invent relativity. The rest of … Read more
Once in a while one hits a tool that is just right. An example worth publicizing is the EasyChair system for conference management [1], which — after a first experience as reviewer — I have selected whenever I was in a position to make the choice for a new conference in recent years. At first … Read more
“For someone in search of a software development method, the problem is not to find answers; it’s to find out how good the proposed answers are. We have lots of methods — every year brings its new harvest — but the poor practitioner is left wondering why last year’s recipe is not good enough after … Read more
A spectre is haunting programming — the spectre of null-pointer dereferencing. All the programming languages of old Europe and the New World have entered into a holy alliance to make everyone’s programs brittle: Java, C, Pascal, C++, C# and yes, until recently, Eiffel. The culprit is the use of references to denote objects used in calls: … Read more
