Defining and classifying requirements (new publication)
Software engineering has improved a lot in the past couple of decades, but there remains an area where the old doomsday style of starting a software engineering paper (software crisis, everything is rotten…) still fits: requirements engineering. Just see the chasm between textbook advice and the practice of most projects. I have written on requirements … Read more
What happened to the kilogram? Schaffhausen, 16 December
December 16 (next Monday), the newly created Schaffhausen Institute of Technology organizes an entire day of events around three (no less) talks by the physics Nobel prize winner and MIT professor Wolfgang Ketterle. The culmination of the day is a talk by Prof. Ketterle in the evening on “What happened to the kilogram?”. From the … Read more
A theorem of software engineering
Some of the folk wisdom going around in software engineering, often cluessly repeated for decades, is just wrong. It can be particularly damaging when it affects key aspects of software development and is contradicted by solid scientific evidence. The present discussion covers a question that meets both of these conditions: whether it makes sense to … Read more
Ten traits of exceptional innovators
Imagine having had coffee, over the years, with each of Euclid, Galileo, Descartes, Marie Curie, Newton, Einstein, Lise Leitner, Planck and de Broglie. For a computer scientist, if we set aside the founding generation (the Turings and von Neumanns), the equivalent is possible. I have had the privilege of meeting and in some cases closely … Read more
The end of software engineering and the last methodologist
(Reposted from the CACM blog [*].) Software engineering was never a popular subject. It started out as “programming methodology”, evoking the image of bearded middle-aged men telling you with a Dutch, Swiss-German or Oxford accent to repent and mend your ways. Consumed (to paraphrase Mark Twain) by the haunting fear that someone, somewhere, might actually … Read more
Before I start screaming once again…
… at my would-be coauthors, would someone please tell them, and every non-native-English-speaker-but-aspiring-English-author, to read this? Please, please, please, please, please. In English the verb “allow” cannot take an infinitive as a complement. Ever. You may not write “my method allows to improve productivity” (even if it’s true, which it probably isn’t, but never mind). … Read more
Blockchains, bitcoin and distributed trust: LASER school lineup complete
The full lineup of speakers at the 2018 LASER summer school on Software for Blockchains, Bitcoin and Distributed Trust is now ready, with the announcement of a new speaker, Primavera De Filippi from CNRS and Harvard on social and legal aspects. The other speakers are Christian Cachin (IBM), Maurice Herlihy (Brown), Christoph Jentzsch (slock.it), me, … Read more
Small and big pleasures
(Reproduced from my CACM blog.) One of the small pleasures of life is to win a technical argument with a graduate student. You feel good, as well you should. It is only human to be want to be right. Besides, if you ended up being wrong all or most of the time, you should start … Read more
LASER summer school on software for robotics: last call for registration
Much of the progress in robotics is due to software advances, and software issues remain at the heart of the formidable challenges that remain. The 2017 LASER summer school, held in September in Elba, brings together some of the most prestigious international experts in the area. The LASER school has established itself as one of … Read more
