The call for papers for the 1st International Conference on Software Language Engineering (SLE) is public now. I am happy that we did all the work to start this new conference. I am 100% confident in the SLE conference; it’s backed up by a strong and...

I have been talking about API migration a lot lately. I have even a draft paper in limbo ... so much in limbo that I don't even link to it here. In fact, I admit that it is very difficult to get anything done scientifically and practically on...

Greetings from POPL in Nice . J Years back, I had to convince one of my previous bosses that the attendance of an ICFP conference can be reimbursed from the department’s budget. Despite his formal background and earlier activity in the programming...

Typed XML programmer ... .. Where do you want to go tomorrow? ... What are your pains today? ... What’s your scale of typing? ... Welcome to LINQ! To be cont’d

In a comment on “ More Haskell in Java 7 or 8? ”, I get this question “How does your `Retroactive Interface Implementation’ [in JavaGI ] compare with VB9's `dynamic Interfaces?’” Very much appreciated question! At this point in time (but this might...

So C# (3.0) has lambdas, list-processing functions, some good amount of type inference … hey, who would have thought that mainstream OO programming would get so much less dysfunctional say just 2 years ago. Now Haskell is cool for many reasons other than...

Recently, I started to re-wire some mildly used parts of my brains to accommodate capabilities for a 1 st year CS course on OO programming and modeling. Long before I joined the faculty in Koblenz, the course had been designed to get students going in...

I have been somewhat silent for all kinds of boring reasons, but also quite so because I am terribly slow in grasping even basic category theory. (You don’t need to have any such knowledge to enjoy this post – just a bit of time because I guess this is...

[21 August 2008: We have been discussing language engineering over the year. The article below may be a little bit outdated by now. In any case, we prefer the term "software language engineering" (SLE) these days. This decision also has to do with the...

Most Haskell programmers have a PhD and they don’t mind overly concise notation, but there are times when the combination of Haskell features (monads, GADTs, SYB, forall, exists, rank-2, …) starts to hurt. Then it is time to switch to a more obvious notation...

Call for contributions Special issue on LANGUAGE ENGINEERING IET Software Journal (formerly known as IEE Proceedings Software) Scope The importance of metamodels, schemas, grammars and ontologies (or "language descriptions") is generally...

In January 2006 I published a first draft of “ Google's MapReduce Programming Model -- Revisited ” and I blogged about this effort some time last summer : “ Ana, cata, para, hylo, … – get it right! ”. I have finally revised the paper; in fact, it’s nearly...

I am ‘homeless’ right now, on the move between Microsoft Redmond to the University of Koblenz (at the Rhine and Mosel rivers, between Frankfurt and Bonn/Cologne), currently living in a hotel in Braga (Portugal) with 3 kids, my wife, 7 pieces of check...

My first bet in this post is that XML Schema (XSD) is here to stay for a while. I don’t even think that there is much disagreement about this matter. Regardless of the fact that I am more of a Haskell aficionado than an OO follower, I also bet (in fact...

I am surrounded by X/R and O/R mapping geeks here at Microsoft. (It’s building 35. So there are fewer X/O mapping geeks.) Some of my colleagues are close to a victory over the “ Vietnam of Computer Science ”. We have real mapping heroes around here: they...

I am crazy about language processing ! It is an excellent way to think deeply about programming , programming languages , metaprogramming , and it is the foundation of automated software engineering . Over the last 15 years or so I have written countless...

Remy notices that I am “linguistically challenged”, or perhaps he meant to say that I should account for alien (use of) English/American vocabulary by injecting more smileys so as to help with distinguishing accidental from intentional fun . I wouldn...

CALL FOR PAPERS IEEE Transactions on Software Engineering Special Issue on Software Language Engineering May-June Issue of 2009 IEEE Transactions on Software Engineering seeks original manuscripts for a Special Issue on Software Language Engineering...

The department of Computer Science, University Koblenz-Landau, Campus Koblenz invites applications for 2 research positions, available initially for 2 years: * 1 PostDoc * 1 PhD student The corresponding funding is part of the state of Rhineland...

So here is the long promised paper on the Java case study for grammar convergence . Getting all these huge Java grammars to converge was not easy. We are still learning how to do this properly. We are still working on our transformation language, but...

Here is just a quick update on the 2nd Summer School on Generative and Transformational Techniques in Software Engineering ( GTTSE 2007 ), 2 - 7 July, 2007, Braga, Portugal. See my other plug for the school that I posted a while ago. In addition to the...

I have turned a bit too much into an org animal over the last year or so: several conference organizations, special issues in journals, way too many PC member ships (in fact, there are too many workshops that are like mini conferences). Add to this that...

I enjoyed delivering an invited lecture at the PhD autumn school IPA 2008 . Abstract For about 4 years now I have been sporadically talking about API migration as a scientific and technical challenge as well as a potential business idea. It all started...

I am extremely sad that I can’t make it to ICPC 2007 in Banff this week even though I had planned for this attendance almost an entire year in advance. The simple reason is that I am relocating to Europe this week and moving between continents is all...
