Electronic Commerce (EC for short) is one of these conferences that mix algorithmic together with business oriented problems (bidding strategies for instance). The call for for EC 2010 is out, you can find it here. Here is a copy… PAPER SUBMISSION The conference is soliciting full papers (as well as workshop and tutorial proposals; see below) on all aspects of electronic commerce. Submitted papers will be evaluated on significance, originality, technical quality, and exposition. They should clearly establish the research contribution, its relevance to electronic commerce, and its relation to prior research. Submissions to be considered for publication in the […]

I don’t know about you, but there are several blogs that I like to read to keep abreast of web/SEO/etc developments.  Amongst these, there is one that shouldn’t be missed: it is Stanford’s CS department blog. It has many assets: it is a blog written by a star team of researchers specialising in website algorithmics, and from which most Google, Yahoo (and others) brains emerge.  In short, their postings are always interesting and there’s no « useless-post-about-a-boring-life »… All this to say that, a few months ago, Bobji Mungamuru posted about a very interesting article in which he discusses about Click Fraud.

Sometimes writing a paper can be a real pain in the neck, but the worst is when it is a pain to actually submit a paper. Sometimes conference management systems are really strict. This is for instance the case of EDAS. If you submit a paper using EDAS, maybe you will read this: The PDF file uses PDF version 1.4, however only 1.5, 1.6, 1.7 is allowed. it means that you hve to convert your PDF file to a more recent version of PDF. It took me half an hour to find a way to do that, so here is […]

Here in France, we had this morning a funny surprise during our first request to Google France. Indeed, the homepage presents this small sentence under the search box « Nouveau! Le téléphone HTC Magic est disponible. En savoir Plus ». This litterally means  « New! The telephone HTC Magic is available. To know more about it « , with a link to this this page of google.fr. On the target page, a cool picture of the HTC Magic Android, and 2 links to a SFR (the third  French mobile phone company – 19 million clients, including over 3 million using 3G technology, according to […]

At first PPC is more interesting, then SEO becomes the solution after a while. At least that’s what this nice infographic from elliance is saying.

For more information, you should go on the conference website. It’s in Australia, a very nice venue! Tremendous advances in processing, communication and systems/middleware technologies are leading to new paradigms and platforms for computing, ranging from computing Clusters to widely distributed Grid and emerging Clouds. CCGrid is a series of very successful conferences, sponsored by the IEEE Computer Society Technical Committee on Scalable Computing (TCSC) and ACM, with the overarching goal of bringing together international researchers, developers, and users and to provide an international forum to present leading research activities and results on a broad range of topics related to […]

According to Wikipedia, Social Psychology : « is a type of social science that is concerned with individuals’ thoughts, feelings and behaviour as they affect or are affected by other individuals… » and which « studies the interactions between individuals in a group, a society or in different organisations ».  How true is that definition? I’m not sure, but what I do understand is that when I read texts about social psychology they give us the key to understanding what motivates us to undertake specific actions. At this stage you should understand what I’m aiming at: how do we get people to do what […]

A few years ago, I worked together with Yves Verhoeven on the problem of testing triangular properties. We did some proofs, wrote a few pages but decided not to publish our work (since it is far from being optimal, and also far from being really interesting). However I think that this is worth a few lines in this blog. It is clearly more technical than the average post of my blog, so don’t force yourself into reading it. Let $latex K_n=(V,E)$ be the complete graph on $latex n$ vertices and $latex S$ be a set. Let $latex \phi:V\times V\rightarrow S$ […]

I was talking recently to three excellent engineers from Yahoo, Google and Microsoft this week, and that reminded me that I meant to do this post a little while ago. So I’ll keep this post short and sweet: if you’re an excellent Yahoo or Google or Microsoft engineer with solid experience in everything, I am hiring. If you want to apply for a Research Engineer position  in the beautiful town of Orsay (France), use my e-mail and we won’t need recruiters to discuss. Thanks! The beginning of this post remind you of something? yes, sure, it’s a pastiche of this […]

A friend recently asked me to explain her the concept behind MapReduce. The last time we saw each other, I had no time to do that, so I now use my  blog for this purpose. Map and reduce are particular functions that can be found we in numerous functional languages (such as python, ocaml, etc.). Map is a function that takes as input an other function, let’s say $latex f$ and a data structure (most of the time a sequence), that calls the function $latex f$ on each of the structure’s items and returns a list of the return values.
