Do we have to fight Click Fraud? (yes)

September, 28, 2009
Sylvain

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.

Converting a pdf from version 1.4 to 1.5, 1.6, etc.

September, 28, 2009
Sylvain

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 […]

Is Google selling mobile phones?

September, 23, 2009
Sylvain

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 […]

Are my decisions really mine?

September, 21, 2009
Sylvain

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 […]

Testing triangular properties (1/2)

September, 19, 2009
Sylvain

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 be the complete graph on vertices and be a set. Let be a function, and let be a real number. We […]

MapReduce?

September, 16, 2009
Sylvain

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 and a data structure (most of the time a sequence), that calls the function on each of the structure’s items and returns a list of the return values. Here is an example: […]
