Ken Robinson warns us about schools killing creativity:
Ben Goldacre is a medical doctor, author and humorous speaker who fights pseudo-science, especially in healthcare and pharma industries:
A new great tool to explore our lexical culture: the ngram viewer. Have a look to the following video first:
Discovery, at Palomar Telescope (San Diego, CA, USA), of the closest (type 1) supernova found in the past 25 years. It is “only” 21 million light-years away, in the Pinwheel Galaxy. To locate it, take the last two stars in … Continue reading
Stuxnet is a very sophisticated virus, famous for having destroyed nuclear installations in Iran. Variants are now being developed. They can attack, as Stuxnet did, so called “SCADA” (Supervisory Control And Data Acquisition) IT systems, which are used to monitor, … Continue reading
The following video, recorded in 2006, predicts somehow the H1N1 flu pandemics of 2009 and warns us about the risk of H5N1 avian flu, which is still high, according to a recent declaration of the FAO. According to Larry Brilliant, … Continue reading

PhD of University Paris VI (now UPMC Sorbonne University) Research carried out, between 1997 and 2001, at Project CODES (now SECRET) at l’INRIA, under the supervision of Pascale Charpin, Research Director at INRIA, Project CODES Director, and of Daniel Augot, … Continue reading
In this elementary and introductory talk at INRIA‘s Junior Colloquium, we present the usual problems that occur in the theory of error-correcting codes and of cryptography. We show how the use of effective algebraic geometry over finite fields can help … Continue reading
I this talk given at the 3rd European Congress of Mathematics (3ECM, Barcelona, Spain, July 2000), we illustrate how the computer algebra system MAGMA can be used for the implementation of sophisticated algorithms requiring many primitives in various branches of effective … Continue reading
This article describes an algorithmic improvement on Sudan’s algorithm for Reed-Solomon codes and its generalization to algebraic-geometric codes by Shokrollahi and Wasserman. Instead of completely factoring the interpolation polynomial over the function field of the curve, we compute fast sufficiently … Continue reading
This mini-article (in French) presents the Reed-Solomon codes and the principle of their decoding (2006).

This package contains two C programs. The first program computes a lower bound on the genus of a curve defined over a fixed finite field, given its number of points. The second one computes an upper bound on the number … Continue reading
Talk at Journées Nationales de Calcul Formel, CIRM (November 2005) We propose an algorithm to find the roots of a univariate polynomial with coefficients in the function field of an algebraic curve (or more generally, in a discretely valued field). … Continue reading
