Archive log : August 2009. An upgrade of the site was intended by putting on line a bunch of research notes, free softwares and whatever; when four hard drives containing them crashed simultaneously. Considering it was the tenth (definitive ?) loss of (precious ?) data, this and other events stopped any intellectual activity for a moment out-there, however you can visit this page from time to time, maybe things will change. Regards. July 2011.

Archive update : September 2020. A dusting-off of the thick layer of quarks dust that has covered the electrons of these web pages, over the years is begining. A recompiling of research paper notes of that past era, is also on the way : cf the linked diary log or the above table for more details.

PS : domains of visitors have also been logged with a PHP script in order to spot Human ones among the vast majority of robots. Regards.
