“Allopatric speciation” occurs when a biological species divides in two distinct populations, due either to the emergence of a natural boundary (river, mountain) or to migration in opposite directions. Over hundreds of generations, the genotypes of both populations evolve on their own until, finally, they become two separate species. For some species of fruit-flies, this […]

Babylon and the City Recipe
Up to the beginning of the 20th century, the Ancient Testament had been the most cited text in societies with Christian heritage when it came to condemning the human hybris and its emblematic spatial figure: the city. Yet, quite surprisingly, the most anti-urban text contains the perfect set of ingredients to build one. As the […]
RStudio – one big step towards user-friendliness of R
R is the greatest open source statiscal programming package around. It is all a mapper need to pretreat data. Yet it suffers from interfaces that are either uggly, tedious to set up, clumsy to use or all of these. After years of glaring at the Windows interface of R, I’ve finally sutmbled upon a nice […]
The tourist as the main inhabitant of a place
Who’s the real inhabitant of a place? For a long time, population maps have been constructed as if everybody stood still in their homes. Yet leaving this “domostatic” perspective is to geography like opening Pandora’s Box. All objects of any concern to the discipline must then be understood in a dynamic relationship to the rest […]
The Pope, Osama bin Laden and The Crucifix Map
Easter 2011 has been marked by a very particular conjunction of celebrations: the beatification of the body of the Pope John Paul II, preceded by its exhumation the capture and burial in deep sea of the body of Osama Bin Laden. John Paul II’s body has been moved to a marble stone monument in Pier […]
Paths in the green and spatial planning as a translation process
This map is an agent-based simulation result produced by NetLogo. It has been programmed years ago by a friend of mine, Alexios Kitsoupulos, from the University of Lausanne. What you see are paths produced in the green by people moving from one place to another. The basic rules are : – Individuals use existing paths […]
An autoportrait of a lived space
This is a map by which I’ve presented myself to my students on the first day in a course on tourism and mobility. I’ve given it in 2010 at the Università degli Studi di Bergamo. I wanted to make two points by showing it: What a professor teaches is deeply rooted in who he is. […]
Change the language to English/US on all slides and boxes in PowerPoint 2007 to 2016
Changing the language of a whole presentation in MS PowerPoint can be tedious. Especially when you translate your slides. You easily end up with a mix of languages on a number of slides. You notice, then, that it is not possible to select the main one: the language button (on the bottom bar) is simply […]
Augmented Reality and the Places of Dreams
Behind the illusion In Herzog’s Fitzcarraldo, Klaus Kinski with his eyes buried deep into another world stands on the shore of a river and says: Everyday life is only an illusion behind which lies the reality of dreams This is what the Jivaro Indians reportedly believe. But what Kinski’s character sees is his boat climbing […]
ScapeToad – Anamorphosis or Metamorphosis of the Base Map ?
Most 2D-maps are used to represent topographic metrics: distances and areas measured on the map (multiplied by the map scale) give traveling distances and land surfaces. In some cases, this information is irrelevant or even misleading [see an example]. As a cartographer, you may wish to use map metrics to represent other data, such as […]
