I vaguely recall that you were no happy that serge wants to change the code because it would not be in sync with the book. Now we can co-evolve them. Every I do is open-source and freely accessible so position yourself and join effort (I do not like SciSmalltalk as a name). Now we have the possibility to make on nice library but you need to sync. > I am trying to avoid what the Python community did with NumPy and > SciPy which is a mess. > Ah you see you have to sync with Serge. I think that Serge was not aware about that you publish the code in your repository. Now we want to rename the acronym (because DHB is not good) and probably improve the code of the library while keeping the book in sync (like using String streamContents for printing). I personally hate to see all the comment with a copyright and a commit dates.

I see and appreciate your effort really, but there is no reason to hide NumericalMethods from the book announcement. I am trying to avoid what the Python community did with NumPy and SciPy which is a mess.

Re: [Pharo-users] PostGIS in Pharo

Sure, I'll collect georeferenced data in a mobile app, which I'll later have to group each one according to whether they fall inside a certain polygon (geopolitcal boundaries, like city, district, province, etc.). I could also geocode the coordinate and store all that data (city, district, province, etc.), and then just group by each of these. And then I'll have to plot that data on a choropleth map. But I'm asking to know if somebody has somehow mapped smalltalk geometry objects to the typical geometry object of PostGIS. Something like PGPoint, PGPolygon, that can "translate" themselves from/to string literals. I'm trying to avoid writing everything by hand in SQL. Regards! pd: I'm also considering using something like CartoDB for this task, which is a few levels of abstraction higher. Esteban A.
