comment Automatically generate random polygons with a given number of vertices
Not really. Just want to test how the db works with different amount of vertices. For example: will it be able to handle polygons with 100K vertices? So, not really worried about the area, or the shape

comment connecting cartodb to existing mysql database
Did you try with the SQL API: docs.cartodb.com/cartodb-platform/…. Or you may want to ask for foreign data wrapper: cartodb.com/enterprise

comment Displaying multiple records in CartoDB with common zip code
You could just enable the zip code as field to appear in the infowindow. But not sure I'm understanding what you want to do. Could you provide a link to your map?

Thanks. Looks like GRASS is going to be the solution.

comment Why can't I perform any operation over a 700MB MIF file containing 5 multipolygons? It takes forever
Yep, that's what I'm trying to do. Seems to work modifying some PostgreSQL configuration parameters. I'll answer the question to show them. Thanks!

Yes, I think something went wrong because the table looks small. But ok. Please see update. And thanks for your response!

comment ogrinfo returns a negative coordinate for extent of mif data file
Thanks! Just a question: how did you get that red polygon? I guess you used the TOWGS84 parameters and the extent coordinates.

I got write access to the table, and created the geography field. Anyway, that solution worked too. Many thanks!

comment Hot could I generate a CRS field inside the GeoJSON object created by Leaflet layer.toGeoJSON?
Thanks! You're right. For any reason, I was thinking about epsg:3857 as a not projected CRS, what obviously isn't. Those coords are 4326, of course. Silly me!

comment min function not found compiling osrm
It makes sense. I finally used a Mac OS X machine with a 64bits kernel, and it worked. So, you're probably right.

comment min function not found compiling osrm
I finally compiled OSRM in a Mac OS X machine. So, I didn't continue with this way. But I think DennisL found the problem. It makes sense.

comment Doubts about how pgRouting topology is built and how flexible it is
Yes, probably. But I think I have a better idea now, after reading the documentation and make a few tests. It seems that there's no automatic way of doing this. It's a question about how you define your data.

About the different level intersections, I think it's explained here: goo.gl/ojGmuH
