Cool, I was not aware these existed. Thanks.

Good catch, I am sometimes numbers-dyslectic (well at least I got all the digits right, right?), fixed it. In my answer I did type it correctly, in my defense :)

comment deploying geoserver on linux or windows: performance implications?
Yes, I had found that already too, but it says nothing about performance, nor hard figures. If it was my choice, I would go for an ubuntu system. But to convince my client, I need a little more than a personal preference.

comment deploying geoserver on linux or windows: performance implications?
Thanks, I had already read that document, and applied some of the great advice to tune the performance of my windows servers. But in the document I do not find anything directly related to arguments preferring to choose linux over windows servers. I would rather prefer some hard data :)

comment converting oracle geometry to postgis with 3d data (wkt?)
For completeness: the sdo2geojson as in the link always created 2d data. I created my own fork here: gist.github.com/nathanvda/a61ab4b094c4c3429a39 that always generates 3d data.

comment Openlayers remove previously drawn polygon on starting to draw next one
Yes, agree with @Vadim: not very gentleman-like to just regurgitate the answer Vadim gave you, and then award yourself the answer. At least give the man some credit for helping you.

comment finding the correct transformation (from EPSG:31300 to EPSG:4326) or how to store two srid in one table
When I did the conversion starting from 31370 it transforms correctly. Thank you for the tip. Confusing though: seemingly similar srid but they are not :)

@AndreJoost: sure, please clarify what you expect exactly. A lambert 72 point converted to WGS84? Or ... ?

@msayler I was aware of this, but I thought it was not the best coordinate system to store the data in. I assumed WGS84 or ETRS89 are better. Not really sure why :)

Thanks. The weird thing remains if I render the original Lambert 72 data with geoserver, it is rendered correctly. I can verify this, because the pipeline leaves a very visible shade in the satellite imagery. If I transform the data using Postgis to wgs84 it is no longer rendered correctly. But I will try changing the coordinate systems (31300/31370), and maybe try qgis to transform it (if I get it installed on mac osx).
