I'm a beginning expert on computer applications in archaeology - especially GIS (ArcGIS, QGIS) and databases (PostgreSQL, MySQL), but I also dabble in making websites (html/css and I learn php and JavaScript).

He on GIS.SE, I'm sort of a "noob pioneer", asking stupid questions that other noobs wanted to know but are afraid to ask themselves.

comment Is there any random data generator supporting geometry in PostGIS?
If you know some minor optimization, don't be afraid to edit and improve my code (and add a note starting with "EDIT by XYZ:" explaining why and how it is better). For major optimization (or if it is better only under some conditions), post your own answer. I won't accept my own answer until question of complex line generation is properly answered, at least for sake of completeness.

@martinf: point generation would be easy anyway, and I know of ways to generate them like the one you linked. Making random polygons means most of the problem.

comment How to visualize grd files in Quantum GIS?
There are several (slightly?) different formats with .grd extension, and QGIS can open only some of these. I don't know which format exactly is on Diva GIS, but I can't open it this way, as well as the guy who asked another question on this topic.

comment File Geodatabase (*.gdb) support in QGIS?
The linked page relies on its first link ("Download the SDK from ESRI's website"), which is dead now.

comment How to handle multiple space separator in Grass?
Yes and no - the data I have are too big for ordinary editor (hundreds mega), but Vim can handle them. Well, can handle - it took half an hour to replace first two (double space) columns, and then I left for more than two hours and found Vim still working on the third column of the half-giga file. I must have done something wrong (running too much work at once, causing frequent read from/write to disc), but prospects of preprocessing much longer than running the Grass tool make me try to find some faster workaround.

comment When a tool fails, ArcGIS returns me to the tool dialog. How to change it?
2PolyGeo: I understand this is handy, but having a chance to change it somewhere in the settings would be even handier. If you are positive there's no such option now, make it an answer. I will accept it (and perhaps give you +1 for that "ArcGIS Idea" tip).
