Re: [OSM-dev] OSM server installation - problems with create

This is good because it becomes hard for even the stupidest programmer to create memory leaks, but on the other hand the programmer is not usually told when ruby decides to make an mmap call and what the return value of it was. Or would that be 'too easy'? ;) In a way, yes.

Re: [OSM-dev] Purpose of visible tag?

Hi, i see the visible tag being used in examples of the 0.5 api, but i don't see any explanation for it. How/when gets something invisible and how should an osm editor treat this? Are invisible items to be ignored completely? Invisible items are those that have been deleted. You only get them when you ask for an object's history and that object has been deleted, OR in a future give me all deleted objects in this bounding box call. The api map call returns them aswell - all of them set to true so basically when you use the map call they could be suppressed.
