comment Alternative approach for loading osm2pgsql data
my import is finally crawling through its relations so I think it might make it but I'm not celebrating just yet. I've never previously read of the way cache but I'm glad this explains my memory errors. The VM is hosted on a SAN with very fast disks but I'm limited to a single CPU which isn't helping. I think downloading a new PBF might be the most important change I made in this import as all the suggestions above have been tried in different iterations.

comment Alternative approach for loading osm2pgsql data
@RustProofLabs I have been looking for an updated RAM estimation - according to wiki.openstreetmap.org/wiki/Stats there are now ~3bn nodes and there is no indication of whether memory requirements scale linearly. So far I have tested both slim mode with a high cache value and non-slim mode with a lot of memory. Both failed for different reasons

comment Alternative approach for loading osm2pgsql data
@RustProofLabs osm2pgsql documentation states -C or --cache option is "Only for slim mode". Do you know if this is a mistake? osm2pgsql in verbose mode doesn't complain when this option is provided in non-slim mode.

comment osm2pgsql Ways importing very slowly in .pbf, much slower than .osm
I re-tested with the .osm format file and it's also running slow. Since the last time I imported the .osm I have updated to the latest version of osm2pgsql from a previous 0.82. I found this mailing list entry lists.openstreetmap.org/pipermail/dev/2011-November/023841.html that suggests dramatic changes in ways import performance at a certain revision. I'm now testing with the --cache option set at 2000 to see if it helps. If now I plan to downgrade osm2pgsql and re-test the pbf

comment osm2pgsql Ways importing very slowly in .pbf, much slower than .osm
memory is an obvious go-to but it doesn't explain why the .pbf is soooo much slower than the .osm - I'm going to rerun with the .osm today and see what it reports for the speed

comment osm2pgsql import fails with parse error
@JesseCrocker thanks for the tip, it seems pretty obvious now you mention it... I'm not sure why the process I'm following uses .osm instead of .pbf but it was created several years ago and maybe things were different then.

comment Is there any learning material available for GE Smallworld?
I really don't like GE's approach to Smallworld. It seems based around the idea that if you want to learn anything about the product you need to contact them. I presume the approach is intended to get large customers connected with an account manager who can then smooth-talk them into a big purchase. But if you're the person trying to decide which GIS product to pursue what would you prefer - reams of marketing speak with vague references to "delivering on business goals" or an actual hands-on trial? It makes me assume their product is terrible and they need to make it very hard to back out.

comment ArcGIS JavaScript setRequestPreCallback is partially working?
Perhaps images are not requested via XHR? The simplest way to retrieve an image is to create an <img> element and set its src attribute. If this is the case then dojo might not even be involved

Can you elaborate on "Sometimes I am able to perform operations [...] and sometimes I am not"? What happens when you are not able to perform the operation?
