I also wonder about privacy and security in a distributed system. Will the distributed system only contain the blurred images? What about the original images, will they be spread over the world, to servers ran by unknown people, organizations, governments? Will that be an improvement over having them owned by Facebook? m. ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

The only distributed data store I'm aware of with an actual implementation is Freenet. Freenet exhibits classic long-tail behavior: popular data has high (>99%) availability with rapid transfers, while the vast majority of data objects exist only as references from other objects, and on the rare instances where they're still in the data store, transfer times are measured in minutes. If you treat a Bittorent index as a distributed data store, you see the same pattern: a few popular torrents have hundreds or thousands of seeds and download as fast as your connection can handle, while the majority have, at best, one seeder, and many only have one or two users with partial copies, hanging around in hopes that someone will eventually show up with the remaining pieces. In the context of a street-level photography system, distributed storage means that you'll have no trouble downloading images of Old Faithful or the Eiffel Tower, but you'll be lucky if you can get even one photo of Road 783 in central Nebraska. Distributed storage is one of those things that sounds good, but nobody's figured out how to make it actually work well. -- Mark ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

Re: [OSM-talk] OSM Carto not updating
Hi, short update on the issue: libosmium has just made a new release that fixes the issue: https://github.com/osmcode/libosmium/releases/tag/v2.15.6 osm2pgsql and Nominatim will get new bug-fix releases with the new libosmium version by today or tomorrow. You can already download the new libosmium and build osm2pgsql against that to get a fixed version. If that is not an option, you can get your installation unstuck for now by patching the configuration to ignore the offending Klamath forst. For openstreetmap-carto, add the following patch to your openstreetmap-carto.lua file: https://gist.github.com/lonvia/ab7db4156bbfbcf8ebe1ba8185c2e66c For Nominatim, you need to skip the relation in the import style file configured through the CONST_Import_Style variable. This would be settings/import-full.style per default. You need to add the lines as in this patch: https://git.openstreetmap.org/nominatim.git/commitdiff/f9ba2af (careful, the osm.org installation uses import-extratags.style. You must apply the patch to the style file you use. Just make sure the lines are added at the top of the file.) In both cases: after you have applied the patch, kill osm2pgsql and then restart your update process as usual. Kind regards Sarah On Sat, Jun 27, 2020 at 06:25:11PM -0400, Lynn W.
