Move tools off cassini
by River Tarnell 05 May '10

05 May '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Anyone who has OSM tools running on cassini should now start moving them to the normal Toolserver and accessing the database and renderd on sql-mapnik (ptolemy). We will be repurposing cassini once all tools have moved. - river. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (HP-UX) iEYEARECAAYFAkvZ2GgACgkQIXd7fCuc5vKj/wCeMBBU2v+xnFS754tBE2UANdZU UQsAnRQQLe5hWg41RK6Y0Iqrg/Fy0ikd =koHo -----END PGP SIGNATURE-----

ptolemy renderd status
by River Tarnell 04 May '10

04 May '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I've now finished setting up renderd properly on ptolemy. This runs under the "osm" account, and is installed in $HOME/renderd/. Anyone in the osm MMT can edit the config to change or add styles. (Right now that's only me and mazder, but additional maintainers would be welcome.) Example: http://toolserver.org/tiles/osm/2/2/1 The setup is documented at <https://wiki.toolserver.org/view/Admin:OSM>. - river. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (HP-UX) iEYEARECAAYFAkvYUNMACgkQIXd7fCuc5vJTpACeMfGMyUwN66GwOqjOn3BUWBAX Ui0An1mWjya+JRVQfL1UrhHpa4vgEiyG =Ynk8 -----END PGP SIGNATURE-----

PostgreSQL tweak on cassini
by Ævar Arnfjörð Bjarmason 25 Apr '10

Cassini used to only assign 24MB of shared memory to PostgreSQL, I changed that to 128MB. We mostly seemed to be IO-bound on cassini so it looks like this has helped..

Those servers need a lot of love. People other than me have been doing some work on it recently. We're very interested in getting more people involved. Are you interested in helping in any way?

OSM Toolserver
by River Tarnell 14 Apr '10

14 Apr '10

Hi, I'm sorry about the state of the OSM Toolserver. I said I would fix it, but I didn't. However, I will finally be having a look at this tomorrow (or possibly Thursday). Before I do that, there's a couple of things I'd like to address. Firstly, PostgreSQL. On cassini, some users had either root access or access to the postgres user. I don't feel comfortable doing this on ptolemy (and it would also mean using separate database passwords, etc. just for that server). However, I can give out full (owner) access to the 'osm' database. Rather than give this to a single user, I think it makes sense to create a multi-maintainer project to handle OSM databases. An MMT[0] is a role account that multiple users have access to. The 'osm' MMT will have owner access to the osm database on ptolemy. Since this does not confer any additional privileges, and the OSM data is not private, we can easily add people to the MMT (Peter, Tim?), and these people will be responsible for ensuring the database is available. This is better than the current situation where only I have access, since I'm not particularly familiar with either OSM or the PostgreSQL extensions it uses. However, final responsibility for the OSM database (as well as software installation/changes) will still lie with me. If this sounds acceptable to everyone, I will drop the current outdated osm database on ptolemy, and create a new, empty database and the MMT. People who want access to the MMT should let me know (by replying to this mail with your TS username). Those people can then start on the process of importing the database and setting up replication. Secondly: renderd/mod_tile. I'm open to suggestions here. Currently, I plan to run renderd and mod_tile on ptolemy, which means only I will have access. However, there are quite a few portability issues with the OSM software which I've had to fix. I would appreciate it if someone with commit access to OSM's SVN repository would be able to work with me to integrate these patches, to make things easier in future. I will wait until PostgreSQL is working well before starting on rendered. Regards, River. [0] https://wiki.toolserver.org/view/Multi-maintainer_projects

Nominatim
by Maarten Dammers 07 Apr '10

07 Apr '10

Hi everyone, As you might know I uploaded 250.000 images from http://www.geograph.org.uk/ to Wikimedia Commons. Of course these images need to be categorized. For this I use reverse geocoding : I know coordinates of the location, I just need to know the name of the location. I used http://ws.geonames.org/extendedFindNearby for this (worked at that time, seems to be down at the moment). Results seem to be pretty good, but some more accurate results would be nice. Someone had already pointed out to me that I could use the reverse geocoding feature of Nominatim (http://wiki.openstreetmap.org/wiki/Nominatim) to categorize images at Commons. I just implemented it and this tool seems to catch a lot of images in the overcrowded categories. Would it be possible to set up a local copy of this tool at the OSM toolserver? Maarten
