Smart takes time to think about / time to code. You don't seem to have included any time for it in your 6 minutes. Also as you say you are well aware of osm2pgsql and mapnik, you might even say expert. So your 6 minutes is the time for an expert to make the changes - most people are not experts. Let me give you an alternate time-line at the other end of the scale: Receive and read bug report that map symbol for police no longer appears (2 min) Research why it no longer appears (20 minutes of reading wiki and mailing lists) Research on how to add emergency to the database (20 more minutes of reading the wiki) Deicide on process to fix bug (10 minute meeting between developer and server admin) Produce patch to fix issue (we'll go with your 6 min) Re-import database - this person doesn't understand osm well enough to do something 'clever' (20 min monitoring over a few days) Test (2 min) Work out why it doesn't appear (5 min - your patch is actually very slightly wrong btw, can you spot your mistake?) Test (2 min) Deploy to live server (another 20 min monitoring) Retest (2 min) Close bug (2 min) Total time: as near to 2 hours as makes no difference. Let's say the average is an hour - I think it's fair some people will do it in 10 minutes, some will will spend 2 hours trying to work out what to change and another hour on IRC asking for help! Let's say there are 100 people using mapnik / osm in the world - I'm sure it's more than that :) 1 * 100 = 100 hours just on mapnik. However the above is just for fun - lets replace my original statement with 'a lot of time' and move on... -- Brian _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
