I am wondering how to use CouchDB's map/reduce with multiple parameters. For example, if I have teams that have players with ages and genders, I assume I would do this for my map function: "function(doc){ if(doc.team_name) { emit(doc.team_name, doc); } }" However, I am unsure how to write a reduce function to get the oldest m...

Any help will be appreciated. Thanks ...

Hello and Welcome I am trying to make a 2-D tile system heavily based off of the Snake example. The original mTileGrid is still there, but there is a new array: mMapGrid. The point is to copy the data from mMapGrid to mTileGrid on each update cycle and therefore simulate an area larger than the immediate screen. I wrote more functions...
I need to create a range-graded circle proportional map, i.e., a map that has circles overlaying a map the size of which circles indicates the proportional density of what I'm trying to measure.

I have a 2D "map" of items in discrete cells (some cells having no items). Each item has a mutual "relationship" level with every other item -- the higher the relationship level, the more related they are. I ran a simple self-organizing map algorithm (each item tends to drift towards items that they are more related to), so the map is ...
I would like a library that works just like servlet mappings without the servlet container. It should support concepts such as /* maps the default value /exact maps exact path maps /prefix maps any path that begins with "/prefix" *.suffix maps any paths that end with "suffix". Imagine something like a Map that accepts str...
