Interesting :

Heterocera is an implementation of an associative memory system. It is inspired by the concept of a tuple space and by the work of David Gelernter (outlined in his book Mirror Worlds).

Heterocera is designed to enable easy communication in heterogeneous environments (e.g. Arduino applications and web applications). This is done by treating the memory space as a web server - where address locations are URLs. Heterocera will handle single values, rich JSON structures and files.

By reducing all interactions to HTTP GET and POST requests even simple platforms can record and retrieve data.

This is not meant to be a NoSQL system. It is designed to:

I have a pet hate - the so called "np result backfill"

This is a syndrome that occurs on websites that use text search - and in situations where your search normally would result in no results returned.

The commercial owners of sites are so afraid that you will leave their site in disgust - and will rather show you non-relevant results than no results at all.

Personally I'd rather see nothing than being presented by non-relevant stuff.

I managed to get my mongodb data (see earlier postings) to play nice with Rails3 and Google maps

By using the Cartographer gem I managed to turn the listingsdata into

and

in just a few lines of extra code.

So now I have a mongodb with listings information on a few 100.000's of companies - all displaying nicely on a set of dynamic maps.

I have been experimenting with Mongodb's geospatial searches lately - and even though the documentation is less than perfect I have at long last managed to create the necessary geo indexes and get rudimentary "near" searches working.

The first challenge was to make sure locations were in the correct format - something like this:

notice that I had to make sure the coordinates were specified as numeric.

Also note the inclusion of the _id key - this has to be the unique and persistent id for the document, otherwise mongodb will generate its own primary key - which may not be what you want to live with.
