i trying understand, monkey patch? is methods/operators overloading or delegating? does have common these things? no, it's not of things. it's dynamic replacement of attributes @ runtime. for instance, consider class has method get_data . method external lookup (on database or web api, example), , various other methods in class call it. however, in unit test, don't want depend on external data source - dynamically replace get_data method stub returns fixed data. because python classes mutable, , methods attributes of class, can as - and, in fact, can replace classes , functions in module in same way.

rails 2.3.5, ruby 1.8.7. in prior question , there number of solutions exporting data in csv format, of them seem construct data in memory before sending. wise when exporting large data sets? of solutions in prior question avoid this. or impossible avoid building response without building whole response locally, either in memory or in temp file? i not surprised if latter true, since if there error in csv generation, might want send error message instead, might generating way data want generate data in memory/on disk. you can stream directly csv library (fastercsv in ruby 1.8). render :text => proc { |response, output| csv.generate(output) |csv| csv << ... end } you should use find_in_batches if concerned memory footprint.
