i'm implementing web service (no html, no templates, json) django , i'd able merge url patterns code doesn't repeat itself. this urls need supported: host/players/12/ returns player's 12 info host/players/me/ returns logged player info the 2 return same if logged player has id 12. need support more urls like: host/players/12/other-stuff/ host/players/me/other-stuff/ how avoid having 2 different view methods /other-stuff/? this have far: instance_url_patterns = patterns('', url(r'^$', instance_with_id), url(r'^other_stuff$', other_stuff_with_id), # more suff goes in here ) current_instance_url_patterns = patterns('', url(r'^$', instance_without_id), url(r'^other_stuff$', other_stuff_without_id), # more suff goes in here ) players_url_patterns = patterns('', url(r'^$', show_list), url(r'^(?p<pk>\d+)', include

what correct way implement session on g-wan's ruby, idea: send random cookie if not exists, or guid cookie fine? how read , write cookie on g-wan's ruby? documentation shows examples on c create file if not exists on /tmp/rubysessid-#{cookie_guid} php did read content on every request, , rewrite when changed but problem be: 2 requests same source on same time rewrite cookie file content @ same time making possible data corruption or inconsistency is there better way implement session on g-wan's ruby? web frameworks use databases or key-value stores (sometimes called dictionaries) keep track of sessions. i not ruby developer guess such features available. and g-wan lets access http request headers ruby (like other of 15 programming languages), there's no problem access http cookies. the "documentation shows examples in c" because g-wan written in c c scripts. there, made sense fill gap g-wan api made c/c++, etc. that gap not e

i'm using odrpack library in python fit 1d data. works quite well, have 1 question: there possibility make constraints on fitting parameters? example if have model y = * x + b , physical reasons parameter can in range (-1, 1). i've found such constraints can done in original fortran implementation of odrpack95 library, can't find how in python. of course, can implement functions such return big values, if fitting parameters out of bounds , chi squared big too, wonder if there right way that. i'm afraid older fortran-77 version of odrpack wrapped scipy.odr not incorporate constraints. odrpack95 later extension of original odrpack library predates scipy.odr wrappers, , unclear legally include in scipy. there no explicit licensing information odrpack95, general acm toms non-commercial license.
