json schemas have a required property , lists required fields in json object. example, following (simplified) schema validates call sends text message user: { "type": "object", "properties": { "userid": { "type": "string" }, "text": { "type": "string" }, }, "required": ["userid", "text"] } suppose want enable sending message multiple users, i.e. have either userid field, or array of userids (but not both or neither). there way express such condition in json schema? naturally, there ways overcome problem in case - example, userid array single element - general case interesting , useful. not elegant @ all, think can hack out allof , oneof . like: { "allof" : [ { "type" : "object", "properties" : { // base properties come here } }, ...

when @ wrote it's double. example if write 'dog' ill 'dogdog'. why? reading , writing file, filename taken command line arguments: from sys import argv script,text=argv def reading(f): print f.read() def writing(f): print f.write(line) filename=open(text) #opening file reading(filename) filename.close() filename=open(text,'w') line=raw_input() filename.write(line) writing(filename) filename.close() as said output getting double value of input giving. you getting double value because writing 2 times 1) function call def writing(f): print f.write(line) 2) writing in file using filename.write(line) use code: from sys import argv script,text=argv def reading(f): print f.read() def writing(f): print f.write(line) filename=open(text,'w') line=raw_input() writing(filename) filename.close() and no need close file 2 times, once finished read , write operations close it.

i'm writing application in android in main activity contains navigation drawer, switches between few different views (displaying data in various ways). each view fragment. my architecture of choice mvvm - have viewmodels each activity, contain logic of specific view , provide models. views responsible displaying models , handling user interaction. now, i'm wondering, whether fragments should standalone objects or not? in terms: should serve composite views consisting of visual controls , managed main activity? or should have viewmodels on own , whole logic , main activity should handle showing , hiding them? pros of fragments being standalone are: better srr (otherwise i'd have implement logic of fragments in main activity's viewmodel), simpler implementation (activity doesn't have pass models each fragment, possibly switch ing through them check, 1 active) , reusability (i can place fragments next other , work correctly). con didn't see such architect...

is there's way call save() on model in django, without waiting response db? consider async, though need less, async calls gives callback- dont need here. want - somemodel.objects.bulk_create([list of objects ]) , every 1000 objects, without line blocking code. have no use in these rows in code. i'm looking simple, package celery seems offer way more this.. as of 2016, django web framework working (for moment, if ignoring channels ) taking http request "as argument" , returns http response possible. this architecture means there no concept of asynchronous operation in framework. if want delay saving , returns response user without waiting, can: either run thread/async block (which can tedious database transactions...) ; services ironworker allows queue operations run async a.s.a.p ; celery , may bring features case better job homemade solution.

i have huge amount (1500 million) of integer pairs each 1 associated document-id. goal search documents have same pair. my first idea use hash-map ( std::map ) using pair values keys , document-ids associated values, i.e. map<pair<int,int>, unordered_set<int>> for example: document1 - pair1: (3, 9) - pair2: (5,13) document2 - pair1: (4234, 13) - pair2: (5,13) map<pair<int,int>, unordered_set<int>> hashmap hashmap[{3, 9}].insert(1) hashmap[{5, 13}].insert(1) hashmap[{4234, 13}].insert(2) hashmap[{5, 13}].insert(2) would result into key(3,9) = documents(1) key(5,13) = documents(1,2) key(4234,13) = documents(2) my problem takes huge amount of memory exceeds available 24 gb of ram. therefore need alternative performance inserts , lookups can fit memory. in theory i'm using 1500 million * 3 (pairval1, pairval2, document-id) * 4 (bytes per integer) = 18gb when overhead costs not taking account. there alternatives problem? ...
