C# lambda limit with include -

i have piece of code. return folder.getallwithinclude(x => x.subfolder).take(5); this code returns 5 folder items. want limit subfolder 5 instead of limiting folder 5. have tried following return folder.getallwithinclude(x => x.subfolder.take(5)); but doesn't seem trick. i might missing proper syntax here. thank in advance! there's no method include(where expression) . if using include load records. update you can use projection problem folder.select(f => new { foldername = f.foldername, subfolders = f.subfolders.take(5) }).tolist().select(f => new folder() { foldername = f.foldername, subfolders = f.subfolders };

c++ - Is there a way to return an abstraction from a function without using new (for performance reasons) -

for example have function pet_maker() creates , returns cat or dog base pet . want call function many many times, , pet returned. traditionally new cat or dog in pet_maker() , return pointer it, new call slower doing on stack. is there neat way can think of return abstraction without having new every time function called, or there other way can create , return abstractions? using new pretty inevitable if want polymorphism. reason new works because looks free memory every time. write own operator new, could, in theory, example use pre-allocated memory chunks , fast. this article covers many aspects of might need.

android - Why esp8266 wifi connection automatically disconnecting while switch on the AC appliance? -

-
i new esp8266 device. i'm interfacing esp8266 wifi device arduino wifi , android based home automation. when switch on light time, wifi connection automatically disconnecting. why it's happening? , reason behind that? i guess switching on ac device either causes electrical interference (the spark on relay can quite bad) breaks wifi signal, or interrupts power supply esp8266, can cause wifi fail. but really need more descriptive if want helpful answer :) what exact setup, connected what, , how, how power supplies organized, etc. i wouldn't rule out software error either, can give details on software setup also? be specific on details on failure, 'wifi connection automatically disconnecting' mean, exactly? log files help.

algorithm - How to revert change of ArrayList after using List.set() JAVA -

i have arraylist of items (each item weight , profit): arraylist itemlist: [{weight: 3, profit: 10}, {weight: 15, profit: 50}, {weight: 7, profit: 25}, {weight: 6, profit: 15}, {weight: 4, profit: 10}] then have random bitstrings representing items taken given maximum weight taken 20 (capacity = 20). let's initial random bits obtain [1,1,0,0,0] means item 1 , item 2 taken give: totalweight = 3 + 15 = 18 [<= capacity] then have random bit flipped (if bit 1 -> 0, , if bit selected flip 0 -> 1). let's order flip bits [3,2,1,4,0]. so firstly, bit @ index 3 flipped , count total weight this: [1,1,0, 0 ,0] --> [1,1,0, 1 ,0] hence, new bitstring after bit[3] flip: [1,1,0,1,0]. then count total weight again: total weight of new bitstring = 3 + 15 + 6 = 24 [> capacity] so total exceeds capacity , want new bitstring assign previous bitstring before flip: [1,1,0, 1 ,0] --> return previous state: [1,1,0, 0 ,0]. after return state: [1,1,0,0,0...
