c++ - What is the difference between is_trivially_copyable and is_trivially_copy_constructible? -

when these give different answer, , when difference useful, if @ all? the former tests trivially copyable property, in few words means type memcpy -safe. a trivially copyable class class that: — has no non-trivial copy constructors (12.8), — has no non-trivial move constructors (12.8), — has no non-trivial copy assignment operators (13.5.3, 12.8), — has no non-trivial move assignment operators (13.5.3, 12.8), and — has trivial destructor (12.4). a trivial class class has trivial default constructor (12.1) , trivially copyable. [ note: in particular, trivially copyable or trivial class not have virtual functions or virtual base classes. —end note ] the latter tests presence of trivial copy constructor , incidentally requirement trivially copyable property. implies copy constructor type performs bitwise copy. a copy/move constructor class x trivial if not user-provided , if — class x has no virtual functions

Python Program to Match Lines in File -

i trying write program in python reads through .txt file , checks if line[i] == line [i+12]: print line[i] so far, have: f=open('file.txt', "r") count=0 line in f: while count < 1000: print(count) if line(count) == line(count+12): print (line(count)) count+=1 my output 1000 zeros. any appreciated. if you're trying print lines character same 1 12 characters later: for line in f: i, c in enumerate(line[:-12]): if c == line[i+12]: print(line) break if you're trying print lines same 1 12 lines later, it's simpler in need 1 loop, more complicated in have iterator of lines, not list, can't randomly access this. one simple fix that, if file small enough, make list: lines = list(f) i, line in enumerate(lines[:-12]): if line == lines[i+12]: print(line) a better fix use itertools create shifted copy of iterator (which work eithe

javascript - Moving an array element from [1] to [0] -

you'd think it'd easiest thing in world, can't find solutions don't involve complications don't need or use approaches don't understand. i have array of objects in unity, 3 positions in array. each time script run, among other things, cube in question set [1], new cube created in front of cube , set [2], , previous cube, if there one, set [0]. result of this, array should updating cubes activated player shifting down array. works fine in respects except [0] keeps returning null on debug. since cube before 1 in question set [1], first step in code change [0]/ i've been trying with; objectlist[0] = objectlist[1]; // demotes current object[1] [0]. i understand many people have been writing own functions , using splice method avoid running out of array space, don't need kind of complexity. need set object in position [1] position [0]. hope i'm not missing simple keyword in api or anything. i think you're trying remove front-mos

Merge conflict when running 'git rebase' -

i on developer branch, , try execute git rebase remote/a_remote_branch see: first, rewinding head replay work on top of it... applying: change #1 failed merge in changes. patch failed @ 0001 change #1 my question why git rebase trying apply 'change #1'? this because when git log , see 'change #1' in local branch, why git trying apply 'change #1' again when rebase? the difference between merge , rebase rebase trying make based branch on newer version of parent branch. removes of branch commits, fast-forwards the latest parent commit, , tries re-apply changes. hence re- basing . if merge makes new commit pulls in of parent changes on top of work. conflicts (if any) in merge commit rather in existing branch work.

optimization - Handling optional/empty data in MongoDB -

i remember reading somewhere mongo engine more confortable when entire structure of document in place in case of update, here question. when dealing "empty" data, example when inserting empty string, should default null , "" or not insert @ ? { _id: objectid("5192b6072fda974610000005"), description: "" } or { _id: objectid("5192b6072fda974610000005"), description: null } or { _id: objectid("5192b6072fda974610000005") } you have remember description field may or may not filled in every document (based on user input). introduction if document doesn't have value, db considers value null . suppose database following documents: { "_id" : objectid("5192d23b1698aa96f0690d96"), "a" : 1, "desc" : "" } { "_id" : objectid("5192d23f1698aa96f0690d97"), "a" : 1, "desc" : null } { "_id"
