objective c - Obj-C editor with a bad MVC pattern, how to clean this up? -

Image
i've been working on game engine in obj-c , decided build editor in obj-c. how i've done now, rid of "glue code" , follow "best practises". time being spent on "glue code" , code base getting large maintain objects depending on each other , keeping referances. typical old-school scenario :-) the view contains lot of options i.e. checkboxes, sliders & textfields. 1) when "stars" number changed 2000, action sent controller. 2) controller verifies input, numeric textfields have number formatter text input file names or other names input verified running code check if name valid. 3) number stars (2000) sent next layer, game engine scene (which has starfield object member). 4) game engine scene applies new amount of stars starfield object member. *) if number of stars changes inside of game engine scene or starfield object, call made controller updates ui textfield. how can make right , more efficient, rid of glue code

c++ - Number of swaps in a permutation -

this question has answer here: counting adjacent swaps required convert 1 permutation another 6 answers is there efficient algorithm (efficient in terms of big o notation) find number of swaps convert permutation p identity permutation i? swaps not need on adjacent elements, on elements. so example: i = {0, 1, 2, 3, 4, 5}, number of swaps 0 p = {0, 1, 5, 3, 4, 2}, number of swaps 1 (2 , 5) p = {4, 1, 3, 5, 0, 2}, number of swaps 3 (2 5, 3 5, 4 0) one idea write algorithm this: int count = 0; for(int = 0; < n; ++ i) { for(; p[i] != i; ++ count) { // permuted multiple times std::swap(p[p[i]], p[i]); // number @ hand should } } but not clear me whether guaranteed terminate or whether finds correct number of swaps. works on examples above. tried generating permutation on 5 , on 12 numbers , terminates on those. this problem arises i

c - If I malloc(1) twice in a row, why do the values differ by 32? -

-
in c, if run malloc(1) twice , print out 2 values casted uintptr_t , values differ 32. example, void * last = malloc(1); void * next = malloc(1); printf("orig %lu\n", ((uintptr_t)last)); printf("next %lu\n", ((uintptr_t)next)); prints out orig 30572560 next 30572592 malloc(size_t size) allocates size bytes, according this . expect value increase 8 when malloc 1 byte, another. why differ 32 instead? thanks! this implementation detail differ between different compilers/standard libriaries. in general, there no guarantee subsequent malloc calls return adjacent memory regions. note each memory region associated additional metadata, including not limited region size (otherwise wouldn't possible know how memory deallocate when free run). metadata put inside of allocated region, making bigger requested. there other factors influence how memory allocated - memory alignment , "hole" finding algorithm used malloc implementation, etc.

i have file contains dates , tasks in form (datetime.datetime(2014, 5, 20, 0, 0), 'laundry') (datetime.datetime(2014, 6, 1, 0, 0), 'exam ') how can display tasks due within date ( ex. due within week ) in format ? 20/05/2014: laundry thanks assuming data list of tuples this: date_list = [(datetime.datetime(2014, 5, 20, 0, 0), 'laundry'), (datetime.datetime(2014, 6, 1, 0, 0), 'exam '), (datetime.datetime(2014, 4, 20, 0, 0), 'grocery'), (datetime.datetime(2013, 5, 20, 0, 0), 'tv')] you can sorted list based on dates doing: sorted_dates = sorted(date_list, key=lambda x: str(x[1]), reverse=true) here, passing string representation of dates key sorted function translates sorting dates sorting of strings. gives you: [(datetime.datetime(2013, 5, 20, 0, 0), 'tv'), (datetime.datetime(2014, 5, 20, 0, 0), 'laundry'), (datetime.datetime(2014, 4, 20, 0, 0), 'grocery'), (datetime.datetime(2014, 6

-
i have part of websites still using old urls. essentially, want: http://hostname/app1/static/dir1 --> http://hostname/app1/static/dir2 . the static directory may contain other resources being used. i tried following getting cycle caused nginx abort: location ^~ /app1/static/ { alias /home/app1_user/app1/static/; try_files /app1/static/dir1 /app1/static/dir2; } what should instead? if understand correctly, - a file, e.g. /app1/static/file.jpg try_files in /home/app1_user/app1/dir1/file.jpg , /home/app1_user/app1/dir2/file.jpg , lastly 404 if can't found. location ~ ^/app1/static/(.*)$ { alias /home/app1_user/app1/static/; try_files dir1/$1 dir2/$1 =404; }

Square Connect API Refund Clarification -

-
if merchant issues refund, show in both refunds list , retrieve payment endpoint? there situations in may show in one, not other (such cash, check, or other tender types)? the use case external app storing / caching payments refunds need update stored payments keep accurate sales figures. if refunds show in both places, seems best way update stored payments in use case load refunds list periodically , update stored payment using retrieve payment endpoint. regardless of tender type, every refund available both list refunds endpoint , list/retrieve payment endpoints. solution sounds one, since list refunds endpoint chronological date of refund, opposed date of original payment. you can use payment_id included in returned refund objects stored copy of corresponding payment.

algorithm - Space Complexity and Modifying the Data Set -

-
what space complexity of following algorithm? given array of n 32-bit signed integers, each value positive , less 2 power of 30, negate values in array, negate values in array second time. the question arose me out of discussion in comment section here: rearrange array arr[i] becomes arr[arr[i]] o(1) space i interested in different opinions , definitions. think subtle distinctions , definitions may missing in stackoverflow discussions on subject. space complexity refers added space requirements algorithm, on , above original data set itself. in case, original data set n 32-bit signed integers, you're concerned storage above that. in case, storage is nothing, translates constant o(1) space complexity. if required create separate array (negated, negated again), o(n) since space required in proportion original data set. but, since you're doing negations in-place, that's not case.

c++ - Splitting an STL list? -

i have circular linked list looks this: 4 -> 3 -> 2 -> 5 -> 0 -> 1 -> beginning i want split list 2 segments, reverse 1 of segments, , rejoin list. this: split, o(1) operation 4 ** 3 -> 2 -> 5 ** 0 -> 1 -> beginning reverse, o(n) operation 0 ** 3 -> 2 -> 5 ** 4 -> 1 -> beginning rejoin, o(1) operation 0 -> 3 -> 2 -> 5 -> 4 -> 1 -> beginning the stl not appear have circular linked list, i'm hoping can away representing list (forward) list. this, requires: * way split lists sublists * way merge lists together merging sublists should easy using std::list::splice , , should o(1) operation. yay! however, can't find o(1) way split lists sublists. one approach use iterators, don't think works in case because sublist goes off end of list , resumes @ beginning of list. is there efficient way implement algorithm using stl? or should give , write own circular linked list library? thanks! i no
