how load uitabbarcontroller nib? for uiviewcontrollers this let viewcontroller = subclassofviewcontroller(nibname: "subclassofaviewcontroller", bundle: nil); but not find similar method load uitabbarcontroller nib any thoughts? thank you edit: not using storyboards if using storyboard let tabbarcontroller = [[uistoryboard storyboardwithname:@"main"bundle:null] instantiateviewcontrollerwithidentifier:@"subclassofaviewcontroller"]; where subclassofaviewcontroller identifier. else let viewcontroller = subclassofviewcontroller(nibname: "subclassofaviewcontroller", bundle: nil) this method fine. since uitabbarcontroller subclass of uiviewcontroller there no need of separate method here in subclass

i'm dealing deletion in btree in specific case m=5 - - maximum number of keys in node 4 , minimum number of keys in node 2 now when deleting in btree using defensive approach (i must use one) when approach node must guarantee has 1 key more minimum required. here problem - let's have root 1 key , 2 children 2 keys each. when approach 1 of these children have guarantee has @ least 3 keys (because m=5). i have 2 ways - borrow neighbor or borrow father , merge. can't borrow neighbor has minimum of 2 keys borrowing father , merging creates node 5 keys - , it's more maximum of allowed keys (as m=5). what should in case? more - correct way treat such situation classical b-trees constrain key counts non-root nodes lie between d , 2d d. means merging of nodes possible if underflow has already occurred , other node involved in merge has minimum occupancy. separator key pulled parent node makes key count of (d - 1) + d + 1 = 2d, maximum fits node. merging ...

what differences between hashmap , hashtable in java? which more efficient non-threaded applications? there several differences between hashmap , hashtable in java: hashtable synchronized , whereas hashmap not. makes hashmap better non-threaded applications, unsynchronized objects typically perform better synchronized ones. hashtable not allow null keys or values. hashmap allows 1 null key , number of null values. one of hashmap's subclasses linkedhashmap , in event you'd want predictable iteration order (which insertion order default), swap out hashmap linkedhashmap . wouldn't easy if using hashtable . since synchronization not issue you, i'd recommend hashmap . if synchronization becomes issue, may @ concurrenthashmap .

i looking way redirect traffic heroku application instance else when heroku/aws experiencing downtime. i envision along these lines love feedback , other ideas. app running on heroku(or wherever) returns error. request redirect fallback url (i have far set up) this url contains clone (db included) of original application. this clone can read want avoid having sync db , forth. i reasonably efficient way of keeping dbs in uptodate every 30-60 minutes or well. not sure how this. thought docker might start more dynamic deploy. goal have redundancy , not tied using heroku app resides. am missing something? reasonable implement? taking time. [update] found this . although of light, little can use because set quite ways off 1 used. heroku paas, easy & fast server setup. when application start growing big enough, suggest change iaas virtual machine example aws, google cloud platform, azure, etc.

i'm trying head around amazing list processing abilities of python (and numpy). i'm converting c code wrote python. i have text datafile first row header, , every odd row input data , every row output data. data space separated. i'm quite chuffed managed read data lists using nested list comprehensions. amazing stuff. with open('data.txt', 'r') f: # lines list of strings lines = list(f) # convert header row list of ints , info header = map(int, lines[0].split(' ')) num_samples = header[0] input_dim = header[1] output_dim = header[2] del header # bad ass list comprehensions inputs = [[float(x) x in l.split()] l in lines[1::2]] outputs = [[float(x) x in l.split()] l in lines[2::2]] del x, l, lines then want produce new list each element function of corresponding input-output pair. couldn't figure out how python specific optimizations. here in c-style python: # calculate position pos...

is there better way of checking rsvp status of user (logged in our application) vs. specific event through graph api, calling /v2.3/{user_id}/events , going through events find 1 we're interested , rsvp_status field there? what i've tried, , didn't work: /v2.3/{user_id}/events/{event_id} /v2.3/{user_id}/events?event={event_id} /v2.3/{user_id}/events?event_id={event_id} calling of them, find out if user in of rsvp groups: /v2.3/{event_id}/{attending|invited|maybe|declined|noreply}?user={user_id} also fql not solution, if wants c&p existing fql answers, because that's deprecated since api v2.0 this related answer wondering efficiency on using graph api, because pulling user's events , going through them both time , resource expensive operation ok, found answer, quite simple: /v2.3/{event_id}/invited?user={user_id} currently method will return nothing, if user not yet part of event (was never invited , never attended/maybe himsel...
