i getting cells uicollectionview calling dequeuereusablecellwithreuseidentifier: . want set specific configuration information first time cell returned method , not subsequently when gets reused. there hook somewhere can run "one time" code on collection view cells? obviously set information every time or use boolean keep track of whether or not cell has been initialized, i'd know if there's cleaner way first. this easy enough within cell's implementation there's no convenient way data source differentiate newly created vs reused cells. if configuration must supplied data source data source need check if cell has been configured already. the cells created once can use init or awakefromnib set initial state. cells have prepareforreuse called when being reused allowing perform changes need make per-use.

i wondering if can remove timezone date using javascript? datetime on json format want set returns more info of want/need. what have is: var d = new date(); d.settime(1432851021000); document.write(d); and output this: thu may 28 2015 16:10:21 gmt-0600 (cst) id show until hour, , moreve gmt-0600 (cst). i know javascript takes depending on current user's timezone, problem, because information saved on different countries. i trying avoid create format using like: d.date() + "/" + d.month()...etc is there better solution this? i believe d.todatestring() output format you're looking for. var d = new date(); d.settime(1432851021000); d.todatestring(); // outputs "thu may 28 2015" d.togmtstring(); //outputs "thu, 28 may 2015 22:10:21 gmt" or d.tolocalestring() "5/28/2015, 6:10:21 pm" there lots of methods available date()

i'm looking @ rails actioncontroller , curious meaning behind 'metal' folder is? why name 'metal'? i know ember has ember-metal module , i'm sure there other programming use cases it. is there convention naming 'metal'? actionpack/lib/action_controller/metal/conditional_get.rb from this article written david heinemeier hansson think of rails metal subset of middleware intended application-specific end points need speed (“write metal”, hence name).

code: file *fp = fopen(filename, "r"); if (!fp) { fprintf(stderr, "failed open file\n"); // fclose(fp) <-- should close file here? exit(1); } // operations on file. fclose(fp); question: if fopen() fails open file, should still call fclose() ? no, don't need call fclose() inside if block. once fopen() fails, retruns null need not closed . to elaborate, if fopen() success, return file * . needs closed. fwiw, returned pointer in case, of whatever value , gurantees compare unequal null. in other words, if fopen() success, returned pointer fail if(!fp) check. in error scenario (when file cannot opned some reason), null retrurned. null return value means, file not opened. don't close not opened. simple.

i have big homework assignment , got unexpected results, traced down following code for (int = 0; < 4; i++) cout << (int)((7163 / (int) pow (10, 4 - - 1))) % 10; to 7263 appears on screen, instead of 7163! not happen every 4 digit number , leaves me confused, there wrong logic or compiler's gone nuts. ideas how fix it? the problem here not compiler, rather standard library implementation of pow function. but not advisable use (int)(pow(n, k)) compute n k 2 integers. pow not guaranteed produce exact answer; may out small amount. (actually, accuracy not guaranteed @ all, implementations try not wrong more value of low order bit of result.) since casting (int) truncates rather rounds, tiny error can result in result being off 1. , in case, if result of pow(10,2) ends being 99.999999999999, converting int make 99, , 7163/99 72. so if insist on using pow , need ensure result rounded rather truncated (see round standard library function). bett...

the python multiprocessing module has class reentrant/recursive locks: from multiprocessing import rlock l = rlock() l.acquire() l.acquire() l.release() l.release() this works great processes forked common parent process and, hence, can share same rlock object. however, situations independent processes (example: web server + cron job), 1 need named lock. unfortunately, rlock() not accept name argument lock. there solution allows this? l = rlock('mylock') l.acquire() l.release() check out oslo_concurrency.lockutils . has lock context manager , synchronized decorator, both of take name , other handy interprocess-friendly parameters.

there table 2 columns books , readers of these books, books , readers book , reader ids, respectively : books readers 1: 1 30 2: 2 10 3: 3 20 4: 1 20 5: 1 10 6: 2 30 record book = 1, reader = 30 means book id = 1 read user id = 30 . each book pair need count number of readers read both of these books, algorithm: for each book each reader of book each other_book in books of reader increment common_reader_count ((book, other_book), cnt) the advantage of using algorithm requires small number of operations compared counting book combinations two. to implement above algorithm organize data in 2 groups : 1) keyed book, rdd containing readers of each book , 2) keyed reader, rdd containing books read each reader, such in following program: import org.apache.spark.sparkconf import org.apache.spark.sparkcontext import org.apache.spark.sparkcontext._ import org.apache.log4j.logger import org.apache.log...

simple question. sonarqube has duplicate code scanner. examine comment blocks in algorithm? if have 1000 source files same copyright header, detect these duplicated code? from sonarqube documentation on duplications : sonarqube allows detect "type 2" duplications means : structurally/syntactically identical fragments except variations in literals , comments. so copyright header not counted duplication.

inspired this question . we can initialize char pointer string literal: char *p = "ab"; and fine. 1 think equivalent following: char *p = {'a', 'b', '\0'}; but apparently not case. , not because string literals stored in read-only memory, appears through string literal has type of char array, , initializer {...} has type of char array, 2 declarations handled differently, compiler giving warning: warning: excess elements in scalar initializer in second case. explanation of such behavior? update: moreover, in latter case pointer p have value of 0x61 (the value of first array element 'a' ) instead of memory location, such compiler, warned, taking first element of initializer , assigning p . i think you're confused because char *p = "ab"; , char p[] = "ab"; have similar semantics, different meanings. i believe latter case ( char p[] = "ab"; ) best regarded short-hand not...

i have little question regarding python logging module. i have simple logger logger=basicconfig() how access same logger using getlogger()? or getlogger() give me logging object can access? if how access same logger in program? apologies if wrong place ask this. the python logging.getlogger(name) returns same logger object name within process. the python best practice of using of loggers each python module defines own logger @ beginning of .py file.: import logging logger = logging.getlogger(__name__) # logger def foobar(): logger.debug("in foobar") this allows later turn on , off , adjust levels of individual loggers using python's logging configuration. generally, not want share logger across modules unless have specific use case.

there numerous information static checking of contract.forall has limited or no support. i did lot of experimenting , found it can work with : contract.forall(items, => != null) contract.forall(items, p) p of type predicate<t> it cannot work with: field access property access method group (i think delegate allocated here anyway) instance method call my questions are: what other types of code forall can work with? does code contracts undertand after contract.forall(items, => != null) proven, when taking 1 item list later in code (i.e. indexing), item not null? here full test code: public sealed class test { public bool field; public static predicate<test> predicate; [pure] public bool property { { return field; } } [pure] public static bool method(test t) { return t.field; } [pure] public bool instancemethod() { return field; } public static...

i have short question runtime of while loop. have given code: calculate(int n) = n while(i > 0) = i/2 if n power of two, how while loop executed. doing revision on did @ beginning of semester , know it's not hard don't know how answer. example if n = 1, loop executed 1 time, if n = 2, loop executed 2 times, if n = 4, loop executed 3 times , on not sure how formulate mathematically. a mathematical formula use binary logarithm : log2(n) + 1

when creating foreign key constraint in postgresql from pgadmin (1.12.2 in case), following option checked: auto fk index i know if it's right leave checked time, , understand how overhead works. for instance, following constraint: alter table "user" add constraint fk_user_region foreign key (intregionid) references region (intid) match simple on update no action on delete no action; creates following index: create index fki_user_region on "user" using btree (intregionid); note creates index only when creating constraint from pgadmin . there not documentation pgadmin, , nothing option. thank you.
