java - Integer Time Intervals -

this question more of math problem (sorry, i'm not in math). i have time represented integer for example 700 (means 7:00) 1330 (means 13:30) 2359 (means 23:59) i have starting time , ending time , want create 15 minutes intervals between them. example int start = 700; int end = 1300; i want loop on starting time increment 15 minutes , jump on 60 next hundred. example 700, 715, 730, 745, 800, 815, 830.. etc. i can create creating calendar object , parse integer simpledateformat , add time calendar, increase minutes, , parse hours , minutes integer. way long it, there should simple mathematical way perform more efficiently. if must use integers, or decided to, can create method "plusminutes", like: public int plusminutes (int time, int minutes) { int auxminutes = time % 60; auxminutes += minutes; time += 100 * (seconds / 60); time = 100 * (time / 100); // set last 2 digits 0 time += auxminutes % 60; return time; }

nsmanagedobject - What is best practice on show temporary object and update it with original object in ios? -

asking question know right way update existing contents after user adds new content. here scenario: consider app notes app, can save note in server using api the user tries add new note tapping create button. hits " save " icon save typed note now, need call api (say, addnotes api) store typed note in server i need resign " create note " page in app immediately when user see notes list page, expect typed note but per theory, update notes list view, need api response in practical, resigning of " create note " page happens first. because sending api, getting response, calling delegates, parsing content, creating responsible views/cells new item take more time resigning view controller here comes problem. smooth experience, of shows temporary object (which stored locally) when " create note " page resigns. after getting api response, update temporary object original object consider use nsmanagedobject instead of string notes app

c++ - How to call my_function before every time sprintf is called? -

sprintf api provided platform. want filter format when used. idea is: #include <stdio.h> int my_sprintf(...) { my_filter_function(...); return ::sprintf(...); } #define sprintf my_sprintf then put these code in pch. but still worrying can't cover usages, 1 in prebuilt library , not every project has pch. have other idea? thanks. it's on windows. you can't "overwrite" built-in function. furthermore, using macro replace name results in program having undefined behaviour. so, don't try change behaviour of standard library. really, way madness lies. just call my_sprintf own code , let platform did.

clojure - Why is the ^ character used in this ClojureScript snippet? -

in clojurescript re-frame todomvc application find following snippet in todomvc.views namespace. (defn todo-list [visible-todos] [:ul.todo-list (for [todo @visible-todos] ^{:key (:id todo)} [todo-item todo])]) although have read clojure chapter on metadata don't quite understand purpose of: ^{:key in snippet above. please explain. the :key react needs when have many items, can unique within group. latest version of react not need these keys. if use latest versions of reframe / reagent, try without :key metadata. this metadata equivalent placing :key within component. example have equivalent to: [todo-item {:key (:id todo)} todo] using metadata approach convenience, must in cases easier 'first key in props passed component' approach. here's more explanation .
