say there's class contains 2 different properties such as: @interface myclass : nsobject @property id valuewhenno; @property id valuewhenyes; @end while using class boolean value called 'state', know can property according 'state' by: myclass *myclass; id value = state ? myclass.valuewhenyes : myclass.valuewhenno; but found using lot of conditional statement in complex code can make readability of hard. since intend give no information 'state' 'myclass', there cannot additional boolean property in 'myclass'. is there way in objective-c class can used property conditionally short line of code such following? id value = myclass.valuebystate; have 2 instances of class 1 property instead of 1 instance 2 properties. then, when state changes switch instance instead of having code everywhere check state.

for example: struct foo { mypoolalloc<char> pool; std::vector<int , mypoolalloc<char>> vec_int; // wrapper allocator replace mypoolalloc<> here. std::vector<std::function<void()> , mypoolalloc<char>> vec_funcs; // wrapper allocator replace mypoolalloc<> here. foo() : vec_int(pool) , vec_funcs(pool) {} // want store lambdas captured variables using custom allocator well: template<typename func> void emplace_back(const func& func) { vec_funcs.emplace_back(std::allocator_arg , pool , func); } }; in above code, want allocations (besides pool itself) pull same pool object. best way writing wrapper allocator stores reference actual stateful allocator object? , pass following constructors (example): : vec_int ((mywrapperalloc<char>(pool))); is there cleaner way writing whole wrapper class mypoolalloc<> ? the standard "allocator" concept have been bett...

is there way improve running time program? time limit exceed error online judge, , seems program running slow? so, question program: http://www.spoj.com/problems/prime1/ my code (language c): #include <stdio.h> void findprime (int m, int n) { int i, prime = 1; if (m <= n) { (i = m - 1; > 1; i--) { if (m % == 0) { prime = 0; break; } } if (prime == 1 && m != 1) printf ("%d\n", m); findprime (m + 1, n); } } int main () { int num1, num2, i, cases; scanf ("%d", &cases); while (cases != 0) { scanf ("%d %d", &num1, &num2); findprime (num1, num2); printf ("\n"); cases--; } return 0; } to solve question need learn "sieve of eratosthenes" . first, idea of how works here . but, not enough solve questio...

i cannot provide code because abstract problem facing. i working on program allows user track players games. program stores players profile information in arraylist. 1 feature of program let user able browse through entire arraylist of players. let's have arraylist of player objects , size large, 1000 . possible in java allow user scroll through arraylist? thought creating 10 jlabels , each time user clicked button iterate through arraylist next 10 player objects. not seem practical. are there swing features can utilize problem? try using jtable, in each table row contains information each player. can extend class abstracttablemodel define fields per player, , player gets displayed on table row. i've written java app uses jtables more 2000 rows, , 15 20 columns, , had no performance issues. limit displayed rows, can use rowfilter, , can customise sorting using rowsorter.

i have searched on site how wait until ajax function done , found solution: function next() { $.when(checksign()).done(function () { if (uf == 1) { $("#usrdiv").css("display", "none"); $("#pswdiv").css("display", "inline"); } }); } function checksign() { $.ajax({ url: "checkuser.php", data: { user: u }, method: "post" }).done(...); } but still not working, doesn't wait ajax done direcly executes function inside done() that's because checksign doesn't return promise need chain on done function. you don't need $.when wrapper 1 single promise either function next() { checksign().done(function(data) { if (uf == 1) { $("#usrdiv").css("display", "none"); $("#pswdiv").css("display", "in...

i want control every single process system use. (and learn 1 one) use openbox, i'm confused how control startup programs , services. i have need (minimum system) in single place. executed ? in order ? "/etc/xdg/autostart/" "/usr/lib/x86_64-linux-gnu/openbox-autostart" ".config/openbox/autostart.sh" "/etc/init.d/" "/etc/rc3.d/" ... ??? you can check using below mentioned commands. ps - list processes running on system kill - send signal 1 or more processes (usually "kill" process) jobs - alternate way of listing own processes bg - put process in background fg - put process in forground
