i working asp.net mvc4 website , have model & view model layer. because of reasons have different names few properties in model , viewmodel model public partial class project { public string desc {get; set;} } view model public class projectviewmodel { public string description { get; set; } } now @ model layer, need use viewmodel name of property if different. thinking of creating custom attribute can have in models: public partial class project { [viewmodelpropertyname("description")] public string desc {get;set;} } and use @ model layer string.format("viewmodel property name {0}", this.desc.viewmodelpropertyname()) i want generic if there no viewmodelpropertyname attribute on property should return same property name i.e. if desc property has no attribute should return "desc" only. here tried public class viewmodelpropertynameattribute : system.attribute { #region fields string viewmodelpropertyna...

so want build map application backbone(probably using leaflet.js). have few ideas on how design this, , wondering if there common design pattern on how this. the map integrated other visualizations - example if select marker on map happen in visualization. must able conduct geo-searches on markers in map. there 2 ways thought of doing - 1.have backbone model per marker, have collection of markers, have map view works on collection. whenever collection changes, re-render map. 2.have model called mapmodel holds json, , have data function filters json (based on geosearch or something). map renders json. the advantage of 1 think easy selections, map may deal tens of thousands, hundreds of thousands of objects, feel things very slow. is there way this, or 1 of 2 ideas i've had preferable? thanks i've been working on same problem, not claim have found "common design pattern", can tell did. i created mapmodel contains info necessary make map: ins...

so have problem have been messing while in squirrel. want create goes through inside array, e.g: local array = [1, 2, 3, -1, 5, -1, 7, -1]; and -1, want use 1 of them, 1 comes first (which in case between 3 , 5). in script, when destroys object, sets objects id -1 instead of regular number, because otherwise through out errors when trying use object. don't know if i'm doing job explaining this. another example when players connect game server, have players id 0, 1, 3 , 4 connected, when next player connects id 2. thing i'm after arrays. i have tried several things, thing closest this: for(local i=1; < array.len(); i++){ if(array[i].id != -1){ count++; } else { count = i; } } but problem 1 takes last id , replaces it, have objects 0, 1, 2 , 3 if destroy 3 , create new one, no problem. if destroy either 0, 1 or 2 instead , create new 1 not take slot, instead go number 4, not work. thanks reading, out there can me this. solved:...

i have navigation bar, wich contains navigation item, contains 2 bar buttons, these created in storyboard, , wanted change 1 of buttons @ runtime, works: - (void)viewdidload { [super viewdidload]; // additional setup after loading view. uinavigationitem *thisnavbar = [self mynavigationitem]; thisnavbar.rightbarbuttonitem = nil; // works, gets removed uibarbuttonitem *insertbtn = [[uibarbuttonitem alloc] initwithbarbuttonsystemitem:uibarbuttonsystemitemedit target:self action:@selector(insertskemaitem:)]; thisnavbar.rightbarbuttonitem = insertbtn; // works, sets btn } now, in other method, called controller, not work - (void)callchildchange { ... // remove old btn uinavigationitem *thisnavbar = [self skemanavigationitem]; thisnavbar.rightbarbuttonitem = nil; // not work? } there nothing wrong method, runs fine, nav btn item not removed ? skemanavigationitem navigation item, declared in .h file links navigation item made via st...

i have program may have lengthy execution. in main module have following: import signal def run_program() ...time consuming execution... def exit_gracefully(signal, frame): ... log exiting information ... ... close open files ... sys.exit(0) if __name__ == '__main__': signal.signal(signal.sigint, exit_gracefully) run_program() this works fine, i'd possibility pause execution upon catching sigint, prompting user if quit, , resuming left off in run_program() if decide don't want quit. the way can think of doing running program in separate thread, keeping main thread waiting on , ready catch sigint. if user wants quit main thread can cleanup , kill child thread. is there simpler way? the python signal handlers not seem real signal handlers; happen after fact, in normal flow , after c handler has returned. you'd try put quit logic within signal handler. signal handler runs in main thread, block execution there too. some...

i'm trying run smirnov test in java, see if 2 sets of data come same distribution. however, getting "cannot find symbol" error. how "construct" smirnov test not error? import java.io.*; import java.util.arrays; import java.util.arraylist; import java.util.list; import java.util.regex.*; import jsc.independentsamples.smirnovtest; import jsc.*; public class test{ public static void main(string[] arg) throws exception { double[] array1 = {1.1,2.2,3.3}; double[] array2 = {1.2,2.3,3.4}; smirnovtest test = smirnovtest(array1, array2); test.getsp(); } } two possible issues, not mutually exclusive , 1 of them definitely issue. your classpath wrong. make sure jsc.jar in classpath. you need invoke constructor smirnovtest using instance creation expression requires use of keyword new . that is smirnovtest test = new smirnovtest(array1, array2); ^^^ the second definitely issue code. without using key...

i put 2 curves on 1 vpython plot. possible? i opening curve with: gd = gdisplay(x=300, y=0, width=600, height=600, title='entropy', xtitle='time', ytitle='n', foreground=color.black, background=color.red, xmax=250, xmin=0, ymax=400, ymin=0.) funct1=gcurve(color=color.white) i updating single curve inside while loop funct1.plot(pos=(bigindex,entropy)) along plotting entropy on graph, i'd plot number of particles in particular position. 1 set of axis, 2 curves. each curve undated inside loop students can see 1 curve grow other decreases. is possible? simply create gcurve object. update both curves simultanously in while loop using plot command. example: from visual import * visual.graph import * gd = gdisplay(x=300, y=0, width=600, height=600, title='entropy', xtitle='time', ytitle='n', foreground=color.black, background=color.white, xmax=250, xmin=0, ymax=400, ymin=0.) funct1=gcurve(color=color....

i using fixed thread pool of size 8 netty worker executor. tried send same curl requests again , again server. find curl requests hang after 7 or 8 times consistently. tried increase worker executor pool size 16 , able more curl requests earlier still hangs after 15 18 times. these questions: is minimum limit worker executor thread pool size internal netty? is number of netty i/o workers same worker executor thread pool size? if not how these 2 sizes related ? thanks, sudha you should use executors.newcachedthreadpool() , limit number of workers int in *channelfactory instance

precondition: 0 < k <= n method needs return number of ways k groups can formed out of n distinct items. example, there 3 ways form 2 groups out of 3 items: 1. (a) (b,c) 2. (b) (a,c) 3. (c) (a,b) , there 6 ways form 3 groups out of 4 items: 1. (a) (b,c) (d) 2. (a) (b) (c,d) 3. (a) (c) (b,d) 4. (a,b) (c) (d) 5. (b) (a,c) (d) 6. (b) (c) (a,d) so far have public static int groups (int n, int k){ if(n==k){ return n; }else if(n>1 && k==1){ return 1; }else return n*groups(n-1, k-1); } i don't know go recursive on this. see no way break down smaller subproblems because once start counting possibilities twice. appreciated. you write: i see no way break down smaller subproblems because once start counting possibilities twice. this not true. once create first group, items in first group no longer in set of candidate items , , subproblem becomes counting possible groupings of remaining items - which, ...
