i'm working in multi-computer environment 2 computers access same memory on 32bit pci bus. the first computer write 32bit int. *int_pointer = number; the second computer read 32bit int. number = *int_pointer; both os's / cpu's 32bit architecture. computer pci intel based. computer on pci card power pc. the case worried if write computer changing variable @ same time read computer reading it, causing invalid data read computer. i'd know if atomicity of reading / writing same position in memory preserved on multiple computers. if so, following prevent race condition: number = *int_pointer; while(*int_pointer != number) { number = *int_pointer; } i can guarantee writes occur every 16ms*, , reads occur randomly. *times drift since both computers have different timers. there isn't enough information answer definitively. if either of cpus decide cache memory @ *int_pointer , fail , code not fix race condition. assuming both cpus k...

([] () -> decltype(std::cout << "hello") { return std::cout << "hello"; }()) << ", world!"; prints hello, world! . i don't understand what's going on here. can explain me in simple terms? ([] () -> decltype(std::cout << "hello") this creates lambda (in-place function) same return type expression std::cout << "hello" has - that's std::ostream& . [] starts lambda, () empty parameter list, -> preceeds return type, , decltype(x) equivalent type of expression x. function body: { return std::cout << "hello"; } then function called... outputs "hello" , returns stream.... ()) and finally, returned stream, little more text sent... << ", world!";

i'm new ios , monotouch, , have pretty basic need - have 2 vastly different views display in same table cell depending on whether selected or not. when load app i'll present list of products in custom uitableview, rows deselected , each row showing product names in label. user taps 1 of rows , selects it, show different view more of shopping cart layout. since 2 views different have vastly different sizes. need cell (or row?) grow , shrink according natural height of whichever view being displayed. i'm using descendants of uitableviewcontroller, uitableviewsource, , uitableviewcell solution. add both versions cell's contentview, set hidden property needed when cell/row selected/deselected show right layout. works well. i'm in demo mode right now, i'm not overly worried efficiency or responsiveness, have come later. i know getheightforrow responsible sizing rows gets called once, when cell first shown. seems me need alert tableview re-poll source new size...

guys, applied big task make mvc page configurable. means: webpart in webform. 1.we can config partial view in view,make partial view enable or not,we can drag , drop partial view anywhere in container. 2.one partial view related simple mode(entity),and fields of form in partial view can configurable:enable or not , position can adjusted. now have ideas following: 1.i create model base, let other models inherit model base,model base hold metadata related fields , model itself. 2.render settings in model base hidden field throght html helper , partial view.and on client, use jquery handle layout according setting in hidden field. 3.the partial view let render only, , real logic hand on page contain partial view. think simple , extendable.right? so ideas here? think task complicate. in past, omar al zabir blog has portal website, called dropthings, maybe closed now. tried implemented things igoogle did. can see project @ codeplex . , can find ideas find of application @ ...

this question has answer here: properties , instance variables in objective-c 5 answers what's difference between putting variable inside of @interface{} declaration in header file, , putting in @property after declaration? e.g., @interface gamecentermanager : nsobject { gkinvite* pendinginvite; } @end as opposed to @interface gamecentermanager : nsobject @property (weak, nonatomic) gkinvite* pendinginvite @end declaring property generates getters , setters instance variable, according criteria within parenthesis. defining variables in brackets declares them instance variables. following links provides more info on these. http://www.cocoawithlove.com/2010/03/dynamic-ivars-solving-fragile-base.html is there difference between "instance variable" , "property" in objective-c? http://iphonedevelopment.blogspot...

suppose greedily assigning colors edges of graph g = (v,e) follows, select uncolored edge (u,v) identify colors of edges touching u , select lowest unused color. same v. assign (u,v) larger of 2 colors. a trivial way perform step 2 check colors 1,2,... until coming across 1 not used edge touching u . there faster way? just @ this . depending on yout want, can have variations of algorithms can have performance boost, wether you're looking 1 or solutions.
