i'd minimize synchronization , write lock-free code when possible in project of mine. when absolutely necessary i'd love substitute light-weight spinlocks built atomic operations pthread , win32 mutex locks. understanding these system calls underneath , cause context switch (which may unnecessary quick critical sections spinning few times preferable). the atomic operations i'm referring documented here: http://gcc.gnu.org/onlinedocs/gcc-4.4.1/gcc/atomic-builtins.html here example illustrate i'm talking about. imagine rb-tree multiple readers , writers possible. rbtree::exists() read-only , thread safe, rbtree::insert() require exclusive access single writer (and no readers) safe. code: class intsettest { private: unsigned short lock; rbtree<int>* myset; public: // ... void add_number(int n) { // aquire once locked==false (atomic) while (__sync_bool_compare_and_swap(&lock, 0, 0xffff) == false); // perform...

we made quit big ios application 2000+ objective c classes. wondering there best practice guide port android ? looking @ visual paradigm (uml) reverse engineers objective c files uml. enterprise architect allows me generate code(headers + declaration) popular language java or c++. there other approaches yet ? also, our app heavily using uinavigation , uiview controllers, wondering there similar model , implementation on android. thanks far, guenter in honesty, think planing going make crappy code insanely hard maintain. realize sounds lot of work, gonna easier in long run, "port" concept of app android , write ground up.

how can request retry on nsurlconnection? in connectiondidfinishloading method possible store , later retry connection? i looked @ [connection start], did not seem anything. connection object still contain original request? thanks it's not stated explicitly, still documentation suggests nsurlconnection instance isn't intended reused: nsurlconnection retains delegate when initialized. releases delegate when connection finishes loading, fails, or canceled. if delegate released, there's no point in reanimating connection object.

i have 3 javascript functions: validateclk() , validateampm() , getclks() and on 2 occurring events, executed follows: onchange - executes validateclk() , validateampm() onclick - executes getclks() ( getclks() returns boolean value) all 3 functions run correctly, problem is, after getclks() has finished execution , returns boolean, next function postclocks() doesn't run. i'm sure code postclocks() correct well. if don't use return statement getclks() getclks() function doesn't work expected. please :( <script type='text/javascript'> function validateclk() { .... var clks = clocks.value; if (clks == "") { alert('enter time'); } else { ... } } </script> <script type='...'> function validateampm() { ... var ampm= ap.value; if (ampm=="") { alert('enter or pm'); } ...

i know lua gc-ed. know lua can deal c objects via userdata. here question: there anyway register function it's called when c userdata object gc-ed lua? [basically destructor]. thanks! yes, there metamethod called __gc purpose. see chapter 29 - managing resources of programming in lua (pil) more details. the following snippet creates metatable , registers __gc metamethod callback: lual_newmetatable(l, "someclass"); lua_pushcfunction(l, some_class_gc_callback); lua_setfield(l, -2, "__gc");

say have combobox , so: <combobox iseditable="true" height="30"> <comboboxitem>robot</comboboxitem> <comboboxitem>robot</comboboxitem> </combobox> if user comes along , starts typing lower-case r combobox when empty, combobox predictably auto-fills word robot . great. now same user comes along , starts typing upper-case r combobox when again empty. unpredictable, combobox auto-fills lower-case word robot . not great. desperately want auto-fill robot , wpf not seem want smile down upon me. no matter (caps lock, shift+key), combobox auto-fill lower case robot , provided lower case robot precedes upper case robot in combobox's items collection. is there way prevent this? behavior maddening , makes absolutely abysmal user experience. in .net 4 can set istextsearchcasesensitive=true on combobox (or indeed itemscontrol)

i have data array contains information people , projects such: person_id | project_id | action | time -------------------------------------- 1 | 1 | w | 1 1 | 2 | w | 2 1 | 3 | w | 2 1 | 3 | r | 3 1 | 3 | w | 4 1 | 4 | w | 4 2 | 2 | r | 2 2 | 2 | w | 3 i'd augment data couple of more fields called "first_time" , "first_time_project" collectively identify first time action person seen , first time developer saw action on project. in end, data should this: person_id | project_id | action | time | first_time | first_time_project ------------------------------------------------------------------------ 1 | 1 | w | 1 | 1 | 1 1 | 2 | w | 2 | 1 | 2 1 | ...

if have function api expects 14 digit input , returns 6 digit output. define input const char *. correct , safe thing do? why not want char * seems more prudent use const char * in case since api providing. different input values generate 6 digit codes. when const char *c telling compiler not making changes data c points to. practice if not directly modifying input data.

i have array (below) var img_name = new array("images/test.jpg", "images/test.jpg"); var imgtotal = img_name.length; var rnd_no = math.floor(imgtotal*math.random()); var ojimg = img_name[rnd_no]; what need pass piece of information , attach body tag. so. if test1.jpg loaded need pass "light" body tag , if other image selected need pass "dark". alows user in cms select light or dark theme depending on image. image output randomly. how nested arrays: var img_name = [["images/test1.jpg", "light"], ["images/test2.jpg", "dark"]]]; var imgtotal = img_name.length; var rnd_no = math.floor(imgtotal*math.random()); var ojimg = img_name[rnd_no][0]; var cssclass = img_name[rnd_no][1];
