i have application uses jquery transition/fade/animate elements within ui (ie panel slide out side when toggled visible). give user option toggle of 'effects' via checkbox, depending on how set workflow of application. so instead of hidden state > effect/transition > visible state hidden state > visible state based on whether transitions enabled (most via checkbox). is possible without rewriting of hidden/visible states based on checkbox? there form of select-all remove effect? you can globally turn off jquery animations changing value of: jquery.fx.off as in: // disable jquery animations jump end state jquery.fx.off = true; jquery doc here .

i have simple blog engine using rails , mongoid orm. i have 2 models in blog, 'article' , 'url'. article model contains of post content, , url class generator function takes slug of article , creates short url it. e.g. my-sample-blog-post -> ai3n etc. etc. the problem having problems linking two. can't embed url class in article class either. my question is, can generate short url on fly, post created, inside article model? article model uses mongoid::slug give me nice post slugs, need short urls each post. any on appreciated. i think use after create callback generate short url , store in field inside article model. something this: class article field :title slug :title field :short_url after_create :generate_short_url def generate_short_url self.short_url = shorten_it(self.slug) # assuming implement shorten_it self.save end end

i use windows api createprocess function. in msdn manual it, have found if function succeeds, sure call closehandle function close hprocess , hthread handles when finished them. otherwise, when child process exits, system cannot clean process structures child process because parent process still has open handles child process. so should this? the situation process started , there no track of life. force me make thread, process created , thread wait using, example waitforsingleobject , until process dead, handles released? you don't have wait child process finish, have closehandle when you no longer need handle. the reason may want keep handle process after process has finished. may want check return status, example. long have handle it, windows can't clean after it. but if don't care anymore child does, close handle , move on. if care, call waitforsingleobject , give handle got createprocess . or call registerwaitforsingleobject (again p...

i having trouble understanding how & operator works , importance. i found example online: #include <stdio.h> void main() { int = 10; printf("\nvalue of n : %d" ,n); printf("\nvalue of &n : %u", &n); } output : value of n : 10 value of &n : 1002 firstly, why &n print out 2 numbers? secondly, why important? n variable. represents value. &n reference n. represents address in memory n store. as why important: when pass array in c, function expecting pointer. (ie: int* opposed int). if pass 'n' function, complain when compiling because types don't match (n=int, function expects int*). if pass in &n, passing in address 'n' function expects.

i've got several questions pagination. can pagination forced? can pagination controlled (eg request pages of 200 records)? if answers 1 & 2 no, threshold when pagination happens? is pagination stable (same number of records on same entity either paginated or not paginated)? thanks, vlad pagination forced when gets used on particular api call: no matter how many records finds, call alway returns data in pages. cannot request pagination on calls not default paginate. call either paginates or not. you cannot request change size of data pages; number of records returned in each page in paged set fixed each call using pages (in theory page size can vary each such call, in practice, (currently) not). there no threshold: either data in call returned in paged result set, or not. if number of matching results less page size, call should still return single data page within paged result set structure, property set indicate no further data pages available. yes...
