c# - What is the difference between EnumerablePartitionerOptions.NoBuffering and not using Partitioner at all? -


in case have collection of objects each object's process takes lots of time, difference between enumerablepartitioneroptions.nobuffering , not using partitioner @ all?

http://msdn.microsoft.com/en-us/library/system.collections.concurrent.enumerablepartitioneroptions.aspx

enumerablepartitioneroptions.nobuffering:

create partitioner takes items source enumerable 1 @ time , not use intermediate storage can accessed more efficiently multiple threads. option provides support low latency (items processed available source) , provides partial support dependencies between items (a thread cannot deadlock waiting item thread responsible processing).

thank you.

update: faster? , why?

ienumerable<int> numbers1 = enumerable.range(1, 100); parallel.foreach(numbers1, (number1) => veryexpensivemethod(number1));             //             // partitioner<int> numbers2 = partitioner.create(enumerable.range(1, 100),   enumerablepartitioneroptions.nobuffering); parallel.foreach(numbers2, (number1) => veryexpensivemethod(number1));

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
