java - How is mutex internally implemented -

i've spent time trying understand how mutexes implemented in several languages. there multiple links describing topic (*) if understand correctly, hardware provides atomic operations may distinguish should in turn now. in software used busy waiting (try cas or test-and-set , wait in while cycle if not successful), how scheduler know should take away process/thread cpu because waits? there support in os provided example java synchronization uses in order signal "i blocked, please let other threads run instead"? think is, since busy-waiting alternative use lock(); (so should not same) *source: http://en.wikipedia.org/wiki/mutual_exclusion how mutex , lock structures implemented? in linux jdk soure c code uses pthread library part of standard c library. that, in turn, uses linux kernel futex feature ( man futex ). far can understand, implemented using kernel scheduler put calling thread sleep , wake when signal received. scheduler relies on timer in

autohotkey - Send hotkeys own default behavior -

how can send keys default (from hardware) behavior in own key definition. mean code: vcerc = 0 +c:: vcerc := !vcerc return ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; kkey = 0 $k:: if vcerc { kkey := !kkey if kkey sendinput {k down} else sendinput {k up} } else { send, k } return in end part send, k sends word k . in multi language environment means if switch other, key still sends k rather sending 1 second language (assume ن ). how can make send default? (from hardware no matter language is) two things seem off me: 1) initial kkey declaration never hit since falls after hotkey (and return). declare variables @ top. 2) if kkey true, script has holding down k button indefinitely. expected? 3) looking lowercase k's sending uppercase k's. expected? at rate, example should point in right direction. vcerc = 0 kkey = 0 +c:: vcerc := !vcerc return $k:: { if (vcerc) { kkey := !kkey if (kkey) { msgbox, k

How to get loggers in java.util.logging so i can change their log level at runtime? -

i using java.util.logging in different classes. log level's default value info . example in 1 class class1 setup way: import java.util.logging.handler; import java.util.logging.level; import java.util.logging.logger; public class class1 { private static final logger logger = logger.getlogger(class1.class.getname()); static { logger.setlevel(level.info); (handler handler : logger.gethandlers()) { handler.setlevel(level.info); } } ... } the above same way setup in different classes. now log level changed @ runtime. example suppose changed finest @ runtime. in case want loggers have been created far , change log level finest . how can that? thinking creating class logrepository has java.util.list , whenever logger created, add java.util.list of logrepository . think there may better way. i believe matter of setting level of parent logger of instances inherit from. logger.getlogger("").setlevel

c# - ref and out with value type variables -

msdn documentation on out says parameter passed out must assigned value inside function. example website: class outexample { static void method(out int i) { = 44; } static void main() { int value; method(out value); // value 44 } } according understanding when int "value" declared assigned default value of 0 (since int value type , cannot null.) why necessary "method" modify value? similarly, if "ref" used instead of out, there need of initializing "value"? there questions what's difference between 'ref' , 'out' keywords? no 1 wants put 2 , 2 together. according understanding when int "value" declared assigned default value of 0 (since int value type , cannot null.) no, that's not correct. a local variable isn't assigned value when created. space local variables created moving stack pointer make room them on stack. memo

javascript - Is it a good practice to allow a string or an array as argument to a function? -

here's example of i'm talking about: with grunt, have function: grunt.file.match([options, ] patterns, filepaths) in doc, say: both patterns , filepaths argument can single string or array of strings. so, practice allow different types same parameter? official doc in short, yes. in other languages can overload method different parameters. in javascript, not have luxury, have weak-type declarations. javascript not care pass, job make sure function accepts possible arguments. edit @jwatts1980 suggested, function should flexible enough handle potential arguments. if have parameter called name , should expect null , , chance might have receive array of names , in case might choose iterate on names ( name ) , whatever 1 name .

javascript - What is the "scope" that gets passed to a $scope.$watch function? -

$scope.$watch( function(scope) {return scope.anumber;}, function(newvalue, oldvalue) {alert("value changed");} ); }); what "scope" $scope.$watch takes in first function? (everything after info tangentially related). know "scope" without $ represent variable, in directive link function (scope, element, attributes, ngcontroller), etc. have no idea "comes from" here. it's connected controller's $scope, how? also, official doc states "the watchexpression called on every call $digest() , should return value watched. (since $digest() reruns when detects changes watchexpression can execute multiple times per $digest() , should idempotent.)" what's advantage doing return function rather saying $scope.valuetowatch (which doesn't work me, have seen people it). plunk working watch hell of it, don't need q: http://plnkr.co/edit/y86wr93xliao3wtwvst8?p=preview for reading same q later: article on $watch:
