i have encountered similar problem described here (and in other places) - on ajax callback xmlhttp.responsetext seems ok (when alert - shows right text) - when using 'if' statement compare string - returns false. (i 1 wrote server-side code returning string) - after studying string - i've discovered string had "invisible character" first character. character not shown. if copied notepad - deleted first character - won't delete until pressing delete again. i did charcodeat(0) returned string in xmlhttp.responsetext. , returned 65279 . googling reveals sort of utf-8 control character supposed set "big-endian" or "small-endian" encoding. so, know cause of problem - but... why character being echoed? in source php use echo 'the string'... and apparently somehow outputs [chr(65279)]the string... why? , how can avoid it? to conclude, , specify solution: windows notepad adds bom character (the 3 bytes: ef bb ...

i found other entries question dealt specific methods, nothing comprehensive. i'd verify own understanding of used methods of data structure: o(1) - constant time: isempty() add(x) add(x, i) set(x, i) size() get(i) remove(i) o(n) - linear time: indexof(x) clear() remove(x) remove(i) is correct? help. the best resource straight official api : the size, isempty, get, set, iterator, , listiterator operations run in constant time. add operation runs in amortized constant time, is, adding n elements requires o(n) time. of other operations run in linear time (roughly speaking). constant factor low compared linkedlist implementation.

for example replacing @ at . @ least 1 study demonstrated effectiveness: to our surprise, none of crawlers visited our departmental research , course , research web pages led spam on email addresses containing at . another experiment demonstrated same thing, showing using at , dot reduced spam 2 orders of magnitude. the first study speculated spammers obtain enough plain-text email addresses ignore obfuscated ones. parsing at in addition @ should trivial. why don't spammers account such simple obfuscation? i no expert...but intuitively makes sense @ symbol less commonly used in non-email-related speech. @ sign set email address apart other text. if use at, blends in normal english. at pretty common word after :p i'm sure still possible parse out "at" version of email, more difficult of regex.

what correct usage of either, blockingcollection or concurrentqueue can freely dequeue items without burning out half or more of cpu using thread ? i running tests using 2 threads , unless had thread.sleep of @ least 50~100ms hit @ least 50% of cpu. here fictional example: private void _dequeueitem() { object o = null; while(socket.connected) { while (!listofqueueitems.isempty) { if (listofqueueitems.trydequeue(out o)) { // use data } } } } with above example have set thread.sleep cpu doesnt blow up. note: have tried without while isempty check, result same. it not because of blockingcollection or concurrentqueue , while loop: while(socket.connected) { while (!listofqueueitems.isempty) { /*code*/ } } of course take cpu down; because of if queue empty, while loop like: while (true) ; which in turn eat cpu resources. this not way of using concurrentqueue...

i need django app able restart apache server running it. i'm using mod_python. which easiest way? the way possible if gave django application root permissions, horribly unsafe. but, assuming app running root, can run import subprocess subprocess.popen(['/etc/init.d/apache2', 'restart']) or whatever command distribution has restarting apache. if django app not root, may able run sudo using pexpect python library. import pexpect child = pexpect.spawn('sudo /etc/init.d/apache2 restart') child.expect('[sudo] password .*:') child.sendline(password) child.interact() note way requires give apache user ability run sudo insecure. in general, can't see secure way accomplish this.

on company, have created new version of application in production. may guess, development composed multiple iterations , made multiple commits regarding same file. in order merging process (i'm using subclipse plugin) know if possible select last revision of given file, avoiding intermediate merges once "blocking" merging process. i recommend using svnmerge ; automates lot of confusing aspects of merging in subversion. with regards specific question, might if provide example of project structure in subversion , whether people have been working on separate branches. i'm not quite sure mean 'select last revision of file' - can merge whatever individual revisions like, won't merge cleanly if rely on earlier changes.

why work: self.array = newarray; but doesn't: [[self mutablearray] addobject:object]; meaning, why need init nsmutablearray work when don't have init nsarray ? edit: hops clearer guys. interface: @interface foo : uiviewcontroller { } @property (nonatomic, retain) nsarray *array; @property (nonatomic, retain) nsmutablearray *mutablearray; @end implementation: @implementation foo @synthesize array; @synthesize mutablearray; - (void)viewdidload { [super viewdidload]; self.array = [class returninganarray]; [[self mutablearray] addobject:objectihaveomittedthecode]; } @end self.array = newarray; in line, assigning created object self.array . so, you've no need create it. [[self mutablearray] addobject:object]; but in line trying add object array not created actually. if don't create array, nil , , sending message nil won't take effect.

the question may silly ,but want ask.. there way can declare method in class same signature different return type (like int fun(int) , float fun(int) ) , during object creation can dynamically decide function executed! have got compilation error...is there other way achieve logic may using templates... you can take return value template. template<typename t> t fun(int); template<> float fun<float>(int); template<> int fun<int>(int); can decide dynamically @ run-time call? no.

i lost scope of variables in rails mongoid. (probably due lack of coffee). all want, way set fields within application, way can find this, calling write_attribute . class example include mongoid::document field :foo def bar @foo = "meh" end def hmpf foo = "blah" end def baz write_attribute(:foo, "meh") end end e.bar #=> "meh" e.foo #=> nil e.hmpf #=> "blah" e.foo #=> nil e.baz #=> [nil, "meh"] e.foo #=> "meh" am using scope wrong? why running foo = "bar" not set field within, works outside: e.foo = "blah" works trough magic methods. try adding self attribute references when working in model's instance methods: def hmpf self.foo = "blah" end should trick.
