5can give me hint speed following program? situation: have huge amount of measurement data. need extract data "10 minutes stable operation conditions" of 5 parameters i.e. column values. here (working, slow) solution: - take first 10 rows dataframe - compare min , max of each column first value of column - if @ least 1 column min or max not within tolerance, delete first row, repeat - if within tolerance, calculate mean of results, store them, delete 10 rows, repeat. - break when dataframe has less 10 rows since using repeat loop, takes 30min extract 610 operation points 86.220 minutes of data. any appreciated. thanks! edit: created code explain. please note deleted checking routines na values , standby operation (values around 0): n_cons<-5 # number of consistent minutes? ### function check wheter value within tolerance f_cons<-function(min,max,value,tol){ z<-max > (value + tol) | min < (value - tol); return(z) } # define +/- tolera...

does bootstrap have way specify justified columns, in same way tables? in other words, know want 6 columns across, using span2 give me 6 equal columns. inconsistent because of columns have less text others, , want them equally spaced. if resorted tables , didn't specify column widths, distribute each column width proportionately, giving me exact effect i'm looking for. any ideas? no, can not. not unless want tweak grid yourself. having span2 column has less width other span2 columns breaks layout , defeats point. one possibility create inner div inside column , give either padding or margins make content area smaller. otherwise, roll own grid , use instead. it's easy.

guys have 2 images 1 cmyk color model , other srgb.. find out color model better use while dealing image processing resizing, cropping, color filling etc.. in advance guys.. ! cmyk color space used print, (s)rgb used screens (web, monitors, tvs etc). if 1 open cmyk document in viewer/program doesn't support color profile (which not uncommon, since cmyk isn't supported rbg) colors appear extremely over-saturated. if altering images use on web, or in application, highly recommend use variant of rgb. in short, neither better other in general, depends on using images (apples , oranges, comes mind). cmyk better print, , (s)rgb better screens. update in response op's comment: just clear (forgive me if know this) color space/profiles not affect resolution of image, affect how colors handled/encoded. resolution affected file dimensions, dpi/ppi (dots/pixels per inch) , compression. update 2 in response op's comment: i'm not familiar "imagemagic...

consider link . see code: class myclass { public: myclass(); ~myclass(); private: int _a; }; myclass::myclass() { } myclass::~myclass() { } we can declare constructor out of class. why can declare constructor out of class , why should this? you cannot declare constructor out of class. talking constructor definition . class myclass { public: myclass(); // declaration }; myclass::myclass() // definition { } you should read this . the main reason why should define constructor outside class readability. clearer declare class in header file , define in source file. can apply rule members of class. a little quote standard : 12.1 constructors struct s { s(); // declares constructor }; s::s() { } // defines constructor

i've noticed std::chrono::steady_clock::now has noexcept specifier in documentation @ cplusplus.com . however, haven't found provision in latest c++11 draft (unfortunately don't have copy of standard). is mistake in cplusplus.com documenation or should std::chrono::steady_clock::now have noexcept specifier? § 20.11.7.2 of c++11 standard's definition of steady_clock : class steady_clock { public: typedef unspecified rep; typedef ratio<unspecified , unspecified > period; typedef chrono::duration<rep, period> duration; typedef chrono::time_point<unspecified, duration> time_point; static const bool is_steady = true; static time_point now() noexcept; }; so yes, std::steady_clock::now() should noexcept , isn't error in documentation. it seems cppreference says same .

i know bad description how can work: class test1(): def test_p1(): print("this part 1 of test1") def test2(): return test_p1() thanks in advance! well, there several options. the basic are: create instance first class test1(): def test_p1(self): print("this part 1 of test1") def test2(): return test1().test_p1() however, should use when having new instance makes sense (depends on api). make class method class test1(): @classmethod def test_p1(cls): print("this part 1 of test1") def test2(): return test1.test_p1() make static method (discouraged) class test1(): @staticmethod def test_p1(): print("this part 1 of test1") def test2(): return test1.test_p1() alternative: use inheritance in cases (maybe case too, not know) makes sense utilize inheritance: create class inherit test1 . way can override parts of , refer parent methods. example: class t...

an ios app can register handle url scheme when it's installed. officially, "if more 1 third-party app registers handle same url scheme, there no process determining app given scheme," according the "communicating other apps" section of apple's "advanced app tricks" . in practice, though, seems app registered handle url scheme 1 it's given to. in event second app has registered handle url scheme app registered, possible first app somehow "reregister" handler url scheme without reinstallation? i have no proof @ hand, pretty sure registration url schemes registration file type handling etc. installation time procedure. however, experience, providing update via app store , updating app triggers installation procedure (since updated app may register new url schemes). hence, if keep apps "up date" providing frequent updates, ios should prefer (and point of view, unofficial rule recent handler used, makes sense)....

currently have verbal agreement in checking code code should complied without errors, unit tested (with unit tests passed), @ least 80% coverage, complexity less 10, documented java comments , should reviewed team. @ point should fine check in (using perforce). know visual studio have team edition can enforce rules , prevent check ins unless rules have been satisfied. use sonar test our code, want prior checking in enforce dev team follow these rules. there such method java perforce or eclipse? thanks you can use perforce pre-submit trigger, here few examples: http://public.perforce.com/wiki/pre-submit_trigger_examples update: since "change-content" pre-commit triggers give access not list of files content of changed files, in principle write trigger applies these changes full content of branch , runs sonar on it. however, sense triggers typically used brief validations rather more complex processing takes long time execute. longer validations tend belong...

i'm developing newton os app in newtonscript , protoapp proto fits application type better newtapplication proto (i.e. newtapp). protoapp provides title & status bar close box, how insert custom buttons in status bar (since shows clock)? i found this thread on newtontalk , paul guyot says: you don't need use protoapp. can use protofloater instead. can add nicer newtonos 2.x-like status bar replace ugly clock/battery picker of protoapp , put close box on bar. trick steal bar newtapp framework, i.e. use newtstatusbarnoclose. did several projects, it's documented in doc (the fact can use newtstatusbar[noclose] instead of protostatusbar) , can take advantage of buttons handling code (to align them automatically on left , on right). it turns out suggestion of using newtstatusbar instead of protostatus is documented in newton programmer's guide (2.0) on page 7-19: note new status bar protos newtstatusbarnoclose ...

i rotate uiview around center point without rotating uiview itself. more cars of ferris wheel (always staying upright) opposed hands of clock. the times i've rotated uiviews around center point, i've used layer position/anchorpoint/transform accomplish effect. changes orientation of view itself. any help? keller this pretty easy in core animation. i've used pretty boring static values example, you'll want make modifications. show how move view along circular uibezierpath. uiview *view = [uiview new]; [view setbackgroundcolor:[uicolor redcolor]]; [view setbounds:cgrectmake(0.0f, 0.0f, 50.0f, 50.0f)]; [view setcenter:[self pointaroundcircumferencefromcenter:self.view.center withradius:140.0f andangle:0.0f]]; [self.view addsubview:view]; uibezierpath *path = [uibezierpath bezierpathwithovalinrect:cgrectmake(cgrectgetmidx(self.view.frame) - 140.0f, cgrectgetmidy(self.view.frame) - 140.0f, 280.0f, 280.0f)]; cakeyframeanimation *pathanimation = [cakeyfr...
