i want info twitter project, i'm using tweetstream gem, , works in code, need done background process in heroku script. i'm using event machine gem so, , works in computer, haven't been able make run on heroku on it's own. i've read need use procfile , worker process, can't make work, on local works fine. i'm new background process , working servers. heroku dynos not support background processes in "free" or "hobbyist" tiers. here heroku documentation on background jobs . it costs $30 bucks month add on. there other implementation hurdles overcome local server vs. heroku background jobs. best starting point can give heroku not support background jobs default. have "scale worker dynos"

for purposes of our frontend app, need ingest array of objects (say 20), convert array key/value object. data = [ {name: 'first', uid: 789, start: '2016-01-20 08:00:00'}, {name: 'second', uid: 492, start: '2016-01-20 15:00:00'}, {name: 'third', uid: 324, start: '2016-01-20 10:00:00'}, {name: 'fourth', uid: 923, start: '2016-01-20 14:30:00'}, // ... ]; i run sort on start data.sort(function (a, b) { var astart = new date(a.start), bstart = new date(b.start); if (astart < bstart) return -1; if (astart > bstart) return 1; return 0; }); then, purpose of quick-access data based on uid, loop through sorted array convert k/v object: var stored = {}; (var = 0; < data.length; i++) { stored[data[i].uid] = data[i]; } this allows me stored[uid] instead of having loop through data every time need index of given object. issue in looping through , creating st...

i started git merge, made local changes want keep. no longer want merge, , instead continue work on local changes. how do this? first, copy folder you're working in in case bad happens. git pretty bulletproof, if start using git reset --hard , it's possible bad things happen. then, git commit --patch , picking changes want keep , leaving merge did. once you've committed changes, git reset --hard , , merge should gone, changes should still there.

this seems way can jasmine tests run through karma @ moment: src/js/voice.js describe("speak", function () { var input = "success"; var output = voice.prototype.speak(input); it("should return input value", function () { expect(output).toequal(input); }); }); spec/voicespec.js var voice = function () {}; voice.prototype.speak = function (string) { return string; };

i have problem .lib files not found. check linker properties. however, in project->properties, cannot find linker tab. missing here ? actually, fear not looking @ project properties, @ properties solution or whatever. project (which icon in vs instance), or can @ project properties ? thanks !! if there no linker options, possible project set build *.lib. in case able select 'librarian' on left of project options. can modify project configured build going general , changing configuration type. to project properties, right click on project in solution explorer window , click on properties.

when doing cross-validation model selection, found there many ways quote "standard deviation" of cross-validation scores (here "score" means evaluation metric e.g. accuracy, auc, loss, etc.) 1) 1 way calculate standard deviation on mean of scores of k folds (= standard deviation of k folds / sqrt(k)). 2) second way calculate standard deviation of scores of k folds. example can found here: http://scikit-learn.org/stable/auto_examples/svm/plot_svm_anova.html 3) way don't understand. seems calculate standard deviation of k folds / sqrt(n) n size of dataset... http://scikit-learn.org/stable/auto_examples/exercises/plot_cv_diabetes.html personally think 1) correct, care more standard error on sample mean (here = average score of k folds validation) rather standard deviation of sample. can explain way preferred?

i'm looking find out if there's nice, "native" way construct object given pyobject* known type. here code stands: c++ void add_component(boost::python::object& type) { auto constructed_type = type(); // doesn't construct anything! } python o = gameobject() o.add_component(cameracomponent) my code executing entire function fine, constructor never triggered cameracomponent . so question is, how i, given pyobject* known a type, construct instance of type? many in advance. if boost::python::object references type, invoking construct object referenced type: boost::python::object type = /* py_type */; boost::python::object object = type(); // isinstance(object, type) == true as in python object, accepting arguments python boost::python::object allow type of object, not type. long object callable ( __call___ ), code succeed. on other hand, if want guarantee type provided, 1 solution create c++ type represents python type,...

i have list of n lists, each sub-list containing m elements. how create list of m lists n elements each, containing n-th elements initial lists? let's have this mylist = [[1, 2, 3],[4, 5, 6]] i want have [[1, 4],[2, 5],[3, 6]] performance important. have sublists of millions of elements (though, 1 dimension small: 1.000.000 x 8 ) this give tuples, it's trivial extend contain lists: zip(*mylist) i.e. [list(i) in zip(*mylist)]

i want modify element's value in double-linked list, don't know how pointer, because element's value nil interface defined go-lang itself. far know is, must type assertion before element's value like: val, ok := ele.value.(type) if ok { // something... } but if modify val useless. hint? thanks. there 2 pretty straight forward options. they're going involve type asserting because you're using interface{} you can store pointer , type assert: var q interface{} var int q = &i *(q.(*int)) = 5 you can reassign it: var q interface{} q = 5 b := q.(int) q = 2*b i think reassigning makes sense. if you're doing in function need return new value. i'm sure there other ways change around, think simple best. of course in real work checking nice.

i trying background colour of coloured box when clicked , subsequently storing in variable using either javascript or jquery. although trivial information, noticing is, javascript , jquery show in different manner. for example, coloured box using red (in css, giving background-color: red). therefore, when click box id ( #box ) using following code in javascript var bcolour = document.getelementbyid("box").style.backgroundcolor; console.log(bcolour) gives me value red . whereas same in jquery var bcolour = $(#box).css("background-color"); console.log(bcolour) gives me value rgb(255, 0, 0) . is there way jquery display bcolour value identical javascript shows? jquery.css uses getcomputedstyle function. ref there no difference between getcomputedstyle(object).getpropertyvalue(property) , jquery.css for example document.getelementbyid("mydiv").style.backgroundcolor // return red; getcomputedstyle(document.getelementb...

i see potentially answered in question must call atomic load/store explicitly? . so sake of clarity restate question succinctly in hopes future readers find clear. is std::atomic<bool> b(false); bool x = b; same std::atomic<bool> b(false); bool x = b.load(); and std::atomic<bool> b(false); b = true; same std::atomic<bool> b(false); b.store(true); if indeed case then: why have 2 options? apparent benefit? is practice when dealing atomics prefer more verbose load()/store() on potentially confusing assignment(=) mean either depending on whether lhs or rhs atomic. note aware of fact both variables cannot std::atomic i.e lhs , rhs not possible read , write atomically in 1 instruction. yes, same. think reason overloaded operators provided convenience. not mention making easier convert existing code use atomics. personally, prefer explicit load , store always. think it's better practice , forces remember you're de...

i'd have method accepts hash , optional keyword argument. tried defining method this: def foo_of_thing_plus_amount(thing, amount: 10) thing[:foo] + amount end when invoke method keyword argument, works expect: my_thing = {foo: 1, bar: 2} foo_of_thing_plus_amount(my_thing, amount: 20) # => 21 when leave out keyword argument, however, hash gets eaten: foo_of_thing_plus_amount(my_thing) # => argumenterror: unknown keywords: foo, bar how can prevent happening? there such thing anti-splat? this bug fixed in ruby 2.0.0-p247, see this issue .
