in software i'm maintaining i've observed com classes marked identical [progid] s. afaik progid human readable identifier component , should map 1-to-1 component's clsid . so i'm wondering: is there reason have same progid different classes? what possible consequences? (except not being able reach component using convenient way) thanks in advance. a progid provides friendly name clsid guid of coclass. important scripting languages, no way know guid. used languages support late binding, vb.net , c#. conversion string guid happens @ runtime. usual name of factory function createobject(), language runtime implements looking @ registry entry stored in hklm\software\classes. which cue go wrong when duplicate them. actual object client program creates random. whichever 1 happened registered last. client program calls different method 1 intended call. might trigger disp_e_xxxx error return that's no guarantee. in general nasty , quite

i create ids following: var plant_counter = 0; $('.plant-name').attr('id', 'plant-name-' + plant_counter); after try change html code of element: $('#nav-btn-test').click (function () { $('#plant-name-0').html('hello'); console.log('clicked); }); the html code not change. why? the code setting ids not work because variable plant_counter not being updated (it 0). use jquery's .each method (see documentation here ), this: $('.plant-name').each(function( index ) { $(this).attr('id', 'plant-name-' + index); }); aside : in click handle registration, you're missing closing single quote (') @ end of logging statement. here working example jsfiddle copy.

i start process in worker upon payload receive through message queue power ironmq. ironmq it's possible create push queue requires http endpoint. is possible set http endpoint heroku worker or have pull queues worker? there few options: 1) if you're using heroku worker, you'll have poll ironmq messages. easy, in loop ruby example: while true msg = queue.get if msg != nil process_message(msg) else sleep 1 # sure sleep don't waste api calls , cpu! end end 2) use ironmq push queues hit endpoint on heroku app, instead of using heroku worker , put process_message code endpoint. 3) use ironworker .

storing boolean value in localstorage, value converted string. trying converting value localstorage boolean, need use json.parse() method, more handy !! doesn't work. code sample: var test = false; localstorage['test'] = test; console.log("json.parse returns: ", json.parse(localstorage['test']), "expected: ", test); console.log("'!!' returns: ", !! localstorage['test'], "expected: ", test); -jsfiddle- i'm quite confused why behaviour. explaination? ps: using getter/setter localstorage methods doesn't matter here, same result. local storage stores strings , i'm afraid, whatever input (if feed object, converted automatically standard tostring() method)... you're doing !! test on string, true . you should use json.stringify() , json.parse() when dealing store in dom storage

performance difficult subject, let me try anyway. i'm using app engine mapreduce straightforward analysis , feel i'm not getting kind of performance expect. i have app engine module dedicated running single mapreduce pipeline. the module instances use basic scaling, instance class b4_1g , 16 maximum instances. the pipeline uses queue allows 100 concurrent requests. the pipeline uses 64 shards. as example of kind of performance i'm seeing, here 1 of map functions: map(data): """data handle cloudstorage file""" line = data.readline() while line: val in creates_values(line): yield val line = data.readline() data.close() the create_values function yields 1-5 strings, each forming single line in output. particular run i'm doing, each input file cloudstorage ~3mb or ~19k lines , each output ~14mb. have 64 of these files (one each shard) , processing time 4-10 minutes each shard. now,

i have here windows forms application using notifyicon everything works fine in win 7 environment, until win10 came... the content of notification balloon has 9 lines. but when run app in win10, lines of notification content not shown in balloon. how can resize balloon in win10? [correct] win 7 notification: [not good] meanwhile in win 10: [update] notification balloon won't show in 64-bit os. 😴 i don't believe possible without hacking, if want examples on doing written here: http://www.codeproject.com/articles/37912/embedding-net-controls-to-notifyicon-balloon-toolt i advice you, if possible, move wpf (or use mix). wpf there component allows use custom popups. information on can found here: http://www.hardcodet.net/wpf-notifyicon

background. want our users check if metadata read out of several images correct. therefore, show retreived data in formset let user check everything. in case metadata has errors (that happens) display them form errors here. problem. obtain error messages need bound forms. feeding our various data bound modelformset , taking care of managementform ... not simple. unbound version works fine. idea. if produce unbound form , submit within python code , simple way post data need create bound form.

given function takes variable number of arguments, e.g. def foo(os: string*) = println(os.tolist) how can pass sequence of arguments function? write: val args = seq("hi", "there") foo(args) obviously, not work. foo(args:_*) trick. instead of applying sequence 1 single argument, each element in sequence used argument.

i want label objects in binary image using find contour , drawcontour function. i want know data stored in output array of findcontour function. further, there other suitable methods above? @berak's comment answered already. i'll add part of how output like. consider 35x62 image 5 times enlarged version below. image has 6 blobs or objects each of has corresponding contour. the above image stored in mat object im . findcontour applied as cv::findcontours(im.clone(), contours, cv_retr_external, cv_chain_approx_none); the output of findcontour vector<vector<point>> object contours looks like: so, has 6 elements each corresponding 1 contour. let's take contours[0] example. looks like: contours[0] has 5 elements, each of stores coordinates of pixels form contour.

i trying started automated build process using jenkins. so far have managed jenkins build project bitbucket, run tests , upload files production server using publish on ssh plugin. when delete files git repo, files deleted on remote server. there few ways have thought doing already. wipe files on production server, upload latest build release. seems bad solution me, cause more downtime like. create script lives on remote server clean files after new build process. need find out git (somehow?) deleted files on commit were. instead of having jenkin use publish on ssh plugin, have git installed on production server, after successful build, can jenkins (somehow?) push project git production server. this seems common task developers, , feel missing here. there standard practice this.
