i have installed 32-bit qt , have 64 bit compiled binaries opencv2.4.10 (from source). have 2 questions: i built opencv libraries before installing qt. understand, more use qt style ui not necessary interface qt. should rebuild opencv? when tried 64-bit qt, didn't work because opencv compiled vs 2013 - 32-bit. moved on 32-bit qt, still gives me linker errors of form: mainwindow.obj : error lnk2019: unresolved external symbol "void __cdecl cv::fastfree(void *)" (?fastfree@cv@@yaxpax@z) referenced in function "public: __thiscall cv::mat::~mat(void)" (??1mat@cv@@qae@xz) added include path , libraries in .pro file. getting error because qt 32-bit , using 64-bit opencv? i need use 64-bit opencv. there way can qt interface opencv? or other way have gui c++/opencv? thanks, if think happens when press compile button realise why cannot have 2 different architecture sets libraries. when compile program in 32 bit coded in way 32 ( coincidently 64)

i using connected sortable saves wonderfully via asp.net back-end on button click. additional features include ability search each of lists. works until drop , drag of item 1 list another. when search of 1 list using javascript search items in 1 list, still thinks part of first list. has seen behavior? , know of possible fix make item permanently part of said dragged upon list within dom. behavior in ff, ie, chrome, etc. now have buttons on list move items 1 list other based on them being selected button clicked, part of second list using jquery append();. makes item permanent part of second list's dom , able searched upon within list. so here "ah-ha" moment. doing supposed looking item , showing , if not item wouldn't show it. when item moved other column using sortable still had same class first column. needed make switch. the answer here follows... http://jsfiddle.net/6jmlvysj/ $(input) .change(function () { var filter

let's i'm working object of class thing . way i'm getting object bit wordy: bigobjectthing.uncle.preferredinputstream.nthrelative(5) i'd see if thing equal x or y or z . naive way write might be: bigobjectthing.uncle.preferredinputstream.nthrelative(5) == x || bigobjectthing.uncle.preferredinputstream.nthrelative(5) == y || bigobjectthing.uncle.preferredinputstream.nthrelative(5) == z in languages write this: bigobjectthing.uncle.preferredinputstream.nthrelative(5) == x |= y |= z but c# doesn't allow that. is there c#-idiomatic way write test as single expression ? just use variable: var relative = bigobjectthing.uncle.preferredinputstream.nthrelative(5); return relative == x || relative == y || relative == z; or if want fancy larger set of things: var relatives = new hashset<thing>(new[] { x, y, z }); return relatives.contains(bigobjectthing.uncle.preferredinputstream.nthrelative(5));

assuming need public web page displays email information user of site. in addition obfuscation, javascript helpful? settimeout(function(){ document.getelementbyid(id).innerhtml = "<span>" + username + "@" + hostname + "</span>"; },50) it entirely depends on spambot. could stop spambots, wouldn't stop scraper designed work around defense. that's how arms races work. it pretty straightforward build bot works around defense have in mind. use headless browser (such phantomjs) fetch page, evaluate javascript on page, wait arbitrary amount of time (say, 10 seconds), , then scrape dom email addresses.

i'd appreciate if can question. working radar (or spiderweb) plot gnuplot 5.0.0: the scale , range in axes same. numbers @ , beyond 1 have special meaning , highlight that. i thinking of 3 things increase visibility: simply make tick mark @ 1 (labelled "limit") boldfaced. how highlight specific tick , label? i highlight circular dashed line @ level 1 on plot i'd have background colored differently radius > 1. how can achieve either of 3 options above? 3 ideal of course, a minimum differentiation rest of value help. this generated plot in link: set term x11 set title "my title " set polar set angles degrees npoints = 6 a1 = 360/npoints*1 a2 = 360/npoints*2 a3 = 360/npoints*3 a4 = 360/npoints*4 a5 = 360/npoints*5 a6 = 360/npoints*6 set grid polar 360 set size square set style data lines unset border set grid ls 0 set linetype 1 lc rgb 'red' lw 2 pt 7 ps 2 m=2.2 set arrow 0,0 first m*cos(a1), m*sin(a1) set arrow 0,0 first

i'm constructing pretty long mysql query using python string.format() method. however, when try use more 10 fields ({0} {10}) tuple out of range error. when use 10 fields ({0} {9}), there's no problem. i need know how many fields .format() can handle , how address field on #9 if it's possible. thank you! there isn't limit number of placeholders can use; if index error have miscounted number of elements formatting in. {10} otherwise works fine: >>> '{0} {1} {2} {3} {4} {5} {6} {7} {8} {9} {10}'.format(*range(11)) '0 1 2 3 4 5 6 7 8 9 10' take account since counting starts @ zero , there eleven elements there. you should not, however, using str.format() produce sql queries. use sql parameters instead, ensure proper quoting (preventing sql injection security holes), , allow database re-use query plan of queries.

in asp.net web api 2 difference between setting httpclient accept header using following traditional method : httpclient client = httpclientfactory.create(handler); client.defaultrequestheaders.accept.add(new mediatypewithqualityheadervalue("application/json")); and following method : var headers = new dictionary<string, string> { {"accept", "application/json"}}; headers.foreach(h => client.defaultrequestheaders.add(h.key, h.value)); update 1: based on answer @darrenmiller in following post what overhead of creating new httpclient per call in webapi client? appears preferred method using defaultrequestheaders property because contains properties intended multiple calls. mean if set default header using simple dictionary httpclient client not efficient 1 uses defaultrequestheaders ? in addition cant understand how values inside defaultrequestheaders reused? lets create 20 httpclient cl

given app multiple widgets on it, each own title , whatnot, map each widget's elements, make them easy handle in tests. for example, page: this.widgets = element.all(by.css('ul.widget-grid')).map(function(widget, index) { return { index: index, title: widget.element(by.css('div.title')).gettext() }; }); and in spec: expect(page.widgets[0].index).tobe(0); expect(page.widgets[0].title).tobe('the title'); unfortunately, expects returning undefined . what doing wrong? i'm using protractor 2.0. this confused me thought i'd add answer others... while understood map() returns promise, because using in expect , thought resolved, , should act array. nope. returns object, looks array, not array.

when use temporary table gets created in database tempdb performance overhead. if create normal table in stored procedure in place of temp table created in own database. so question why use temp tables in procedure? is due scope of tables? we use temp tables 1 want store set of rows , work them not want interfere other instance of same piece of code, running on different connection. if worked permanent tables, we'd have work prevent interference (such filtering on @@spid ) or have restrict our code being executed single connection @ time. we benefit automatic clean when temp table falls out of scope. 1 or table variables. they're same, different scoping rules.

given rotate function 1 below, rotates array set number of slots. is there equivalent ramda.js function or composition rotation? var test = [1,2,3,4,5,6,7,8,9]; function rotate(arr, count) { arr = arr.slice(); while (count < 0) { count += arr.length; } count %= arr.length; if (count) { arr.splice.apply(arr, [0, 0].concat([].slice.call(arr.splice(arr.length - count, count)))); } return arr; } example rotate(test, 2) // -> [8, 9, 1, 2, 3, 4, 5, 6, 7] here's point-free 1 liner takes count first , data second, consistent ramda's composable style: const rotate = pipe(splitat, reverse, flatten); of course can flip(rotate) data first version. update sorry, read fast , assumed normal, left-wise direction rotation (eg, in ruby). here's variation of idea original does: const rotate = pipe(usewith(splitat, [negate, identity]), reverse, flatten);

i debugging application , when cursor retrieves pointer database, see this how can know means value behind @ ? how can bind address database value behind it? why need this? app behaving differently on 2 devices 2 android systems. cross debugging both , know cursor returned on each device. example, value behind @ on device 4-digit integer. the output of object.tostring() , number part hashcode() , not address. for cursor content debugging, have @ databaseutils.dumpcursor() .

i facing issue while concatenating elements of indexes 2 arrays. example: @x=(1,2,3,4); @y=(5,6,7,8); i want concatenate $x[0]"_"$y[0] like this: if @i=(..n), $x[$i]"_"$y[$i] suggest possible solution. to repeat process n elements in array, can following my @x=(1,2,3,4); @y=(5,6,7,8); @concatenated_array=(); $i (0 .. $n) # define $n <= min($#x,$#y) { push @concatenated_array, $x[$i] ."_". $y[$i]; } print "@concatenated_array\n";

while using entity framework code first 6, i'm trying replicate following model: class abstract class, implemented a1 , a2. additionally, class exposes navigation property, navigationpropertyb, class b abstract class implemented b1 , b2. class objects can have 1 class b object , bs can participate multiple times in class instances. currently i'm using table per hierarchy , b table per concrete type . class hierarchy mapped correctly , following mapping being used: modelbuilder.entity<a>() .map<a1>(m => m.requires("atype").hasvalue((int)atype.a1)) .map<a2>(m => m.requires("atype").hasvalue((int)atype.a2)) i understand it's similar concept i'm struggling working mapping model a's navigationpropertyb. can help? thank you! you're trying create one-to-many relationship between a , b , since each b can potentially have relationship multiple a s. problem he

i have sinatra app inherited sinatra::base class. in app have 1 helper method use in before filter. how mock such method in tests using minitest mock library? before unless valid_signature? halt 401 end end in order valid_signature? sinatra helper method, needs part of module. assuming module mymodule module mymodule def valid_signature? end end we can mock valid_signature? using minitest follows: mymodule.stub :valid_signature?, "stub return value" # method stubbed in block, run tests here # make sure module defined before stub it. end if running tests within block limiting, recommend looking @ mocha stubbing , mock library or manually redefining method @ runtime in test file: mymodule def valid_signature? # can redefine after class has been defined. "stub return value" end end

i have view in ios application (obj-c) has image view in centre, , below slider. image view shows album artwork, , slider can used adjust now-playing track position. there pair of left , right swipe gesture recognizers. these used skip next or previous tracks. the problem swipe gesture recognizers seem over-ride users moving slider thumb. in gesture recognizer code check point touched inside image view, still stops slider being moved. (the thumb moves, jumps it's original position when remove finger). this code use reject gesture if it's not inside image view. - (ibaction)swipeleftgestureaction:(uiswipegesturerecognizer *)sender { // location of gesture. cgpoint tappoint = [sender locationinview:_artworkimageview]; // make sure tap inside artwork image frame. if( (tappoint.x <0) || (tappoint.y < 0 ) || (tappoint.x > _artworkimageview.frame.size.width) || (tappoint.y>_artworkimageview.frame.size.height)) {

i have written library uses user defined class calculates defined properties in custom formula way. later user defined formulas used in library functions. formulas have permitted range common argument. user therefore has define minimal , maximal permitted argument values. before usage important check permitted argument range. the code below shows how done. user has write subclass class arguments min , max set_all_attributes() method. in method can implement custom code , has explicitly call check_value_range() method. subclassing needs boilerplate code, user has write each of many custom subclasses. call of check_value_range() method. now question: there better way implement boundary checking? may possible call check implicitly of metaclass? performance reasons, check should done once class attributes. from abc import abcmeta, abstractmethod class base: __metaclass__ = abcmeta def __init__(self, init_value=0): self.a = init_value self.b = ini
