i've switched roots sage starter theme wordpress: roots.io/sage/docs/ , i'm reading on deployment processes. my processes usually: - make changes - build grunt/gulp - commit (including compiled scripts) - deploy sage's .gitignore file removes dist folder (compiled files) repo ie. no css/js in repo. supposed install node/npm , build assets on staging/production environment after deploy? if so, how trigger gulp/grunt task on remote server after deploy? i'm using https://www.springloops.com/ managing git , deploy. are supposed install node/npm , build assets on staging/production environment after deploy? you should avoid doing this. there mixed opinion committing compiled assets vcs stated doing previously, too. let's @ example. you finished testing locally. haven't run npm update in few days , 1 of dependencies has loose version constraint specified; "~1.0.0" . you deploy. on server, npm install run before gulp or grun

i have shell script uses array. script cycle through entries of array reason first , last entry has problem. the array: queue_names=( clqueue dlq expiryqueue ) the loop: for in “${queue_names[@]}” #do stuff done i can see in console , shows first entry shows: �clqueue. last entry shows: expiryqueue� i'm guessing these markers know start , end of array. unfortunately interfering functionality of script. use these queue names search , fails find because of added character. how rid of them or there code change avoid problem? “${queue_names[@]}” not "${queue_names[@]}" , because “” not "" . "smart quotes" aren't recognized quotes @ in bash; thus, effect same if expansion had been unquoted -- string-splitting , glob-expansion on array contents -- literal "quotes" grafted around start , end characters. you need use real quotes -- "" -- not opening/closing "smart quotes" created word proc

in other words these 2 different blocks of code equivalent? es6 class extend based class child extends parent { // define subclass } var myinstance = new child(); object.assign based var myinstance = object.assign(new parent(), { // define subclass } in particular use case trying extend (facebook's) flux dispatcher. in examples use object.assign. es6 class extend, worried there subtle differences between 2 should stick object.assign. no, these code blocks not equivalent in class inheritance example new constructor makes objects having features parent class. extending objects via object.assign example of mixins . add properties 1 instance not change future children. unlike child classes, instance after extension still have constructor property pointing parent . means can't recognize extended child among non-extended, because have same constructor , operator instanceof give same result. can't access overridden methods in child, because l

this question has answer here: c++ class definition split 2 headers? 1 answer can have class in c++, in different .hpp files? because have class called map 5000 lines , wonder know if can split in 2 or 3 files same class name, , if other headers see class if wasn't split. no, can't that. besides, class way big. instead of trying split lexically, consider splitting semantically , multiple classes. read single responsibility principle . in short, there moderately serious design problem @ core of question.

based on following setup of kubernetes on microsoft azure . i able deploy docker containers, using same configuration settings. we have 2 categories of containers, front-end , back-end, back-end consist of high intensive processing. latter want run on large instances, whereas front-end run on small instances. what best option separate these, gues labeling hosts. not able find in docs, or in examples. currently, adding labels hosts , restricting pods nodes appropriate label (e.g. 'large' / 'small') best way this. example, see examples/node-selection kubernetes has resource model which, once implemented, allow tell scheduler resources each pod needs , system ensure pod placed on node available resources. unfortunately, can tell design document on github, isn't implemented yet.

is possible have multiple stylesheets single qt application , select of them needed? for instance, have different styles of push buttons within application. understand have like: qpushbutton { background-color: green; } and push buttons have green style per above line. however, have stylesheet somehow this: qpushbutton1 { background-color: blue; } qpushbutton2 { background-color: green; } i may need place several push buttons in application , each of those, want select either qpushbutton1 style or qpushbutton2 style. is feasible within 1 or multiple stylesheets, can use setstylesheet() enable custom style? thanks! you can use global stylesheet , set special settings each special object name. #qpushbutton1 { background-color: blue; } #qpushbutton2 { background-color: green; } but in case need set these object names in code. can done with: ui->pushbutton1->setobjectname("qpushbutton1"); ui->pushbutton2->setobjectname("qpushbutto

if have if(object.keys(obj) < 2) have bug might slip past tests if don't test objects property counts below , at/above 2. i.e. should have .length . if linter check type on either side of <,>,<=,>= warn this. alternatively, how else catch this? know more high quality tests catch this. problem never know when have enough high quality tests. if linter or other tool had ability warn of types in situation automatically caught. there no conclusive way check type equality in linter without running code because code can sorts of things , linter can't know might present in variable when used in comparison. consequence of using language such javascript not require strict typing. there variants of javascript such typescript (that can compiled javascript) offer more capabilities in regard.

i'm developing android app using opengl es 2. problem encountering glclear() function taking long process game appears jittery frames delayed. output of run of program timing probes shows while setting vertices , images atlas takes less 1 millisecond, glclear() takes between 10 , 20 milliseconds. in fact, clearing takes 95% of total rendering time. code based upon common tutorials, , render function this: private void render(float[] m, short[] indices) { log.d("time", "--start render--"); // handle vertex shader's vposition member int mpositionhandle = gles20.glgetattriblocation(rigraphictools.sp_image, "vposition"); // enable generic vertex attribute array gles20.glenablevertexattribarray(mpositionhandle); // prepare triangle coordinate data gles20.glvertexattribpointer(mpositionhandle, 3, gles20.gl_float, true, 0, vertexbuffer); // handle texture coordinates location int mtexcoordloc = gles

i'm having issues injection in application i'm working on (using spring version 3.1.2). start with, i'm seeing lot of code this: @value("#{searchrequestbean}") private searchrequest searchrequest; @value("#{searchresponsebean}") private searchresponse searchresponse; @autowired private savedsearchservice service; each of these 3 appears have effect of autowiring specified bean/service class. don't understand is, what's difference between @value , @autowired in these cases? every example find online seems use @value inject values properties file. in case, searchresponse , searchrequest abstract classes. i'm hoping better understanding of me solve issues i'm having session bean. @value can used injecting default values. example inject default of string value of property file. in example, @value used set default value of class spring managed bean. @autowired can't used first example: it's not proper

would run issue if tried dropping foreign key constraint on live sql database? want make sure there's no reason take database offline before doing this. dropping foreign key on live databases can done online without impacting users. may run data quality issues though, guess foreign key in place reason.

when select table oracle, want handle 1 col'val : eg: 'ab,cd,ef' 'ef->cd->ab'; 'ab,bc' 'bc->ab'; 'acnn,bbccac' 'bbccac->acnn'; 'bbbdc，dccx，fff' 'fff->dccx->bbbdc' we have 2 tasks. first tokenize original strings. quite easy regular expressions (although there more performant approaches if dealing large volumes ). second task re-assemble tokens in reverse order; can use 11gr2 listagg() function this: with tokens ( select distinct col1, regexp_substr(col1, '[^,]+', 1, level) tkn, level rn t23 connect level <= regexp_count (col1, '[,]') +1 ) select col1 , listagg(tkn, '->') within group (order rn desc) rev_col1 tokens group col1 / here a sql fiddle .

why following work? thought writing an index of vector object beyond end of vector object cause segmentation fault. #include <iostream> #include <vector> using namespace std; int main() { vector<int> x(1); x[10] = 1; cout << x[10] << endl; } what implications of this? there safer way initialize vector of n elements , write those? should use push_back() ? somebody implementing std::vector might decide give minimum size of 10 or 20 elements or so, on theory memory manager has large enough minimum allocation size use (about) same amount of memory anyway. as far avoiding reading/writing past end, 1 possibility avoid using indexing whenever possible, , using .at() indexing when can't avoid it. i find can avoid doing indexing @ using range-based for loops and/or standard algorithms tasks. trivial example, consider this: int main() { vector<int> x(1); x.push_back(1); (auto : x) cout << <<

i running issue gae , session management. i have endpoint creates , stores user information in session upon successful login. however, unable retrieve information on client side. 1 thing i've noticed jsessionid , gae session id being different. session being created in google's datastore said, id differs 1 on client side (jsessionid). i have tested using servlet instead of endpoints , works charm... did in order pinpoint root cause downsize code basic example (see below). any idea root cause is? appreciate help. thanks. gae endpoint @apimethod(name = path.operationurl.test, path = path.operationurl.test, httpmethod = httpmethod.post) public response test(httpservletrequest request) throws databaseexception { string name = request.getparameter("name"); string pwd = request.getparameter("pwd"); //creating session httpsession session = request.getsession(); session.setattribute("name", name); session.setattri

i provide drawables different densities (mdpi, hdpi, xhdpi, etc.) , work fine, 10-inch 1280 x 800 tablet not high density (150dp?) , relatively low-density drawables scaled large size. doesn't good. my app larger like, want avoid copying more drawables bunch of different drawable-large-mdpi , drawable-large-ldpi , etc. folders. i don't know how many screens today still ldpi , mdpi, want support smaller screens while still looking on large screens, large screens lower density. there standard or recommended approach this?

i stupidly ran git reset --hard on branch. in wrong branch. unfortunately, didn't perform git add . . there way work? no. not believe there method local code if never added local or git repository @ point. if added @ point, use git fsck last deleted data added @ point. there stack overflow here talking possibility

i have dataframe columns trip_id, service_id etc., like trip_id service_id 1 weekday 2 weekday 3 weekday 4 saturday 5 saturday 6 holiday 7 sunday i want print out trip_id's 'weekday', saturdays , holidays, separately. tried join_df.query(join_df['service_id'] == 'weekday') way, doesn't seem right one. tried print join_df[join_df.service_id =='weekdays'] didnt work. got empty dataframe output. could me please. thank you this looks typo (it's weekday not weekdays), either latter or using loc should work: in [11]: df[df.service_id == 'weekday'] out[11]: trip_id service_id 0 1 weekday 1 2 weekday 2 3 weekday in [12]: df.loc[df.service_id == 'weekday'] out[12]: trip_id service_id 0 1 weekday 1 2 weekday 2 3 weekday you can use query, syntax isn't quite

i trying write yarn application , hoping suggestions on few design questions had in mind. have gone through simpler sample apps distributed shell , variations of familiar basic api. create application has web interface user can interact , potentially provide kind of tasks (nature of tasks irrelevant). based on work, ui requests containers processing. the ideal arrangement comes mind application master provides web ui , no containers allocated until comes website , requests work. @ point, should able register new containers , allocate work them. if provides web ui , understanding chosen rm every time application submitted rm. means can have different ip and, therefore, different url upon application restart. behavior suggests should not used such purpose , potentially different application (non-yarn) can provide web ui , better suited it? in examples, have seen sample yarn apps requests containers part of invocation. can please point related apis allow requesting containers @

i have following html: <div id="one"></div> <div id="two"></div> when run following code in jquery: $(function () { var span = $("<span>name</span>"); $("#one").append(span); $("#two").append(span); }); the span added last div: <div id="one"></div> <div id="two"><span>name</span></div> i'd expect added both divs, why it's not? each dom element can connected 1 specific parent. can't append same dom element 2 dom parents. refer so in case, must clone node. $(function () { var span = $("<span>name</span>"); $("#one").append(span); $("#two").append(span.clone()); }); <script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script> <div id="one"></div> <div i

i have large image(10000*10000) , several reasons cannot modify (like chop smaller tiles.) i don't want display whole image small section of improve gui efficiency. when user click , drag around, new part of image displayed in viewport. so, how pull section of image data on fly? i don't recall qt providing support working partial images in case of high resolutions. maybe libtiff . basically, image composed of either strips or tiles, can use tiffreadscanline() or tiffreadencodedstrip() respectively load portions of image. can compose image appropriate resolution viewport. alternatively, take @ qtiffhandler class, private class in qt not directly accessible, copy , if necessary modify source expose functionality. internally uses libtiff well.

i using ruby on rails , koala library interact facebook. use put_wall_post api post on user wall. api takes link , picture url among other parameters. before change on fb side few months back, picture url used show picture of our application (or whatever passed) when app posted on user's wall. fb later on changed mechanism , use link parameter. when call put_wall_post api, fb gets call, use link attribute send crawler scrap page @ link picture og:image tag. after crawler call returns, put_wall_post api returns. simple wall post results in 2 round trips. noticed take 2-3 seconds or takes 8-9 seconds before crawler comes our app page. put_wall_post api takes 2-3 on in cases 8-9 seconds before returns. , creating huge experience issue users since whatever doing (which resulted in wall post) takes long , have wait... note can't call put_wall_post on background thread outcome of needs reflected user in way... why fb have use mechanism opposed previous way of looking @ pictur
