i developing product. there, separating page many templates, use atleast 5-8 ng-include per page. there problem use many ng-include in page? the major problem each ng-include generates http request, impact page load times. if doing splitting page, have couple of options: create directives, if html can used in others areas of app. use templating engine handlebars , preprocessor combine partials, in single page, gulpjs or grunt (i prefer gulp).

i trying validate 1 page, validator gives me ridiculous errors. for example attribute name not allowed on element meta @ point. i using <meta name="description" https://validator.w3.org/nu/?showsource=yes&doc=http%3a%2f%2fwww.ayurvedabansko.bg%2f the client wants code validated, crazy... anyone ideas? i fixed issues, , validating html source returns 2 info messages only. you main problem seems closing div tag without opening match. search <a href="#" class="scrolltotop"></a> , remove closing div tag right afterwards. here's list of fixes applied: closing div tag without opening match (as mentioned) <hgroup> being outdated/deprecated (try replacing div or p (besides div not support nesting hgroup tags (among others) inside it) make <title> tag 1st child in head element update : seems need define charset first thing before proceeding inside head tag. also, got rid of http-equiv...

i want read excel file in way slow. pattern should use read excel file faster. should try csv ? i using following code: applicationclass excelapp = excelapp = new applicationclass(); workbook myworkbook = excelapp.workbooks.open(@"c:\users\owner\desktop\employees.xlsx"); worksheet mysheet = (worksheet)myworkbook.sheets["sheet1"]; (int row = 1; row <= mysheet.usedrange.rows.count; row++) { (int col = 1; col <= mysheet.usedrange.columns.count; col++) { range datarange = (range)mysheet.cells[row, col]; console.write(string.format(datarange.value2.tostring() + " ")); } console.writeline(); } excelapp.quit(); the reason program slow because using excel open excel files. whenever doing file have com+ interop, extremely slow, have pass memory across 2 different processes. microsoft has dropped support reading .xlsx files using excel interop. released openxml library reason. i suggest use wrapper libra...

this doc google lists permissions groups under android m: https://developer.android.com/preview/features/runtime-permissions.html and doc links permissions in android permission group: https://github.com/android/platform_frameworks_base/blob/master/core/res/androidmanifest.xml now, not permissions existed pre-m exist post-m, leads question: happens these permissions after m comes out? for example, use_credentials belongs account permissions group - under m neither permission nor group exist. happens app using permission? still work fine? need ask different permission instead? must change manifest @ these unlisted permissions or unlisted permissions supported default post-m?

i have resourcemanager takes in classes of type resource . resource parent class of other classes such shaderprogram , texture , mesh , camera unrelated 1 another. suffice say, resourcemanager works. there 1 thing tedious , annoying, , that's when retrieve objects resourcemanager . here problem: in order object resourcemanager call either of these functions: static resource* get(int id); static resource* get(const std::string &name); the first function checks 1 std::unordered_map integer id; whereas second function checks std::unordered_map name manually given client. have 2 versions of these functions flexibility sakes because there times don't care object contained within resourcemanager (like mesh ) , there times care (like camera or shaderprogram ) because may want retrieve said objects name rather id. either way, both functions return pointer resource . when call function, it's easy like: rm::get("skyboxshader"); where rm typed...

i'm having uicollectionview gets populated different numbers of cells. cells should use available space perfect possible. compute available space per cell. the available space should computed when view initializes. each cell has spacing of 2pt everything. have hard code space of navigationbar , statusbar 64pt, not future proof. with code below working in simulator, not on real hardware (iphone5s): on physical iphone height not computed correctly , and gap 30pt appears between last row , bottom of collection view. any idea how improve code? private func computecellsizes(var size :cgsize){ if(size == cgsizezero){ size = self.collectionview!.frame.size } self.numberofrows = int(size.width / 103) //spacing of 2 points between each cell let availablewidth = size.width - cgfloat((self.numberofrows + 1) * 2) let cellwidth = availablewidth / cgfloat(numberofrows) self.numberofcolumns = int(size.height / (...

i want make simple ssl server/client couple using boost.asio. before doing have read ssl, certificates, private keys, public keys etc. used openssl generate private key (.key) , certificate (.crt). certificate self-signed. then, started digging boost.asio samples. first tried write client. in sample verify file *.pem file. had no idea was. after searching little (googling "how convert crt pem" etc.) got .crt file .pem file since starts -----begin , encoded in base64. so have done writing client , using .crt file argument of ctx.load_verify_file() . appropriate practice? to test client, have started writing server. have 3 kinds of files, 2 of them not familiar. are: certificate chain file private key file (the 1 familiar) temporary dh file in example private key file *.pem file, private key file *.key file. confused. need make conversion? so explain me: what *.pem file? how can represent private key verification? what certificate chain file? what temp...

i having list of products. have added google appengine search api index each product being each document. user can search products. far good. now want user able sort price of product ascending or descending. if have fixed price each product, build separate indexes , put documents inside them. unfortunately, prices dynamic. product price can change 3-4 times day. have more 200,000 products. since rewriting document each time price changes bad, have ndb datastore model has documentid , price entity attributes. is there way sort search api results, based on price in ndb model. alternate design solutions welcome.

i have nodejs->kafka>storm->mongo deployed in linux ubuntu. normal originally. changed method in storm worker makes storm worker process message slow, around 1 minute per message, notice message sent again , again storm. revert original method, fine. (original method process time 90ms per message). i guess storm reliability come player. when message not acknowledged, or time out, sends message again. if guess right, how configure timeout? if guess wrong, why same message sent twice or 3 times? you can set timeout via configuration parameter config.topology_message_timeout_secs . see https://storm.apache.org/javadoc/apidocs/backtype/storm/config.html#topology_message_timeout_secs the default value 30 seconds, see defaults.yaml here: https://github.com/apache/storm/blob/master/conf/defaults.yaml # maximum amount of time message has complete before it's considered failed topology.message.timeout.secs: 30 when tuple fails, should show in storm ui , sh...

i have 2 datatypes, a , b , have defined as: data = { afoo :: int, abar :: string } data b = b { bfoo :: int, bbar :: string, bbaz :: float } i need create heterogeneous list of a s , b s, define sum type, c , as: data c = ca | cb b i define functions cfoo :: c -> int cbar :: c -> string this can achieved pattern matching... cfoo (ca a) = afoo cfoo (cb b) = bfoo b cbar (ca a) = abar cbar (cb b) = bbar b ...but becomes tedious data types of many fields. wondering if there simple solution using template haskell, or if wouldn't worth effort. have intermediate knowledge of haskell, relatively new template haskell. appreciated.
