i got these includes work angular offline because of ajax works in firefox. there way work in browser locally no internet. demo non computer savvy people have use. <!-- test --> <div ng-include src="'_includes/link.html'"></div> so users not know how go command prompt etc. normally use like: <div data-ng-include="'_includes/link.html'"></div> reference

so when using swift 1.2, function worked fine , gave me functionality needed. func mapview(mapview: mkmapview, rendererforoverlay overlay: mkoverlay) -> mkoverlayrenderer { if overlay mkpolyline { let pr = mkpolylinerenderer(overlay: overlay) pr.strokecolor = self.lightblue pr.linewidth = 14 return pr } //i error here, because need return } now, error saying "missing return in function expected return 'mkoverlayrenderer'". is still how method used? can remedy this? func mapview(mapview: mkmapview, rendererforoverlay overlay: mkoverlay) -> mkoverlayrenderer will called each overlay add instance of mkmapview. if add mkpolyline mapview, can sure when delegate function called, overlay parameter of type mkpolyline . since case, there no reason check if overlay parameter instance of mkpolyline if overlay mkpolyline . can this: func mapview(mapview: mkmapview, rendererforoverlay overlay: mkoverlay

i sent jquery ajax request express-powered node.js server, processed , responded. however, response triggers ajax error callback instead of success callback (despite status code being "200"). not expecting. ;o) here code: client.js: $.ajax( { url: "/httpupload", type: "post", processdata: false, contenttype: false, datatype : "json", data: formdata, success: function() { // stuff }, error: function( error ) { console.error( "httpupload failed: " + error.responsetext ); } } ); server.js: var express = require( "express" ); var app = express(); var server = require( "http" ).server( app ); var multipart = require('connect-multiparty'); app.use( express.static( "public" ) ); app.use( multipart() ); app.post( "/httpupload", function( req, res ) { console.log( "received post request"); res.send( "

i have string reads parsegeopoint[30.132531,31.312511] . how can coordinates saved in double variables. i.e. want have double lat = 30.132531; , double lang = 31.312511; here have tried: string mytext = "parsegeopoint[30.132531,31.312511]"; string [] latlong= mytext.split("["); //it needs escape character string [] latlong2= latlong[1].split(","); double lat = double.parsedouble(latlong2[0]); string[] latlong3= latlong2[1].split("]");//also escape character needed here double lang = double.parsedouble(latlong3[0]); two things: how split on square bracket given needs escape character? second, feel in way. there must simpler way. it? how split on square bracket given needs escape character? i guess mean doesn't compile: string [] latlong= mytext.split("["); to make compile, escape [ : string [] latlong= mytext.split("\\["); here's way extract doubles string using regular expression

upto extent should fill missing values feature in dataset doesnt become redundant ? i have dataset has max of 42000 observations. there 3 features have around 20000, 35000 , 7000 values missing. should still use them filling these missing values or dump these 3 features? how decide threshold keeping or dumping feature given number of missing values of feature ? generally, can interpolate missing values nearest samples in dataset, manual pandas missing values http://pandas.pydata.org/pandas-docs/stable/missing_data.html , lists many possible techniques interpolate missing values known part of dataset. but in case, think it's better remove 2 first features, because doubt there interpolation missing values, when have such big amount of them, more half of values. but may try fix third feature missing values.

i have normal sort what difference normal sort , bubble sort? there not bubble method? what difference , bubble sort? see documentation array.sort . here's does: this method uses introspective sort (introsort) algorithm follows: if partition size fewer 16 elements, uses insertion sort algorithm. if number of partitions exceeds 2 * logn, n range of input array, uses heapsort algorithm. otherwise, uses quicksort algorithm.

i have phonegap app , want my app users access api getting data. i using php end. what did created key , authenticating key on server. key hard-coded in app meaning can @ code , figure out key , pass parameter , gain access api don't want. furthermore key seen using proxy. is there way dynamically generate key on both app , server gets authenticated? or other way. i don't want user give kind of username/password. i don't want user register or login..the user has no role in authentication..i authenticating app . yes sure can done, but several things before should start. create new table store api keys going generate per user when registering through app . php side: grab users password or unique thing eg: udid andriod, in ios have restricted access udid , might have store unique generated id in keychain . then when have password , udid can put them (or anyway want) , encrypt sha1 (or encryption algorithm) , save api key table ev
