it's not crucial question, i'm still wondering, when it's possible have mysql connection settings some-user@localhost no-password. it's potential risk in case of shared web-provider: other user can access database (if know some-user name). is risky in case of vps(vds)? if run own server ip, assume approach safe? wrong? mimic localhost ip outside?

i wondering, how define constraints regex route, match if excludes every single element of group. for instance, so: get "list/:action", :constraints => {:action => [none of following: (new, edit, delete, update)} i know if want match of elements of list, have defined so: get "list/:action", :constraints => {:action => /(new|edit|delete|update)/}, don't know, how make work described above. i have tried using ^ , ! signs before group, no luck far - there has notation one, think. how exclude these elements ? try following. it'll exclude actions route. class excludeactions def matches? ["new", "edit", "delete", "update"].exclude? params[:action] end end "list/:id", :constraints => excludeactions.new this exclude new , edit , delete , update actions routes list

i working on silverlight application. have view allows user add new object. viewmodel bound view has collection of object type property. constructor of viewmodel has function, getdata() calls wcf service , fetches data database, adds fetched list collection. after adding new object database through wcf service, method getdata needs called again refresh collection having latest data in collection necessary. this process little slow every time 1 adds anything, entire data tables need fetched again. can more slower data grows more , more large , when joining of multiple tables may required data. i thinking of adding object pass service add database, directly collection in viewmodel. obviously, add object collection when service called has not returned error make sure has been added db. way can have latest data in collection without need fetch database. can 1 point out drawback approach or scenario may fail? also, please suggest if there other better ways of achieving goal.

i have 2 sequences, can vector or list. want return sequence elements not in common 2 sequences. here example: (removedupl [1 2 3 4] [2 4 5 6]) = [1 3 5 6] (removeddpl [] [1 2 3 4]) = [1 2 3 4] i pretty puzzled now. code: (defn remove-dupl [seq1 seq2] (loop [a seq1 b seq2] (if (not= (first a) (first b)) (recur (rest b))))) but don't know next. i encourage think problem in terms of set operations (defn extrasection [& ss] (clojure.set/difference (apply clojure.set/union ss) (apply clojure.set/intersection ss))) such formulation assumes inputs sets. (extrasection #{1 2 3 4} #{2 4 5 6}) => #{1 6 3 5} which achieved calling (set ...) function on lists, sequences, or vectors. even if prefer stick sequence oriented solution, keep in mind searching both sequences o(n*n) task if scan both sequences [unless sorted]. sets can constructed in 1 pass, , lookup fast. checking duplicates o(nlogn) task using set.

i using complementary filter sensor fusion. equation complementary filter using is angle=(1-alpha)*(angle+gyro*dt)+(alpha)*(accel_mag_angle) i have confusion calculation of alpha. read somewhere alpha calculated using formula alpha= da/(da+dt) where da rate @ want values change (which refers cutoff frequency of filter) , dt sampling time. using sensor_delay_ui. sampling rate of ui around 15hz. used alpha=0.2(by trial , error method) , app worked fine. later realised according equation cannot use alpha=0.2(theoretically) since give me cut off frequency of 60hz , sampling frequency 15hz. cut off frequency calculation wrong ? or understanding of equation wrong ? i wouldn't sweat it. if find alpha=0.2 satisfactory trial , error, use it. filters have tuned in practice anyway. theory helps start (usually) cannot avoid tuning. i don't see wrong 60 hz cut off frequency. means motions above frequency cut off. , thing, since noise anyway.

i'm implementing bfs on 2d-array list serve "queue". add each unvisited neighbor of current cell(i, j) queue, , in each loop, pop head of queue current cell, until queue empty. standard stuff. the problem seems 1 "if" statement executed in each loop. can't see why happens. for tgroup in targets.keys(): #group of targets t in targets[tgroup]: #each target in group visited = [[false]*len(cells[0])]*len(cells) queue = [] cur = none queue.append(t) visited[t[0]][t[1]] = true cells[t[0]][t[1]].fields[tgroup-3] = 0 while len(queue) > 0: cur = queue[0] queue = queue[1:] if cur[0] > 0 , visited[cur[0]-1][cur[1]] false: queue.append((cur[0]-1,cur[1])) visited[cur[0]-1][cur[1]] = true cells[cur[0]-1][cur[1]].fields[tgroup-3] = min(cells[cur[0]-1][cur[1]].fields[tgroup-3], cells[cur[0]][cur[1]].fields[tgroup-3]+1

i developed application based on mean stack , works fine when ui , api on same domain-port. , when segregate ui , api , let deploying on different domain or local different port ,all api call successful no response data. fyi have access-control-allow-origin * , without behaviour same. as in case of cross origin browser first sends option request. if in response of option request if access-control-allow-origin found sends actual request, else gives cros error. you can add these lines of in app.js of nodejs code. solve purpose. app.use(function(req, res, next) { res.setheader('access-control-allow-headers', 'origin, x-requested-with, content-type, accept'); res.setheader('access-control-allow-methods', 'post,head,get,put,delete,options'); res.setheader('access-control-allow-origin', '*'); next(); }); app.options('*', function(req, res, next) { res.send(); });

i'm starting use d3 , i'm trying work example using own json. code not showing error doesn't show pie, don't know can be. this code: <!doctype html> <html> <head> <meta charset="utf-8"> <title>step 1 - basic pie chart</title> </head> <body> <div id="chart"></div> <script type=text/javascript src="{{url_for('static', filename='d3.min.js') }}"></script> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script> <script> (function(d3) { 'use strict'; var width = 360; var height = 360; var radius = math.min(width, height) / 2; var color = d3.scale.category20b(); var svg = d3.select('#chart') .append('svg') .attr('width', width) .attr('height',

if i'm not wrong, think error mean i'm trying display doesn't exist. i've provided content, don't know why error. i'll explain in detail: i'm using django-ckeditor, , when try post image , text, grouped content. , i'm trying use image thumbnail front page, separate content. i'm using python goose extract image content. in models.py class post(models.model): content = richtextuploadingfield(config_name='default') @property def thumbnail(self): g = goose() thumbnail = g.extract(raw_html=self.content).top_image.src return thumbnail in html <img src="{{ post.thumbnail }}" /> the error dissapears if def thumbnail(self, content) (and nothing gets displayed) shouldn't since i'm extracting post model, , content self.content.

i have problem animations of uicollectionview on different batch updates. i'm using code: [collectionview performbatchupdates:^{ if (touched) { [collectionview deleteitemsatindexpaths:markeditems]; [collectionview insertsections:newsec]; } else { [collectionview deletesections:newsec]; [collectionview insertitemsatindexpaths:markeditems]; } } completion:nil]; here's video of i'm trying , problem . idea when touch on image it'll animate top, new main image , fade other images. problem is, when go , touch other image it'll animate new touched image and previous image. i believe it's uicollectionview bug , can't figure out workaround. here's sample project , if want. i contacted apple. engineers said it's bug in uikit , there's no know work around , should wait next major ios preview releases (ios 7) check if fixes problem.

my case this: ... success:function(data) { jquery.each(data.searchcityresponse.nation.city, function(key,value) { console.log(value.citycode); city.append(jquery("<option value.citycod==\'ceb\')?\'selected\':\'\'></option>").val(value.citycode).text(value.cityname)); }); city.select2(); } ... i check in console: http://imgur.com/jio8nyk this seems problem writing ternary "<option value.citycod==\'ceb\')?\'selected\':\'\'></option>" string , it'll not parse variable or javascript operator. also, there typo, citycod should citycode . you can use concatenation + operator "<option " + (value.citycode === 'ceb' ? 'selected' : '') + "></option>" or, selected status can kept in variable , variable can used. var selected = value.citycode === 'ceb' ? 'selected' : '&#

i have notification @ specific time, see code: //create alarm manager alarmmanager alarmmgr0 = (alarmmanager)getsystemservice(context.alarm_service); //create pending intent & register alarm notifier class intent intent0 = new intent(this, alarmreceiver_maandag_1e.class); intent0.putextra("uur", "1e"); pendingintent pendingintent0 = pendingintent.getbroadcast(this, 0, intent0, 0); //set timer want alarm work (here have set 8.30) calendar timeoff9 = calendar.getinstance(); timeoff9.set(calendar.hour_of_day, 8); timeoff9.set(calendar.minute, 30); timeoff9.set(calendar.second, 0); //set timer rtc wakeup alarm manager object alarmmgr0.set(alarmmanager.rtc_wakeup, timeoff9.gettimeinmillis(), pendingintent0); this works perfect except 1 thing. the notification set 8:30 alarm manager if launch app after 8:30, 9:00 example, notification still shows.. is there possibility alarm goes off @ 8:30 not later? edit for having same problem, here

i planning on having activity 2 check boxes. want tasks when screen off in background continuously based on user check marks. final checkbox checkbox = (checkbox) findviewbyid(r.id.checkbox_id); if ( checkbox1.ischecked() && myserviceisntrunning() ) { startservice(myservice1.class) if ( checkbox2.ischecked() && myservice2isntrunning() ) { startservice(myservice2.class) } if both checkmarks checked, wan't both tasks run in background forever using method. there harm in launching both services @ once? there doesn't appear documentation in optimization tips documentation, , saw page it: can start 2 services same activity , can run activity , 2 services parrallely in android? . so, starting 2 services parallely forever idea? as long not conflict, ok have more 1 service running. battery life , memory may affected, depending on code. if possible, can consider merging them 1 service handle 2 tasks.
