i have array of objects i've created parsing json string: var measurementdata = @html.raw(jsonconvert.serializeobject(this.model.item1)); var stringifieddata = json.stringify(measurementdata); var parseddata = json.parse(stringifieddata); this gives me number of objects, depending on model, looking this: now question is, how add these google line chart without having hardcode datatable? this i've got now, works somewhat: var data = new google.visualization.datatable(); data.addcolumn('string', 'timestamp'); data.addcolumn('number', selectedmeasurements); data.addrows([ [parseddata[index[0]].timestamp, parseddata[index[0]][selectedmeasurements]], [parseddata[index[1]].timestamp, parseddata[index[1]][selectedmeasurements]] ]); chart.draw(data, options, { isstacked: true, vaxis: { viewwindowmode: 'explicit', ...

what best way copy memory x indexes many locations within single array in c? the problem trying solved emulated memory cpu emulator. original hardware has type of memory mirroring, , attempting replicate via code. say have array: int memory[100] = {0}; and have 10 indexes mirrored @ different locations. example if memory[0] changed, index 0, 10, 20, 30... should change value or if memory[3] changed, index 3, 13, 23, 33 should mirrored. likewise if mirrored location changed other mirror locations should reflect this, such if index 23 changed, 3, 13, 23, 33... etc should reflect this. another requirement way specify start , ends of mirrored locations are. example index 10-19 mirrored @ index 30-39, again @ 70-79 leaving unmodified space in between segments of mirrored indexes. would using memcpy fastest/most efficient way of achieving if this, or sort of iterating loop , pointer math better efficiency? how pointer math done calculate start address copy destination? ar...

i have bunch of squares , each has specific identity/symbol need identify. far have like: #include <iostream> #include <windows.h> using namespace std; int main() { hdc dc = getdc(0); colorref color; int sum, x, y; while (true) { sum = 0; sleep(100); (x = 512; x < 521; x++) { (y = 550; y < 565; y++) { color = getpixel(dc, x, y); sum = getrvalue(color) + getbvalue(color) + getgvalue(color); } } cout << "sum: " << sum << endl; } return 0; } obviously scans 1 block far. problem somehow though it's on 100 pixels, takes insanely long time. can't imagine going on. takes on second, maybe 2 seconds, each repetition. can do? there has faster way this. if can't query individual pixels, there way region of screen? zone not inside program's window.

i'm new java, , i'm i'm not using lists properly, i'm saving loads of user input responses elements of string list (as side question, want string list or array list task?), , later want print out these elements @ end of program. however, want automatically through loop, don't know length of list make loop job. tried for(int j = 0; j <= (results.length-1); j++){ where "results" name of string list, it's giving me error "cannot find symbol." there way length of string list in java? , using list thing properly, or should trying array list instead? appreciated. if, length, mean total number of elements contained in list, can use size() method. returns integer specifies number of elements present in list. as for loop, can this: for (int j = 0; j < results.size(); j++) { //write loop logic here }

i want loop on data, , create dynamic maps can later push more data into. example: #foreach ($item in ["bob","john","andy"]) #set(${item}_map = {}) #end so later can this: $!bob_map.put("${foreach.count}", "${some_data}") i do: #foreach ($item in ["bob","john","andy"]) <div id="${item}_map" ></div> #end so later can in js: <script> var map; function initmap() { map = new google.maps.map(document.getelementbyid('bob_map'), { center: {lat: -34.397, lng: 150.644}, zoom: 8 }); } </script>

i new cdi, tried find solution question, but, couln't found any. question suppose have 1 class being injected(a) from, value(topass) getting injected, want pass same value(topass) class b, getting injected class a. public class { string topass = "abcd"; // value not hardcoded @inject private b b; } public class b { private string topass; public b(string topass) { topass = topass; } } can please me in this? note: cannot initialize topass variable of b in same way have initialized in a, there restriction it. in spring have done easily, but, wanted in cdi. you have options: 1. set topass variable b @postconstruct method of bean a : @postconstruct public void init() { b.settopass(topass); } or 2. create producer topass variable , inject bean a , b . producer: @produces @topass public string producetopass() { ... return topass; } injection: @inject @topass string topass; or 3. if b...

i want add store credit app fiverr or other online marketplaces have users can have credit or money in accounts. there gem or recommended steps me build this? credit little intense because have balance actual money. when world, need make sure app works properly. nonetheless, you'd have set model , other things working. the 2 aspects require storage (a model) , payment (mechanics accept money). these permit app accept payments, , have way store them (giving balance work with). the setup not overly complicated; you'll have payments model literally store money user has sent - you'll able balance through user model: storage #app/models/user.rb class user < activerecord::base #columns id | username | email | etc etc etc has_many :payments def balance payments.sum(:value) #-> @user.balance -> "25" end end #app/models/payment.rb class payment < activerecord::base #columns id | user_id | value | currency | t...

camel learner here. there ability store incoming query parameters , set various headers/query parameters various routes? want build proxy-like service authentication option. example : 1) receive http on http://foo.bar/path?login=admin&password=admin&action=delete 2) i'd use <to uri="direct:auth"/> send request http://auth.foo.bar/login?login=admin&password=admin , receive authentication token answer 3) then, perform action token : going http://action.foo.bar/perform?authtoken=sometoken&action=delete finally - there option "cut" "action" param before going auth route , append before going action . thanks. you'll want use camel jetty component receive http request , camel http4 component make requests other web services. the jetty component take query parameters client's call , put them in headers of in exchange same names http query. you can set query parameters used other http calls settin...

i have following c++ code: typedef std::list< volume >::iterator pvolume; typedef std::list< pvolume >::iterator ppvolume; void node::delvolume( pvolume _volume ) { for( ppvolume = m_volumes.begin( ); != m_volumes.end( ); ) if( (*it) == _volume ) { = m_volumes.erase( ); break; } else it++; } it gets error unhandled exception @ 0x009a3c79 in delone3d.exe: 0xc0000005: access violation reading location 0xfeeefef2. exactly when erasing. debug shows neither "it" nor "_volume" null pointer. what other reasons may occur for? the code show correct, seems there's problem elsewhere in application. memory pattern 0xfeeefef2 (a few addresses above 0xfeeefeee ) indicates freed dynamic memory, see here . you can massively simplify code, way: // std::list, in example m_volumes.remove(_volume); // std::vector , std::deque auto itr = std::remove(m_volumes.beg...

i have chrome opening in kiosk mode - added --kiosk flag chrome shortcut works expected. the kiosk allows browsing of our intranet , internet . realise can use javascript redirect pages on our intranet, internet? don't want people fpr example browsing youtube , walking away. we have browser re-direct www.mydomain.com after x minutes of inactivity. i have tried kiosk here require swipe left/right gestures don't seem work page navigation (already contacted developer via github). any suggestions? i managed find answer question on another site . ended using chrome extension called idle reset . hopefully helps else.

i'm using simpleform in rails , have 2 fields presented user choose location (a rich association) pre-filtered set of locations. each choice needs saved in join table along type of location is. how can create form send info controller can tell me 'type' of location being selected. _new_flow_form.html <%= simple_form_for @new_flow,:url => {:action => "company_create_flow", :controller => 'flows'}, :html => { :class => 'form-horizontal', :multipart => true } |f| %> <%= f.label 'workflow title', :class => 'control-label' %> <%= f.text_field :title, :class => 'form-control' %> <%= f.association :locations, collection: location.where(:company_id => @company.id, :source => 'true'), :label => 'source location' %> <%= f.association :locations, collection: location.where(:company_id => @compa...

i have 2 processes created named pipe. writer process writes message using write(), , reader process reads message read(). noticed read() blocks when writer closes pipe. possible let writer process sends eof before closing pipe reader not blocked? not... it's not possible send eof because eof nothing maps sent on channel. eof condition (yes, it's condition, not receive or send on channel) means there's no more data read(2) , it's got process making read(2) return 0 characters read. many reads in eof condition, return value of 0 meaning there's no more data. by way, pipes block readers when there's no data available, but, writer still there send more data, there's no eof condition. design, pipes block readers when there's no data available (but writer still has pipe open) , block writers when there's no more space put data in fifo (this happens when there readers fifo open, none of them reading) see it's feature, not bug...

i'd cite article in figure caption. i've tried using rmarkdown/pandoc [@citekey] , latex \\citep{citekey} forms in fig.cap chunk option without luck. here reproducible example: --- output: rmarkdown::tufte_handout references: - id: nobody06 title: 'my article' author: - family: nobody given: jr issued: year: 2006 --- text [@nobody06]. ```{r figure, fig.cap="a figure [@nobody06]"} library(ggplot2) qplot(1:10, rnorm(10)) ``` # references this produces correct citation in text block either [@nobody06] (when use rmarkdown form) or (?) (when use latex form) in figure caption. here screencap: . i have tried reference in .bib , .bibtex file follows, same results: @misc{nobody06, author = "nobody jr", title = "my article", year = "2006" } after updating dev versions of rmarkdown ( rstudio/rmarkdown@c22ee06 ) , knitr ( yihui/knitr@b510ced ) (?) both in text block , figur...
