i trying create cart type order page in emberjs. this looks http://emberjs.jsbin.com/qanujodo/3#/tickets when clicked on add 1 ticket model saves ticketquantity, , when added 1 more adds model duplicating model records. what want is, when ticketquantity changes update data store record , if same tickettype record present remove records , save current record based on ticketquantity . currently when add 1 adds record data store, , if added more record stored previous records not deleted. should true tickettypes. ideally should pointed out rwjblue in #emberjs irc, ticketcontroller should keep track of order creates , create once, incrementproperty/decrementproperty needed on subsequent cliks on add one/decrease 1 button. how go ? check out: http://jsbin.com/giticexa/3#/tickets didn't touch ui, can see model either created if not present or increment existing model if 1 matches. best of luck!

i have custom angular directive graphically represents “activity” in webapp. use this: <activity-box ng-repeat="act in activities" model="act" active="{{currentactivity == act}}" /> my directive has isolated scope , declares model , active this: appdirectives.directive('activitybox', function() { return { template: '<div ng-class="{activityactive: active == \'true\'}">{{model.name}}</div>', restrict: 'e', replace: true, scope: { model: '=', active: '@' }, link: ... }; }); i have no worry model attribute, active attribute treated string. when currentactivity == act true, active holds string value "true" (and not boolean true ), or else, "false" (and not false ). this means although conceptually boolean, must treat string. instance, i'd write ng-class=...

my android app sends http request servlet on jetty server , receives response. worked fine in jetty 6.1.26. works fine in jetty 7.6.13( uses servlet-api-2.5.jar) , jetty 8.1.15( uses servlet-api-3.0.jar) when deploy exact same servlet jetty 9.1.5.v20140505(which uses servlet-api-3.1.jar) on same machine, results in socket timeout in android app. use java jre1.7.0_55. in android app, connection timeout 3000 , socket timeout 5000. if increase socket timeout 30,000, makes no difference. if set 40,000 works. any idea what's going on? why android code take time accept servlet response jetty 9? removing response.setcontentlength() in servlet resolved issue. sending 30 characters response, had set length 1024. guess android app expecting more data looking @ length set in response, waits till kind of timeout happens. apparently, servlet 3.1 in jetty 9 behaves differently previous versions.

what best way user-defined custom name of android device? some phones treat both device name , bluetooth name same. in these cases bluetooth name. in phones there setting called owner info , under security->settings . how can read name that? or there else suggest scenario? understand i'm not asking profile name people app or model / manufacturer of phone. i have posted this answer before: use string ownerinfo = settings.secure.getstring(getcontentresolver(), "lock_screen_owner_info"); make sure catch settingnotfoundexception update as of android 4.4.2 owner info value moved lock screen database, /data/system/locksettings.db , 3rd-party apps have no read/write access. that's, there no reliable way of reading owner info later android versions.

i have inter-node encryption setup on small cassandra cluster (4 nodes), , each node has own key pair. means need distribute trusted keystore nodes contains public key every other node in cluster, makes bit of pain update when add nodes cluster. does cassandra allow using single certificate/key nodes in cluster, or complain? docs see online tell me generate separate key pair each node, not address sharing certificates. if allowed, drawbacks method? adding ca cert truststore of each node sufficient.

if create breakpoint using xcode's breakpoint navigator (cmd-7), , invoke lldb debugger, can see breakpoints in debugger using lldb command breakpoints list . however, if create breakpoint using lldb debugger directly, instance doing breakpoint set --name 'viewdidload' , not see new breakpoint reflected in xcode. similarly, if enable/disable breakpoints lldb directly, not reflected in xcode. in other words, seems xcode not see lldb breakpoints did not create. xcode not faithful interface lldb. this seems quite busted. there way tell xcode refresh understanding of lldb, picks changes lldb's breakpoint configurations made directly? there not way yet. if able so, please file bug @ bugreporter.apple.com. bug duped, bugs votes features , 1 hasn't gotten done yet because far there's been more important in front of on stack.

i understand usual "task not serializable" issue arises when accessing field or method out of scope of closure. to fix it, define local copy of these fields/methods, avoids need serialize whole class: class myclass(val myfield: any) { def run() = { val f = sc.textfile("hdfs://xxx.xxx.xxx.xxx/file.csv") val myfield = this.myfield println(f.map( _ + myfield ).count) } } now, if define nested function in run method, cannot serialized: class myclass() { def run() = { val f = sc.textfile("hdfs://xxx.xxx.xxx.xxx/file.csv") def mapfn(line: string) = line.split(";") val myfield = this.myfield println(f.map( mapfn( _ ) ).count) } } i don't understand since thought "mapfn" in scope... stranger, if define mapfn val instead of def, works: class myclass() { def run() = { val f = sc.textfile("hdfs://xxx.xxx.xxx.xxx/file.csv") val mapfn = (line: string)...

tl:dr; there way select table names case insensitive on jdbc? i try extract table names database on jdbc connection. can resultset tablesrst = connection.getmetadata().gettables( null, null, null, null ); this, however, returns tables, views etc. need first 10 match pattern. know can build myself manipulating arguments. the case of pattern matters, cannot find table aap if pattern a% . is there easy way query table names on jdbc, without having resort database-specific code? that depends on database configuration. if turn off case sensitivity on database, i'm assuming aap come a%.

i'm having issues javascript code. need make code following: click image twice within 3 seconds make image disappear click once reappear i've got close working...i'm having issues date. don't know how keep date first click. code right creating new start date each click don't want. code far: var imgnext = -1; var start = new date ( ); function disappear () { var end = new date (); imgnext++; if (imgnext == 2) { document.getelementbyid("mypicture").style.visibility="visible"; imgnext = -1; } if (imgnext == 1 && (end-start <3000)) { document.getelementbyid("mypicture").style.visibility="hidden"; } start = new date (); } in code image changes if clicks on 3 seconds apart because i'm creating new start date every time function triggered. how resolve this? cheers. here answer, working example: http://jsfiddle.net/ys5bs/2/ document.getelementbyid("disappear").on...

i have 3d array arr1[16][8][9] , want assign contents of array 1d array arr2[36] . i'm trying: arr2[0] = arr1[0][0][0]; arr2[1] = arr1[0][0][1]; ...... arr2[8] = arr1[0][0][8]; i'm calling function: func_arr(int arr2[36], int arr1[16][8][9]) the function declaration goes like: void func_arr(int arr2[36],int arr1[][8][9]); but array assignment seems invalid. better approach it? function calling seems incorrect. replace below line func_arr(int arr2[36], int arr1[16][8][9]) with func_arr(arr2, arr1); type of first function argument int [36] , passing arr2[36] . assuming arr2 int arr2[36] , type of arr2[36] int , type mis-match. arr2[36] int located @ address after arr2 ends.
