i have 2 tables. in first table have table rows generated ng-repeat ng-click events. ng-click make request , output data in second table. second table empty first, , getting populated when `m clicking table rows first table. how can make request first table row (first table), or pre click , or pre select, can output default data in second table ? table1 <tr ng-repeat="task in todos" ng-show="todos.length > 0" ng-click="updatetaskinfo(task)> <td ng-bind="task.stuffs"></td> </tr> table2 <tr ng-repeat="stats in statsfromtable1" ng-show="statsfromtable1.length > 0"> <td ng-bind="stats .stuffs"></td> </tr> so table2 first empty, , when click table rows table1 make request, , pass data in table2. problem: how can have default data in table2, such data first, or second table row in table1 ? you can use ng-init directive https://docs.angula

is possible prevent in-call status bar affecting app's views? i in-call status bar ideally appear on top of view , not affect frame (neither changing height nor changing origin , pushing view down). is possible? answering own question, best solution able find manually change main view's frame start @ origin , have size of entire screen (both width , height). way, receive same effect if use navigation controller example, view remains in place , in-call status bar appears on top of (on different layer, without affecting app view's display).

i studying read_lock , write_lock. it seems can use spin_lock instead of read-write lock. so wondering there advantages use read-write lock when use read_lock , write_lock, advantages using spin_lock? short googling turned paragraph up: sometimes, lock usage can divided readers , writers. example, consider list both updated , searched. when list updated (written to), important no other threads of execution concurrently write or read list. writing demands mutual exclusion. on other hand, when list searched (read from), important nothing else write list. multiple concurrent readers safe long there no writers. task list's access patterns (discussed in chapter 3, "process management") fit description. not surprisingly, task list protected reader-writer spin lock. (source: link ) so basically, using read_lock/write_lock gives more power regular spinlocks deny/allow different lock-users, depending on needs, in above example.

while implementing new android m permission model noticed permissions dialog not respect theming of styles.xml. in styles.xml override dialog , alertdialog style this: <item name="android:dialogtheme">@style/theme.dialog</item> <item name="android:alertdialogtheme">@style/theme.dialog</item> is possible change theming? or because system dialog in device settings? no, it's not possible. permissions dialog system dialog , hence can't change theme: the m developer preview introduces new app permissions model streamlines process users install , upgrade apps. if app running on m preview supports new permissions model, user not have grant permissions when install or upgrade app. instead, app requests permissions needs them, , the system shows dialog user asking permission.

this interesting. flash cs6 has lost ability iterate through objects , delete values (which did work before) delete values object keys for each(var key:string in scorekeep.scorecard) scorekeep.scorecard[key] = 0; the object (scorekeep.as) static public var scorecard:object = { "fish":6, "golfball":2, "gloves":8, "boot":4, }; you can trace object key. value still there. you using wrongly, not supposed for each for . for each take value, not key. you have " , " after last prop in object, assume that's typo (and should result in compile-time error).

why git not allow delete branches aren't in current branch's ancestral history? is because git doesn't have access them in object storage? git allow delete unmerged branch using git branch -d <branch-name> . reason refuses when branch name not merged (using lowercase -d ), reduce accidents throw away work meant merge. git can delete branch, wants sure you're doing meant do.
