i have listview . updated adapter, , call notifydatasetchanged() . want wait until list finishes drawing , call getlastvisibleposition() on list check last item. calling getlastvisibleposition() right after notifydatasetchanged() doesn't work because list hasnt finished drawing yet. hopefully can help: setup addonlayoutchangelistener on listview call .notifydatasetchanged(); this fire off onlayoutchangelistener once completed remove listener perform code on update ( getlastvisibleposition() ) mlistview.addonlayoutchangelistener(new view.onlayoutchangelistener() { @override public void onlayoutchange(view v, int left, int top, int right, int bottom, int oldleft, int oldtop, int oldright, int oldbottom) { mlistview.removeonlayoutchangelistener(this); log.e(tag, "updated"); } }); madapter.notifydatasetchanged();

if have struct this: /* defined structure 3 integer members */ typedef struct mystruct mystruct; struct myscruct{ int x; int y; int z; }; int main() { mystruct example; // declared "example" type "mystuct" example.x=1; // member 1 have value 1 example.y=2; // member 2 have value 2 example.z=3; // member 3 have value 3 char c; printf("\nchoose witch member want print [ x, y or z]"); scanf("%c", &c); while(getchar() != '\n'); printf("%d", example.c); // part don't know possible. return 0; } it possible pass different member last printf instead of use combination of if example? if so, what's syntax of it? no, cannot use runtime data reference symbols source code. can accomplish apparent aim of particular code bit more effort, though: typedef struct mystruct mystruct; struct myscruct{ int x; int y; int z;

let's have log of events of ad displays , ad clicks stored via logstash in elasticsearch , displayed in kibana 4. calculate simple metric ctr (click-through-rate) of events , : ctr = #clicks/#displays. first of all, know if it's possible in elasticsearch + kibana? don't see possibility in kibana. thinking doing in raw elasticsearch scripted aggregation . don't know how define such in kibana. any ideas on how welcome! comments explaining it's impossible valuable. kibana 4 includes support elasticsearch scripting. can go settings > indices (pick pattern) > scripted fields , add new scripted field computes ctr. take @ " scripted fields " @ elastic blog more info.

i need ideas on how implement simple undo function. spring web-app js frontend , typical spring rest api. undo feature should work similar undo in google keep, e.g. user clicks delete, ui appears delete object, small popup appears in corner undo link approximately 10 sec, after disappears , undo no longer available. my initial thoughts use async message queue. perhaps commandqueue , undocommandqueue. when message enters commandqueue delayed 10sec. after delay service activator recieves message , checks see if there corresponding undo message in undocommandqueue matching id, if not proceeds delete. if possible(and not more complicated) i'd avoid using msg queue. perhaps async delete method has 10 sec sleep built in. how notify async method after it's done sleeping separate undo rest api call made? i know command pattern de-facto approach undo, given want 1 level of undo short amount of time seems overkill. simplest solution delay delete api call altogether using
