i have backbone app, uses backbone.history.start({pushstate: true}). render pages based on url change, , forward buttons work fine, views rendered well. there problem though, page scroll positions are't kept when click or forward button. makes feel bad. i thought keep array of pages visited , store scroll position each of them. listen if user click back/forward , load appropriate scroll position. but. i found out unable tell when user click or forward button. if could, read stored scroll position of previous page , apply it. doing wrong? you store scroll location part of route, using like: router.navigate('/my/route/scroll/[my_scroll_location]', {replace: true}); so won't add new history point, modify current one. way, when hit "back" go previous "page"/route, , hitting "forward" have enough information scroll right point.

so far i've come across - setting ejabberd cluster in master-slave configuration, there single point of failure , people have experienced issues when after fixing master (if goes down), cluster doesn't become operable again. sometimes, ejabberd instances of every slave have revisited again them working properly, or mnesia commands have in-putted again make master communicate slaves. setting ejabberd cluster in multi-master configuration of nodes can taken out of cluster without bringing whole cluster down. basically, there no single point of failure and, way in official documentation ejabberd tells via join_cluster argument expose in ejabberdctl script. however, in case, data replicated across both nodes big performance overhead in opinion. so boils down this. what best/recommended/popular mode in ejabberd cluster of 2 nodes should set respect performance keeping other critical factors (fault tolerance, load balancing) in mind well. there single...

when choose between using 2 fragments , replacing 1 other in activity (or child fragments in fragment) or using 2 views , changing them using viewswitcher (or viewflipper)? for example, while loading data, use loading view, , want change main view. it depends on app structure. viewswitcher may work, not best way this. option not fragment @ all, change content of activity, calling again setcontentview(int) layout resource of main view, once loading complete.

i work out project scratch. these days, have been assigned template matching project includes image handling besides other things do. plan code project in java. want complete reference of java language constructs 1 way or related image handling. don't want know third-party library core java ones. references based on java se 8 preferred. i'd start @ bufferedimage , imageio (links java se 8 docs). a bufferedimage sounds - image buffer of rgb information. can use imageio deal various file formats - no need write code png, bmp, jpg, or other formats. imageio.read loads image image file, , imageio.write formats bufferedimage object whatever file format want.

i'm bit confused on why i'm seeing difference between 2 statements. i'm trying increment int column 1, setting values 1, 2, 3, 4, etc.: query #1 produces desired result: declare @a int set @a = 0 update #jc_temp set num = @a, @a=@a+1 query #2 sets rows 0: declare @a int set @a = 0 update #jc_temp set num = @a set @a=@a+1 obviously i'm missing here, naked eye appear same. local variable rollback somehow in 2nd query? because second "update" two separate statements : 1 - declare @a int 2 - set @a = 0 3 - update #jc_temp set num = @a 4 - set @a=@a+1 the update sets rows value of @a (which 0), next statement increments @a . your first update : 1 - declare @a int 2 - set @a = 0 3 - update #jc_temp set num = @a, @a=@a+1 increments value of @a for each row , see increments in data.
